AA test to tell if you are at risk from Alzheimer's disease (阿尔茨海默氏病) and dozens of other conditions goes on sale in Britain today costing ￡125.The test uses a saliva sample to provide more than 100 pieces of genetic information including whether users are more likely than normal to suffer Parkinson's disease (帕金森病), some cancers or baldness.It can also predict whether they like coffee or hate Brussels sprouts (甘蓝), which type of exercise is likely to suit them best and give information about a person's ancestry (家族)．The test, already available in the US, is being marketed online by 23andMe, a firm part­funded by Google.A customer spits into a tube, seals it and sends it back to 23andMe's labs for analysis. Four to six weeks later, they receive a detailed report in the post written in everyday language.It will tell them, for example, whether their risk of Alzheimer's disease is higher or lower than average. 23andMe —run by Anne Wojcicki, wife of Google co­founder Sergey Brin — says its mission is to ensure that individuals can personally access, understand and benefit from the human genome (基因组)．It says that armed with the information, people can take better care of their health. For instance, the print­out may give someone the impetus (动力) they need to give up smoking or it could mean they receive regular health checks so that an illness can be caught — and treated early.Genetic tests are already available in Britain but generally provide less informationand are more expensive.1．A test to tell if you are at risk from some diseases ________．A．costs ￡125 every dayB．costs about ￡125C．is of little useD．can help sick people recover2．What does the test make use of to provide genetic information?A．The blood in a person's brain.B．The liquid produced in a person's mouth.C．The skin in a person's breast.D．A person's hair.3．Which of the following is TRUE according to the passage?A．23andMe depends on Google financially.B．23andMe is run by Sergey Brin and his wife.C．Sergey Brin founded Google on his own.D．23andMe is popular now.BThere are three reasons why I don't think that we are ready for cloning. Firstly, we don't know exactly what the consequences of cloning would be. For example, if scientists cloned a man, they might know what he would look like, but they wouldn't know his quality. What would happen if scientists cloned another Hitler or others like him? Do you really think we would survive if this became a reality?Secondly, cloning raises many ethical questions. Look back at the cloned man that has been presented and ask yourself these questions：“Do you really think that he would be a man？”“Who would be responsible for him？”“Do you think he should have the same rights as we have？”I don't think that we can answer these questions now.Lastly, we don't know exactly what the meaning of life is. In my opinion, creating life is the duty of nature, and we must not interfere (干预) with that taskbecause we can't understand the extremely complicated relationships among lives that are defined by nature. Usually these relationships are extremely complex. Sometimes, they seem to be so untouchable that they cannot be changed. From my point of view, we have to look at the natural environment around us. We can see that an ecosystem (生态系统) is made up of a lot of different kinds of life, and each life has its own function within the system. If we disturb that, I think it could lead to our extinction (灭绝)． Even though cloning may have a lot of benefits for humans, I think we should stop cloning because we do not understand it and can't control all of its effects. Maybe in the future, we will be ready to do it, but that time has not yet arrived.4．According to the author, we are not ready for cloning because ________．A．two or more people may have the same appearanceB．scientists are not sure about the personalities of the cloned peopleC．people may not function properly if there are more cloned human beingsD．cloning has not been permitted by the government5．In the third argument the author fears that we will ________ if we create life at will.A．change the natural environment around usB．disturb the ecosystem in natureC．suffer from overpopulationD．accelerate the extinction of animals6．According to the passage, what's the author's attitude towards cloning?A．Positive. B．Critical.C．Indifferent. D．Supportive.7．Which of the following would be the best title for the passage?A．To Clone or NotB．Why Should We Stop Cloning?C．Scientific Research on CloningD．The Advantages and Disadvantages of CloningCI grew up in an area where the natural disaster I was really concerned about wasearthquakes.Besides the fire drills (演习) we had each year at school, we also had earthquake drills. Luckily, there are a few things we can do to prepare for an earthquake.At home, I think we can fasten heavy objects to our walls. We can buy hooks at our local hardware store. When we fasten them to the walls, we should make sure we follow the instructions.When we put objects on shelves, we should make sure they are not heavy or that they cannot hurt somebody when they fall off. This is especially important in bedrooms, as when we are awakened due to an earthquake, our reaction time may be slow. We will want to make sure that we don't have objects that will fall directly on to the bed.For homes with children, I think parents should teach them what to do during an earthquake. Parents should show them how to get under a table during a quake. Another safe place is an inside doorframe. Parents should teach children not to go near glass or other unsafe areas during the quake. I think they should also teach children what to do if they are ever trapped after an earthquake.If we are in a structure, which has suffered considerable damage, I think we should try to move outside after the quake. As we go outside, we should make sure that we are aware of fallen power lines and other dangers. Broken gas mains are another serious danger after a quake.This is an emergency where it is important to have a family's emergency action plan in place.Most likely a family will not be together during an earthquake. If each one can remember what they are supposed to do in this situation, then they will have an easier time finding and picking up each other.8．We learn that in the area where the author grew up, ________．A．wild fires break out frequentlyB．people are not afraid of earthquakesC．earthquakes are very likely to occurD．many kinds of natural disasters take place9．Which of the following is NOT mentioned in the text?A．Fastening heavy objects to the walls.B．Building strong houses for earthquakes.C．Avoiding putting heavy things on shelves.D．Getting out of a damaged building quickly.10．What does the author think of staying inside a doorframe during an earthquake?A．It's challenging. B．It's deadly.C．It's safe. D．It's a bit risky.11．The last paragraph mainly shows the importance of ________．A．staying together as a family in an earthquakeB．having a family's emergency action plan in placeC．finding and picking up each other after an earthquakeD．staying calm and knowing what to do in an earthquakeDScientists say sea levels are rising and will continue to do so into the future. Coastal communities around the world are already experiencing the influence of rising seas. Many cities and towns are taking steps to deal with this new reality.Photographers have taken pictures to document those efforts. Their photos are part of an exhibit called “Sink or Swim: Designing for a Sea Cha nge”. It can be seen at the Aquarium of the Pacific, in Long Beach, California. Disastrous storms and floods could be a new reality around the world. That is the opinion of oceanographer Jerry Schubel. He is president of the Aquarium of the Pacific. He said, “Global climate change is resulting in rising seas, coastal flooding and increasingly powerful storms.”A video produced by the aquarium shows how water levels are rising. It_also_shows_how_low­lying_places_that_flood_historically_are_at_the_highest_risk. Dan Cayan studies weather conditions for the Scripps Institution of Oceanography at the University of California, San Diego. He says sea levels are rising at a higher rate now than a few years ago.Scientists estimate that, by the end of the century, sea levels around the world could rise by more than a meter and could continue to rise. Mr Cayan says heat­trapping greenhouse gases are causing temperatures to rise. According to him, as the climate warms, the potential for releasing stored water on Earth, largely in Greenland, Antarctica,holds a lot of potential sea level rise in the future.Scientists say city planners in coastal communities must continue to come up with new ways to adapt to rising seas. They say this can be done through futuristic buildings, roads and other infrastructure.12．We can learn from Paragraph 1 that now many coastal communities ________．A．don't know they are already at great riskB．face problems caused by rising sea levelsC．have been completely destroyed by floodsD．have moved away because of rising sea levels13．In the opinion of Jerry Schubel, ________．A．flooding is the most common in coastal communitiesB．the world is ready for disastrous storms and floodsC．not all powerful storms are caused by climate changeD．there'll be more disastrous storms and floods in the future14．The underlined sentence in Paragraph 3 means such places ________．A．do not experience as many floods as beforeB．can be very easily affected by sea level changeC．experience higher sea levels than all other placesD．will experience the most various natural disasters15．Which of the following is NOT mentioned in Paragraph 4?A．What causes sea levels to rise.B．Where a lot of water is stored now.C．How much sea levels will rise by 2100.D．How to stop stored water from getting released.Ⅱ.任务型阅读(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。
