A.that am B.who am C.that is D.who

hangzhou is a city___there is a beautiful lake
A.which B.what C.where D.at which

hangzhou is a city___has a beautiful lake
A.which B.where C.in which D.who

Answer 1

B.who am
非限制性定语从句，who指的是I，所以be动词要用am

C.where
先行词city在从句中的成分是状语，如下
there is a beautiful lake in the city
所以用关系副词

A.which
先行词city在从句中的成分是主语
The city has a beautiful lake
所以用关系代词

Answer 2

第一个是who am,要和前面的先行词保持一致
第二是 where，这个是关系副词，你看后面的从句其实不缺少东西的，它就只能放一个关系副词，而不是代词，所以选which和that都是错的
第三个是which,这个是代词，因为后面的从句缺少主语，它等于是少个东西的，你要放个主语
