正确答案：Recently, numerous reports related to children's dependence on their parents on various media have, once again, aroused wide concern among public about kids' lack the ability to face their lives by themselves. It is widely accepted that excessive reliance on one's parents is bound to be harmful to his prospect and thus it is necessary that some urgent actions be taken to alter current trend.
For one thing, more opportunities should be given to children to participate in different competitive and cooperative activities, for competition is one of effective ways to lead them to achieving outstanding accomplishments and cooperation can build trust between each other and help to bring long-term relationship among peers. For another, it is suggestive that children receive some outward-bounds, which are beneficial to kids' physical and emotional endurance, to inspire children's underlying potentials and shape their best character and consequently cultivate their awareness of independence.
In a nutshell, parents are supposed to be subject to the limitations of traditional concepts of raising a child; on the contrary, children ought to be offered more chances to explore as many as possible areas in their lives to find their optimal careers. Accordingly, the cultivation of the ability to be independent might be regarded as a basic education, which plays a crucial role in a child's all-round development.

第5题：
Given that you have a class B IP address network range, which of the subnet masks below will allow for 100 subnets with 500 usable host addresses per subnet?
A．255.255.0.0
B．255.255.224.0
C．255.255.254.0
D．255.255.255.0
E．255.255.255.224
正确答案：C
解析：Explanation:
Using the 2n-2 formula for host addresses, 29-2 = 510 host address, so a 9-bit subnet mask will provide the required number of host addresses. If these 9 bits are used for the hosts in a class B network, then the remaining 7 bits are used for the number of networks.
Again using the 2n-2 formula, we have 2n-2 = 126 networks that are available.
Incorrect Answers:
A. This will provide for only 1 network with 216-2 = 65534 hosts
B. This will provide for 6 networks with 8190 host addresses.
D. This will provide 254 networks and 254 hosts.
E. This will provide 2046 different networks, but each network will have only 30 hosts.

Campus Activities
Campus activities have been organized in many universities and colleges.
These activities range from academy to recreational, such as academic reports, speech contests, poet’s club, painting clubs, singing and dancing groups, etc.
These activities provide students with two major advantages. First of all, they play a positive role in improving students’ studies. Due to their heavy schedules, students are often buried in textbooks and seldom expose themselves to a colorful life. But the various activities provide opportunities for them to relax themselves and enrich their minds. In addition, the activities also serve students living in the “ivory tower” more chances to get in touch with society. From these activities, the participants have to leave the classroom and get to know the society.
All these offer an important means for students to broaden their horizons. By participating in campus activities, they have fulfilled university life and in turn help campus activities to grow and flourish.

1. 什么是“活到老学到老”;
2. 举例说明“活到老学到老”的意义;
3. 作为大学生，我应该怎样做。
正确答案：The famous saying goes that one is never too old to learn. It means learning is not only the business of school children. As long as you want to learn, it’s never too late to start.
There are many examples to show that learning is never too late. Florence Ross, the respectable lady in the passage once I read, earned her doctorate at the age of 82. She did not complain about her age, and she made it!
I am lucky that I can study in college and receive good education now. But it doesn’t mean that my education will come to an end with a college diploma in hand. Many things are awaiting me to learn and to discover. I’ll make learning my life-long pursuit.

Directions: For this part, you are allowed 30 minutes to write a composition titled Private Cars and Public Transport. You should write at least 120 words following the outline given below in Chinese.
1.私家车的优势
2.公共交通的优点
3.你更倾向于选择何种出行方式
参考答案：
Many people appreciate the conveniences and comforts provided by private cars. A private car enables a person to go where he wants, so that he can enjoy his leisure to the full by making trips to the country or seaside on the weekends, without any irritation caused by waiting for buses or trains. Public transport, on the other side, has attractions of its own. People can feel relaxed on a bus or on a subway train, because they don’t have to concentrate on driving. And if they use public transport, they will help to lessen air pollution and traffic jams. Moreover, it costs them less money and means more job opportunities for others. As far as I am concerned, I hate the air pollution and traffic jams caused by cars. So given the chance, I would prefer public transport.

The Best Way to Keep Fit and Healthy A fit and healthy body is the base of wealth and wisdom. Good health enables us to enjoy our life and achieve what we hope for in our career. On the contrary, poor health tends to deprive us of our interest in everything around us. Only by keeping ourselves healthy and strong can we feel energetic and vigorous in studying, working and living a happy life. People aware of the health problems bring up with a lot of ways to keep fit and healthy. However, the best way to keep fit and healthy is to exercise more and eat properly.
Firstly, physical exercise is very crucial in order to keep fit and healthy. In taking part in out-door sports, we are closer to the nature and can take in fresh air. The beauty of nature will keep us clear-headed, which is essential to our health. Secondly, proper nutrition is important for our body, so we have to keep a balanced diet and maintain a regular eating habit. It is important for us to take more fruits and vegetables because they provide vitamins and they help in the process of digestion. At the same time, we should avoid eating too much food rich in sugar and fat.
In conclusion, if we stick to the proper ways of exercise more and eat properly, we’ll lead a healthy life and become as fit as a fiddle.
