Science is a dominant theme in our culture. Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist.
This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or – independently of any course – simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture.
We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.
We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living.
According to the passage, ‘scientific subculture’ means
[A] cultural groups that are formed by scientists.
people whose knowledge of science is very limited.
[C] the scientific community.
[D] people who make good contribution to science.
We need to know something about the structure and operation of science because
[A] it is not easy to understand the things that excite and frustrate scientists.
Science affects almost every aspect of our life.
[C] Scientists live in a specific subculture.
[D] It is easier to understand general characteristics of science.
The book mentioned in this passage is written for readers who
[A] are intelligent college students and lay person who do not know much about science.
are good at producing various gadgets.
[C] work in a storehouse of dried facts.
[D] want to have a superficial understanding of science.
According to this passage,
[A] English is a sexist language.
only in the scientific world is the role of women increasing rapidly.
[C] women are making significant contributions to eliminating the inadequacy of our language.
[D] male nouns or pronouns should not be used to refer to scientists.
This passage most probably is
[A] a book review.
the preface of a book.
[C] the postscript of a book.
[D] the concluding part of a book.

More than 20 million kids in the United States live with one parent. Separation and divorce are the most common reasons for this. In other cases, the mom and dad may never have lived together, or one of them may have died.
Living with one parent instead of two can bring about a lot of emotions. These feelings can be pretty strong, and they can be confusing, too. You might feel terribly sad and angry because your parents divorced.
Single parents are often working parents because someone needs to earn money to buy food, clothing, and a place to live in. Having a job means your mom or dad is able to provide these things and more for you. People work for other reasons, too. A job can let a person use his or her special talents and skills. A job can be important because it helps people in the community.
But even though you might understand why your mom or dad has to work, sometimes it can be hard to accept. This can be especially true during the summer or school vacations. You’re home, they’re gone, and the days can seem really long.
It can be tough when you don’t have enough time with your dad or mom. When you live with one parent, that person really has to do the work of two people. Besides a job, your mom or dad is responsible for caring for the kids, the house, the yard, the car and the pets. So what can you do ?
One of the best ways is to hold a family meeting. Talk about everyone’s schedule for work, school, and activities. You can also talk about what jobs around the house need to be done every day. You might want to help your parent cook dinner sometimes. That can be both fun and helpful to your parent. Maybe you can also schedule a weekly game or a movie at night.
What are the main reasons for kids’ living with one parent?

A.Separation and divorce. B.A lot of emotions.
C.Working and caring for the kids. D.Working parents.

Which of the following statements is NOT true according to the passage?

A.Some kids live with one parent for the other’s death.
B.Living with one parent can cause a lot of emotions.
C.Working means a mom or dad is able to provide things for their kids.
D.Kids can also talk about what jobs in their school can be done at a family meeting.

It can be inferred from the underlined sentence (in Paragraph 4 ) that ______

A.the kid in the company of friends does want help
B.the kid who plays with both parents does need their love
C.the kid lacks both parents’ love does feel lonely
D.the kid who understands parents’ work does be helpful

On a hot African morning, Leila was lying on her stomach and an elephant was walking towards her. Leila waited. Then she pushed the button on her camera. “And I got my best photo of an elephant ever, by lying under my car,” Leila explained. “I wanted to get close to the elephants, but of course this was dangerous; they had their babies with them. So every morning I used to park my car in the open near the path (小道). They used to take the same path every morning when they left the water hole. After a week, they were used to seeing my car. So the next morning, I lay under it and got my photo!”
Many of the best wildlife photos come from good planning. In Africa, photographers set up their hides (隐匿处) near water holes. They also set up hides near forest paths, as animals use the same paths every night. For bird-watching, many lakes have hides. Inside the hides, bird-watchers can watch all day in the shade (荫处) out of the wind and rain.
Good wildlife photos are needed for books, postcards, magazines and newspapers. But a success rate of 1 in 20 is good.
Why did Leila lie under her car on the stomach?

A.Because she wanted to sleep.
B.Because she wanted to take photos but was afraid of the animals.
C.Because it’s easy to see the elephants.
D.Because it’s very comfortable.

How can photograpers take good photos?

A.By making good preparation. B.By going into the forest at night.
C.By walking around the holes. D.By going to the nearest lake.

Which of the following statements is right according to the passage?

A.All animals go to water holes at night.
B.Lakes are good places for bird-watching.
C.Leila used her car to prevent the sunshine.
D.Animaals pay no attention to photographers.

What can we know from the underlined sentence?

A.The successf rate of taking wildlife photos is 50% at most.
B.Photographers who take wildlife photos need more practice.
C.To take good wildlife photos is not difficult.
D.It’s hard to take good wildlife photos.

Have you ever noticed someone "talking" to them-selves? What did you think? The word "crazy" probably came to your mind. Wait a minute, though. Maybe they’re doing something meaningful.
Speaking practice can be effective in many different forms when people learn English or another foreign language. Imitating the speech of others is proven to be highly effective in developing a native speaker’s level of fluency in a language. Actually you’ve already proven that to your-self.
How? That’s how you learned your first language! Whether it was English, Spanish, French or some other language, you "imitated" your mother, father, other family members, friends, teachers and whoever else was around making "talking" noises at you as you formed your first communicative language skills.
So don’t think those who are talking to themselves are "crazy". At least don’t do so until you’ve tried it for your-self, in English or in your new foreign language.
As you go through your day, in English or your new foreign language, tell yourself what you’re doing at the moment and what you’re going to do during the day.
"Which of these shirts, ties, etc. should I wear today? Not this one, I wore it just last week. Maybe this one, but I don’t like this color with the pants. Let’s try another one," you might say as you are getting dressed.
If you live alone, you can talk aloud whenever you want without disturbing others. If you don’t live alone, however, then first explain to your family or roommates what you’ll be doing, to avoid a quiet phone call to the local psychiatrist (精神病学家).
The author wrote the passage mainly to _______.

A.tell us how to talk to ourselves
B.introduce a method of learning a foreign language
C.tell us why some people talk to themselves
D.explain to us how we learned our native language

What does the underlined word "it" in the fifth paragraph refer to?

A.The word "crazy". B.A foreign language.
C.The skill of communicating. D.The method of talking to oneself.

From the passage we can know that ______.

A.people who talk to themselves are crazy
B.if you live alone, you should talk to yourself
C.you should tell yourself what you’re doing
D.we learned our native language by imitating

An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity (创造力), an old idea can suddenly become something new.
However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas(集思广益), designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified.
Anyone can be an inventor —even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention —earmuffs (保暖耳罩)!
The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design.
Many other famous inventors started young as well. Margaret Knight —the inventor of the flat-bottomed brown paper bag —is said to have created a safety device for textile looms(织布机) when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions!
In most cases, an invention ________ according to the first paragraph.

A.comes from a complete new idea B.is usually based on an old product or idea
C.will change its creator’s life completely D.is created by scientists in different fields

The second paragraph mainly wants to tell us _______.

A.the difficulty in making a new invention B.the common steps of creating new things
C.having a good idea is the key to creation D.designing a tool is the first step in inventing

The example of Chester Greenwood is used to show that ________.

A.children can also invent something
B.it is easy even for children to make inventions
C.kids have more advantages in inventing things
D.to be an inventor is the best way to change one’s life

At first Chester designed his earmuffs in order to ________.

A.protect his ears while ice-skating
B.earn money to support his poor family
C.realize his dream of becoming an inventor
D.make himself look fashionable while ice-skating

Students who say they never or hardly ever used dictionaries may speak English well but usually write poorly, because they make many mistakes.
The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.
The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check this in a dictionary.
The writer thinks that ___________.

A.choose a good dictionary, and you’ll be successful in learning English
B.dictionaries are not necessary to the students who learn English
C.it is very important for students to use good dictionaries properly
D.using dictionaries very often can’t help to improve writing

According to the passage, which of the following is WRONG?

A.Dictionaries have little effect on learning to speak English.
B.Whatever new words you meet while reading, never use dictionaries.
C.Small two-language dictionaries have serious shortcomings.
D.Reading something for the first time, you’d better not use dictionaries.

When in the reading does the writer advise students to use a good dictionary?

A.At the beginning of the reading B.At the end of the reading
C.During the first reading D.After the first reading

This passage mainly tells us .

A.that students shouldn’t use small two-language dictionaries
B.what were the shortcomings of small two-language dictionaries
C.why students should use large college edition dictionaries
D.what dictionary students should choose and how to use it
