更进一步说，“have”和“there be”句型都可以简化成更简单的介词“with”结构，如以下所示：

On the table is a box. There is a cover beside it.

这两个小句子是小作文的流程图中经常要用到的具体描写事物的句型，凡是描写具有某种属性或者带有某种外部特征都可以用”with”结构表达，所以上述两句可以合并成：On the table is a box with a cover beside it.

除了一般的“某个人做某件事情”和“…have…”句型，常见的人化主语的句型还有很受考生偏爱的几个情态动词，如can, may, should等。朗阁海外考试研究中心建议考生一般前两个可改成It is likely /possible to do/ that….；后一个改成It is necessary/ imperative/ highly expected/ suggested that sth. be done.的句式，请看下面的例示：

We can go anywhere we like with our bicycle. →

It is possible for us to go anywhere we like with our bicycle.

To curb global warming, our government should promulgate new laws to govern the felling of trees.→

To curb global warming, it is imperative that our government promulgate new laws to govern the felling of trees.

归纳起来说，议论文中我们要积极避免“某个人”做主语，尽量用不定式、动名词或者一个从句做主语，谓语动词用评价性的动词充当，这样就可以由记叙文性质的“过程性句式”顺利转化成更符合议论文文风的客观评价性的句式。

二 被动句式的使用

在比较正式的新闻、商务、法律等英语文体中，被动句式因为其更突出客观性的宾语或者事实被广为使用。雅思的图表分析和议论文都是比较正式的文体，所以朗阁海外考试研究中心建议考生也应该注意多用被动句式。尤其是在以下两个方面：

1.主语不确定

Someone murdered the millionaire last night.→

The millionaire was murdered last night.

2. 主语是泛指很多人或者大部分人

To improve the air quality, we should reduce the use of private cars. →

To improve the air quality, the use of private cars should be reduced.

Most people think that we can get a large share of benefit in the sales campaign.→

It is widely believed that we can get a large share of benefit in the sales campaign.

被动句的用法不仅体现在主句中，在从句、非谓语动词短语中都有可能用到，如：

It is important for nations all over the world to join hands to control the software piracy. →

It is important for nations all over the world to join hands to have the software piracy controlled.

I don’t expect that she returned. → She is not expected to have returned.

I am not sure whether the college graduates will find jobs in the financially difficult year. →

I am not sure whether the college graduates will get employed in the financially difficult year.

但是因为汉语中本来是没有被动句式的，所以受汉化思维的影响很多考生不会想到这一点。这就要求我们对此要引起足够的重视，并且在平时多加练习以培养对其敏感度。
