Dear Nancy's parents，
My daughter had a bullying （欺凌） problem a couple of years ago． It wasn't easy，but I ended it．When things are a serious as you describe， it is no time to be silent． These kids probably know each other from school， so take the rude text messages sent by the bully directly to the headmaster and show him Describe to him bow it is affecting your 13﹣year﹣ old daughter．Tell him you will not stand it and you want him to put an end to it now．
Bullying is a dangerous and serious offensethese days，and any good headmaster will take your charges seriously． He will probably address the issues with the parents． If they are crappy parents， then they may do nothing to their child． You may have to repeat this process several times， but you need to keep a check on those text messages and don't allow your child to delete them．
Now is the time to draw your child close and take care of her， because she needs it． My daughter did not like me being involved（参与的）either， but you are the only hope she has of solving this problem， so do it and mean business．Always be polite but straightforward．The headmaster and the parents must know you mean business．
If repeated meetings with the headmaster （and parents， if he allows it） does not solve the problem， then I would consider hiring a lawyer． That will send the message across loud and clear．When you are talking about financial loss， most parents will stand up and take notice and act to keep their kid under control!
Good luck ﹣ I wish you the best in this terrible situation．
Yours，
Rachel

Today， the world's diversity（多样性） of food crops is quickly decreasing． But scientists around the world are taking action． They are building seed banks． At seed banks， scientists store the seeds of many different crops．
There are now 1，400 seed banks around the world． However， some banks are in warm countries． If the electricity fails， the seeds will get too hot and die．Other seed banks are in countries troubled by war．Sometimes people damage the seed banks． If this happens， valuable seeds can be lost forever!
The organization Global Crop Diversity Trust decided they wanted to deal with this problem．So， they decided to build a global seed bank． This seed bank would contain a back﹣up， or extra copy，of all the world's seeds． Smaller seed banks would still collect and keep local seeds．But they would also send copies of their seeds to the global bank．
Scientists from the Global Crop Diversity Trust chose the cold，snowy mountains of Svalbard，Norway to build the global seed bank ﹣ the Svalbard Global Seed Vault． Organizations， farmers， or local seed banks store their extra seeds there． And the people who place their seeds in the vault are the only people who can take them out． They pay to ship their seeds to Norway， but it does not cost them any money to store their seeds． The Global Crop Diversity Trust pays for this．
Cary Flower is a scientist who heads the Global Crop Diversity Trust． He said， "If the Seed Vault simply supplies seed banks with copies of sees that those banks lost by accident， the Seed Vault will be worth way more than it cost．"

The traditional Chinese lunar calendar divides the year into 24 solar terms．Grain Rain（谷雨），as the last term in spring， starts on April 19 and ends on May 4．
Grain Rain comes from the old saying， "Rain brings the growth of hundreds of grains"，which shows that this period of rainfall is very important for the growth of crops．Here's something that you may not know about the Grain Rain．
|
1． Grain Rain falls between the end of spring and the beginning of summer，and the temperature rises much higher than it does in March． With dry soil and heavy winds， sandstorms may happen more often． |
|
2． There is an old custom in southern China that people drink tea on the day of Grain Rain． Spring tea during Grain Rain is good for the eyes． It is also said that drinking tea on this day would prevent bad luck． |
|
3． People in northern China have the tradition to eat the vegetable toona sinensis during Grain Rain． An old Chinese saying goes "loona sinensis before the rain is as tender as silk"． The vegetable is good for the stomach and skin． |
|
4． The Grain Rain Festival is celebrated by fishing villages in northern China． Grain Rain marks the start of the fishermen's first voyage of the year． The custom dates back to more than 2，000 years ago． |

How has technology made your life easier？ When you go to a shopping mall， you can enjoy free Wi﹣Fi there． When you want to take a taxi， you can book one with your phone． In fact， all of these things can be seen in a smart city．
The idea of a smart city was first suggested by tech company IBM in 2010．Generally，a smart city is a city that uses digital technology， such as 5G network and the"internet of things"， to save money and energy， and make our lives more convenient．
Cities like Boston， Amsterdam and Copenbagen are already using smart technology to improve public services． In the US cities of Boston and Baltimore， smart dust bins can sense（ 感知） how full they are and tell workers when they need to be cleaned．In Amsterdam，traffic is monitored and changed according to real﹣time data collected from sensors around the city． There are fewer traffic jams．
Smart cities will allow us to save energy． By using sensors and 5G networks to check the usage of water， gas and electricity， city managers can find out how to use these energy better． For example， water and gas pipes（管道） could remind repair workers when there is something wrong． Air pollution could be more closely monitored， too．
What's more， telehealth is used with the help of 5G． Telehealth means caring for patients from far away when the provider and the patient are not in the same place．
One form of this is video meeting with a doctor in real time， the same to a WeChat video call． It will also give older people or those living in the countryside an easier way to see a doctor． There are many exciting apps for 5G tech in medicine． One of them is far﹣away operations． In March， China's first 5G﹣based brain operation was done by a doctor in Sanya，Hainan，who operated on a Parkinson's patient in Bejing．In August， China Daily reported that robots in Beiing performed three operations in Xinjiang，Tianjin and Zhangjiakou at the same time．
Of course， it will take time to build the smart cities of the future． But since we've already seen successful examples， it won't be long until more cities join in． Tech Republic believes that by 2050， about 60 percent of people worldwide will live in smart cities．
根据上文内容判断正（T）误（F）
（1）From the examples of smart cities， we know that it won't be so crowded in the future． ____
（2）From the passage we learn about three fifths of cities will be turned into smart cities by 2050．
（3）Because of 5G networks and sensors， workers can check and monitor public services in time in smart cities．
（4）People who live in the countryside can see a doctor by telehealth．
（5）A doctor did three operations with the help of 5G at the same time．
New trains run across rocky mountains and the Great Wall to the north of Beijing like bullets（ 子弹）．They run on a high﹣speed railway line between Beijing and Zhangjiakou． The opening was on Dec 30，2019．
The railway is an important support project for the 2022 Winter Olympics． The 174﹣km railway's trains move at a top speed of 350 km/h． This reduces the travel time between Beijing and Zhangjiakou， the Winter Games will be held there， from over three hours to only 47 minutes． It has 10 stops in total．It will help improve tourism． There are places of interest nearby．
Some of the trains on this railway are smart trains that can run by themselves．
With the help of the Beidou Navigation Satellite System， they can automatically（ 自动）start， run between stations， change their timing according to the time table， correctly stop at a station， and open and close their doors． Passengers can also watch live sports programmesduring the Winter Olympics on the train， which is helped with 5G technology．
Some people consider Zhan Tianyou as "the father of China's railways"． Who is Zhan Tianyou？ In 1872， the Qing government chose 30 young boys to be sent to the US to study．They were the first students in Chinese history to study abroad． Zhan Tianyou was one of them．After graduating from Yale University， Zhan came back to China． In 1905， the Qing government decided to build a railroad between Beijing and Zhangjiakou． Zhan， who studied engineering， led the project． The project is best known for its Y﹣shaped switchback（人字形坡路）．There are many mountains along the Being ﹣Zhangjiakou railway． It was difficult for trains to climb the mountains．
He led construction（建设）on the old Bejing Zhangjiakou railway， China's first independently ﹣designed railway． It was not possible to build a railway without foreign help at that time． But Zhan， the head engineer of the railway project， insisted（坚 持） that it could be done． Zhan came up with an idea to reduce the slope（坡度）：a Y﹣shaped switchback．Instead of going directly from A to B along a steep（ 陡的）slope， the train goes from A to C first and then from C to B． This makes the slope much less steep．
After many difficulties． the Beijing﹣Zhangjiakou line went into operation in 1909． Its trains ran at 35 km/h．
As President Xi Jinping said， the Beijing﹣Zhangjiakou railway stands for the development of China' s railways over more than a century， as well as China' s development in general．
