In 1883, an engineer named John Roebling got an idea to build a bridge between New York and Long Island. However, bridge-building experts around the world thought that it was impossible. It had never been done before.

    After much discussion, he made his son Washington, a great engineer, believe that the bridge could be built.

    The project started well, but a few months later, an accident took the life of John Roebling. Washington was badly hurt and he was not able to walk or talk. However, Washington never lost his heart. He still wanted to complete the bridge. But all he could do was to move one finger. So he decided to make the best use of it. By moving his finger, he slowly developed a way of communicating with his wife.

    He touched his wife's arm with his finger, “telling” her that he wanted her to call the engineers again. Then he used the same way to tell the engineers what to do. The project carried on again.

    For 13 years, Washington tapped out (敲出) his instructions with his finger on his wife's arm, until the bridge was finally completed. Today the Brooklyn Bridge stands as a monument(纪念碑) to one man's unbeatable spirit.

    It is also a monument to engineers and their teamwork, and to their faith in a man who was considered crazy by half the world.

    A beautiful and very successful actress was the star for a new musical show. Her home was in the country，but she didn't want to go back there every night，so she bought an expensive house in the center of the city，got some beautiful furniture and got a man to paint the rooms in new colour.

    It was very difficult to get tickets for her show in the evening，because everyone wanted to see it. So she decided to give the painter two of the best seats. She hoped that this would make him work better for her. He took the tickets without saying anything, and she heard no more about them until the end of month，when she got the painter's bill. At the bottom of it were these words "Four hours from 5:00 pm to 9:00 pm watching Miss Hall sing and dance：3 pounds," with this note:"Before5：00 pm I get 10 shillings（先令）an hour and after 5:00pm 15 shillings."

In the past,space tourism sounded like a dream,but now it is becoming a reality(现实).

On September 15,2022,an {#blank#}1{#/blank#}(America)company sent four people into space.The four spent three days in space{#blank#}2{#/blank#}(do)almost everything they could do on Earth.They{#blank#}3{#/blank#} (fly)farther out than the International Space Station.

 Do you know Chatbots(聊天机器人) and other AI programs(人工智能项目)? Do {#blank#}1{#/blank#} ( student) need them at school? Do teachers need them at school, too? People look at it in different ways.

 Some people think Chatbots are useful to help students {#blank#}2{#/blank#} their study. They can give answers to {#blank#}3{#/blank#}( them) questions. They can guide (引导) students with questions. Chatbots can work seven days a week and twenty-four {#blank#}4{#/blank#} ( hour) a day. They can work with teachers, too. They can help teachers do lesson plans.

 However, Chatbots {#blank#}5{#/blank#}( be) not always useful. Students need {#blank#}6{#/blank#} ( learn) things about computer first. They may use computers later, {#blank#}7{#/blank#} now they learn penmanship (书法) and spelling at school. Some teachers do not use AI programs {#blank#}8{#/blank#}( good), so they can't get much help from them for their teaching and students. AI programs do not have human connection(人类连接). Students need that in their school life. A Chatbot only {#blank#}9{#/blank#} ( give) students answers. {#blank#}10{#/blank#} teacher knows how to help students get answers.
