Question

1.Such difficult experiments ___ you did that day need much

Answer 1

1.选B.such as是固定搭配.as well as的第二个as是介词,其后可跟宾语（imagination）.

2.选C.考查反意疑问句的用法.句中must表推测,所以变反意疑问句时应该根据must其后的动词,而不是must本身.由于主语是第三人称单数,所以用hasn't.

3.选C.现在分词作宾补.时间状语all the day暗示用doing更好.

4.选C.过去分词短语作定语.考查了几个介词的区分.“系在……”应该用介词to.

5.选A.go against:与……相违背.

6.选B.A和C都是及物动词,排除.B项表示“以平局结束”,更符合题意.
