15．Birds Can"Read"Human Gaze
We all know that people sometimes change their behavior when someone is looking their way．Now，a new study reported online on April 2nd in Current Biology shows that jackdaws-birds related to crows with eyes that appear similar to human eyes-can do the same．
"Jackdaws seem to recognize the eye's role in visual perception，or at the very least they are extremely sensitive to the way that human eyes are oriented（朝向），"said Auguste von Bayern，formerly of the University of Cambridge and now at the University of Oxford．
When presented with a preferred food，hand-raised jackdaws took significantly longer to get the reward when a person was directing his eyes towards the food than when he was looking away，according to the research team led by Nathan Emery of the University of Cambridge and Queen Mary University of London．The birds hesitated only when the person was unfamiliar and thus potentially threatening．
In addition，the birds were able to interpret human communicative gestures，such as gaze alternation and pointing，to help them find hidden food，they found．The birds were unsuccessful in using unmoving cues，including eye gaze or head orientation．
Unlike most birds，jackdaws'eyes have a dark pupil surrounded by a silvery white iris．The researchers said they believe jackdaws are probably sensitive to human eyes because，as in humans，eyes are an important means of communication for them．The hand-raised birds examined in the study may be even better than wild jackdaws at attending to human gaze and responding to the gestures of the people who have raised them．
The findings are particularly notable given that most other species investigated so far，including our closest relatives the chimpanzee and"man's best friend，"the dog，are not particularly sensitive to eye orientation and eye gaze，von Bayern said．Rather，she continued，chimps and dogs seem to rely on other cues such as head or body orientation in determining the looking direction of others．The results suggest that birds may deserve more respect for their mental abilities．
"We may have understated the psychological world of birds，"von Bayern said．"Jackdaws，among many other birds，form pair ties for life and need to have much in common and work together with their partner，which requires an efficient way of communicating and sensitivity to their partner's viewpoint．"

67．A hand-raised jackdaw hesitates to take a preferred food when the feederD．
A．is looking away from the food
B．holds the food in his hand
C．is looking at the food
D．is unfamiliar to the bird
68．According to the researchers，jackdaws can notice human eye orientation probably becauseA．
A．like humans，they also use eyes to communicate
B．they are far more intelligent than other birds
C．they are mostly hand-raised by humans
D．their eyes also have a dark pupil
69．Why does the author refer to chimpanzees and dogs？B
A．To suggest that they are much better at interpreting gaze alternation．
B．To reflect how unique jackdaws are in being able to notice gaze orientation．
C．To show that they communicate more frequently with humans than jackdaws．
D．To make clear that they rely on other means in determining people's intention．
70．What does the research finding uggest？B
A．Not all jackdaws are good at attending to human gaze．
B．We may have understated jackdaws'mental abilities．
C．We know embarrassingly less about birds than we assume．
D．The closer we communicate with animals，the better we understand them．

9．My favorite English teacher could draw humor out of the driest material．It wasn't forced on us either．He took Samuel Johnson's dictionary，Addison's essays，and many other literary wonders from the eighteenth century and made them hilarious，even at eight o'clock in the morning．The thing that amazed me most was that the first time I read these works on my own some of them seemed dead，but the second time，after his explanation，I couldn't believe that I hadn't seen the humor．The stories and poems and plays were suddenly filled with allusions （典故） and irony （反讽） and hilarious moments．I learned more from him than from any other teacher．
My least favorite English teacher also made people laugh．Some students found him to be funny．Many others did not．He assigned journals over a six week period，to be written every day．At the end of the six weeks I had a notebook full of bits and pieces about my ideas，short stories，reactions to what we had read，and so on．Our teacher announced that we would be grading each other's journals．Mine was passed to Joe，that class clown，who always behaved in a funny or silly way．He saw it fit to make joke of and said，"This writing isn't fit to line （衬垫） the bottom of a birdcage．"Our teacher laughed at that funny remark．It hurt me so much that the anger from it has driven my writing and teaching ever since．
So what makes the difference？Humor is one of the most powerful tools teachers or writers have．It can build up students and classes and make them excited about literature and writing，or it can tear them apart．It is true that humor is either productive or counter-productive and self-defeating．

56．The passage mainly discussesC．
A．teaching         B．literature
C．humor            D．knowledge
57．The underlined word"hilarious"in Paragraph 1probably meansA．
A．funny            B．tiring
C．inspiring         D．brilliant
58．The English teacher the writer disliked mostB．
A．was not able to make students laugh
B．hurt his students'feelings
C．didn't let his students do the grading
D．had no sense of humor．

16．Hi，Nancy！Thank you for writing to me．I enjoy getting letters from students in China and I'll be happy to exchange letters with you．
The first thing I want to tell you is that if the boys are calling you names it is their fault，not yours．Boys，at your age，are different from girls．They are trying to prove that they are manly and they often do this by choosing someone who can't really fight back．This is，of course，wrong but it happens and it is generally referred to as bullying．In general，the boys know they are bigger and stronger than you are，so they can make fun of you and make you cry and then laugh about it．If you let them see that they are hurting you，they will only do it more．It isn't that they want to hurt you； they simply want to make themselves feel superior．It's stupid but it is very common．
The best way of getting the boys to stop calling you names is to simply ignore them，knowing that the names can't hurt you and that the boys are being stupid．If you can laugh at them，they will get tired of trying to make you cry．Then they will give up and begin to notice you as a young woman．I suspect some of them actually like you and are laughing at you just to get your attention．Again，it's stupid but it happens．In reality，you can control this situation by not letting them see you getting hurt．Laugh at them，tell them they are acting like children and they should grow up and then walk away with your head held high．
One more thing，Nancy．It is very important that you stop hurting yourself．If someone else hurts you it is bad enough but you shouldn't make it worse by then hurting yourself．Even sticking a pen into your finger can cause an infection and give you a lot of trouble and besides，it hurts．The next time you are frustrated by a bunch of stupid boys，write to me．You and I can talk about anything you like，about China，about Canada，about travel，anything．Having a conversation with me is better than sticking holes in your fingers，as least I hope it is．
I wish you all the best and I hope to hear from you again soon．If you get a chance，please send me your picture．
Best wishes．
Brad

13．Dear Dad，
Today I was at the shopping mall and I spent a lot of time reading the Father's Day cards．They all had a special message that in some way or another reflected how I feel about you．Yet as I selected and read，it occurred to me that not a single card said what I really want to say to you．
You'll soon be 84 years old，Dad，and you and I will have had 55 Father's Days together．I haven't always been with you on Father's Day but I've always been with you in my heart．
You know，Dad，there was a time when we were separated by the generation gap．You stood on one side of the Great Divide and I on the other．
The Father-Daughter Duel shifted into high gear（档位）when you taught me to drive the old Dodge and I decided I would drive the 54 Chevy（雪佛兰） whether you liked it or not．The police officer who sent me home after you reported the Chevy stolen didn't have much tolerance（容忍） for a stubborn 16-year-old girl，while you were so tolerant about it，Dad，and I think that was probably what made it the worst night of my life．
Our relationship picked up when I married a man you liked，and things really turned around when we began making babies．Somewhere along the line，the generation gap disappeared．I suppose I saw us and our relationship as aging together，rather like a fine wine．
But the strangest thing happened last week．I was at a stop sign and I watched as you turned the corner in your car．It didn't immediately occur to me that it was you because the man driving looked so elderly and weak behind the wheel of that huge car．It was rather like a slap（打） in the face delivered from out of nowhere．Perhaps I saw your age for the first time that day．
I guess what I'm trying to say，Dad，is what every son and daughter wants to say to their Dad today．Honoring a father on Father's Day is about respect and sharing and acceptance and tolerance and giving and taking．It's about loving someone more than words can say，and it's my wish that it never had to end．
I love you，Dad．
Love，
