答案是D
3

Answer 4

1、B。on介词短语，可以表示一…就…，这里it与observe是动宾关系，应用被动语态。

3、D。主句的谓语是were fully convinced，表示很肯定，所以用only。另外，其中有一个now，而谓语用were，表示这是虚拟语气，所以选D。

7、A。I shall 与you will 是一样的用法，表示将会…。现在进行时表将来，含有计划、打算、准备的意思。

Answer 5

1 D It 与 her 是被动关系啊，大体意思是，她一被发现，It就跑了
2 B 3 D 4 D 5 A 6 B 7 A 8 A 9 A

Answer 6

1.A . It 是这句的主语，它看到HER， 所以要用主动式。
2.A. except 后面接句子。
