19．As weather cools across the United States.a growing number of Americans visit farms．They harvest ——青夏教育精英家教网—

19．As weather cools across the United States，a growing number of Americans visit farms．They harvest fruits，enjoy hay wagon rides and walk in the fields．These people are called"agri-tourists．"They improve the economy of rural areas and help farmers increase their profits．
School children are walking in a corn field maze．The corn is cut into tricky passageways that make it difficult to find a way out．The children are from Yorktown Elementary School in Bowie Maryland．They have traveled to Montpelier Farms in Prince George's County which is also in Maryland．The farm is about 40kilometers from The White House．
Debbie Pierson is the student's teacher．"We go on these kind of field trips so that the children will have a hands-on experience of what it's like to be on a farm，"Pierson said．
In Loudoun County Virginia，there are farms where grapes are grown for use in making wine．Many of the farms let people visit，and drink the wine that is made there．Bill Hatch owns the Zephaniah Farm Vineyard．He holds wine tastings in his home．"We are doubling the number of visitors to our farm every year．We have an average of 250people on a weekend，"Hatch said．
As more people visit farms，more farmers are adding activities in which visitors can take part．
Malcolm Baldwin owns WeatherLea Farm and Vineyard in Loudoun County．Six years ago，he began letting people be married at his farm．They can also sleep at the farm overnight．Mr．Baldwin says the money he makes from these activities let him keep his small farm operating．"But without the animals，and without the vines，the wedding business wouldn't be as profitable （有利可图的），because people like to see the vines．They like to see the animals and without which I don't think this will be a popular place，"Baldwin said．

18．As many as one in five US teenagers have some degree of hearing loss，according to researchers．
They say the problem is growing．
Teenagers really don't pay attention to how much noise they are exposed （暴露） to，Josef Shargorodsky of Brigham and Women's Hospital in Boston told Reuters．"Often people won't notice it，but even slight hearing loss may affect language development，"said Shargorodsky，one of the researchers．
The study compared surveys from the early 1990s and the mid-2000s．Each included a few thousand teenagers．In the first survey，about 15percent of teenagers had some degree of hearing loss．Some 15years later，that number had risen by a third，to nearly 20percent．
"This certainly is big news，"said Alison Grimes，an ear doctor．Hearing loss is very common in old people，Grimes said，but she added that it was worrying to see it happen in the younger age group．
In babies and young children，hearing problems are known to slow language development．The science is less clear for teenagers，but it is easy to imagine how being hard of hearing could affect learning，said Grimes，．
The reasons for the rise are still unclear．When researchers asked teenagers about noise exposure-on the job，at school or from activities，for example-the teenagers didn't report any change．But Shargorodsky said that might not be true．"We knew from before that it is difficult to ask this age group about noise exposure-they underestimate （低估） it．"Few people would call it noise when they listen to music on their MP3player，for example．"There is a difference between what we think is loud and what is harmful to the ear，"said Grimes．
Although it's not clear that the MP3 players cause teenagers'hearing loss，Grimes said it was still a good idea to turn down the sound and take short breaks from listening．

29．According to the researchers，in a US class of 40students，aboutD students have some degree of hearing loss．

C．suggest that teenagers shouldn't listen to loud music
D．show how important hearing can be for learning．

17．If you want to express something so unbelievable that it must have been a special effect，you have a new word to add to your vocabulary．
It's"Duang"，an onomatopoetic （拟声词） word which doesn't relate to any particular Chinese character and refers to a special effect．
A video parody （恶搞） adapted from a shampoo commercial featuring Hong Kong actor Jackie Chan spread quickly online，leading Internet users to invent the new word．
The video begins with Chan flashing his black，smooth hair，which would have been perfect except that it was not his real hair．
Next，a self-satisfied Chan admits，to the repetitive，rhythmical sounds of"Duang"，"I refused to approve of this product when they first came to me because of my thin hair，but the director insisted，saying special effects could be used to make my hair look healthy on the screen．Now you see，it's all special effects．It's not real．"
The original advertisement became the target of punishment by the government for over-spreading the effects of the shampoo after it was broadcast in 2004．
"Duang"has now become one of the hottest topics on Sina Weibo，a Twitter-like Chinese social network site among those crazy ones imitating Jackie Chan's speech in different situations．
The actor's Weibo account was flooded with comments containing the word in this sweeping online trend．
The video came at a time when the famous movie star has been under public attention after trying to save the ill image of his son，Jaycee Chan，who was released from prison this week．
Data from Baidu，the major Chinese search engine，also proved the phrase's popularity as it has been searched more than 586，000times within two days．
The word of geili's sudden rise in 2010caught the attention of international media when it made up for the word's official translation-geilivable-to describe something cool or awesome．
It's not the first time that online word has become a regular vocabulary in China．

29．From the passage we know that the word"Duang"was originally madeC．
A．by some crazy Internet users
B．to refer to a kind of product
C．by Hong Kong actor Jackie Chan
D．to expresssome special meaning
30．From the passage we know that the new word"geili"isD．
A．only popular in China B．a cool and awesome word
C．used by ordinary people D．also widely used abroad
31．What is the purpose of the author in writing the passage？A
A．To tell us online words have enriched Chinese vocabulary．
B．To teach all the Internet users how to invent new words．
C．To explain how Jackie Chan invented the popular word．
D．To urge people to fight against the false advertisements．

16．More than 2.25billion cups of coffee are consumed across the globe each day，and it's likely that many taste bitter．
Now，a new study suggests that coffee fans can make their drink taste sweeter by simply swapping the color of their coffee cups．
Scientists from Federation University Australia and the University of Oxford claim that blue and glass cups，which are popular in some coffee shops，reduce a coffee's bitterness，without any need for sugar and that coffee drunk from white cups tastes bitterest．
To prove their claims，the researchers invited 36volunteers and used three different colored cups-blue，white and transparent glass-to do experiments．
In the experiment，coffee consumed from the white cup was found to taste less sweet when compared to the other two colored cups，while the blue cup made the coffee taste the sweetest．
The scientists believe that the color brown may be associated with coffee's bitterness because coffee in a white cup appears the brownest and tastes bitterest．
"Our study clearly shows that the color of a coffee mug does influence the perceived taste and flavor of coffee，"said the lead author Dr George Doorn of Federation University Australia，"but the potential effects may be different between a one-time purchase and a return customer．"
"Anyhow，the effect of the mug's color on the flavor of the coffee suggests that café owners，baristas，as well as coffee mug manufacturers should carefully consider the color of their mugs，"he added．
However，the idea that color can alter the taste of food and drink is not new．
A study published last year revealed that red，strawberry-flavored mousse （慕斯蛋糕） served on a white plate was 10percent sweeter and 15percent more flavorful than the same food presented on a black plate．

63．What color of the cup can best reduce coffee's bitterness without adding sugar？A
A．Blue．
B．Brown．
C．White．
D．Transparent．
64．The scientists usedB to do the experiment to prove their claims．

②different-colored coffee cups
③several volunteers
④several manufacturers
A．①②
B．②③
C．②④
D．③④
65．Why does coffee in white cups taste the least sweet？D
A．Because white cups are not as beautiful as other cups．
B．Because white cups are better used to serve cakes．
C．Because white cups reduce the sugar in them．
D．Because white cups make coffee appear the brownest．
66．According to the article，which of the following statement is TRUE？C
A．Black plates increase the sweetness of food and drink．
B．Strawberry-flavored mousse is 10percent sweeter than coffee．
C．People can make coffee taste sweeter by changing the color of their coffee cups．
D．People consume more than 2.5billion cups of coffee across the globe each day．

15．Americans use many expressions with the word"dog"．People in the US love their dogs and treat them well．They take their dogs for walks，let them play outside and give them good food and medical care．However，dogs without owners lead a different kind of life．The expression"to lead a dog's life"describes a person who has an unhappy life．
Some people say we live in a dog-eat-dog world．That means many people are competing for the same thing，like good jobs．They say that to be successful，they have to work like a dog．This means they have to work very hard．Such hard work can make people dog-tired．And，the situation would be even worse if they became sick as a dog．
Some people say，"Every dog has its day．"This means that every person enjoys a successful period during his or her life．To be successful，people often have to learn new skills．Yet，some people say that you can never teach an old dog new tricks．They believe that old people don't like to learn new things and will not change the way they do things．
Some other people are compared to dogs in bad ways．People who are unkind or uncaring can be described as meaner than a junkyard dog．Junkyard dogs live in places where people throw away things they don't want．But mean dogs are often used to guard the property，for they bark at or attack people who try to enter the property．However，sometimes a person who appears to be mean and threatening is really not so bad．We say his bark is worse than his bite．
Dog expressions are also used to describe the weather．The dog days of summer are the hottest days of the year．A rainstorm may cool the weather，but we don't want it to rain too hard．We don't want it to rain cats and dogs．

14．Birds can learn to choose the best building materials for their nests，according to scientists．
It was previously thought that birds'choice of nest materials was determined by their genes，that is，each type of bird has their own methods of building nests born with them．But an experiment has now shown this to be a more complex activity．This study，published in the Royal Society Journal Proceeding B，involved giving zebra finches （斑胸草雀） a choice of soft and hard string to build the their nests．"We found that they liked the harder string，"explained the lead researcher Dr Bailey from the University of St Andrews．"It's more efficient for them to build with-they can build a nest with fewer materials．"
Dr Bailey and her colleagues were planning to test the learning ability of birds； their test aimed to work out if the birds could learn to tell the difference among the materials based on their quality．To test this，they gave one group of finches flexible，soft string to build with，and another group harder string．Both groups of birds were then offered a choice between the soft and hard string．And the birds that had been made to build their nests with the soft string immediately chose the more rigid building materials．
"There is a great diversity of nests in the natural world，"said Dr Bailey．"And because birds are not considered to be as clever as people，who can learn to use different materials quite easily，the assumption had been that there was a genetic pattern in the birds'brains．"
"This shows that actually learning is also very important for their decisions．"Mike Toms from the British Trust for Ornithology said the research made a lot of sense．
"It may help to explain the variety of materials that may be used by individuals of the same species nesting in the same general area．"He told BBC news．

55．What is the purpose of the experiment mentioned in the text？D
A．To make sure finches can use different building materials like people．

11．A sunflower is a sunflower．A mobile phone is a mobile phone．But can you combine the two to do something for your local environment？As early as next year it may well be possible．When you have finished with your mobile phone you will be able to bury it in a garden or a plant pot and wait for it to flower．
A biodegradable （生物所能分解的） mobile phone was，this month，introduced by scientists．It is hoped that the new type of phone will encourage consumers to recycle．
Scientists have come up with a new material over the last five years．It looks like any other plastic and can be hard or soft，and is able to change shape．Over time it can also break down into the soil without giving out any poisonous chemicals．British researchers used the new material to develop a phone cover that contains a sunflower seed．When this new type of cover turns into waste，it forms fertilizers．These feed the seed and help the flower grow．
Engineers have designed a small transparent （透明的） window to hold the seed．They have made sure it only grows when the phone is thrown away．"We've only put sunflower seeds into the covers so far．But we are working with plant experts to find out which flowers would perform best．Maybe we could put roses in next time，"said one scientist．
As phone technology is developing so quickly，people are constantly throwing their mobiles away．This means manufacturers are under pressure to find ways of recycling them．Some 650million mobile phones have been sold this year．Most of them will be thrown away within two years，adding plastic，heavy metal and chemical waste to the environment．A biodegradable cover can offer some relief for nature，according to the scientists．
"The seed comes out and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it，"said Kerry Kieran．She leads the research team，which is based at the University of Warwick in Britain．
72．What is the purpose of this passage？B
A．To tell the popularity of biodegradable cell phones．

10．All around the world，more and more people are donating their time to take part in online volunteering projects．What motivates them to help strangers without expectation of money or even thanks？
Radha Taralekar helped teach Imelda how to protect herself from HIV，though the two have never met，and neither knows the other's name．From her home Mumbai，the young woman took several weeks to write a guide especially for Imelda-who lost her children to HIV/Aids in Uganda．Taralekar received no payment for the job．Taralekar is one of a number of talented people who regularly donate their time online．But what is driving them to help total strangers，while asking for nothing in return？For Taralekar，the project gave her the chance to use her professional experience．"I want to serve people with my medical knowledge，"she says．
For some，the inspiration to volunteer online was far more personal．After losing his wife to cancer，Tony Selman spent many hours online helping Cancer Research to collect data on the disease．"Seeing how painful she was when my wife was dying，I determined to help scientists find a cure for cancer，"he says．
Interests and hobbies are also one of the factors．In 2011Sam Luk，a designer，joined other online volunteers to try to help the police solve a murder case．Twelve years earlier the body of Ricky McCormick had been found killed in a field in St Louis，Missouri-the only clues being two encoded （被译成密码的） letters found in his pockets．Unable to decipher （破译） the codes，the police posted them online，calling for volunteers to help them make sense of the messages．"I'm interested in patterns and I love Sherlock Holmes，"says Luk．He spent hours every week trying to decrypt the notes，but the case remains unsolved to this day．
For writer Clay Shirky，some large online volunteering projects benefit millions of people，giving him a sense of achievement and generosity．He helps write Wikipedia，the world's biggest encyclopedia （百科全书），which is written entirely by people willing to donate their professional knowledge without any reward．
