Bicycles are used by people of all ages aroun...

Bicycles are used by people of all ages around the world. It's common in many cities to see thousands of bikes streaming down a street.

At first, only men rode bicycles. It was thought that only men could run machines, and that women wouldn't be able to control a bicycle. In the 1890s, though, with women's growing independence(独立), bicycles offered women a way to travel by themselves. Today, of course, men, women, and children ride bicycles.

Most bikes today have two wheels, but you've probably seen other kinds, too.

Some people start riding bikes that have three wheels. The third wheel makes the bike easier to balance. These bikes are called tricycles. As you've seen, the bi- in bicycle means "two". The tri- in tricycle means "three". Bikes with three wheels aren't just for young children. They matter to adults because bikes with three wheels can help move people or things. The most common kind of adult tricycle is the rickshaw(黄包车). Rickshaws are used as bike taxis in many parts of the world.

Some bikes also have only one wheel and no handlebars(把手). These bikes are called unicycles. The first part of the word, uni-, means "one". Riding a bike with only one wheel is a balancing act—that's why unicycles are used in the circus(马戏团).

There are also bikes with four wheels. Bikes with four wheels are called quadracycles. Again, the first part of the word refers to the number of wheels. In this case, quadra-means "four".

根据上面短文内容填空。

1.People of all ages ________ bicycles around the world. It's common in many cities to see ________ bikes streaming down a street.

Skills vs. Knowledge in Education

Education systems all over the world are based on the idea that students get and remember information from teachers and books. These systems test this knowledge with standardized tests which compare students to each other. They only test the kind of information which is possible to measure(测试，测量) in tests. The goal is gaining information, not developing skills by which to use and make information. Unlike the old style of education where people remembered things in order to pass tests and get higher scores than other students, the modern world calls for a new kind of education in which the focus(焦点) is deep understanding, creativity and information management skills.

Einstein said "Imagination is more important than knowledge. Knowledge is limited. Use information in creative ways. Knowledge is what other people have created. Understanding is all about what you think about something. Everybody sees, hears, feels and thinks differently. No two people in the world have the same understanding of the same thing. It is impossible to give tests on a point of view. Because of this, tests are illogical. The only reason tests exist is to label(归类) students as "smart" or "stupid". There are many kinds of intelligence(智力，智能), however. One of the most famous researchers in the field of intelligence, Gardner, found at least seven different kinds of intelligence. Intelligence and understanding are related. Unfortunately, tests only measure one kind of intelligence.

In the modern world skills are more important than knowledge. If a person knows many facts, it is impressive, but not very useful. It is of much greater importance to be able to find information quickly, organize that information, analyze(分析) and understand the main ideas, put different pieces of information together, and create new information. Together these skills make what we call information management and innovation, the skills which are most desired(期望) in the business world.

Most people in the world believe that education is about remembering things to take tests which measure one's performance against other people who have studied the same information.

However, this idea no longer matches the reality of the modern world in which knowledge is less important than creativity and deep understanding. To be successful in the age of technology, education must focus on helping students gain information management and innovation skills.

1.The new kind of education in the modern world doesn't focus on ________.

A.creativity B.gaining information

C.deep understanding D.information management skills

2.According to the passage, which of the following is useless?

A.You do as what your teacher tells you in class.

B.You examine a text first carefully to understand what it means.

C.You organize your ideas so that people can understand and follow you.

D.You come up with a solution by asking the questions and understanding the problem.

3.What's the passage mainly about?

A.How people can live in the age of technology.

B.What knowledge tests measure in the age of technology.

C.How students develop themselves in the age of technology.

D.What education helps the students to gain in the age of technology.

Then in 1743, the French king had a “flying chair”. His men lifted the king up to the second floor by using ropes. Although elevators had been improving over time, people were afraid to use them. People liked the idea of an elevator, but they believed it might suddenly fall.

In 1853, Elisha Otis invented the modem elevator. He made safety brakes(刹车) to stop the elevator from falling. Otis had been thinking about peoples fear of elevators.

The world uses about a thousand million tons of water a day. Water is a human right(权利)and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.

Treating wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.

While 75% of our planet is covered with water, only 2% is fresh water — that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19, 000 factories have been built around the world, mostly in coastal countries. They process(加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.

Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

1.Treating wastewater helps the environment by __________.

A.storing waste in ice and snow B.waste in ice and snow

C.keeping waste out of rivers and oceans D.sending waste to coastal countries

Everyone faces difficulties in their life. Daniel Kish was born with a special eye illness and lost his eyesight before he was only 14 months old.

Soon after, however, he started to do an amazing thing. He learned to make clicks with his tongue to help him move around. Kish now moves about using sonar. He is so good at it that he can ride a bicycle by himself on public roads. And he started the organization World Access for the Blind(WAFTB) in 2000, teaching others how to use sonar. In the interview with National Geogra phic, ,he explains how the sonar works.

“When I make a click sound, it produces sound waves. These waves reflect off surfaces all around and return to my ears. My brain then deals with the sound and turns it into pictures in my mind. Each click is like a camera flash, which helps me make a 3­D picture of my surroundings for hundreds of feet. It's like having a conversation with the environment.”

Kish feels it is exciting to ride a bike using sonar, although he needs to click twice a second, much more than he usually does. “It may sound a bit dangerous to move around the world in this way,” he says. “But most people in the world live in fear of things that they imagine. I love hiking and mountain­biking. I go almost everywhere. And I've never had an accident and hurt myself.”

He is happy to be able to help more blind children to improve their life.“We've served over 10，000 students in nearly 40 countries,” he tells the reporter. “Many students are surprised how quickly results come. Seeing isn't in the eyes. It's in the mind.”

Today, the world’s diversity(多样性) of food crops is quickly decreasing. But scientists around the world are taking action. They are building seed banks. At seed banks, scientists store the seeds of many different crops.

There are now 1,400 seed banks around the world. However, some banks are in warm countries. If the electricity fails, the seeds will get too hot and die. Other seed banks are in countries troubled by war. Sometimes people damage the seed banks. If this happens, valuable seeds can be lost forever!

The organization Global Crop Diversity Trust decided they wanted to deal with this problem. So, they decided to build a global seed bank. This seed bank would contain a back-up, or extra copy, of all the world’s seeds. Smaller seed banks would still collect and keep local seeds. But they would also send copies of their seeds to the global bank.

Scientists from the Global Crop Diversity Trust chose the cold, snowy mountains of Svalbard, Norway to build the global seed bank — the Svalbard Global Seed Vault. Organizations, farmers, or local seed banks store their extra seeds there. And the people who place their seeds in the vault are the only people who can take them out. They pay to ship their seeds to Norway, but it does not cost them any money to store their seeds. The Global Crop Diversity Trust pays for this.

Cary Fowler is a scientist who heads the Global Crop Diversity Trust. He said, “If the Seed Vault simply supplies seed banks with copies of seeds that those banks lost by accident, the Seed Vault will be worth way more than it cost.”

1.Seed banks are built to ________.

A.research on seeds B.produce new seeds

C.protect crop diversity D.increase the number of seeds

2.What is the author's purpose in Paragraph 2?

A.Scientists store the seeds of many different crops at seed banks.

B.If seed banks are destroyed, valuable seeds will be lost forever.

C.Scientists want to build a global seed bank.

D.The people who place their seeds in the vault are the only people who can take them out.

3.Compared with other seed banks, the global seed bank ________.

A.was built by the government B.is more welcomed by farmers

C.is mainly used by great scientists D.can provide a good environment for seeds

4.What can we learn about the Svalbard Global Seed Vault?

A.It helps to pay the shipping cost. B.No one can take seeds out of there.

C.There are no fees to store seeds there. D.It mainly receives seeds from farmers.
