If the population of the Earth keeps on increasing at its present rate, there will eventually not be enough resources {#blank#}1{#/blank#} (leave) to support life on the planet. By the middle of the 26^th century, if present trends continue, we {#blank#}2{#/blank#}（use）up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on the earth will make{#blank#}3{#/blank#} necessary for us to look for open space somewhere else. But {#blank#}4{#/blank#} of the other planets in our solar system are capable of supporting life at present. One possible solution {#blank#}5{#/blank#} the problem, {#blank#}6{#/blank#}, has recently been suggested by an American scientist, Professor Carl Sagan. Sagan believes {#blank#}7{#/blank#} before the Earth's resources are {#blank#}8{#/blank#} (complete) exhausted it will be possible to change the atmosphere of Venus and therefore create a new world almost as large as the Earth {#blank#}9{#/blank#}.The difficulty is that Venus is much hotter than the Earth. {#blank#}10{#/blank#}, there is only a tiny amount of water there.

    Can you imagine yourself {#blank#}1{#/blank#} （work） on a project alone in office, and no one out there to support and assist you? Definitely not! We all love to be a part of a team and do things through teamwork. {#blank#}2{#/blank#}just makes life easier.

    Teamwork can {#blank#}3{#/blank#}( explain) as an activity or a set of inter-related activities done by more than one person {#blank#}4{#/blank#}(meet) a common goal. Teamwork is not only followed in the corporate world today, rather it is one of the {#blank#}5{#/blank#}(old) things known to man. Mankind has worked in teams and groups since the primitive days of civilization. Hunting in groups {#blank#}6{#/blank#}(be) a suitable example of teamwork during those days. It is only in recent times {#blank#}7{#/blank#}it has been developed as a “concept” in the management jargon（术语）.

    Working as a team can benefit you as an individual, as a team, as well as an {#blank#}8{#/blank#}(organize). For some people, initially, it might be a bit difficult to adjust in a group, {#blank#}9{#/blank#}I am sure, they will gradually learn to adjust and work as a team. Effective teamwork motivates an individual to grow into a responsible citizen, and accomplish individual as well {#blank#}10{#/blank#}organizational goals.

    I am a huge fan of thrift shop (旧货店) and have several that I check out every weekend. It's how I relax and get some time to {#blank#}1{#/blank#} (I). I actually look forward to it every week.

    One of my favorite shops started discounting certain pieces of clothing by 90%. I was {#blank#}2{#/blank#} (disappoint) at first that I couldn't benefit from this, because none of them was in my or my husband's size.

    Then it {#blank#}3{#/blank#} (occur) to me that I could stock up on sweaters and jackets for the coming cold weather and donate them {#blank#}4{#/blank#} the homeless shelter! In the last couple of {#blank#}5{#/blank#} (week) I've gotten six huge bags of clothes for under $20! I try to get unisex (男女皆宜的) colors and styles in case there are women {#blank#}6{#/blank#} need clothing, too.

    I went to the shelter today to drop off the clothing. It was pouring with rain, and there were several people huddled (挤成一团) inside {#blank#}7{#/blank#} (wait) for lunch. One poor man was lying on the wet floor. I asked him {#blank#}8{#/blank#} he wanted something dry to lie on and gave him a sleeping bag. He was thrilled and said he {#blank#}9{#/blank#} (real) needed one.

    Before dropping off the clothing I put {#blank#}10{#/blank#} smile card into one of the jacket pockets!

Eat healthier without quitting sugar

    Not long ago, fat was regarded as the evil for a healthy diet. Before that it was salt. Now the sugar-free diet {#blank#}1{#/blank#} (explode) onto the health scene —and seems to have topped many people's list of New Year's resolutions.

    Sugar-free diets encourage people to avoid sweeteners such as honey, soft drinks and some fruits. Some also recommend {#blank#}2{#/blank#} (restrict) dairy products. The diet's advocates note that excessive sugar consumption may increase the risk of heart disease and some cancers. So many sugar-free followers avoid milk, yoghurt and cheese {#blank#}3{#/blank#} the assumption that these products contain sugars.

    It's true we are swallowing too much of the sweet stuff, with the average American consuming around 20 teaspoons of {#blank#}4{#/blank#} (add) sugar a day. But you don't need {#blank#}5{#/blank#} (quit) sugar for healthy eating. Quitting sugar is unlikely to improve your health any more than cutting down on over-processed foods and eating more vegetables.

    Research shows dieting is not effective over the long term and can lead to greater weight gain over time. The brain interprets dieting and restriction as hunger,  {#blank#}6{#/blank#} causes the storage of fat. Besides, the sugar-free diet is confusing and imposes a set of rules that {#blank#}7{#/blank#} (make) up without scientific evidence. Such a restrictive diet can create food fear or an unhealthy relationship with food. People who worry about food are more likely to diet. This may be {#blank#}8{#/blank#}they are worried about their weight, or about the impact certain nutrients have on their health.

    Through series of experiments, {#blank#}9{#/blank#} the researchers are certain about is that you can eat plenty of plants, enjoy whole grains and beans. Fruit is your friend, not your enemy. Most people could probably eat a little less sugar, a little {#blank#}10{#/blank#} (often), but you don't have to quit it for good to be healthy.
