1 . Artificial intelligence (人工智能) is set to benefit mankind in many ways. It will make everyday tasks easier and bring efficiency to many industries. It might be one of man's greatest inventions.
And yet, like any other technology, AI will also bring risks. In February 2018, a group of AI experts got together to discuss the possible disadvantages of AI. What they found was that "Every AI developed by the good guys is also helpful for the bad guys, too." according to Quartz.
Their biggest worry was that the bad guys could use AI for bad things. One of the areas they looked at was the use of AI to create websites that could be used to steal people's personal information. Another possibility is that AI programs could be used to hack software and break into computer secure systems (安全系统).
There are some other worries as well. It is possible that AI could be used to create fake imagines and videos. Baidu, in fact, has developed a program called Deep Voice that can "clone (克隆)" anyone's voice by studying a 3.7-second audio sample (音频样本).
Many leading people have expressed worries about AI. People like Bill Gates and Elon Musk have called for the industry to be more strictly controlled, as there are few laws right now on the use of AI.
However, this is set to change. In March 2018, the European Union plans to set up a group that will discuss the moral and ethical (伦理道德的) dangers of AI, which will help to keep it safe for mankind.

2 . Something very special happened to Tamara. She never knew she had a twin sister until she started university!
Tamara was born in Mexico. Her parents could not look after her so she went to live with a family in Manhattan, New York, USA.
When Tamara was twenty years old, she started university in Long Island. She enjoyed her university life. But one day she was walking home from class, and a student smiled at her. “Hello, Adriana!” said the student. “I’m not Adriana,” said Tamara.
This happened to Tamara again and again. Tamara didn’t know why people kept calling her Adriana. One day, when a woman called her Adriana, Tamara asked, “Why do you keep calling me Adriana?”

3 . During the novel coronavirus outbreak, hospitals all over China have used smart technology to care for patients and make work easier for doctors. The outbreak will help smart healthcare develop faster in China, according to Xinhua.
Robots lend a hand
Robots are being used to fight the virus. For example, medical workers at the Third People’s Hospital of Shenzhen are using robots to do routine (常规的) medical tasks.
Developed by Chinese AI company UB Tech, these robots can offer medical advice, deliver (递送）medicine and disinfect (消毒) wards (病房) and other areas. They can also check temperatures, according to China Daily.
Liu Yue, head of the hospital’s fever outpatient services (发热门诊), said the robots have made work much easier. “It greatly reduces our burden (负担), and it can also prevent us from missing infected patients,” Liu said.
Remote (远程的) healthcare services
It can be dangerous for medical workers and patients to come into contact (接触) with each other. But with remote medical services, doctors at different hospitals can share photos and videos to come up with the best treatment. China’s three biggest telecom companies are providing hospitals across the country with 5G support. This allows them to transfer(传送) large amounts of data (数据) quickly.
For example, on Feb 27, doctors in the cities of Beijing, Shanghai and Guangzhou used 5G technology to treat a severely (严重地) ill 67-year-old patient in Wuhan, according to China Daily. By diagnosing (诊断) patients remotely, doctors can protect both themselves and their patients.
AI makes work more efficient (高效的)
Ask Bob is an AI-powered consultation (咨询) platform. Developed by Ping An Smart Healthcare, it can provide users with information about the virus, help people do medical self-checks, check their mental (心理的) health and choose the right face masks, according to China Daily.
Ping An Smart Healthcare has also developed AI software that can read CT images and provide accurate (准确的) analyses (分析) to doctors. This can speed up the diagnostic process and allow doctors to give faster treatment.

6 . An organism’s environment is all the living and nonliving things that surround and influence the organism(生物体). You are living with many things that make your environment suitable for you to live in. Would that be true if you lived in a swamp(沼泽)?
Environments include biotic parts and abiotic parts. Biotic parts are the living things in an environment: plants, animal, and other organisms. Abiotic parts are the nonliving things. Abiotic parts of an environment include climate, water, earth, light, air and nutrients. The abiotic parts of an environment have an important role. Temperature and amount of water influence which plants and animals can live in a place. An ibis(朱鹮) gets used to living in a warm, wet swamp and cannot live in a hot, dry desert.
An ecosystem is all the organisms living in a place together with their environment. An ecosystem can be huge, such as a large forest or desert. Or it can be small, such as a small pool or a single bush. Each ecosystem has its own collection of living and nonliving things.
A swamp ecosystem is made up of both living and nonliving things. The climate, plenty of water, air, muddy soils are all abiotic parts that make swamps different from other environments. Birds, black bears, trees, bushes, and mosquitoes are all biotic parts of a swamp environment.
1. Biotic parts include many things in an environment except _________.| A．snakes | B．strawberry | C．wheat | D．sand |
| A．the organisms | B．the abiotic parts | C．the ecosystem | D．the swamp |

The label(标签), Made in China, is one that is becoming increasing common in shopping centers all over the world.
In the United States, shoppers at Wal-Mart, the nation’s largest retailer(零售商), have a wide selection of products mostly produced in China. The large amount of Chinese imports have created a large selection of goods in other countries as people begin to buy more and more products made in China. These goods are even widely available in other Asian nations, where Chinese-made goods are quite popular. Chinese brand names are also becoming more well-known outside China.
When Chinese Americans visit family and friends in their homeland, gifts from the U.S. are a must. But TVs and fashionable clothes aren't rare any more, and anything 'Made in China' shouldn’t be considered in any case.
"When I decide to visit my family members in China, I will have a big headache. What should I buy for them? They may not all speak English, but everyone in China knows those three words," a Chinese American said. "When they see the label 'Made in China,' they will think, 'Why do you send me this?' "
The development of China has surprised the world with its growth. As a result, the other countries are beginning to try to reduce Chinese goods with the use of taxes(税)and import restrictions. However, the development on the Chinese economy still affects the world in many ways.

8 . We spoke to three students from around the world about different national holidays. There are different customs (习俗) for each festival.
Tan Xiaodong. 15. Hong Kong, China
“It’ll be Chinese New Year soon. Before it we’ll clean the house and decorate(装饰) it for good luck. Every shop is going to close for a few days and we’ll go out a lot to celebrate in the streets. We might go and see the lion and dragon dances in the city center. I love this festival. ”
Wendy, 16, Sydney, Australia
“Australia Day is on 26th January and it’s an important holiday here. We always have a Monday off, so we celebrate for three days.

Amy, 14, New York, the USA
“The first Thanksgiving Day was hundreds years ago when Europeans who came to America thanked God for his help. It’s still a very important day for families to be together.

For some of us， though making friends is not difficult， feeling shy， we may not want to make the first move. It is also difficult at times to keep the friends we already have.
There are many books about friendship， but Dale Carnegie’s How to Win Friends and Influence (影响) People， written in 1936， is the most famous. This “how to” book about getting along with other people became a best-seller. It was later put into 28 languages.
Dale Carnegie’s advice (劝告) seems to be simple， but can his advice help you? Do you need to change the way you act? Here is the list of advice from his book.
1. Be friendly and polite.
Always greet with a smile. Begin with “excuse me” or “would you please”， when you want to ask somebody. Remember to say “thank you” and try to be as helpful as you can.
2. Go out of your way to be nice.
Find some time to do special things for other people. Making some soup for a sick neighbour may seem like a little thing to you， but it will make your neighbour feel a lot better.[来源：Z|xx|k.Com]
3. Remember names.
They say that the sweetest music to a person’s ears is the sound of his or her own name.
4. Be open-minded.
Try to understand other people’s ways and ideas and learn something from them.
5. Listen patiently.
When someone is talking to you， look at him or her， listen carefully and say something when necessary.

For example, if you say bad things about a person, the person might protest and say “Do not badmouth me.”
Sometimes, people say something to a friend or family member that they later regret because it hurts that person’s feelings. Or they tell the person something they were not supposed to tell.The speaker might say: “I really put my foot in my mouth this time.” If this should happen, the speaker might feel “down in the mouth.” In other words, he might feel sad for saying the wrong thing.
Another situation（情况）is when someone falsely claims （宣布）another person said something. The other person might protest: “I did not say that. Do not put words in my mouth.”
Information is often spread through “word of mouth.” This is general communication between people, like friends talking to each other. “How did you hear about that new movie?” someone might ask. “Oh, by word of mouth.” A more official way of getting information is through a company or government mouthpiece（发言人）. This is an official spokesperson. Government-run media could also be called a mouthpiece.
