As the world population grows, demand for mineral and energy resources climbs. Earth s

cientists must deal with the search for additional supplies of traditional and alternative resources as well as the environmental impact of their use. Resources are commonly divided into two groups. Some are classified as renewable, which means that they can be replenished over relatively short time spans. Common examples are plants and animals for food, natural fibers for clothing, and forest products for paper. Energy from flowing water, wind, and the sun are also considered renewable.英译中

第3题

In the early days of nuclear power, themade money on it. But today opponents have so c

omplicated its development that no nuclear plants have been ordered or built here in 12 years.

The greatest fear of nuclear power opponents has always been a reactor “melt down”. Today, the chances of a meltdown that would threatenUSApublic health are testing new reactors that rely not on human judgment to shut them down but on the laws of nature. Now General Electric is already building two advanced reactors in. But don't expect them even on USA shores unless things change in Washington.

The procedure for licensing nuclear power plants is a bad dream. Any time during, or even after, construction, an objection by any group or individual can bring everything to a halt while the matter is investigated or taken to court. Meanwhile, the builder must add nice, but not necessary improvements, some of which force him to knock down walls and start over. In every case when a plant has been opposed, the Nuclear Regulation Commission has ultimately granted a license to construct or operate. But the victory often costs so much that the utility ends up abandoning the plant anyway.

A case in point is the Shoreham plant onNew York'sLong Island. Shoreham was a virtual twin to the Millstone plant in, both ordered in the mid 60s '. Millstone, complete for $ 101 million, has been generating electricity for two decades. Shoreham, however, was singled out by antinuclear activists who, by sending in endless protests, drove the cost over $5 billion and delayed its use for many years.

Shoreham finally won its operation license. But the plant has never produced a watt power. Governor Mario Cuomo, an opponent of a Shoreharn start up, used his power to force's publicities commission to accept the following settlement: the power company could pass the cost of Shoreham along to its consumers only if it agreed not to operate the plant. Today, a perfectly good facility, capable of servicing hundreds of thousands of homes, sits rusting.

96.The author's attitude towards the development of nuclear power is _____.

A.negative

B.neutral

C.positive

D.questioning

97.What has made the procedure for licensing nuclear plants a bad dream_____

A.The inefficiency of the Nuclear Regulation Commission.

B.The enormous cost of construction and operation.

C.The length of time it takes to make investigations.

D.The objection of the opponents of nuclear power.

98.It can be inferred from Paragraph 2 that _____.

A.there are not enough safety measures in theUSAfor running new nuclear power plants

B.it is not technical difficulties that prevent the building of nuclear power plants in theUSA

C.there are already more nuclear power plants than necessary in theUSA

D.the American government will not allow Japanese nuclear reactors to be installed in theUSA

99.Governor Mario Cuomo's chief intention in proposing the settlement was to _____.

A.stop the Shoreham plant from going into operation

B.urge the power company to further increase its power supply

C.permit the Shoreham plant to operate under certain conditions

D.help the power company to solve its financial problems

100.From which sentence of the article can you see the attitude of the author and that of Governor Mario Cuomo respectively_____

A.the 2nd sentence in the first paragraph, the 3rd sentence in the last paragraph.

B.the last sentence, the last sentence but one

第4题

There is a vital need for national parks.We must have them as places where plants and

animals can be preserved in the natural state for all time.And we need parks as a retreat (休养所) from the crowded bustling life of cities.Our record for conservation (自然资源保护) is poor.Half of the animal species existing at the time of Captain Cooks arrival are now extinct(灭绝).Australia has wildlife (野生生物) that is not found in the native state in any other part of the world.This wildlife is therefore of particular scientific value.In New South Wales, the National Parks and Wildlife Service is responsible for the care of out native plants and animals in their natural environment.One of the aims of this service is to educate people in the need for conservation.The service also provides facilities for recreation (娱乐) in parks and wilderness areas throughout the state.A UNESCO (联合国教科文组织)study stated that a country should strive to retain 5 percent of its land as national parks.Australia at present is below this figure but there is a community awareness of the need to increase it and new areas are being proclaimed almost annually.In the years to come, our national parks will be one of our most valuable assets.As our population grows and our cities become more crowded，parks will become vital as retreats from the pressures of modern urbanized living.

The United Nations declared 2011 to 2012 the Year of the Bat. The campaign was launched

as a way to strengthen efforts for protecting the world's only flying mammal. These creatures can be found in many parts of the world. Bats live in cities, deserts, grasslands and forests.There are over 1,200 bat species.

The smallest bat in the world is from Southeast Asia.This kind of bat measures about 30 millimeters in length. The world's largest bat, the Giant Golden-Crowned Flying Fox, has a wingspan of 1.5 meters.Most bats eat insects,but many feed on fruit or nectar from flowers.

Many people think bats are blind,but this is not true.Many species have very good sight.Most bats communicate and find their way by making"echolocation" (回声定位法 ) noises.They produce high-frequency noises and can estimate the distance of an object by using the sound echoes that bounce back to them. So, while bats may travel in total darkness, they"see"using sound.

Sadly, bats are widely feared and misunderstood. Most bats come out of their shelters only at nightfall. Three bat species feed on blood. Because of these qualities, bats have long been linked in many cultures to death, darkness and blood-drinking.

Yet bats are important for agriculture and our environment. They help pollinate (授粉)plants and spread seeds. They also help control insects. Bats eat huge numbers of insects,including kinds that damage crops.

For example, a brown bat can eat more than 1,000 insects in one hour.Onereport says bats save American farmers billions of dollars every year by reducing crop damage and limiting the need for chemicals that kill insects.

Over one-fifth of all bat species are under threat. They face disease and the human destruction of their natural environments.In some areas, diseases have killed nearly 100% of bat populations.

Teeth have been a part of animals almost from the beginning of animal life. The first

animals to have teeth were fish. These sea creatures lived millions of years ago. They had many finely pointed teeth for grabbing food from the water. They were distant cousins of today’s sharks.The teeth of animals help them do certain jobs or eat certain kinds of foods. Elephants have two large teeth, called tusks, which they use for digging up plants or for fighting. Lions and tigers have long, sharp teeth for tearing apart other animals. Those of horses and cows are short and flat. They are used for grinding plants.People have three main kinds of teeth. They have teeth that cut, teeth that tear, and teeth that grind. When biting into a piece of fruit, people use their cutting teeth. When pulling a piece of meat from a bone, they use their tearing teeth. When nibbling on a fresh carrot, they use their grinding teeth.Every person grows two sets of teeth. The first set often begins to appear when a baby is about six months old. It lasts until the child is about six years old. Then the baby teeth fall out and the second teeth come in. This second set must last for the rest of a person’s life.It is important for people to take care of their teeth. They must eat the right foods. They should brush their teeth properly. Teeth should be checked twice a year by a dentist.
