Every individual is a member of a group called the community, and it is the duty of every citizen {#blank#}1{#/blank#} ask what he can do for his community. A good citizen {#blank#}2{#/blank#}(相信) that he should serve the community and not the community serve h{#blank#}3{#/blank#}. As students, there are many ways in {#blank#}4{#/blank#} you can serve the community. Above all, however, you have to acquire a certain amount of skill and experience b{#blank#}5{#/blank#} you can be of service to others. Your school has lots of{#blank#}6{#/blank#}(活动) which prepare you {#blank#}7{#/blank#} good citizenship. Many school societies train students to become good citizens who later p{#blank#}8{#/blank#} in volunteer work and serve the public in t{#blank#}9{#/blank#} of need. If you serve your community, you will grow {#blank#}10{#/blank#} to be a good citizen with a strong sense of responsibility.

    Some years ago,writing in my diary used to be{#blank#}1{#/blank#}usual activity. I would return from school and spend half an hour {#blank#}2{#/blank#}(record)the day's events, feelings, and {#blank#}3{#/blank#}(impress)in my little blue diary. I did not really need {#blank#}4{#/blank#}(express) my emotions by way of words, but I gained a certain satisfaction from {#blank#}5{#/blank#}(see) my experiences forever recorded on paper, After all, isn't accumulating(积累）memories a way of preserving the past?

    {#blank#}6{#/blank#} I was thirteen years old, I went on a long journey{#blank#}7{#/blank#} foot in a great valley{#blank#}8{#/blank#}(equip) with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt {#blank#}9{#/blank#}(pride) to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I {#blank#}10{#/blank#}(walk)out of my tent, diary in hand.

    Domestic robots such as the Roomba have already established themselves in the marketplace. Common household appliances such as toasters and microwaves {#blank#}1{#/blank#}(fit) with microprocessors, effectively making them robots, which are bound to do as ordered. The military has begun automating (自动化) many of its frontline systems. The future is wide open for more exploration of these{#blank#}2{#/blank#}(device).

    Automatic factories were some of the first to implement (实施，运用) robotics on the assembly line, performing tasks too dangerous or delicate for humans{#blank#}3{#/blank#}(accomplish). This has continued with whole factories{#blank#}4{#/blank#}(begin) to be automated. IBM has instituted a “lights off' factory in Texas that is {#blank#}5{#/blank#}(complete) automated. Recently Caterpillar{#blank#}6{#/blank#}(announce) plans to operate robotic heavy machinery by 2021, and has already begun transferring much of their crane operations to remote-controlled robots{#blank#}7{#/blank#}obey the orders from computer directions. The medical industry has taken advantage {#blank#}8{#/blank#}robotic surgery assistants for years, most notably the Da Vinci surgical (外科的) helper. With rising health care costs{#blank#}9{#/blank#} the increasing needs of an aging population, hospitals are planning vast expansion in the areas of {#blank#}10{#/blank#}(talent) robotics.

    My grandfather is a{#blank#}1{#/blank#} (retire) worker. On summer evenings, we often sat together outside the house {#blank#}2{#/blank#} (enjoy) the cool air. It was the time that he told me lots of his experiences before liberation.

    When my grandfather was fourteen years old, he worked in a coal mine. One day, when he and his two workmates were working in the tunnel, an{#blank#}3{#/blank#} (fortune) thing suddenly happened. A part of the tunnel fell down, and they were shut in it. They had no food {#blank#}4{#/blank#}(eat). When they were hungry, they only drank some water there. It was very cold in it. In order to keep warm, they hugged one another. In the darkness, they didn't know whether it was day{#blank#}5{#/blank#}night, they only felt they had stayed there for a very long time. They were too hungry to speak or move, and thought they{#blank#}6{#/blank#}(die). At last, the tunnel {#blank#}7{#/blank#}(dig) through. They were saved. They had been there for fourteen days! My grandfather said they weren't let out at once. If{#blank#}8{#/blank#}，they would have died. They were kept at the entrance to the tunnel {#blank#}9{#/blank#}it was very dim, and they were fed{#blank#}10{#/blank#}some thin porridge. After a day or two, they had recovered a bit, and they were helped out.

    Are you facing a situation that {#blank#}1{#/blank#}(be) impossible to fix?

    In 1969, the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It was unimaginable that it could ever be cleaned up. The river was so polluted that it {#blank#}2{#/blank#}(actual) caught fire and burned. Now, years later, this river is one of {#blank#}3{#/blank#} most outstanding examples of environmental cleanup.

    But the river wasn't changed in a few days {#blank#}4{#/blank#} even a few months. It took years of work {#blank#}5{#/blank#}(reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is {#blank#}6{#/blank#}(clean) than ever.

    Maybe you are facing an impossible situation. Maybe you have a habit {#blank#}7{#/blank#}is driving your family crazy. Possibly you drink too much or don't know how to control your credit card use. When you face such an impossible situation, don't you want a quick fix and something to change immediately?

    While there are {#blank#}8{#/blank#}(amaze) stories of instant transformation, for most of us the {#blank#}9{#/blank#}(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be {#blank#}10{#/blank#}(patience).

Body language is one of {#blank#}1{#/blank#} most powerful means of communication, often even more powerful than {#blank#}2{#/blank#}(speak) language. People around the world show all kinds of feelings, wishes and attitudes that they might never speak aloud. {#blank#}3{#/blank#} is possible to "read" others around us, even {#blank#}4{#/blank#}they do not want us {#blank#}5{#/blank#}(catch) their unspoken communication. Of course, body language can be misread, but many{#blank#}6{#/blank#}(gesture) and actions are universal. The most universal {#blank#}7{#/blank#}(face) expression is, of course, the smile—its function is to show happiness and put people {#blank#}8{#/blank#} ease. It does not always mean that we are {#blank#}9{#/blank#}(true) happy, however. Smiles around the world can be false, hiding other feelings like anger, fear or worry. There {#blank#}10{#/blank#}(be) unhappy smiles, such as when someone "loses face" and smiles to hide it. However, the general purpose of smiling is to show good feelings.
