仁爱科普版九年级下Unit 6 Topic 1 I would rather watch TV plays than sports shows.同步练习

根据短文内容,选择正确答案。

      Have you seen Avatar(《阿凡达》)? It's a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images(图像)from the movie look as if they were coming straight towards you. 

More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies are more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

      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. 3D technology uses two film projectors(投影机). One 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. So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy(头晕的) or have headaches. A famous eye doctor said if your eyes can't focus(聚焦) on the same object at once, you will have trouble watching 3D movies.

(1)、According to the passage, Avatar is a ______.

A、digital camera B、digital TV set C、3D movie D、4D movie
(2)、The 3D glasses can make the images from the movie ______.

A、look more beautiful than usual B、look as if they were coming straight towards you C、look as if they were far away from you D、look more clear than usual
(3)、People will have ______ in their homes in the near future.

A、3D computers B、3D phones C、3D movies D、3D TV sets
(4)、When we look at an object, ______.

A、each eye sees the object at the same angle B、our brain puts the two different pictures together C、there will be two film projectors in our eyes D、our brain can't put together the images sent to our eyes
(5)、If you wear a pair of 3D glasses, ______.

A、you will see different images in both eyes B、your brain can't work at all C、the images can be put together easily by your brain D、our brain can put the images together

    Sheridan is a town in Indiana, USA. There are lots of trees near the public schools in the town. Their leaves turn sunlight into energy(能量).

    In Sheridan, the sun not just provides energy for plants. It keeps schools running, too. The schools use solar panels(太阳能电池板) to turn sunlight into energy.

    The science behind solar energy is not new. But Sheridan Community Schools is the first school district(学区) in Indiana to be completely solar-powered. The district finished putting in solar panels for all three of its schools in 2016. Some of the panels can turn to follow the sun across the sky.

    In 2008, fewer than 1. 000 schools used solar power. By 2014, there were 3, 727 schools with solar panels in the USA. These numbers come from a report by the Solar Foundation. Roxie Brown, a program director there said that the number of schools with solar panels has continued to go up since 2014.

    Solar energy has some advantages over other energy sources(来源). Sunlight is a renewable source, which means it won't run out. Solar panels don't harm the environment. Also, sunlight is free. So by using solar power, schools can save money on energy costs.

    Brown thinks more schools should run on solar energy. "The sun is Earth s energy source," she says. "We're trying to make it the energy source for our houses cars and schools, too."

    But using solar energy isn't always easy. Solar panels can be expensive to put in. The panels also take up space. But for many schools, going solar is worth it.

How can you remember a song for a long time? Why does your teacher use songs to teach you English? There is a scientific reason for this. 

Researchers (研究者) are studying the relationship between music and remembering a foreign language. "Singing could be a new way of learning, especially for a foreign language. The brain likes to remember things in a catchy (悦耳易记的) and relaxing way. For example, children can remember difficult words quickly when they are in a song," said Dr. Karen Ludke. If children find it difficult to learn foreign languages, this new way may help. On his blog (博客), Dr. Ludke wrote "A listen—and—repeat singing way can help to learn foreign languages and open the door for future research in this area."

Many language teachers know the importance of music and they often use it in teaching and learning. Hua Zhuying, a teacher at a Chinese language school in Washington DC, likes using songs in teaching Chinese. She said, "I use music all the time to teach children Chinese. For little kids usually we use English songs but teach them the Chinese lyrics. Not only does it work, but it is fun for children. Sometimes I think if I learned English that way when I was young, maybe I could speak English much better."

Our brain likes music in learning languages, especially for remembering. If you are still having problems in learning a language, why not try singing it out?
