Science and Engineering Context

Exercise Context

In science and engineering, people often:

  • Give opinions about ideas.
  • Say what they like or dislike.
  • Ask questions to learn more.
  • Discuss experiments, machines, and technology.

Grammar 1: Present Simple for Opinions

Use

We use the present simple to give opinions.

Pattern:

Subject + think/believe + statement

Examples:

  • I think this robot is interesting.
  • I believe solar energy is good.
  • She thinks the design is good.

Opinion Expressions

  • I think...
  • I believe...
  • In my opinion...

Grammar 2: Like, Love, Hate, Prefer

Use these verbs to talk about your feelings.

Verb Meaning Example
like positive feeling I like science videos.
love very positive feeling I love robotics.
hate very negative feeling I hate long reports.
prefer choose one thing more I prefer electric cars.

Grammar 3: Can for Asking Questions

Use

Use can to ask for information or help.

Pattern:

Can + subject + base verb ... ?

Examples:

  • Can you explain this idea?
  • Can we test the machine?
  • Can you help me?

Grammar 4: Question Words

Question Word Use Example
What Ask about a thing What is this machine?
Why Ask for a reason Why is it useful?
How Ask about a method How does it work?

Remember:

  • What = thing
  • Why = reason
  • How = method

Worked Example 1

Situation: You see a new robot.

🔑 Đáp án & Giải thích

"I think" được dùng để nêu ý kiến cá nhân. "How does it work?" hỏi cách hoạt động của robot. Đây là câu hỏi dùng từ để hỏi "How".

Worked Example 2

Situation: Two energy sources are discussed.

Sentence: I prefer solar energy.

Question: Why is solar energy important?

Why is it correct?

  • "Prefer" shows a choice.
  • "Why" asks for a reason.
🔑 Đáp án & Giải thích

"Prefer" diễn tả thích một lựa chọn hơn lựa chọn khác. "Why" dùng để hỏi lý do hoặc nguyên nhân.
