Many United States companies have, unfortunately, made the search for legal protection from import competition into a major line of work. Since 1980 the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidies by foreign governments. Another 340 charge that foreign companies “dumped” their products in the United States at “less than fair value.” Even when no unfair practices are alleged, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief.
1. The passage is chiefly concerned with
(A) arguing against the increased internationalization of United States corporations
(B) warning that the application of laws affecting trade frequently has unintended consequences正确
(C) demonstrating that foreign-based firms receive more subsidies from their governments than United States firms receive from the United States government
(D) advocating the use of trade restrictions for “dumped” products but not for other imports
(E) recommending a uniform method for handling claims of unfair trade practices
In terrestrial environments, gravity places special demands on the cardiovascular systems of animals. Gravitational pressure can cause blood to pool in the lower regions of the body, making it difficult to circulate blood to critical organs such as the brain. Terrestrial snakes, in particular, exhibit adaptations that aid in circulating blood against the force of gravity.
1.In the passage, the author is primarily concerned with doing which of the following?
A Explaining adaptations that enable the terrestrial snake to cope with the effects of gravitational pressure on its circulatory system正确
B Comparing the circulatory system of the sea snake with that of the terrestrial snake
C Explaining why the circulatory system of the terrestrial snake is different from that of the sea snake
D Pointing out features of the terrestrial snake’s cardiovascular system that make it superior to that of the sea snake
E Explaining how the sea snake is able to neutralize the effects of gravitational pressure on its circulatory system
According to a recent theory, Archean-age gold-quartz vein systems were formed more than two billion years ago from magmatic fluids that originated from molten granite-like bodies deep beneath the surface of the Earth. This theory is contrary to the widely held view that the systems were deposited from metamorphic fluids, that is, from fluids that formed during the dehydration of wet sedimentary rocks.
The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth's surface and were found because they had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still lead to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression.更多相关内容请点击》GMAT阅读篇章结构之现象解释。
