Exposure to loud noises can definitely produce a partial or complete loss of hearing, depending on the intensity, duration, and frequency composition of the noise. Many jobs present noise hazards (危险), such as working in factories and around jet aircraft, driving farm tractors, and working in music halls where rock bands are playing. In general, continuous exposure to sounds of over 80 decibels can be considered dangerous. Decibel values correspond to various sounds. Sounds above 85 decibels may, if exposure is for a sufficient period of time, produce significant hearing loss. Noise can have unexpected harmful effects on performance of certain kinds of tasks, for instance, if one is performing a watch keeping task that requires vigilance (注意), in which he is responsible for detecting weak signals of some kind (e. g. , watching a radar screen for the appearance of aircraft).
Communicating with other people is unfavorably affected by noise. If you have ridden in the rear of a jet transport, you have noticed that it was difficult to carry on a conversation at first, and that, eventually you adjusted the loudness of your speech to compensate for the effect. The problem is noise.
Noise differs from sound in that ______.
A.noise interferes with the task being done
B.noise is a special type of loud sound
C.noise is usually unavoidable in big cities
D.noise can be defined more precisely than sound

In this country, there is far more to apprehend from Congress, than from the executive, as is seen in the following reasons: —Congress is composed of many, while the executive is one, bodies of men notoriously acting with less personal responsibilities than individuals; congress has power to enact laws, which it becomes the duty of the executive to see enforced, and the rally legislative authority of a country is always its greatest authority; from the decisions and constructions of the executive, the citizen can always appeal to the courts for protection, but no appeal can lie from the acts of congress, except on the grounds of unconstitutionality, the executive has direct personal responsibilities under the laws of the land, for any abuses of his authority, but the member of congress unless guilty of open corruption, is almost beyond personal liabilities.
It follows that the legislature of this country, by the intention of the constitution, wields the highest authority under the least responsibility, and that it is the power most to be distrusted. Still, all who possess trusts, are to be diligently watched, for there is no protection against abuses without responsibility, nor any real responsibility, without vigilance.
Political partisans, who are too apt to mistake the impulses of their own hostilities and friendships for truths, have laid down many false principles on the subject of the duties of the executive. When a law is passed, it goes to the executive for execution, through the executive agents, and, at need to the courts for interpretation. It would seem that there is no discretion vested in the executive concerning the constitutionality of a law. If he distrusts the constitutionality of any law, he can set forth his objections by resorting to the veto; but it is clearly the intention of the system that the whole legislative power, in the last resort, shall abide in congress, while it is necessary to the regular action of the government, that none of its agents, but those who are especially appointed for that purpose, shall pretend to interpret the constitution, in practice. The citizen is differently situated. If he conceives himself oppressed by an unconstitutional law, it is his inalienable privilege to raise the question before the courts, where a final interpretation can be had. By this interpretation the executive and all his agents are equally bound to abide. This obligation arises from the necessity of things, as well as from the nature of the institutions. There must be somewhere a power to decide on the constitutionality of laws, and this power is vested in the supreme court of the United States, on final appeal.
The author's purpose in writing this passage is to indicate ______.
A.the difference between kings and presidents
B.the power of the Supreme Court
C.the limitations of the presidency
D.the irresponsibility of Congress

That industry (whose roots, outside America, are usually attributed to tinkerings by Messrs Daimler and Benz in Germany) is being celebrated hugely over the coming months, culminating with a Great American Crnise-in in Detroit in June. "Our goal is to attract the greatest collection of antique and classic cars this nation has ever seen in one place at one time," says Mr Skramstad modestly.
Americans may indeed blame the car for almost everything that has happened to their country, and themselves, since 1896. The car has determined.
The way they live. From cradle to grave, the car marks every rite of American passage. Home by car from the maternity ward; first driving licence (usually at the age of 16); first (backseat) sexual experience; first car of one's own (and the make of car is a prime determinant of social status, symbolic of everything a person is or does). In Las Vegas, and elsewhere, Americans can get married at drive-in chapels. They then buy, or lust after, a house with garages big enough for not one but two or three cars. This allocates more space to cars than to children. And when the time comes, they may lie in state at a drive-through funeral home, where you can pay your respects without pulling over.
The way they shop. Main Street has been replaced by the strip mall and the shopping mall, concentrating consumer goods in an auto-friendly space. A large part of each shopping trip must now be spent, bags under chin, searching for the place where the car was left. (And another point: bags have annoyingly lost their carrying handles since shoppers ceased to be pedestrian) Since car-friendly living and shopping became the role, most built-up parts of America now look like every other part. There is simply no difference between a Burger Inn in California and one on the outskirts of Boston.
The way they eat. A significant proportion of Americans' weekly meals are now consumed inside cars, sometimes while parked outside the (drive-by) eatery concerned, sometimes en route, which leads to painful spillages in laps, leading to overburdening of. The legal system. Dozens of laws have been written to deal with car cases, ranging from traffic disputes to product liability. Drive-by shootings require a car, as do most getaways. The car is a great crime accessory; and it also causes the deaths of nearly 40,000 Americans every year.
Personal finances. Before the age of the car, few people went into debt; no need to borrow money to buy a horse. Now Americans tie themselves up with extended installment loans, and this in turn has spawned a whole financial industry.
The wealth of the nation. By 1908, an estimated 485 different manufacturers were building cars in the United States. Employment grew nearly 100-fold in the industry during the first decade of the 20th century. When Henry Ford, in a stroke of genius, automated his production line he required a rush of new, unskilled labour, which he enticed by offering an unheard-of $5 a day in wages. Henceforth, workers could actually afford to buy what they built.
And Americans never looked back. Today, the Big Three car manufacturers (Food, GM and Chrysler) generate more than $200 billion a year in business inside the United States. Directly and indirectly, the industry employs roughly one in seven workers. Every car job is reckoned to add $100,000 in goods and services to the economy, twice the national a
A.introduce new models of automobiles
B.emphasize automobiles have brought wealth to the nation
C.commemorate the centenary anniversary of the birth of the American motor industry
D.illustrate the rapid development of automobile industry in America
