【答案詳解】

1. B。should 后接動(dòng)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。but you should have asked me first的意思是“你本來應(yīng)該先問我一聲的”。

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

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

4. A。根據(jù)下文的 will be 可知，“他考試不及格”是將來的事，據(jù)此可排除B和D。再根據(jù)語(yǔ)意，排除C。

5. D。從時(shí)間上看，由于是昨天沒來開會(huì)，所以推測(cè)“他生病”也應(yīng)是昨天，故排除A和C。從語(yǔ)境上看，既然上文說I’m not so sure，那么說明說話者對(duì)自己的推測(cè)沒有很大把握，故選D。

6. C。根據(jù)上文的過去時(shí)態(tài)可知，此句談的是過去的事，故排除A和C。根據(jù)語(yǔ)境排除D。You could have helped me的意思是“你本來可以幫幫我的（但你卻沒有幫）”。

7. B。比較：needn’t have done意為“本來不必做某事”，may not have done意為“(過去)可能沒有做某事”，shouldn’t have done意為“本來不應(yīng)該做某事”(must表推測(cè)時(shí)不用于否定式)。根據(jù)句意，顯然只能選B。

8. D。將四個(gè)選項(xiàng)分別置于句中，比較句意的通順性，可知填should最佳。

9. A。Shall I…? 意為“要我……嗎？”，又如：Shall I help you? 要不要我?guī)湍愕拿?/FONT>? Do you want a bath at once, or shall I have mine first? 你馬上洗澡還是我先洗?
