A lot of earthquakes happen in the world every year. Why do earthquakes happen? Scientists tell us the outside of the earth is made of a number of different plates(板块). The plates move very slowly. Sometimes they stop and don’t move for a long time. When some of the earth’s plates move suddenly, an earthquake happens.

Many earthquakes happen under the sea. Sometimes they happen near mountains. In fact, earthquakes may happen anywhere on the earth. During an earthquake, the shakings make rocks rise suddenly and even break open. Houses fall. People are killed or hurt. Sometimes whole villages or cities are destroyed.

Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and made maps that show “earthquake belts”. In the areas in these belts, it’s possible for earthquakes to happen. In these areas we can make houses strong enough to stand against earthquakes.

In the future, scientists will be able to predict(预言) exactly when and where an earthquake will happen. They can tell us what to do and how to do it as well.

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction ( and heat) you can make. Let’s discover friction!

WHAT YOU’LL NEED:·Soap ·Water· Your hands!

WHAT TO DO:

1. Make sure your hands are dirty.

2. Rub your hands together until you feel the heat of your hands.

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 10-30 years from now, according to the BBC.

Bionic（仿生的）Eyes

They are no longer something, only in a science fiction movie. People who are blind may have a chance to see things clearly—by wearing bionic eyes.

A blind eye can no longer sense sight, but a bionic eye can use a camera to “see” the environment and send information to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A bionic eye with very clear pictures could be just in a few years away.

Digital Money

We used to pay with cash for everything we bought. Now we can use Wechat Pay or Alipay to shop, money is spent without seeing it. That means we are already using digital money. People only need to take a mobile phone wherever they go. Using these ways is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.

It is reported that people in Sweden completely stopped using cash last year, and the US might be the next.

Self-driving Cars

Unlike a human driver, a self-driving car won’t be influenced by a phone call, the radio or something outside the window. Sensors（探测器）and cameras on the car would allow it to follow the rules of the road strictly and keep a safe space from other cars. This would greatly make the number of road accidents smaller. You can even take a short rest while the car drives itself. In the future, driverless cars would be widely accepted.

1.Which of the following payments is not mentioned in this passage?

A.Cash B.Wechat Pay C.Alipay D.Credit card

2.Bionic eyes send information to the________.

A.mind B.camera C.computer D.heart

3.From the report, we can learn some information about________.

A.industry and farming B.traffic and journey

C.science and technology D.culture and art

4.The passage tells us that________.

A.bionic eyes only appear in the science fiction films

B.the blind wearing bionic eyes may see clearly in the future

C.self-driving cars will be influenced by something outside

D.there will be no accidents at all if self-driving cars are used

5.We can infer（推断）that________ from the passage.

A.there would be a number of self-driving cars on the road B.robots would control the world

C.the blind could use glasses to see things around D.we would live a hard life with digital money
