Priscilla Ouchida’s “energy-efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000, three-bedroom home in California. Tightly sealed to prevent air leas, the house was equipped with small double-paned windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.

Eperts finally traced the cause of her illness. The level of formaldehyde（甲醛）gas in her itchen was twice the maimum allowed by federal standards for chemical worers. The source of the gas? Her new itchen cupboards and wall-to-wall carpeting.

The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”

The problem appears to be more troublesome in newly constructed homes rather than old ones. Bac in the days when energy was cheap, home builders didn’t worry much about unsealed cracs. Because of such leas, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom build up to dangerous levels. 28. It can be learned from the passage that the Ouchidas’ house _______. A. is well worth the money spent on its construction B. is almost perfect from the point of energy conservation C. failed to meet energy conservation standards D. was designed and constructed in a scientific way 29. What made the Ouchidas’ new house a horrible dream? A. Lac of fresh air.

B. Poor quality of building materials. C. Gas leaage in the itchen. D. The newly painted walls

30. Why were cracs in old houses not a big concern? A. Because indoor cleanness was not emphasied. B. Because they were technically unavoidable.

C. Because environmental protection was more important. D. Because energy used to be inepensive.

31. This passage is most probably taen from an article entitled “_______”. A. Energy Conservation B. Houses Building Crisis C. Air Pollution Indoors D. Traps in Building Construction

Millions of people visit Yosemite National Par every year to see the tall waterfalls and mountains. The mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure(基础设施) that must be maintained .

Unfortunately, these systems are starting to brea down. It’s not just in Yosemite but in national pars around the nation. Yosemite is thirty years old according to Dennis Galvin, a National Par Service worer. The par is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the par to deal with.

Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Par Service had to send water trucs to provide water for the visitors. Last month pipes almost broe again and roads had to be closed for a while.

Why hasn’t the National Par Service ept up the par repairs? There is a lac of money. The United States has 378 monuments, pars, and wilderness areas. Between three and four billion dollars are needed for repairs.

Yosemite is one national par that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the par worers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road wor was damaging the Merced River that runs through the par.

A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded par.

32．According to the tet, the mountains in Yosemite loo splendid when they are appreciated from _____.

A．the bottom of the valleys C．the side of the mountains

B．the top of the mountains D．the edge of the valleys

33．National pars lie Yosemite in the U.S. find it increasingly difficult to meet the need of visitors because

_____.

A．their transport management needs improving B．they spend too much on their service systems C．their service systems frequently go out of order D．they need help from environmental organiations 34．The main problem of Yosemite National Par is its _____.

A．rundown water pipes B．over crowdedness C．lac of money D．narrow roads

35．According to the tet, the Sierra Club is most liely to be _____.

A．an environmental group B．an information center C．a travel service D．a law firm

第二节（共5小题；每小题2分，满分10分）

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Every living thing has genes. Genes carry information. 36 They mae sure that humans give

birth to humans and cows give birth to cows. However, genetic engineers tae genes from one species— for eample, a snae, and transfer them to another — for eample, corn. 37 Such new life forms have been described, by some scientists as a real-life Franenstein.

Genetic engineers put duc genes into chicen to mae the chicens bigger. They put hormones(激素) into cows to mae them produce more mil. They put genes from flowers into beans and from fish into tomatoes. 38 It just maes them easier and faster for the farmer to grow.

The effects of genetic engineering on the natural world may be disastrous. The engineers may create strange life beings or monsters that we cannot control. 39 They’ll have to find one, fight for one, or ill for one. It may be your land they fight for, or you that they ill. Moreover, the effects of these eperiments can often be cruel. In America, pigs were given human genes to mae them bigger and less fatty. The eperiment failed. The pigs became very ill and began to lose their eyesight.

We would all lie a better, healthier and longer life, and genetic engineering might give us this. On the other hand, it may be a dangerous eperiment with nature. In the story of Franenstein, the doctor created such a terrible and dangerous monster that he had to destroy it. 40 A. B. C. D. E. F. G.

The information tells us what to do or what not to do.

We must mae sure that this tale remains a story —— and no more than that. This doesn’t mae them cheaper, tastier, or healthier. The new life forms have no natural habitat or home. Then they feed the tomatoes to the fish. In this way, a new life form is created.

They are passed on from generation to generation.
