For years scientists have been concerned about the effects of air pollution on the earth's natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired,to suffer eye pain, headache and other problems.Some pollutants(污染物)can cause breathing disorders,diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.People began to notice the problem in the early 1970s.It is said that when builders began making houses and offices they did not want to waste energy.To do this,they built buildings that limited the flow of air between inside and outside.They also began using man-made building materials.These materials are now known to let out harmful gases.As the problem became more serious, scientists began searching for a way to deal with it.They discovered a natural pollution control system for building－green plants.Scientists do not really know how plants control air pollution.They believe that a plant's leaves absorb or take in the pollutants.In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots.Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space.Studies of different plants show that each absorbs different chemicals.So the most effective way to clean the air is to use different kinds of plants.Having green plants inside your house can make it a prettier and healthier place.

Botswana lies immediately to the north of South Africa. It is bordered on the north and west by Namibia, on the north and east by Zimbabwe, and is connected by a narrow strip of land on the northern border to Zambia. Its territory consists almost entirely of a broad, flat, arid subtropical plateau(高原), though there are hills in the eastern part of the country.
In the northwest, the Okavango River empties into the Kalahari sands, creating the largest inland river delta in the world. While the Okavango Delta is home to relatively few large animals in comparison to other areas of Botswana, its clear waters and countless small islands are home to a variety of birds, plants, and smaller species of animals.
Nearby is Chobe National Park, a beautiful grassland reserve(保护区) that has gained international fame for its large elephant population. Southeast of Chobe are Botswana's large Makgadikgadi salt pans, home to numbers of blue wildebeest, several antelope species, and those international lovers of salt pans, flamingos(a kind of birds).
Almost the entire remaining portion of the country is covered by the Kalahari Desert--a varied environment of sand and grassland. Although this area of Botswana is where few people live, it is one of the richest wildlife areas in all of Africa.
Botswana's two largest parks, the Central Kalahari Game reserve and Gemsbok National Park, are found in this region.
Botswana's climate can get rather cool, particularly during the dry winter months of June to August when night occasionally brings frost. The rainy summer months (December through March) are best avoided for those interested in enjoying the best game viewing conditions.

The secret of happiness is to spend around ￡2.50 every day on somebody else.
To give a couple of pounds each day rather than to spend it on treats and fashion for yourself is the key to happiness, according to a new study.
Dr Elizabeth Dunn and her colleagues who did a national survey of 630 people in the United States found that people report greater happiness if they spend money more socially. That means spending on gifts for others or on charitable(慈善的) donations rather than spending on themselves.
"We wanted to test our theory that how people spend their money is at least as important as how much money they earn," says Dunn, who reports the work in Science.
The results from all three lines of research are quite the same.
"Regardless of how much income each person made," says Dunn, "those who spent money on others reported greater happiness, while those who spent more on themselves did not."
"Making a modest donation is enough to increase people's happiness" the researchers conclude.
"These findings suggest that a very small change in spending, as little as ￡2.50, may be enough to produce real gains in happiness on a given day," says Dr Dunn.
The researchers call on governments to encourage people to spend more on others to help translate increased national wealth into increased national happiness.
Surveys have also shown that happiness levels have remained almost flat within developed countries even as incomes have increased in recent decades.
65.According to the survey, what kind of people have greater happiness?
A.People who can make enough money.
B.People who can buy whatever they want.
C.People who spend money on treats and fashion for themselves.
D.People who spend a modest amount of money every day on others.
66.The underlined word "flat" probably means______.
A.smooth B.dull C.same D.interesting
67.Which of the following statements is true?
A.Researchers pay no attention to spending on others.
B.The government did much in helping others.
C."Science" in Paragraph 4 is probably a magazine.
D.The survey is very successful.
68.The purpose of the writer is to tell us______.
A.the secret of happiness. B.money spent on friends.
C.link between money and happiness. D.difference between national wealth and happiness.
