48．We believe ________ you have been devoted to ________ naturally of great necessity.

A. that; being

B. all that; be

【答案】 D

【解析】【分析】句意：我们相信你所投入的当然是非常必要的。分析句子可知，believe 后接宾语从句，宾语从句中you have been devoted to缺少宾语，表示事物故用what；what you have been devoted to为主语，从句作主语，谓语动词用单数，故选D。

【点评】考查名词性从句和主谓一致，本题涉及what引导的主语从句和一般现在时。

49． ---- Let's send him home. Do you know _________?

【答案】 B

【解析】【分析】句意:----让我们把他送回家。你知道他住在哪里吗?----我不知道。宾语从句就是一个句子作动词或介词的宾语。宾语从句由特殊疑问句变来就用原来的疑问词作引导。在宾语从句中只能使用陈述句语序，不能用疑问句语序。所以选B。

50．I know he's been curious about everything, but that's . Be patient!

A. what do kids like

B. what kids like

C. what are kids like

D. what kids are like

【答案】 D

【解析】【分析】句意:我知道他对一切充满好奇，但那是小孩的样子。耐心点儿。That's 后跟的是一个表语从句，从句要用陈述句语序，所以A,C错了B. what kids like那是孩子喜欢的东西，D. what kids are like那是小孩的样子.对一切充满好奇是小孩的行为，故选 D like，动词，表示喜欢，有时态变化形式;be like表示像，like是介词，like没有词形变化。这是中考的常考点。
