What will life in the future be like? Will it be much better than it is now? And what will we be able to do in 10, 20 or 30 years' time?

    Genetic engineering (基因工程)may help us make the perfect human. Babies may grow up to play basketball like Yao Ming or look like Cecilia Cheung. Also, we may be able to bring the dead back to life. Maybe people will be able to meet and talk with their dead family members.

    Over the next 20 to 50 years, it will become harder to tell the difference between humans and machines. Perhaps we will be able to make copies of ourselves, so we will appear to be alive long after we are dead. People may be able to find ways of putting the life of a person into a new body.

    Nanobots(纳米机器人)will be important. We will use them when we are sick. For example, when we have a stomachache, we will swallow (吞下) a nanobot and it will travel through our stomach, taking a video of what's happening there. The video will help the doctor cure us.

    In the future, computers may have their feelings. They may be able to think better than us. We may be more and more interested in computers and the internet, spending all our time in front of computers. Perhaps we will forget our real needs. Perhaps we will become super couch potatoes weighing 250 kg!

    Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit into the hand?

Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China's Huawei both showed foldable phones, The Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the "foldable future", The Verge noted.

    The technology could change our lives in unusual ways. These devices, due to their foldable screens, give us the larger screens we want. At the same time, they still fit easily into the pocket. As USA Today noted, they're "the combination of a small tablet and smartphone, all in a single device".

    The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modern cities, they will help us to make full use of available space.

    In a keynote speech, Samsung's senior vice president of mobile product marketing, Justin Denison, called the foldable screen "the foundation for the smartphone of tomorrow". "It's a piece of white paper for us to paint something beautiful on together," he said.

    So is there nothing to stand in the way of the foldable future?

According to technology news website Android Authority, the necessary displays* were difficult to produce. At present, these foldable devices cost too much. For example, the price of Huawei Mate X is 17,500 RMB. That's a price that few people will be able to afford.

    But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming.

    Patrick Moorhead, an industry expert told The Verge, "Few are debating if foldable mobile displays are the future of smartphones; the only question is when and by whom."

Each of us, rich or poor, should at least have one or two good friends. Your friends will listen to you when you speak, will take care of you when you are sick, and will be together with you in your journey through life. {#blank#}1{#/blank#} Here are some tips.

Keep in touch with people.

{#blank#}2{#/blank#} Get out of the house and do things that will put you in touch with people. Look people in the eye when you are talking to them. In that way, people will find it easier to talk to you. {#blank#}3{#/blank#} Because they may think that you are not interested in them.

Be a good listener.

Let people talk about themselves before talking about "me, me, me". {#blank#}4{#/blank#}

Make friends with people you really like.

Try to make friends with the kind of people you really like and respect, not just with those who are easy to meet.

Help and believe in each other.

Give your friend a hand when he or she is in trouble. {#blank#}5{#/blank#} Believe in each other. This is the most important thing in a friendship. Even the best friends may have a quarrel (争吵) sometimes. If this happens, don't let your quarrel last too long. Try to make up with (和好) your friends soon.

Do you think stones can move by themselves? Some stones can move in Death Valley（死谷）, the US. Death Valley is famous for this. Many of the stones are small. but a few of them are very big. The biggest stone weighs about 350 kg. 

The stones only move at night. Nobody has ever seen them moving, but now scientists know why the stones can move. The answer is the wind. When the wind comes from the west. the stones move to the cast. When the wind is from the south, they always move to the north. But how can the wind move a very heavy stone? 

Death Valley is one of the hottest places in the world, but it can be very cold at night. Sometimes. there are even storms at night. Rain falls, and the wind is strong and cold. The water on the ground turns into ice easily. Then the strong wind can move the stones along the flat ground. In the morning, the sun comes up and dries the ground. So people can find them move from one place to another in the daytime.
