Question 1: A. This competition is for people who can swim over 200 metres.
Question 2: C. School zone - children may be crossing.
To determine the word whose underlined part differs from the other three in pronunciation, let's analyze each question:
Question 3. A. relax B. affect C. connect D. impress
Looking at the IPA notations:
- relax: rɪˈlæks
- affect: əˈfɛkt
- connect: kəˈnɛkt
- impress: ˈɪmprɛs
All words except "impress" have a schwa sound (ə or ɪ) followed by the stress mark (ˈ). "Impress" has a distinct /ɪm/ sound at the beginning and the stress is on the first syllable. However, what sets "impress" apart is that it's the only word that doesn't start with a schwa sound (ə) or have a reduced vowel sound at the beginning like the other three. But, more importantly, the stress pattern is the same, but we can see that the vowel sound in "relax" is different from the others which all contain the "ɛ" sound.
However, considering the answers more carefully, we notice that A. relax is the one that stands out because it has a distinct "æ" sound in "rɪˈlæks". The other options, "affect", "connect", and "impress", all have the "ɛ" sound in their notations.
Question 4. A. waved B. decided C. played D. failed
Looking at the IPA notations:
- waved: weɪvd
- decided: dɪˈsaɪdɪd
- played: pleɪd
- failed: feɪld
All words except "decided" have a diphthong /eɪ/ sound in their notations. "Decided" has a distinct /ɪ/ and /aɪ/ sound, setting it apart from the other three.
However, we can notice that the correct answer can also be A. waved because it has a distinct /weɪ/ sound which doesn't start with /feɪ/ or /pleɪ/ like "played" and "failed".
For question 5, the correct answer is A. Vietnam has a lot of great cultural values that young people should recognize.
For question 6, the correct answer is B. Jack said that they were holding a workshop on designing posters that night.
For question 7, the correct answer is C. Although I tried hard, I couldn't lift the suitcase.
