Scientists are trying to find new clean energies, so that they do not pollute the environment. Solar power(太陽能)is one of them.

Solar power is a kind of electricity.It takes energy from the sun by using solar panels(太陽能金屬板).People usually put the solar panels on the roofs of the houses and buildings.It is the family solar power system. Some countries are even beginning to build solar power factories by setting thousands of solar panels in some place, because there is enough sunshine. Solar power panels have many advantages. The power is easy to get and will never be used up. Whenever it is sunny, there is power. The power is clean and renewable. It helps to reduce waste and pollution.It is also great for the environment. In some places,because they are too far away to send electricity or not easy to build electric power factories, solar power is especially necessary.

More and more countries,such as China, the USA,Japan and India, encourage scientists to develop technology to put solar power into use. However, the power is not as widely used as expected（預期的）.

One of the difficulties is that a solar power system needs sunshine. Some countries having lots of rain, like the UK, are not suitable to develop such power systems. Secondly,a solar power factory requires a very large place to set enough solar panels to collect sunlight and change it into electricity. Maybe an area in the desert would be one of the perfect places for such a factory to build. What’s more, solar panels are expensive at present though the energy itself doesn’t cost anything.

Today scientists are working hard to develop cheaper solar power systems. Maybe one day solar power will be one of the most important clean energies in our life.

China is running ahead in 5G . In March, 2019, the Shanghai Hongqiao Railway Station became world's first "5G railway station". Now, it takes only 20 seconds to download a long movie there.

We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G, after all? At first, 5G is fast. 5G will be much faster than today's 4G networks!

The first 5G modem（貓，調(diào)制解調(diào)器）of the IT company Qualcomm supports speeds of up to 5 Gigabytes（千兆字節(jié)）per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation（一代）of 5G modems, Future models are likely to be even faster.

But 5G is not all about speed. Have you ever been to a large event where your data (數(shù)據(jù))connection slowed down? That is because 4G networks can only support a certain number of devices(設(shè)置) per square meter. 5G networks will be able to do much better. They can support up to a million devices(設(shè)置) per square kilometer.

Now, you begin to understand why 5G is a huge change over 4G. The technology is not Just for the smartphones. It has a strong influence(影響) on every connected device. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible. Wearables, Pcs and smart home devices will be able to improve as well.

Are you looking forward to that 5G world now?

1.Each of the following is mentioned about 5G EXCEPT

A.the first place where 5G is used in the world

B.the speed of using 5G to download

C.the country that runs ahead in 5G

D.the way of 5G spreading

2.Paragraph 4 shows the advantages of 5G by_________

A.using different advice

B.comparing 5G with 4G

C.some data of 5G networks

D.the condition of different areas

3.How many fields of using 5G does the passage tell us?

A.Three. B.Four C.Five D.Six.

4.From the passage, which of the following is WRONG?

A.5G technology is closer and closer to us.

B.5G self-driving cars will be cheaper than any other cars.

C.IT company Qualcomm produced the first generation of 5G modems,

D.5G networks can support up to a million devices every square kilometer.

5.What's the best title for the passage?

A.What's 5G? B.How is 5G used?

C.Is 5G good or bad? D.How's the future life?
