On October 17,2016 the Shenzhou-11 manned spaceship was sent into space from the Jiuquan Satellite Launch Centre in Gansu. Two days later the spaceship successfully connected with the space laboratory Tiangong-2. It meant China got closer to its plan of building a space station in 2020.

    The spaceship took two Chinese astronauts to space this time. Jing Haipeng was an experienced astronaut who flew on Shenzhou-7 in 2008 and Shenzhou-9 in 2012. But it was Chen Dong's first space flight.

    Jing and Chen were given a 30-day task on Tiangong-2. They tested new technology and did experiments to prepare for future space station tasks. The astronauts themselves were also the subject(对象) of those experiments. The life support devices(设备) they used and how they lived inside the space laboratory were studied. No Chinese astronaut had stayed in space for that long before.

    A month-long space task was not easy, so Chinese scientists and engineers had come up with lots of new technologies to allow astronauts to stay more safely and more comfortably in space.

One of the new technologies tested during this task was a device called "space hospital". The space hospital was two little silver boxes tied around the two astronauts' legs. Through the "space hospital", scientists and doctors on the Earth could watch the astronauts' heart rate and temperature. When the astronauts felt tired, the "space hospital" could even massage(为……按摩) them.

    After this task, China is expected to send an unmanned cargo spaceship(无人货运飞船) in mid-April next year. It will dock with Tiangong-2 and take new fuel to the space laboratory.

    As the first report of the accident came in, Burton was sitting in his office on tile top floor of the building, Immediately, realizing the seriousness of the whole incident, he moved to a ground floor room with a small waiting-room to look into the matter himself, leaving his second in-command to take over all other cases.

    He interviewed the first witness almost at once, making sure that every thing was done that could be done to put him at his ease. However, the witness was obviously nervous and Burton took great pains to go over what he said thoroughly, choosing and checking each word carefully and taking the man's statement down himself. The witness had called the police, and he'd waited until the ambulances began to arrive then. When the first police car arrived on the scene, he'd been asked to report to the station which was what he had done.

    Burton explained that regrettably it would be necessary for him to go to court because of the serious nature of the disaster. More he could not say at present. He'd be grateful if the man could keep in touch with the police.

    When he had gone, Burton put his head in his hands and considered before asking for the next witness. The man couldn't be regarded as a hundred percent witness because he had been behind a wall when the explosion occurred. But in spite of his nerves, Burton had the impression that he was reliable, not afraid of incriminating himself to it and a fairly accurate observer.

    Well, there would be other accounts and no doubt all these would be slotted into place like a jigsaw and the whole picture would become clear. He raised his bead and pressed the buzzer on his desk.

    "Next witness, please." he said.

    Some people have a very poor sense of direction. Unlucky, I am one of them. I have visited a place many times but I may still get lost there the next time.

    When I was a little girl, I never dared ask strangers the way. And so I used to walk round in circle and hope that by chance I would get to the place I was going to.

    Now, I am no longer too shy to ask people for directions, but I often receive helpless or even wrong information. So I try to avoid(避免) giving people wrong directions. If anyone asks me the way somewhere, I would say, "Sorry, I am a stranger here."

    Once on my way to work I was stopped by a man. He asked me if I could tell him the way to the Friendship Building. I gave him my usual reply. But just as I walked on only a few steps, I realized that he had asked the way to my office building. However, I had no time to turn back and look for him. I was rushing to meet with someone at my office and I didn't want to keep him waiting.

    When I just got to my office, the secretary showed in the man who had asked me for directions. Imagine how embarrassed I was and how surprised he was when we saw each other at the first sight！

Leonardo da Vinci was a famous artist who was born in Italy. He was also a great inventor. Many of his inventions have become important in modern life. Although Leonardo hated war. he invented many different machines used for war. His most special invention was the machine gun, which was produced and used in war. Besides, Leonardo spent days thinking about how to save time. He developed ideas for something like cutting machines.

Leonardo was a strange man. He never ate meat. That was very unusual in those times. He never published(发表) discoveries about science. He usually used mirror writing, which looks like usual writing in a mirror, starting from the right side of the page and moving to the left side。

Only a few of his paintings are left today. Many paintings were not finished because he thought they were not perfect.

Leonardo was talented and creative. He was regarded as one of the most intelligent men in the world.

Every summer, drowning(溺水) accidents happen among students from time to time. The best way to {#blank#}1{#/blank#} (避免) drowning is to learn to swim. Swimming is both a {#blank#}2{#/blank#}(有用的) life skill and a great sport. Like any physical activity, swimming carries risks. So it's important to make sure your {#blank#}3{#/blank#}(安全). Here are some things you should know.

Don't swim {#blank#}4{#/blank#} (单独). You may fall, get hit or have other unexpected accidents. So always have someone with you. They can help you or call for help for you if {#blank#}5{#/blank#}(任何事) happens.

Swim only when you feel {#blank#}6{#/blank#} (舒适的). For example, don't swim if you have an open wound. If you develop pain while swimming, stop and rest.

Follow the pool rules and signs. They are there to {#blank#}7{#/blank#}(保护) you. So look for and read the pool safety information {#blank#}8{#/blank#}(仔细地) before getting into the water. And don't jump into any water {#blank#}9{#/blank#}(除非) you know how deep it is.

Be patient. It takes time to improve your swimming {#blank#}10{#/blank#} (技能).Maybe in the beginning you can only make it halfway across the pool before you need to take a break, and that' s okay. As you practice more, you' ll be able to swim a little longer each time.
