雅思听力考试中有一些常见的连接词，很多备考同学认为这些是常规词汇不表达具体语义所以常常忽略，但实质上，这些词是应引起的，尤其条件词就是需要被特别关注的一类词汇，因为这类词往往意味着转折，反义等意义，而这些意义则会是听力过程中很大的变数。接下来就跟小编一起来盘点一下那些容易忽略的条件词吧!
　　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, I’d 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(别的概不接受)。
　　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, I’d say every quarter of an hour, as long as they don‘t last for 10 minutes each time.
　　答案不是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。
　　例四：热带雨林危险吗?
　　There’s no need to be nervous of the rainforest, provided that you treat it with respect and common sense. Most of the animals and wildlife are gentle and harmless.
