How will our continuously growing population affect our way of life, our environment, even our planet? No matter how you look at it, we will face {#blank#}1{#/blank#}extremely serious problem. By the middle of the 21^st century, we {#blank#}2{#/blank#}(use) up all the oil that drives our cars if at the rate we're going. Even if scientists develop some new {#blank#}3{#/blank#}(way)of feeding the human race, the crowded conditions on the earth will make {#blank#}4{#/blank#}necessary for us to look for open space somewhere else. But none of the planets in our solar system are able  {#blank#}5{#/blank#}(support) life at present. One possible solution {#blank#}6{#/blank#}the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan. His idea is {#blank#}7{#/blank#}before the earth's resources are almost exhausted, it will be  {#blank#}8{#/blank#}(total)possible to change the atmosphere of Venus（金星）and so create a new world almost as large as earth itself.

    However, {#blank#}9{#/blank#} his idea is turned into reality, humans have a long way to go. On the one hand, Venus is much {#blank#}10{#/blank#}(hot)than the earth; on the other hand, there is only a tiny amount of water there.

    Traditional Chinese culture is{#blank#}1{#/blank#}(begin) to capture the attention of the world,this is also true even if popular culture{#blank#}2{#/blank#}has traditionally been considered Western begins to spread throughout China.

    China Kung Fu,especially,has had a great impact{#blank#}3{#/blank#}millions of people in the world{#blank#}4{#/blank#}it has been so fascinating in the eyes of westerners.Apart from that,they may come to China and learn about other aspects of this culture,such as traditional operas like the Beijing and Sichuan ones.Asian nations have long known about the{#blank#}5{#/blank#} (great) of ancient Chinese culture.Their own cultures are a mix of native ones and those Chinese characteristics.

    Actually,Korea and Japan long ago{#blank#}6{#/blank#}(adopt) ideas such as Confucianism as something that continues today even as it is challenged by Pop Culture.This strength comes from the ideas{#blank#}7{#/blank#}(give) in the Four Books（四书）of Confucianism (The Great Learning,The Doctrine of the Mean,The Analects of Confucius,and The Book of Mencius). These books built upon the ideas of{#blank#}8{#/blank#}even more ancient period codified in the Five Classics（五经）.From them, the West learns such things as Fengshui and other concepts that are{#blank#}9{#/blank#}(unique) Chinese.

    In recent years,China has taken steps to further this spread of culture by{#blank#}10{#/blank#}(establish) Chinese Cultural Centers in foreign counties,the United States and Europe,in particular.

    Since a university education in the United States {#blank#}1{#/blank#}(be)very expensive, most students work in addition to studying. Students {#blank#}2{#/blank#}(usual)work part-time, but some students take full-time jobs.

    A typical job for a students would be working {#blank#}3{#/blank#}a waiter or waitress. Other typical off-campus jobs would include being a clerk in a store or delivering pizza. Sometimes students also find jobs on campus such as cleaning, working in a cafeteria or library or answering {#blank#}4{#/blank#}(telephone). Most student jobs are entry-level and low paying, but have flexible schedule{#blank#}5{#/blank#}(allow) students to attend classes.

    Sometimes students also hold more responsible positions such as managers, or if they are lucky, positions in their area of study,{#blank#}6{#/blank#}they hope will help them find employment after they graduate.

    {#blank#}7{#/blank#}double responsibilities of working and studying result in a very busy,{#blank#}8{#/blank#} (stress)life for some students.{#blank#}9{#/blank#}, it is the only way for many people to finance their college educations. Some Americans believe that the work experience is good for the students {#blank#}10{#/blank#}(they)since it gives them a taste of “the real world” outside the school.

    Pollution takes away all the beauty of the beaches of Hawaii. I hate to go to the beaches on {#blank#}1{#/blank#}(sun) weekends and see rubbish bags{#blank#}2{#/blank#}(lie) on the sand, cigarette butts(烟头）{#blank#}3{#/blank#}(bury) in the sand, and soda cans floating in the ocean.

    One thing that really annoys me is that I see tourists who visit Hawaii leave their rubbish on the beaches. I was always taught after drinking soda to throw the can into the place {#blank#}4{#/blank#}it should stay at --the trash can. Another thing that annoys me is that some people walk right by rubbish {#blank#}5{#/blank#}pretend that it's not there.

    The dogs or the fish are not to blame for it. It's our fault and we must blame {#blank#}6{#/blank#}(we).Everyone has to do his or her part{#blank#}7{#/blank#} (solve) this problem. It can't be difficult to do the job. There are a lot of things that we can do. First of all, we can help pick {#blank#}8{#/blank#}rubbish along the beaches. We could also form organizations that help clean up our beaches, More{#blank#}9{#/blank#}(important),we need to start now before the beaches{#blank#}10{#/blank#}(damage) beyond repair.

    Friendship is very {#blank#}1{#/blank#}(importance). Everyone{#blank#}2{#/blank#} (need) friendship. In all our lives we can't live without friendship just as we can't live{#blank#}3{#/blank#} water. Friendship{#blank#}4{#/blank#} (make) us get on well with one another to go ahead under different {#blank#}5{#/blank#}(kind) of difficulties in front of us. But {#blank#}6{#/blank#} (really) friendship is not easy to come by. True friendship must be sincere and be based on{#blank#}7{#/blank#} (understand) each other but not on benefits of each other. A good friend can always be a good teacher to {#blank#}8{#/blank#} (we). By his advice we are persuaded {#blank#}9{#/blank#} (go) the right way. Therefore,{#blank#}10{#/blank#} more great friends we have, the better we can improve ourselves.

    While bottled water is convenient, it is also really bad for the environment. Not only does it create rubbish, but it also uses more resources because it {#blank#}1{#/blank#} (ship) to the shore. To be more eco-friendly, make it a habit {#blank#}2{#/blank#} (carry) a reusable water bottle with you everywhere so that you can drink water on the go. Plastic bottles are usually the {#blank#}3{#/blank#} (light) and most convenient. You can also find glass water bottles that are a great choice if don't like using plastic.
