听力原文： How many men do housework？ Recently a European commission tried to find out people's ideas and reactions to the women's movement. As part of the survey, they asked many men and women the question, "Who does the housework？" The men answered very differently from the women!

The housework they asked people about was: preparing meals, washing dishes, cleaning the house and baby-sitting. 48% of British husbands said they did these things. 37% of Danish men helped in the house. But only 15% of Italian men said they did the housework; many of them said they never helped at all.

But there was an interesting point of view from the wives. According to British wives, only 38% of their husbands helped in the house. And Italian wives said that their husbands hardly ever helped. The Italian and British men did not tell the truth! The commission found that Danish men were the most trustful husbands; their answers were the same as their wives' answers.

听力原文： As is known to all, scientists and philosophers had studied the human body and its functions from very early times. Unfortunately, many of the ideas and theories, correct and incorrect, were accepted without question for a great number of years. But by the 16th century, knowledge gained through chemical experiments was beginning to make some people think more deeply about how the human body works.

A most important medical discovery was made by William Harvey in 1628. He found out that the blood is circulated round the body in one direction only by the pumping action of the heart. It had previously been incorrectly thought that the blood moved with a backward and forward motion.

Early in the 17th century a new instrument came into use that was to open up a whole new area in the study of medical and scientific matters. This was the microscope.

The first instruments were not very efficient. They were able to magnify only a very small part of the object and this was always surrounded by rings of colored light. Nevertheless a great step forward had been taken which was of vital importance for future research and development.

A．Scientists and philosophers had never studied the human body and its functions.

B．Many of the ideas and theories that people used to accept were all incorrect.

C．People used to accept ideas and theories.

D．People used to accept undoubtedly many of the ideas and theories, correct and incorrect.

If spelling becomes the only focal point of his teacher's interest, clearly a bright child will be likely to"play safe". He will tend to write only words within his spelling range, choosing to avoid adventurous language. That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.

I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible ! There are far too many spelling errors and your writing is illegible." It may have been a sharp criticism of the pupil's technical abilities in writing, but it was also a sad reflection on the teacher who had omitted to read the essay, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the errors, but if his priorities had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek improvement.

Teachers differ in their opinions about ______.

A．the difficulties in teaching spelling

B．the role of spelling in general language development

C．the complexities of the basic writing skills

D．the necessity of teaching spelling

What makes a person a scientist？ (是什么使一个人成为科学家？) Does he have ways or tools of learning that are different from those of others？ The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works. The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations. nextItem What makes a scientist according to the passage？ ________ A.The tools he uses.

B.The way he uses his tools.

C.His ways of learning.

D.The various tools he uses.

What is the main idea of the passage？ ________A.The theory of relativity.

B.Exactness is the core of science.

C.Scientists are different from ordinary people

D.Exactness and ways of using tools are the keys to the making of a scientist

The underlined part in the passage shows_______.A.the importance of information

B.the importance of thinking

C.the difference between scientists and ordinary people

D.the difference between carpenters and people with other jobs

A sound scientific theory should be one that _________.A.works not only under one set of conditions at one time, but also under the same conditions at other times

B.does not allow any changes even under different conditions

C.can be used for many purposes

D.leaves no room for improvement

The author quotes the case of Albert Einstein to illustrate __________.A.that measurements are keys to success in science

B.that accuracy of mathematics

C.that investigations are important in science

请帮忙给出每个问题的正确答案和分析，谢谢！

Questions （1）to（5） are based on the following passage:

What makes a person a scientist？ Does he have ways ---or tools ---of learning that are different from those of others？ The answer is no. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power saw is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works

The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the condition permit. What works under one set of conditions at one time mustwork under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was latter tested through investigation. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurement. Then the measurements are used to make mathematical calculations that may test his investigations.

Many, many centuries ago, large distances were measured in the Babylonian mile. The Babylonian mile equaled about seven of our miles. Because of its length, the time needed to travel the Babylonian mile became a measure of time. One day was said to be twelve Baby-Ionian time-miles.

About one thousand years before Christ, the Babylonians began keeping records of star movements. They needed a way to record how much time passed between the moment they first saw a star and then observed it again. They used the Babylonian time-mile as their measure of time.

In order to have small units of time, the Babylonians divided their time-mile into thirty parts. The Babylonians believed that each trip around the sky was a circle. One complete trip around the sky, they reasoned, took one day.

You already know that one day was the same as twelve Babylonian time-mile. Since each time-mile was divided into thirty parts, the circular trip around the sky was 12×30, or 360 parts long. That is how there came to be 360 4egrees in a circle.

The purpose of this passage is to explain ______.

A．how the Babylonians measured the time of star movements

B．why the circle is divided into 360 degrees

C．the Babylonian mile and the Babylonian time-mile

D．the Babylonians' ideas about the sky

听力原文： The purpose of communication is to get your message across to others. This is a process that involves both the sender of the message and the receiver. This process leaves room for errors, with messages often misinterpreted by one or more of the parties involved. In fact, a message is successful only when both the sender and the receiver perceive it in the same way. By successfully getting your message across, you convey your thoughts and ideas effectively.

In a recent survey of recruiters from companies with more than 50,000 employees, communication skills were cited as the single most important decisive factor in choosing managers. The survey points out those communication skills, including written and oral presentations, as well as an ability to work with others, are the main factors contributing to job success.

In spite of the increasing importance placed on communication skills, many individuals continue to struggle with this, unable to communicate their thoughts and ideas effectively. This inability makes it nearly impossible for them to compete effectively in the workplace.

Getting your message across is paramount to progressing. To do this, you must understand what your message is, what audience you are sending it to, and how it will be perceived. You must also weigh in the circumstances surrounding your communications.

A．How to communicate effectively.

B．Why successful communication are important.

C．What communication is.

D．How to avoid direct communication.

听力原文： Almost all states in America have a state fair. They last for one, two or three weeks. The Indiana state fair is one of the largest and oldest state fairs in the United States. It is held every summer. It started in 1852. Its goals were to educate, share ideas, and present Indiana's best products. The cost of a single ticket to enter the fair was 20 cents.

During the early 1930's, officials of the fair ruled that the people could attend by paying with something other than money. For example, farmers brought a bag of grain in exchange for a ticket. With the passage of time, the fair has grown and changed a lot, but it is still one of Indiana's most celebrated events. People from all over Indiana and from many other states attend the fair. They can do many things at the fair.

They can watch the judging of the price cows, pigs, and other animals, they can see sheep getting their wool cut, and they can learn how that wool is made into clothing; they can watch cows giving birth. In fact, people can learn about the animals they would never see except at the fair. The fair provides a chance for the farming communities to show its skills and farm products. For example, visitors might see the world's largest apple, or the tallest sunflower plant.

Today, children and adults at the fair can play new computer games, or attend more traditional games of skill. They can watch performances put on by famous entertainers. Experts say such fairs are important, because people need to remember that they're connected to the earth and its products, and they depend on animals for many things.

(30)

A．For people to share ideas and show farm products.

B．For officials to educate the farming community.

C．For farmers to exchange their daily necessities.

D．For farmers to celebrate their harvests.
