17.Frozen fruit and vegetables can be healthier,with higher levels of vitamins and cancer fighting antioxidants (抗氧化剂),that leafy"fresh"produce.Two independent studies found more beneficial nutrients in everything from frozen broccoli florets to carrots.In two out of three cases frozen fruit and vegetables scored better on antioxidant-type compounds(化合物).Consumption of these antioxidant compounds is considered beneficial in preventing cancer and supporting the wording of the body,brain,skin and eyes.
Produce bought from the supermarket greengrocer sections is full of color,while many stores even use fine mist sprays (喷剂)to give a just picked look.This supermarket theatre convinces shoppers to pay an extra payment for food that they believe is good for their family's health as well as being tasty.However,the reality is that these vegetables and fruit may well have been held in storage for a month,while they then sit in the fridge at home for days before being eaten.
Over the days,they gradually  deteriorate,slowly losing some of the nutrients associated with leafy greens and fruit.By contrast,frozen vegetables and fruit are chilled(冷藏)soon after harvest and so keep higher levels of vitamins and antioxidants until they are eaten.
Two teams,one from Leatherhead Food Research and the other from the University of Chester,carried out 40tests to measure nutrient levels in produce which had been sitting in a fridge for three days and the frozen equivalent (相等物).The findings show that eating newly picked produce is the healthiest option; however,frozen food can be almost as good and is often better than items sold as"fresh".Leatherhead's Dr Rachel Burch said:"We must ignore the mistaken opinion that fresh food is always better for us than frozen food."
These results show that frozen food can be nutritionally comparable to fresh produce.Direct comparison:In two out of three cases frozen fruit and vegetable scored better on antioxidant-type compounds including Vitamin C,polyphenols and anthocyanins (多酚和花青素),a study found.Her team found frozen broccoli had higher levels of Vitamin C.However,fresh food scored better on polyphenols,which are thought to help prevent cancer.
32.What does the passage mainly tell us?D
A.Fresh food is better than frozen food
B.Frozen food might cause cancer.
C.Frozen food is as good as fresh food
D.Frozen food is better than"fresh"food.
33.Why do some supermarkets spray fine mist on fruit and vegetables?C
A.To keep them in good quality
B.To make them taste good.
C.To make them look fresh
D.To make them sell cheaply.
34.What does the underlined word"deteriorate"in Paragraph 3mean?A
A.Grow worse
B.Grow better.
C.Remain the same
D.Die out.
35.What is more helpful in preventing cancer?C
A.Vitamin C
B.Frozen fruit and vegetables.
C.Fresh fruit and vegetables
D.Anthocyanins.

分析 本文介绍了冷冻食品比新鲜食品在某些方面更健康.

解答 32-35.DCAC
32.D主旨大意题.文章开篇点题Frozen fruit and vegetables can be healthier,with higher levels of vitamins and cancer fighting antioxidants (抗氧化剂),that leafy"fresh"produce.冷冻水果和蔬菜更健康,比"新鲜"果蔬所含的维生素和抗癌氧化剂水平高.故本题答案为D选项.
33.C细节理解题.根据第二段"many stores even use fine mist sprays (喷剂)to give a just picked look.…However,the reality is that these vegetables and fruit may well have been held in storage for a month,while they then sit in the fridge at home for days before being eaten."许多商店甚至给蔬菜水果喷雾打湿看似是"新采摘"的.不过,实际上这些蔬菜和水果都有可能已经存放了一个月,又在家里的冰箱里放了好几天才吃.由此可知,超市给果蔬喷雾是为了使它们看起来新鲜;故本题答案为C选项.
34.A词义猜测题.根据画线词下文"slowly losing some of the nutrients associated with leafy greens and fruit.绿叶蔬菜和水果逐渐失去某些营养素.由此可猜蔬菜和水果逐渐变坏,故本题答案为A选项.
35.C细节理解题.根据最后一段"However,fresh food scored better on polyphenols,which are thought to help prevent cancer."不过新鲜的果蔬多酚类物质含量较高--多酚类物质被认为有助于预防癌症.故本题答案为C选项.

12.ottled water has become the choice for people who are healthy and thirsty.Bottled water is all over the world.But some say the planet's health,and people's health may be suffering from it.
The idea that bottled water is safer for humans may not be true.The Natural Resources Defense Council of America said,"There is no promise that because water comes out of a bottle,it is cleaner or safer than water from the tap."Another New York City-based action group added that some bottled water is"really just tap water in a bottle-sometimes more clean,sometimes not."
It is not proven that bottled water is better than tap water.Nick Reeves from the Chartered Institution of Water and Environmental Management said,"The high mineral content(含量) of some bottled water makes them not good for feeding babies and young children."Also,most bottled water doesn't have fluoride(氟化物),which can make teeth stronger.Kids are drinking more bottled water and less fluoridated tap water,and some say that's behind the recent rise in bad teeth.
Storing is another problem.Placed near heat,the plastic bottles can produce bad chemicals(化学物质) into the water.
According to the Environmental Protection Agency,some 2.7million tons of plastic are used worldwide to bottle water each year.The plastic can take between 400and 1,000years to break down.
In terms of energy use,plastic bottles are also not cheap.One report said that if water and soft drink bottlers had used 10percent recycled materials in their plastic bottles,they would have saved about 72million gallons of gas.
So,if you are worried about the effect of bottled water on the Earth,you can take the following steps.
●Drink from your tap.Unless your government warns against this,it should be fine.
●Get a container(容器).Carry your tap water in a steel or a lined drinking container,and clean it between uses.
●Keep it cool.Don't drink from a bottle that has been sitting in the sun,don't store it near chemicals,and don't reuse plastic bottles.
●Choose glass containers over plastic if possible.When finished,recycle!

A.Drinking tap water is the only choice for people.
B.Glass containers are better than plastic bottles.
C.Plastic bottles are harmful to the environment.

2.Flying like a bird has been the dream of humans since ancient times.Last week a group of modern birdmen put their courage on their wings and challenged gravity in Hangzhou,Zhejiang Province.
"Yes,you can buy a ticket and fly to another city.But running with your own wings and feeling your feet ready to take off is totally different,"Dong Fang,said in an excited voice.He is one of 41students from Hangzhou No.14Middle School to test their home-made aircrafts in the playground.Inspired by the International Bognor Birdman Competition in the UK,Ni Wangyue,a teacher in high school is holding a similar event.The Bognor Birdman competition started in 1971in the England coastal city Bognor.People ran off the end of a pier (码头) with their own aircraft in an attempt to"fly"the farthest distance.
"From the very beginning,I didn't expect my students to create a real plane or break any records.I told them the competition is more for seeing how far your imagination can stretch,"Said Ni.He was surprised to see his students create 10different aircrafts with all kinds of material available in the past month.Many students said that they learnt much more in the process of creating their planes than in ordinary classes.
Jing Yuchen and his team named their plane"Weiming E",which means an unknown goose.The 17-year-old boy deeply believes their goose of steel pipe and sailcloth will honour its name by successfully making it fly.
"Our work is much more imaginative than others.With several colourful balloons on its back and a pair of light plastic wings,it surely is the most eye-catching work,if not the best,"said Yu Liang,another student.
"Although most of those home-made aircrafts cannot really take the boys flying,the boys'braveness and creativity in this project will encourage every one of them to fly high in the future,"Ni said.

20.The purpose of the competition is toD.
A.prepare to create more real planes.
B.let students break some records.
C.run off the end of a pier.
D.encourage braveness and creativity.
21.According to the passage,which of the following statements is NOT true?D
A.There were 41students taking part in the competition.
B.A similar kind of competition started in 1971.
C.The teacher didn't expect his students could create 10different aircrafts.
D.Most of those home-made aircrafts could take the boys flying.
22.By saying"you can buy a ticket and fly to another city",the writer actually meansC.
A.if you want to take part in the competition you have to buy a ticket.
B.people who take part in the competition have to fly to another city.
C.people can pay to get a chance to go to another place by air.
D.the students have to fly to another city in their home-made aircrafts.
23.Why did the teacher organize this activity?A
A.He wanted to develop students'imagination.
B.He wanted his students to have the feeling of flying.
C.He wanted his students to break records.
D.He wanted to increase his students'grades.
9.Let's face it.No one drinks diet sodas for the taste.People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect,according to a new study.
Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas."What we saw was that the more diet sodas a person drank,the more weight they were likely to gain,"said Sharon Fowler.
The study was based on data from 474participants in a large,ongoing research project,where the participants were followed for nearly 10years.
While the findings are surprising,they also offer some explanations.
Nutrition expert,Melanie Rogers,who works with overweight patients in New York,has found that when patients are switched from regular to diet sodas,they don't lose weight at all."We weren't seeing weight loss necessarily,and that was confusing to us,"said Rogers.
So why would diet soda cause weight gain?No one knows for sure yet,but it could be that people think they can eat more if they drink diet sodas,and so over-compensate for the missing calories.
A related study found some sweeteners (甜味剂)raised blood sugar levels in some mice."Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky,"said Helen P.Hazuda,professor at School of Medicine of the University of Texas."They may be free of calories,but not of consequences."

25.People drink diet sodas toC.
A.enjoy its taste        
B.stay in fashion
C.achieve weight loss   
D.gain more energy
26.We can learn from the passage thatB.
A.regular sodas make people lose more weight
B.diet soda drinkers tend to eat more food
C.diet sodas do help reduce calories
D.most blood diseases come from diet sodas
27.The underlined word"They"in the last paragraph probably refers to"B".
A.sweeteners
B.diet sodas and artificial sweeteners
C.sodas
D.diet soda drinkers and sweetener takers.

7.The cheapest room and board in Jefferson City,Missouri,over the weekend was at the county jail(监狱),and 170 people gladly checked in.Cole County charged $ 30 a night for anyone who volunteered to go behind bare on Friday or Saturday night.So officials could give the new jail a test run before it opened for real this week.People from three states spent the night at the jail,including some lawyers and a couple celebrating their first anniversary. 
"It was something they could experience without having to get a criminal record,"Cole County Sheriff (治安官)Greg White said."They spent the night and gained all understanding that they would not want to ever do this again."
Jailers tried to give the citizens the full experience.They were told to give up their jewelry,cell phones,and other personal belongings.They were booked and photographed and led into the jail commons. They could keep their cell doors open,but that trapped feeling was still there because me outer room doors were locked,said Bob Watson,60,a reporter for the Jefferson City News-Tribune who spent Friday night at the jail."While it was not a true copy of jail,you got some sense of what it's like to hear that door lock behind you,"Watson said.
Two other feelings were boredom and a lack of choice,illustrated by the television being left on one channel and drowned out anyway by everybody talking.
Bed was a steel bunk with a thin mattress (垫).Overhead,a 40-watt bulb stayed lit through the night in each cell.Handy for guards to see inmates,but not helpful to good sleep.How about the food?Dinner Friday night included cheesy pasta with turkey bits and coffee cake."I wouldn't pay for it in a restaurant,but you won't die trying to eat it,"Watson said.

58.The underlined phrase"illustrated by…"is used toC.
A.introduce a new topic                B.draw a conclusion
