2、n the pictures sent back by NASAs Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.“If there is life on Mars, there is a good chance youd find it in caves,” said Jut Wynne, one of the researchers who noticed the features while
3、 working on a US Geological Survey Mars Cave Detection Program.Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm,suggesting hot air trapped during
4、the day is flowing out.“I said:Wow, thats a cave. ” Dr. Clarke said excitedly. “People have been looking for these for a long time;now we have found them.”He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold,radiation-soaked(充满辐射的),dry surface.“Tiny drops of
5、water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.The caves probably formed when tube-shaped lava flows(管状岩浆流) spr

10、iends ask you to eat with them. What kind of manners do they want you to have? They want you to give a loud burp（打饱嗝儿）after you finish eating. Burping would show that you like your food. In some countries, if you give a big burp, you are told to say “Excuse me, please”.In many places people like to
11、eat together. But in some parts of Polynesia it is bad manners to be seen eating at all. People show their good manners by turning their backs on others while they eat.What are manners like in an East African town? The people try not to see you. They are being polite. You may see a friend. He may no

16、B,C或D四个选项中，选出最佳选项。Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently its because we have mirror neurons (神经元) in our brains. Put simply, the existence of mirror neurons suggests that every
17、time we see someone else do something, our brains imitate (模仿) it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they
18、 also tell us that there is a biological basis for the way we understand other people. Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror ne
19、urons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: “The hand took hold of the ball”) , the same mirror neurons weretriggered as when the action was actually performed (in this example, actually taking hold of a ball) . A
20、ny problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social diso
21、rders. Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact (互动) . Indeed, it may turn out to be the equivalent (相等物) for neuroscience of what Einsteins theory of relativity was for physics. And the next time you feel the urge to cough
22、 in the cinema when someone else doeswell, perhaps youll understand why. 1. Mirror neurons can explain.A. why we cry when we are hurtB. why we cough when we suffer from a coldC. why we smile when we see someone else smileD. why we yawn when we see someone else stay up late2. The underlined word“trig

We can learn from the passage that mirror neurons.A. relate to human behavior and interactionB. control human physical actions and feelingsC. result in bad behavior and social disordersD. determine our know

25、an they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the bodyand the body from themuntil they can be released at just the right spot. There are lots of ways to trigger (引发) this release，including changing temperature, acidity, and so on. But triggers
26、can come with their own risksburns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining nearinfrared light (NIR, 近红外线) on the drug in the capsule.The idea of using light to liberate the drug in the capsule isnt new. Researchers around the globe
27、 have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV, 紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. N
28、IR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds (化合物) absorb NIR well and go through chemical changes. That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues h
29、ad designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIRabsorbing group called onitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a soso NIR absorber, and it could be poiso
30、nous to cells when it separates from the polymer.So Almutairi and her colleagues reported creating a new material for capsules thats even better. This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive (易反应的) components that make it highly un
31、stable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a lightabsorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two
32、 short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. Whats more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.1. According to the passage, which of the following could be the best trigge
33、r?A. Temperature change. B. NIR light. C. Acidity change. D. UV light.2. Why is ONB unsatisfactory?A. It breaks down when it absorbs NIR light.B. It falls off the polymer and triggers drug release.C. It has not come onto the market up till now.D. It is not effective enough and could be poisonous.3.

But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked hi
37、gh exposure (暴露) to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high leve
38、ls of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好) quality and relatively sa
39、fe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainlymodest compared with other risk factors such as smoking and high blood pressure. However, it is im
40、portant to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health. 1. The text mainly discusses the
41、 relationship between.A. heart problems and air qualityB. heart problems and exercisingC. heart problems and smokingD. heart problems and fatty food2. The underlined word“modest”in Paragraph 3 most probably means.A. relatively highB. extremely low C. relatively lowD. extremely high3. What can we lea
