TOEFL Writingで表現を覚えるときの注意点

TOEFL Writingで使える表現を覚えることは大切です。

しかし、テンプレートをそのまま丸暗記して、どの問題にも同じように使うのはおすすめしません。

理由は、問題に合っていない表現を使うと、不自然な回答になりやすいからです。

例えば、どの問題でも、

I strongly agree with this statement.

から始めると、質問によっては合わないことがあります。

Academic Discussionでは、教授の質問に対して、自分の意見を自然に投稿する必要があります。

そのため、表現は「そのまま貼り付けるもの」ではなく、「考えを整理するための道具」として使うのがよいです。

TOEFL Writingでまず覚えたい基本構成

Academic Discussionでは、次の流れで書くと分かりやすいです。

1. 自分の意見を示す
2. 理由を説明する
3. 具体例を出す
4. 必要なら他の学生の意見に触れる
5. まとめる

たとえば、次のような流れです。

I agree that universities should offer more online courses. One reason is that online classes give students more flexibility. For example, students who work part-time can watch recorded lectures after work. This makes higher education more accessible to different types of learners.

この回答では、

• 意見：online coursesに賛成
• 理由：柔軟性がある
• 具体例：アルバイト後に録画授業を見られる
• まとめ：多様な学生が教育を受けやすくなる

という流れになっています。

表現を覚えるときも、この流れに沿って整理すると使いやすくなります。

意見を示す表現

Academic Discussionでは、最初に自分の立場を明確にすることが大切です。

使いやすい表現は次の通りです。

賛成するとき

• I agree with the idea that ...
• I support the view that ...
• I believe that ...
• I think that ...
• I agree with [Student A] that ...

例文：

I agree with the idea that universities should require students to take public speaking classes.

I support the view that online learning should be offered as an option for students.

I agree with Maria that students need more opportunities to develop practical skills.

例文：

I disagree with David because face-to-face discussions can help students develop communication skills.

一部賛成するとき

• I agree with this view to some extent.
• While I understand this opinion, I believe that ...
• Although this idea has some benefits, I think ...
• I can see both sides, but I believe that ...

例文：

I partly agree with this idea because online learning is convenient, but I still think in-person classes are important.

While I understand Student A’s point, I believe that universities should not replace all classroom learning with online courses.

I can see both sides, but I believe that public speaking classes should be optional rather than required.

理由を述べる表現

自分の意見を書いたら、次に理由を説明します。

Academic Discussionでは、理由をたくさん入れるより、1つの理由を分かりやすく説明する方が安定します。

基本表現

• One reason is that ...
• This is because ...
• The main reason is that ...
• A key reason is that ...
• This can be explained by ...
• The main benefit is that ...
• One possible concern is that ...

例文：

One reason is that online classes give students more control over their schedules.

This is because many students have part-time jobs or family responsibilities.

The main benefit is that students can review recorded lectures whenever they need to.

A key reason is that public speaking skills are useful in many professional situations.

理由を具体化する表現

• This means that ...
• In other words, ...
• As a result, ...
• This allows students to ...
• This helps students ...
• This can make it easier for students to ...

例文：

This means that students can study at a time that fits their personal schedule.

In other words, online learning can make education more flexible.

This allows students to balance their studies with work or family responsibilities.

This can make it easier for students to continue their education even if they live far from campus.

具体例を出す表現

TOEFL Academic Discussionでは、具体例があると回答に説得力が出ます。

理由だけで終わると、内容が浅く見えることがあります。

基本表現

• For example, ...
• For instance, ...
• A good example of this is ...
• This can be seen when ...
• In my experience, ...
• For example, a student who ...
• For instance, people who ...

例文：

For example, a student who works part-time can watch recorded lectures in the evening.

For instance, students who are shy may become more confident if they practice speaking in a supportive class.

A good example of this is group projects, where students need to explain their ideas clearly.

This can be seen when students use online tools to review difficult lectures before exams.

In my experience, students often learn more effectively when they can discuss ideas with classmates.

具体例を作るときのコツ

具体例は、必ずしも実体験である必要はありません。

一般的にありそうな例でも、理由を支えていれば使えます。

例えば、

Public speaking classes are useful.

だけでは弱いです。

次のように具体例を入れると、分かりやすくなります。

Public speaking classes are useful because many jobs require employees to explain their ideas clearly. For example, a new employee may need to present a project plan in a meeting or answer questions from clients.

このように、場面を具体化すると説得力が上がります。

他の学生の意見に触れる表現

Academic Discussionでは、他の学生の意見に自然に触れると、ディスカッションらしい回答になります。

ただし、他の学生の意見を長く要約しすぎる必要はありません。

短く触れて、自分の意見につなげるのがポイントです。

賛成してつなげる表現

• I agree with [Student A] that ...
• [Student A] makes a good point about ...
• I think [Student A] is right that ...
• Building on [Student A]’s idea, I would add that ...
• I share [Student A]’s view that ...

例文：

I agree with Anna that online learning can be convenient for students with busy schedules.

David makes a good point about the importance of face-to-face communication.

Building on Maria’s idea, I would add that practical skills can also help students outside the classroom.

反対してつなげる表現

• I understand [Student B]’s point, but I think ...
• While [Student B] makes a valid point, I believe that ...
• I see why [Student B] thinks this, but ...
• I disagree with [Student B] because ...
• Although [Student B] is concerned about ..., I think ...

例文：

I understand David’s point that online classes can reduce interaction, but I think this problem can be reduced through live discussions and group projects.

While Maria makes a valid point about stress, I believe that public speaking classes can help students build confidence gradually.

I disagree with Anna because AI tools should support learning, not replace students’ own thinking.

他の学生に触れるときの注意点

他の学生の意見を長くまとめすぎると、自分の意見を書く時間が減ります。

悪い例：

Anna says that online learning is convenient because students can study at home. David says that online learning is not good because students cannot talk to each other. Anna thinks flexibility is important, and David thinks communication is important.

このように他の学生の要約だけで終わると、自分の意見が弱くなります。

改善例：

I understand David’s concern about reduced interaction, but I believe online learning can still be effective if universities include live discussions and group work.

このように、相手の意見に短く触れて、自分の主張に進む方が自然です。

反論・譲歩に使える表現

Academic Discussionでは、一方的に主張するだけでなく、別の意見を認めたうえで自分の考えを書くと、バランスのよい回答になります。

譲歩する表現

• Although this may be true, ...
• While this is a valid concern, ...
• It is true that ..., but ...
• I understand this concern, but ...
• This may be a problem in some cases, but ...

例文：

Although online learning may reduce face-to-face interaction, it can still be effective if students participate in live discussions.

While this is a valid concern, I think universities can solve it by offering both online and in-person options.

It is true that some students feel nervous when speaking in public, but practice can help them become more confident.

反論する表現

• However, I think ...
• However, this does not mean that ...
• I do not think this is always the case.
• This problem can be reduced if ...
• This concern is understandable, but ...

例文：

However, I think online classes should not completely replace in-person classes.

However, this does not mean that students should avoid public speaking altogether.

This problem can be reduced if professors create supportive environments for discussion.

使いすぎに注意したい表現

howeverやalthoughは便利ですが、使いすぎると文章が重くなります。

短いAcademic Discussionでは、逆接表現を1〜2回使えば十分です。

大切なのは、接続表現をたくさん使うことではなく、文と文の意味が自然につながっていることです。

まとめる表現

最後に、自分の意見を短くまとめます。

Academic Discussionでは、Conclusionのような長い締めは不要です。

1文で十分です。

基本表現

• Therefore, ...
• For this reason, ...
• This is why ...
• Overall, ...
• As a result, ...
• In this way, ...

例文：

Therefore, universities should offer online classes as an additional option.

For this reason, public speaking classes can prepare students for both academic and professional life.

This is why AI tools should be used carefully as a support for learning.

Overall, I believe that practical skills should be taught alongside academic subjects.

As a result, students can become more confident and better prepared for future careers.

まとめで新しい理由を出さない

最後の文で、新しい理由を出す必要はありません。

悪い例：

Therefore, public speaking classes are useful. Also, universities should reduce tuition fees.

このように、最後に新しい話を出すと、まとまりが悪くなります。

まとめでは、本文で書いた主張を短く言い直しましょう。

Write LoopでTOEFL Writingの表現を復習する

TOEFL Writingで使える表現を覚えるには、ただフレーズ集を読むだけでは不十分です。

実際に書いて、添削を受けて、使い方が自然かどうかを確認する必要があります。

Write Loopでは、IELTS / TOEFL Writingの練習、AI添削、弱点分析、復習をまとめて行えます。

TOEFL Writingの表現練習では、次のような流れで使えます。

1. TOEFL Academic Discussionの問題を選ぶ
2. 覚えたい表現を使って英文を書く
3. AI添削で文法・語彙・自然さを確認する
4. 不自然な表現や前置詞ミスを確認する
5. ミスを弱点として記録する

ChatGPTなどで英作文を添削することもできますが、過去のミスを自分で整理したり、よく間違える表現を記録したり、復習問題に変えたりするには手間がかかります。

Write Loopでは、添削結果を学習データとして残し、次の1問に活かせるようにすることを目指しています。

「添削して終わり」ではなく、「書くたびに弱点が見える」状態を作りたい人に向いています。
