Question

17．Why is that some people live to be over a hundred，while most of us die much sooner？Well，if your parents and grandparents lived a long time，you have a good chance of living a long time，too．How long you live also depends on where you live．A person who lives in a city in Australia will probably live longer than a person who lives in a poor part of Africa．
  We have no control over oour past relatives，and most people have little control over where they live．So，what can you do to add more years to your life？You can make healthy choice．That means eating healthy foods and getting enough exercise．
  Being overweight may make your life shorter because you have a higher chance to have health problems．As a result，you can start by changing what you eat．Eat less red meat．Instead，eat chicken or fish．Fish is really good for helping you live a longer life．You should also eat lots of vegetables and make sure you are getting all of the vitamins you need．And，of course，do not eat too much junk food．
  You also need to get enough exercise．There are different types of exercise．Some exercise is good for your heart．Other types of exercise are good for making you strong．Lifting weights is a good example．You should try to exercise for about thirty minutes every day．
  You should take care of your body，also you have to take care of your mind．Don't work too hard．Try to relax and do something fun each day．If you follow these rules，you have a good chance of living a long time．

Answer 1

分析 文章大意：本文是一篇说明文．文章主要讲述了什么样的人才能更长寿．提到了影响人们寿命的主要因素有：遗传、饮食健康、锻炼以及不能工作太累．只有这样做，才有机会活得更久一些．

解答 52．答案：A．词意猜测题．题第二段可知我们不能控制我们的遗传，但是我们可以通吃健康的饮食和锻炼来延长生命．所以说这句话的意思是"活得更久一些"．故选A．
53．答案：C．推理判断题．根据文章第四段句子"Other types of exercise are good for making you strong．"Lifting weights is a good example．其他类型的锻炼有益于使你强壮．举重是一个很好的例子．可知举重是一种使人们强壮的锻炼．故选C．
54．答案：B．推理判断题．根据第二行How long you live also depends on where you live．你活多久还取决于你住在哪里．可知，C选项与长寿有关．根据第二段第一句We have no control over oour past relatives，and most people have little control over where they live．我们无法控制我们的遗传，大多数人几乎无法控制他们住在哪里．可知，A选项与长寿有关．根据最后一段You should take care of your body，also you have to take care of your mind．Don't work too hard．Try to relax and do something fun each day．你应该照顾好你的身体，也要好好照顾你的心态，不要工作得太辛苦，尽量放松，每天做一些有意思的事情．可知，D选项与长寿有关．因此，一个更长的生命与"一个人的知识"是无关的．B选项"一个人的知识"．文章里没有提到．所以选B．
55．答案：C．主旨大意题．根据最后一句If you follow these rules，you have a good chance of living a long time．如果你遵守这些规则，你就有很好的机会活很长时间．及整篇文章来看，文章重点讲解了如何长寿．所以选C．
