Moods,say the experts,are feelings that are likely to become fixed,having effects on one′s outlook（way of looking at things）for hours,days or even weeks.That′s great if your mood is a pleasant one,but a problem if you are sad,anxious,angry or simply lonely. Perhaps the best way to deal with such moods is to talk them out;sometimes,though,there is no one to listen.Modern pharmacology（药物学）offers a lot tranquilizers（镇定剂）and anti-anxiety drugs.What many people don′t realize,however,is that scientists have discovered the effectiveness of several non-drug methods to make you free from an unwanted mood.These can be just as useful as drugs,and have the added benefit of being nonpoisonous.So next time you feel out of sorts,don′t head for the drug store--try the following method. Of all the mood-changing self-help techniques,aerobic exercise seems to be the best cure for a bad mood."If you could keep the exercise,you′d be in high spirits,"says Kathryn Lance,author of Running for Health and Beauty. Researchers have explained biochemical and various other changes that make exercise compare favorably to drugs as mood-raiser.Physical work such as housework,however,does little.The key is aerobic exercise--running,cycling,walking,swimming,or other repetitive and sustained activities that increase the heart rate and circulation（循环）,and improve the body′s use of oxygen.Do them for at least 20 minutes a time,three to five times a week.Which of the following best describes the organization of this passage?A.An exercise and its importance are explained. B.A problem is examined and solutions are given. C.Two different views of a problem are presented. D.Recent developments in medicine are described.

资料：What if you were told there was a way you may strengthen your cognitive skills and heighten your intelligence, and all you had to do was was learn to strike up basic conversations in another language? It probably sounds great, because if you’re like most you would love to be able to speak a second language. But then, you recall your experience in high school foreign language-boring tote memorization and long hours with little progress-and perhaps it doesn’t sound so good any more. But, what if you were told it would take only 10 days to be on your way to becoming bilingual? Most people recognize the many benefits of learning a foreign language: You can travel to foreign countries and fell comfortable, be a more productive and enticing employee in today’s competitive job market, and immerse yourself in the vast cultures that surround you. But now, the collective evidence from a number of recent studies suggests that the bilingual experience improves the brain’s so-called executive function-a command system that directs the attention processes that we use for planning, solving problems, and performing various other mentally demanding tasks. These processes include the ability to ignore distractions to stay focused, switching attention willfully from one thing to another, and holding information in the mind-like remembering a sequence of directions while driving. Even better, new approaches to learning mean you can learn a new language without the endless repetition, homework, and memorization. One of the most powerful actually trains people to start speaking a new language in as little as 10 days! In fact, it’s so powerful, even the FBI has purchased it!

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.Having two eyes instead of one is particularly useful for______.A.looking over a wide area B.seeing objects far away C.judging distances D.seeing at night

共用题干 Parkinson's Disease1 Parkinson's disease affects the way you move.It happens when there is a problem with certain nerve cells in the brain. Normally , these nerve cells make an important chemical called dopamine（多巴胺）. Dopa-mine sends signals to the part of your brain that controls movement.It lets your muscles move smoothly and do what you want them to do.When you have Parkinson's,these nerve cells break down.Then you no longerhave enough dopamine,and you have trouble moving the way you want to.2 No one knows for sure what makes these nerve cells break down.But scientists are doing a lot of re-search to look for the answer. They are studying many possible causes,including aging and poisons in the en- vironment.Abnormal genes seem to lead to Parkinson's disease in some people.But so far,there is not enough proof to show that it is always inherited.3 Tremor（颤抖）may be the first symptom you notice.It is one of the most common signs of the disease,although not everyone has it.Tremor often starts in just one arm or leg or only on one side of the body.It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or when you are asleep.In time,Parkinson's affects muscles all through your body,so it can lead to problems like trouble swallowing or constipation（便秘）.In the later stages of the disease , a person with Parkinson's may have a fixed or blank expression,trouble speaking,and other problems.Some people also have a decrease in mental skills.4 At this time,there is no cure for Parkinson's disease.But there are several types of medicines that can control the symptoms and make the disease easier to live with.You may not even need treatment if your symptoms are mild.Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life.Your doctor will adjust your medicines as your symptoms get worse.You may need to take several medicines to get the best results.A lot of research is being done to find out__________.A:what affects muscles all through your bodyB:if there isn't enough dopamine in your bodyC:which cannot be cured yetD:which may be the first symptom you noticeE:if you have a fixed or blank expression F: what causes Parkinson's disease
