Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.
The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.
In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms—the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already taken them away? The huge stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?
Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.
In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.

In a recent study, researchers have estimated the energy required to produce bottled water, including the energy required to manufacture plastic, make the plastic into bottles, process the water, fill and seal the bottles, transport the bottles, and chill the bottles for use. Combining all the energy input totals for treatment and distribution, researchers found that producing bottled water requires between 5.6 and 10.2 million joules(焦耳) of energy per liter, depending on transportation factors. That's up to 2, 000 times the energy required to produce tap water.
To break down the energy requirements, researchers found that producing the plastic bottles and transporting the bottles greatly dominated(控制) the energy input. Although some companies are experimenting with producing lightweight bottles or using recycled materials, the researchers calculated that the manufacturing cost is about 4 million joules of energy per plastic bottle weighing 38 grams, and the cap weighing 2 grams.
“Our previous work had suggested that bottled water production was an energy intensive process, but we were surprised to see the results, ” the researchers said.
Transportation costs vary depending on the distance and mode of transport and both factors depend on the type of bottled water. There are two main kinds of bottled water in the US:” spring water” which comes from an underground spring and “purified water”,which is city tap water that has received further treatment. For purified water distributed locally by truck within Los Angeles, the total transportation energy is about 1.4 million joules per liter. In the second situation, spring water shipped from Fiji (such as Fiji Spring Water) across the Pacific to Los Angeles, and then delivered locally by truck requires about 4 million joules per liter for transportation. For the spring water, the transportation energy equaled (in the case of Fiji) the energy required to produce the bottle.
With this data, the researchers hope that future studies will have the ability to make specific estimates for different situations, and possibly find ways to cut energy costs.
【小题1】From the first Paragraph we can know that the energy required to ______.
| A．produce bottled water includes the energy required to drink it |
| B．distribute bottled water includes the energy for producing the bottles |
| C．distribute bottled water is much smaller than the energy for treating it |
| D．produce bottled water is much smaller than the energy for producing tap water |
| A．to fill tap water into the plastic bottles directly |
| B．to replace the plastic bottles with metal containers |
| C．to produce lightweight bottles with recycled materials |
| D．to use bicycles to transport and deliver bottled water locally |
| A．Treatment of bottled water needs no energy input at all. |
| B．Bottled water production is an energy intensive process. |
| C．Transportation of bottled water takes up the most energy input. |
| D．Production of the plastic bottles greatly dominated the energy input. |
| A．there are two main kinds of bottled water in the US |
| B．world consumption of bottled water has been increasing |
| C．transportation costs have something to do with the mode of transport |
| D．bottled water produced in Spring is more expensive than purified water |
| A．To help consumers themselves make more environmentally sustainable choices. |
| B．To advise the government to take severe measures to stop producing bottled water. |
| C．To urge the consumers to drink tap water instead of bottled water for the sake of the earth. |
| D．To try the best to find ways to produce bottled water cheaply and quickly for the companies. |

We can stay young forever. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging.
His solution is a herbal medicine to slow the process of aging.
Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has
taken a hint from its aging process. It is responsible for the level of activity that the human bodies go through Studies conducted by Dr.Shen show that herbal medicine based on the shen system slow the the ancient Chinese medicine system called “shen”.
According to Shen, it is the kidney（肾脏）which adjusts the functioning of the body as well as aging process, says a report in The Telegraph newspaper.
We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness in general, and wrinkles, among others. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance called Fas. Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young?
This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.
【小题1】How did Dr. Shen find the solution to the problem of aging?
| A．By studying Western medicine. |
| B．By learning traditional Chinese medicine. |
| C．By combining both Western and Chinese medicine. |
| D．By doing research on both Western and Chinese people. |
| A．Medical treatment. | B．People’s good kidney. |
| C．Level of people’s activity. | D．Positive life attitude. |
| A．their bodies produce T-cells |
| B．their bodies are unable to fight diseases |
| C．they have reduced strength, loss of hair |
| D．they become weaker and weaker |
| A．producing more low calorie food allows people to keep young |
| B．the more Chinese herbal medicine people drink, the better for health |
| C．people should try to quicken the production of T-cells in the body |
| D．it remains unknown how effective Dr. Shen’s herbal medicine is |

If a diver surfaces too quickly, he may suffer the bends. Nitrogen (氮) dissolved (溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡) accumulate in a joint, is sharp pain and a bent body — thus the name. If the bubbles form in his lungs or brain, the consequence can be death.
Other air-breathing animals also suffer this decompression (减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs (鱼龙). That these ancient sea-animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil(化石)bones that have caved in on themselves are thus a sign that the animal once had the bends.
Bruce Rothschild of the University of Kansas knew all this when he began a suty of ichthyosaurs bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompession over the 150 milllion years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Trassic period and from the later Jurassic and Cretaceous periods.
When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before the died, but not a single Trassic specimen showed evidence of that sort of injury.
If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly — and, most strangly, they lost it afterwards. But that is not what Dr Rothchild thinks happened. He suspects it was evolution in other animals that caused the change.
Whales that suffer the bends often do so because they have sufaced to escape a predator (捕食动物) such as a large shark. One of the features of the Jurassia oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaurs lunches. Trassic oceans, by contrast, were mercifully shark-and crocodile-free. In the Trassic, then, ichthyosaurs were top of the food chain. In the Jurrasic and Cretaceous, they were prey (猎物) as well as predator —and often had to make a speedy exit as a result.
【小题1】Which of the following is a typical symptom of the bends?
| A．A twisted body. |
| B．A gradual decrease in blood supply. |
| C．A sudden release of nitrogen in blood. |
| D．A drop in blood presure. |
| A．how often ichthyosaurs caught the bends |
| B．how ichthyosaurs adapted to decompression |
| C．why ichthyosaurs bent their bodies |
| D．when ichthyosaurs broke their bones |
| A．confirmed his assumption | B．speeded up his research process |
| C．disagreed with his assumption | D．changed his research objectives |
| A．failed to evole an anti-decompression means |
| B．grdually developed measures against the bends |
| C．died out because of large sharks and crocodiles |
| D．evoled an anti-decompression means but soon lost it |

Rae and Bruce Hostetler not only work very hard,they also relax just as well. Numerous vacations help the couple to maintain their health and emotional well-being一and it’s no surprise to health care professionals.
“Rest, relaxation, and stress reduction are very important for people’s well-being and health. This can be accomplished through daily activities, such as exercise and meditation, but vacation is an important part of this as well,” said primary care physician Natasha Withers from One Medical Group in New York. Withers lists a decreased risk of heart disease and improved reaction time as some of the benefits from taking some time off. “We also know that the mind is very powerful and can help with healing, so a rested, relaxed mind is able to help the body heal better,” said Withers.
Psychologists confirm the value of vacations for the mind. “The impact that taking a vacation has on one’s mental health is great,” said Francine Lederer, a clinical psychologist in Los Angeles who specializes in stress and relationship management. “Most people have better life perspective and are more motivated to achieve their goals after a vacation, even if it is a 24- hour time-out.” The trips could be good for their health, good for their family and good for their businesses.
The online travel agency Expedia conducted a survey about vacation time in 2010, and according to their data the average American earned 18 vacation days一but only used 14 of them. France topped the list, with the average worker earning 37 vacation days and using all but two of them. Americans’ responses may not be surprising in a culture where long hours on the job often are valued, but that’s not always good for the individual, the family or the employer.
Psychologists have also found that people who don’t take enough time to relax may find it harder to relax in the future. “Without time and opportunity to do this, the nerve connections that produce feelings of calm and peacefulness become weaker, making it actually more difficult to shift into less-stressed states,” Mulhem said.
【小题1】How did the author introduce the topic of the text?
| A．By making comparisons. | B．By giving an example. |
| C．By raising questions. | D．By providing data. |
| A．dislike family gatherings |
| B．have the shortest vacation |
| C．enjoy as many vacations as the French |
| D．think much of spending long hours on the job |
| A．One should never wait to relax. |
| B．Work and rest go against each other. |
| C．Time and opportunity wait for no man. |
| D．A relaxed mind determines everything. |

Monitoring global warming usually requires a Ph. D. and enough maths to glaze your eyes. But that Francisco Lopez and Ruby Nostrant track（记录）what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade.
“We are collecting data because the weather is changing and the plants are blooming,” Ruby explained.
Scores of other students at Borton Primary Magnet School and Sunnyside High School in Tucson are heading outdoors to be part of a new scientific push to figure out how the biological timing of the earth is changing. It’s a research project that the average person, even a kindergartner, can join in.
The National Phenology（生物气候学）Network is calling on volunteers to help track early spring blooms and eventually changes in animals caused by global warming. It’s called Project Budburst. When it was first open to the public last year, thousands of people participated in 26 states.
“All people can contribute to it by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard,” said Phenology Network director Jake Weltzin. He calls the volunteers “citizen-scientists.”
The idea is that tracking flowers blooming—especially lilacs（丁香）; which everyday people have helped track for decades—is fairly simple. The Website http://www.Windows.ucar.edu/ citizen_science/budburst/index.html gives directions on what to look for in different parts of the country.
University of Maryland professor David Inouye said it’s so easy to figure out what’s blooming that a lack of special knowledge isn’t a problem.
University of Arizona ecology graduate student Lisa Benton coordinated（协调）the Tucson high school students as they looked at plants five minutes from their high school. Each student has specific guidelines and she’s been happy so far with the data she is getting. For his part, second-grader Francisco said he had fun helping out.
“I like going out in the desert,” he said. “I want to be an Einstein.”
【小题1】Francisco Lopez and Ruby Nostrant are monitoring global warming by __________.
| A．watching early spring blooms and changes in animals |

| A．the study carried out by students is convincing |
| B．the students still need special training to study climate change |
| C．it is difficult to study climate change |
| D．to figure out what’s blooming needs special knowledge |
| A．Lisa Benton. | B．David Inouye |
| C．Francisco Lopez. | D．Jake Weltzin. |
| A．changes in animals caused by global warming happen earlier than those in plants |
| B．the biological timing of earth is changing because of climate change |
| C．the effect of climate change in Tucson, Arizona can be hardly noticed |
| D．all the plants in Tucson, Arizona are blooming earlier because of climate change |
