But Farber is certain he’ll have the last laugh. He’s one of a small but growing number of American veterinarians (兽医) now practicing “holistic” medicine-combining traditional Western treatments with acupuncture, chiropractic (按摩疗法) and herbal medicine.Farber, a graduate of Colorado State University, started out as a more conventional veterinarian. He became interested in alternative treatments 20 years ago when he suffered from terrible back pain. He tried muscle-relaxing drugs but found little relief. Then he tried acupuncture, an ancient Chinese practice, and was amazed that he improved after two or three treatments. What worked on a veterinarian seemed likely to work on his patients. So, after studying the techniques for a couple of years, he began offering them to pets.Leigh Tindale’s dog Charlie had a serious heart condition. After Charlie had a heart attack, Tindale says, she was prepared to put him to sleep, but Farber’s treatments eased her dog’s suffering so much that she was able to keep him alive for an additional five months. And Priscilla Dewing reports that her horse, Nappy, “moves more easily and rides more comfortably” after a chiropractic adjustment.Farber is certain that the holistic approach will grow more popular with time, and if the past is any indication, he may be right: Since 1982, membership in the American Holistic Veterinary Medical Association has grown from 30 to over 700. “Sometimes it surprises me that it works so well,” he says. “I will do anything to help an animal. That’s my job.”4.What do some of Farber’s coworkers think of him?A.He’s odd.B.He’s strict.C.He’s brave.D.He’s rude. 5.Why did Farber decide to try acupuncture on pets?A.He was trained in it at university.B.He was inspired by another veterinarian.C.He benefited from it as a patient.D.He wanted to save money for pet owners. 6.What does paragraph 3 mainly talk about?A.Steps of a chiropractic treatment.B.The complexity of veterinarians’ work.C.Examples of rare animal diseases.D.The effectiveness of holistic medicine. 7.Why does the author mention the American Holistic Veterinary Medical Association?A.To prove Farber’s point.B.To emphasize its importance.C.To praise veterinarians.D.To advocate animal protection.Killer whales are mama’s boys. A son will follow his mother, taking bits of fish and other food, throughout his life, even as his sisters grow up and have babies of their own. This neediness comes at a significant cost to mom, who gives up having additional children to look after her boy, according to a new study.Michael Weiss has observed the mother-son bond in killer whale groups off the Pacific coast of North America. “It’s kind of wild,” says the behavioral ecologist. These animals live for decades, yet even fully grown males “act like little kids around their mom, rolling around and swimming right beside and behind her like they're still babies”.Weiss wanted to know whether these high-maintenance children came at a cost —particularly, whether they hurt a mother’s ability to raise more children. He and colleagues studied 40 years’ worth of data on three Pacific pods (小群动物), social groups typically consisting of a couple dozen killer whale mothers and sons that traveled and hunted fish together. Sure enough, the team found a “huge effect”, Weiss says.In a given year, mothers of sons were less than half as likely to have another baby as were childless females or mothers of daughters. Strikingly, both a 3-year-old son and an 18-year-old son lowered their mom’s chances of having more children, Weiss says.The researchers suggest mom’s favoritism toward her boys developed because of the particular social structure of these pods. When a daughter gives birth, her babies stay in the same group as her and her mom and therefore compete with the rest for food and attention. By contrast, a son doesn’t bring more mouths into the group — he mates with females in passing pods who then go on to raise children in their own social units.His kids are thus “someone else’s problem”, Weiss explains. So, it makes sense for mom to give more energy to him than to his sisters if she wants as many grandchildren as possible with the least competition.The team didn’t establish exactly how sons prevented their mothers from having more babies. Weiss says he hopes to do more research across populations, and in different species of whales. But now, killer whales remain an extreme example of parental care across the animal kingdom. “In other animals,” he says, “at some point, you just stop relying on your mom as much.”8.What can we learn about a mother killer whale’s chance of having more babies?A.It is independent of her son’s age.B.A mother of a son won’t have another baby.C.A mother of daughters has the least chance.D.It changes with the social structure of the pod.9.What can be inferred from the research?A.Male killer wales can’t grow fully.B.Male killer wales are precious in their social structure.C.Baby killer wales live with their grandmother.D.Baby killer wales compete against their father for food.10.Why do mother killer whales favor their boys?A.To increase the pod’s population.B.To compete with other pods.C.To gain support from boys.D.To save food.11.What does Weiss think of the mother-son bond in killer whale groups?A.It is extremely rare in nature.B.It shows that killer whales have feelings.C.It doesn’t exist in other species of whales.D.It slows male killer whales’development.Dumbphones have very limited functions compared to an iPhone. You can only make and receive calls and messages. And, if you are lucky-listen to radio and take very basic photos, but absolutely not connect to the internet or apps.Dumbphones are enjoying a comeback. Google searches for them increased by 89% between 2018 and 2021. Meanwhile, a study said that one in 10 mobile phone users in the UK had a dumbphone. Kaiwei Tang, CEO of Light Phone, a maker of dumbphones said that, surprisingly, the company’s main customers are aged between 25 and 35. He says he expected buyers to be much older.Sandra Wachter, a researcher at Oxford University, says that it’s easy to see why some of us are looking for simpler mobile phones. One can reasonably say that nowadays a smart phone’s ability to connect calls and send messages is almost a side function. Your smart phone is your entertainment centre, your newspaper, your map, your diary, and your wallet. They always want to catch your attention with notices and latest news.“If aliens came to earth they’d think that mobile phones are the creatures controlling human beings,” Mr. Tang says. “It’s not going to stop. Instead, it’s getting worse. Consumers are realizing that something is wrong, and we want to offer a choice.”Last year, Przemek Olejniczak, changed his smartphone for a dumphone at first for its longer-lasting battery. However, he soon realized there were other benefits. “Before I would always be checking, going through the news, or other facts I didn’t need to know,“ he says. ”Now I have more time for my family and myself. And I’m not addicted to liking, sharing, or describing my life to other people. I have more privacy.“Yet back in London, Robin West says that many people are confused by her choice of mobile. “Everyone thinks it’s just a short-term thing. They’re always asking me: ‘So when are yougetting a smartphone? Are you getting one this week?’ ”12.What surprises Kaiwei Tang about dumbphones?A.Few people show interest in them.B.They are coming into fashion again.C.Their buyers are mainly young people.D.Dumbphones are in a wider use than smartphones.13.What does Sandra Wachter think of people’s turning to dumbphones?A.Understandable.B.Unusual.C.Thoughtless.D.Meaningful.14.What does the author mention Robin West in the last paragraph?A.To give suggestions on mobile choice.B.To show public support for dumbphones.C.To make a prediction about the future of dumbphones.D.To introduce a different opinion on using dumbphones.15.Which of the following might be a suitable title for the text?A.Dumbphones are Here to StayB.A Generation Controlled by SmartphonesC.Smartphones: Where are they leading us?D.Another Choice? The Return of DumbphonesIn the 1960s and 1970s, some writers and university professors called themselves “futurists”. These futurists tried to forecast the future. 16 The problem was that none of these futurists were scientists or engineers. So, while they knew the future would have more powerful computers, they had no clue what these computers would look like, what they could do, or what impact they would have on our lives.17 Having said that, we can make some good guesses about future technology by looking at current scientific and technological advances. We can also ask the real experts: the scientists and engineers who are bringing us these advances.Because so much of our daily life will be integrated with computers, virtual reality will become an actual, real reality for many of us. This virtual world will at times seem as real as — ifnot more real than — the actual world around us. Without leaving home, you will be able to take tours of foreign countries, or even get a medical exam by a doctor in another city.18 There is already, for example, technology which will allow blind people to see using cameras and deaf people to hear using microphones that are connected to their brains. Future technology will allow people to defeat all sorts of physical disabilities.Much research is being done to unlock the human mind. Using technology that is being developed now, people in the future may be able to not just read someone else’s mind, but also record their thoughts like one would record a movie. 19 For example, robot hands are being developed for people who have no hands. These artificial hands are connected to a person’s nerves so that the person’s brain tells the hands what to do.As a result of such advances, in the future, some people who are badly injured may become more robot than human. 20We should all eagerly view the future as a great adventure — a new world waiting to be explored. Who knows exactly what we will find?A.Speaking of medicine, people with brain injuries will be able to find new hope.B.That is, their brains will control their robotic body parts so they can live their lives normally. C.Only a few of their predictions were right, and all of them missed the computer revolution. D.Artificial hands are made stronger and faster than human ones and work very well. E.Some other research involves using robotic technology to replace human functions.F.Many new parts will be made to replace broken human body ones.G.This should make us hesitate before we try to predict the future.二、完形填空For most of us, running a marathon is hard enough. Spanish athlete Eric Domingo Roldan is a man who did not think running a marathon was enough of a 21 . Instead, on November 8, 2021, he attempted to 22 his mum in the Barcelona Marathon.Completing the race was not 23 for him. To make things even 24 , he wanted to break the world record for “the fastest marathoner pushing a wheelchair (轮椅)”. Such a 25 was difficult to achieve, but Eric had a special 26 . He wanted to develop 27and educate people about multiple sclerosis (多发性硬化症), the disease his mother had dealt with for more than 17 years.Their first attempt was 28 in the Seville Marathon back in 2020. But instead of 29 , they trained harder and Eric promised to 30 in 2021. The conditions were 31 this time. Eric was in his home city, so he made a strong 32 . Then he hit halfway in 1 hour 26 minutes, well on track for the record. “I was feeling 33 from the first kilometer until the last, as my mum never stopped 34 and supporting other runners, and that was the best part of running together,” he shared. “To cross that line meant we did what we 35 after going through the hardest time of our lives.”21.A.benefit B.chance C.risk D.challenge 22.A.amaze B.push C.honor D.respect 23.A.possible B.important C.enough D.helpful 24.A.harder B.worse C.clearer D.faster 25.A.standard B.position C.purpose D.goal 26.A.problem B.reason C.result D.personality 27.A.fitness B.fairness C.awareness D.business 28.A.unsuccessful B.incomplete C.unnecessary D.impracticable 29.A.standing by B.carrying on C.falling behind D.giving up 30.A.recover B.return C.relieve D.reply 31.A.similar B.difficult C.favourable D.unknown 32.A.start B.change C.decision D.connection 33.A.nervous B.concerned C.calm D.happy 34.A.asking B.cheering C.passing D.reminding 35.A.needed B.liked C.promised D.suggested三、语法填空阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
