说起雅思听力出现的条件词,先说一句西方的.谚语：There is no free lunch in the world. 世界上没有免费的午餐。很多语句的前后都会伴随着一些条件词：
Only if, Unless, Except for , As long as, Provided that, On condition that
如果听题时候分神了,烤鸭会死得很惨!
例一：只有二三年级生才能使用MAC电脑吗?
The third computer network that is the Macintosh computer network is reserved for the second and third year students to use only, unless you are the first year students of the Graphic Design course, who require higher quality of the output of your work.
不是,因为后面有个unless部分。
例二：是否任何事情都可以联系你?
Q: May I put you into our mailing list?
A: Well, Id prefer not, except for the information about the promotion you mentioned just now.
只有一个条件可以,就是except for后面的情况。
例三：你觉得多长时间播一次广告可以接受呢?
Q: How long will it be tolerate to have adverts?
A: Well, Id say every quarter of an hour, as long as they dont last for 10 minutes each time.
答案绝对不是10分钟,我的课上这个题是重点题也是难题!很多考生会选错,纯粹是因为考生只听到10分钟这个点太清楚了,别的都很模糊,而且as long as 的条件词特别提醒了考生后面的错误选项。
