形式主语it雅思写作中怎么用

在看学生的雅思写作文章过程中，总会看到这样的文字，“college graduates are difficult to find jobs”，“parents realise the needs of their children is extremely important”，“students cannot focus on their study because of tiredness is a fact”，“Clearly, rush hours emerges in the early morning as well as early evening which is most busy in a day as a whole in London.” 这几个句子，虽然长短不一，结构不同，话题各异，但是，学生对形式主语it的驾驭能力的欠缺，是可见一斑的。

二、形式主语

(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

It is + wrong/right/wise/cruel/naughty/selfish + of sb. + to do sth.

据本人统计，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。

实例3：Clearly, rush hours emerges in the early morning as well as (in the) early evening which is most busy/the busiest in a day as a whole in London.

修改建议：这个句子的结构应该是无可厚非的(语法就不说啦)，但是，按照雅思评分的标准，句式稍微做一下调整，会更漂亮：如：It is clear that rush hours emerge in the early morning as well as in the early evening which is most busy/the busiest in a day as a whole in London.或者改成It is demonstrated that rush hours emerge in the early morning as well as in the early evening which is most busy/the busiest in a day as a whole in London.这样一个小小的调整，其句子修改前后的效果是显而易见的。

(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.

三、总结

建议学生在雅思学习中，采取步步为营的四步走战略战术，循序渐进：首先，记住句型结构;其次，模仿写作;之后，进行独立创作;最后，形成属于自己的模板句型。作为雅思写作学习中可控制的因素，我们可以培养句式运用的习惯，使习惯称为自然。为了我们雅思的学习这个努力是值得的，it pays in the long run.

以上就是小编为大家带来的全部内容，希望大家能熟练的掌握it主语在雅思写作中的应用，平时就勤加练习，这样才能最快的掌握it主语的用法。
