All the World Asks
On my first day in a college classroom, I felt like an overgrown child returning to civilization after having been lost in the forest for thirty years. There I sat,  21  enough to be a father to most of the students in the room,   22   unconfident enough to be their baby brother. We were crowded elbow (肘部) to elbow, listening to a  23  who looked even younger than the students. I felt uncomfortable and out of place as the professor carefully    24  what she expected us to learn. As I listened, I couldn't help but  25  of my own oldest daughter who was now beginning her first year in    26  , just like me. I remembered how hard I had tried to help build self-confidence in her and my other children. So why did I suddenly feel like a scared   27  myself'? When I walked out of that classroom, I had serious    28   about my ability to make it   29  college. Not until late that night did my thinking   30    .It was a long-distance  31   from my daughter, my fellow college freshman, that did the trick. She spoke on the phone about the doubts, worries and anxieties she was   32 . She was certain that she'd never   33  at college. How   34   her worries sounded! In my most confident parental   35  , I said, “Doing your best is all the world   36  .” The next day in class, those words still repeated in my head. When the professor raised a   37   for the class, nobody, including me,    38  to answer. When I looked around al the   39   and uncertainty on the young faces in that room, I knew   40  what I had to do: my best. That's all the world asks. So I raised my hand, and the professor called my name. I spoke.

How Much to Tip
You’re out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.
Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words, to how they carry themselves while taking orders, to the bill’s total. Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.
“Studies before have shown that mimicry (模仿) brings into positive feelings for the mimicker,” wrote Rick van Baaren, a social psychology professor. “These studies show that people who are being mimicked become more generous toward the person who mimics them.”
So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such as, “Coming up!” Those in the other half were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their take-home. The results were clear — it pays to mimic your customer. The copycat(模仿者) waiters earned almost double the amount of tips to the other group.
Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity of a tipper may be limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists, they found tip percentages in these three areas dropped as customers’ bills went up. In fact, tip percentages appear to plateau (達到穩定水平) when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a bill for $100.
“That’s also a point of tipping,” Green says. “You have to give a little extra to the cab driver for being there to pick you up and something to the waiter for being there to serve you. If they weren’t there, you’d never get any service. So part of the idea of a tip is for just being there.”
【小題1】 Apart from service, how many other factors affecting the customers’ tipping are mentioned in the passage?

A.1.B.2.C.3.D.4.
【小題2】 These studies show that _________.
A.tipping can be affected by physical reactions to many different waiter’s factors
B.people who are being mimicked usually tip less to the person who mimics them
C.the mimic waiters can get almost twice as much money as the other group
D.mimicry makes the mimicker feel bad
【小題3】 According to the passage, which of the following will be likely to show the right change of the tip percentages?
 
A                    B                  C                  D
【小題4】 We know from the passage that the writer seems to __________.
A.object to Mr. Green’s idea about tipping
B.think part of Mr. Green’s explanation is reasonable
C.give his generous tip to waiters very often
D.support the opinions of Mr. Green and Rick van Baaren about tipping

"I've changed my mind.I wanted to have a telescope, but now I want my daddy back." Lucien Lawrence's letter to Father Christmas, written after his schoolteacher father had been knifed to death outside his school gale, must have touched every heart.Lucien went on to say that without his father he couldn't see the stars in the sky.When those whom we love depart from us, we cannot see the stare for a while.
But Lucien, the stars are still there, and one day, when you are older and your tears have gone, you will see them again.And, in a strange way, I expect that you will find your father is there too, in your mind and in your heart.I find that my parents, long dead now, still figure in many of my dreams and that I think of them perhaps more than 1 ever did when they were alive.I still live to please them and I'm still surprised by their reactions.I remember that when I became a professor,! was so proud, or rather so pleased with myself, that I couldn't wait to call my parents.The reply was a long time in coming, but when it did, all Mother said was "I hope this means that now you will have more time for the children!" I haven't forgotten.The values of my parents still live on.
It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care.Would I have been as ready as Philip Lawrence have been to face the aggressors (挑釁者), and to lay down my life for those in my care? How many people would want me back for Christmas'' It's a serious thought, one to give me pause.
I pray silently, sometimes, in the dead of night, that ancient cry of a poet " Deliver my soul from the sword(劍), and my darling from the power of the dog." Yet I know the death comes to us all,
and sometimes comes suddenly.We must therefore plan to live forever, but live as if we will die
tomorrow.We live on, I'm sure, in the lives of those we loved.and therefore we ought to have a care
for what they will remember and what they will treasure.If more parents knew this in their hearts to
be true, there might be fewer knives on our streets today.

科目:高中英語 來源:2013屆天津市高考壓軸卷英語卷(帶解析) 題型:閱讀理解

“Confidence” is probably one of the most noticeable traits(品質)in the Americans. They show confidence in the way they talk, the way they smile, the way they dress and the way they walk. Living and competing with all these confidence American students, I find it extremely important to be confident as an international student and instructor. As a student, being confident means you should never hesitate to raise your hand whenever a question or a point comes to your mind. Don’t mind if it sounds simple or silly. Otherwise you will never get a chance to speak in class at all. What’s worse, the professors may think you are not prepared for the discussion or you do not have your own opinion on the issue-this is the last comment any graduate would like to receive。  
Being confidence for me as a foreign instructor means calmly asking the student to repeat what he or she has said if I did not get it. Pretending to understand what you actually did not may just bring yourself embarrassment or even disgrace. But the time I most need to be confident is when my students come to my office and bargain about the grades I have given for their Speeches。(The course I’m teaching here is Public Speaking). Modesty is a trait highly valued in China, but it won’t be of much help here if you want to survive and succeed in a good American graduate program.
【小題1】To compete with American students it’s very important to

A.be quite confident
B.be polite and friendly
C.have more discussions with
D.understand what they think about
【小題2】A professor will have the worst opinion of a student who
A.gives a silly or simple answer
B.tries to seize any chance to speak in class
C.shows no interest in the course
D.is considered to have no opinion of his own
【小題3】The author is most likely to feel embarrassed if
A.he asks a student to repeat what he has said
B.the students bargain with him
C.he pretends to know what he doesn’t
D.he has to give a speech
【小題4】We learn from the second paragraph that
A.we should also remain modest in America
B.modesty doesn’t help modest in America
C.American also like modest people
D.modesty can help you through an American graduate program
【小題5】What can we infer from the passage?
A.American students are ready to accept the grades from the teacher.
B.The writer teaches in Europe for a living.
C.Students are encouraged to present simple questions.
D.One’s ignorance will give away in time.

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can' t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain' s temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
【小題1】The biggest difficulty in operating on the damaged brain is that _______.

A.the time is too short for doctors
B.the patients are often too nervous
C.the damage is extremely hard to fix
D.the blood-cooling machine might break down
【小題2】The brain operation was made possible mainly by _______.
A.taking the blood out of the brain
B.trying the operation on monkeys first
C.having the blood go through a machine
D.lowering the brain' s temperature
【小題3】With Dr. White' s new idea, the operation on the damaged brain _______.
A.can last as long as 30 minutesB.can keep the brain' s blood warm
C.can keep the patient' s brain healthyD.can help monkeys do different jobs
【小題4】What is the right order of the steps in the operation?
a. send the cooled blood back to the brain
b. stop the blood to the brain
c. have the blood cooled down
d. operate on the brain
A.a,b,c,dB.c,a,b,dC.c, b, d, aD.b, c, d, a
