AI work with V olunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured,displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2to 3weekold owl. It had already been placed in a carrier for safety.I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable.I placed the chick in the nest, and it quickly calmed down.Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH! The parents had done their duty and would probably continueto do so.1．What is unavoidable in the author's rescue work according to Paragraph 1?A．Efforts made in vain.B．Getting injured in his work.C．Feeling uncertain about his future.D．Creatures forced out of their homes.2．Why was the author called to Muttontown?A．To rescue a woman.B．To take care of a woman.C．To look at a baby owl.D．To cure a young owl.3．What made the chick calm down?A．A new nest. B．Some food.C．A recording. D．Its parents.4．How would the author feel about the outcome of the event?A．It's unexpected. B．It's beautiful.C．It's humorous. D．It's discouraging.答案与解析语篇导读：本文是一篇记叙文，主要介绍了作者救助一只小猫头鹰，给它做新的窝，帮助它回到父母身边的故事。
1．A推理判断题。
根据第一段中的“Trying to help injured,displaced or sick creatures can be heartbreaking；survival is never certain.”可知救助受伤的、流离失所的、生病的动物是令人心碎的，因为我们救助的动物是否能活下去，也就是说我们为救助动物而花费的努力可能会白费，这是不可避免的。
故选A。
2．C推理判断题。
根据第二段中的“She had found a young owl (猫头鹰) on the ground. When I arrived, I saw a 2to 3weekold owl”可知有人给作者打电话是因为有只小猫头鹰掉在地上了，作者赶过去看，文中并没有说小猫头鹰受伤了，作者只是过去看情况，所以D选项错误。
故选C。
3．A细节理解题。
根据第四段中的“I placed the chick in the nest, and it quickly calmed down”可知在作者把猫头鹰放在窝里之后，它很快就安静下来，所以是窝让小猫头鹰安静下来的。
故选A。
4．B观点态度题。
根据前文描述可知作者为小猫头鹰做了窝，并且帮助它找回了它的父母，小猫头鹰父母还为它带回了午餐，作者的救助成功了，说明结局是美好的。
再结合第一段的“However，when it works, it is simply beautiful.”可推测，作者感觉很美好，故选B。
BWhen a leafy plant is under attack, it doesn't sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the airis a mixture of chemicals known as volatile organic compounds, VOCs for short.Scientists have found that all kinds of plants give out VOCs when being attacked .It's a plant's way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the_tables_are_turned. The attacker who was lunching now becomes lunch.In study after study, it appears that these chemical conversations help the neighbors.The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.Does this mean that plants talk to each other? Scientists don't know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn't a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There's a whole lot going on.5．What does a plant do when it is under attack?A．It makes noises.B．It gets help from other plants.C．It stands quietly.D．It sends out certain chemicals.6．What does the author mean by “the tables are turned” in Paragraph 3?A．The attackers get attacked.B．The insects gather under the table.C．The plants get ready to fight back.D．The perfumes attract natural enemies.7．Scientists find from their studies that plants can________．A．predict natural disastersB．protect themselves against insectsC．talk to one another intentionallyD．help their neighbors when necessary8．What can we infer from the last paragraph?A．The world is changing faster than ever.B．People have stronger senses than before.C．The world is more complex than it seems.D．People in Darwin's time were imaginative.答案与解析语篇导读：本文是一篇说明文。

So far seven different kinds of mammals have already been successfully cloned, including sheep, cats and most recently rabbits.Doctors showed their doubt and were strongly opposed although they admitted that human cloning would finally come true unless there was a worldwide ban on the practice.Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology said, “I find it astonis hing that people do this where the result can be foretold that it will not be a normal baby. It is using humans as guinea pigs. It makes people feel sick.”But Ronald Green, director of the Ethics Institute at Darmouth College in the US, said it was unlikely that an eight-week-old pregnancy would lead to a birth.So far all cloned animals have suffered from some different serious disorders, many of them dying soon after their births.Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one.“There are no benefits of cloned human beings, just harm,” said Dr Michael Wilks of the UK.1.What do the underlined words “on the brink of” in the first paragraph most probably mean?A.on the side ofB.on the point ofC.in search ofD.in favour of2.What is the doctors’ general attitude to cloning of humans according to the passage?A.They are against it.B.They support it.C.They pay no attention to it.D.They welcome it.3.What does the under lined word “ban” in the fourth paragraph most probably mean?A.Order that forbids cloning.B.Suggestion on carrying on cloning.C.Anger at cloning.D.Cheer for cloning.4.Which of the following statements is TRUE according to the passage?A.Doctor Severino Antinori is strongly opposed to cloning human beings.B.Up to now, seven kinds of animals have been cloned, including sheep, cats, humans and rabbits.C.Professor Rudolf Jaenisch is carrying on an experiment on cloning an eight-week-old embryo.D.Ronald Green doubts about the future successful birth of so-called cloned embryo.四、语法填空As we all know, cloning is a way of ①__________(make) an exact copy of another animal or plant.

Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn’t have food, water, a phone, or other supplies. He was getting colder by the minute.Nicholas had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use.He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn’t, his body temperature would get very low, which could quickly kill him.Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn’t lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could—he huddled(蜷缩) in his cave and slept.The next day, Nicholas went out to look for help, but he couldn’t find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls’ survival show Man vs. Wild. That's where he learned the tips that saved his life. In each episode(—期节目) of Man vs. Wild. Grylls is abandoned in a wild area and has to find his way out.When Grylls heard about Nicholas' amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.1.What happened to Nicholas one Sunday afternoon?A.He got lost.B.He broke his skis.C.He hurt his eyes.D.He caught a cold.2.How did Nicholas keep himself warm?A.He found a shelter.B.He lighted some branches.C.He kept on skiingD.He built a snow cave.3.On Tuesday, Nicholas _____.A.returned to his shelter safelyB.was saved by a searcherC.got stuck in the snowD.stayed where he was4.Nicholas left Grylls a very deep impression because he _____.A.did the right things in the dangerous situationB.watched Grylls’ TV program regularlyC.created some tips for survivalD.was very hard-working6、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。

The vehicle-named the Transition–has two seats, four wheels and wings that fold up so it can be driven like a car. TheTransition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t help if you’re stuck in traffic. The car needs a runway.Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The govemment has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find redatively easy to meet.1.What is the first paragraph mainly about?A.The basic data of the Transition.B.The advantages of flying cars.C.The potential market for flying cars.D.The designers of the Transition.2.Why is the Transition unlikely to show up in too many driveways?A.It causes traffic jams.B.It is difficult to operate.C.It is very expensive.D.It bums too much fuel.3.What is the government’s attitude to the development of the flying car?A.CautiousB.Favorable.C.Ambiguous.D.Disapproving.4.What is the best title for the text?A.Flying Car at Auto ShowB.The Transition’s Fist FlightC.Pilots’Dream Coming TrueD.Flying Car Closer to Reality四、七选五How to Care for a Pet FishTaking care of a pet is a big responsibility, so you should make sure you learn all about your pet before bringing it home. ①______ That' s because fish can give them a good idea of whether or not they'll be able to take care of a more complicated(复杂的) pet later on.First, choose what types of fish. ②______ They are easier to raise and give you enough experience to take care of fish and their tanks(水箱). Some kinds of fish do not get along with others, so you'll need to choose what kinds to buy.Next, make sure you have all of the necessary supplies. Fish need a fish tank. Make sure it is big enough for the number of fish. Fish tanks need a light and some machines to keep the water clean and at a comfortable temperature. ③______Now you can set up your aquarium(水族馆). Wash sand and decorations( 装饰物) clean and fill the bottom of the tank with them. ④______ Follow the instructions on the heater to heat up the water to the temperature your fish will need. Make sure your light is ready to go, too!⑤______ The pet store keeper can teach you how to make your fish get comfortable before you put them into your aquarium. Once the fish are in the tank, you have to watch them closely to make sure they don't get sick. Feed them in small amounts a few times a day. You will have to change some of the water at least once a week.A. Then, fill the tank with water.B. You are ready to pick up your fish.C. Many kids have fish as their first pet.D.

2019春高中英语人教版选修8练习：Unit 2 Cloning 含解析
Unit 2 Cloning[导语]从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整20年过去了，陈老仍然执着于此。
然而保护大熊猫，究竟要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100，000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.“Those who are against cloning have made their voices heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it is a way to save endangered animals，”Chen said.Some scientists take a different view.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.
