You are required to write at least 150 words but no more than 200 words. 参考答案 Nowadays, there has been a heated discussion as to a better choice between attending college at home and abroad. Views on the topic vary greatly among people from different walks of life. Some believe that it is a better choice to study in domestic colleges, but others consider it better to study abroad. I totally agree with the latter idea for the reasons presented below. To begin with, it harms the society in that the greater the competition is, the higher the recruitment requirements will become. Therefore, with experiences of studying abroad, graduates will become more competitive in job hunting. Furthermore, it is beneficial to the students themselves to study abroad. Without the choice to pursue overseas study, many great scholars today would never have achieved such great success. From my perspective, it is crucial that the government should encourage people to pursue overseas study. Also it is crucial that people should understand the meaning and value of attending college abroad. Only in this way can we achieve greater success. 作文二:文科还是理科 Directions: Suppose you are asked to give advice on whether to major in humanities or science, write an essay to state your opinion.

Of all the issues, one might concern the high school graduates the most, and it is if there are two options: to major in science or humanities. As for me, I prefer the latter. Why,you may wonder, should I prefer to major in humanities. The reasons responsible for it can be listed as follows . Among the most important reasons cited by people is that to major in humanities,directly or indirectly,can not only enrich our basic knowledge about the diversified culture but also sharpen one’s insight in daily routine,which is of great importance in one’s growth. What’s more, to study humanities can give us an independent personality and a deeper vision towards the world, if it were not for those two attributes, how could we achieve great goals in this dog-eat-dog world. Above all, in such a society where emphasis,more often than not,is laid on the depth of one’s thought, to choose humanities as one’s major, must be the best way .
