–Hi, Kate!
--Hi, Mary. I ______ you are here.
A. don’t know B. don’t think C, think D. didn’t know
( )117. –Have you ever traveled abroad?
--Sure. I ______ the language of English in the USA two years after I graduated from the university.
A. used to learn B. was used to studying
C. have studied D. didn’t use to study
( )118. The visitors are very ______ to see so many changes _______ in Shenzhen since 1979.
A. surprise; have been taken place B. surprising, took place
C. surprised, have been taken place D. surprised, have taken place

1.选D。原来没遇见不知道Kate在这里,现在已经知道了,所以过去时。
2。选A,过去发生,曾经学过,use to do something.
3。选D,surprised是惊讶的,surprising是令人惊讶的;take place 是非及物动词词组,不能用被动语态,只能用主动语态。

只对第一题进行补充,对第二题进行扩展(或许是我多事,你可能知道我所说的),楼上的已经近乎完美了!
1)由于宾语从句要求主句从句时态一致,后面是现在时前面只能是现在时了。可是当前面是现在时时,后面可以接需要的任何时态。
2)use to do sth. 过去常常作某事(现在不做了)
be used to doing sth. 习惯于作某事
be used to du sth. (某物)备用于作某事,相当于be used for doing sth.
呵呵!!!~~~

D 过去时,表示刚才不知道
A used to learn 曾经学习过,符合语境
D surprised修饰人 SURPRISING 修饰物 take place没有被动语态
