cause ①名词,起因、原因

【辨析】cause与reason

区别一

表示造成某一事实或现象的直接原因或起因,常用 cause of结构。如:

Carelessness is often the cause of fires. 疏忽大意往往酿成火灾。

区别二

若是说明或解释某种行为或看法的借口、理由,常用reason for,reason whythat结构。如:You have no reason for complaint. 你没有理由抱怨。

注:表示“理由”时,两者虽然常常互换,但也有区别:

(1) cause 是不可数名词,而 reason 可用作可数或不可数名词,因此当需要用复数或受 a, every, many 等修饰时,通常要用 reason 。如:

I have many reasons to fear him. 我怕他是有很多理由的。

(2) reason 之后可接 why 引导的定语从句,而 cause 不能。如:

The reason (why) I didn’t tell you was that I wanted it to be a surprise. 我没有告诉你,是想让它给你一个惊喜。

②动词,引起,导致

Many accidents are csused by careless driving.

【词组】cause she sth

cause sb/sth to follow sth

Chatting online may cause you much trouble. 网上聊天可能给你带来很多麻烦。

What caused the ship to sink?是什么导致了船的沉没?

【小试牛刀】

A. are caused

B. were caused

C. have caused

解析:选B
