解析
表语从句是跟在系动词（如be, seem, look等）之后，说明主语身份、状态或原因的从句。其核心特征是从句直接跟在系动词后，构成主系表结构。
关键判断点：
- 系动词的存在（如
is,are,was等）； - 从句功能是否解释主语（如说明主语“是什么”“为什么”“在哪里”等）。
常见引导词：that,what,who,where,why,how等。
选项分析
A. That's just what I want.
- 结构拆分：
That（主语）+is（系动词）+what I want（表语从句）。 - 功能：
what I want说明主语That的内容，属于表语从句。
B. This is where our problem lies.
- 结构拆分：
This（主语）+is（系动词）+where our problem lies（表语从句）。 - 功能：
where our problem lies说明主语This的位置，属于表语从句。
C. That is why he didn't come to the meeting.
- 结构拆分：
That（主语）+is（系动词）+why he didn't come（表语从句）。 - 功能：
why he didn't come说明主语That的原因，属于表语从句。
D. Whether he can come to the party on time depends on the traffic.
- 结构拆分：
Whether he can come（主语从句）+depends（谓语）+on the traffic（宾语）。 - 功能：
Whether he can come作为主语，属于主语从句，而非表语从句。
