1、s skin! In fact, scientists have noticed that heavily striped zebras have 5. 4 lower skin temperature than other animals without stripes in the same area. Some scientists believe that stripes may be an adaptation by zebras to defend themselves from the horseflies that follow zebras. The cooler tempe

2、rature theory holds merit here too, since disease-carrying flies like horseflies like it hot, Flies also dont like landing on striped surfaces. There also have been many other theories that have been suggested for why zebras have stripes. Some explanations are very common. One of them is that stripe

3、s may help zebras hide in grass especially from lions. Lions are color blind and even if they are not far away they may see stripes as grey and be confused by them. Whats more, zebras are a large group of animals living together. When a number of zebra stand or move together, stripes may confuse lio

6、es keep away from zebrasC. Why zebras have strips D. How stripes keep a zebra coolPassage 2 We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people think that craft（工艺, 手艺） no longer exists. One of the ways these people wrongly support t

7、heir view is by pointing to 100-year-old homes which are still solid, and arguing that it is the craftsmanship that is responsible for their durability（牢圈）. Homes in those days were well-built, they say No doubt these homes were well-built, but what these people have done is to mix up the quality of

8、 material used in the house with the quality of the craftsmanship. Homes today could be built to last just as long as those old homes if people were willing or able to pay the price. For example, most people can no longer afford solid oak （橡树） stairways, although they were once fairly common in olde

9、r homes. Nor can they afford the high labor cost of employing a carpenter to build the stairway. Yet if someone can pay the high cost, there are still plenty of carpenters around able to make those stairways. And not only would these carpenters know how to build them, they would probably do a better

10、 job than carpenters of old. One thing the modern carpenter has which enables him to do a better job is much more advanced tools. Such tools as laser beams and power planes help them lay out a house better and make more precision cuts on the wood. Also, it is not uncommon say more to find carpenters

11、 with college degrees and carpenters with a solid knowledge of mathematics, which would enable them to deal with more difficult house designs. The problem of modern quality, then, really boils down to the problem of material, for the modern carpenter is just as able to produce craftsmanship as the c

The underlined phrase boils down to can be replaced by A. reduces by boiling B. makes shorterC. results in D. lies in5. What would be the best title for the text?A. Is Craft Dead? B. Craft, Back to L

15、ife? C. History of Craftsmanship D. Carpenter Today and YesterdayPassage 3 The days of staring attentively at the computer screen pretending to be interested in an assignment even though you are bored out of your mind may soon be coming to an end. Thats because if Dr. Harry Witchel has his way, comp

16、uters of the future will be able to detect （察觉） boredom and even react to it real-time. But before you get concerned, the machine is not reading your mind. It is just keeping track of the constant involuntary movements that people exhibit when in front of a computer or even a television. These are n

17、ot the bigger instrumental actions like moving a mouse or using the remote, but subtle barely noticeable movements like scratching or stretching. Witchel says the level of movement is directly relative to how absorbed the person is in what he/she is reading or watchingthe higher the interest level,

18、the lesser the movement! To test the theory Witchel and his team invited 27 people and exposed them to a variety of digital content for three minutes at a time. The activities ranged from playing online games to reading documents like the EU banking regulations that most people would find boring. A

19、video motion tracker monitored their movements as they powered through each assignment. Just as the researchers had suspected, the involuntary actions decreased surprisingly, by as much as 42%, when the subjects were totally absorbed in what they were reading or seeing. Fortunately, the scientists a

20、re not planning to use the findings that were published in the online Journal to create machines that report students who are not focusing at school. Instead, they believe that combining the motion detecting technology into future computers will help enhance （加强） the digital learning experience. The

21、 scientists say that being able to measure the students interest level, will enable educators to adjust the materials real-time and re-engage the student. Witchel also believes that the technology can provide filmmakers with honest audience opinions and in the future, also be used in developing more

22、 understanding companion robots. 1. Dr. Harry Witchel wants future computers to have the competence to _ . A. sense when users feel tired and less absorbed. B. record how long people surf on the Internet. C. help educators to prepare teaching materials. D. read the peoples mind in front of a compute

23、r. 2. What can we infer from the text? _ A. The machine will be used to detect whether the students are focusing at school. B. Subjects will make fewer unconscious movements if they are concentrated. C. Future computers are intended to cure adolescents of their network addiction. D. Most people thin

24、k banking documents boring because they are of little value. 3. What may be the best title for the text? _ A. Being Exposed to Computers All Day Long Makes You Bored. B. Scientists are Developing a More Advanced Computer Now. C. Computers of the Future May be Able to Detect Boredom. D. The Future Ma

25、chine is Helpful to Teachers And Students. Passage 4Escaping predators （食肉动物）, digestion and other animal activitiesincluding those of humansrequire oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal. In the past decade ocean oxygen level

26、s have taken a divean alarming trend that is linked to climate change, says Andreas Oschlies, an oceanographer at the Helmholtz Center for Ocean Research in Germany, whose team tracks ocean oxygen levels worldwide. “We were surprised by the intensity of the changes we saw, how rapidly oxygen is goin

27、g down in the ocean and how large the effects on marine ecosystems are,” he says. It is no surprise to scientists that warming oceans are losing oxygen, but the scale of the drop calls for urgent attention. Oxygen levels in some tropical （热带的） regions have dropped by an astonishing 40 percent in the

28、 last 50 years, some recent studies reveal. Levels have dropped less significantly elsewhere, with an average loss of 2 percent globally. A warming ocean loses oxygen for two reasons: First, the warmer a liquid becomes, the less gas it can hold. That is why carbonated drinks go flat faster when left

29、 in the sun. Second, as polar sea ice melts, it forms a layer of water above colder, more salty sea waters. This process creates a sort of lid that can keep currents from mixing surface water down to deeper depths. And because all oxygen enters the surface, less mixing means less of it at depth. Ocean animals large and small, however, respond to even slight changes in oxygen by seeking refuge in higher oxygen zones or by adjusting behavior, Oschlies and others in his field have found. These adjustments can expose animals to new predator
