Many years ago，people depended on the sun，the moon and stars to find their way around. Later，the compass was introduced. And now，we have satnav(卫星导航)systems to guide us.

A satnav system uses groups of satellites to show the user's location. They send information to the receiver，such as a smart phone，to show us where we are.

The earliest built satnav system is the Global Positioning System(GPS)，which belongs to the US. Then there is Russia's Global Navigation (导航) Satellite System(GLONASS)，the European Union's Galileo and China's own satellite navigation system—BeiDou.

On October 14，2017，an ARJ21­700 plane，which was the first plane　 made in China，with the BeiDou navigation system，successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced abroad，according to the Commercial Aircraft Corporation of China.

Since its introduction in 2000，the BeiDou navigation system has seen　 an increasing number of applications linked to everyday life，from shared bikes to farming. For example，smart locks with BeiDou chips make it easier to find a bike. Farmers can use BeiDou to help plow(犁)the soil and sow seeds. BeiDou's farming applications have spread　 to most parts of China.

With its many uses，the Beidou navigation system is even playing a big role in the Belt and Road Initiative(一带一路).“To date，the BeiDou system has covered most parts of the Asia-Pacific area”，said the main designer of the BeiDou system.

Today，there are more than 20 BeiDou satellites above the earth，and China plans to send even more this year to expand(扩展)the BeiDou network to better serve the Belt and Road Initiative. As BeiDou expands abroad，it will be increasingly popular in the logistics(物流)industry.

1.What is the purpose of the first three paragraphs?

A.To tell us something about GPS.

B.To show us the benefits of satnav systems.

C.To tell us how satnav systems were made.

D.To tell us about some satnav systems and how they work.

2.The underlined phrase “the system” refers to “______”.

A.the Global Positioning System

B.the Beidou navigation system

C.the European Union's Galileo

D.Russia's Global Navigation Satellite System

3.According to the article，the BeiDou navigation system is already widely used ______.

Many years ago, people relied on the sun, the moon and stars to find their way around. Later, the compass (指南针) was introduced. And now, we have satnav (卫星导航) systems to guide us. A satnav system uses groups of satellites to show the user’s location. They send information to a receiver, such as a smart phone, to show us where we are.

The earliest built satnav system is the Global Positioning System, which belongs to the US. Then there is Russia’s Global Navigation (导航) Satellite System, the European Union’s Galileo and China’s own satellite navigation system, BeiDou.

On October 14, 2017, an ARJ21-700 plane, which was the first domestically-produced jet (国产喷气式飞机) equipped with the BeiDou navigation system, successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced aboard, according to the Commercial Aircraft Corporation of China.

Since its introduction in 2000, the Beidou navigation system has seen increasing numbers of applications linked to everyday life, from shared bikes to farming.

When it comes to shared bikes, smart locks that support BeiDou chips offer more accurate positioning than others, making it easier to find a bike.

Farmers can use BeiDou-enabled tractors to plow (犁) the soil and use unmanned aircraft with BeiDou to sow seeds, which can improve efficiency and make better use of resources. BeiDou’s farming applications have spread from Heilongjiang province to Beijing, Liaoning, Shanxi, Hubei and other regions across China.

With its many uses, the Beidou navigation system is even playing a big role in the Belt and Road Initiative (一带一路). “To date, the BeiDou system has covered most parts of the Asia-Pacific region (地区), as well as countries along the Silk Road Economic Belt and the 21stCentury Maritime Silk Road” said Yang Changfeng, Chief designer of the BeiDou system.

Today, there are more than 20 BeiDou satellites above our heads, and China plans to launch even more this year to expand the BeiDou network to better serve the Belt and Road Initiative.

“As BeiDou expands its overseas reach, it will be increasingly popular in the logistics (物流) industry,” said Miao Qianjun, secretary-general of the navigation services association. “Ships, for example, can use it to position themselves while sailing across oceans to European countries, no longer limited to Southeast Asian regions in the near future.”

1.What is the purpose of the first two paragraphs?

A.To compare some modern satnav systems.

B.To describe the benefits of satnav systems.

C.To tell us how satnav systems were created.

D.To introduce some satnav systems and how they work.

2.What can we know about the BeiDou navigation system according to the article?

A.It was used successfully in a new jet plane.

B.It is more powerful than other satnav systems.

C.It was introduced into China on October 14, 2017.

D.It wasn’t used in our everyday life until recently.

3.According to the article, the BeiDou navigation system is already widely used for _________.

A.plowing the soil and sowing seeds

B.improving the efficiency of networks

C.producing more smart locks for shared bikes

D.navigating ships across oceans to European countries

4.What is Miao Qianjun’s attitude toward the future of the BeiDou system?

Many hundreds of years ago, the moon was a mystery to people on the earth. What was that glowing ball came out at night? Why did it keep getting smaller, then larger? Why didn’t it fall from the sky? Through the ages, people have tried to come up with answers.

To the native people of Bolivia, in South American, the moon was a great chief who once lived on the earth. The Abaluyian people of Kenya, in Africa, believe the moon and the sun were brothers who fought in the sky. In other parts of the world, people believed they saw different pictures in the moon. The Haida Indians of Canada saw a woman carrying a bucket. The Chinese saw a road.

People in the past also used the moon to mark time as a kind of calendar. In fact, in some languages, the word for moon meant “month”. A Native American nation called the Sioux made a calendar of 13 moons, or months. Each moon had a name, such as Moon of Black Cherries, Moon of Green Corn, and Moon of Severe Cold.

Though people of the past found the moon was helpful, mysterious and interesting, they didn’t know much about it. They only knew what they could see with their own eyes.

Then almost 400 years age, an Italian scientist named Galileo made a new telescope(望远镜) that was more powerful than any telescope made before. Galileo decided to take his new implement to look at the moon. He discovered that the moon was not the smooth, shiny ball. The brighter places were mostly hills and mountains. The flat areas were lower, which is why they appeared darker.

As more people saw the moon through telescopes, they discovered more about it. Yet, people still had much to learn about the moon.

1.Which name of the moon is NOT mentioned in the passage?

A.Moon of Severe Cold.　　　　 B.Moon of Red Trees.

C.Moon of Black Cherries.　　　 D.Moon of Green Corn.

2.The underlined word “implement” probably means .

In the past, many people depended on horses for transportation(运输), farming and other kinds of work. Nowadays a lot of people still like to ride horses. So it is not surprising that many expressions about it are still used by Americans today.

In politics, a "dark-horse candidate" is someone who is not well known to the public. Sometimes, a dark horse unexpectedly wins an election(选举).

Another piece of advice is "do not change horses in midstream." You would not want to get off one horse and on to another in the middle of a river. Or make major changes in an activity that has already begun.
