    There has been a lot of publicity (宣传) recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?

What is 5G?

5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. These systems are wireless computer networks. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity. The new 5G system promises more of the same. It is expected to permit more users to do more things-at a faster rate. Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other “G” versions.

When will it be available?

Before we can all use 5G, wireless companies and phone makers will have to complete and deploy (部署) a whole new system. New phones and communication equipment must be built. American wireless companies have been preparing for the new system for some time. They have been creating new network equipment and buying broadcasting space to carry 5G signals. They have built news G antennas(天线)to serve American cities and towns. Wireless providers will invest at least $275 billion n 5G-related networks in the United States, the industry group CTIA reported. The first U.S, launch of 5G is expected to happen sometime this year. Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.

1.Which system is widely used nowadays?

A.5G. B.2G. C.3G D.4G.

2.Which of the following is NOT 5G system’s advantage to the other Gs?

A.It will allow more users to do more things. B.The internet speed will be much higher.

C.The users will spend much less money on it. D.It will affect more devices and industries

3.What can we learn from the last paragraph?

A.5G system has nothing to do with phone makers.

B.There is much work to do before 5G comes into use.

C.New phones will be much smarter than those used now.

D.4G system will be stopped as soon as 5G comes into use.

4.In which order will the following countries use 5G system according to the passage?

A.USA→China→European nations. B.China→USA→European nations.

C.USA→European nations→China. D.European nations→China→USA.

 

1.D 2.C 3.B 4.A 【解析】 这是一篇说明文。文章主要介绍了世界上的下一代无线技术——5G,解释了什么是5G,5G的一些优势以及何时可以投入使用的问题。 1. 推理判断题。根据第三段中5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system.可知5G代表第五代,意味着技术进步的下一步将取代目前的4G系统。由此可推知,目前广泛使用的是4G。故选D。 2. 细节理解题。根据第三段中It is expected to permit more users to do more things-at a faster rate. Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other “G” versions.可知它有望允许更多的用户以更快的速度做更多的事情。更高的网速和更大的网络容量将为连接到5G的设备用户带来更好的性能。然而,技术专家表示,5G与早期系统有一个主要的不同之处。与其他“G”版本相比,它将远远超越移动网络技术,影响更多的设备和行业。由此可知,5G系统相对于其他系统的优势有它将允许更多的用户做更多的事情、网速将会高得多以及它将影响更多的设备和行业,除了C选项“用户在这上面花的钱会少得多”文章没有提到。故选C。 3. 推理判断题。根据最后一段中Before we can all use 5G, wireless companies and phone makers will have to complete and deploy (部署) a whole new system. New phones and communication equipment must be built. (在我们都能使用5G之前,无线公司和手机制造商必须完成并部署一套全新的系统。必须制造新的电话和通讯设备)以及后文Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.可知行业专家预计还需要几年时间才能推广到全国。农村地区将需要更长的时间。中国预计将在2020年的某个时候推出5G,而随着时间的推移,欧洲国家可能会放慢其系统的建设速度。由此可推知,在5G投入使用之前还有很多工作要做。故选B。 4. 细节理解题。根据最后一段中The first U.S, launch of 5G is expected to happen sometime this year. Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.可知在美国,5G预计将在今年的某个时候推出。行业专家预计还需要几年时间才能推广到全国。农村地区将需要更长的时间。中国预计将在2020年的某个时候推出5G,而随着时间的推移,欧洲国家可能会放慢其系统的建设速度。由此可知,5G系统的使用顺序为:美国→中国→欧洲国家。故选A。

    A 3-year-old boy who was lost in the woods is now safe at home with his family. But Casey Hathaway told his rescuers that he was not alone in the rainy, freezing cold woods. He said he was with a friend—a bear.

The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina. When the other children returned to the house and Casey did not, the family searched the area for almost an hour before calling the police. Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still-no Casey.

    “Food is the first necessity of the people” is a famous Chinese old saying, which reflects that Chinese have paid much attention to food since the ancient times. The importance of food in people’s daily life in China can be seen in the way they send greetings to each other, “Have you eaten?”, which is far away from the way people greet in western countries and has been seen as a characteristic of Chinese culture.

Food in China generally includes rice, wheat, buckwheat, corn, potato, sweet potato, beans and varieties of vegetables. Besides, wheaten food such as Mantou (steamed bun), noodle, Youtiao (deep-fried dough stick), Xiaolongbao (steamed pork-stuffed dumpling in bamboo basket), and: many other local snacks, are commonly seen on the table in China.

Regionally, a general feature of spicy east food, sweet south food, sour west food and salty north food can be summarized, but flavors of food in places differ from each other as a matter of fact. Generally, people living in South China pay more attention to nutrition and prefer delicate, tasty and refreshing food such as rice porridge and soup; however, spicy hotpot is always people' s favorite in the southwest areas due to the wet and rainy climate. And, people living in North China prefer wheaten food such as Jiaozi, noodles, while all kinds of steamed bun and beef and mutton are most popular in northwest areas.

A friend of mine whose name was John Smith had a bad memory, which made him famous. He was so forgetful that he sometimes forgot what he was talking about in the middle of a sentence. His wife had to constantly( 经常地)remind him about his meetings, his classes, even his meals! Once he forgot he had eaten breakfast twice, at home and at school. His wife liked to remind her neighbors, “If John didn’t have his head tied on, he would forget that too!” Since Smith was a professor at a well-known university, his forgetfulness was often an embarrassment to him. It wasn’t that he was not clever, as some critical people tended to say, but just very, very absent-minded.

One hot summer day, Pro.Smith decided to take his children to a seaside town about a three-hour train ride away. To make  the trip more interesting for his young children, he kept the name of the town a secret. However, by the time they arrived at the station, Smith forgot the name of the town he was planning to visit.  luckily, a friend of his happened to be in the station. He offered to take care of the children while Smith hurried back home to find out where he was going.

The professor’s wife was surprised to see him again so soon.

“Oh, my dear, I forgot the name of the town.”

“What? You forgot the name? Maybe one day you will forgot my name! Now I’ll write the name of that town on a piece of paper, and you put it in your pocket and please, please don’t forget where you put it.”

Satisfied that she had solved the problem, she sent her husband off again. Ten minutes later she was astonished to see him outside the house for the third time.

Paragraph 1:

        “What is the matter now?” asked his wife._________________________________________________________________________________________________________________________________________________________________________________________________________________________________

         Hearing the cry, out rushed their neighbors, trying to find out what had happened. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________
