用词不当
The absence of groupwork is a disaster for teenagers in modern society.
评：groupwork是“分组”或者“小组集体任务”的意思。应改为teamwork“团队合作”，用词不当而导致表达出来的意思就风马牛不相及了。
You will be dangerous if you keep moving without a clear view of the whole picture.
评：dangerous表示所修饰的对象是“带来危险的，有危险性的”，而be in danger才是“身处险境”的意思。到底谁才是威胁呢?
Firstly, the job, providing the opportunity for students to utilize what they learned in class, might effect their further development.
评：模样长得像，意思可不同了。这里想用动词affect表示“影响”，却误写为名词effect“效果”，一字千里啊!
搭配错误
Nowadays, people are crazy pursuing to be excellent.
评：这位同学显然记错了be crazy about sth. 这个用法，写出来的句子自然会出问题啦。
Besides, public speech can effectively increase your communication skills, which facilitate your salesman career.
评：此处是一个明显的动宾搭配错误。“提高……技巧”应该是improve the skills，而不是increase the skills.
词性错位
I will forget my sad and pressure from the work and the study.
评：sad是形容词，而这里明显需要一个名词，应该是sadness。
Although making money is a priority for most people, spending time with the family is equal significant.
评：形容词significant前需要用副词来修饰，所以equal应该改成equally。
时态混乱
Although I have no work experience when I was a teenager, I always dreamed about having a job.
评：过去时的句子中冒出了现在时，同学你太粗心了，要仔细检查哦。
I would explain my view in the following paragraphs.
评：应该改为would like或是will，这两种说法混合使用导致把时态上的混乱。
通过以上几个例子，希望同学们可以举一反三，在托福写作练习和考试中都不要出现这些错误。
