When you go on a trip, it's easier to get sick because your body isn't used to the food, water, and air in a new environment. Here are some tips on keeping your travel experience as healthy as possible.

    Have safe foods and drinks.

    So what foods are safe to eat? Any boiled food, fresh fruit and vegetables are safe for you. Peel(剥) the fruit before eating. You should try to drink only bottled (瓶装的) water when traveling. If you need to use tap water (自来水), you should boil it first.

Take some medicines.

You should also put some medicines in your bags, because they may be hard to find in another country. It's a good idea to always carry your medical history with you. This helps doctors well, and you won't have to worry about forgetting important information.

    Basic Safety

    You'll need to reset your thinking when it comes to traffic safety. The rules of the road aren't the same as they are at home. In some countries, people drive on the left side of the road, and you'll need to be careful before you cross the street. Be sure there are no cars coming when you step into the street: If there are, they may not stop for you!

    One day, my wife and I went shopping. We took the car as we had a lot of things to buy, because my brother and his family were going to spend the weekend with us. We stopped the car in front of the shop. An hour later we came back to the car with a lot of things. Then the trouble(麻烦) started. We could not open the door.

    "Oh, dear," said my wife, "what are we going to do?"

    "Let's ask that policeman," I said.

    The policeman was very kind and glad to help us. Soon he got the door open. Just at that moment, an angry man came up and shouted. "What are you doing with my car?" We looked at the number of the car, and our faces turned very red.

    Many people were really surprised last Wednesday when money started falling from the sky. The accident happened on Green Street. A company clerk（职员） was crossing the busy street with a bag. In the bag, there was 50,000 dollars. She was going to put the money in the bank. Suddenly, a strong wind blew her skirt up. The clerk put her hands on her skirt right away. But she dropped the bag at the same time. The wind blew the money into the air and it fell all over the street. She rushed to pick up all the money she could find at once, and a lot of people came to help her as well. But she could only get back 44,500 dollars.

    When the clerk went back to the company, she felt really worried. She thought she had to pay off （偿清） the lost money. However, after she told her boss what had happened, to her surprise, the boss didn't ask her to pay back the money. Instead, he told her to wear trousers to work from then on.

    My mom hates to cook. She'd rather ride her motorcycle or practice rock climbing. She also spends a lot of time with me. Every morning Mom takes me to school by motorcycle. Occasionally I'll come home to find her scaling(攀爬)the side of the house.

As her daughter, I used to feel embarrassed that my mom was so different. But now________.

    It all started with a cooking project. Every student in Mrs. Maitland's home-economics class was supposed to create an original dish, then present it at school the following Tuesday morning. Mom and I spent hours in the kitchen. We tried jelly-filled hot dogs, baked ham with chocolate sauce, and hard-boiled eggs rolled in coconut. We eventually agreed on chocolate cakes with bright green pepper mint frosting. I was satisfied. It beat hot dogs, anyway.

    The big day came. Our parents appeared, bringing many tasty dishes. Finally, I saw Mom, empty handed! I met her at the door. "You forgot it, didn't you?"

    Mom's eyes opened wide. "I'm sor--" She couldn't finish her apology. A loud alarm cut her off. Mrs. Maitland yelled, "Fire! This is not a drill! Everyone out of the building!"

    We all headed for the stairs and gathered at the parking lot. Smoke started to curl out of one of the third-floor windows. Mom held my hand tightly. I forgot about my cake.

    Suddenly, we heard a scream. We looked up and found Danny Patterson was trapped in the burning building! Mom disappeared. She grabbed her climbing tools from her motorcycle and walked quickly toward the building.

    She scaled the huge pine tree next to the school. At the top, she started to throw her weight back and forth. The tree swung toward the window, and she hopped onto the ledge and into the building.

    Mom's ropes flew as she created a harness. She secured one end, and then lowered Danny safely to the ground. Everyone cheered!

    Who cares if my mom hates to cook?

    Some people seem to be born happy. Nothing seems to get them down. However, some people seem to have everything going well but they still do not seem to be happy. {#blank#}1{#/blank#}

    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.
