1. 考查名词性从句的语序
Someone is ringing the doorbell. Go and see ________. (上海卷)< ________.>
A. who is he            B. who he is           C. who is it           D. who it is
解析：本句中用 it 指代“来访者”，只有选项 D 为陈述语序，且符合语境。故最佳答案为 D。

2. 考查名词性从句中的时态—I hear Jane has gone to the Holy Island for her holiday.—Oh, how nice! Do you know when she ________? (湖南卷)
A. was leaving          B. had left              C. has left         D. left
解析：第 1 句中的 has gone 表示 Jane 已去度假，“离开”是一个过去的动作，宾语从句中要用一般过去时态。故最佳答案为 D。

3. 考查名词性从句中连接代词、连接副词的选择After Yang Liwei succeeded in circling the earth, _______ our astronauts desire to do is walk in space. (上海卷)
A. where                  B. what                  C. that                 D. how
解析：因主语从句 our astronauts desire to do 中缺少 do 的宾语，空白处应补充连接代词 what。故最佳答案为 B。
You are saying that everyone should be equal, and this is _______ I disagree. (河南卷)
A. why                    B. where                C. what            D. how
解析：disagree 为不及物动词，因此表语从句中只能用补充作状语的连接副词，选 where，意为“这就是我与你有分歧的地方”。故最佳答案为 B。

4. 考查it在名词性从句中作形式主语和形式宾语Don’t ______ that all those who get good grades in the entrance examination will prove to be most successful. (上海卷)
A. take this for granted                   B. take as granted C. take that for granted                   D. take it for granted
解析：句型 take it for granted that… 意为“认为……是理所当然的”，it是形式宾语，代替后面的 that 宾语从句。故最佳答案为 D。
