托福写作常见语法错误有哪些?

1. 不完整句子(Fragments)

不完整句子指的是句子当中缺少主语或谓语等,无法形成一个完整的句子。

比如:A movie that inspires deep emotions.(只有名词加定语从句,不是完整的句子)

应改为:She went to see “The Silver Star”, a movie that inspires deep emotions.

2. 不间断句子(Run-on Sentences)

不间断句子指的是用逗号来连接两个完整的句子。

比如:There is increasingly widespread reliance on electronic mail, some people still resist using it, especially those who prefer handwritten letters.

应改为:Although there is increasingly widespread reliance on electronic mail, some people still resist using it, especially those who prefer handwritten letters.(根据两句之间的关系,加入连词)

3. 主谓不一致(Subject-verb Disagreement)

主谓不一致指的是句子中主语与谓语没有保持数的一致。

比如:Many students thinks tomorrow is a holiday.

应改为:Many students think tomorrow is a holiday.

再比如:The use of cell phones during concerts are not allowed.

应改为:The use of cell phones during concerts is not allowed.

4. 可数名词“裸奔”

可数名词“裸奔”指的是可数名词之前没有冠词,也没有变为复数形式。

比如:Even expert or scholar specializing in a certain field might cover a vast spectrum of knowledge in order to succeed.

应改为:Even experts or scholars specializing in a certain field might cover a vast spectrum of knowledge in order to succeed.(可数名词变复数形式)

5. but/ however

but和however都表示转折,但是but是连词,而however是副词,也就是说however是不能来连接两个独立分句的。

比如:Printed books are limited in space, however, space is not an issue for electronic ones.

应改为:Printed books are limited in space. However, space is not an issue for electronic ones. (用句号将原句分成两个独立分句)

6. therefore

therefore也是副词,表示“因此”,它也不能连接两个独立分句。

比如:Pupils always look to their teacher for guidance, therefore the influence that a teacher has could never be underestimated.

应改为:Pupils always look to their teacher for guidance; therefore the influence that a teacher has could never be underestimated.(用分号将两个独立分句连接起来)

或者:Pupils always look to their teacher for guidance, and therefore the influence that a teacher has could never be underestimated.(用and将两个独立分句连接起来)

7. there be句型

there be句型中be动词本身已经是谓语部分,不能再出现谓语动词。

比如:There are many people prefer to wear clothes made of natural fibers.

应改为:There are many people who prefer to wear clothes made of natural fibers.(后面prefer to改放到定语从句里)

8. 比较对象的对等

在比较结构中,注意前后比较事物要对等。常用that和those来指代“比较结构”里先前提到的名词。

比如:The merits of serious movies far outweigh funny movies.

应改为:The merits of serious movies far outweigh those of funny movies.(those指代的是前半句的比较对象merits)
