Many different tribes live in the Ituri rain forest of Africa, but the Pygmies are the most unusual. Most of the men are not much more than four feet tall. They weigh only about eighty pounds. The women are even smaller and thinner. But in spite of the fact that they are small, these people are perfectly formed men and women.
It is an exciting experience to visit a Pygmy encampment for the first time. Before you go, you must send word ahead that you are coming. Some friendly native or trader must take the message to the Tiki-Tikis. Otherwise the whole tribe will disappear into the depths of the jungle long before you have come close enough to be welcomed.
The great Ituri rain forest seems cut off from the rest of the earth. There are living, dead, and dying trees on every side. Except where a clearing has been burned and chopped out, a man may live his whole life in the Ituri and never see farther than twenty yards.
It takes sharp eyes to discover the almost hidden path to the Pygmy camp. The path is no wider than a small man’s foot. No sound breaks the silence in this part of the forest. There are no signs of people.
The stranger must walk carefully. What appears to be a bent branch may prove to be a deadly snake. A spotted gold patch of sunlight may be a crouching leopard(豹).
Even the Pygmy camp comes as a surprise. The leafy shelters in which the little people live are hardly three feet high. They look so much like the surrounding undergrowth that they might easily be passed by. These houses contain no furniture of any sort. The beds are merely plantain leaves spread out on the earth floor. There are no cooking pots: food is eaten raw or smoked over a fire. Spears, bows and arrows are the only possessions of these people. When the tribe moves to a new camp there is nothing to carry except these weapons and babies too small to walk.
【小题1】According to the passage, we can conclude _____.

A．are unwilling to communicate with people outside

B．are very cruel and they will kill you with the spears

C．are friendly to the tourists visiting them for the first time

D．move so fast and often that can’t be caught up with easily

As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.
Wash Your Hands
And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
Get Enough Sleep
This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
Keep Hydrated
Drink enough water each day to clear poisonous matter from your system and keep up good moisture（湿度）production in your body.
Eat Immune-Improving Foods
Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陈代谢）, make you feel inactive, and weaken your immune
system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
—————————————？
Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
Avoid Contact with Sick People
If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
Know When to Get Help
A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.
【小题1】To fight A/H1N1 infection, it’s helpful for us to_______ .

Rabbits are easy to raise. They are clean and quiet. They don’t need a lot of room. And it costs a small amount of money to feed them, but you can get a big return.
One male and two females will produce as many as fifty more rabbits in a year. That is enough to provide enough meat for a family. Rabbit meat is high in protein and low in fat.
You don’t have to be a farmer to raise rabbits. You can raise them in the city.
Rabbit houses are easy to make with wood and wire. They don’t have to be very big. But each rabbit must have its own little room in the house. This is very important. Each room should be about 75 centimeters wide, 60 centimeters high and one meter deep.
Fencing is used for the sides and floor of the rabbit house. The holes in the wire fencing should be about one centimeter square. Waste from the animals will drop through the holes. This keeps the rabbit house clean and dry.
Rabbits need a lot of fresh air and sunlight. Cover the sides of the rabbit house only to protect it from rain.
Rabbits eat mostly grass and leaves. Hang feeding containers on the outside of the house to let the rabbits eat whenever they want. They simply pull the grass and leaves through the holes in the fence.
Each room should have fresh water. The water containers should be heavy so the rabbit cannot turn them over. Or you can tie the containers to the fence.
One month after mating(交配), female rabbits give birth to about eight babies. In two months, a baby rabbit should weigh about two kilograms. This is big enough to make a meal for a small family.
Rabbits are also valuable for their fur. It takes time, skill and money to prepare the fur and skin for use. If you have only a few rabbits, it probably would be best to let a tanner(制革工) prepare the fur for you. Skill is also needed to remove the fur from the rabbit.
But rabbits do not have to be dead to be valuable. Many people enjoy keeping rabbits as friendly pets. And rabbit waste makes an excellent fertilizer(肥料). It can be mixed directly into the soil to improve the growth of vegetables, trees, and flowering plants.
【小题1】The text is written mainly_______.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling．Recycling in the home is very important of course．However, being forced to recycle often means we already have more material than we need．We are dealing with the results of that over–consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place．
The total amount of packaging has increased by 12% between 1999 and 2005．It now makes up a third of a typical household’s waste in the UK．In many supermarkets nowadays food items are packaged twice with plastic and cardboard．
Too much packaging is doing serious damage to the environment．The UK, for example, is running out of it for burying this unnecessary waste．If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect．Recycling helps, but the process itself uses energy．The solution is not to produce such items in the first place．Food waste is a serious problem, too．Too many supermarkets encourage customers to buy more than they need．However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example．
But this is not just about supermarkets．It is about all of us．We have learned to associate packaging with quality．We have learned to think that something unpackaged is of poor quality．This is especially true of food．But it is also applied to a wide range of consumer products, which often have far more packaging than necessary．
There are signs of hope．As more of us recycle, we are beginning to realize just how much unnecessary materials are collected．We need to face the wastefulness of our consumer culture, but we have a mountain to climb．
【小题1】What does the underlined phrase “that over-consumption” refer to?

Algae(水藻) are very simple plants. They grow in fresh water or salty water. Seaweed is algae that grow in salty water. Seaweed is red or brown in color. The Japanese people use these plants from the sea in many ways. From it, they make a food called Kombu. Kombu is seaweed that has been dried, cooked and pressed together. Then it is dried again and cut into long pieces. The Japanese eat a lot of Kombu and like it very much.
Japanese farmers often use seaweed as fertilizer. It makes their plants grow better. Many farmers also find seaweed makes a fine food for their animals.
From seaweed the Japanese also get iodine(碘), which they sell to other countries. Iodine is used in many ways all over the world. It is used in making medicine. It is added to the salt we use at the table. Scientists even use one form of iodine to “ seed clouds” when they want rain to fall.
【小题1】 Kombu is a kind of ____ according to the text.

Experts say the American state of Hawaii has been invaded (入侵)by a small frog called the coqui (ko--kee). There may be millions of the small frogs in Hawaii. However, they do not belong there. They are normally found in the southeastern United States. The coqui frogs are harming Hawaii’s environment. And the extremely loud noise they make is causing problems for Hawaiian citizens and visitors.
The coqui invaders arrived in Hawaii about ten years ago. They were believed to have been brought in accidentally in shipments of plants from Florida. Their number has sharply increased. They have quickly spread around the Hawaii Islands hidden in plants.
The coqui is a brown frog about five centimeters long. During the day, the frogs hide in wet protected areas, such as under plant leaves. At night, the frogs move onto trees to feed, call to females and mates. The call of the male coqui sounds like. Ko kee! Ko kee!
In the southeastern United States, local people celebrate coqui frogs. But in Hawaii, the foreign frog has been considered as a harmful animal. The coqui frogs are a major danger to Hawaii’s environmental system. The frogs eat thousands of insects (昆虫)every night. These insects are important for the reproduction of plants. The insects also are important food for Hawaii’s native rare birds. The frogs also are affecting the tourism industry in Hawaii. Increasing numbers of hotels, visitors and local people have been annoyed by the loud calls made by male coqui frogs to female frogs. At night, the noise often makes it difficult for people to sleep.
The frogs do not have any natural enemies in Hawaii to reduce their population size. The warm weather permits them to lay eggs all year long. There are many efforts in Hawaii designed to stop the spread of the coqui. It is a crime to transport ,sell or release(释放)the frogs there.
The Hawaii Department of Agriculture is trying to find an effective chemical that can be safely used to kill the frogs. For now, the frogs may only be caught by hand. The Hawaii Department of Agriculture says the greatest danger to the economy and environment of the state is from harmful species, like the coqui.
【小题1】The statement that can best summarize the main idea of the passage is         .

Which gender is the most talkative? No matter what you answer, you are partially right.
A recent Gallup Poll showed that both men and women believe that women possess the gift of talking and some even believe women are biologically built for conversation, but all of that is challenged in a research published in the November issue of Personality and Social Psychology Review.
In a recent research by Campbell Leaper and Melanie Ayres, they collected all of the available evidence from decades of scientific study and systematically combined the findings into an overall picture of the differences between men and women regarding talkativeness.
They found a small but reliable tendency(趋势) for men to be more talkative than women in certain cases, such as when they were conversing with their wives or with strangers. Women talked more to their children and to their college classmates.
The type of speech was also explored in the research. The researchers discovered that, with strangers, women were generally more talkative when it came to using speech to ensure her connection to the listener, while men’s speech focused more on an attempt to influence the listener. With close friends and family, however, there was very little difference between genders in the amount of speech.

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous（灾难的）. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
【小题1】As pointed out at the beginning of the passage, people used to think that air pollution ______.

A．caused widespread damage in the countryside

B．affected the entire eastern half of the United States

C．almost brought worldwide effect

D．existed merely in urban and industrial areas
