6.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 how just three grams less a day would affect heart disease in the United States.
The result:10% fewer heart attacks.8% fewer strokes.4% fewer deaths.11% fewer new cases of heart disease.And 240billion dollars in health care savings.
Researchers found it could prevent 100,000heart attacks and 92,000deaths every year.
The study is in the New England Journal of Medicine.Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author.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 Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium(鈉),which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day.The American Heart Association advises no more than three grams for healthy people.It says salt in the American diet has increased by fifty percent since the 1970s,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.Critics call it government interference.Mayor Bloomberg has already succeeded in other areas,like requiring fast food places in the city to list calorie information.Now a study by the Seattle Children's Research Institute shows that the calorie information on the menu can influence what parents order for their children.

分析 本文通過一項(xiàng)調(diào)查告訴我們食鹽與很多疾病的關(guān)系,呼吁我們少攝入食鹽.同時(shí)介紹了The National Salt Reduction Initiative以及Bloomberg等組織及個(gè)人在這方面做出的努力.
解答 32-35ABCD
32 A 細(xì)節(jié)題.根據(jù)文章第二段The result:10% fewer heart attacks,8% fewer strokes,4% fewer deaths,11% fewer new cases of heart disease,and 240 billion dollars in health care savings.可知BCD三種疾病都是和食鹽攝入過多有關(guān)系的.只有A項(xiàng)沒有提及.故A正確.
33 B 推理題.根據(jù)文章第五段Each gram of salt contains four hundred milligrams of sodium(鈉),which is how foods may list their salt content.可知食物中食鹽的含量是用sodium(鈉)的量來衡量的.故B正確.
34 C 細(xì)節(jié)題.根據(jù)文章倒數(shù)第二段New York City Mayor Michael Bloomberg is leading effort called the National Salt Reduction Initiative.The idea is to put pressure on food companies and restaurants.Critics call it government interference.可知the National Salt Reduction Initiative.的目的就是向食品公司或餐廳施加壓力,讓他們減少食鹽的使用.故C正確.
35 D 段落大意題.根據(jù)本段中心句第一句Mayor Bloomberg has already succeeded in other areas,like requiring fast food places in the city to list calorie information可知本段講述的是Mayor Bloomberg在其他方面做做的努力.故A正確.
點(diǎn)評(píng) 做閱讀理解時(shí)要快速的瀏覽全文,把握文章主旨大意,帶著問題回到原文,尋找細(xì)節(jié)或概括相應(yīng)的答案,最后要理清作者寫作思路.
