【答案與解析】

1. 選B，should 后接動詞完成式表示“本來應(yīng)該做某事，結(jié)果未做”，此處含有責(zé)備之意。

2. 選B，對過去情況的肯定推測，宜用“情態(tài)動詞 + 動詞完成式”，再根據(jù)句意，可確定答案為B。注：can 表示推測通常不用于肯定陳述句。

3. 選B，表示過去可能發(fā)生而實(shí)際上未發(fā)生的事，用might + 動詞完成式。若只是推測過去可能已經(jīng)發(fā)生的事，則可用  may [might] + 動詞完成式，如 He may [might] have gone. 他可能已經(jīng)走了。

4. 選C。由句意可知。

5. 選B，do all one can 意為“盡力”或“竭盡全力”。

6. 選C，mustn’t 在此相當(dāng)于 can’t，且語氣更強(qiáng)。

7. 選B，“needn’t + 動詞完成式”的意思是：本來不必做某事，但實(shí)際上做了。上句意思是“你本來不必告訴他這個消息的，因?yàn)樗?/FONT>(當(dāng)時)已經(jīng)知道了”。注意，句中 knew 為過去式。
