课后限时作业(九)[语言知识练]Ⅰ.单句语法填空1．The house __was sought__(seek) through but nothing suspicious was found.2．The mother had the baby __crying__(cry) all the morning.3．I swapped my red scarf __for__ her blue one.4．The librarian took a book __at__ random from the shelf.5．The thief broke in，trying to open the safe，but __in__ vain.6．The citizens opposed __building__(build) such a factory in this area.7．I've just come __across__ a beautiful poem in this book.8．Good health is __fundamental__(fundament) if you want to have a long life.9．You needn't worry—he will make __it__.10．Perhaps you should be more tolerant __of__ your little sister.Ⅱ.课文语法填空Athletic performances have 1.__continually__(continue) improved since the first Olympic Games.However，improvements 2.__have begun__(begin) to slow down recently.While 3.__talking__(talk) about breaking records，we come across the issue of performance－enhancing drugs，4.__which__ are originally developed to help people with illnesses，but they are often used by some athletes to perform 5.__better__(well) than usual.6.__In__ other words，doping is a fundamental form of cheating.Unfortunately，it is difficult to catch athletes 7.__using__(use) illegal drugs.The winners have to be tested 8.__while__ other participants are only tested 9.__at__ random.New drugs are developed all the time and drug tests for sporting events are often one step behind.In the future another issue is gene－therapy.Athletes who have their genes 10.__changed__(change) might perform much better in the match.In today's world，if doping and gene－therapy continue to affect the outcomes of major sporting events，the Olympic spirit will have lost its meaning.[高考题型练]Ⅲ.阅读理解A drug used to treat severe bleeding could save thousands of lives for mothers giving birth.A global trial of the drug found it reduced the risk of bleeding deaths during childbirth by nearly one －third.The study involved 20,000 women in 21 countries, mainly in Africa and Asia.The trial was carried out by London's School of Hygiene and Tropical Medicine.The drug is called tranexamic acid (氨甲环酸)．It is low－cost and researchers said it does not cause serious side effects for mothers or babies.The drug is used to treat mothers for severe bleeding during childbirth, also known as postpartum hemorrhage (产后出血)．It is the leading cause of mothers' death worldwide,according to the World Health Organization.Haleema Shakur is the project director of the trial.She says despite medical advances in many countries, severe bleeding after childbirth remains a big problem in some parts of the world.“It's one of the biggest killers of mothers.In Africa and Asia, about 10 percent of women will end up with severe bleeding.” The drug works by stopping blood clots (血凝块) from breaking down after a mother gives birth.The treatment can prevent the need for doctors to perform surgery to find the source of bleeding.Shakur said the best results were reported when the drug was given to women as soon as possible after childbirth.“The earlier you give it—so within the first three hours of giving birth—the better the effect will be.”The next step will be to get the drug where it is needed and provide training for doctors and nurses on how to use it.During the trial, women were given the drug in a hospital.But researchers are looking for easier ways to administer the drug so it can be more widely used in small clinics and rural areas.语篇导读本文为说明文，介绍了一种能够大大降低产妇产后出血死亡几率的药品——氨甲环酸。

A young man from Spain has come to spend six weeks with us. He is no ordinary young man; he's actually my second cousin, and is here to spend time with this side of the family, and of course, to learn English.Thankfully, he is the same age as my youngest son, and is very fun－loving. I'm sure that he will pick up a lot of English while he plays with my kids. That was actually how I picked up a lot of Spanish when I was a child. My mother would take me to Mallorca in Spain, to spend about amonth in the summers. Because children play so much, and are less inhibited(羞涩的) than adults, they absorb language like little sponges(海绵). Well, that's what happened to me, and I'm very thankful for the experience.So far, we have taken my cousin to Seattle for a couple of days, and down to a local river to look for gold. Today, I plan on taking him to the museum in the town of Cashmere which is excellent. He will get his first view of native American life, and be able to walk through some of the original pioneer houses of this area. Like most boys who are thirteen, he is very curious and constantly asks questions. Of course, I don't always have the answers! Coming to the U.S. is a big step for him, especially being so young. Mind you, he is a world traveller. His mother is an air hostess and is able to get cheap airline tickets, so they travel internationally all the time. So he is extremely comfortable in airports, and understands the routines of getting from one place to another. I hope that his being here will encourage my children to spend time in Spain, and also become international travelers.语篇导读本文为记叙文。

The computer's job is to fly the plane. The pilot is there to feed the dog. And the dog's job is to bite the pilot if he tries to touch the computer.Handing complex tasks to computers is not new. But recent progress in machine learning, a subfield of artificial intelligence (AI), has enabled computers to handle many problems which were previously beyond them. The result has been an AI boom, with computers moving into everything from medical diagnosis and insurance to self－driving cars.There is a problem, though. Machine learning works by giving computers the ability to train themselves, which adapts their programming to the task at hand. People struggle to understand exactly how those self－written programs do what they do. When algorithms(计算机程序) are doing small tasks, such as playing chess or recom mending a film to watch, this “black box”problem can be safely ignored. When they are deciding who gets a loan, or how to drive a car through a crowded city, it is potentially harmful. And when things go wrong, then customers, regulators and the courts will want to know why.For some people this is a reason to hold back AI. France's digital－economy minister, Mounir Mahjoubi, has said that the government should not use any algorithm whose decisions cannot be explained. But that is an overreaction. The difficulties caused by clever computers are not unheard －of. Society already has plenty of experience dealing with problematic black boxes; the most common are called human beings, who can't even figure out what's going on in a brain. In response to the weakness in humans, society has evolved(逐步形成) a series of workable coping mechanisms, called laws, rules and regulations. Many of these can be applied to machines as well.Humans have worked with computers on complex tasks for decades. One lesson from such applications is that, wherever possible, people should supervise(监督) the machines. In that joke, pilots are vital in case something happens that is beyond the scope of artificial intelligence. As computers spread, companies and governments should ensure the first line of defence is a real person who can overrule the algorithms if necessary.语篇导读本文为说明文。
