1.I'm not sure if I'll type my paper myself;I have more important hings to do than _____.A.it B.those C.that D.others(选C,A为什么不可以)2.Oh,it's so cold in here.Somebody _____ the window,please.A.closes B.close C.shall close D.will close(选B
1.在比较级中that 指代前面的一句话,而it只能指代一个名词或代词.
2.something 一般情况下要用单数,但是本句正如你所说为祈使句,所以要用复数形式.

1. that指代上文提到的事，this表示下文将要提到的事。这时通常不用it。
2. 你说对了，祈使句。

that 在这里是指代，it没有这个用法
第二句是祈使句
