题目内容

Did you ever wonder who invented products like Liquid Paper, Kevlar or paper bags? Most would think a man invented these items. Guess what? Women invented each of these. What? You don’t believe me? Well, read this:
Liquid Paper was invented by Bette Nesmith Graham in 1951 and originally called Mistake Out. Being a typist, Bette was increasingly irritated with being unable to erase her typing mistakes. The messy business left her hands black and the paper dirty. Bette was good at painting and remembered that an artist paints over mistakes. She applied that same principle to typing mistakes and Liquid Paper was born, making Bette into a self-made millionaire.
Kevlar, yes, the Kevlar of the bullet proof vest（防弹衣）—what police officers and soldiers wear, was invented by Stephanie Kwolek. Stephanie worked for the DuPont Company as a research chemist. She was asked to find a high-performance fiber. Originally, this fiber was intended to be used for car tires (轮胎). However, the fiber she developed in 1964 was amazing and is still used in products such as sailboats, skis, shoes, and yes, bullet proof vests. In 1995 Stephanie was named to the National Inventor’s Hall of Fame.
Margaret Knight invented a machine that revolutionized the making of paper bags. Paper bags had been made like envelopes but Margaret developed a machine that would fold and paste（粘）a flat-bottom paper bag, the very same type we still use today. Margaret’s family was poor and she started working at the age of nine. Her first invention at the age of twelve was a safety tool for a loom（织布机）. Later she worked for the Columbia Paper Bag Company. It was there that she worked on improving the making of paper bags. She was issued her patent（专利）in 1870.
So next time you use a new product or an old one, will you wonder who made it? Do some research on the web and answer a few questions like: Who invented it? How was it invented? You may be surprised at some of the stories you uncover.

We can achieve knowledge either actively or passively（被动地）. We achieve it actively by direct experience, by testing and proving an idea, or by reasoning.

We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. Although we are used to passive learning, it’s not surprising that we depend on it in our everyday communication with friends and co-workers.

Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is rumor (谣言).

Did you ever play the game Rumor? It begins when one person writes down a message but doesn’t show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn, whispers it to still another, and so on. Then the last person writes down the message word for word as he or she hears it. Then the two written statements are compared. Typically, the original message has changed.

That’s what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own feelings to a story, trying to improve it, marking it with their own personal style. Yet those who hear it think they know.

This process is also found among scholars and authors: A statement of opinion by one writer may be re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts.

According to the passage, passive learning may occur when a person is _______.

A. doing a medical experiment B. solving a math problem

C. watching news on TV D. doing scientific reasoning

The underlined word “it” in Paragraph 2 refers to _____.

A. active learning B. knowledge C. communication D. passive learning

The author mentions the game Rumor to show that _____.

A. a message may be changed when being passed on

B. a message should be delivered in different ways

C. people may have problems with their sense of hearing

D. people tend not to believe in what they know as rumor

What can we infer from the passage?

A. Active learning is less important.

B. Passive learning may not be dependable.

C. Active learning occurs more frequently.

D. Passive learning is not found among scholars.

Did you ever look up at the moon and think you saw a man’s face there? When the moon is round and full, the shadows(影子) of the moon mountains and the lines of the moon valleys sometimes seem to show a giant nose and mouth and eyes. At least, some people think so.
　　If there were a man on the moon—instead of mountains and valleys that just look like the face of a man—what would he be like?
　　He would not be like anyone you know. He would not be like anyone anybody knows.
　　If the man on the moon were bothered by too much heat or cold the way Earth people are, he could not stay on the moon.
　　The moon becomes very, very hot. It becomes as hot as boiling water. And the moon becomes very, very cold. It becomes colder than ice.
　　Whatever part of the moon the sun shines on is hot and bright. The rest of the moon is cold and dark.
　　If the man on the moon had to breathe to stay alive, he couldn’t live on the moon because there’s no air there. He’d have to carry an oxygen tank, as astronauts do. There’s no food on the moon, either. Nothing grows—not even weeds（grass）.
　　If the man on the moon liked to climb mountains, he would be very happy. There are many high places there, such as the raised land around the holes, or craters(火山口), of the moon. Some of these rims are as tall as Earth’s highest mountains.
　　But if the man on the moon liked to swim, he would be unhappy. There is no water on the moon—just dust and rock.
　　When you think of what it’s like on the moon, you may wonder why it interests our scientists. One reason is that the moon is Earth’s nearest neighbor—it is the easiest place in space to get to.
　　Going back and forth between the moon and Earth, astronauts will get a lot of practice in space travel. Things learned on moon trips will be of great help to astronauts who later take long, long trips to some of the planets.
　　Scientists are also interested in the moon because it has no air. The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes. A telescope on the moon would give them a clearer, closer view of the stars.（words: 411）
【小题1】What is the reason why our scientists are interested in the moon.?

A．The moon is beautiful.

B．The moon is different from the earth.

C．The moon is Earth’s nearest neighbor—it is the easiest place in space to get to.

D．The moon is the easiest place in space to get to and it has no air, unlike Earth.

【小题2】The underlined word “rim” in the Paragraph 8 means _________ .

【小题3】What is the main thought of the passage?

A．We can learn much from research on the Moon.

B．There may be human beings on the moon.

C．If there were a man on the Moon, there would be many similarities between the man on the Moon and on the Earth.

D．A telescope on the Moon would help scientists have a clearer, closer sight of the stars.

Although English is not as old as Chinese , it is spoken by many people around the world every day. English speakers are always creating new words and we are often able to know where most words come from.
Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They didn’t speak good English, but they ate good food. When some Americans saw them eating round piece of beef, they asked the Germans what it was. The Germans didn’t understand the question and answered, “We come from Hamburg.” One of these Americans owned a restaurant, and had an idea. He cooked some round piece of bread and started selling them. Such bread came to be called “hamburgers”. Today, “hamburgers” are sold in many countries around the world.
Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting, too. This reason, for most English words, can be found in any large English dictionary.

Why Exercise Is Cool?

1. Exercise Strengthens Muscles

Did you ever do a push-up or swing across the monkey bars at the playground? 1. By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.

2. 2.

Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion,” which means you can move your arms and legs freely without feeling tightness or pain.

3. Exercise Keeps the Balance

3. Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff. 4. If you’re not very active, your body won’t need as many calories.

Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.

4. Exercise Makes You Feel Good

It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping, and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.

But you may not know that exercising can actually put you in a better mood. 5. It’s just another reason why exercise is cool!

A. So you want to do some aerobic (有氧的) exercise right now?

B. Food gives your body fuel in the form of calories, which are a kind of energy.

C. When you exercise, your brain releases a chemical, which may make you feel happier.

D. Those are exercises that can build strength.

E. Exercise Makes You Flexible

F. Exercise Makes Your Heart Happy

G. But if you’re active, your body needs an extra measure of calories or energy.
