写作思路：围绕出国留学的弊作为中心思想，结合自身感受得描述，正文：

First of all, the cost of studying abroad is expensive.

首先，出国留学的费用是昂贵的。

Specifically, these people have to spend a lot of money on tuition and living expenses, which not everyone can afford.

具体来说，这些人不得不花费一大笔钱在学费和生活费上，而这并不是每个人都负担得起的。

In addition, for those students who lack the ability to live independently, studying abroad is a great challenge.

此外，对于那些缺乏独立生活能力的学生来说，出国留学是一个巨大的挑战。

If they can't take good care of themselves, their academic achievements will be affected to a great extent.

如果他们不能照顾好自己，他们的学习成绩将在很大程度上受到影响。

Last but not least, studying abroad may have a negative impact on students' psychology.

最后但并非最不重要，出国留学可能会对学生的心理产生负面影响。
