Television As a Better Source of News Among the three mass media—television, newspaper and radio, I regard television as a better source.
My statement that television is a better source of news is based on the following two reasons. The first reason is that television can report news more quickly. We can get the news at the same time when something is happening or immediately after something happened. While newspapers can only offer the news that happened a day or two days ago. The second reason is that television can report news more vividly and impressively. With sounds and pictures on TV, we can be deeply impressed by the news as if we were personally on the spot. But when we try to get news from the newspaper, we have to concentrate our mind on the lines and use our imaginations to for a concrete image, which is always tiresome and time-consuming. According to the above mentioned reasons; we can easily draw a conclusion that television is really a better source of news.

第三段, 通过比较得出倾向性的结论, 表明作者的态度. Where to Live–in the City or the Country
Many people appreciate the conveniences of the city. The city has better transportation service and health care. City dwellers can easily enjoy themselves in restaurants, department stores and concert halls. They are well-informed about what is going on at home and abroad, and have the access to better education, better jobs and more opportunities for business. But country life is also attractive. With the fresh air, the green trees and the singing birds, country people are close to nature and live a quiet life. They can make friends with simple and honest men or wander about leisurely without any pressure upon their mind.
Both the country and the city, however, have their own disadvantages. In the country, educational facilities, medical services and transportation systems are still not fully developed. And the city also has many problems, such as heavy traffic, air pollution, great noise and poor housing conditions. As far as I’m concerned, I hated the terrible dirt and noise in the city. So, given the chance, I would prefer to live peacefully in the country.
The Main Difference Between Exam-oriented Education and Quality-oriented Education
Education in China used to be exam-oriented one. But with the development of education reform, quality-oriented education is stressed again and again. So there rises a question: what is the main difference between these two?
According to my understanding, exam-oriented education focuses on students’ ability of passing examination of different levels. This education is to test the students command of knowledge they
have obtained from the textbooks. So examination results are the only criterion which is used to evaluate the students whether they are “excellent” ones or “bad” ones. However, quality-oriented
education focuses on students’ various qualities, including academic moral quality, cultural quality, most important, their individual personality and potentialities. The main purpose of this education is to bring students’ practical potentialities into full play. Quality-oriented education can teach students how to face difficulties and solve problems independently.
From the above comparison between exam-oriented education and quality-oriented education, we find that the latter one is superior. So it is time for our universities and colleges to bring quality-oriented education into students’ daily life.
比较一个事物的两个方面的时候也可以用这种模式：

用拓展句加以具体明. (A1A2A3B1B2B3 subject-by-subject pattern) 第三段, 通过比较得出倾向性的结论, 表明优劣或作者态度.

The Advantages and Disadvantages of Air Travel
In the last fifty years, traveling by air has become the most popular form of long-distance journeys. However, there are both positive and negative associated with it.
The first advantage of air travel is that it is quick. For instance, we can fly from Beijing to Guangzhou in less than three hours. The second advantage of traveling by air is that it is convenient. After we have checked in, all we have to do is to get on and sit down. The friendly air stewardess will look after our every need. The third advantage of traveling by air is that it is now relatively cheep, especially for long distance travel. We can fly from Beijing to Guangzhou for only 1200 Yuan.
But on the other hand, traveling by air has its disadvantages. Perhaps the most obvious is the element of danger involved, such as hijackings and crashes. Traveling by air also makes it impossible for us to see many scenic spot on the way to our destination. In addition to the above mentioned, a long distance air travel may make us very tired, both mentally and physically. Many precious days of holiday may be wasted recovering from airsickness.
To conclude, although air travel involves inconvenience and slight risk, I would say that the advantages mentioned above weigh much more than the disadvantages.
Exercise:
With the development of computer, the Internet has become widely used. It is just like information net that has covered the world. Some people worry that it provides too much for people. Write a composition of about 200 words to state your view on this issue.
Does the Internet Provide Too Much for People
When a great deal of information is exchanged on the Internet almost every second, some people worry that it provides too much for people. To know it clearly, we should look at both sides of the Internet.
On one hand, the Internet shows us a closer and wider world than ever before. Just staying at home, we can get all kinds of useful information in any scientific research field whenever we need. Through the Internet, more and more chances are provided to improve our work, enrich our knowledge and help our country to keep up with the others. But on the other hand, the Internet also brings us many troubles. Useless information and games send to us unavoidably. From this angle, we have to say that those people’s complaints are understandable.
Generally speaking, the Internet has played an important role in modern life. It is like a double-edged sword. We should make the best use of one edge, and try not to be hurt by the other one. 模式III

Sharing a Room with a Stranger or Living by Yourself
Nowadays, more and more college students like to live off campus. Some prefer to share a flat with somebody else to divide the rent between them and others prefer to have a flat to themselves. There are always two aspects to one situation. Sharing a flat with somebody else has its advantages and disadvantages.
Study requires peace and quietness. A stranger who shares a room with you may disturb you. Your thoughts can be interrupted by his sudden return, or by asking for a light, or merely by his cough or sneeze. At night, when you want to sleep, he may be tossing in bed, making enough noise to keep you awake. If the stranger is bad-tempered, he may quarrel with you, and yet, you must have patience.
However, there are many positive aspects of sharing a room with a stranger. First, with another person in the room, you will not feel lonely although far way from you home. Second, you can always help each other. Whatever difficulty you are in, you can get a helping hand. If the person you live with is a senior student, you can even get advice from him on your work and study. Third, living with a stranger offers you a chance of learning to get along with people. Since you have to live with a stranger for quite a long period, you will do your best to make friends with him. If you are successful in gaining his trust, you may also be successful in the more complicated and competitive society.
Therefore, I think, sharing a room with a stranger is a good arrangement of living for all the disadvantages. I prefer to share a flat with someone else rather than live alone.
Where to Live– in the City or in the Country
Each year thousands of people rush into big cities. Some come for education, some for shopping and some on business. But most of them, attracted by the job opportunities and modern life, come to stay.
People enjoy city life chiefly for its conveniences. To begin with, the city provides fast transport, with roads and buses leading to every corner. Then, there are department stores and shops all over the city, where you can buy all kinds of goods you want. Besides, hospitals and other services are
all within easy reach. Indeed, whatever your need is, you can easily get what your want.
However, ig cities are confronted with many problems. One is the housing problem. For examples, it is not uncommon for two or even three generations to share an apartment. Another problem is pollution. The air is not clean and the environment is noisy.
In short, the city is only a place for business, to be visited occasionally. It is not an
