 英语语法点:英语条件状语从句及用法


  引导条件状语从句的从属连词有if, unless (=if…not如果不……,除非), as/so long as(只要), while(=as long as只要), supposing (that)/provided /providing (that)(假如), in case(假使), on condition that(在……的条件下)等。如:
  You can learn anything so long as you set your mind to learn it. 用心学本领,总能学到手。
  I will go there tomorrow unless it rains.(=…if it doesn’t rain)除非下雨,否则我明天要去那儿。
  He will do the work providing you pay him. 如果你能付费,他可以做这工作。
  In case l forget,please remind me about it. 如果我忘了,请提醒我。
  We’ll let you use the room on condition that you keep it clean and tidy. 我们可以让你使用这个房间,条件是你把它保持整洁。
  注:条件状语从句和时间状语从句一样,从句的谓语动词不能用一般将来时态、过去将来时态或将来完成时,而要用相应的一般现在时、一般过去时和现在完成时态来替代。又如:
  Tell me in case you get into difficulty 1. 遇到困难请告诉我。
  Supposing he does not come, shall we go without him? 如果他不来,是不是不带他去?
  但若从句谓语用了will或would,那will或would则是表示“愿意”的情态动词。如:
  If you will go with me, I’ll wait for you. 如果你愿意等我,我们就帮你做这事儿。

1 difficulty
n.困难,费劲;难事,难题;麻烦,困境
  • If there is any difficulty,please let us know promptly.倘有困难,请迅速通知我们。
  • A little difficulty like this is nothing to us.这点困难算不了什么。
