More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit(受益）from the enjoyable exercise without polluting the environment. You don't even have to ride all the way.

    Folding(折叠）bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can take a common bike with you when you fly, too. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travelers.

    May 12th, 2018 is the 10^th anniversary of Wenchuan Earthquake. Many of us may have remembered what happened on May 12th, 2008. The devastating 7.9 magnitude Sichuan earthquake which killed about 90, 000 people in western China. It has been concerned(担忧) widely about what we can do when we encounter(遭遇) certain accidents. Therefore, how to deal with accidents in our daily life?

    Earthquake is the first thing that I am going to talk about. Firstly, you need to rush to open space quickly if you are in a lower floor. Meanwhile, you should avoid trees or wires around you. On the contrary (相反), you need to stay in a corner which seems firm if you are in a higher building. {#blank#}1{#/blank#}You should keep your body safe and wait for others to help you.

    When it comes to fire, you need to distinguish the root of the fire and find out security exits. {#blank#}2{#/blank#}Then you should crawl (爬行)on the floor. Do not use elevators or any electronic equipments.

    Another accident is drowning. Every summer, about 5, 000 kids die because of swimming alone in the river or the lake. Experts say that we have the more possibilities of drowning if we struggle as possible as we can. So what we should do is: “{#blank#}3{#/blank#}” The summer holiday is coming. My dear friend, take care of yourself.

    In a word, all kinds of accidents will happen in our daily life. {#blank#}4{#/blank#}We should believe that the rate of danger can be minimized(机会少)and we can not only get a chance to save ourselves but also help more others if we learn about how to deal with them in the first place.

A. The most necessary thing is to keep calm and find the exact way

B. Do not be a jumper!

C. To take a deep breath, lie on the water and wait for others to save us.

    It was a beautiful spring（春天） morning. There wasn't a cloud in the sky, and the sun was warm but not too hot. So Mr. Andrews was surprised when he saw an old man at the bus-stop with a big umbrella in his hand.

    Mr. Andrews said to him, “Do you think it's going to rain today?”

    “No,” said the old man, “I don't think so.”

    “Then are you carrying the umbrella because the sun is too hot?”

    “No, the sun is not very hot in spring.”

    Mr. Andrews looked at the big umbrella again, and the man said, “I am an old man, and my legs are not very good, so I really need a walking-stick (拐杖). But people will say, 'Look at that poor old man', and I don't like that. When I carry an umbrella in fine weather, people only say, 'Look at that stupid（愚蠢的）man'.”

    The Internet is shaping our lives. We already have online shopping services and mobile payment. However, this is just a start. The world's leading tech companies are planning to build smarter online communities. {#blank#}1{#/blank#} It was held in Wuzhen, Zhejiang last year. The development of artificial intelligence(AI,人工智能) was a hot topic at the conference(会议). If a machine can learn and solve problems as humans do, it can be called AI.

    The company Alibaba uses AI technology in its unmanned supermarket in Wuzhen. There is no salesperson in the supermarket, just a tablet on a desk that says "please smile". {#blank#}2{#/blank#} The bigger your smile is, the more discounts(折扣) you will get. Payment is done automatically(自动地) through your Alipay(支付宝)account. When you first enter the supermarket, the supermarket's AI recognizes your face and your account.

    There is also AI that can read lips. {#blank#}3{#/blank#} It recognizes your mouth, s movements and turns them into voices or text messages. This could be very useful when you are trying to talk to someone on your phone in a noisy place. Police could also use the technology to help them find criminal suspects by lip﹣reading recordings from video cameras.

    {#blank#}4{#/blank#} Microsoft's chatbot Xiaolce can not only provide useful information, but also chat with people like a real friend. Xiaolce has a WeChat account. After following the account, users can start talking with her. {#blank#}5{#/blank#} She keeps improving herself by talking with users.

    These technologies are being put into wider use. We may see a smarter world and better lives in the near future.

A. She knows when to comfort you or tell jokes.

B. They discussed this at the World Internet Conference.

C. Sougou brought its lip﹣reading system to the conference.

D. If you smile, it will give you a special discount for your goods.

E. Another type of AI focuses on understanding human emotions.
