在雅思写作中，词汇是最基础也是相当重要的，词汇过不了关何谈其他。词汇中有些词是常用且起到的作用也是不可忽视的，然而却没有引起考生足够的重视，比如with和it。今天，前程百利小编为大家简单讲解二者的知识点，跟着小编一起来了解雅思写作之"小词"也能有大大的力量吧。
with：
使用“with”的好处和应该注意的事项：
① 好处：
a. 表顺承意义：伴随、因果、条件等。
b. 不受语法上前后主谓一致的限制。
② 注意事项：
a. “with”后面用名词或动名词
b. “with”结构可以和主句有逻辑关系
it (本文所讲it的用法主要是当做形式主语的情况下)：
(一) 什么是形式主语
作为形式主语的it并无实际语义，是为满足语法上的需要，避免句子头重脚轻，它代替的是句子的逻辑主语。
(二) 形式主语it所在的句型类别
1、作不定式的形式主语
(1) 句型
It is + a pity/a pleasure + to do sth.
It is + wrong/right/wise/cruel/naughty/selfish + of sb. + to do sth.
(2) 雅思范文写作实例
A. Beyond this, it is also of paramount importance to use theaters and museums as the “social classroom” of culture and history education.
B. I think it is by no means pointless, in any way, to try to keep traditions alive with technology. (Cambridge 3, P162, Task 2)
据统计，剑桥官方的雅思真题(剑3—剑8)几乎每一篇Task2考官范文中，都有所使用，甚至在有的文章中出现三次之多。
(3) 学生写作实例
实例1：Many people, if not most, are strong believer in the claim that regard children go to work as completely wrong, while others hold the opposite opinion.
修改建议：it is completely wrong for children to go to work.
实例2：They have to complete their homework conscientiously within limited time and difficult to discover the problems in studies.
修改建议：thus it is difficult to discover their problems in study.
2、作动名词的形式主语
(1) 句型
It is + (no) use/good/useless/a waste of time/energy/efforts + doing sth.
It is + good/useless/hard/foolish/enjoyable/worthwhile + doing sth.
(2) 雅思范文写作实例
A. For instance, children usually pay attention to match their clothing and toys; in fact, it is really worth competing thing that their study is being ignored.
B. Some parents believe that it is no use having second education for their kids.
(3) 学生作文实例
实例：Particular countries and individuals deals with environmental issues are no use.
修改建议：It is no use dealing with environmental issues by particular countries and indivuduals.
3、作主语从句的形式主语
(1) 句型
It is + (adj) n./(adv.) adj./(adv.)v-ed + that……
It + seems/happens/appears/matters//strikes/occurs(突然想起) + that……
(2) 雅思范文实例
A. It is an understandable fact that many employers may prefer to use the services of children simply to save money by paying them less than adults and it is this type of exploitation tht should be discouraged. (Cambridge 3, P164, Task2)
B. Admittedly, it is common sense that a person without cooperative spirit will be difficult to survive in the modern society.
(3) 学生写作实例
实例1：It is quite obvious/evident/apparent that the quantity of families whotends to go outside and infuse fresh oxygen into their lungs is growing steadily.
实例2：It is universally acknowledged that the best way to arouse people’slove to our nature, who has devoted herself too much to human being’s development while has received barely anything till now, is to let them see the beauty of hers by themselves.
(三) it作形式主语的特征分析
根据以上对it作形式主语的句型结构的解析，对雅思写作范文、尤其是官方考官范文的分析，以及对学生写作过程中出现的it使用状况的详细解读可知：相比较于名词性从句、定语从句、状语从句的复杂性和多边性，it作为形式主语的句式结构可谓简明扼要，学生掌握起来应该说是得心应手的。
(四) 不能正确使用it形式主语的原因
在信息编排时，英语句子遵循“end focus”的原则，即旧信息在前，新信息在后“old information+new information”; 但是，当句子主语结构较长，容易使句子产生“head weight”的感觉时，句子结构则遵循“end weight”的原则，即，把较长的主语全部置于句子尾部。前面空掉的主语位置用it来代替，担当形式主语的功能。
而汉语并不具有这类明显的特征，学生对英汉两种语言结构差异知之甚少，或者略有所知，在真正的运用中，也未必能够正确的体现出来。多数学生都本着汉语式的思维，一遇到“某人做某事是怎么样的/是什么”就习惯性地写成sb.+ is/are +adj./n. + to do sth.
总之，备考雅思写作考试，学会使用词汇还是要在语法功底较好的基础上，当你要表达一个意思时，语法却错误，那样也会闹出笑话。因此，考生要有条不紊的进行备考，用对的方法做对的事情，一定会收取最丰富的果实。
