Many schools are 【26】______ parental impatience and are purchasing hardware without 【27】______ educational planning, so they can say, OK, we've moved into the computer age.

Much unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction. Computers are often used as part of automated(自动化的) production systems requiring a least possible number of operators, causing the loss of many jobs. This has happened, for example, in many steelworks.
On the other hand, computers do create jobs. They are more skilled and better paid, though fewer in number than those they replace. Many activities could not continue in their present form. without computers, no matter how many people are employed. Examples are the check clearing (交换) system of major banks and the weather forecasting system.
When a form. introduces computers, a few people are usually employed in key posts (such as jobs of operations managers) while other staff are w-trained as operators, programmers, and data preparation staff. After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees. This decrease is sometimes balanced by a substantial increase in the activity of the frim, resulting from the introduction of computers.
The attitudes of workers towards computers vary. There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult.
On the other hand, many workers regard the trend toward wider use of computers inevitable.They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs. This view was supported by the former British Prime Minister, James Callaghan in 1954, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long ran.
The unfriendly feeling towards computers is developed from 查看材料
A.the possible widespread unemployment caused by their introduction
B.their use as part of automated production systems
C.the least possible number of operators
D.the production system in steelworks

West lake College in Virginia will start a laptop computer program that allows students to do school work anywhere they want. Within five years,each of the 1,500 students at the college will receive a laptop. The laptops are a part of a $10 million computer program at West lake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak”with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students.
State Officials also are testing laptop programs at other universities,too.
At West lake College, more than 60 percent of the staff use the computers. The laptops will allow all teachers to use computers in their lessons. As one West lake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”
1.The main purpose of the laptop program is to give each student a laptop to ____.
A、access the Internet
B、work at home
C、use for their schoolwork
D、connect them to libraries
2. Why is the word “speak” in the second paragraph in quotation mark？____
A、They don’t really talk
B、They use the computer language
C、Laptops have speakers
D、None of the above reasons is correct
3. Which of the following is true about West lake College？____
A、It is an old college in America
B、All teachers use computers
C、1,500 students have laptops
D、Students there can do everything
4.A window on the world in the last paragraph means that students can____.
A、attend lectures on information technology
B、travel around the world
C、get information from around the world
D、have free laptops
5.What can we infer(推断) from this passage？____
A、The program is successful
B、The program is not workable
C、The program is too expensive
D、We don’t know the result yet

Q: Which type of credit card is not mentioned in the conversation？
(19)
A．Smart Card.

Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform. some sight and hearing functions, which could make life easier for the blind and deaf. They're also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who's lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom.
Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work -- they'll just turn on a terminal
A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform. tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days.
These modern and potential computer uses are possible because of the silicon microchip.
These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor.
As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer.
Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!
What is the purpose of the passage？
A．To tell the readers what computers will look like in the future.
B．To show the close relations between man and computers.
C．To tell the readers how important silicon microchips are.
D．To talk about the possible future uses of computers.
W: But I' ve been trying to find a new job in another company. You see, I' ve worked here for 3 years without a raise. That' s unfair to me.
