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.

    When I called up my mother in the countryside on the phone, she told me snakes came to her home now and then, and {#blank#}1{#/blank#} they seemed to have made their home there. I got the chance to distinguish {#blank#}2{#/blank#} by inventing something {#blank#}3{#/blank#} (mercy) to catch the snakes.

    No products can help me catch snakes, so I set out {#blank#}4{#/blank#} (research) the habits of snakes to trap them. I decided on three approaches: firstly, removing their habitat; secondly, {#blank#}5{#/blank#}(attract) them into {#blank#}6{#/blank#} trap, and thirdly cooling them. I used the {#blank#}7{#/blank#} (freeze) bowl to make the snakes less active, {#blank#}8{#/blank#} then collected them. The next day I released them into the wild.

    I have filled {#blank#}9{#/blank#} the form and filed my patent {#blank#}10{#/blank#} (apply) with the Patent Office.

Recently I failed an exam. However, when I came out of my teacher's office, I told myself, "Smile! It's not so serious."

    I smiled a big smile and it {#blank#}1{#/blank#}(work) a little, really.

Everyone gets {#blank#}2{#/blank#}(disappoint) sometimes. I used to be always influenced by pressure and I was often in low spirits. But one day I meet {#blank#}3{#/blank#}a sentence in the Bible, "Do not be anxious about tomorrow, for tomorrow will be anxious for itself, let the day's own trouble be enough for the day." {#blank#}4{#/blank#} suddenly occurred to me that {#blank#}5{#/blank#}(worry) about a problem doesn't help. Why not just give a big smile and face up to the trouble？"

    Now every time I want to cry, I remind myself that {#blank#}6{#/blank#}(laugh) is better than tears and anger. I {#blank#}7{#/blank#}(deep) believe that there's something magical about a smile. A smile helps me recover confidence and gives me {#blank#}8{#/blank#}courage to move on.

    Remember, whenever you're faced with a setback, {#blank#}9{#/blank#} difficulty you come across, all it takes is determination and you can feel happy again. Smile at life, {#blank#}10{#/blank#} it will shine on you.

    A television series is fast gaining its word-of-mouth {#blank#}1{#/blank#} (popular) among not only Chinese households but also some foreigners. The drama, {#blank#}2{#/blank#} (call) In the Name of the People, offers viewers, {#blank#}3{#/blank#} (particular) foreigners, an opportunity to better understand China's politics and culture and also the nations' iron-fist resolve in the fight {#blank#}4{#/blank#} corruption(腐败) among the country's officials. The drama is {#blank#}5{#/blank#} effort rarely seen in recent memory that carries the anti-corruption topic onto mainstream television. Before that, the discussion of this topic was widespread {#blank#}6{#/blank#} mostly remains private in Chinese society.

    “I was quite {#blank#}7{#/blank#} (impress) by the jaw-dropping scene {#blank#}8{#/blank#} the cash hidden on a giant wall was found in a low-level official's house. It is a bribe(行贿)he's accepted which is worth 230 million yuan (about 33 million U. S. dollars)”, said Eric Ivarsen from Norway, a master's student {#blank#}9{#/blank#} (major) in the public management and social development at the University of Chinese Academy of Science.

    “My subject has a very high requirement of knowledge about Chinese politics and culture. After watching the drama, I {#blank#}10{#/blank#} (well) understand China's political terms, for example, seats order according to official rankings, languages being used in a meeting, which is quite different from my country,” lvarsen added.

    Suddenly, wildlife is good for the tourist trade. And tourism—{#blank#}1{#/blank#} it takes only pictures and {#blank#}2{#/blank#} only footprints—is good for the national parks. If wildlife can be seen to be {#blank#}3{#/blank#} its way, then its {#blank#}4{#/blank#} of {#blank#}5{#/blank#} will be much greater.
