[简答题]比较单向沟通和双向沟通的异同？

参考答案: 从发送者与接受者的地位是否变换的角度来看，两者之间的地位不变是单向沟通，两者之间的地位不断变换是双向沟通。单向沟通比双向沟通的速度快；双向沟通比单向沟通准确；双向沟通中，接受信息的人们对自己的判断比较有信心，传达信息的人们感到压力较大；双向沟通容易受干扰，并缺乏条理性。如果需要迅速的传达信息，单向沟通的效果好，但准确性差；如果需要准确的传达信息，双向沟通较好，但速度较慢。

What Does the Expansion of College Enrollment Bring？
参考答案:Nowdays, a hot topic which people are talking about is the expansion of college enrollment. This new step taken by the government benefits individuals, institutions of higher learning, and the nation as well. First, the expansion meets people’s growing need for higher education and the general public receive the direct benefits. High school graduates are delighted with the news, because they’ll have more chance to attend college. Second, the expansion does good to our country, too. It’ll stimulate consumption, and most important of all, with the expansion, our country will have more well-educated citizens and professionals, which is vital to the development of the country. Last, the new policy provides a good chance of development for colleges and universities.
However, while people are cheering the policy, some colleges and universities are faced with problems arising in the process of expansion. For example, some don’t have enough accommodation, classrooms, teaching facilities and teaching staff.
How to solve these problems Obviously, one possible solution is to build more student dormitories and more classroom buildings. The difficulty is where to get the money I think, the expansion itself has brought more funds than before. In addition, the local government should contribute some. With the combination of the two sources, these colleges and universities can overcome the difficulties.
