英语选择题1 选什么 为什么

W ithout the sun,none of the living things on earth ( ).
a existed b would exist c would have been existed d exists

Answer 1

虚拟语气,
虚拟语气在含蓄条件句中的用法
(1) 条件暗含在短语中。如：
Without your help, we wouldn’t have achieved so much.
没有你的帮助，我们不可能取得这么大的成绩。
（暗含条件是介词短语without your help）
But for your help, I would not have succeeded in the experiment.
如果没有你的帮助，我的实验就不会成功。（暗含条件是but for your help）
It would cause great trouble not to lubricate the bearing immediately.
不立即润滑轴承就会引起很大的故障。
（暗含条件是not to lubricate the bearing immediately）
Alone, she would have been terrified.

与现在事实相反 If I (we,you,he,they)+ 动词过去式(be的过去式用were) I(we) should.You would. He would .They would+动词原形
与过去事实相反 If I (we,you,he,they)+had+过去分词 I(we) should.You would.He would .They would +have+动词过去分词
与将来事实可能相反 If I (we,you,he,they)+ 动词过去式(be的过去式用were)/were to/should I(we) should.You would. He would .They would +动词原形
