8.While sweet treats can be hard to resist,the World Health Organization(WHO) has set new guidelines for people around the world.The guidelines,released on Wednesday,advise that both adults and children cut back on their sugar intake(攝取量)to stay healthy.
In a statement,F(xiàn)rancesco Branca,director of the WHO's nutrition department,said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay(腐爛).
The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk.According to the WHO,there is no reported evidence of negative effects of consuming those sugars.Instead,the new guidelines focus on"added"or"free"sugars.These include sugars that are added to processed foods and drinks such as candy and soft drinks.
Added sugars are sometimes described as"hidden"sugars because they exist in foods we might not think of as sweets,such as honey and ketchup(番茄醬).Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions.
The WHO recommends that people in the United States,Europe and other Western societies should cut their average sugar intake by about two-thirds,or down to just 10% of their overall calories.For developing countries,where dental care is less advanced,the WHO recommends that sugar intake be reduced to 5%.
Scientist Kieran Clarke,of the University of Oxford,notes that for those people who can't shake their love for sweets,getting more exercise is a good solution."If you get enough exercise,you can eat almost anything,"she said"But it's very hard to avoid large amounts of sugar unless all you're eating is fruit and vegetables."
29.What can we learn from the guidelines released by the World Health Organization?D
A.The production of candies should be forbidden
B.There is a connection between sugar intake and bad teeth.
C.Fruit and vegetables contain a lot of sugar.
D.People should cut down on sugar intake for the sake of their health
30.To what level should people in developing countries cut down their sugar intake,according to the WHO?C
A.10%
B.15%  
C.5% 
D.30%
31.We can learn from the text thatD
A.a(chǎn)dded sugar isn't marked on food packages
B.we should drink as little milk as possible as it contains sugar.
C.soft drinks don't contain added sugar
D.the less exercise you do,the fewer sweet things you should eat.

分析 本文講述的是世界衛(wèi)生組織公布的指南建議少攝入人工糖,但該建議不包括天然的蔬果的糖;同時(shí)建議不能控制攝入糖的人,要多運(yùn)動(dòng)保持健康.

解答 29.D 細(xì)節(jié)理解題.根據(jù)第一段最后一句The guidelines,released on Wednesday,advise that both adults and children cut back on their sugar intake(攝取量)to stay healthy.可知,世界衛(wèi)生組織公布的指南建議要減少糖的攝入量.故選D.
30.C 細(xì)節(jié)理解題.根據(jù)倒數(shù)第二段For developing countries,where dental care is less advanced,the WHO recommends that sugar intake be reduced to 5%.可知,世界衛(wèi)生組織建議糖的攝入量減少到5%,故選C.
31.D 推理判斷題.根據(jù)最后一段Scientist Kieran Clarke,of the University of Oxford,notes that for those people who can't shake their love for sweets,getting more exercise is a good solution."If you get enough exercise,you can eat almost anything,"she said"But it's very hard to avoid large amounts of sugar unless all you're eating is fruit and vegetables."可知,如果運(yùn)動(dòng)少就盡量少攝入糖.故選D.

點(diǎn)評(píng) 本文是新聞報(bào)道類閱讀理解.做這類題材閱讀理解時(shí)要求考生對(duì)文章通讀一遍,做題時(shí)結(jié)合原文和題目有針對(duì)性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項(xiàng)選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù)

16.After Doctor Christopher Charles finished his degree,he went to Cambodia.There,he studied a serious condition anemia (貧血癥).People with anemia do not have enough iron(鐵) in their bodies.Charles did blood tests on many people.He discovered something shocking--about ninety 90% of women and children had anemia.He decided to stay and find a solution.
Charles knew that iron medicine is the usual treatment for anemia.But it costs too much money.Research shows that cooking with iron pots(鍋) could help because it would release iron into every meal.But iron pots are heavy and cost too much.Also,food goes bad if left in an iron pot.So he added a metal bar made of iron to a cooking pot.It did not cost much and it did release lots of iron.However,instead of cooking with it,people used it to hold down papers or support a table with a broken leg.
Finally Charles created the iron fish.Fish are part of the culture of Cambodia.People in Cambodia eat fish every day and they believe that fish are lucky.So people are happy to put the iron fish in their cooking pots.The iron fish has helped thousands of people in Cambodia improve their health,and it has also helped the local economy.People who use the fish in their food miss less days at work.And some people even have jobs from the iron fish.
Though more and more people are using the lucky iron fish in Cambodia,anemia is not just a problem in Cambodia but a worldwide problem,which affects one in three people in the world.In some places people do not eat fish.But Charles says this is not a problem."The iron could be in a different form.What is important is that it is right for each culture.Then people will use it,and it will improve their lives."he says.

28.Why did Charles decide to stay in Cambodia?C.
A.He graduated from a university there.
B.He was interested in studying local people in Cambodia.
C.He wanted to find a solution to a health problem with anemia.
D.He himself was suffering anemia.
29.What was the problem with the iron bar for treating anemia?D.
A.It was too heavy and cost too much.
B.It didn't release iron.
C.It could easily made food go bad.
D.People found other uses for it.
30.How did the local people feel about using the iron fish?D.
A.Angry.
B.Puzzled.
C.Shocked.
D.Pleased
31.What can you infer from the last paragraph?D.
A.Anemia is a worldwide problem.
B.The iron fish can be used for treating anemia worldwide.
C.Fish are important part of the culture of Cambodia.
D.A treatment does not work unless it is acceptable.
