suddenly仅作副词,容易排除; while引导的从句中的谓语动词须是持续性或状态性动词; once含有条件意味; the moment可作连词用,意为“一……就”。

根据答语语意,"我一见到她就把钱还她了"，故最佳选项为B。

)。

2.You should try to keep sitting up late at night.（改错）
Key : keep 后加from 。

4. 课文原句：They didn’t seem to hear me “ No, thank you “ in my poor spoken Chinese.

Sometimes distant objects like hills and tall trees seem to be clear and near. 有些时候，远处的东西像山和小树看起来很近很近的。

The first time I met Tom, he seemed to be sensitive to everything 我第一次遇见汤姆时，他似乎对什么东西都过敏。

2. She ________ to have a lot of friends.
A. seemed
B. appear
C. looked
D. looked like
解析：本题考查动词与不定式短语的搭配。

答案为A。

”seem 和appear 后都可接不定式短语。

但B项时态不对。

look 后只能用to be 这样的不定式；look like 后接名词。
