广东省深圳市龙岗区2018-2019学年八年级下学期英语期末考试试卷

阅读短文,从下面每小题的A、B、C、D四个选项中选出最佳选项。

    If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G.The "G" stands for the "generation (代)" of your mobile phone network. But these symbols will become things of the past after 5G networks fully arrive.

    On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.

    About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won't just bring faster mobile Internet. People can use it to do many other things as well.

    For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag (延迟). When the car "sees" an obstacle (障碍物), it sends he information to a data center and receives instructions. However, it takes time to send and receive the information with this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer according to CNN.

    5G could also be used to power the Internet of Things (IoT). This means a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your fridge could automatically (自动地) place an order online for eggs when it finds that there are no eggs left.

(1)、In which city was 5G tested for the first time in China?
A、Beijing B、Shanghai C、Guangzhou D、Shenzhen
(2)、The writer uses self-driving cars as an example to ________.
A、explain how self-driving cars work B、tell us the possible danger of self-driving cars C、let us know how helpful 5G's fast speed can be D、show us how 5G will bring faster mobile Internet
(3)、Which of the following statements is TRUE according to the passage?
A、The first 5G video call was made on a computer on March 30. B、With the help of 5G, people can only download and upload data faster. C、Self-driving test cars might not crash if they can receive instructions in time. D、The IoT is a fridge that can order eggs automatically when there are no eggs left.
(4)、The passage mainly talks about ________.
A、the IoT B、5G networks C、self-driving cars D、Huawei smartphones

In 1987 a small company named Huawei was started in Shenzhen. After more than 30years of development , the company has now beaten Apple and become the world's second largest maker of smartphones. It has also be-come the world's largest supplier(供应商)of 5G. 

But recently, Huawei faces some difficulties. The US government made a law to stop its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the US government stopped selling parts and services to Huawei. They believed that Huawei's business would be hurt this way. 

"We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information, " Ren Zhengfei, Huawei's president said. "The law would have little effect on our company. Huawei has enough ability to deal with the problems, " Ren added. 

In an interview(采访) several years ago, Ren Zhengfei said, "I started Huawei with only£ 4, 000 at the beginning, but now it has be-come a $ 100 billion company. The experience was not as romantic as you imagine. "

Facing the law of the US, Huawei is growing. Huawei's smartphone sales around the world rose 50 percent compared with a year earlier in the first three months of 2019. So far, Huawei has grown into the world's largest telecommunication equipment supplier(电信设备供应商), selling in 170 countries! It may beat Samsung as the largest smart phone maker in the near future.

People pay close attention to 5G these years. So, what is 5G? The "G" stands for(代表) the generation of your mobile network.5G is the 5th generation mobile networks and it's a hundred times faster than 4G.

The first 5G video call was made on a Huawei Mate X smartph one on March 30, 2019. Shanghai has also become the first city in China to start testing 5G networks. Monaco became the first country in Europe to use a next-generation 5G mobile phone network based on technology from Chinese company Huawei.

It sounds obvious, but it's important to understand just how much faster 5G is compared to current 4G speeds. 5G will not only be many, many times faster than your existing connection, and it will be greatly faster than the broadband connection you have at home.

Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less. This big change will not only make our mobile Internet faster. It can be used in many other ways as well.

For example, 5G will help make self-driving cars safer. Today's self- driving test cars have one problem—lag. When the car "sees" an obstacle(障碍), it sends this information to a data centre and receives instructions. However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN. 5G could also be used to power the Internet of Things (IOT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your fridge could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.

All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen. Though we've seen a lot of positive progress just in the last year, we still have a long way to go before 5G is anywhere near as common as 4G is right now.

 根据短文内容,选择最佳答案。

①Zhang Guimei, a teacher in the mountainous area of Yunnan, set up a free high school for girls with support from the Communist Party of China(中国共产党) and local government. Around 2,000 girls from poor families who went to the school went on to study at various universities. In the past 10 years, the Party of China and government have worked hard to make sure all children can receive an education. One way to help fill the educational gap(差距) between urban and rural areas is the use of 5G and other new technologies. 

②Guizhou Normal University has worked with Huawei to set up a "5G+ rural education" laboratory and taught "5G+ rural education" courses online. English, music, art, science, biology, and other high-quality courses were provided to rural schools in the area through the platform(平台). A high school in Guizhou started the "5G rural education" project in October 2021. More lively and interesting courses can improve students' interest in learning and teaching quality.

③According to Yu Minhong, a member of the National Committee of the Chinese People's Political Consultative Conference(中国人民政治协商会议全国委员会), in the future, a widely applied 5G network will reduce the cost of educational information in primary and secondary schools in rural and remote (偏远的) areas.

④Thanks to the effort from all sides, 5G technology does shorten the educational gap. With the development of technology, it's not a dream for students even in remote areas to receive high-quality education.
