There is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, howerer, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast.
Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.
People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.
This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.
What is this passage primarily concerned with？
A．The problems caused by economic growth.
B．The desirability of economic growth.
C．The desire for more material wealth.
D．The limits of economic growth.

Whenever advertisers want you to stop thinking about the product and to start thinking about something bigger, better, or more attractive than the product, they use that very popular word "like". The word "like" is the advertiser’s equivalent of the magician’s use of misdirection. "Like" gets you to ignore the product and concentrate on the claim the advertiser is making about it. "For skin like peaches and cream" claims the ad for a skin cream. What is this ad really claiming？ It doesn’t say this cream will give you peaches-and-cream skin. There is no verb in this claim, so it doesn’t even mention using the product. How is skin ever like "peaches and cream" ？ Remember, ads must be read exactly according to the dictionary definition of words. This ad is making absolutely no promise for this skin cream. If you think this cream will give you soft, smooth, and youthful-looking skin, you are the one who has read the meaning into the ad.
The wine that claims "It’s like taking a trip to France" wants you to think about a romantic evening in Paris as you walk along the street after a wonderful meal in an intimate cart. Of course, you don’t really believe that a wine can take you to France, but the goal of the ad is to get you to think pleasant, romantic thoughts about France and not about how the wine tastes or how expensive it may be. That little word "like" has taken you away from crushed grapes into a world of your own imaginative making. Who knows, maybe the next time you buy wine, you'll think those pleasant thoughts when you see this brand of wine, and you'll buy it.
How about the most famous "like" claim of all, "Winston tastes good like a cigarette should"？ Ignoring the grammatical error here, you might want to know what this claim is saying. Whether a cigarette tastes good or bad is a subjective judgment because what tastes good to one per son may well taste horrible to another. There are many people who say that all cigarettes taste terrible, other people who say only some cigarettes taste all right, and still others who say all cigarettes taste good.
The word "like" in an ad often focuses the consumer’s attention on ______.
A．what the advertiser says about the product
B．what magic the product really possesses
C．why the advertiser promotes the product
D．why the product is as good as promised

In the modern technological world the sea offers many resources to help mankind survive. Resources on land are beginning to grow less. The sea, however, still offers hope to supply many of man’s needs.
The riches of the sea yet to be developed by man ’s technology are impressive. Oil and gas explorations have existed for nearly thirty years. Valuable amounts of minerals such as iron, nickel and copper and so on exist on the ocean floor, ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental peoples.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy such as hydroelectric power.
Technology is enabling man to explore ever deeper under the sea. The new undersea technology is providing divers with diving suits and undersea chambers that are kept at sea level pressure. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. By the year 2000, experts believe that the problems to exploit the food, minerals, and energy sources of the sea will be largely solved.
What is the best title for the passage？
A.Needs of .Man
B.Sources of..Energy
C.Sea Harvest
D.Sea Exploring Technology
According to the author, technology for exploring the sea is important because______.A.man cannot travel farther into space
B.resources on land are running short
C.it’s a lot of fun diving into the sea
D.ancient people used to explore the sea
Why does the author mention a steamship？A.To indicate that it is warmer in the ocean than on land.
B.To show that a steamship is better than other kinds of ship.
C.To argue that man should use steamships more than other means of transportation.
D.To illustrate that man can make use of sources of energy from the sea.
It can be inferred from the passage that_______.A.man hasn’t completely developed the riches of the sea
B.technology for exploring the sea has been solved
C.planting rice in the sea will be made possible in a short time
D.in the near future man can live on the ocean floor
The word “exploit” in the last paragraph could best be replaced by________.A.evaluate

（）different is the college schedule from the one at high school schedule.

The Ebro Delta, in Spain, famous as a battleground during the Spanish Civil War, is now the setting for a different contest, one that is pitting rice farmers against two enemies: the rice-eating giant apple snail, and rising sea levels. What happens here will have a bearing on the future of European rice production and the overall health of southern European wetlands.
Located on the Mediterranean just two hours south of Barcelona, the Ebro Delta produces 120 million kilograms of rice a year, making it one of the continent’s most important rice-growing areas. As the sea creeps into these fresh-water marshes, however, rising salinity(盐分)is hampering rice production. At the same time, this sea-water also kills off the greedy giant apple snail, an introduced pest that feeds on young rice plants. The most promising strategy has become to harness one foe against the other.
The battle is currently being waged on land, in greenhouses at the University of Barcelona. Scientists working under the banner “Project Neurice” are seeking varieties of rice that can withstand the increasing salinity without losing the absorbency that makes European rice ideal for traditional Spanish and Italian dishes.
“The project has two sides,” says Xavier Serrat, Neurice project manager and researcher at the University of Barcelona. “the short-term fight against the snail, and a mid- to long-term fight against climate change. But the snail has given the project greater urgency.”
Originally from South America, the snails were accidentally introduced into the Ebro Delta by Global Aquatic Tecnologies, a company that raised the snails for fresh-water aquariums(水族馆), but failed to prevent their escape. For now, the giant apple snail’s presence in Europe is limited to the Ebro Delta. But the snail continues its march to new territory, says Serrat. “The question is not if it will reach other rice-growing areas of Europe, but when.”
Over the next year and a half investigators will test the various strains of salt-tolerant rice they’ve bred. In 2018, farmers will plant the varieties with the most promise in the Ebro Delta and Europe’s other two main rice-growing regions—along the Po in Italy, and France’s Rh？ne. A season in the field will help determine which, if any, of the varieties are ready for commercialization.
As an EU-funded effort, the search for salt-tolerant varieties of rice is taking place in all three countries. Each team is crossbreeding a local European short-grain rice with a long-grain Asian variety that carries the salt-resistant gene. The scientists are breeding successive generations to arrive at varieties that incorporate salt tolerance but retain about 97 percent of the European rice genome(基因组). Why does the author mention the Spanish Civil War at the beginning of the passage？
A.It had great impact on the life of Spanish rice farmers.
B.It is of great significance in the records of Spanish history.
C.Rice farmers in the Ebro Delta are waging a battle of similar importance.
D.Rice farmers in the Ebro Delta are experiencing as hard a time as in the war.
What may be the most effective strategy for rice farmers to employ in fighting their enemies？A.Striking the weaker enemy first
B.Killing two birds with one stone
C.Eliminating the enemy one by one
D.Using one evil to combat the other
What do we learn about “Project Neurice”？A.Its goals will have to be realized at a cost.
B.It aims to increase the yield of Spanish rice.
C.Its immediate priority is to bring the pest under control.
D.It tries to kill the snails with the help of climate change.
What does Neurice project manager say about the giant apple snail？A.It can survive only on southern European wetlands.
B.It will invade other rice-growing regions of Europe.
C.It multiplies at a speed beyond human imagination.
D.It was introduced into the rice fields on purpose.
What is the ultimate goal of the EU-funded program？A.Cultivating ideal salt-resistant rice varieties.
B.Increasing the absorbency of the Spanish rice.
C.Introducing Spanish rice to the rest of Europe.
D.Popularizing the rice crossbreeding technology.
