选择什么,不选什么说出理由,麻烦把相关知识告诉我.谢谢
參考答案:1.A
Anything后面是个定语从句，从句中缺的是及物动词do的宾语，所以选what.
How只能做状语，排除。 else，what不能引导定于从句，排除。
2. B
逗号后面也是定语从句，局中whom作介词of的宾语，代表model workers.
them不能引导定语从句，排除。that,which不能指人，排除。
3.A
in which相当于where,在factory后面的定语从句里面作状语，表示地点，就是说we students saw ...in the factory.
其它三个答案都不能作地点状语，排除。
4.B
两个逗号中间是个同位语从句，补充解释主语I.
That is语法上成立，但that通常不指人，排除。am只能作系动词，不能充当同位语从句的主语。who am语法不成立，am只和第一人称搭配。
