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.

    Here is a message that needs to {#blank#}1{#/blank#}(keep) in mind by every mom and dad. You love your kids not because of{#blank#}2{#/blank#}they do, but because of who they are.

    In fact, raising a child is just like training a dog. You reward your children because of their

    {#blank#}3{#/blank#} (succeed) or progress they made.{#blank#}4{#/blank#} (similar), a circus trainer gives a dog some food every time it {#blank#}5{#/blank#}(jump) through a hoop (圈).

The dog isn't loved for itself,{#blank#}6{#/blank#} for its actions.

    Dr. Laura Schlessinger, the popular talk show host, has a new book for children{#blank#}7{#/blank#} (title) Why Do You Love Me?

    Jane was walking round the department store. She remembered how difficult {#blank#}1{#/blank#} was to choose a suitable Christmas gift for her father. She wished that he was as easy {#blank#}2{#/blank#} (please) as her mother, who was always delighted with perfume.

    Besides, shopping at this time of the year was not {#blank#}3{#/blank#} pleasant experience：people {#blank#}4{#/blank#}（step）on your feet or pushed you with their elbows (肘部), hurrying ahead to get to a bargain.

    Jane paused in front of a counter {#blank#}5{#/blank#} some attractive ties were on display. "They are real silk," the assistant tried to attract her. "Worth double the price." But Jane knew from past experience that her {#blank#}6{#/blank#} (choose) of ties hardly ever pleased her father. Jane stopped where a small crowd of men had gathered. She found some good quality pipes {#blank#}7{#/blank#} sale. She did not hesitate for long: although her father smoked a pipe only once in a while, she knew that this was a present which was bound to please {#blank#}8{#/blank#}.

    When Jane got home, with her small but well-chosen present in her bag, her parents were already {#blank#}9{#/blank#} table having supper. Her mother was excited. "Your father has at last decided to stop smoking," Jane {#blank#}10{#/blank#} (inform).

    "Living within 300 metres of green space {#blank#}1{#/blank#} (associate) with greater happiness, sense of worth and life satisfaction," says a new study. {#blank#}2{#/blank#} (use) data from UK government's Annual Population Survey (APS) of 25518 people, the researchers show that people {#blank#}3{#/blank#} live within 300 metres of green space have significantly better mental well-being. "A lot of research focuses {#blank#}4{#/blank#} poor mental health, or single aspect of well-being like life satisfaction. What makes our work different is the way we consider multi-dimensional mental well-being in terms of happiness, life satisfaction and worth," said Victoria Houlden from the University of Warwick.

    The study, {#blank#}5{#/blank#} (publish) in the journal Applied Geography, found that there is a very strong relationship between the amount of green space around a person's home {#blank#}6{#/blank#}  their feelings of life satisfaction, happiness, and self-worth. Green space within 300 metres of home made the greatest {#blank#}7{#/blank#} (differ) to mental well-being. The study found that access to green space was {#blank#}8{#/blank#} (important) than lifestyle factors such as employment, income and general health. "By {#blank#}9{#/blank#} (combine) advanced statistical and mapping methods, we've shown that the effect is real. {#blank#}10{#/blank#} (basical) we've proven what everyone has always assumed was true," said Scott Weich, Professor at the University of Sheffield.
