单选题 Disagreements among economists are legendary, but not on the issue of free trade. A recent survey of prominent economists both conservative and liberal concluded that an economist who argues for restricting international trade is almost as common today as a physician who favors leeching.
Why the consensus? International free trade, economists agree, makes possible higher standards of living all over the globe.
The case for free trade rests largely on this principle: as long as trade is voluntary, both partners benefit, otherwise they wouldn't trade. The buyer of a shirt, for example, values the shirt more than the money spent, while the seller values the money more. Both are better off because of the sale. Moreover, it doesn't matter whether the shirt salesman is from the United States or Hong Kong (or anywhere else).
The vast majority of American manufactures face international competition. This competition forces companies to improve quality and cut costs. By contrast, protectionism encourages monopoly, lower quality and higher prices.
Americans pay an enormous price for protectionism over $60 billion a year, or $1000 for a family of four. Thanks to protectionism, for example, American consumers pay twice the world price for sugar.
Free trade also makes the world economy more efficient, by allowing nations to capitalize on their strengths. The United States has an advantage in food production, for instance, while Saudi Arabia has an advantage in oil. The Saudis could undertake massive irrigation to become self-sufficient in food, but it is more economical for them to sell oil and purchase food from us. Similarly, we could become self-sufficient in petroleum by squeezing more out of oil shale. But it is much less costly to buy some of our oil from Saudi Arabia. Trade between our two countries improves the standard of living in both.
Protectionism is both wasteful and unjust. It taxes most heavily the people who can least afford it. Thus, tariffs that raise the price of shoes burden the poor more than the rich. Despite the powerful case for free trade, the United States and the rest of the world have always been protectionist to some degree. This is because free trade benefits the general public, while protectionism benefits special interest groups, which are better organized, better financed and more informed. To make matters worse, much of what we hear on this issue is misinformation spread by the special interests themselves.

单选题 The economists ______.
A. agree on the restriction of internal trade
B. disagree whether to restrict free trade or not
C. hold different arguments because of their different interests
D. agree on free trade
【正确答案】 D
【答案解析】[解析] 细节题。文章第一句指出“经济学家们有分歧是尽人皆知的,但在自由贸易问题上除外”,由此可知,D项“经济学家们在自由贸易问题上观点一致”为正确答案。A项“他们在限制国内贸易方面意见一致”,与本文主旨相反,因为限制贸易与自由贸易是对立的;B项“在是否限制自由贸易上观点不一”,与本文第一句意义相反;C项“因为他们的不同兴趣而各执己见”,与本文主题相悖。
单选题 What is the author's attitude toward protectionism denoted from the fifth paragraph?
A. Ironic B. Sincere
C. Gratefu. D. Appreciative
【正确答案】 A
【答案解析】[解析] 态度题。题干问作者对贸易保护主义的态度。根据第五段“美国人为贸易保护主义每年要耗费六百多亿美元高昂的代价,即四口之家每年要耗费1000美元。由于贸易保护主义,美国消费者购买糖不得不花费比世界市场高一倍的价格”。显然保护主义不但没有起到保护作用,反而得不偿失,而本文作者倡导的就是自由贸易,可知,作者对贸易保护主义持讽刺的态度,故A项正确。其他三项均表示“赞成的”意思,不可能全部都是答案。
单选题 According to the free trade principle, the author suggests that ______.
A. Saudi Arabia build its own food industry
B. Saudi Arabia import food from U. S.
C. U. S. become self-sufficient with its oil
D. U. S. explore its oil shale
【正确答案】 B
【答案解析】[解析] 细节题。题目意思是“根据自由贸易规则,作者提出什么建议”。根据第六段所列举的例子可知,美国在食品生产上占优势,而沙特阿拉伯在石油方面占优势。沙特能够通过大规模的灌溉实现食品方面自给,但通过卖石油购买食品更经济一些。同样,美国也可以通过从油页岩上挤出石油实现自给,但这样比从沙特直接购买石油耗资更大,由此可知B项“沙特应该从美国进口食品”为正确答案。其言外之意是“发展自己的食品业就不够经济”;同样道理,“美国自己在石油方面自给自足耗资巨大”,也就是说“使用油页岩开采石油”也是不值得提倡的。
单选题 Why has protectionism always been exercised even if it is wasteful and unjust? Because ______.
A. it helps to establish national industry of one's own
B. it can achieve an independent economy
C. it is favored by general public
D. it benefits some privileged few
【正确答案】 D
【答案解析】[解析] 细节题 。本题问“既然贸易保护主义又浪费又不公正,为什么还总是有贸易保护主义的存在”。根据文章最后一段倒数第二句可知,贸易保护主义使特殊群体受益。故选项D“它使有特权的少数人受益”为正确答案。其他选项与原文不符。
单选题 According to the passage, which of the following is NOT true?
A. International free trade may improve the standard of living all over the world
B. Economists are all in favor of the free trade policy
C. International free trade may create international competition
D. Protectionism has been abolished due to encouraging monopoly, lower quality and higher prices
【正确答案】 D
【答案解析】[解析] 细节判断题。本题要求判断哪一个不正确。根据文章第二段可知A项正确,“国际自由贸易可以促进全世界人们生活水平的提高”;根据第一段第一句可知B项正确,“经济学家们都赞同自由贸易政策”;根据第四段可知C项正确,“国际贸易促进国际竞争”;根据最后一段第四句“美国和世界上其他国家在某种程度上还经常采取贸易保护主义政策。”可知选项D(贸易保护主义已被废止)不正确。所以D项为正确答案。
