Magnesium is another mineral we now obtain by collecting huge volumes of ocean water and t
reating it with chemicals. Although originally it was derived only from brines or from the treatment of such magnesium-containing rocks as dolomite, of which whole mountain ranges are composed. In a cubic mile of sea water there are about four million tons of magnesium. Since the direct extraction method was developed about 1941, production has increased enormously. It was magnesium from sea that made possible the wartime growth of the aviation industry, for every, air plane made in the United States (and in most other countries as well) contains about haft a ton of magnesium metal. And it has innumerable uses in other industries where a lightweight metal is desired, besides its long-standing utility as an insulating material, and its use in printing inks, medicines, and toothpaste.

What is the main topic of this passage?

A.Use of sea water.

B.Treatment of sea water.

C.Chemical properties of magnesium.

D.Derivation and users of magnesium.

The number of speakers of English in Shakespeare's time is estimated to have been about fi
ve million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language, as well as various levels of usage that are employed both in its spoken and written forms.

It is virtually impossible to estimate the number of people in the world who have acquired an adequate working knowledge of English in addition to their own language. The purposes for which English is learned and the situations in which such learning takes place are so varied that it is difficult to define and still more difficult to assess what constitutes an adequate working knowledge for each situation.

The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the infinite needs of its native speakers, English is a language in which some of the most important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the dissemination(传播)of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce industry, law and education as well as for international communication and for access to the scientific and technological development in the West.

There are about 260 million people who can speak ______.

A.English in its regional variety

B.English in its standard variety

C.English as a second language

D.English as a working language

第9题
A pilot cannot fly a plane by sight alone. In many conditions, such as flying at night and
landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300, 000 kilometers in one second. A radar set sends out a short burst of radio waves: Then it receives the echoes produced when the waves bounce off objects. By determining the time it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word "radar," in fact, gets its name from the term "radio detection and ranging." "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots, radar is essential for air traffic control, tracking ships at sea, and for tracking weather systems and storms.

What is the main topic of this passage?

A.The nature of radar.

B.Types of ranging.

C.Alternatives to radars.

D.History of radar.
