问题 单项选择题

环境学有关保护濒临灭绝的动物的高昂费用,提出应通过评估各种濒临灭绝的动物对人类的价值,以决定保护哪些动物。此法实际不可行,因为,预言一种动物未来的价值是不可能的。评价对人类现在做出间接但很重要贡献的动物的价值也是不可能的。从这段文字中可以推出的是()

A.保护对人类有直接价值的动物远比保护有间接价值的动物重要

B.保护没有价值的濒临灭绝的动物比保护有潜在价值的动物更重要

C.尽管保护所有濒临灭绝的动物是必须的,但在经济上却是不可行的

D.由于判断动物对人类价值高低的方法并不完善,在此基础上做出的决定也不可靠

答案

参考答案:C

解析:题干中指出,通过评估各种濒临灭绝的动物对人类的价值以决定保护哪些动物的方法不可行,其隐藏的含义是:所有濒临灭绝的动物都应受到同等的保护.但是,从“高昂费用”一词可以看出,保护所有濒临灭绝的动物在经济上却不可行.由此,可确认C项是正确选项.A项与B项都明显与题干所述矛盾,不应选.D项也是错误的,题干中是讲“此法实际不可行”,而不是此法不完善、不可靠.

     Few days ago, I went to school with tons of books, hoping to get a locker. All of a sudden, it started
raining   1  . I hurried to pay for my locker, but I was disappointed   2   they informed me that they only
accepted cash. I was $7.00   3  , which meant I had to carry the books back home. It would be an
exhausting two-hour   4   back home with all those books.
     There was an elderly gentleman nearby.   5   my predicament (困境), he asked me how much cash I
needed. When I told him I needed $7, he quickly took out the money. "You don't have to pay me back,"
he said. I was   6  . I didn't know whether to take the money or come back with the books the next day.
A young student who was working there noticed my   7  . "He is really nice," said the student, "I was
starving this moming and he bought   8   for me. He always helps people in different ways."   9   thinking
for a while, I took the money and  10  my locker.
     The next day, I went to him and thanked him for  11  me and lending me the money. He said he forgot
about it and did not  12  that I would give it back. "I am very happy," he said, "not because I am getting
my money back,  13  because this is the right way to go whatever you get  14  this world, give it back as
much as you possibly can. Spread kindness around the world  15  the smallest things you can do,"
     Later, I found out that he was not involved with any charity  16 . He has been performing these types
of  17  for years. I desperately needed the locker that day but after meeting this man, I was much more 
 18  for meeting him than getting my locker. He taught me a very important  19  in life-we come to this
world with nothing and we will leave with nothing. Whatever we own, it  20  someone else and whatever
we leave, it will become somebody else's.
