专四英语作文 篇4

Just as is revealed in the pictures above, people are generally classified into two types: the pessimistic and the optimistic. We can see in one picture some people, long-faced and downhearted, are counting the nights by the shadows while in the other picture the happy-go-lucky people are enjoying the starry nights. What a contrastive view! Remember, it is not the bad thing that determines our state of mind but the way we look at it matters. (描述点题段) (以小到大)

An example that comes to mind is SARS crisis that has recently torn apart and ravaged most of China. Admittedly, it has cost us quite a lot. Some people suffered from health damage and still some even lost their lives. And our economy suffers a temporary setback and a slowdown. However, we still have learnt and benefited a lot from it. (举例说明段) 4. First things first, we are more concerned than never before with our health, and the environment we live in. Additionally, we tried and bettered and are still bettering our mechanism to respond to unexpected crises. These and other lessons at the expense of blood, tear, toil and sweat are benefiting and continue to benefit us and generations of Chinese to come. (分析问题段)

The best way to overcome the frustrations brought about crises is to always take a positive outlook on life. Just as a well-known ancient Chinese notion goes, the past lessons if not forgotten are good teachers for us all. If we can bear in mind sufferings and ordeals we have experienced, then our sufferings will not go unrewarded. (前瞻感言段)

范文赏析

College Students Starting Their Own Undertakings

Nowadays there are many college students who choose to start their own undertakings instead of ?nding a job after graduation. The government encourages this practice, and provides many preferential policies and facilitation measures for college students. As far as I’m concerned, an array of integrated factors contributes to this.

引言部分 ：作者先提出大学生毕业后不去找工作而是选择创业这个现象，然后用as far as I’m concerned 引出自己的看法 。

The ?rst factor that should be mentioned is that college students are facing severe employment situations. Many college graduates couldn’t find ideal jobs, which forces them to set up their own businesses. Another equally important factor is that some ambitious college students are not satisfied with being employed by others. They want to develop and prove their talents by running their own companies.Besides, the government’s encouragement and the media’s reports on college students venture stars have stimulated more college students’ enthusiasm to take this way.

主体部分：在主体部分，作者陈述了三个原因，分别使用了the first fact or，an oth er equ ally important factor和besides 来连接这三个原因。

As for me, it is a good choice for college students to start their own undertakings. However, it is a very difficult cause, which needs firm determination, clear mind, the ability to endure hardship and a feasible project. Therefore, they should think it over and make full preparation before deciding to start their own businesses.

总结部分 ：作者用as for me来引出自己的观点，与首段不同；作者认为创业是个不错的选择，但是应仔细考虑并做周全的准备。

亮点回放

1. undertaking : “事业 ，企业 ，保证”；此处作 “企业”解 ，文中表示“创业 ”的表达 方式很多 ：start their own undertakings ，set up their own businesses ，running their own companies ，start their own businesses等 。近义词的使用使文章不单调，充满变化性。

2. practice : “练习，习惯，业务”；此处表示 “做法 ” ，常用的搭配还有international practice（国际惯例 ），best practice（最优方法 ）等 。

3. preferential: “优先的，特惠的”；此处也可以使用favorable terms来表示“优惠条件”。

4. facilitation measure: “便利性措施”。

5. an array of: “一系列的”；近义词还有a series of ，a number of ，a set of等 。

6. integrated: “综合的，整合的”；这里指“综合性 的因素”。

7. ambitious: “野/雄心勃勃的” ；此处也可以用enterprising （有事业心的，有进取心的 ） 来代替 。

8. run : 通常同学们只用该词的常用意思 “跑 ” ，此处表示 “经营 ，运 营” ，近义词为operate ，manage等 。

9. stimulate: “刺激 ，激励” ；此处可以用motivate ，inspire ，rouse来替代 。

10. cause: 常用作动词，此处作名词，表示“事业 ，事情”，也可以简单地使thing来表示。

11. determination: “决心” ；通常考生会使用make up one’s mind来表示 “下定决心做某事”，但是determination 的使用更为正式 。

12. feasible: “可行的” ；此处也可以使用reasonable ，practicable ，workable ，achievable等。

How to Keep Psychologically Healthy?

Nowadays more and more people are concerned about mental health issue. It is reported that the number of people committing suicide is on the rise. Many of them committed suicide just because of some little frustration such as failing an exam. If they had paid more attention to their mental health, they might not have reacted in such an extreme way.

How to keep ourselves psychologically healthy? First, we should adjust ourselves to the new conditions. When we go to a university as freshmen, or go to work in a strange city, we may become nervous because everything is so unfamiliar. The only way out is to adjust ourselves to the new conditions and shake off the anxiety quickly. Second, we should know our-selves well and admit that we are just ordinary people. Knowing that ordinary people may not be good at everything, we can easily accept some small failures in our lives. Third, we should try to share our feelings with friends. By doing this, we are assured that any difficulty can be solved since we are not alone.

It is very important for us to be psychologically healthy, and we should pay more attention to our mental health.
