1、用词不当
学生们在托福写作备考中或多或少都会有一些用词不当的问题，但是要注意的是一些最最基本的错误是不能犯的。
In the show, if participators answer twenty problems that the host mentioned correctly, they will get five hundreds thousand U.S. dollars as a prize.
problems应改为questions
2、拼写错误
这里的拼写错误不是指在考试时候的手误，而是本身对托福写作词汇拼写记忆的错误。
In conclusion, issue of whether parents are the best teachers is a complex one, requiring subjective judgement, consequently, there are no easy or certain answers.
judgement应改为judgment
3、乱用大词
First of all, children can earn money from their jobs, although there isn't too much, but they will keep their salary gingerliness.
这里的gingerliness根本是不知所云。该句子还有以下问题：
1)该新托福写作题目是讲学生是否应该做兼职，因此children的出现就显得很莫名其妙;
2)although和but是不能连用的;
3)指代不明，they不知道是指代前面的什么;
4、表达中式
The second argument-it might have been noticed by others-is that in some occasion, it is quite difficult to compare parents to teachers because parents are a kind of people, teachers are a kind of vocation.
该句的表达过于中式化。
5、表意重复
They shocked their friends, devastated their families, crushed their best friends.
前面已经提到了朋友，后面又提到朋友。
The show is so compelling but attractive.
compelling和attractive是同义词，所以这里这么写就让人不明白。
6、固定用法错误
To some extends, I agree with the author's general assertion that if parents also have a comprehensive sense of professional knowledge.
To some extends应改为To some extent
7、例证夸张
For example, when a doctor faces a patient who has got cancer, the doctor cannot tell the truth, for the truth may cause the patient's immediate death.
虽然善意的谎言是必要的，但是其功效显然没有这么大。
8、成分多余
According to a comprehensive investigation which is carried out by Chinese Academy of Social Sciences shows that there is an increase in the number of university students who are taking part-time jobs.
该句中的shows that是多余的成分。
9、词性混乱
However, the questions such as "Have you ever regretted marrying your husband" may be very privacy and embarrassingly.
句子中的privacy和embarrassingly应该改成private和embarrassing。
10、时态错误
新托福写作备考中的大作文一般使用现在时态，除了拿过去事件作为例子，用过去时态。
Some people claimed that news media has enormous influence and is a detrimental creation.
claimed应该改为claim。
可以看出新托福写作中存在的毛病可不少，这需要大家在托福写作备考时就注意，改进后才能让大家的托福写作有所进步，希望各位能够重视。
