题目内容

13．Even a small reduction in salt in the diet can be a big help to the heart．A new study used a computer model to predict（预测） how just three grams less a day would affect heart disease in the United States．
The study is in the New England Journal of Medicine．Kirsten Bibbins-Domingo at the University of California San Francisco，is the leader of the research team．She says people would not even notice a difference in taste with three grams，or one-half teaspoon，less salt per day．The team also included researchers at Columbia University，like Weston Forbes．
The result：ten percent fewer heart attacks．Four percent fewer deaths．Eleven percent fewer new cases of heart disease．And two hundred forty billion dollars in health care savings．Thus it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．
The government says the average American man eats ten grams of salt a day．Michael swan from the American Heart Association advises no more than three grams for healthy people．It says salt in the American diet has increased fifty percent since the nineteen seventies，while blood pressures have also risen．Less salt can mean a lower blood pressure．
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative．The idea is to put pressure on food companies and restaurants．Mayor Bloomberg has already succeeded in other areas，like requiring fast food places in the city to list calorie information．Now a study shows how that idea can influence（影响） what parents order for their children．

53．How much salt did Americans take in per day on average in the 1970s？C
A．Three grams． B．Five grams．
C．Seven grams． D．Ten grams．
54．Who is head of the team studying the relation between salt reduction and heart attack？A
A．Kirsten Bibbins-Domingo．
B．Michael Bloomberg．
C．Michael Swan．
D．Weston Forbes．
55．The text mainly tells us thatB．
A．cutting salt intake can save more money
B．eating less salt means more healthy life
C．cutting salt intake helps reduce calories
D．eating less salt can cure heart disease
56．According to the text，we may conclude thatC．
A．eating salt less than 3grams makes much difference in taste
B．the American government thinks little of salt reduction
C．more salt in the daily diet may result in higher blood pressure
D．100，000Americans die from higher blood pressure each year．

分析本文通过一项调查告诉我们食盐与很多疾病的关系，呼吁我们少摄入食盐．同时介绍了The National Salt Reduction Initiative以及Bloomberg等组织及个人在这方面做出的努力．

解答 53-56 CABC
53．C．细节理解题．根据第三段The government says the average American man eats ten grams of salt a day．以及It says salt in the American diet has increased fifty percent since the nineteen seventies，可知，现在美国人的饮食中盐的食用比20世纪70年代增加了50%，也就是说在那时食盐的食用大约在7克左右；故选C．
54．A．细节理解题．根据第一段以及第二段中Kirsten Bibbins-Domingo at the University of California San Francisco，is the leader of the research team．可知，Kirsten Bibbins-Domingo是这个课题的负责人；故选A．
55．B．推理判断题．根据第一句话Even a small reduction in salt in the diet can be a big help to the heart．以及全文的内容可知，本文主要论述的是减少食盐的摄入有益于我们的健康；故选B．
56．C．推理判断题．根据专家的研究证明以及短文第三段中It says salt in the American diet has increased fifty percent since the nineteen seventies，while blood pressures have also risen．可知，过多的摄入食盐也是高血压增多的一个重要因素；故选C．

点评考查学生的细节理解和推理判断能力．做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确选择．在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．

4．--What kind of car do you want to have？A large 0ne？

8．You spent 300yuan on a pair of cotton gloves．Such a pair of cotton gloves be worth so much．（　　）

18．Tamiflu does not kill but prevents H1N1from further proliferation （繁衍） till the virus limits itself in about 1-2weeks （its natural cycle）．H1N1，like other Influenza A viruses，only infects the upper respiratory tract and proliferates （only） there．The only way of entry are the nostrils（鼻孔） and mouth/throat．In a global epidemic of this nature，it's almost impossible not coming into contact with H1N1．
Contact with H1N1is not so much of a problem as proliferation is．
While you are still healthy and not showing any symptoms of H1N1infection，in order to prevent proliferation，some very simple steps can be practiced：
1．Frequent hand-washing．
2．"Hands-off-the-face"approach．Resist all temptations to touch any part of face （unless you want to eat or bathe）．
3．Gargle（漱口） twice a day with warm salt water （use Listerine if you don't trust salt）．H1N1takes 2-3days after initial infection in the throat/nasal cavity to proliferate and show characteristic symptoms．Simple gargling prevents proliferation．In a way，gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one．Don't underestimate this simple，inexpensive and powerful preventative method．
4．Similar to 3above，clean your nostrilsat least once every day with warm salt water，Which is very effective in bringing down viral population．
5．Strengthen your natural immunity with foods that are rich in Vitamin C．If you have to supplement with Vitamin C tablets，make sure that it also has Zinc to boost absorption．
6．Drink as much of warm liquids as you can．Drinking warm liquids has the same effect as gargling，but in the reverse direction．They wash off proliferating viruses from the throat into the stomach where they cannot survive，proliferate or do any harm．
7．All these are simple ways to prevent，within means of most households，and certainly much less painful than to wait in long queues outside public hospitals．

57．What part of a person's body do H1N1flu viruses mainly infect？B
A．one's lung           B．the upper respiratory tract
C．one's heart           D．one's throat and lung
