[Quotas , tariffs and subsidies</div>]
Like most wars,a trade war may bring about desired economic or political changes, but in the long run almost everyone suffers ,including those whom the trade war was meant to help.
An efficient carmaker, for example, may ask for limits of foreign imports, hoping to keep its price high without improving the quality of its products. In the end , however , other countries may retaliate with trade restrictions of their own. Consumers and businesses in both countries are then forced to buy poorly made and expensive domestic products. Trade restrictions might protect a few jobs in inefficient industries,but the whole economy often suffers by becoming less competitive in the international markets.
The most common tools for limiting imports of foreign goods and services are quotas, tariffs,and subsidies. When a country imposes a quota, it limits the quantity of certain foreign products that can be imported. A tariff is a tax placed on goods entering a country , raising the price of imported goods. A government can also use the taxpayers' money to provide a subsidy to local producers , making the price of local goods artificially lower than imported goods.
Trade barriers, like walls between feuding neighbors, are usually imposed unilaterally by one country acting on its own to limit the amount of foreign products available to local producer from foreign competition and allow them time to improve their products or lower their prices as long as they are protected from foreign competition by trade barriers.
Although trade restrictions are of dubious economic value, they have been shown to be effective in bringing about political or social change. The refusal of countries to trade and do business with South Africa, for example, was widely seen to be responsible for the decision to dismantle the system of apartheid. Trade blockades can be useful in forcing countries to change policies that violate human rights or international treaties, but as long as a sufficient number of countries join in the blockade to make it effective.

The doctors expressed concern that patients were eating too much and were generally overweight. The doctors said this was particularly worrying as they were seeing more and more young people with weight problems. But it was not just their patients eating too much concerned doctors, but the quality of the food as well.
The doctors said that many of their patients led busy lives and did not have time to cook traditional meals. Because of this many of them were turning to unhealthy fast foods. Sales
of this type of food have been increasing steadily over the last decade, although there were signs that the rate of growth is declining. The doctors felt that there was a clear link between over- consuming of fast food and health problems among their patients.
But the report was not all bad news. The doctors interviewed also reported an increased awareness of the importance of healthy eating among their patients. Many reported an increase
in the number of patients they see who had switched to a healthy organic diet.

Questions 31 to 35 are based on the following passage:
Designing a lens can be compared to playing chess. In chess a player tries to trap his opponent's king in a series of moves. In creating a lens a lens designer attempts to “trap” light by forcing all the rays arising from a single point in the subject to focus on a single point in the image, as a consequence of their passing through a series of transparent(透明的) elements with precisely curved surfaces. Since in both cases the ultimate goal and the means by which it can be attained are known, one is tempted to think there will be a single best decision at any point along the way. The number of possible consequences flowing from any one decision is so large, however, as to bevirtually, if not actually, infinite. Therefore in lens design, as inchess, perfect solutions to a problem are beyond reach. Although this article will be concerned only with the design of photographic lenses, the same principles apply to all lenses.
The lens designer has one enormous advantage over the chess player: the designer is free to call on any available source of help to guide him through the staggering number of possibilities. Most of that help once came from mathematics and physics, but recently computer technology, information theory,chemistry, industrial engineering and psychophysics have all contributed to making the lens designer's job immeasurably more productive. Some of the lenses on the market today were inconceivable a decade ago. Others whose design is as much as a century old can now be mass produced at low cost. With the development of automatic production methods, lenses are made by the millions, both out of glass and out of plastics. Today's lenses are better than the best lenses used by the great photographers of the past.Moreover, their price may lower, in spite of the fact that 19th century craftsmen worked for only a few dollars a week and today's lenses are more complex. The lens designer cannot fail to be grateful for the science and technology that have made his work easier and his creations more widely available, but he is also humbled: it is no longer practical for a fine photographic lens to be designed from beginning to end by a single human mind.
31.Lens design and chess playing are similar in that ____.
A) the final goal and the means by which it can be reached are known
B) perfect solutions to a problem can be found
C) any one decision at any point along the way to the goal can bring numerous possible results
D) both A and C
32.The final goal of designing a lens is ____.
A) to trap the opponent's lenses
B) to focus light with lenses
C) to hand make lenses at low cost
D) to reflect light by means of curved surfaces
33.After the passage the author will talk about ____.
A) the principles of designing lenses
B) techniques of making contact lenses
C) the design of photographic lenses
D) styles of lenses
34.Which of the following words cannot be used to describe today's lenses?
A) More delicate. B) Cheaper. C) Numerous. D) Unpopular.
35.Lens designers today ____.
A) have a large source of help to fall back on B) receive a low salary
C) are less respectable than those of the past D) are not decisive in the lens design
