AEIS英语语法：被动语态要点简述

　　AEIS英文考试难度大，要求高，主要表现在语法和词汇两方面。

　　在备考中存在这样几种误区，相当一部分家长认为AEIS考试的语法题所占分值不大，且学生在学校里的语法学得挺扎实的，对孩子的语法非常自信。

　　其实不然！

　　首先新加坡学生的语法框架一般在小学阶段就已全部构建完成，所以国内中小学的英语语法水平是达不到新加坡同年级的标准的。

　　而关于AEIS考试，就拿写作为例，写作一般都要求句式的多样性，对学生句法的掌握和熟练运用有较高的要求。今天课窝考试网主要说说关于被动语态的考点。

　　被动语态的构成方式：be + 过去分词，口语只也有用get / become + 过去分词表示。被动语态的基本用法：不知道或没必要提到动作的执行者是谁时用被动语态。强调或突出动作的承受者常用被动语态(by短语有时可以省略)。　　

　　使用被动语态时应注意的几个问题。

　　主动变化被动时双宾语的变化。看下列例句。

　　My friend gave me an interesting book on my birthday.

　　An interesting book was given to me(by my friend)on my birthday.

　　I was given an interesting book (by my friend)on my birthday.

　　主动变被动时，宾补成主补(位置不变);(作补语的)不定式前需加to。

　　The boss made him work all day long.

　　He was made to work all day long(by the boss)

　　短语动词变被动语态时，勿要掉“尾巴”。

　　The children were taken good care of (by her).

　　Your pronunciation and spelling should be paid attention to.

　　情态动词和be going to、be to、be sure to、used to、have to、had better等结构变被动语态，只需将它们后面的动词原形变为be +过去分词。

　　当句子的谓语为say、believe、expect、think、know、write、consider、report等时，被动语态有两种形式：

　　(A)谓语动词用被动语态，动词不定式作主补。

　　(B)用it作形式主语，真正的主语在后面用主语在后面用主语从句来表示。如：

　　People say he is a smart boy.

　　It is said that he is a smart boy.

　　He is said to be a smart boy.

　　People know paper was made in China first.

　　It is known that paper was made in China first.

　　Paper was known to be made in China first.

　　类似句型有：It is said / known / suggested / believed / hoped/ thought that …
