又如：W:Did you see film last night? M:I wouldn’t have gone to see it if I’d known it was boring. Q:Where was the man last night? A) In a bar. B) In a cinema. C) At a lecture. D) Unreasonable. 应选 B)
条件句中以if引导居多，注意这种句式的表达特点。
它们经常用省略的形式，如if possible,if any,if not,if so,if necessary,if needed等 ，听省略形式的条件句，主要应该抓住主句的基本内容，因为条件句不易听错，只要抓住了主句的基本内容，就能正确做题。此外，表示条件的连词，除了if外，还有as long as,so long as,suppose,supposing,let’s say等。
(九)判断比较句式
比较有两种基本形式，相等比较和不等比较。相等比较的基本句型为：主语 谓语 as 形容词或副词原级 as 被比较对象。请看下面一句话的比较：Walking fast uses up as many calories as running slowly.其中被比较对象为running slowly.但要注意有时出现的一句 话只是形式上的相等比较，但在含义上却是不等比较。像almost,nearly,practically通常表示还差一点，不及等。不等比较的基本句型为：主语 谓语 比较级 than 被比较对象。此外，以比较级形式可表达最高级含义。如下面一句话： No other student studies as hard as peter.因此，应是彼特学习最刻苦。
下列是一些常见的比较句式：as … as …,the same as,比较级 than,prefer … to …,would rather … than等。
在比较对象上，注意that、one的指代；此外，还有句子成分的省略。 下面是一个例子： W:I think I’ll wear my red dress to the party tonight. M:Can’t you wear your blue one? I like it much better. Q:How does the man feel about the woman’s red dress?
A) He hates it. B) He likes it better than the blue dress. C) He doesn’t know which dress she means. D) He doesn’t like it as well as the blue one. 应选D)。
