Benjamin Banneker was born a few months before another great American—George Washington. Benjamin was black, but he was not a slave (奴隶). He and his mother and his grandmother were free. Benjamin's grandmother came from England. In America she got a job and worked for many years to pay for her boat trip across the ocean. After working many years, she saved enough money to buy a farm. Benjamin lived with her for a while. She taught him to read, write and do arithmetic (算术).

    Benjamin's neighbours knew that he was clever. They were not surprised when he built a large wooden clock. He made each piece after studying a small pocket watch. The clock made him famous, for it was one of the first clocks built in America. People from other places began to send hard problems of all kinds to Benjamin to settle.

    Thomas Jefferson heard of Benjamin Banneker's ability to settle hard problems. He asked Banneker to help build the city that was to be the capital of the United States—Washington, D.C. Banneker worked hard on the plans for the city. He marked where the streets and buildings—the Capitol (美国国会大厦), the White House, and many other places should be built.

    Later, L' Enfant, the Frenchman who had designed the new city, had a quarrel, and went back to France in anger. He took all of the plans away. The workmen couldn't build without any plans to follow.

    For a while it seemed that the plans for the capital might have to be changed, but Benjamin Banneker remembered the plans he had helped draw. He drew each again as he had built each piece of his clock.

    If it weren't for Benjamin Banneker, Washington,

    D.C might look very different from the way it does today.

What are the advantages and disadvantages of fast food? Many people do not have time to make{#blank#}1{#/blank#}(美味的) home-cooked food. Because of our non-stop modem lifestyle, fast food is popular almost everywhere. In most 

{#blank#}2{#/blank#}(城市), it is not difficult to find hamburgers, pizza, or fried chicken.

E{#blank#}3{#/blank#}fast food can help working people and students to get back to work as quickly as possible. Besides, many love the look, smell and {#blank#}4{#/blank#}(味道) of it. It is often cheaper than other kinds of restaurant food, so the {#blank#}5{#/blank#}(大的) advantage is the price.

On the other hand, many people feel that fast food is unhealthy because it has a lot of unhealthy ingredients. In f{#blank#}6{#/blank#}, some even think that it is addictive(上瘾的) because of these ingredients, and a{#blank#}7{#/blank#}because fast food companies advertise so much. They believe fast food will make people even fatter.

In a word, there are b{#blank#}8{#/blank#}advantages and disadvantages of fast food. As far as I'm concerned, I I{#blank#}9{#/blank#}(更喜欢) the saying that it can be a good thing, as long as people do not have it too often, have plenty of fruit and {#blank#}10{#/blank#}(蔬菜), and also do plenty of exercise to keep in shape.

Last year, some locals in Shenzhen suggested cancelling the city's ban（禁令）on fireworks. However, the local government said the city was not ready to allow fireworks.

The government said it was mostly because of the growing power of modern fireworks. Nowadays, in order to improve light effects, firework makers would put more gunpowder in their products. Sometimes, some of these fireworks may go off like small bombs（炸弹）, causing damage and hurting people.

During the last forty years, Shenzhen has developed into a huge city, and most of its population lives in urban（城市的）areas. Now, nearly 20 million people live in an area of just 2,000 square kilometers. In addition, there are at least 1,500 urban villages and 1,000 high-rise buildings.

Other major cities, like Beijing and Shanghai, allow people to set off fireworks at special areas during the Spring Festival this year. Shenzhen, however, has difficulty doing that because there is hardly enough public space, especially in urban villages. There, you will see plenty of "handshake" buildings. These buildings are usually several inches—the distance of a few handshakes—away from each other. If people set off fireworks through their windows, it may cause fire. Therefore, the locals and the government are working together to keep them clean and well-organized. As a result, people can enjoy a happy and safe new year.

Shenzhen made a rule in 2013 to ban fireworks. Once the rule was made, it caught a lot of attention from the public. After much explanation, people started to take it. No major fire has been caused by fireworks since then.

I'm Tony. I'm an English boy, but now I'm in Wuhan. My parents come to Wuhan for work. So I come here with them. 

I like Chinese very much. It's my favorite subject. My Chinese classmates can speak Chinese very well. I always ask them for help. And I help them with their English. In my free time, I like watching TV and practicing (练习) my Chinese from TV. After eight months, I can speak Chinese very well. 

My science is good, too. I think it's very interesting and useful. But my math is not very good. I don't know much about math. Math lessons are not easy for me. I want to thank my Chinese classmates. They always help me with it. 

On Saturday and Sunday I like to play with my Chinese classmates. I know many things about China from them. And I make many Chinese friends. We always have a good time!

 Many students have already had clear ideas about what jobs they would like to have in the future. We believe boys' choices are different from girls'. To find out how different their choices are, we made a survey in Green High School. The following diagram shows the results of the survey.
