根据短文理解，完成下列各题。

Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel. One group held a special event to display（展示）new kinds of cars .The new cars are different and they can run on many different kinds of fuels.

Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels. One kind of them runs on a special fuel cell which is filled with a gas called hydrogen.

The fuel cell cars are also better in another way. They give off no emissions（排放物）. They are very clean, and don't give off bad fumes when they are running.

One man who makes fuel cell cars is excited about the hydrogen fuel cell technology. He says we will never run out of the sources of the fuel, but we may run out of the oil. Once we use oil up, it will take millions of years for more oil to form. Since gasoline is made from oil, that could be a problem for companies that make traditional cars, and for drives. However, it won't be a problem for cars that run on fuel cells.

Buses that run on hydrogen fuel cell power are being tested on the road. They could become a common form of transportation in the near future

（1）、From the first paragraph we know that _______.

A、cars are more expensive now B、people are poorer now than before C、drivers have to pay more to fill their cars with gasoline D、it's useless to have a car

（2）、What does the underlined word “hydrogen” mean?

A、氢 B、磷 C、钾 D、钙

（3）、Which of the following is not the advantage of the hydrogen fuel cell car?

A、It's better to the environment to drive it. B、We will never use up the source of the fuel. C、It can avoid road accidents. D、It doesn't give off bad fumes when it runs.

（4）、What's the problem for traditional cars?

A、Oil will be used up. B、Traditional cars will be forbidden to drive. C、It's hard to learn to drive. D、Fuel cell cars have more advantages.

（5）、What's the main idea of the passage?

A plant makes its own food in its leaves . Water comes to the leaves through the roots . Air gets into the leaves through very small holes . The green coloring in the leaves uses the water and air to make the food for the plant . It also needs sunshine because a plant can make food only when the sun is shining.
Animals and people could not live without green plants . They both eat plants . People and some animals also eat the meat of some animals and these animals eat plant

      Roosegaarde, an artist and designer from Dutch has thought of a device(装置). He hopes it will make Beijing's sky clear again and help the people with masks breathe fresh air again in Beijing.
     An electromagnetic field(电磁场) will pull the dirty particles in the air to the ground, and then they can be easily cleaned.
Roosegaarde says, "It's like when you have a balloon which has static electricity(静电) and your hair goes toward it. Smog happens the same way as the hair."
      His workplace has reached an agreement with the Beijing government to test the technology in one of the capital's parks. Beijing's skies are regularly covered by grey smog. Serious cases of air pollution are often reported in Beijing. Roosegaarde says an indoor test has already shown it works well and he is confident of the results. With the help of a team of scientists and engineers, he is sure that the device can be worked outside.
     "Beijing is a very good place to test the device because the smog in Beijing is quite low and there's not so much wind." says Roosegaarde. "We'll be able to make the air pure but the most difficult thing is to remove the smog. As a result, you can see the sun again."
     Roosegaarde also reminds us that his aim is not only to give a plan to solve Beijing's dirty air pollution but also to make people pay attention to the environment problem. He adds, "This is not the real answer for smog. The real answer to do with it is clean cars, different industry and different lifestyles. " However, he hopes the project will make the citizens realize the differences between clean air and smog-filled air.

Today people can use the phone to talk with others almost anywhere on the earth. But when you use the phone, you don't see the person you are talking with. That may change in the near future.

Today some people are using a kind of telephone called the picture phone or vision phone. With it, two people who are talking can see each other.

Picture phones can be useful when you have something to show the person you're calling.

They may have other uses in the future. One day you may be able to ring up a library and ask to see a book. Then you'll be able to read the book right over your picture phone. Or you may be able to go shopping through your picture phone. If you see something in the newspaper that you think you want to buy, you'll go to your phone and call the shop. People at the shop will show you the thing you're interested in right over the phone. You'll be able to shop all over the town and never leave your room!

Brooke wanted a dollhouse and some sugar cookies. So the 6-year-old asked Alexa to get them. Alexa wasn't her mom or babysitter. It was a voice-activated home assistant powered by AI (人工智能). And it made Brooke's wishes come true. A few days later, much to her parents' surprise, a $170 dollhouse and four pounds of cookies showed up. They ate the cookies and gave away the dollhouse to a local hospital. And that's not the end of the story. When a news reporter told the story of what happened on TV, Alexa devices (设备) in many listeners' homes woke up and tried to order dollhouses!

Alexa isn't the only AI willing to serve you. Apple Home Pod has Siri, Google Home has its Assistant, and the upcoming Galaxy Home device will have Bixby. People who have these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report from The Information, nowadays voice shopping is rare. But many scientists predict a boom (增长) in voice shopping in the near future. Is that a good thing?

▲ You can shout out an order as soon as you think of it, even if you are cooking, cleaning, or driving. In addition, people with disabilities who are unable to use a keyboard or mouse can shop without any help.

But voice shopping has its disadvantages. Unwanted dollhouses aren't the biggest problem. It's usually very easy to cancel an order or return products. The thing that worries some people is that these assistants are always listening. They have to be able to respond when you want them. So they listen for "Alexa" or "OK Google" or another order. When they hear it, they start recording the conversation. Some have worried about what happens shopping habits? And what if someone hacks (入侵) the device? The CIA found a way to hack smart TVs to turn them into spies that listen all the time. Others could do the same with any smart device.

What do you think? Are you ready to start voice shopping?

It's important to learn things about protecting environment. Here's a 4Rs rule for us.

Reduce

If you want to reduce waste, you should use things wisely (明智的). A large number of trees are being cut down to make paper. If everyone uses paper carelessly and then throws it away, soon we would not have any trees left. Some other things are also being wasted, and people don't know what to do with waste in big cities, so it's necessary to reduce waste.

Reuse

You should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you don't use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.

·Recycle

Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money, for example, cola cans are sent to a factory, where they're smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.

Repair

If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it's better for you to sell the old ones or give them to other people who can use them after doing some repair.

Choose the best answers.

Bamboo(竹子) is one of nature s most surprising plants. Many people call this plant a tree, but it is a kind of grass.

Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 metres in 24 hours! There are more than 1, 000 kinds of bamboo. Bamboo grows almost everywhere in the world, but in Europe, they can't grow.

Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimetres wide while others may grow to be more than 30 centimetres across. This plant also comes in different colours, from yellow to black to green.

Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.

Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting(支撑) new buildings and bridges while they are being built.

In Africa, poor farmers are taught how to bring water using bamboo. These African countries need cheap ways to bring water because they have no money, and their crops often die from no rain and no water. Bamboo pipes(管子) help poor farmers bring water to their thirsty fields without spending much money.
