New Practical College English 新编大学实用英语教程 Unit 5 5）虚拟条件句的倒装 在书面语中，虚拟条件句部分如果含有were, should, 或had，可将if 省略，再把were, should 或had 移到从句句首，实行倒装。如： Should it rain, the crops would be saved. 如果下雨，庄稼就有救了。 =If it should rain, the crops would be saved. Had you come earlier, you would have caught the bus. 如果你早点儿来，你就能赶上那班车了。 =If you had come earlier, you would have caught the bus. Were you in my position, what would you do? 如果你处在我的地位，你会怎么办？ =If you were in my position, what would you do?

We wish we would succeed.(We know we can hardly succeed.) New Practical College English 新编大学实用英语教程 Unit 5 Activity Choose the best answer to complete each sentence. 1. You are late.
