【小站名师】雅思写作审题中遭遇头疼的句子怎么办?

对于本身语法就很薄弱的考生而言，如果上面的讲解还是有些生涩，那么下面我们就为大家补充一些关于条件从句，人称指代，比较事物这三个语法点的必备知识：

条件从句细分有零条件句、第一条件句、第二条件句、第三条件句。

l 零条件句可以表示某事是普遍的真理或事实：If you own a car, you also have to pay for insurance and registration every year. 也可以表示所谈事情不再属实，就用过去时：When I was a child, if I helped my mother, she gave me extra pocket money.

l 第一条件句可以表示某事在将来会有一种可能的结果：If you leave your money in the bank, you won’t earn any interest and it may lose value over time. 如果这种可能性不大，可以用might/could/may来替代will：If I invest it, I might/could/may lose it all. 但如果这种可能性会随着时间变化，可以用can来替代will：If you travel at rush hour, the trains can be very crowded.

l 第二条件句可以表示现在或未来时间中想象的或者不太可能的情况：If I went travelling, I wouldn’t have any money left over.

l 第三条件句可以表示过去时间中想象的但是没有发生的情况：If I’d bought a second-hand car, I wouldn’t have taken out this big bank loan. 如果过去时间中想象时已经知道可能性很小，可以用might/could来替代would：If I’d saved more money, I might have gone on that college trip last week. 最后除了if以外，还有其他引出条件的其他词语。用when/as soon as/as long as，要比if的可能性大：I will give you a lift into town when/as soon as/as long as I finish my work in time. 用provided/providing that，要比if更加口语化：You won’t lose any money provided that you think of it as a long-term investment. 而用In case，可以表示预防：You should keep this reference number in case there are any problems.

代词指代部分考生需要了解一些基本知识还有一些特殊情况。

l 主语代词用在动词前面：I you he she it we they;宾语代词用在动词或介词后面：me you him her it us them;物主代词用在指代物主限定词和名词：mine yours his hers ours theirs;反身代词用在主语和宾语一致或者强调主语和宾语：myself yourself himself herself itself ourselves yourselves themselves。

l 了解完基本知识以后，考生还需要知道一些特殊情况。

首先，It可以作没有实质意义的主语用在句首，这些句子通常关于天气时间和距离：It’s raining/five o’clock/10 km from the sea. It也可以作形式主语用在句首，指代动词不定式和ing形式：It won’t take long to settle in. 其次，you and we可以指代广义上的每个人：In China you/we often eat sandwiches for lunch. 此外，they可以指代专家或权威机构：They have changed the law recently. 最后，one/ones可以避免可数名词重复使用：I do have rules. The most important one is that I want to everyone to feel at home.

考生就比较事物这个语法知识点需要了解一些常见的比较方式。

l 首先题目可以用as+形容词/副词+as表示相同或相似：Older athletes are as likely to achieve their peak fitness as younger athletes. 其次题目还可以用not as many/much +名词表示差异：There aren’t as many people doing sports at school (as there used to be). 最后题目可以用倍数和副词来特定化信息：China won nearly twice/three times as many silver medals as the US.

总而言之，考生在考场遇到这些令人头疼的复杂句时，要沉着冷静、认真仔细地分析句子的语法结构，抓住句子主干和关键信息，从而更好地理解题目意义并有效改写开头段，随后组织出全篇的思路。这些能力都需要考生注重平时积累，细致梳理每一个语法知识点，才能在考场上所向披靡无往而不胜。
