一、引言

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

(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.

It;is;+;necessary/hard/important/difficult/possible/common;+;for;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)

C.;It;is;difficult;to;say;who;has;the;right;to;judge;whether;children;working;is：“wrong”;or：“valuable”.;(Cambridge;3，;P164，;Task;2)

D.;…，;it;is;important;to;remember;that;children;need;to;develop;skills;other;than;intellectual;ones;and;…(Cambridge;3，;P168，;Task;2)

E.;Finally，;I;think;that;it;is;also;important;to;remember;that;children;need;to;relax;as;well;as;work;…(Cambridge;3，;P168，;Task;2)

F.;Because;people;interpret;happiness;for;themselves;in;so;many;different;ways，;it;is;difficult;to;give;ang;definition;that;is;true;for;everyone.;(Cambridge;4，;P165，;Task;2)

G.;It;is;quite;common;these;days;for;young;people;in;many;countries;to;have;a;break;for;studying;after;graduation;from;high;school.;(Cambridge;5，;P165，;Task;2)

H.;They;may;think;that;it;is;better;to;continue;in;a;particular;job，;or;to;do;sth;completely;different;from;from;a;university;course.;(Cambridge;5，;P165，;Task;2)

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。

(3)学生写作实例

(3)学生写作实例

实例1：It;is;quite;obvious/evident/apparent;that;the;quantity;of;families;who;tends;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‘s;love;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.

这是XVCC23强化班里一位基础较好的学生的写作实例，其中的语法、措辞方面的错误已经进行了修改。

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t"

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.
