Answer 1

BCC
1.what to do一般连在一起使用，how多与deal with连用或者直接how to pass
2.树是被植，所以用被动语态。Must表推断时比Can更为确切，表示更加肯定
3.remember to do记得去做某事（未做），remember doing sth记得做过某事（已做）
remind可以与of连用，也可以与about连用

Answer 3

1.B 他必须做什么，所以用what；另外宾语从句用陈述句语序
2.D 树被种，所以是被动语态；must在这里更好些
3.C remember to do 表示记得将要做什么；about：关于什么事情

Answer 4

1.B他知道他要做什么去通过考试。what作do的宾语。
2.Cmust必须。树是被植的，用被动be.
3C.remember记得去做某事，用to+动词原形。
