For example, some high school and university students in the US often spend many hours as volunteers in hospital or old people's homes. They read books for the people or they just visit them and play games with them or listen to their problems.Other young volunteers go and work in the homes of the sick people. They clean up their houses or do the shopping. For boys who don't have fathers there is an organization called "Big Brothers". University students and other people take these boys to play baseball games and help them get to know things that boys usually learn from their fathers.Each city has a lot of clubs where boys and girls can go to play games or join in other activities. Some of these clubs show movies or have short trips to the mountains, the beaches or the museums. Most of these clubs use a lot of high school and university students as volunteers because they can understand the problems of these boys and girls more easily.Volunteers believe that some of the happiest people in the world are those who help to bring happiness to others.1.What is "Big Brothers"?A.It's a name of a club.B.It's an organization for boys who don't have fathers.C.It's the home for children who have no brothers.D.It's the name of a famous movie.2.Why do most of the clubs use a lot of high school and university students as volunteers?A.Because they can only help the boys.B.Because they are too young to get along well with the children.C.Because they can understand the problems of younger children.D.Because they have more free time.3.What do volunteers believe ?A.The happiest people in the world are those who join some clubs.B.The happiest people in the world are those who are young and healthy.C.The happiest people in the world are those who make themselves happy.D.Bringing happiness to others make them the happiest people in the world.4.What might be the best title for the passage?A.Big Brothers in the US.B.Volunteer Work in the US.C.Clubs in the US.D.Students in the US.9、 It has long been thought that elephants rely on their large ears and bathing in rivers to stay cool in hot climates. New research, however, has showed that the world's largest land animals have a secret trick of controlling their body temperatures.Scientists have long been puzzled by temperature regulation(调节)in elephants. Generally, animals with large bodies tend to hold more heat because, compared to their size, they have a small surface area for heat to escape from. Elephants, with their heavy­weight frames, would appear to be at a disadvantagein the heat of their African and Asian habitats, especially because they have thick fur to protect them from bushes and trees.Scientists thought that these creatures, which weigh up to 13 tons when fully­grown, grow large ears to help them stay cool. The skin on the ears is thinner, so blood which flows into them cools down more easily. But findings by researchers at two universities in Vienna have showed that elephants are also able to cool down by increasing the blood flow to skin patches(斑) in other parts of their bodies.The researchers studied six African elephants at Vienna Zoo as they moved between outdoor and indoor environments to see how the temperature on their skin surface would change. They found up to 15 “hot spots” all over an elephant's body surface, in addition to large patches on the ears. The study shows how these patches expand as the air temperature increases and more blood flows nearer to the skin surface. Other experiments show that elephants in the wild use the same “windows” to control their body temperature.Elephants have two additional ways to stay cool: flapping(拍打)the ears and bathing. Together with these tricks, the skin hot spots allow the animals to keep their body temperature always at about 36 degrees-one degree less than humans.1.What can we know about the elephants?A.They can weigh up to 3 tons when fully?grown.B.They live in cool areas in Africa and Asia.C.They have thick fur to protect them.D.They are afraid of water and rivers.2.The function of the thinner skin on elephants' ears is to________.A.keep sensitive hearingB.help hold more heatC.drive away insectsD.control their body temperature3.The new research________A.studied six Asian elephantsB.proved that scientists' earlier beliefs were totally trueC.aimed to discover the elephants' disadvantagesD.studied elephants in a zoo and in the wild10、Traditionally, patients who want to improve their heart health have received four main suggestions from their doctors: Eat a healthy diet, get more exercise, quit smoking, and enjoy proper amounts of alcohol. Plenty of research backs up these four pieces of advice: Large studies have found that making improvements in these four areas lowers the chance of dying of heart disease by 67 percent.But lately, researchers are starting to recognize that there should be five recommendations on that list, not just four. They’re discovering that getting enough sleep is a powerful health protector as well. When researchers include enough sleep in their studies as a fifth cardio-preventive behavior change, they find that it lowers the chance of dying of heart disease even more: Adding a good seven hours of sleep a night in addition to making positive changes in diet, exercise, smoking, and alcohol intake lowers the chance of dying of heart disease by 83 percent.When that news started coming out, doctors began adding sleep onto their list of recommended health behavior changes. But as an expert in heart disease, I don’t think sleep belongs at the bottom of the li st. I think it should be at the top. I believe that getting enough sleep –at least seven to eight hours per night for most people –is the most important health behavior change you can make to improve the health of your heart and your overall health.S ure, I’d prefer that everyone make all of the big five lifestyle changes, but if I could only choose one, I’d pick sleep because when you are well-rested, you have more power to make the right choices about what you eat and drink, and you have more energy to exercise and kick bad habits such as smoking and overeating. But when you’re exhausted, everything in life is more difficult.1.What does plenty of research show about the 4 common suggestions?A.They should be reconsidered.B.They help improve people’s health.C.They are not as helpful as expected.D.They are the best ways found so far.2.How did the doctors react to the news on sleep?A.They just ignored it.B.They discussed it publicly.C.They thought it made sense.D.They totally changed their mind.3.What does the last paragraph mainly talk about?A.What the importance of a healthy lifestyle is.B.Why different factors need to work together.C.What prevents people from living healthily.D.Why the author makes sleep his No. 1 suggestion.完形填空11、阅读下面短文,从短文后各题所给的四个选项(A、B、C和D)中,选出可以填入空白处的最佳选项。
