Answer 1

1.C have no choice but to do 别无选择 live on sth.靠什么什么来维持生命
2.A to 表目的 protect表示保护使之不受破坏 preserve表示保护使之保持原样
3.B it`s no good+doing it`s not good +to do
4.C 时态和非谓的考察，主语是they与动作是主动关系，从句意上理解应该是：项目还没有完成，他们不得不再呆上两个礼拜，所以用完成态,而非谓的否定需要否定整个非谓部分
5.B though是从属连词，前后主语一致时省略主语和be动词，be lacking in/be lack of
6.A bell和“暗示”“打断”都是主动关系

Answer 2

1.C.首先是have no choice but to do 这个结构。
