Answer 1

1. B
which引导非限制性定语从句，代替整个主句He believes in himself，在从句___ is of...中充当主语。
in my opinion是该非限制性定语从句的插入语，可以忽略。
that不能用于引导非限制性定语从句，what根本都不能引导定语从句，排除；
as虽然也有此种用法，但是它一般翻译为“正如/就像...一样”，且用于被动句式较多，此处不如which准确。

2. C
同样是非限制性定语从句，且该从句采用了倒装语法。
即：where lives my uncle = in which lives my uncle = in Shanghai lives my uncle = my uncle lives in Shanghai
该定语从句缺少地点状语，只能使用关系副词where

3. A
此题考查强调句型和主语从句。
该句正常写法是：(That he often fails in exams) makes his parents worried about him.
该句的主语是一个主语从句，因为该从句不缺少成分，所以用that引导，但是that不能省略。
如果对该句的主语（从句）进行强调，即使用强调句型结构（It is/was + 被强调部分 + that + 句子未被强调部分）时，则直接变为：
It is + 被强调部分（that he often fails in exams）+ that + 句子未被强调部分（makes his parents worried about him）.
这就是答案A。

Answer 3

1.in my opinion 是插入语，可以省略不看，句子就变成He believes in himself,___is of the most importance.非限制性定语从句关系代词用which.
2.如果选which，后面的那个句子就是my uncle lives shanghai，少介词，where=in which，所以填where。where、when等关系副词都等于介词加which 。
3.that he often fails in exams makes his parents worried about him是主语从句。it is that是强调句型，固定句型
