無料のGPT-3.5のChatGPTで大学入試レベルの英作文を自学自習するためのプロンプト
https://yanase-yosuke.blogspot.com/2023/06/gpt-35chatgpt.html
追記（2023/11/06）
入力する英文が大量になるとChatGPTの作動が不安定になることが確認されましたので、出力（フィードバック）の種類を減らした簡易版 (Ver. 3.5) を下に追加しました。これまでのVer. 3.4 も引き続き掲載していますので、もし入力する英文が100 words程度でしたら、学習により親切なVer. 3.4を引き続きご使用ください。
■ 効果
このプロンプト (Ver. 3) は、学習者（大学レベル以上）が学術英語執筆を自学自習することを助けます。
下のプロンプトの指定欄に英文を入れると、ChatGPTが以下の7つを出力します。（Ver. 3.6は、2), 3), 4), 6) のみを出力します）。
1) 入力したオリジナル英文
2) 語法（＝文法・句読点・綴り）だけを添削した英文
3) その語法添削のポイント
4) 語法添削した英文を米国の大学入学レベルに改善した改訂英文
5) 学術英語としての改訂のポイント 1（上の 4) の解説）
6) 語法添削した英文を学術ジャーナルに掲載する文章として適切なレベルに改善した改訂英文
7) 学術英語としての改訂のポイント 2（上の 6) の解説）
8) 英文執筆者へのコメント
Ver. 3では2つのレベルでの英文改訂例を学習者が見ることができます。これにより学習者は自分に適した英文改訂をしやすくなります。
なお、このプロンプトはChatGPTのGPT-4を前提としています。GPT-3.5やBingやBardでも使えますが、出力の質は低いです。
■ プロンプト
2023/06/05版 (Ver. 2.1)：役割部分などで作文の要求水準を少し下げるように指示。定義部分では、短縮形や2人称代名詞やrun-on sentencesや付加疑問文を避ける指示を追加。
2023/06/09版 (Ver. 2.2)：Ver. 2.1の英語レベル要求水準をVer. 2のレベルに戻しました。Ver. 2.2は、米国の大学生が書く学術英語レベルで英文を改訂します。
2023/06/12版 (Ver. 2.2.1)：OUTPUTの項目の間に "Two blank lines"を入れて、出力画面が見やすくなるようにしました。
2023/06/14版 (Ver. 2.2.2)：英語のレベル要求水準を少し下げました。同時に冗長と思われるprompt表現を整理しました。
2023/06/16版（Ver. 3)：改訂のレベルを2つに分け、まずは米国の大学入学時点に要求されるレベルで改訂された英文を出力し、次に学術英語としてふさわしいレベルでの改訂を出力するようにしました。
2023/06/24版 (Ver.3.1)：# ROLEの項目にPlain Languageの記述を加えました。
2023/06/26版 (Ver.3.1.1)：Academic English Writingの特徴のうち、ChatGPTにとって自明と思われるものは削除してプロンプトを少し軽くしました。
2023/06/28版 (Ver.3.2): Plain Languageの記述を# TASKSの項目にも加えました。
2023/07/11版 (Ver.3.3)：Academic Englishの特徴の記述を簡略化しました。
2023/07/20版 (Ver.3.4)：これまでRevision Pointを一括して出力していたのを改め、2つのRevisionそれぞれに対して改訂のポイントを提示するようにしました。
2023/11/06版 (Ver.3.5)：大量の英文を入力してもChatGPTの動作が不安定にならないようにするため、出力を原文・添削文・改訂文（大学入学レベル）・改訂文（学術誌レベル）の4種類に絞りました。なおVer. 3.4も引き続き掲載しています。
2023/11/09版 (Ver. 3.5.1): 大学レベル改訂のレベルを少し上げ、ジャーナルレベル改訂のレベルを少し下げることを目指しました。具体的には、TASKSのStep 2の "Rewrite" を "Moderately rewrite" に、Step 3の "Rewrite" を "Slighly revise" に変更しました。
2023/11/10版 (Ver. 3.6)：語法添削の箇所とポイントを示す機能を復活させ、学習者が添削から学びやすいようにしました（同時に添削を、綴り・文法・句読法に集中するようプロンプト表現を改善しました）。その代わり、AIの出力負担を減らすため、オリジナル英文の再生機能を削除しました。

■ 諸注意
出力の正確性について
AIは、時に厳密には正しくない回答をすることがあります。学習者はAIからの出力を無批判的に受け入れず、その正確性や適切性を吟味することが必要です。私の場合は、下に示す授業プロセスで、学習者の判断をチェックして助言するようにしています。
出力の一時停止について
時にChatGPTの出力が一時停止するときがあります。そのときには "Continue Generating" というアイコンをクリックしてください。
■ 私の授業方針
このプロンプトを使う私の授業方針は以下のとおりです。（Ver. 1の記述を再掲）
英語力の定義
英語力は、生身の英語力と機械を使いこなすことで可能になる英語力の合成だと考えます。ただし、機械をこなすためには、相当の生身の英語力が必要です。
授業プロセス
授業のプロセスは以下のとおりです。
1. 学生は授業中にAIを使わずに英語エッセイを書く。ただし辞書の参照や周りのクラスメートとの相談は可能。学生は授業終了時までにエッセイを書いたファイルをLMS (Learning Management System) に提出。
2. 教師は授業終了後に、上のプロンプトを使ってAIで学生のエッセイに対するフィードバックを自動生成する。教師はそのフィードバックをLMSで学生と共有する。（本来はこの過程も学生にやってほしいところですが、現時点ではすべての学生がChatGPT (GPT-4) を使えるわけではないので、教師がやります）。
3. 学生は次の授業でAIからのフィードバックを吟味し、納得できる点および納得できない点を根拠を示した上でレポートにまとめる。根拠はウェブ上のリソースなどから引用する。学生は授業終了時までにレポートを書いたファイルをLMSに提出。
4. 教師は授業終了後に、学生のレポートを読み、ハイライトやコメントでフィードバックを与える。教師はそのフィードバックをLMSで学生と共有する。（次の授業では学生はその教師からのフィードバックを読んだ上で、1の作業に戻る）。

1. Original Text:
Many people love music, but do not know anything about speakers. Do you know that many speakers have holes? They are usually round, but sometimes not round. They are big fluto and make big bass sound. These speakers, by the way, are called ported speakers, because holes are ports. Because of ports, these speakers make big sound although they are not really big in size. People like big bass and company sell these speaker for this reason. But some people like sealed box speakers that doesn't have holes. They know holes are bad for sound. You should know more about speaker. So I'll explain why ported speaker are bad in this essay.
2. Usage Correction:
Many people love music but do not know much about speakers. Do you know that many speakers have holes? These are usually round, but not always. They play a significant role in producing a big bass sound. These speakers are referred to as ported speakers, with the holes being the ports. Due to these ports, these speakers can produce substantial sound even if they are not large in size. People favor the robust bass, and companies sell these speakers for this reason. However, some people prefer sealed box speakers that do not have holes, believing that the holes negatively affect the sound quality. You should understand more about speakers. Therefore, I'll explain why ported speakers are considered unfavorable in this essay.
3. Usage Issues:
- "do not know anything about speakers" should be corrected to "do not know much about speakers" for a more precise description.
- "They are big fluto and make big bass sound" is unclear and has been revised for clarity.
- "because holes are ports" was revised for better readability.
- "these speakers make big sound although they are not really big in size" was corrected for improved English usage.
- "company sell these speaker for this reason" was corrected to "companies sell these speakers for this reason" to maintain plural consistency and correct verb form.
- "that doesn't have holes" was corrected to "that do not have holes" to align with the plural subject 'speakers'.
- "They know holes are bad for sound" has been improved for a more nuanced expression.
- "You should know more about speaker" was corrected to "You should understand more about speakers".
- "I'll explain why ported speaker are bad" was corrected to "I'll explain why ported speakers are considered unfavorable".
4. Revision:
While numerous individuals appreciate music, they often lack a comprehensive understanding of speakers. Did you know that many speakers incorporate holes into their design? Typically round, these holes sometimes deviate from this shape, playing an integral role in generating profound bass sounds. These devices are commonly referred to as ported speakers due to these holes, termed 'ports'. Despite their compact size, these ports enable the speakers to produce substantial sound. The intense bass that these speakers deliver appeals to many, thus prompting companies to market them widely. Conversely, a segment of the audience prefers sealed box speakers, devoid of holes, due to their perception that holes can compromise sound quality. It is imperative to expand your understanding of speakers. In light of this, the ensuing essay will elucidate the drawbacks associated with ported speakers.
5. Revision Issues:
- The first two sentences were rephrased for a more formal tone and to eliminate colloquialism.
- The sentence "They play a significant role in producing a big bass sound" was rephrased to emphasize the function of the holes in sound production.
- The sentence "Due to these ports, these speakers can produce substantial sound even if they are not large in size" was rephrased for smoother flow and improved formal tone.
- The sentence "People favor the robust bass, and companies sell these speakers for this reason" was revised to emphasize consumer preference and company response.
- The sentence "However, some people prefer sealed box speakers that do not have holes, believing that the holes negatively affect the sound quality" was rewritten to provide a balanced perspective.
- The sentence "You should understand more about speakers" was revised to emphasize the importance of knowledge on the subject.
- The final sentence was rephrased to make a more formal and clear statement of purpose for the essay.
Comment:
You have a knack for introducing a topic clearly and setting up an argument, which is a great strength in academic writing. However, pay close attention to grammatical details and the appropriateness of the language you use. Some phrases in your text are informal and might not suit the academic context. To improve your academic English, try to employ more formal language and complex sentence structures. Your writing demonstrates potential, and with continued practice, I am confident that you will be able to express your ideas in a more academic manner.
追記（2023/06/05）
以下は、Ver. 2.1 によるrevisionです。
A considerable number of individuals are fond of music, yet they lack knowledge concerning speakers. One might be surprised to learn that numerous speakers are equipped with apertures. These apertures, typically circular but occasionally of different shapes, contribute significantly to the production of profound bass sounds. Such speakers, distinguished as ported speakers due to the presence of these ports, have the capacity to produce considerable sound despite their moderate size. The profound bass generated by these speakers is widely appreciated, leading companies to market them for this specific characteristic. Contrarily, a segment of audio enthusiasts shows a preference for sealed box speakers devoid of apertures, based on the understanding that these ports negatively impact sound quality. To further understanding of this topic, this essay will provide a detailed analysis of the drawbacks associated with ported speakers.
追記（2023/06/09）
以下は、Ver. 2.2によるrevisionです(GPT-4使用)。
While many individuals appreciate music, their understanding of speakers remains limited. Numerous speakers are equipped with apertures, typically round, though they can exhibit other shapes. These speakers, referred to as ported speakers, produce robust flute-like and deep bass sounds owing to these apertures. Despite their compact size, their design enables them to create amplified sounds. This feature appeals to many, leading manufacturers to market these speakers extensively. Contrarily, a subset of consumers prefers sealed box speakers devoid of apertures, asserting that these enhance sound quality. This essay will further explore the notion that ported speakers may compromise sound quality.

"Many people love music but do not know anything about speakers. Do you know that many speakers have holes? They are usually round, but sometimes not. They are big and produce a large bass sound. These speakers, by the way, are called ported speakers, because the holes are ports. Because of these ports, these speakers produce a large sound although they are not really big in size. People like large bass and companies sell these speakers for this reason. But some people prefer sealed box speakers that don't have holes. They know that holes can be detrimental to sound quality. You should know more about speakers. So, I'll explain why ported speakers are detrimental in this essay."
3. Usage Issues:
- 'fluto' seems to be a typographical error or misuse of the word. Corrected to 'and produce a large bass sound.'
- 'big' in the context of sound was replaced with 'large' to sound more academic.
- 'company' was corrected to 'companies'.
- 'speaker' was corrected to 'speakers'.
- 'doesn't have' was corrected to 'don't have'.
- 'are bad for' was replaced with 'can be detrimental to' for clarity and academic tone.
- 'ported speaker are bad' was corrected to 'ported speakers are detrimental'.
- Added commas for better sentence flow.
4. Revision:
"While a majority of individuals have a deep appreciation for music, their understanding of the intricacies of speaker technology remains limited. Are you aware that numerous speaker models feature apertures, commonly referred to as ports? These ports, typically circular but occasionally of differing shapes, contribute to a substantial bass output. Such speakers, labeled as ported speakers, are not physically large but are capable of producing powerful sound due to the presence of these ports. There is a significant consumer preference for robust bass output, prompting manufacturers to produce and market these speakers extensively. However, an alternate preference exists for sealed box speakers, which lack the aforementioned ports. Advocates of this design argue that the absence of ports enhances sound quality. It is imperative to expand your knowledge about speakers, and thus, this essay will elucidate the potential drawbacks of ported speakers."
5. Revision Issues:
- Made language more formal and academic.
- Used more sophisticated vocabulary.
- Made sentences more specific, logical, and coherent.
- Replaced 'big sound' and 'big bass' with 'powerful sound' and 'robust bass output' for precision.
- Replaced 'holes' with 'apertures' for precision.
- Introduced the term 'sealed box speakers' more smoothly.
- Reworded the last sentence to make it sound more academic and clear.
6. Comment:
I am impressed with your clear understanding of the subject matter! You have a strong ability to convey complex information in a simple manner, which is a valuable skill in academic writing. I encourage you to keep focusing on your ideas and developing your arguments. Remember to use more formal and academic language, including more specific vocabulary. Your punctuation is quite good, but don't forget

- "about speaker" should be "about speakers"
- "ported speaker are bad" should be "ported speakers are bad"
4. Revision:
Many individuals appreciate music, yet they lack an understanding of speaker design. It might be surprising to learn that numerous speaker systems feature holes, which are generally round, though sometimes they differ. These apertures, colloquially known as 'flutes', contribute to the production of profound bass sounds. Such speakers are commonly referred to as ported speakers, deriving their name from these so-called 'ports'. Despite their modest size, the ports enable these speakers to emit an expansive sound. The allure of profound bass is a driving force behind their marketability, hence the manufacturing companies predominantly focus on this design. However, a segment of the audiophile community prefers sealed box speakers, which lack these ports. They believe that the presence of ports compromises sound quality. To further your understanding of speakers, I will elucidate the disadvantages of ported speakers in this composition.
5. Revision Issues:
- Simplified language and colloquial phrasing have been replaced with more formal academic language.
- More sophisticated sentence structures have been employed.
- Assertions are more carefully qualified and described.
- Greater precision is achieved in description of the speakers and their features.
- A clearer, more concise thesis statement has been provided at the end.
6. Comment:
You've done a great job of organizing your thoughts and presenting them in a clear and logical order. Your knowledge about speakers is impressive, and it's evident that you're passionate about the topic. Your ability to convey the basic information about speakers and their differences is good. For further improvements, work on your vocabulary to express your ideas more effectively and precisely. Also, pay more attention to grammatical structures and consistency in terms. Keep writing, and remember, practice makes perfect!

You should learn more about speakers, so I'll explain why ported speakers are bad in this essay.

- "sealed box speakers that doesn't have holes" should be changed to "sealed box speakers that do not have holes."
- "You should know more about speaker" should be changed to "You should learn more about speakers."
4. Revision:
Many people love music, but they may not be knowledgeable about speakers. Did you know that many speakers have holes? These holes are usually round, although sometimes they can have different shapes. They are like big flutes that produce a powerful bass sound. These types of speakers are called ported speakers because the holes act as ports. Despite their relatively small size, ported speakers are capable of delivering a substantial sound. People are drawn to the deep bass produced by these speakers, which is why companies market and sell them. However, there are also individuals who prefer sealed box speakers that do not feature any holes. They understand that holes can have a negative impact on sound quality. It is important for you to expand your knowledge about speakers, so in this essay, I will explain why ported speakers are considered disadvantageous.
5. Revision Issues:
- The sentence "Do you know that many speakers have holes?" could be rephrased to sound more formal.
- The phrase "big flutes" could be further described to provide more clarity and precision.
- The sentence "These types of speakers are called ported speakers because the holes act as ports" could be rephrased for better flow and coherence.
- The phrase "delivering a substantial sound" could be revised to sound more academic.
- The sentence "People are drawn to the deep bass produced by these speakers, which is why companies market and sell them" could be expanded to provide more explanation and support for the statement.
- The sentence "It is important for you to expand your knowledge about speakers, so in this essay, I will explain why ported speakers are considered disadvantageous" could be rephrased to sound more encouraging and motivating.
6. Comment:
Great job on discussing the topic of speakers and their different types. You have a good understanding of the concept of ported speakers and their appeal to people who enjoy big bass. In order to improve your academic writing, focus on using more specific and precise language. Additionally, work on expanding your ideas and providing more detailed explanations to support your arguments. Keep up the good work and continue to develop your skills as a writer of academic English!

Because of ports, these speakers make big sounds although they are not really big in size. People like big bass and companies sell these speakers for this reason. But some people like sealed box speakers that do not have holes. They know holes are bad for sound. You should know more about speakers. So I will explain why ported speakers are bad in this essay.
3. Usage Issues:
- fluto -> flutes
- sound -> sounds
- company -> companies
- speaker -> speakers
- doesn't -> do not
- I'll -> I will
4. Revision: Many people enjoy listening to music, but they have little knowledge of how speakers work. Speakers are devices that produce sound waves by vibrating air molecules. Some speakers have openings in their enclosures that allow air to flow in and out. These openings are usually circular, but they can also have different shapes. They create low-frequency sounds that enhance the bass effect. These speakers are known as ported speakers, because the openings are called ports. Ported speakers can produce loud sounds even if they are relatively small in size. This appeals to many consumers who prefer strong bass effects, and thus many manufacturers produce and market these speakers. However, not everyone likes ported speakers; some people prefer sealed box speakers that have no openings in their enclosures. They believe that openings degrade the quality of sound by creating distortion and noise. In this essay, I will argue that ported speakers are inferior to sealed box speakers and explain the reasons behind this claim.
5. Revision Issues:
- Replaced "love music" with "enjoy listening to music" to avoid informal language and vague expression.
- Added "they have little knowledge of how" to avoid using "anything" which is too general.
- Replaced "Do you know that" with "Speakers are devices that" to avoid rhetorical questions and provide a clear definition of the topic.
- Replaced "holes" with "openings" to avoid informal language and use a more precise term.
- Added "in their enclosures that allow air to flow in and out" to provide more details and explanation of the function of openings.
- Added "They create low-frequency sounds that enhance the bass effect" to explain the purpose and effect of openings.
- Replaced "by the way" with "These speakers are known as" to avoid informal language and use a more formal transition.
- Replaced "because holes are ports" with "because the openings are called ports" to avoid repetition and use a more precise term.
- Replaced "Because of ports" with "Ported speakers can" to avoid starting a sentence with a conjunction and use an active voice.
- Replaced "big sound" with "loud sounds" to avoid informal language and use a more specific adjective.
- Added "even if" to show contrast and emphasize the point.
- Replaced "People like big bass and companies sell these speakers for this reason" with "This appeals to many consumers who prefer strong bass effects, and thus many manufacturers produce and market these speakers" to avoid informal language and vague expressions, and use more precise terms and logical connectors.
- Added "However," to show contrast and introduce the opposing view.
- Replaced "like" with "prefer" to use a more formal verb.
- Added "that have no openings in their enclosures" to provide more details and explanation of the feature of sealed box speakers.
- Replaced "They know holes are bad for sound" with "They believe that openings degrade the quality of sound by creating distortion and noise" to avoid informal language and vague expressions, and use more precise terms and evidence.
- Replaced "You should know more about speakers" with "In this essay, I will argue that" to avoid using imperative sentences and provide a clear thesis statement.
- Added "and explain the reasons behind this claim" to provide a preview of the main points of the essay.
