20．"Don't get discouraged，Hallie，"Kathy said，comforting her with a hug．"It sounds as if you have a bit of a mystery to solve．Maybe you should do a little spying on Maya．"
Feeling better，Hallie put on her scuba gear（潜水服）again and waited．Maya，the dolphin，had been swimming playfully，but suddenly she threw herself to the back of the tank where the filter box（过滤箱）was located．She stuck her nose down behind the box and then swam away．
Hallie followed Maya．"What was she doing here？"she wondered．When she looked behind the box，her question was answered．She swam back and saw Maya was in front of Kathy with a comb in her mouth waiting for her treat．
"Maya!Where did you get that？"demanded Kathy，taking the comb and throwing her a fish．
"I know，"declared Hallie，handing Kathy a handful of items，"I followed her to the filter box and these are what I found．"
From the look on Kathy's face，Hallie knew everything was beginning to come to light．
"Do you remember the other day you said that Maya really liked her treats？"asked Kathy．"Well，I think this was more than a training exercise for Maya．Every time you found something in the tank，that meant one less fish for Maya．She couldn't bring all the items to me at once，so she found a hiding place for them．That way you came up empty-handed，but Maya would always get her treat．"
"Okay，Maya，"said Hallie facing the dolphin，"you win!The treats are all yours．"
Maya dived down，and then jumped out of the water，turning herself over in midair．Shaking their heads in disbelief，Hallie and Kathy reached for the fish．Maya deserved the treat．

21．What was the"mystery"in the story？A
A．The secret of Maya's finding the items．
B．The secret of Hallie's winning the game．
C．The reason for Maya's liking her treats．
D．The reason for Hallie's spying on Maya．
22．Maya hid the items because she considered Hallie as aB．A．spy B．competitor C．playmate D．trainer
23．At the end of the story，Hallie and Kathy thought Maya wasD．
A．energetic B．genuine C．loyal D．smart．

分析本文主要讲述了一只聪明的海豚和2个饲养员之间的故事．

解答 21．A 细节题．根据文章内容，"Don't get discouraged，"Kathy said，comforting her with a hug．"It sounds as if you have a bit of a mystery to solve．Maybe you should do a little spying on Maya．"不要沮丧了，哈利．Kathy一边安慰一边给了哈利一个大大的拥抱．听起来你好像有很多谜团要解决．或许你该精心调查一下 Maya仔细观察一下它．结合选项，故选A
22．B 细节题．根据文章内容，．"Well，I think this was more than a training exercise for Maya．Every time you found something in the tank，that meant one less fish for Maya．She couldn't bring all the items to me at once，so she found a hiding place for them．That way you came up empty-handed，but Maya would always get her treat．"我想这对于Maya而言不仅仅是训练．每一次在水箱里找到东西的时候，那就意味着对于Maya就少了一条鱼．她不能立刻把所有的东西都立即拿给我，因此她找了一个地方把东西藏起来了．每次你空手而归的时候，她还是可以得到她的吃的．由此可知，Maya视哈利为竞争者了，结合选项，故选B
23．D 推理题．根据文章内容，Maya dived down，and then jumped out of the water，turning herself over in midair．Shaking their heads in disbelief，Hallie and Kathy reached for the fish．Maya deserved the treat．由此可知，Maya从水中跳出来，在空中翻转了一下．Hallie and Kathy面对Maya 的行为，他们都觉得她很聪明，让人不可思议．结合选项，故选D

15．In many cases they have built their reputations over hundreds of years，and they have become names that millions of Chinese love，respect and most of all buy．
At least once a year，Meng Wei visits several shops in Beijing that specialize in traditional goods，longing to buy something for his family in Xi'an．
"It's a routine I go through before I head home for big holidays such as the Spring Festival，"Meng says．
His shopping list includes Daoxiangcun pastries and Niulanshan Erguotou．"My mother has a sweet tooth and she always has a preference for Daoxiangcun，and my uncles love the kick of Erguotou，"Meng says．
A trust in quality and a desire for things of the past are among the reasons why many people buy these time-honored brands．
However，with such brands one characteristic stands out above all else：Their popularity has endured for years，decades and in many cases centuries．That popularity was evident in the attention the public gave to them in a survey（调查） of time-honored brands in Beijing last year，which drew more than 4million respondents．
Yili，a century-old pastry brand，came out on top as the favorite．There are some old brands，too，that have been bywords for older generations，faded from view but then made spectacular comebacks．
One of these is Beibingyang （Arctic Ocean） a soft drink that was the first commercial beverage many Beijingers tasted．It disappeared from the market for 15years but resurfaced in 2010．It again proved to be a hit，many people saying it took them back to the 1960s and 1970s，and was a natural reference point as older people started recounting childhood stories to their children．
"Such brands are the product of market competition and real quality，"says Yin Jie，an official with a committee of experts charged with revitalizing Chinese time-honored brands．These brands are 230years old on average，and some were highly popular back when the country enjoyed great prosperity（繁荣） hundreds of years ago，Yin says．"To this day what China contributes to these brands is certain rare natural ingredients（成分），and that keeps them going．"

5．Exhausted，covered in mud and desperately hungry，a team of Swedish athletes sat down for a meal as they prepared to take on a dangerous 20-mile journey through the Ecuadorian rainforest．As they opened their canned meat，a tired member，Mikael Lindnord noticed a miserable lost dog staring at him out of the corner of his eye．
Feeling sorry for him，he fed the dog a meatball and thought nothing of it，but as the team stood up to continue their race，the animal started to follow them and he didn't stop．
As the group of four navigated the final two stages of the 430-mile Adventure Racing World Championship，the dog befriended them and was eventually given the name Arthur．Every tiring task the team face，Arthur would do the same．He swam alongside rivers while they kayaked down them，dragged himself up hills during hikes and pulled through knee-deep mud during journeys．
Even when the team tired to get rid of their new member out of concerns for his safety，he refused to leave．This meant when he was tired，they stopped for a break and when he got stuck in the mud，they pulled him out．
After six days the team finished the race，and the dog had suffered．They therefore decided to take him to a vet．During that time Lindord thought to himself that after their experience，they could not leave Arthur，so he decided to adopt him and take him back to Sweden．He applied to the Jordbruksverket （the Swedish Board of Agriculture） and was made to wait to see if his application was successful．
After a few days，the team arrived at the airport with Arthur and boarded the plane with him back home．Lindord ended by saying："I came to Ecuador to win the World Championship．Instead，I got a new friend．"

12．Imagine the tallest building in the United States．Fill that giant building 44times with rotten fruits and vegetables．Now you know how much food Americans waste every year．
It is hard to believe，right？About 133billion pounds of food get thrown away．That's one-third of all the food we produce．And a lot of it is thrown away for one simple reason：It's ugly．
The problem is that nature isn't perfect．Apples can get scarred（留下疤痕）by storms．Cucumbers grow in C shapes．Carrots change into unusual fork-like forms．Watermelons get too big to fit on a refrigerator shelf．These crazy-looking fruits and vegetables may taste great．But most grocery stores refuse to sell them．Store owners say people judge food by how it looks．No one wants a tomato that looks like a two-headed monster．But what if you could buy that tomato for half-price？
A new movement is trying to make people see the"beauty"in ugly food．Some stores are selling ugly produce．It tastes the same．And you pay less for it because the food doesn't look perfect．
Usually，the stores find a nicer word than"ugly"．A Canadian chain uses"naturally imperfect．In some US stores，it's"misfit produce"．Whatever you call it，ugly food helps many people．Farmers get paid for food they were going to have to throw away．Shoppers get cheaper fruits and vegetables．The ugly-food movement will also help some of the 44million Americans who don't have enough to eat．Many groups give the ugly produce to hungry people．
So really，who cares if that carrot looks a little…ugly？

28．Why are lots of fruits and vegetables thrown away in the US？A
A．Because they don't look nice．
B．Because they have gone bad．
C．Because they don't taste good．
D．Because they are badly polluted．
29．What is the 5th paragraph mainly about？D
A．The stores selling ugly food．
B．The better names for ugly food．
C．The number of hungry Americans．
D．The benefits of the ugly-food movement．
30．What does the mark"…"in the last paragraph suggest？C
A．The author would like to buy ugly carrots．
B．No one would care if a carrot looks a little ugly．
C．The author does not quite like the word"ugly"．
D．Nobody really wants to buy carrots that look ugly．

9．Monty Hempel is a professor of environmental science at Redlands University in California．He studies ecological literacy-or ecoliteracy （生态素养） for short．Ecoliteracy is the ability to think about and understand the natural processes that make life possible．
Monty Hempel says ecoliteracy gives people knowledge about environmental problems．But he says it does not always work to get them to change their behavior．
Mr．Hempel wrote part of the World watch Institute's latest State of the World report．He says in his article，"Some people think that ecoliteracy is just a green form of science literacy．And what I have tried to ask is whether that's enough．In other words，what an ecologically literate person needs to know might include things like the cycles and the flows，the energy systems，all of those kind of things that we would call the science of ecology．"
"That doesn't seem to lead to action to protect our environment-to protect our life-support system to the level that we need to．Just because that we know，a lot about the environment doesn't mean that we actually act to save it．After all，actions speak louder than knowledge．"
He adds that people may not be very worried about environmental problems if they seem far away．"Some people call it psychological distance．A lot of climate issues （问题） are worse in the Arctic and most of us don't spend time in the Arctic．And so，there^a certain distance．But there's also a distance that's happening in the world as it urbanizes （城市化）-people spending more time in front of screens and less time out in nature．We become，if you will，disconnected from the natural systems that used to be the key to success for a human being．"
To help children discover the wonders of nature，children should learn about nature in school，he adds．But he also points out there is a high mountain for people to climb from knowledge to action．

32．From what Monty Hempel says in Paragraph 3，we learn thatA．
A．ecoliteracy is more than a green form of science literacy．
B．people have learnt more knowledge about ecoliteracy．
C．ecoliteracy can greatly affect how nature works．
D．people with enough knowledge will better protect the environment．
33．In Mr．Hempel's opinion，which is the most important for environment protection？B
A．Knowledge．
B．Action．
C．Green living theory．
D．Psychological distance．
34．Mr．Hempel thinks people may show no concern about some environmental problems becauseD．
A．they lack knowledge on environment protection．
B．they are closely connected with the nature．
C．the problems are not serious at all．
D．the problems seem to be far away．
35．What can be inferred from the last paragraph？C
A．It is the best way to learn about nature in school．
B．Climbing a high mountain is a good way to exercise．
C．It is easier to understand environment protection than to carry it out．
D．people should first collect waste in the mountains to protect the environment．

19．Prepackaged，mass-produced snack foods are hugely popular in grocery stores around the world，Many people are accustomed to choosing snack foods in grocery stores．
The first problem with packaged snack foods like cookies，crackers，and other bite-sized options is that they are often loaded with unhealthy materials．The reason for this is fairly easy to understand．Mass-produced foods need to be uniform in color，taste and so on．In order to achieve this uniformity，snack food producers use sugar，salt，and other chemical preservative（防腐剂） and coloring materials in large amounts．These materials contribute to a rather unhealthy food．
In addition to requiring uniformity of taste and appearance，mass-produced snack foods like potato chips and candies need to be shelf stable．Preservatives and complex packaging make products shelf stable，but this stability and non-perish ability（抗腐性） often come at the expense of nutrition．
One reason that pre-made snacks are so popular in grocery stores is their prices．Food producers can keep costs down by using established production facilities and processes to quickly produce a huge amount of food．Shoppers are drawn to what they see at low prices．
People who are interested in improving the quality of their snacking can use magazines，books，and the Internet to discover a lot of healthy snacking tips and ideas．Even television shows about health and food sometimes talk about healthy snacking alternatives．Some healthy snacks，like fresh fruit，require no preparation at all．
Once people are aware of the drawbacks of clearly cheap and easy snack foods，they can start turning to better options．Soon，perhaps，the old and unhealthy snack options will no longer be profitable for food producers．
