2、than 100 pieces of genetic information including whether users are more likely than normal to suffer Parkinsons 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

3、 about a persons 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 23andMes labs for analysis. Four to six weeks later, they receive a detailed report in the post written in

4、 everyday language.It will tell them, for example, whether their risk of Alzheimers 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

8、dMe is popular now.B There are three reasons why I dont think that we are ready for cloning. Firstly, we dont 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 wouldnt know his quality. What would happen

9、 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？”“

10、Who would be responsible for him？”“Do you think he should have the same rights as we have？” I dont think that we can answer these questions now. Lastly, we dont 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 task

11、 because we cant 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 arou

12、nd 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

13、because we do not understand it and cant control all of its effects. Maybe in the future, we will be ready to do it, but that time has not yet arrived.4According to the author, we are not ready for cloning because _Atwo or more people may have the same appearanceBscientists are not sure about the pe

14、rsonalities of the cloned peopleCpeople may not function properly if there are more cloned human beingsDcloning has not been permitted by the government5In the third argument the author fears that we will _ if we create life at will.Achange the natural environment around usBdisturb the ecosystem in

15、natureCsuffer from overpopulationDaccelerate the extinction of animals6According to the passage, whats the authors attitude towards cloning?APositive.BCritical.CIndifferent. DSupportive.7Which of the following would be the best title for the passage?ATo Clone or NotBWhy Should We Stop Cloning?CScien

16、tific Research on CloningDThe Advantages and Disadvantages of CloningCI grew up in an area where the natural disaster I was really concerned about was earthquakes.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 prep

17、are 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

18、 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 dont have objects that will fall directly on to the bed. For homes with children, I think parents should teach t

19、hem 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

20、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 afte

21、r a quake. This is an emergency where it is important to have a familys 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 ea

22、ch other.8We learn that in the area where the author grew up, _Awild fires break out frequentlyBpeople are not afraid of earthquakesCearthquakes are very likely to occurDmany kinds of natural disasters take place9Which of the following is NOT mentioned in the text?AFastening heavy objects to the wal

23、ls.BBuilding strong houses for earthquakes.CAvoiding putting heavy things on shelves.DGetting out of a damaged building quickly.10What does the author think of staying inside a doorframe during an earthquake?AIts challenging. BIts deadly.CIts safe. DIts a bit risky.11The last paragraph mainly shows

24、the importance of _Astaying together as a family in an earthquakeBhaving a familys emergency action plan in placeCfinding and picking up each other after an earthquakeDstaying calm and knowing what to do in an earthquakeDScientists say sea levels are rising and will continue to do so into the future

25、. 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 S

26、ea Change”. 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

27、 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

28、 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 gas

29、es 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 n

30、ew ways to adapt to rising seas. They say this can be done through futuristic buildings, roads and other infrastructure.12We can learn from Paragraph 1 that now many coastal communities _Adont know they are already at great riskBface problems caused by rising sea levelsChave been completely destroye

31、d by floodsDhave moved away because of rising sea levels13In the opinion of Jerry Schubel, _Aflooding is the most common in coastal communitiesBthe world is ready for disastrous storms and floodsCnot all powerful storms are caused by climate changeDtherell be more disastrous storms and floods in the

32、 future14The underlined sentence in Paragraph 3 means such places _Ado not experience as many floods as beforeBcan be very easily affected by sea level changeCexperience higher sea levels than all other placesDwill experience the most various natural disasters15Which of the following is NOT mentioned in Paragraph 4?
