小学英语语法最容易犯错的知识盘点

　　英语中我们经常会遇到一些习惯的语法，导致我们犯了自己都不知道的错误，下面小新就列出20个常见错误，大家一定要注意哦！

　　1. All the balls are not round. 翻译成汉语：

　　所有的球都不是圆的。(×)

　　并不是所有的球都是圆的。(√)

　　[析] all, every, both等词和not连用时，not通常放在all, every, both的后面，一般情况下表示部分否定，意为"并非……都……"。

　　2. The Smiths have moved Beijing. (×)

　　The Smiths have moved to Beijing. (√)

　　[析] 不及物动词后接名词或代词作宾语时，要在动词之后加上适当的介词;但不及物动词后接home, here, there等副词作宾语时，动词之后不必加任何介词。

　　3. The box is too heavy for him to carry it. (×)

　　The box is too heavy for him to carry. (√)

　　[析] the box既是这句话的主语, 也是不定式to carry的逻辑宾语，若句末再加上it，就和the box重复了。

　　4. Each of the boys have a pen. (×)

　　Each of the boys has a pen. (√)

　　[析] 复数名词前有表个体的each of, one of, every，either of等词组修饰，或有表否定的neither of, none of 等词组修饰时，谓语动词要用单数形式。

　　5. Neither he nor you is good at English. (×)

　　Neither he nor you are good at English. (√)

　　[析] either... or..., neither... nor..., not only..., but also... 等词组连接句子的两个主语时，谓语动词遵循"就近一致原则", 即由靠近谓语的那个主语决定谓语的人称和数用何种形式。

　　6. Ten minus three are seven. (×)

　　Ten minus three is seven. (√)

　　[析] 用英语表示加(plus)、减(minus)等数学运算时，谓语动词也用单数形式。

　　7. The number of the workers in this factory are about 5,000. (×)

　　The number of the workers in this factory is about 5,000. (√)

　　[析] the number of表示"……的数量"，谓语动词用单数形式;a number of 的意思是"若干"或"许多"，相当于some或a lot of，和复数名词连用，谓语动词用复数形式。

　　8. Hello! I have important something to tell you. (×)

　　Hello! I have something important to tell you. (√)

　　[析] 形容词或动词不定式修饰不定代词作定语时，修饰成分要置于不定代词之后。

　　9. His son is enough old to go to school. (×)

　　His son is old enough to go to school. (√)

　　[析] enough作形容词修饰名词时，可以放在名词前，也可放在名词后;作副词修饰形容词或副词时，只能放在形容词或副词之后。

　　10. Here is your sweater, put away it.(×)

　　Here is your sweater, put it away. (√)

　　[析] put away, pick up, put on等"动词+副词"构成的词组后接代词作宾语时，代词只能放在动词和副词之间。
