共用题干 Clinical Trials1 Many clinical trials are done to see if a new drug or device is safe and effective for people to use .Sometimes clinical trials are used to study different ways to use the standard treatments so they will be more effective,easier to use,and/or decrease side effects. Sometimes,studies are done to learn how to best use the treatment in a different group, such as children,in whom the treatment was not previously tested.2 It is important to test drugs and medical products in the people they are meant to help,It is also important to conduct research in a variety of people because different people mayrespond differently to treatments.Some people participate in clinical trials because they have exhausted standard treatment options.Other people participate in trials because they want to contribute to the advancement of medical knowledge.3 The FDA（食品及药物管理局）works to protect participants in clinical trials and to ensure that people have reliable information as they decide whether to join a clinical trial. Although efforts are made to control the risks to clinical trial participants,some risks may be unavoidable because of the uncertainty inherent（内在的）in medical research studies involving new medical treatments.4 People should learn as much as possible about the clinical trials that interest them.They should also feel comfortable discussing their questions and concerns with members of thehealth care team. Prospective（预期的）participants should understand what happens during the trial,the type of health care they will receive,and any costs to them.Anyone considering a clinical trial should also know that there are benefits and risks associated with participating. Reliable information should be available to_________.A: for some patientsB: before participationC: in humansD:medical knowledgeE: during the trialF: candidates for clinical trials

共用题干 Stomach UlcerStomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the population will develop an ulcer at some time in their lives.So a possible cure is good news for many people.Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in the stomach then increase the pain of an ulcer. How does a person know he or she has an ulcer? Doctors say most people with ulcers feel a burning pain in their chests or stomachs.This pain is often called heartburn.It usually happens before eating or during the night. It causes some people to lose their desire to eat,or they are unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H Pilorie.H Pilorie bacteria are what make stomach produce extra stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health expertssay the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also believe curing ulcers will reduce the number of people who develop stomach cancer. The number of people with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.Doctors say a person is more likely to get an ulcer if someone in his or her family has had one.In fact a person with the family history of ulcers is three times more likely to get one than other people.There are ways people can protect themselves from developing an ulcer.

资料：When we see well，we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are. People who are near-sighted can only see things that are very close to their eyes，Everything else seems blurry（=unclear）.Many people who do a lot of work，such as writing，reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away，but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading，they must get glasses，too. Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This，too，can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now，however，it is possible to operate on the cataracts and remove them. Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself，look at an object out of one eye；Then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.People who suffer from astigmatism have______.A.a difficulty that can be corrected by an operation B.eyes that are not exactly the right shape C.an eye difficulty that cannot be corrected by glasses D.one eye bigger than the other
