2015教师招考

句型变换·肯定句变成否定句

1. 若原句中有动词be

原句中含有be动词(am, is, are, was, were) 和助动词(have, has, had) 和情态动词(can, shall, will, may, should, would, might, had better等)时，要在动词后直接加not。如：

His mother has already called the police for help.

His mother ________ called the police for help ________. (答案：hasn’t, yet)

2. 若原句中没有动词be

原句中没有be动词，助动词或情态动词时，要在行为动词前加助动词(do, does, did)与否定副词not的缩写形式。另外，还需要将原句子中的some改为any; too改either;already改为yet。还需要分清do, have等是实义动词还是助动词。如：

The old man hurt his leg last Wednesday.

The old man ________ ________ his leg last Wednesday. (答案：didn’t hurt)

3. 若原句中有不定代词

原句中含有every, everything, all, both等不定代词或both…and…, a lot of 等短语时，与否定副词not连用属部分否定。把这些不定代词变成neither, none, no one或把both…and…变成neither…nor…时，才是全部否定。如：

Both Joy and Sam like singing Beijing Opera.

________ Joy ________ Sam likes singing Beijing Opera.(答案：Neither, nor)

4. 若原句为复合句

在含有宾语从句的主从复合句中，当主句的主语是第一人称，谓语动词是think时，如果要否定后面的宾语从句，习惯上否定主句的谓语动词。如：

I think she will come here soon. →I don’t think she will come here soon.

肯定句变否定句的技巧

一、动词后直接加not。原句中含有be动词(am, is, are, was, were) 和助动词(have, has, had) 和情态动词(can, shall, will, may, should, would, might, had better等)时，要在动词后直接加not。如：

His mother has already called the police for help.

His mother ______ called the police for help ______. (答案：hasn’t, yet)

二、原句中没有be动词，助动词或情态动词时，要在行为动词前加助动词(do, does, did)与否定副词not的缩写形式。另外，还需要将原句子中的some改为any; too改either;already改为yet。还需要分清do, have等是实义动词还是助动词。如(from zkenglish.com)：

The old man hurt his leg last Wednesday.

The old man ______ ______ his leg last Wednesday. (答案：didn’t hurt)

三、原句中含有every, everything, all, both等不定代词或both…and…, a lot of 等短语时，与否定副词not连用属部分否定。把这些不定代词变成neither, none, no one或把both…and…变成neither…nor…时，才是全部否定。如：

Both Joy and Sam like singing Beijing Opera.

______ Joy ______ Sam likes singing Beijing Opera.(答案：Neither, nor)

四、在含有宾语从句的主从复合句中，当主句的主语是第一人称，谓语动词是think时，如果要否定后面的宾语从句，习惯上否定主句的谓语动词。如：

I think she will come here soon. →I don’t think she will come here soon.

句型变换复习·陈述句变感叹句

感叹句通常由what, how引导，表示赞美、惊叹、喜悦、等感情。what修饰名词，how 修饰形容词、副词或动词。感叹句结构主要有以下几种：

How+形容词+a +名词+其他成分!

How+形容词或副词+其他成分!

What+名词+其他成分!

What+a+形容词+名词+其他成分!

What+形容词+复数名词+其他成分!

What+形容词+不可数名词+其他成分!

把一个陈述句变为感叹句，可用“一断，二加，三换位，四改号”的方法来做。

第一步：“一断”是在谓语后把句子断开。如：

He is / a good student. She works / (very) hard.

第二步：“二加”是在第二部分前加上how或what。如：

He is / (what) a good student. She works / (how) (very) hard. 注：如有very, too, quite等词应去掉。

第三步：“三换位”是把第一、二部分交换位置。注意句中有关单词的大小写。如：

What a good student he is. How hard she works.

第四步：“四改号”是把原来的句号改为感叹号。如：

What a good student he is! How hard she works!
