选择题
It’s not doing the things we like, but liking the things we have to do makes life happy.
A． that
B．which
C．what
D．who
答案
答案：A
题目分析：考查强调句结构用法。强调句型：It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分。本题强调主语not doing the things we like, but liking the things we have to do。句意：是做我们喜欢做的事情，而不是喜欢我们不得不做的事情让生活幸福。故A正确。
【知识拓展】
1. 在强调主语时，that后的谓语动词要与被强调者保持人称和数的一致。
It is I who am a teacher.
2. 在强调not …until 结构中由 until 短语（或从句）表示的时间状语时，要用固定的强调句型It is(was) not until ...that...。
It was not until 12 o'clock last night that my father came home.
3. 特殊疑问句中只有疑问词可以强调，其强调结构是“被强调部分（通常是疑问代词或疑问副词）+ is/was + it + that/ who + 其它部分？
Where was it that you were born?
