The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid-we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard(蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we'd need huge feet that we could bring up to our ears in order to create adequate "hitting."

But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a tot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子) in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.

Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink and take a shower afterward!

（1）、Walking on water hasn't become a reality mainly because humans .

A、are not interested in it B、have biological limitations C、have not invented proper tools D、are afraid to make an attempt

（2）、What do we know about Basilicus basilicus from the passage?

A、It is light enough to walk on water. B、Its huge feet enable it to stay above water. C、It can run across water at a certain speed. D、Its unique skin keeps it from getting wet in water.

（3）、What is the function of the cornflour according to the passage?

A、To create a thick liquid. B、To turn the water into solid. C、To help the liquid behave normally. D、To enable the water to move rapidly.

（4）、What is the author's attitude toward the idea of humans' walking on water?

A、It is risky but beneficial. B、It is interesting and worth trying. C、It is crazy and cannot become a reality. D、It is impractical though theoretically possible.

    There are few families in the United States that do not have either a radio or television set. Both of them have become a necessary part of our daily life, keeping us filled with the news of the day, teaching us in many fields of interest, and making us happy with singing, dancing and acting.
    Marconl, the Italian inventor, who gave us the radio, probably didn't know how much his great invention would have done for the world in the years to come. Radio had, perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happen. Travelers in or out of–the–way places, ships at sea even astronauts round the earth are able to keep in touch with each other by radio.
    Television is another important invention. It lets us see as well as hear the actor. Since its appearance, TV has done a great deal in the daily life of people everywhere. Many programs are now televised in color.
    Perhaps the most modern invention is “Telstar”, a “star” moving round the earth. It makes it possible for the people all over the world to be closer than ever before. Now a family in Chicago can watch on TV a motor–car race in Italy, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!

Have you seen Avatar？It's a popular movie this year. It is three-dimensional(3D), so you may have to wear a special pair of glasses to see it. The 3D glasses make the images(图像) from the movie look like they are coming straight at you.
More and more 3D movies are coming to theaters. 3D TV sets have been produced in Japan now. Three-dimensional technology can make TV and movies more exciting. But people with eye problems may get headaches if they spend too much time watching 3D movies.
When we look at an object(物体), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大脑), and the brain puts them together. That's how we see depth(深度). So when we watch a 3D movie, one film projector(投影机) projects a left eye image and the other projects a right eye image. 3D glasses allow us to see a different image in each eye.
There are a lot of people walking around with very less serious eye problems. Under normal situations, the brain can adjust to their eyes so they can see things normally.
But when they are watching a 3D movie, the images projected to their eyes can't be put together by their brain. So the brain needs to work harder at reading the images. That makes it easier for these people to get headaches.
Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot see in 3D at all.

A hundred years ago, most people thought that human beings would never fly. And the idea of flying seemed crazy and dangerous. But as a new world full of new inventions（发明物）came, everyone was trying to break the old thoughts. So many inventors, like Orville and Wilbur Wright, tried to make a flying thing.

Most plane inventors at that time were impulsive. They would think of an idea, make a plane as quickly as they could, and then try to fly it as soon as possible. All of them had the same result they took their planes home and they had no idea why they didn't work.

However, the Wright brothers were much smarter inventors. They tested their ideas in smaller or safer ones before making a real plane. For example, the Wright brothers made a wind tunnel(隧道)to compare(比较)wing shape ideas. They also flew lots of kites to test their ideas. They studied the way birds fly through the air and tried to learn something from it when making their models. Finally, the Wright brothers felt they were ready to test their planes, but they needed to find the right place. They knew the right place to test their planes after writing to the US Weather Bureau for help. At last on December 17th, 1903, Orville and Wilbur tested the plane and they made it.

The plane flied for twelve seconds and it traveled just 120 feet, but Orville and Wilbur were very happy. Their plane really worked! By the end of the day, both brothers had great successful flights(飞行), with Wilbur having a record of 852 feet in 59 seconds.

New sea bridge opens in China

A new bridge just opened on October24.The long bridge links(连接)three cities. It is the HongKong-Zhuhai-Macao Bridge(HZMB).The bridge looks like the letter "Y ".It is 55 kilometers long. It is the world's longest sea bridge. China spent nine years building this bridge. The HZMB is not just a bridge, but also part tunnel(登道）and part island .In one part, the bridge turns into an undersea tunnel. The tunnel passes through two man-made islands. Large ships can pass by above the tunnel. The HZMB makes it much faster to travel between the three cities. It takes 45 minutes to go from Hong Kong to Zhuhai. In the past, it took four hours.

Chinese scientists made headlines last year by cloning（克隆）a pair of monkeys-Zhong Zhong and Hua Hua. Their names come from the Chinese words zhonghua, or "Chinese nation ". The monkeys were cloned using the same techniques(技术）that were used to produce Dolly, the world's first cloned animal, about 20 years ago. The monkeys could be used as a model to study genetic(遗传的）diseases, including some cancers(癌症）.

As one saying goes, where there are Chinese people, there are kungfu legends. Jin Yong was regarded as one of the greatest kung fu fiction writers in China. And for many people, he built a magical kungfu kingdom that they could escape into every now and then. But this kingdom is falling apart now, because he passed away on October 30, 2018, at the age of 94.

How green are you? Do you know how to be green?

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

Reduce

Reduce means "use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

Reuse

Reuse means "use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup of a paper bag. It's better to use a china cup and a lunch box because you can use them again.

Recycle

Recycle means "change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

So please remember these three words: reduce, reuse and recycle.
