Question

7．我們要保護(hù)環(huán)境，讓它不受到污染．
We shouldprotect our environmentfrom pollution．

Answer 1

分析 protect from．

解答 答案：protect from．這里是說(shuō)保護(hù)…不受傷害，用protect  sb/sth from…，后加名詞代詞或者動(dòng)名詞，這里前面有情態(tài)動(dòng)詞should，后加動(dòng)詞原形，故答案是protect from．

點(diǎn)評(píng) protect …from sth．（保護(hù)）使…免于=protect…against doing 防御
prevent …from doing sth．阻止（防御）…做…=stop sb from doing 阻止…做…
