備考托福寫作一定要打好語法基礎，如果寫作中出現太過明顯的語法錯誤肯定會影響寫作成績。下面，牛學君為大家整理了6類托福寫作中常見的語法錯誤，希望大家在寫作中能夠避免。

1. 托福寫作常見語法錯誤之句子缺少連詞

兩個句子之間不能只用逗號連接，要有連詞。

誤：My sister loves to dance， she is very good at it.

2. 托福寫作常見語法錯誤之句式不平行

句子中并列的成分應該是相同的結構。

誤：I like to eat Japanese and eating Thai food.(eating-> eat)

誤：Teenagers are more influenced by their peers than their parents.(than their parents-> than by their parents)

3. 托福寫作常見語法錯誤之句子不完整

句子缺少主語或謂語。

誤：Because some necessary procedures such as transporting the factories， modifying equipment or planting more trees.

4. 托福寫作常見語法錯誤之句意重復或冗余

誤：The low-priced car was inexpensive.(low-priced和inexpensive重復)

誤：personally， I believe what the newspaper prints.(personally和I believe重復)

5. 托福寫作常見語法錯誤之時態，語態不一致

我們來看幾種常見錯誤(句例說明)：

She did not adapt to the environment, but with time passing by, they find him more and more proficient.

she 和him是怎么個意思咧?

I shall use my father's experience as an example. My father went to Australia several years ago. He see many birds and animals. 明明是過去，see怎么穿越回來了?

The gift I made are very pretty. gift是單數啊，are是怎么回事?

6.托福寫作常見語法錯誤之連詞類缺失

Successful men will have many places to live, a country house can provide a nice environment to relax, then it will be a new start point, but will not be an end one.

大家暫且忽略語法問題，且看這個句子。這個句子的第一個問題就是連詞缺失：在live和a country house 之間原作者使用逗號銜接的，但是呢，逗號并不能代替and等連詞的作用。因為 Successful men will have many places to live和a country house can provide a nice environment to relax都是兩個完整的句子，而沒有主從依附關系，所以必須得有連詞(and，but，therefore)等連接才能保證句子有效。

總結：

缺連詞的另一大原因是很多同學不知道什么是連詞，什么不是。and or but 是最有名的三個連詞。但是!however, so, yet, nevertheless也是連詞!!!可以連接兩句句子!

以上是牛學君為大家整理的托福寫作中常見的語法錯誤，希望對大家備考有幫助。托福寫作考試中建議大家留出2-3分鐘檢查，主要檢查和修改文章中的語法錯誤。
