In fact, before the invention of chopsticks, Chinese ancestors actually used hands to eat, but how did they eat soup and porridge? 1. Chinese started to use chopsticks about 3,000 years ago in Shang Dynasty.

The records of using chopsticks have been found in many written books but lack physical evidence. 2. One says that Jiang Ziya, an ancient wise man, created chopsticks. There also go around some other stories. But there is no exact history record about the invention. We can only say that smart ancient Chinese invented chopsticks.

Using two slim sticks to pick up food is actually not difficult. You can do it if you practice it for some time, even if you are a foreigner. The key to managing chopsticks is keeping one chopstick in position while moving the other to pick up food. 3. Chopsticks are usually held in the right hand, and left-handed chopstick use is considered as improper in China. Playing with chopsticks is thought to be impolite. 4. Chinese philosopher Confucius advised people to use chopsticks instead of knives because the metal knives remind people of cold weapons, which mean killing and violence.

If you are truly interested in chopsticks, you can pay a visit to the Shanghai Chopsticks Museum. The museum gathered more than 1,200 pairs of chopsticks from China, Korea, Japan and Thailand. 5.

A. Chopsticks were introduced to many other neighbor countries due to its lightness and convenience.

C. Bamboo chopsticks are most frequently used in Chinese daily life.

An invention to tackle canal plastics pollution was one of the highlights of the recent Amsterdam International Water Week.

The instrument, named"the great Bubble barrier" is a bubble screen that will remove plastic trash from the canals and therefore prevent it from flowing through to the river IJ and the North Sea.

“This is a very important step in reducing the amount of plastic in the oceans,”co-inventor Philip Ehrhorn said “It is a lot easier to stop it at an earlier stage instead of in the ocean.”

The tool works as follows. By pumping air through a tube with holes in it, which is located on the bottom of a waterway, a bubble barrier appears. This creates an upward thrust, which brings waste to the surface of the water.

By placing it diagonally in the waterway, the barrier uses the natural current to guide the plastic to the catchment system at the riverside. Both ships and fish can pass through the Bubble Barrier, but plastic will be stopped.

The invention's origins go back around four years, when Dutch students Saskia Studer, Anne Marieke Eveleens and Francis Zoet looked at the bubbles of a beer glass in a bar and thought they should do something similar. Ehrhorn, a German student, had the same idea. After he found out about the plans of the three Dutch women, they decided to join forces in Amsterdam.

“It is the first step of many”, Ehrhorn continued on the project. “First, the different rivers and canals in the Netherlands-cities, industrial areas, ports. In the following years ,we will go to the rest of Europe, Asia and elsewhere.”

“We have learned to live with water and have built a thriving society.”Nijhof said.

1.What's a bubble barrier?

A.A dam made of concrete. B.An invention to trap plastic.

C.A canal to deal with waste. D.A container to hold beer.

2.According to Philip Ehrhorn, which of the following is true?

A.The barrier is effective in a way.

B.It's easy to deal with plastic.

C.This instrument can deal with all waste.

D.We can do nothing with sea waste.

3.Which paragraphs describe the barrier's working principle?

A.Paragraph 1&2. B.Paragraph 2&3.

C.Paragraph 3&4. D.Paragraph 4&5.

4.Which might be the best title of Paragraph 2&3 of the passage?

A.Plastic becomes easier to remove.

B.An action to remove the plastic.

C.An instrument will be invented.

D.A new invention to fight plastic pollution.

Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the way many North Americans interact (互动) these days. The term is “networked individualism”. This concept is not easy to understand because the words seem to have opposite meanings. How can we be individuals (个体) and be networked at the same time? You need other people for networks.

Here is what Professor Wellman means. Before the invention of the Internet and e-mail, our social networks included live interactions with relatives, neighbors, and friends. Some of the interaction was by phone, but it was still voice to voice, person to person, in real time.

A recent research study by the Pew Internet and American Life Project showed that for a lot of people, electronic interaction through the computer has replaced this person-to- person interaction. However, a lot of people interviewed for the Pew study say that’s a good thing. Why?

In the past, many people were worried that the Internet isolated (孤立) us and caused us to spend too much time in the imaginary world of the computer. But the Pew study discovered that the opposite is true. The Internet connects us with more real people than expected — helpful people who can give advice on careers, medical problems, raising children, and choosing a school or college. About 60 million Americans told Pew that the Internet plays an important role in helping them make major life decisions.

Thanks to the computer, we are able to be alone and together with other people — at the same time!

45. The underlined phrase “networked individualism” probably means that by using computers people ________.

A. stick to their own ways no matter what other people say

B. have the rights and freedom to do things of their own interest

C. do things in their own ways and express opinions different from other people

D. are able to keep to themselves but at the same time reach out to other people

46. According to the Pew study, what do many people rely on to make major life decisions?

A. Networks.      B. Friends.        C. Phones.        D. Parents.

47. It can be inferred from the Pew study that _______.

A. people have been separated from each other by using computers

B. the Internet makes people waste a lot of time and feel very lonely

C. the Internet has become a tool for a new kind of social communication

D. a lot of people regard the person-to-person communication as a good thing

48. Which would be the best title for this passage?

A. We’re Alone on the Internet.

B. We’re Communicating on the Internet.

C. We’re Alone Together on the Internet.

D. We’re in the Imaginary World of the Internet.

高二英语阅读理解中等难度题查看答案及解析

Instead of cruising in on a hoverboard, I rode my bike to the office today. The bicycle was invented in the 19th century. Instead of taking a pill for breakfast, I had a bacon roll, cooked using gas. Science fiction has ________ to us.

Making predictions is tricky, especially about the future, as physicist Niels Bohr joked. In science fiction, you can’t escape that ________ though. Since its birth in the 19th century, writers have ________ imagined the things to come: devices that humankind will invent to make life easier. But in so many instances, those promises have not come to pass. The biggest ________ are in travel—jet packs, hoverboards and flying cars are yet to fill the skies. Air travel has become significantly cheaper and wide-reaching, but only using distinctly 20th-century technology: commercial aeroplanes are much the same as they were 50 years ago.

________ is what science fiction frequently delivers, but its arrival in the real world has been unpredicrable. Domestic robots with a degree of intelligence are yet to ________, though robotic vacuum cleaners are commercially available—even if they are fairly hopeless. Video calls have now arrived—sort of—but conferencing on Skype is still dissatisfying. In mobiles, video call technology is now available, so when your dad rings to update you on his vegetable patch, he’ll be able to ________ your look of boredom.

The truth is that we quickly ________ the astonishment of invention: our wonderment is soon replaced with the feeling of nothing new. We should try to stay in that period of ________. It is astonishing that the contents of every book ever written can be stored in a small box. Or that you can carry 10,000 albums on an object kept in your pocket. Or that almost all the information in the world can be accessed almost anywhere at any time. All these ________ are dependent on the emergence of the microchip and its place in computers. Yet sci-fi didn’t ________ the dominance of the computer in running our lives.

But the real area where ________ far outstrips（超越）predictions is medicine. Sure, fiction would describe humans as“disease-free”but without going into detail.“Disease-free”humans are still absent, but the progress made in ________ life is breathtaking. With relative ease, we can sequence anyone’s genome（基因组），giving a read-out of our entire genetic code. This means we can find out the underlying genetic cause of thousands of diseases in minutes.

Photosensitive implants now exist that can replace damaged cells in the retina（视网膜）and can, thus ________ sight to the blind. While the inventions of science fiction can show great ideas we’d like to happen, nothing ________ the inventiveness of people in the real world.
