请大家帮忙 说下讲解 不胜感激

Answer 1

上面大家都对了。
1.b
what we can（do）（这里do被省略是因为前面主句中有do了，所以这里一定要省略）是主句中do的宾语，to study English well this term是我们要做我们应该尽力而为的目的状语，这类句子都可以把状语提前：
To study English well this term, we will do what we can.
再如：
He did all he could to help me=To help me, he did all he could.

2.句型：keep sth+形容词，使......保持某种状态，keep是动词，sth是宾语，形容词是宾语补足语
keep the door open, keep the room clean and tidy等等

1 B 不定式表目的
2 B open本身可作形容词，表示“打开着”这么一个状态。
第一题选B to表示目的 do 和be显然不能在一起混用
第二题选b open是形容词 keep这做系动词 保持 后跟形容词做表语
