　　北京新航道雅思专题小编长期为同学们整理雅思写作相关备考素材，以帮助和辅助同学们地备考雅思写作，请大家持续关注，以便及时获取考试材料和资讯。以下是详细内容：

　　我们有时为了强调而把否定词和词组放在句首，这时句子结构应倒装。例如：

　　1) On no account should we follow blindly.我们决不应当盲从。

　　2) No where has the world ever seen such great enthusiasm for learning as in our

　　country.没有任何其他地方有我国这样高的学习热情。

　　五、 含有it的结构

　　考生病句：

　　1. As is known to all of us that science and technology play an important role in the

　　development of society.

　　2. It is known to us, practice makes perfect.

　　正确表达：

　　1. It is known to all of us that science and technology play an important role in the

　　development of society. (或:As is known to all of us, science...)

　　2. It is known to us that practice makes perfect. (或:As is known to us, practice...)

　　评议与分析：

　　例句1是93年12月六级考试11分作文的评分样卷句子，例句2选自97年1月四级考试作文。很显 然，两个考生混淆了it和as的用法。如果用it作形式主语，后面的主语从句必须由that引起;如果用 as，则后面不能用that，因为as是关系代词，代表practice makes perfect。

　　It 在英语中是个相当活跃的代词，在写作中我们常要使用它。以下几种用法应熟练掌握，并能灵 活运用。

　　1.作形式主语

　　It is necessary for us to master a foreign language skillfully. It makes difference whether

　　we could purify the air or not.

　　2.作形式宾语

　　We find it rather difficult to prevent people from doing that. Modern science has made it

　　possible for babies to grow healthily and for people to live longer.

　　3.引导强调句

　　It is only by this way that we can achieve success. It was then that people began to realize

　　the importance of controlling population.

　　从语法结构来看，上述的句子都不难，或者可以说是考生相当熟悉的。然而在写作考试中，多数考 生缺乏运用自己已掌握的句式的意识，而以自己头脑中拼凑的中式英语取而代之。其实，只要能恰当地 运用上述的任何一个句式，考生的作文就会出现闪光点，就会取得比较好的成绩。
