7．Learning is a continuous process of life．We all learn from（36）Dthings in life．One of the things that（37）Ame recently is what I learned from turtles（海龟）．
Turtles could teach a vast number of people a lot about reaching goals．（38）C，have you ever watched a turtle making its way to a stream？The turtle（39）Bwhere it is going； in other words，it has set a goal．Many people（40）Ago through life with no specific goal in mind．They seem to weave back and forth because their life direction seems to（41）Din relation to whatever influences them at that time．
Turtles，on the other hand，have a goal in mind easily（42）Cif you take time to watch them．The turtle has only one（43）B．No matter how long it（44）Athem，they will do everything they can to reach their goal．
    （45）D，the turtle may be slow．（46）Cthe turtle keeps going．Each step they take，no matter how small，they keep taking it（47）Bto their destination．The turtle never（48）Ca step or breaks into a run．The reason is that turtles have a better sense of the（49）A of  taking small steps over and over again to reach the final victory．

4．Throughout the world，clothing has many uses．It is used to provide protection from cold．It is also worn to prevent others from seeing specific parts of one's body．However，the parts of the body that must be covered vary widely throughout the world．Some clothing is worn to provide supernatural protection．Wearing a lucky shirt to take an exam is calling for supernatural assistance．
People in all cultures use clothing and other forms of bodily decoration to communicate status（身份），intentions and other messages．In North America，we dress differently for business and various leisure activities．North American women usually are much more knowledgeable of little difference in messages communicated by clothes than men．At times，this leads to silly mistakes of understanding of female intentions on the part of men．Of course，clothing styles also are intended to communicate messages to members of the same gender（性别）．
Long before we are near enough to talk to someone，their appearance tells their gender，age，economic class，and often even intentions．We begin to recognize the important cultural clues at an early age．The vocabulary of dress that we learn includes not only items of clothing but also hairstyles，jewelry，and other body decoration．In most cultures，however，the same style of dress communicates different messages depending on the age，gender，and physical appearance of the individual wearing it．
Putting on certain types of clothing can change your behavior and the behavior of others towards you．This can be the case with a doctor's white lab coat，or an army uniform．Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status．For instance，the strange hairstyle and clothing of the English"punks"are essential aspects of their uniforms．
There are many forms of body decoration other than clothes that are used around the world to send messages．These include body and hair paint，and even body deformation．When doctors put braces on teeth，they are actually doing the same thing-deforming or reforming a part of the body to make it more attractive．

A．Clothing and Culture
B．Ways of Sending Message

A．clothes can hide t heir fear for the exam
B．clothes have extraordinary power
C．shirts can make them more comfortable

A．clothing plays an important role in social activities
B．words of dress are unable to communicate different messages
C．dress is better than language in communicating messages
D．messages communicated by clothes are the same in different cultures．
11．Tayka Hotel de Sal
Where：Tahua，Bolivia
How much：about﹩95a night
Why it's cool：You've stayed at hotels made of brick or wood，but salt？That's something few can claim．Tayka Hotel de Sal is made totally of salt-including the beds （though you'll sleep on regular mattresses and blankets）．The hotel sits on the Salar de Uyuni，a prehistoric driedup lake that's the world's biggest salt flat．Builders use the salt from the 4，633squaremile flat to make the bricks，and glue them together with a paste of wet salt that hardens when it dries．When rain starts to dissolve the hotel，the owners just mix up more salt paste to strengthen the bricks．
Green Magic Nature Resort
Where：Vythiri，India
How much：about﹩240a night
Why it's cool：Riding a pulleyoperated（滑轮操控的） lift 86feet to your treetop room is just the start of your adventure．As you look out of your open window-there is no glass-you watch monkeys and birds in the rain forest canopy．Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel．You don't even have to come down for breakfast-the hotel will send it up on the pulleydrawn"elevator"．
Dog Bark Park Inn B&B
Where：Cottonwood，Idaho
How much：﹩92a night

1．（36）E
Britain may be the most red-headed country in the world．About 1to 2percent of the world's population has red hair，but in the UK the numbers are much higher，with 13percent of Scots，10percent of the Irish，and 6percent of people in England having red hair，according to the BBC．
（37）G
Scientists have tried to explain why some people have red hair for some time and now they may have found an answer：the dull weather in Britain．The human body needs vitamin D from sunshine，but unfortunately people living in Britain do not have enough of it because of its maritime climate．In fact，Britain gets even more cloud than countries in the far north of Europe．In Sweden，for example，the average daily hours of sunshine is 5.4．In Scotland it is only 3.1hours．
（38）D
To deal with this，the DNA of people living in these areas has changed slightly； scientists call this a mutation．Originally，the coloring on our body is a mixture of two kinds of melanin-black melanin is suppressed while only red/yellow melanin is made．The result is red hair，light skin color，freckles and a greater sensitivity to sunlight．
（39）C
However，what's more interesting is that the redhead DNA mutation is recessive，which means it is hidden and can often skip generations without showing．At least 1.6million Scots carry a redhead gene mutation，and most are unaware that they do．This is why a person who does not have red hair can still produce red-haired children if he or she is a carrier of this special DNA．
（40）B
The research on red hair，like many areas of science，is contradictory（不一致）．In 2002researchers showed that redheads are more sensitive to pain，and need more anesthetic during surgery than people with blonde or dark hair．However，in 2005scientists found that a MCRIR mutation gives redheads a higher tolerance for pain．Research into these aspects of red hair genetics continues．Redheads should though be more careful about their exposure to sunlight as they are at an increased risk of contracting skin cancer．If you are a redhead，the advice is not to stay out of the sun，but to be careful about how much exposure you get，and to cover yourself with a high factor sunscreen．

A．Redheads'benefits
B．Divided opinions
C．Inheriting（遗传） characteristics
D．Gene mutation（基因变异）
E．Home of the redheads
F．Various weather types
G．Weather is to blame．
8．Teachers say the digital age has had a good influence-and a not-so-good influence-on this generation of American teenagers．More than 2，000teachers took an online survey．Three-quarters of the teachers said the Internet and digital search tools have had a"mostly positive"effect on their students'research habits and skills．But 64percent said the technologies"do more to distract （使…分心） students than to help them academically．"And 87percent agreed that these technologies are creating an"easily distracted generation with short attention spans．"
The Pew Internet Project did the survey with the National Writing Project．Judy Buchanan is the vice director of the National Writing Project and a co-author of the report．Ms．Buchanan says digital research tools are helping students learn more and faster．"Teachers really favor these tools because they are ways to make some of the learning exciting and engaging．Young people favor these tools．The goal is to really help them become creators of meaningful content，and not just sort of consumers．"
But one problem the survey found is that many students lack digital literacy．They trust too much of the information they find on the Internet．Judy says these students haven't developed the skills to determine the quality of online information．"It's something that really has to be taught and paid attention to．Because in a world in which things happen quickly，you do need to step back，reflect and analyze the information you have．"
Another problem is blamed on something that might not seem like a problem at all：being able to quickly find information online．Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers．They say students are overly dependent on search engines and do not make enough use of printed books or research libraries．
Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities．

28．The text mainly tells usC．
A．all the students use digital tools        
B．the Internet is playing a key role
C．digital tools bring about benefits and problems
D．teachers encourage using digital tools
29．Which of the following best shows the structure of the text？A

30．The underlined sentence in the third paragraph probably meansB．
A．students do not have the right digital tools
B．students can't judge online information properly
C．students haven't the ability to adjust themselves
D．students do not always have access to the Internet
31．Some students don't tend to work hard becauseD．
A．they can copy each others'work without being punished
B．printed books and libraries around aren't enough
C．the Internet can't make students concentrate
D．they can get answers on the Internet quickly．
5．Proverbs are quite common in spoken English．We don't normally put them in a composition or a letter．Sometimes it is helpful if you know what common proverbs mean．Here are a few examples．
1）"Once bitten，twice shy．"If a dog bites me，I shall be twice as careful in future when I see it．This proverb is also used to apply to many things and not only to dogs．If you have been cheated at a shop，you will not go to the same shop again．
2）"A bird in the hand is worth two in the bush．"If I am a hunter，trying to catch birds，it is better to catch one than to see two birds in a bush but not able to catch them．Thus this means that what you have already got is better than the chance of being able to get something bigger in future．
3）"Too many cooks spoil the broth （soup）"．When too many people do something，they get in each other's way and do a bad job．
4）"To pour oil on troubled waters"is to try to calm things down．Oil is lighter than water．If a ship is in trouble at sea，another ship may come to help it．The second ship can send small boats to rescue people．However，it may first pour oil on the sea to make the sea less rough．
5）"Don't be a dog in a manger（槽）"means"Don't be selfish．"In a stable （马房），the manger is the place where the horse's food is put．Sometimes a dog will sleep in the manger and bark when a horse comes to get its food．The dog does not want to eat the hay in the manger but it will not let the horse eat it．
6）"He is sitting on the fence"means that somebody will not say whether he is in favor of a plan or against it．He is sitting on a fence between two opposing sides，perhaps waiting to see which side will win．
7）"He who pays the piper calls the tune．"A piper is a musician．The man who employs or pays a musician can say what tunes the musician will play．Thus this means that if a man provides the money for a plan，he can say how it will be carried out．
8）"You can't get blood out of a stone"means that you cannot get something from a person who has not got any of the things you want．e．g．you cannot get a million dollars from a poor man．
25．Peter has a bicycle which is much too small for him but he does not want to let his younger brother ride on it．His mother is angry and says to him：B．
A．You can't get blood out of a stone      
B．Don't be a dog in a manger
C．Once bitten，twice shy．
D．To pour oil on troubled waters

A．he was sitting on the fence            
B．once bitten，twice shy
C．he who pays the piper calls the tune   
D．a bird in the hand is worth two in the bush
27．Mrs．Lin wanted to buy a new dress．Her husband suggested that she buy it from a shop near their home．Mrs．Lin disagreed because she had been cheated by that shop．So she said："I won't go there again becauseC．"
A．a bird in the hand is worth two in the bush    
B．I am sitting on the fence
C．once bitten，twice shy                     
D．too many cooks spoil the broth

A．a bird in the hand is worth two in the bush  
B．too many cooks spoil the broth
C．you cannot get blood out of a stone         
D．he who pays the piper calls the tune．
