答案:第一题选什么? 第二题(A,C)选哪个?第三题选哪个?第四题(A,D)选哪个?第五题选哪个?
希望能给出为什么?谢谢了~~

1.A it's time that后面跟虚拟语气,用过去时。

2. A 这里是很特殊的than句子的倒装。因为前半句主语是nebraska,不是it,所以BCD都不能选。

3. D 因为第一句里是have got to,所以不能用C,C里面是do。

4. D 独立主格。如果用A,前后主语不一致。

5. B 倒装句。

想要说明得再详细一点请在线联系我。

D、C、C、A、D

1B get down to表示去做
2C
3D 乍一看C也可以。但是C的动词形式不对,应该是so have i
4B 如果前面是分词引导的,则分词主语得和后半句主语一致,而后半句主语是车,所以前半句三个以人或钥匙为主语的选项就不对。应该是那个不用分词形式的B
5B
