16During the summer you should be even more careful than usual of the foods you prepare. Foods spoil faster in hot weather than in cold weather. When you are shopping, purchase frozen and refrigerated foods, don’t make long stops on your way home because frozen foods could become soft or warm. Using insulated (密封的) bags helps keep food cold until you arrive home. Mild or milk products should be refrigerated immediately. When camping or picnicking or at any time when refrigeration isn’t available, use special dry foods. Above all , if a food doesn’t seem to be normal in odor(氣味) or appearance, discard (拋棄) it immediately. Don’t taste it.
What is the main idea of the passage?
A How to store frozen and refrigerated foods
B How to keep food from spoiling (變壞) during the summer?
C How to select fresh food?
D How to prepare summer food
17A new era(紀(jì)元) is upon us. Call it what you will: the service economy, the information age, the knowledge society. It all translates to be a basic change in the way we work. Already we are there now. The percentage of people who earn their living by making things has fallen fortunately in the Western World. Today the major of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number in on the rise. More women are in the workforce than ever before. There are more part-time jobs. More people are self-employed. But the wildness of the economic change can’t be measured by numbers alone, because it also is giving rise to a radical(根本的、徹底的) new way of thinking about the nature of work itself. Long-held views about jobs and careers, the skills to succeed, even the relation between individuals and employers—all these are being challenged.
We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possible could have foreseen the ways in which a single invention, the chip(芯片), would change our world thanks to its use in personal computers, digital biotechnology(數(shù)碼生物技術(shù)), artificial (人工的) intelligence or even some still unimagined technology could produce a similar wave of unexpected changes. But one thing is certain: information and knowledge will become even more important ,and the people who have it , whether they work in manufacturing (制造業(yè)) or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by using information instead of performing regular work will be valued above all else. If you look forward 10 years, information services will be predominant(占優(yōu)勢(shì)). It will be the way you do your job.
Which of the following can be the vest title of the passage?
a. Computer and Knowledge Society.
b. Service Industry in the Modern Society
c. Characteristics of the new Era
d. Fast Development of Information Technology
18It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The difference between schooling and education implied by this remark is important.
Education is much more open-ended and all-inclusive than schooling. Education knows not limits. It can take place anywhere, whether in the school or on the job, whether in a kitchen or on a tractor. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agent (doer) of education can vary from respected grandparents to the people arguing about politics on the radio, from a child to a famous scientist. Whereas schooling has a certain predictability（可預(yù)料性）, education quite often produces surprises. A chance conversation with a strange may lead a person to discover how little is know of other religious (宗教) . People receive education from infancy(嬰幼兒) on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, and one that should be a necessary of one’s entire life.
Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive school at about the same time, take the assigned seats, are taught by the adult, use similar textbooks, do homework, take exams, and so on. The pieces of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have been limited by the subjects being taught. For example, high school students know that they are likely to find out in their classes the truth about political problems in their society or what the newest filmmakers are experimenting with. There are clear undoubtful conditions surrounding the formalized of schooling.
What is the main idea of this passage?
A The best schools teach a variety of subjects.
BEducation and schooling are quite different experiences.
A. The more years students go to schools, the better their education.
B. Students benefit from schools, which require bong hours and homework.
19Since the beginning of time, man has invented many interesting things. Some of these inventions, like numbers, the alphabet and the radio, have certainly changed history. Since 1946, one of the most important inventions has been the computer. It will change all our lives.
At one time it was as large as a room, and quite difficult and slow to operate. But, since the invention of the silicon ship, which is really a very very small electric circuit, computers have been greatly improved. They have become smaller, easier to use, and faster; they can store a lot more information.
Some computer are made as well as television sets. Simple computers can be made smaller than a book. And computers are getting smaller all the time.
There are several reasons why the computer is useful to us. Firstly, it can store a very very large quantity of information in its memory. Secondly, the computer can operate very quickly –thousands of times faster than a human—and it will not tire. Thirdly, modern computers can be built into other kinds of machines, like radios, cars, planes and so on. They can do many kinds of work.
Soon, almost everyone, either at home or at work, will use some kind of computer. the lives of all of us will be changed by this invention.
The main idea of this passage is ____
A how the computer came into being
B that computers ate getting smaller and smaller all the time
C that the computer will change the lives of all of us
D that modern computers can be built into other machine
20 The computer is an electronic machine. It is a machine that solves problems as much as you do. As an example, let’s trace the way you would add two numbers. Then, let’s see how a computer would do it.
Step1. You collect information. That is, you either see or hear the numbers to be added.
Step2. You find a method to solve the problem. In this case, you remember how to do addition.
Step 3 You bring together the information (the two numbers), and the method (addition)
Step 4 You perform the operation, adding the two numbers.
Step5 You report the results of your work, either by writing down the answer or by saying it aloud.
All computers go through five similar steps.
Step 1 The computer receives information, or data, from the outside. It changes the data into electric language, called input.
Step 2 The computer has been given a program contain instructions for solving the problem. The instructions ate found in the storage or memory.
Step 3 The computer bring together the data from the input and the instructions from the storage. This is done by the computer’s control.
Step 4 The computer goes through the steps of the instructions on the data; this is called processing.
Step 5 The computer changes the result from electric language to human language. It presents the results in print or sound, called output.
Sometimes the five parts of a computer –input, storage, control, processor , and output—are together in one large unit. Other times they are far apart and connected by wires. Often, large computers have one control and processing unit, with a number of separate memory, input, and output device.
What does the passage mainly tell us?
A The computer is an electric machine.
B Computer solve problems in the same way as people do
C How we add two numbers
D Computers have five parts together in one unit.
What is the main idea of the passage?
A How to store frozen and refrigerated foods
B How to keep food from spoiling (變壞) during the summer?
C How to select fresh food?
