Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you. Companies like Google and Tesla have been designing and testing these cars, and the technology is there.

    So how? The cars have sensors（感应器）all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems（卫星导航系统）are used so the car knows how to get where you want to go. All you have to do is type in the address! Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.

    Sound like your idea of heaven（天堂）? Sitting back, looking out of the windows and even watching a film or reading a book while ‘driving' would be possible with this new technology. You wouldn't have to worry about remembering directions to where you're going. In addition, computers would also drive more safely than people — they would obey the rules and have quicker action times when in dangerous situations.

However, there are many drawbacks of driverless cars. Computers would have difficulties making ethical（道德的）decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly and potentially kill the car's passengers? Moreover, I personally find driving fun –I'd miss never driving a car myself. There would also be many other decisions to be made –should children, or drunk people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?

    I'm not certain I'd want a driverless car – but it's only a matter of time before they'll become more affordable and popular on our roads.

    How do you pay for your meals at a fast food restaurant? With change(零钱)? Nowadays we have We Chat wallet and Alipay.

    I use my tap-and-go card(感应式信用卡). I don't even need to enter my PIN number(SIM卡密码)or a signature(签名)to pay money. It's quicker and everybody in the queue(队)is happy.

    Contactless payments(非接触式支付)are more and more popular, but the safety (安全性)still needs improving(改善). And people shouldn't pay too much at a time-in the UK it's ￡30. If you use the card a few times, you will need your PIN number.

    Some things, such as your clothes, have been combined with electric technology(与电子技术联系起来). Kenneth Cukier, the writer of the book Big Data, says, "You can take any card and put it in a coat. When you make a payment, just wave your arm in front of the terminal(终端)." This is for people who don't want to take their card out of their pocket, or use their phone or watch.

    Good, isn't it?

    So spending money is becoming easier at the time. And people are buying more and more things. But making money still needs the hard work.

    Back to work then!

Dark tea has a long history of being carried on horseback to China's northwestern areas as well as abroad. But as the fashion for new﹣style tea swept China，dark tea found new fans in big cities，mainly thanks to the thousands of bubble tea（珍珠奶茶）

In Changsha，the capital of Hunan，tea shops mix dark tea with light cream and pecans and advertise its health﹣improving effects（胆固醇）. "I like bubble tea but I don't want to get fat，so I'm interested in the health﹣improving effects of dark tea，"said Peng Hongzhi，a 37﹣year﹣old Changsha resident. Peng notes dark tea is famous for its bitter（味苦的），which causes a challenge to developers of popular drinks. 

Sexy Tea is a popular tea brand also known as the Modern China Tea Shop. It said it began to develop dark tea﹣based drinks in 2019 to diversify（使多样化） its products of green，black and olong teas. The company chose dark tea with richer flavors and added cream to improve the taste. 

"Dark tea has a strong personality. Some people love it，but some hate it，"said Liu Qiaofang

Liu Yang，the founder of Chaermasi Chinese Dark Tea，is one of the young businessmen working on dak tea. "We want to introduce dark tea into the lives of young Chinese in a more fashionable manner，who has opened four shops that use dark tea to make bubble tea and fruit tea. 

As a newecomer to the new﹣style tea market，dark tea drinks have few successful examples to draw experience from，so Liu's team mixes the tea with fruit and dried orange peel to increase its health benefits. "Luckily，"he said，expecting a growing number of health﹣conscious（关注健康的）

Recently, many people think it's risky to use credit card numbers online. However, from time to time passwords and ID numbers on the Internet We think we are safe, but that may not be true! A new kind of attack is being used by dishonest people to steal IDs and credit card numbers from web surfers. This new kind of attack is called "phishing"

Phishing sounds the same as the word "fishing", and it means that a thief is trying to trick people into giving away valuable information, Like real fishermen, phishers use bait in the form of great online deals or services. For example, phishers might use false emails and websites to trick people into revealing (透露) credit card numbers, account usernames, and passwords. They imitate (模仿) well-known banks, online sellers, and credit card companies. Successful phisher s may make as many as 5%of the people believe and give away their personal in formation. 

    ★     Actually, tricking 5% of the online population is huge. Now more than 4. 6 billion people have access (进入权) to the Internet, and 75% of those Inter net users live in the wealthiest countries on Earth. It has been reported that phishers send more than 40 billion false messages each year. Even by tricking only 5%of the people, phishers can make a lot of money. 

Amy, 18, from California, received an e mail. A man told Amy that she could get a million dollars in her account as a reward if she sent a thousand dollars to him. Amy did as the man said at once. The "thief" used Amy's Social Security number to get credit cards in her name and transferred her money. 

How can people avoid being cheated online? Above all, they have to learn to recognize the e-mail that be sent by a phisher. Always be careful with any email with urgent requests for personal information. Phishers typically write upsetting or exciting, but false statements in their emails so that people will reply right away Never give out personal information to phishers. And if an offer sounds too good to be true, it is. 

I come from Lanxi, Zhejiang. I want to tell you a story. {#blank#}1{#/blank#} My father's name is Li Wenwen. He is a big fan of Lei Feng. And he likes collecting old newspapers, too. {#blank#}2{#/blank#} He then got the idea of collecting things about him. My father has many old things about Lei Feng. He not only collects those things but also listens to stories behind them.

{#blank#}3{#/blank#} She asks him to have some exhibitions(展览), so more people can learn from Lei Feng. Now, there is an exhibition room in my house. People can see a lot of old things about Lei Feng in it.

 My father wants people to inherit(继承) the spirit(精神) of Lei Feng. {#blank#}4{#/blank#} On Saturdays and Sundays, he often goes to visit a children's home or an old people's home. He always says, "{#blank#}5{#/blank#}" I think my father is great!
