2021四级作文真题及答案【二】

This cartoon is silly, and yet compelling: a large customer holds a hopelessly small piece of cloth as the tailor carefully measures. Such an image suggests that one needs to consider practical reality in the pursuance of goals. Merely acting on one's desires, while ignoring the facts at hand, cannot lead to success.

The fact that currently there are more graduates than jobs reminds us of the importance of rational thinking. Every year approximately 3 million students graduate from universities and begin looking for work. Many of them fail to find suitable employment because there are simply not enough opportunities to accommodate such great numbers of graduates. In addition, however, one might also cite flawed individual assessment as a reason.

In order to create a realistic target for one's future, one must make rational decisions and prepare accordingly. A student who aims to be a surgeon, for example, must take care to acquire opportunities to do clinical practice and gain sufficient knowledge. In other words, customers would do well to take accurate measurements before purchasing their fabric. A small piece of cloth cannot adequately clothe a large person.
