China is running ahead in 5G. In March, 2019, the Shanghai Hongqiao Railway Station became the world’s first “5G railway station”. Now, it taken only 20 seconds to download(下载）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 will be much faster than today’s 4G networks!
The first 5G modern of the IT company Qualcomm supports speeds of up to 5 gigabytes per second(千兆每秒）. Most of us have never experienced anything close to that speed. And we are only talking about the first generation of 5G modern. Future moderns are likely to be even faster.
But 5G is not all about speed. Have you ever been to a large event where your data connection(数据连接）slowed down? That is because 4G networks can only support a certain number of devices(设备）per square kilometer. 5G networks will be able to do much better. They can support up to million devices per square kilometer.
Now, you begin to understand why 5G is a huge change over 4G. The technology is not just for the smart phones. It has a strong influence on every connected devices. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible. Wearable,
PCs, and smart home devices will be able to improve as well.
Are you looking forward to that 5G world now?
1.Which of the following is not mentioned about 5G?
A.The first “5G railway station” 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.How does paragraph 4show the advantage of 5G?
A.By using different advice on 5G networks
B.By comparing 5G with 4G
C.By showing some data of 5G networks
D.By listing some examples of 5G networks
3.How many fields(领域）of using 5G does the passage tell us?
A.Three
B.Four
C.Five
D.Six
4.What’s the best title for the passage?
A.What’s 5G?
B.Is 5G Good or Bad?
C.How is 5G used?
D.How’s the future life?
【答案】D；B；C；A
D
When Carlos Westez died at the age of 76, a language died, too. Westez, more commonly known as Red Thunder Cloud, was the last speaker of the Native American language. Catawba.
Anyone who wants to hear the songs of the Catawba tribe（部落）can get in touch with the Smithsonian Institution in Washington, D.C., where Red Thunder Cloud recorded a series of songs for future generations back in the 1940s. They are all that is left of the Catawba language. The language that people used to speak is gone forever.
We are know the damage that modern industry can do to the world’s ecol ogy(生态).However, few people know the effect（影响）that widely spoken languages have on other languages and ways of life. English has spread all over the world. Chinese, Spanish, Russian, and Hindi have become powerful languages, as well, As these language become more powerful, their use as tools of business and culture increase. When this happens, hundreds of languages that are spoken by only a few die out.
Experts believe there are about 6,000 languages around the world, but more than half of them could die out within the next 100 years. Araki is a native language of the island of Vanuatu, located in the Pacific Ocean. It is spoken by only a few older adults，so like Catawba，Araki will
soon disappear. Many languages of Ethiopia will have the same situation because each one has only a few speakers.In the Americas, 100 languages also are dying out.
Red Thunder Cloud was one of the first to recognize the threat of language death and to try to do something about it. He was not actually born into the Catawba tribe, and the language was not his mother tongue. However，he was a usual visitor to the Catawba reservation in South Carcinoma, where he learned the language.The songs he sang for the Smithsonian Institution helped to make Native American music popular. Now he is gone, and the language is dead.
1.Why did Westez record songs for the Smithsonian Institution?
A.To fight for Americans' ecology.
B.To protect the Catawba language.
C.To make native American music popular.
D.To help young people learn Catawba songs.
2.Which of the following led to the disappearance of Catawba?
A.Widely spoken languages.
B.Death of Carlos Westez.
C.Ways of life.
D.Modern industry.
3.Which of the following statements is TURE?
A.Catawba language died in the 1940s.
B.Chinese has spread all over the world like English.
C.More than half of the languages around the world have died out.
D.Many languages of Ethiopia will probably soon disappear.
4.What can we learn about Red Thunder Cloud?
A.He was the only one to realize the threat of language death.
B.He was born in the Catawba tribe.

【物理】杭州市公益中学九年级上册期中精选试卷检测题 一、初三物理电流和电路易错压轴题（难） 1．演绎式探究﹣﹣﹣探究点电荷的电场强度 如果带电体间的距离比它们的大小大得多，这样的带电体可以看成是点电荷． （1）实验发现，带电量分别为q1、q2的两个点电荷距离为r时，它们之间的作用力 F=k，其中k为常量，当q1和r一定时，F与q2之间的关系图象可以用他图甲中的图 线来表示． （2）磁体周围存在磁场，同样，电荷周围也存在磁场．电场对放入其中的电荷产生电场力的作用．点电荷q1和q2之间的作用力实际是q1（或q2）的电场对q2（或q1）的电场力．物理学中规定：放入电场中某一点的电荷受到的电场力F跟它的电量q的比值，叫做该点的电场强度，用E表示，则E= ． 如图乙所示，在距离点电荷Q为r的A点放一个点电荷q，则点电荷q受到的电场力 F= ，点电荷Q在A点产生的电场强度E A= ． （3）如果两个点电荷同时存在，它们的电场会相互叠加，形成合电场．如图丙所示，两个互成角度的电场强度E1和E2，它们合成后的电场强度E用平行四边形的对角线表示．如图丁所示，两个点电荷Q分别放在A、B两点，它们在C点产生的合电场强度为E合．请推导 证明：E合=． 【答案】（1）c；（2）；；；（3）证明过程如上所示 【解析】 试题分析：（1）作用力为F=k，k是常数，q1和r一定时，F与q2成正比，所以是一条过原点的直线，c符合题意；（2）根据题意，电场强度：E=；Q在A点对q的电场力：F=，所以点电荷Q在A点产生的电场强度：E A=/q=；（3）由题意知，AB在C点电场强度的大小相等，E A=E B=，且互相垂直，做出其合场强，如图所示：

无解. 故甲班第一次购买8千克，第二次购买22千克 【解析】【分析】（1）根据20kg以上每千克的价格为8元可求出乙班付出的钱数，从而可求出乙班比甲班少付出多少．（2）设甲班第一次购买x千克，第二次购买30-x千克，则需要讨论①x≤10，②10＜x≤15，列出方程后求解即可得出答案． 3．已知数轴上A.B两点对应的数分别为?4和2，点P为数轴上一动点，其对应的数为x. （1）若点P到点A.点B的距离相等，写出点P对应的数； （2）数轴上是否存在点P，使点P到点A.点B的距离之和为10?若存在，求出x的值；若不存在，请说明理由； （3）若点A点B和点P(点P在原点)同时向右运动,它们的速度分别为2、1、1个长度单位/分,问：多少分钟后P点到点A点B的距离相等?(直接写出结果) 【答案】（1）解：∵A、B两点对应的数分别为?4和2， ∴AB=6， ∵点P到点A. 点B的距离相等， ∴P到点A. 点B的距离为3， ∴点P对应的数是?1 （2）解：存在； 设P表示的数为x， ①当P在AB左侧，PA+PB=10， ?4?x+2?x=10， 解得x=?6， ②当P在AB右侧时， x?2+x?(?4)=10， 解得：x=4 （3）解：∵点B和点P的速度分别为1、1个长度单位/分， ∴无论运动多少秒，PB始终距离为2， 设运动t分钟后P点到点A. 点B的距离相等， |?4+2t|+t=2， 解得：t=2 【解析】【分析】（1）根据点P到点A、点B的距离相等，结合数轴可得答案；（2）此题要分两种情况：①当P在AB左侧时，②当P在AB右侧时，然后再列出方程求解即可；（3）根据题意可得无论运动多少秒，PB始终距离为2，且P在B的左侧，因此A也必须在A的左侧，才有P点到点A、点B的距离相等，设运动t分钟后P点到点A、点B 的距离相等，表示出AP的长，然后列出方程即可.

【答案】D C D B Huw Thomas fell in love with Megan. But then an accident changed his life, and he had to move to Canada. Megan promised to write to him. But Huw never heard from her… until one day a letter arrived. He saw the letter came from where he and his father had lived in their early years. Who was writing to him? He turned the envelope(信封) over in his hands several times. Then he took out the letter and read: Dear Huw, I don’t know if this letter will reach you, and I don’t really know why I’m writing to you after all these years, but… Huw turned to the end of the letter and saw: Best wishes, Megan He couldn’t believe it. He turned back to th e first words of the letter and read: … after all these years, but I’ve just found your letters to me from Canada. Believe me, this was the first time I’d read them and they made me cry, even after 50 years. I found them in a box of my father’s papers. The y were never opened. Huw, I never knew that you’d written to me. I thought your new life in Canada had made you forget me. Now I realize that my father kept your letters. I can still remember asking him if there was any letter for me, and he always said “___________, my girl. I told you he was no good.’’ Finally, after about a year, I believed him. But why did he keep the letters? Do you think he wanted me to find them when it was too late? Anyway, he’s dead now, so I can’t ask him. All I can say is I’m sorry. Sorry for what my father did, sorry that you never heard from me and sorry for…everything. I hope that at least this letter reaches you. Of course, I’ll understand if you don’t want to write back to me, but if you do, I am still Megan Jenkins, and I still live at the same address. Best wishes, Megan Huw read the letter again. Everything with Megan came back to him. He had never
