今天小编为大家分享的主题是雅思写作有哪些句型呢？为了说明或论证某个事物，我们往往需要将其与他物进行比较，由此可能产生难以理解的长句。用来比较的句型包括：... than ...; as ... as; not so much ... as...; while ...，等。在这种句子中，我们只要明确比较了什么，比较是为了说明什么道理，即可抓住主干，理解整个句子的意义。

句子1

For those women who learnt to read through the campaign, the infant mortality rate was 84 per thousand, an impressive 21 points lower than for those women who were still illiterate.

译文：

而那些在这场运动中学会阅读的女性，其婴儿死亡率为84/1000,比仍然不识字的母亲的婴儿死亡率整整低了 21点。

分析：

本句主干为“the infant mortality rate was 84 per thousand”，被置前的一个状语For those women who learnt to read through the campaign遮蔽，后面的 “ an impressive 21 points lower than for those women who were still illiterate ”，与the infant mortality rate was 84 per thousand进行对比，即，将会读书的母亲的婴儿死亡率与不会读书的母亲的婴儿死亡率进行比较。本句的骨干部分：For those …, the infant mortality rate was 84 per thousand, an impressive 21 points lower than …。 从语法上讲，本句an impressive 21 points lower than...之前省略了which was。

原题重现：（True/False/Not Given）

The women who had learnt to read through the National Literacy Crusade showed the greatest change in infant mortality levels.

[参考答案] NG。这里仅比较了学会识字的母亲与没学会识字的母亲，没有提及其他，因此尚不知道到底是不是“变化的”，也许是，也许不是，因此答案是NG。

句子2

Victimized pupils are more likely to experience difficulties with interpersonal relationships as adults, while children who persistently bully are more likely to grow up to be physically violent, and convicted of anti-social offences.

译文：

受到欺凌的小学生成年后更容易在人际沟通中遭遇困难，而那些经常实施欺凌的孩子长大后更有可能具有身体上的暴力倾向并且犯下反社会的罪行。

分析：

本句主干为“Victimized pupils are more likely to experience difficulties with interpersonal relationships as adults”，后面while引导的从句与其进行对比。While引导的从句中，who引导的定语本句修饰children。句子的骨干部分：Victimized pupils are more likely to experience difficulties with interpersonal relationships as adults, while children who … are more likely to …。

原题重现：

Children who are bullied ________

A are twice as likely to commit suicide as the average person.

B find it more difficult to relate to adults.

C are less likely to be violent in later life.

D may have difficulty forming relationships in later life.

[参考答案] D。这个选项是对原文experience difficulties with interpersonal relationships as adults的同义表述。

句子3

The higher the children's IQ scores, especially over IQ 130, the better the quality of their educational backup, measured in terms of reported verbal interactions with parents, number of books and activities in their home etc.

译文：

尤其是在智商超过130的孩子中，他们的智商越高，他们的教育背景的质量越好，这些教育背景包括孩子跟父母的口头交流以及家中书和活动的数量等。

分析：

本句比较智商与家庭教育背景，measured为过去分词做定语，修饰educational backup。本句的骨干部分：The higher the children's IQ scores, …, the better the quality of their educational backup, measured in terms of …, …and …。

原题重现：（True/False/Not Given）

The very gifted child benefits from appropriate support from close relatives.

[参考答案] T。原文通过the higher...the better句式，表达了孩子智商与家庭教育背景之间有正相关的关系。

写作范文中的使用实例

3. Some students may be good at their academic subjects, while others may excel in music, sports, designing, to mention only a few. As each student is unique in his/her own way, to sort out a few and label them as “top students” is senseless and misleading.  （2017/6/24，政府只应该资助学生吗？）

有些学生可能精于学业，另外一些可能在音乐、体育、设计等方面超过别人。由于每个学生都以自己的方式而独特，那么选出一些并标之以“学生”就是没有意义而且具有误导性的。
