Answer 1

1 B
再见到你真高兴,我原来不知道你住在这里
根据意思,现在已经知道了,如果A一般现在时,表示现在还不知道,而B表示过去不知道,既然见了面自然现在就知道了
2 B
首先判断缩写到底是is 还是has,句子中没有其他的谓语动词,所以只能是is,因为has 是助动词,不能构成谓语,需要借助其他的动词构成完成时.确定is,前面用肯定,后面用否定构成反义疑问句.
3A
因为没有hope sb to do这个句型,淘汰B,D
hope to do 或者hope +that 从句可以,that可以省略
all应该放在实义动词前,所以排除C
4 A
since后面使用现在完成时 或者一般过去时,排除BD,
C直接用knew就可以了
