8. 这个问题你会回答吗

—What made you so worried?

—______

A. Because I lost my wallet.                   

B. As I lost my wallet.

C. Losing my wallet.                               

D. Lost my wallet.

此题应选C。容易误选A。

分析：由于问句中的疑问词what在句中用作主语, 所以其相应的答语也应是能用作主语的成分。答案A, B错误, 因为它们是原因状语; 答案D错误, 因为过去分词不用作主语。

选项C正确, 因为动名词可用作主语。答句其实是一个省略句, 补完整为：Losing my wallet made me so worried. 在回答特殊疑问句时，要特别注意其疑问词的含义以及它在句中的句法功能；反过来, 要是根据答语选择疑问词, 也要注意其对应关系：

1. —_____ does he come to see you?

—Once a week.

A. How long              B. How often             C. How soon             D. How much

2. —How long has he lived here?

—____ he was a child.

9. 是 such...as 还是 such...that

He’s such a good teacher ______ we all love and respect.

A. that                     B. as                        C. who                     D. so

此题应选B。容易误选A。主是是受句子意思的影响以及受 such...that 这一固定句式的影响。
