雅思写作中那些可以使用的形式主语

(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。

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。
