city, efficiency and versatility that they have practically "invaded" almost each and every human domain(领域). They have undoubtedly gone far beyond the expectations of a generation that had already lived under the spell(一段时间) of the TV set.
Throughout history there have been inventions that have been particularly remarkable and influential(有影响力的) within the scope of transport, education, health or communication. They have brought out comfort, health, knowledge or power. Some of them have produced minor effects; others have brought about very great changes. Think of the invention of the wheel, the automobile or the printing press, and what about the computer？
At the beginning the computer was thought mainly as an instrument to be used in the mathematical field, but soon people from other sciences began to get interested in this little "brain" that was capable of performing thousands of operations in a few seconds without getting tired or confused. They realized it could not only store millions of pages of information but also organize it in every possible way enabling man to carry out tasks unthinkable by other means.
Computers are now everywhere. They can make vehicles at supersonic(超音速的) speed and precision; they can control world banking transactions(交易), predict weather conditions, conduct an aircraft or a space craft, play instruments, manage nuclear weapons; they can operate on human patients, they can transfer information from one continent to another in seconds, they can...they can...they can... Yet, thank God, they still need human beings: to draw the instructions, to design the programs or to push the button!
Which of the following is true according to the passage？
A．All inventions have brought about complete changes.
B．Few of the inventions have brought about minor changes.
C．The inventions of the wheel and the automobile are not remarkable and influential.
D．We've benefited from the comfort, health, knowledge or power brought out by the inventions.
As far as ______ is concerned, computers have made a rapid growth in the last decade.
A．versatility
B．capacity

It is difficult to imagine what life would be like without memory. (78)The meanings of thou- sands of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.
Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involving any change in the way an animal typically behaves. (79)Memory is involved when a rat gives up eating grain be- cause he has sniffed something suspicious in the grain pile. Memory is also involved when a six- year-old child learns to swing a baseball bat.
Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 " words" —ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for ex- ample, the number of faces and places that the teenager can recognize on sight.
The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person' s memory is in terms of words and combinations of words.
According to the passage, memory is considered to be ______.
A．the basis for decision making and problem solving
B．an ability to store experiences for future use
C．an intelligence typically possessed by human beings
D．the data mainly consisting of words and combinations of words
Most companies expect IT (Information Technology) managers to head an IT staff of computer technicians. But IT managers can also specialize in other areas. Some managers may also be responsible for keeping their company’s Internet safety. They protect both their company and their online customers from thieves.
Other managers focus more on the business rather than the technical part of computing. They become project managers, helping companies reach as many online customers as possible.
Some companies also look for IT managers who can act as trainers. These trainers help a company’s computer technicians keep up-to-date on computer skills.
Most companies require their IT managers to have both a bachelor’s degree and some experience in the computer field. Often, companies hire IT managers out of their existing staff of computer technicians.
Since IT managers are extremely important to companies’ success, it’s no surprise that they receive such high salaries – around US $56,000 a year to start with. And, in such a fast-changing field,
managers’ salaries usually increase after only a couple of years.
The world will be watching to see just how quickly e-commerce replaces the old ways of doing business. And as computers change the way the world does business, IT managers will be in the middle of it all. Few companies can survive without them.
Besides being the leader of computer technicians, IT managers are also expected to be ________.
(A) experienced product designers
(B) skilled online technicians
(C) doctorate holders
(D) online safety specialists

[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.

Even without taking the technology to its limits, the idea of education as a lifelong process is catching on throughout the industrialized world. Already, working adults who pursue their studies part-time make up roughly half of students taking college courses in the United States.
However, there is debate in scholar circles about how far new technology should be used for teaching academic subjects in which personal contacts between teacher and student are still vital. Britain's Open University, for example, a world leader in distance education, has embraced information technology cautiously, believing it to be no substitute for books and the exchange of ideas at live tutorials and summer schools.
But the Open University is also moving with the tide. It has set up a "knowledge media institute" to explore ways of adopting information technology. Some teachers are concerned about this trend, arguing that the heavy investment that students are expected to make in computer and communications equipment contradicts the concept of "open" cost, of course, is and important factor in many developing countries, where few people have computers or even phones. Rather than uniting the world, the new technologies could lead to societies of information haves and have-nots.
Distance learning is different from the traditional correspondence course in that______.
A．it requires the individual student to work alone
B．it enables all the students to work at the same pace
C．it allows students to discuss with one another and their teachers
D．it enables geographically scattered students to study in the same physical classroom
