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．
52．How do you explain"to add more years to your life"in paragraph 2？A 
A．To live longer 
B．To live shorter．
C．To live better．
D．To live worse．
53．In the writer's opinion，lifting weights is good exerciseC．
A．to our heart   
B．to our mind 
C．to make us strong 
D．to make us relax
54．According to the passage，a longer life has nothing to do withB．

D．ways of life
55．What's the passage mainly about？C

分析 文章大意：本文是一篇說明文．文章主要講述了什么樣的人才能更長(zhǎng)壽．提到了影響人們壽命的主要因素有：遺傳、飲食健康、鍛煉以及不能工作太累．只有這樣做，才有機(jī)會(huì)活得更久一些．

解答 52．答案：A．詞意猜測(cè)題．題第二段可知我們不能控制我們的遺傳，但是我們可以通吃健康的飲食和鍛煉來延長(zhǎng)生命．所以說這句話的意思是"活得更久一些"．故選A．
53．答案：C．推理判斷題．根據(jù)文章第四段句子"Other types of exercise are good for making you strong．"Lifting weights is a good example．其他類型的鍛煉有益于使你強(qiáng)壯．舉重是一個(gè)很好的例子．可知舉重是一種使人們強(qiáng)壯的鍛煉．故選C．
54．答案：B．推理判斷題．根據(jù)第二行How long you live also depends on where you live．你活多久還取決于你住在哪里．可知，C選項(xiàng)與長(zhǎng)壽有關(guān)．根據(jù)第二段第一句We have no control over oour past relatives，and most people have little control over where they live．我們無(wú)法控制我們的遺傳，大多數(shù)人幾乎無(wú)法控制他們住在哪里．可知，A選項(xiàng)與長(zhǎng)壽有關(guān)．根據(jù)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．你應(yīng)該照顧好你的身體，也要好好照顧你的心態(tài)，不要工作得太辛苦，盡量放松，每天做一些有意思的事情．可知，D選項(xiàng)與長(zhǎng)壽有關(guān)．因此，一個(gè)更長(zhǎng)的生命與"一個(gè)人的知識(shí)"是無(wú)關(guān)的．B選項(xiàng)"一個(gè)人的知識(shí)"．文章里沒有提到．所以選B．
55．答案：C．主旨大意題．根據(jù)最后一句If you follow these rules，you have a good chance of living a long time．如果你遵守這些規(guī)則，你就有很好的機(jī)會(huì)活很長(zhǎng)時(shí)間．及整篇文章來看，文章重點(diǎn)講解了如何長(zhǎng)壽．所以選C．

點(diǎn)評(píng) 閱讀題型，要注重句子與句子之間、段落與段落之間邏輯關(guān)系以及對(duì)篇章的整體理解．根據(jù)所給問題選擇正確選項(xiàng)完成試題．

8．任務(wù)型閱讀
閱讀下列短文，根據(jù)短文中的信息完成文后表格．（每空一詞）
In the past，man did not have to think about the protection of his environment．There were not many people on earth，and natural resources seemed to be unlimited．
Today，things are different．The world has become too crowded．We are using up our natural resources too quickly，and at the same time we are polluting our environment with dangerous chemicals．If we continue like this，human life on earth will not survive．
Everyone realizes today that if too many fish are taken from the sea，there will soon be none left．Yet，with modern fishing methods，more and more fish are caught．We know that if too many trees are cut down，forests will disappear and nothing will grow on the land．Yet，we continue to use bigger and more powerful machines to cut down more and more trees．
We realize that if rivers are polluted with waste products from factories，we will die．However，in most countries waste products are still put into rivers or into the sea，and there are few laws to stop this．
We know，too，that if the population of the world continues to rise at the present rate，in a few years，there will not be enough food．
What can we do to solve these problems？
If we eat more vegetables and less meat，we will easily get more food．Land that is used to grow crops can feed five times more people than land where animals are kept．
The world population will not rise so quickly if people use modern methods of birth control．
Finally，if we educate people to think about the problems，we shall have a better and cleaner living place in the future．

The importance of protecting the environment
Problems◆More fish being caught．
◆More （61）trees  being cut down．
◆More waste products being put into rivers．
◆More （62）babies  being born．
Causes◆The world is becoming too （63）crowded．
◆Modern methods make the situation worse．
ResultWe human beings will not survive on the earth．
Solutions◆Eat more vegetables and less meat so that more food will be
available  for everyone．
◆Use modern methods of （64）birth  control so that the population will not grow too fast．
◆Educate people so that the （65）earth  will be better and cleaner．

9．Many Americans have been leaving their cars at home and riding to work on bicycles．Andy Clark is the leader of the League of American Bicyclists．His group supports bicycling for fun，fitness and transportation．
Clark says this is good news for the environment．He says riding a bicycle to work does not burn fossil fuel （能源） or creates dangerous pollutions．Experts say the effects are the most important on short trips．The Department of Transportation says fifty percent of Americans drive eight kilometers or fewer to work．Shorter car trips set out more pollution into the air for each kilometer drive．This is because the car engine will set out the harmful air when it warms up before it can work well．
James，a member of Congress （國(guó)會(huì)），is a strong supporter of bicycle use．He says cities，counties，state governments and state highway transportation agencies are planning the roadways of the future．They are creating roads and paths for bicycles in cities and between communities．
Last year，Portland，the Pacific Northwest city in the state of Oregon，had the highest percentage of bicycle users in the United States．Portland has been doing progressive city planning for many years to create special paths for bike riders．
