Medical developments and discoveries often provide the best things for controversies (争论).This is because whenever a new discovery or theory is proposed, there is always disagreement. Only via objective scientific evidence can such arguments be cleared. But, as is often the case, a clear solution is not instantly found. However, once the technology catches up with the area of the discovery, it shows exactly how valid the theory is. Since this is a slow process and can take years, the development of controversies is unavoidable.
Over the years, various such controversies have been developed, examined, and either rejected, or proved right for the good of mankind. Now read the following examples.
Firstly, cancer was largely regarded as an incurable disease, since its exact cause was unknown. Later, professors and doctors came up with various theories regarding the cause. Some claimed it was the result of chemical processes, while others believed it was a sort of poison. After a few decades, a doctor proposed that cancer was caused by the inhalation (吸入) of pollutants, in the form of smoke, gas, etc. His claim was rejected by many researchers and doctors. However, due to various scientific studies, this claim is now clearly common knowledge, though there may be other causes.
Many people worry that the use of cell phones can cause cancer. Recent studies suggest that this common threat is actually quite true. Numerous studies indicate that the long usage of cell phones (at least an hour per day) increases the risk of developing brain tumors.
After the discovery of X-rays, they were widely used, from doctors' clinics to shoe stores to see the fit of shoes. People thought they could offer the benefit of visualizing the skeleton (骨骼) of a person without causing any danger to the person. However, in 1956, the National Academy of Science reported the harmful effects of these rays on the human body, and the practice was then given up. Presently, we all know that exposure to X-rays may lead to radiation poisoning, tissue breakdown, and even death.
1.What may stop the scientific evidence of a theory being found quickly?
A.Agreement among scientists. B.The lack of professional researchers.
C.Technological limitations. D.The lack of motivation for investigating.
2.Different scientific studies have proved that _________.
A.cancer is not an incurable disease. B.cancer is caused by chemical processes.
C.air pollution is becoming more serious. D.air pollution is one of the causes of cancer.
3.How is the passage mainly developed?

Zheng Pengyu: Interest is the best teacher. Classrooms that weren’t fixed could give students the chance to explore their interests. At the same time, they would be able to learn on their own because they would have to make their own decisions. All in all, the new system would be a good chance to inspire students’ passion for studying.
Sun Yao: Despite its benefits, I’m worried about whether the new system would work. Going to different classrooms would take up a big part of our break time and we would have less time to relax after class. Also, not all schools could offer so many diversified classes.
Shi Zhenghan: I support s
tudents learning in different classes. It would solve the problem of some students thinking the classes are too easy while some think they are too difficult. Teachers could also teach more effectively. What’s more, friendships built while in different classes might be a pleasant surprise.Zhou Qingqing: In my opinion, studying in different classrooms might affect students’ psychological (心理的) development. They might find it difficult to develop deep and strong friendships with other students if they had to change classrooms constantly. They would also lose their sense of belonging to a certain class.
Hu Qile: I applaud the idea. It would help teachers set up special teaching plans for different classes. For students, making choices by themselves could encourage them to be responsible. Changing classrooms could also help relive the boredom of doing the same dull routine (惯例) every day.
Wang Xiaoqian: The new system might help with students’ individual development, but I still prefer the current system. Studying in one fixed classroom, students with different academic levels can help each other. Spending your senior middle school years with the same classmates is an unforgettable experience.1.According to Sun Yao, which of the following sentences is TRUE?
A. The new system will work if great measures are taken.
B. All the schools can’t afford so many diversified classes.
C
. Students will have more time to relax.D. He supports the system because of its benefits.
2.Sun Yao holds a(n) _____ attitude towards the new system.
A. optimistic B. doubtful C. negative D. neutral
3.What is the passage about?
A. Schools should offer diversified classes to students.
B. Students find it difficult to develop friendship.
C. Different opinions about changing classroom.
D. Changing classroom can help with students’ individual development.
4.Which of the following can best replace the word “applaud” in paragraph 5?

Weather experts said this year could be one of the strongest EL Nino events in recorded history. El Nino means severe weather conditions in parts of the world. In eastern Africa, for example, Kenya and Uganda are preparing for possible flooding. Yet South Africa and Malawi are already dealing with extremely dry weather.
El Nino is Spanish for “the child”. It usually begins in December, near the celebration of the birth of Jesus Christ. In fact, the weather event was named in his honor. El Nino develops when winds off the west coast of South America weaken. This permits warm water in the western Pacific to expand toward the east and the Americas. At the same time, clouds and rain over the warm water move east, too. El Nio conditions normally appear only about twice every 10 years. Usually, El Nino conditions continue for about 12 to 18 months. They bring warm weather to some areas. These areas become wetter than normal, while others become drier.
The United Nations Children’s Fund warns that many people are at risk from hunger, disease and water shortages resulting from El Nino. In the east and southern Africa up to 11 million children could be affected. East African countries usually experience heavy rainfall during the El Nino. Southern Africa usually has little rainfall which may lead to wildfires or drought(干旱).
Weather changes caused by El Nino depend on the strength of the condition. In the early 1980s, strong El Nino was linked to dry weather in Australia and Asia, rain and flooding in South America and high temperatures in many parts of the U.S. The years later, smaller El Nino caused trouble in parts of the U.S. It caused severe floods in the Southeast and the Middle West. Tom Di Leberto is a meteorologist(气象学家) at the National Oceanic and Atmospheric Administration in Washington, D.C. He said this year could be the third strongest El Nino on record. But we will not know for sure until all the weather records are examined.

A. many countries are preparing for the coming floods
B. Africa will probably suffer a lot form this year’s El Nino
C. this year could be one of the strongest El Nino on record

A. what El Nino actually means

C. when El Nino will occur next time
D. why El Nino causes weather changes
3.Which of the following countries often suffers from flooding caused by El Nino?
A. Kenya B. Malawi

4.The author mentioned the 1980s’ El Nino and the 1990s’ El Nino to ______ .
A. explain why so many countries were affected by El Nino
B. prove weather changes caused by El Nino depend on its strength

D. show scientists doubt whether this year will have the strongest El Nino
