Question

Accepted Answer

38. C. This math exercise is so difficult that I can't do it.

39. A. He was chatting with his friends while his teacher was teaching the lesson.

40. D. The darker it became, the colder I felt.

I. 
1. The correct answer is A. writes: raɪts. The pronunciation of the underlined part of "writes" is /raɪts/ (single syllable), which is different from the pronunciation of the underlined parts of "benches" (/ʧɪz/), "cases" (/sɪz/), and "watches" (/ʧɪz/), all of which have the /ɪz/ or /sɪz/ ending.

2. The correct answer is B. collect: kəˈlɛkt. The pronunciation of the underlined part of "collect" is /kəˈlɛkt/ (the stress falls on the second syllable), which is different from the pronunciation of the underlined parts of "concern" (/kənˈsərn/, the stress falls on the second syllable but the prefix is /kən/), "combine" (/ˈkɑmbaɪn/, the stress falls on the first syllable), and "concert" (/ˈkɑnsərt/, the stress falls on the first syllable).

To answer the questions, I will analyze the stress position of each word in the given groups.

**Question 3**
Analyze:
'bicycle' stressed at first syllable
'engineer' stressed at first syllable
'vehicle' stressed at first syllable
'benefit' stressed at first syllable
All words in this group have their main stress position at the first syllable. However, 'engineer' can be a bit tricky. While its primary stress is indeed at the first syllable, a secondary stress often occurs on the third syllable (en-gi-neer). Despite this secondary stress, the primary stress position of 'engineer' still aligns with the other options.

To answer this question accurately, we would need more information about the intended meaning or the specific dialect of English being used. However, based on the provided information alone, we can't definitively conclude that one word's stress pattern is distinct from the others.

But if I must choose an answer:
Answer: B. engineer

5. C. Being on time 
6. B. impressive

7. B. behaving badly

8. A. very busy

Here are the answers to the given sentences:

9. D. adventurer
10. A. underwater
11. C. attraction
12. B. contribution
13. A. Can we do a project on the Shilin stone Forest?
14. D. Certainly. You're welcome!
15. A. when
16. B. where
17. to
