CHEMICAL VERSUS ORGANIC FARMING
Chemical pesticides and artificial fertilisers have been in widespread use in farming since the middle of the 20th century. When they were first introduced, many farmers welcomed them as a great way to fight crop disease and increase production. Over time, however, what some scientists have found is that their long-term use can sometimes harm both the land and people’s health.
For example, pesticides can damage the land by killing not only harmful bacteria and insects, but also helpful ones. In addition, these chemicals can stay in the soil and underground water sources for a long time. This affects the crops grown on the land and, in turn, the animals and humans who digest them. Many people worry that these chemicals may make them ill and even cause cancer. In fact, some pesticides like DDT have been prohibited in most countries because of the damage they cause to people and the environment. As for chemical fertilisers, crops grown with them usually grow too fast to be rich in nutrition. They may look beautiful on the outside, but inside there is usually more water than essential minerals, and they often have less flavour as well.
As an alternative, some farmers have switched to organic farming, and many customers have turned to organic food when they shop at the local grocery. Organic farming is simply farming without using any chemicals. Organic farmers focus on keeping their soil rich and free of disease through natural means. For example, many organic farmers use natural waste from animals as fertiliser. This makes the soil in their fields richer in minerals. It also keeps the air, soil, water, and crops free of chemicals.
Organic farmers also use many other methods to produce rich soil. They often change the kind of crop grown in each field every year. For instance, they may grow corn or wheat in a field one year, and then grow beans there the next. Why different crops are grown is because they put important minerals back into the ground, making it ready for the next batch of crops. Organic farmers also plant diverse crops that use different depths of soil to help keep it rich. For example peanuts grow on the ground’s surface, but many other vegetables put down deep roots. The goal of using different organic farming methods is to grow good food while avoiding damage to the environment or to people’s health.
Some people would prefer to stop the use of man-made chemicals in agriculture entirely. What keeps them from doing so is the fact that chemical farming serves the high demand for food around the world. Organic farming is nowhere near able to meet that need. Therefore, there is still a long way to find a suitable solution that puts sufficient food on the dinner table while keeping people and the environment as healthy as possible.

SHOULD WE FIGHT NEW TECHNOLOGY?
This morning, I saw the shocking headline: “Passenger Dies When Car Crashes in Driverless Mode”. In the article, various people said that the public should oppose the idea of developing driverless cars. They said that some advances in technology were unnecessary and could even be dangerous. Hence, we should cease accepting technology just because it is new. The newspaper reported that the car company had already apologised for the accident, but the families of the deceased said it was not enough. Nevertheless, the company still claimed that most people would be travelling in driverless cars one day soon.
On the one hand, there are many different groups of people around the world who live happily in the absence of new technology. Probably the most well known are the Amish, a group of Christians living in rural America. They do not own or drive cars, watch TV, or use the Internet. They have lived mainly as farmers since the 18th century, and they will probably be living the same way in the distant future. They advocate a simple life with an emphasis on hard work, family, and community. They think that is better than caring about luxuries or following the lives of the rich and famous. It could even be argued that the Amish’s quality of life is better since they live in and appreciate the natural environment rather than living in large, polluted cities.
On the other hand, new technology has provided people everywhere with many benefits over the years. For example, the latest weather-tracking computer programmes give people lots of warnings about potential natural disasters, which saves many lives. Moreover, the Internet has made it possible for friends and family to keep in touch easily even if they are on opposite sides of the world. It has also made finding opportunities in life much easier, as it allows people to make larger networks of friends through using social media.
Personally, I have benefited quite a lot from technological advances. I found my career as an AI designer through a social media network. My health monitor, which I wear all the time, has also helped me get into the best shape of my life. Of course, when new technology changes the way we live, it can be a scary prospect. Nevertheless, I will always look on the positive side of change and accept it rather than resist it.
1.What's the main idea of the text?
A.Driverless cars are popular in the world.
B.Most people admire the Amish's happy life with natural environment.
C.The argument about whether advanced technology is beneficial and acceptable to people.
D.New technology has provided people with great benefits everywhere over the years.
2.What can we know about the Amish from the text?
A.They like living in large and polluted cities.
B.They live happily in the presence of new technology.
C.They advocate living a simple life.
D.They appreciate the lives of the rich and famous.
3.What can we infer from the first paragraph?
A.The new technology will be resisted by the public.
B.The technology which is new is sure to be good.
C.The advances in technology will bring us more danger than convenience.
D.The advances in technology may do unexpected harm to us.
4.What's the attitude of the author about new technology?
A.Positive. B.Negative.
C.Critical. D.Unconcerned.
STUDYING ABROAD IS IT A GOOD OR ABAD IDEA?
Dear Editor,
In the past few decades, there has been a dramatic increase in the number of people studying abroad. Although studying abroad can bring great benefits, I think the disadvantages for young people are greater.
To begin with, many students who study abroad face great economic pressure. That means studying abroad is just not possible for everyone. Tuition fees and living expenses are much more expensive than at home and could end up costing most families an arm and a leg. Studying in China is much more convenient and can help save money.
Another important factor to consider is the tremendous pressure that comes with studying abroad. Students must learn how to live in an unfamiliar environment with limited language skills. Some may struggle and suffer from culture shock when learning how to behave in new surroundings. Other students are not mature enough to handle the challenges by themselves and may become depressed. Some students might even encounter problems with personal safety. In addition, different approaches to teaching and learning may come as a shock to many students.
A final point to consider is that while studying abroad does have potential benefits, young people who study in China also have a great future to look forward to! As China has boomed the educational environment has improved significantly, with many great universities now available. They have great facilities and outstanding professors, helping to educate young people who will contribute to the economy and further strengthen our country.
To sum up, one cannot deny the fact that studying abroad has its disadvantages, so when you think about studying abroad you should consider these many factors.
Kind regard,
Wang Li ( mother of twin girls)
Dear Editor,
Is studying abroad a good idea or not? There are certainly disadvantages, but in my opinion, the advantages are much greater. As I always tell my son, there are no great difficulties or a person who is brave, optimistic, and willing to work hard!
The first advantage of studying abroad is personal growth. The education you gain and the experiences you have will change you for the better. For example, you will certainly become more independent because you will have to deal with all kinds of difficulties by yourself. Studying abroad also helps you to gain a global perspective and improve your general competence.
Another advantage is the increased chance for cultural exchange. Chinese students can be seen as cultural envoy promoting friendship between nations. International students in China also bring their colourful cultures here. Cooperating with people from diverse cultural backgrounds helps us view the world from different angles and thus gives us more insight into our own culture.
Finally, studying abroad provides a great opportunity to contribute to the development of our motherland. China’s global outlook, with projects such as the Belt and Road Initiative, has helped us make connections across the world. Therefore, China needs more talented young people with a global perspective who are highly competent with languages have leadership and organisational skills, and have strong cultural awareness. Students who study abroad will develop such skills and abilities, and these in turn will provide them with better career opportunities.
All in all, studying abroad helps to build character and increase people’s understanding ofcultural diversity while strengthening China and building a shared future for all. I think this life-changing experience is certainly worthwhile and I hopemy child will study abroad in the future.
Sincerely yours
Zhang Yi (father of one boy)

Last but not least, compared with those studying abroad, students remaining nationally also have a great future to look forward to with China booming.

写作三:参考范文
Dear Jackson,
I'm more than delighted to share my opinion, which I hope will be of some help to you. Frankly, I hold the view that it is perfectly reasonable to study abroad. The reasons are as follows.
To begin with, exposure to a foreign language setting while we are studying abroad makes the learning process engaging and effective,Moreover ,bathed in a different culture of a foreign country, we can gain great insights into the world because cross-cultural experiences can give us a global perspective. Studying abroad takes us out of our comfort zone and changes us for the better.
All things considered, I hope you can choose to study abroad and start a new life.
Yours
Li Hua

参考范文:
The summer holiday is coming. Our class had a discussion about what to do during the holiday.
Some are in favor of staying at home. They think it's both convenient and comfortable. What's more, they can save money for other purposes. But they will lose the chance of getting to know the outside world. However, others prefer to go out for traveling since it can increase their knowledge and broaden their horizons. But they will spend more money and meet some difficulties while traveling.
In my opinion, it would be much better to stay at home, for I can do what I like, such as reading books, watching TV, and helping my parents with the housework.
