Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates(气候), where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional (传统的), people often suffer less from problem such as heart disease.
Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can slao happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.Why do people feel sleepy in the early afternoon according to the text?

One day a mime(哑剧演员) is visiting the zoo and wants to make some money as a street performer. As soon as he starts to draw a crowd, a zookeeper drags him into his office. The zookeeper explains that the zoo’s most popular attraction, a gorilla(大猩猩), has died suddenly and the keeper fears that attendance at the zoo will fall off. He offers the mime a job to dress up as the gorilla. The mime accepts.
The next morning the mime puts on the gorilla suit and enters the cage before the crowd comes. He soon discovers he can sleep all as he likes, play and make fun of the people and he draws bigger crowds than he ever did as a mime — the job he likes but loses.
However, with days going by, he begins to notice that the people are paying more attention to the lion in the cage next to his. Not wanting to lose the attention of his audience(观众), he climbs to the top of his cage, crawls across a partition(隔墙), and dangles(悬挂) from the top to the lion’s cage. The lion gets angry at this. The scene is afuel to the crowd.
At the end of the day he is given a pay raise for being such a good attraction. Well, this continues for some time. The crowds grow larger, and the mime’s pay keeps going up.
Then one day when he is dangling over the lion he slips and falls. The mime is terrified(吓坏). He starts screaming, “Help me!”, but the lion is quick.

Most people regard zoos as safe places for animals, where struggles such as difficulty finding food and avoiding predators（捕食性动物） don't exist. Without such problems, animals in zoos should live to a ripe old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often develop diseases, joint problems and behavior changes. Sometimes, they even become unable to have babies.
To learn more about how captivity(监禁) affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos.
The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts（同类事物） who died of natural causes lived an average of 56 years——more than three times as long.
Scientists don't yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity(肥胖) may be to blame. Zoo elephants don't get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups.
Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive.
The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn't appear to be the case with elephants. The text tells us that zoo elephants are different from other zoo animals because they________
| A．develop health problems. |
| B．1ive to a ripe old age. |
| C．are not afraid of predators. |
| D．have difficulty eating food. |
What do the scientists find in their research?
| A．Female elephants live longer than male elephants. |
| B．Female zoo elephants die earlier than their wild counterparts. |
| C．Female zoo elephants live longer than their wild counterparts. |
| D．Both elephants in zoos and those in the wild live in large herds. |
Which of the following does the author suggest in the last paragraph?
| A．Zoo-born elephants should be attended more carefully |
| B．Elephants are no longer an endangered species. |
| C．It may not be a wise policy to keep elephants in the zoo. |
| D．Zoos should keep more animals except elephants. |
Which of the following can be the best title?
| A．Comparison between two species of elephants |
| B．Longer lives for wild elephants |
| C．Female elephants suffer from poor health. |
| D．Longer lives for zoo animals. |
The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse.
Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer.
What made us feel relieved is that there’s growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. To do this they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases.
Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone’s delight, they discovered a natural pollution control system for building—green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant’s leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try?Which of the following statements is TRUR?
| A．Outside air pollution is more harmful than the air inside. |
| B．Scientists have discovered how plants control air pollution |
| C．Indoor air pollution may cause diseases including cancer. |
| D．Only large plants can absorb harmful gases indoors. |
According to scientists, some kind of indoor pollution can be found in ________.
| A．every old building |
| B．every modern house |
| C．all kinds of houses |
| D．all kinds of offices |
What does the underlined part “To do this” refer to in Para3?
| A．To build houses and offices |
| B．To limit the air flow inside |
| C．To use man-made materials |
| D．In order not to waste energy |
The reason why we should use different kinds of plants to clean the air is that ___.
| A．plants can drive out all kinds of pollutants indoors |
| B．plants can absorb different harmful indoor chemical |
| C．plants can take in all pollutants inside and outside |
| D．plants may give out more oxygen than people need |

Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education—to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all.
However, many students won’t do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either.
Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules.
In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.Open education allows the students to_________________.
| A．grow as the educated |
| B．be responsible for their life |
| C．discover subjects outside class |
| D．develop their own interests |
Open education may be a good idea for the students who __________.
