Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has.
You cannot change your cycle, but you can learn to make your life fit it better. “Habits can help,” Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point.
Get off to a slow start which saves your energy. Get up with a lazy yawn(哈欠) and stretch(伸展). Sit on the edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying them out the night before.
小题1:Dr. Cleiman did not explain in the passage ___________.
| A．how people can make their life fit their cycle |
| B．whether everyone has a daily cycle or not |
| C．why people have their energy cycle at different times |
| D．what will happen in the family if the couple fail to realize which cycle each member has |
| A．Either of them gets up late in the morning. |
| B．Husbands and wives have different cycles of energy. |
| C．Either of them wants to change the cycle of the other’s. |
| D．They do not know which cycle they themselves have. |
| A．one works better at one’s peak energy point |
| B．if you know your cycle you can change it to fit your life. |
| C．whenever you feel hot, your energy cycle reaches the highest |
| D．your energy cycle must be in the morning if you can get up early |
| A．Getting up late. |
| B．Jumping out of bed as quickly as possible. |
| C．Looking for clean clothes. |
| D．Sitting for a while before getting out of bed. |

Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.
One such bird, a warbler(鸣禽) , had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the direction of the make-be-live stars caused a change in the direction of his flight. Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their main means of navigation (导航). What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark to see these, the warblers circle helplessly, unable to get their direction.
小题1:The reasons why birds don’t get lost on migratory flights__________.
| A．have been known to scientists for many years |
| B．are known by everyone |
| C．have only recently been discovered |
| D．will probably remain a mystery |
| A．from North America to South America |
| B．using what is apparently an inborn navigational ability |
| C．only once during their lifetime |
| D．when they are freed from their cages |
| A．an artificial star | B．some landmarks |
| C．their inborn ability | D．A and B |
| A．discover workable answers to universal questions by studying particular cases(特别案例) |
| B．jump to conclusions |
| C．find a law and then investigate（调查） |
| D．are disappointed by the habits of animals |
For the last few years, the genetic advances in the fast developing field of biotechnology have provided material for all kinds of work, but the developments of modern science in unlocking the secrets of human genetic code have opened a world of possibilities for human health, as well as for the population imagination.
While European and Japanese researchers are making rapid progress in decoding human DNA, the leading organization for genetic research in the Untied States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet terrible diseases, and making progress toward separating the genes that show a sign of breast cancer(乳腺癌)or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.
小题1:Why did the scientists work so hard at mapping the human genome?
| A．Because the human genome can destroy many illnesses. |
| B．Because the human genome’s completion can help to get rid of many diseases. |
| C．Because they wanted to be better known than others. |
| D．Because the Human Genome Project can provided a lot of chances of work. |
| A．Japan | B．Germany |
| C．The United States | D．China |
| A．If the genes can be found, scientists can study many new ways to cure illnesses. |
| B．The United States began genetic research early in the 19th century. |
| C．Many medical companies show great interest in drawing the human genome map. |
| D．The scientists have made great progress in connecting some genes with the cancers. |
| A．The great human genome. | B．The discovery of genes. |
| C．Unlocking the genetic code. | D．Genes and scientists. |

People sometimes make a cheetah a leopard(美洲豹)because they both have spots, but in fact they are very different. A leopard is far heavier and more powerful, but also much slower. The cheetah’s spots cover most of its body except for its stomach and throat. The cheetah’s tail has spots and these become rings at the end of the tail.
An adult cheetah weighs between 35-65 kilograms and is about 80 centimeters high at the shoulder. The cheetah’s head is quite small and the eyes are quite high up. A black line runs from each eye down to its mouth and makes it look a little sad. It has high shoulders that help it to walk so gracefully.
Cheetahs are very fast but they are not very strong. They are not good fighters and will run away rather than fight another animal to protect their food. If they make a kill, it is sometimes taken away from them by stronger animals such as lions and leopard. These animals will kill their young if they get the chance. The cheetah is not a threat to humans at all. It will not attack humans and prefers to stay away from occupied areas.
小题1:Many people know that the cheetah________
| A．is a fast runner |
| B．runs faster than any other animal on land |
| C．runs as fast as it can |
| D．is very fast for periods of time |
| A．has spots all over its body including its tail |
| B．has spots on its stomach and throat |
| C．does not have spots on its stomach and throat |
| D．has spots everywhere except for its stomach and throat |
| A．they can quickly run away |
| B．they are very fast runners |
| C．They want to protect their young |
| D．They are poor fighters |
After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy are also phasing out nuclear power. But France and the United States remain staunch supporters of atomic energy. In fact, almost 80% of France’s electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”
Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power doesn’t create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain’s chief scientific adviser (John Beddington) supports this view. He recently said that the world doesn’t have the luxury of ignoring nuclear energy.
Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they’re expensive; and right now, they require a lot of investment. This higher cost of using “green energy” is usually passed onto the consumer. So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of particular concern while the world economy is in such bad shape.
The main argument against nuclear energy is that it isn’t safe. For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.
The nuclear energy issue is very complex. And it doesn’t look like it’ll be resolved anytime soon. As a Japanese commentator recently said, “it’s been a bad year for the ‘nuclear village’, but I don’t think they’re down and out yet.” The battle continues.
小题1:Which of the following may NOT be the advantage of nuclear energy over other energy sources?
| A．Nuclear energy doesn’t produce any greenhouse gases. |
| B．Nuclear energy can help prevent the climate damage. |
| C．Nuclear energy is more environmental-friendly than other green energy sources. |
| D．Nuclear energy can save the consumers some money, compared to other renewable energies. |
| A．The fact that many people prefer to use the green energy sources while unwilling to pay higher bill. |
| B．The cost of using renewable sources |
| C．The fact that the nuclear power is cheaper. |
| D．The investment of renewable energy sources |
| A．the Japanese commentator is positive about the future of nuclear energy |
| B．the nuclear energy issue will be soon settled |
| C．a battle will break out in the future |
| D．Japan is considering to build a nuclear village in the future |
| A．To highlight the danger of using nuclear energy. |
| B．To introduce some serious nuclear disasters. |
| C．To show the argument between nuclear supporters and protesters. |
| D．To give some advice on how to use nuclear energy safely. |
