AHail (冰雹) is solid precipitate (沉淀物) that forms within thunderstorms. Hailstones are sometimes found containing sand, leaves, nuts and insects. There are even reports of hail containing small turtles, baby crocodiles and frogs! All of them have been sucked into the storm by tornadoes and subsequently enveloped in ice through repeated updraft currents (上升气流).Hailstones generally begin forming as seeds of small frozen raindrops or soft ice particles known as graupel (雪丸). If graupel falls through the cloud and gets into an updraft part of a thunderstorm, it mixes with water drops and ice particles that will freeze around it as it rises, like layers of an onion. These ice-stones are carried into the tops of the cloud, gaining mass as they rise. Somewhere up there, they become too heavy for the updraft to carry and so fall towards the ground. As they fall, the outside layer melts to aclear layer.Larger hail can fall at a speed of over 100 mph, thus causing damage and injuries to almost anything. Pea to penny-sized hail can cause light damage to trees and vegetation and possibly cause minor injuries to people and animals. Tennis ball to baseball-sized hail is obviously damaging. It can cause severe damage to crops and produce life-threatening injuries to people and animals.Deaths caused by hail are rare in the US with the last known fatality occurring in March 2000 in Lake Worth, Texas. A young man died from head injuries after being stuck by a softball-sized hailstone. Deaths and injuries are more common in other parts of the world where people live in poorly constructed buildings with little protection.If caught in a hailstorm while driving, attempt to stop immediately or pull into a nearby safe place; otherwise, the effect of the hail will be maximized. Try to drive and park the vehicle in the direction of the hail so that it is hitting the front of the vehicle. Windscreens are generally strengthened and can withstand larger impacts than side and back windows. This will lessen any damage from flying glass to both people and equipment in the vehicle.21.What makes some hail contain something unusual?A.Air currents.B.Strong storms.C.Thunderstorms and tornadoes.D.Tornadoes and updraft currents.22.What does Paragraph 2 mainly tell us?A.How hail comes into being.B.What graupel is made up of.C.What different layers of hail look like.D.How graupel mixes with water and ice.23.What's the purpose of the last paragraph?A.To urge people to stay away from hailstorms.B.To warn drivers of the potential dangers during hailstorms.C.To offer guidance to drivers on how to prevent hail damage.D.To advise people to purchase necessary protective equipment.BThe idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play plays an important part in keeping you healthy.Treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.Anyway, adding humor, laughter, and play to our life will influence us mentally, physically and socially and bring us many advantages. So we should make full use of humor, laughter and play to make our life more active, more interesting and happier.24.What does the underlined word “infectious” in Paragraph 2 probably mean?A.Playing an important role.B.Keeping people in high spirits.C.Quickly influencing other people.D.Preventing illness from spreading.25.What can laughter increase according to the author?A.Cognitive ability.B.Good relationships.C.A sense of humor.D.Happiness and trust.26.What does the author think the old should do?A.They should have a good rest.B.They should play like children.C.They should prevent cognitive falling.D.They should take part in physical play.27.Which of the following would be the best title for the text?A.Humor, Laughter and Play for Health.B.Always Keep Our Body Healthy.C.Have an Active and Happy Life.D.Let Our Body and Mind Relax.CPlastic sludge(污泥) and garbage is a disaster for the world’s oceans. A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. “Half of the waste actually sinks to the bottom, and that that remains on the surface actually breaks down.”The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacifc Oceans, home of what some have plastic. What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant.”The pieces of the plastic garbage infect the food chain, sometimes visibly, and more so at the microscopic level, where the plastic particles interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while it acts like magnets(磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues.”To be consumed by other sea life and by people at last.China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters. The United States, although a leader in recycling, is one of the world’s 20 since it produces and consumes so much plastic. There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon(黎巴嫩). But Andersen says there is more that people can do. “Cut back on single-use plastics, straws, plastic cups, plastic water bottles, plastic bags and find alternatives like reusable materials.”She says healthy oceans are essential to our survival.28. What can we learn from the passage?A. There’s all island full of plastic rubbish in the Pacific.B. The bad effect of plastic pollution can’t be seen by eyes.C.

Plastic pollution in the World.B. Plastic pollution—Oceans’ Disaster.C. Ways to solve the problem of plastic pollution to oceans.D. Plastic pollution and our health.DSomething’s happening at the lowes t point on our planet, some 1,388 feet below sea level. The Dead Sea, a salt lake close to Israel, Jordan and the West Bank, is shrinking at an alarming rate — about 3.3 feet per year, according to the environmentalist group EcoPeace Middle East.“It’s not just like one country is punishing the Dead Sea; it’s more like the whole region,”said photographer Moritz Küstner, who visited the area in February to work on his series “The Dying Dead Sea”.The Dead Sea needs water from the other natural sources surrounding it, such as the Jordan River basin. But around the 1960s, the courses of some water sources it relied upon were diverted. Israel, for instance, built a pipeline during that time so it could supply water throughout the country.Mineral extraction(提取) industries are another main reason why the water levels are declining, experts say. The Dead Sea’s minerals have been popular for their medical power and can often be found in cosmetics(化妆品) and other consumer products.And then, of course, there’s the Middle East’s hot, dry climate, which makes it difficult for the lake to refill itself. Last year, Israel and Jordan signed a $ 900 million deal in an effort to stabilize the Dead Sea’s water levels. It involves building a canal from the Red Sea to the Dead Sea which would be able to not only supply water to Israel and Jordan but also to pump much needed water — some 300 million cubic meters annually — into the Dead Sea.“This is the most important and significant agreement since the peace treaty with Jordan (in 1994),”said Silvan Shalom, Israel’s energy and water resources minister at the time. Whether the canal —estimated to take three years to complete — will work out positively and as planned remains to be seen.For now, Küstner shows us that the Dead Sea remains very much a place of interest, with people from all over the world going there to swim in its salty waters.32. How many reasons for the Dead Sea’s shrinking does the author mention in the passage?A. One.B. Two.C. Three.D. Four.33. W hat does the underlined word “diverted” in paragraph 3 mean?A. Switch.B. Improve.C. Accomplish.D. Repair.34. Which of the following statements is TRUE according to the passage?A. The Dead Sea is drying out causing water shortage to humans.B. Küstner visited the Dead Sea to shoot TV series about people’s life.C. The Dead Sea’s minerals have been used in some products.D. The Dead Sea’s water levels have been stabilized by building a canal.35. What is the passage mainly about?A. How the Dead S ea’s water levels’ decline influences human beings.B. How important the Dead Sea is in Israel,Jordan and the West Bank.C. What we should do to save the Dead Sea from being destroyed.D. Why the Dead Sea is dying and the measure taken to save it.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
