What's going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 0 years from now, according to the BBC.

 Digital money      

      We used to pay with cash(现金) for everything we bought. Now when we use a credit card(信用卡) to shop online, money is spent without us seeing it. That means we are already using digital(电子的) money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.    

When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. It's reported that people in Sweden completely stopped using cash last year, and the US might be next.

Bionic(仿生的) eye    

It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.

      A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data(数据) to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution(高清的) image could be just a few years away. 

Self-driving cars     

      Unlike a human driver, a self-driving car won't get distracted(分神) by a phone call, the radio or something outside the window. Sensors (探测器) and cameras on the car would allow it to stick strictly (严格地遵守)to the rules of the road and keep a safe distance from other cars. This would greatly reduce（减少） the number of road accidents. You could even take a nap while the car drives itself. In the future, driverless cars would be widely accepted.

    Every year on April 22, People all over the world celebrate Earth Day. It is a time to work to keep our earth clean. People plan projects to clean up the land, air and water.

    U.S. Senator Gaylord Nelson first thought of the idea for Earth Day in 1962 when he saw polluted rivers and cities with smoke. He needed to get support from Americans to clean up the earth. Finally, on April 22, 1970, 20 million Americans celebrated the first Earth Day! Now many countries around the world celebrate it, and you can, too.

    How can you celebrate Earth Day? Here are a few ideas:

    Join a clean-up project-Clean up your street or a favorite beach.

    Save energy-Turn off the lights when you leave a room, and use public transportation.

    Use less water.

    Reduce(减少)/ Reuse/ Recycle ― Practice the three Rs: First, reduce how much you use. Then reuse or recycle what you can.

    You can make a difference on Earth Day and every day!

EMERGENCY? WHAT EMERGENCY?

An emergency service (紧急服务) should be like that: a service that you phone in an emergency. You might need to call the police if you're in a car accident. But some people phone the emergency services for some unimportant reasons (原因). {#blank#}1{#/blank#}

Here are some examples we heard about from emergencycentres all over the world.

1 'I ordered food from a Chinese takeaway and it didn't come. I'm so hungry! Can you tell them to hurry up, please?'

2 'My children are making such a loud noise and I can't think about things. {#blank#}2{#/blank#}

3 There's a black cat in my garden. Black cats are such unlucky animals. Can someone please come and take it away?'

These calls are funny to read about, but they can have very serious consequences (后果) . 'Every call takes about a minute,' said one man who works in emergency services. 'Maybe that doesn't sound a very long time, but in that one minute, other people are calling who really have an emergency. And for them, a minute might be really important.'

So let's get really serious: {#blank#}3{#/blank#} And of course, remember that you should never phone them with information that's untrue!

第二节请结合第一节内容，回答下面的问题。

When can we call the emergency services? {#blank#}4{#/blank#}

 When you think of the sea, you may not think of Xinjiang or Inner Mongolia. But recently, the" seafood" produced in these places has become popular, especially after Japan put muclear- contaminated water(核污染水) into the sea, reported China Daily.

 In Nilka county(尼勒克县) in Xinjiang, about 6,000 tons of rainbow trout(虹鳟鱼) will be produced this year. Rainbow trout belongs to the same family as salmon(鲑鱼), which is a kind of well- known seafood. It tastes like salmon too.

 Why do farmers there choose to grow fish? The weather in some parts of Xinjiang is seldom hot, and the rivers are fed by meltwater(融水) from the Tianshan Mountains. Water deeper than 6 meters always stays at 10 C. As the meltwater is very clean and cold, it's a" comfortable" home for fish, Li Chunyu, a worker at a fish company in Xinjiang, told China Daily.

 To make sure the river stays clean, the company uses machines to clean fish waste in the water. They also use net cages(网箱) that are good for the environment. The net s are about 51 meters wide and lie 25 meters deep in the river.

 Meanwhile, in Inner Mongolia, whitele g shrimp(南美白对虾) grows well. Saline soil(盐碱土) covers a large part of the desert where few plants are able to grow. Farmers used to put water from the Yellow River onto the farmland to wash away the salt. This was a waste of salty water.

 Scientists then decided to create" seawater" with the salty water by adding in some other components. Whiteleg shrimps can live well in this kind of water. They taste no different from the same kind of shrimp that grows in the sea.
