Write a composition based on the following suggestions with no less than 200 words: 1.你的朋友需要在历史和计算机两个专业中作出选择。他实际上很喜欢历史，然而，他被告之，如果选择计算机专业，以后找工作较容易。比较两专业的优与劣，然后写信给他提出你的建议。 2．近年来，大学毕业生越来越难找到较好的工作，因此有人认为大学教师应该将更多的精力放在实用性的课程上，譬如计算机、商贸等，然而，对于历史、地理等传统基础课程则可投入较少精力，谈谈你的观点。 3. 城市建设中，我们不可避免地要拆除一些旧房子来改善基础设施。因此，不同的人有不同的看法。有人认为旧房子不该拆，因为它们有的具有历史意义或文物价值，值得保留；而有人却认为应该拆，因为它们阻碍了城市建设。你的看法如何。

Nowadays, the university graduates have found it’s been more and more difficult to find a better work, therefore some people thought the university professors should put more energy in the usable curriculum, such as: computer, business trade and so on. As for traditional foundation curriculum, like history, geography, and so on, it seems there need less energy to invest in.For instance, one of my friends likes history more than computer, but he has to take computer as his specialty because it is easy to look for a job. Likewise, in the urban construction, we inevitably must demolish some old houses to improve the basic structure. Of course, the different person has the different view. Some people thought the old house should not tear down because they have the historical significance or the cultural relic value. However, in my opinion, I believe those hindered the urban construction should be removed for practical reason. It is the same for graduate students to switch their majors, unless those who are wealthy to sustain their interests.
