When his pole 28 , he knew something huge was 29 . His father watched 30 as the boy skillfully worked the fish alongside the dock. Finally, he very carefully lifted the 31 fish from the water. It was the largest one he had ever seen, 32 it was a bass. It was 10 p.m. — two hours before the season opened. The father looked at the fish, then at the boy.
“You’ll have to 33 , son,” he said.

A
While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.
The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to complete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.
I watched the man dive off the block and knew right away that something was wrong. I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold—his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.
I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.
But in those few awful strokes, the crowd had changed.
No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it！” and he did.
A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and he should have. Even though he recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.
Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.
In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog.
46．From the passage we can learn that the young man ______.
A．made his turn to start back pitifully
B．was skillful in freestyle in the game
C．swam faster than the average swimmer
D．was not capable enough to win the medal
47．The crowd changed their attitudes because ________.
A．they felt sorry for the young man
B．they were moved by the young man
C．they wanted to show their sympathy
D．they meant to please the young man
48．According to the passage, “it is nice to watch an underdog” probably means ________.
A．it's amusing to watch a man with awful swimming skills
B．it's amazing to watch an ordinary man challenging himself
C．it's cheerful for athletes to act proudly before their competitors
D．it's brave enough for some athletes to remove the silver medals
B
Some years ago, I was hired by an American bank. I received a letter from the head of the Personnel Department that started, “Dear John, I am quite pleased that you have decided to join us.” That “quite” saddened me. I thought he was saying “we’re kind of pleased you decided to join us although I wish we had hired someone else.” Then I discovered that in American English “quite” sometimes means “very”, while in British English it means “fairly”.
So the first lesson about working in other countries is to learn the language and by that I don’t just mean the words people speak. It is the body language, dress, manners, ideas and so on. The way people do things highlights many of the differences we see between cultures.
Some of these differences may be only on the surface—dress, food and hours of work—while others may be deeper and take longer to deal with. Mostly, it is just a question of getting used to the differences and accepting them, like the climate, while getting on with business.
Some of the differences may be an improvement. People are more polite; the service is better; you ask for something to be done and it happens without having to ask again. However, other differences can be troubling, like punctuality(准时). If you invite people to a party at 7 o’clock your guests will consider it polite to turn up exactly on time in Germany, five minutes early in the American Midwest, an hour early in Japan, 15 minutes afterwards in the UK, up to an hour afterwards in Italy and some time in the evening in Greece. I prefer not to use the word “late” because there is nothing wrong with the times people arrive. It is simply the accepted thing to do in their own country.
49. The author was unhappy as mentioned in Paragraph 1 because he thought________.
A. the American bank didn’t think much of him
B. the American bank might hire another person
C. it’s difficult to get used to American culture
D. it’s easy to misunderstand Americans
50. The word “highlight” in Paragraph 2 probably means____________.
A. encourages B. helps to narrow C. increases D. draws attention to
51. According to the author, what should we do with most cultural differences?
A. Ask the native people for help
B. Understand and accept them
C. Do things in your own way
D. Do in-depth research
52. When invited to a party the people who are usually punctual are__________.
A. Italians B. Germans C. Greeks D. The British
C
Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases with his students . The case at hand was a Guatemalan man , aged 34 , who had a fever and many other medical problems . His condition was not improving , and there was not much hope he would live .
Dr. Mellinkoff asked to see the patient . He introduced himself in Spanish and , in a very gentle voice , asked how he felt . The patient smiled and said everything was all right . Then the doctor asked if he was able to eat . The patient said that he had no desire to eat .
“ Are you getting food you like ? ”
The patient said nothing .
“ Do you get the kind of food you have at home ? ”
The answer was no .
The doctor put his hand on the man’s shoulder and his voice was very soft .
“ If , you had food that you liked , would you eat it ? ”
“ Yes , yes . ” the patient said .
The change in the patient’s appearance couldn’t have been more obvious . Nothing was said , but it was easy to tell that a message had been sent and had also been received .
Later , the doctor asked why the Guatemalan man wasn’t getting food he could eat . One of the students said , “ We all know how difficult it is to get the kitchen to make special meals . ”
“ Suppose , ” the doctor replied , “ you felt a certain medicine was absolutely necessary but that our hospital didn’t carry it , would you accept defeat or would you insist the hospital meet your request ? ”
“ I would probably insist , ” the student said .
“ Very well , ” the doctor said . “ You might want to try the same method in the kitchen . It won’t be easy , but I can help you . Meanwhile , let’s get some food inside this man as fast as possible , and stay with it . Or he’ll be killed by hunger . By the way , there must be someone among you who can speak Spanish . If we want to make real progress , we need to be able to talk with him . ”
Three weeks later , Dr. Mellinkoff told me that the Guatemalan man had left the hospital under his own power . It takes more than medicine to help sick people ; you also have to talk to them and make them comfortable .
53. The patient had no desire to eat because __________ .
A. he was not hungry B. he was seriously ill
C. he was given special meals D. he was not satisfied with the food
54. According to the passage , we can conclude that __________ .
A. the patient was from another country .
B. the patient’s illness was caused by hunger
C. Dr. Mellinkoff performed an operation on the patient
D. the hospital failed to provide the right medicine for the patient
55. Which of the following words can be used to describe Dr. Mellinkoff ?
A. Cold . B. Considerate . C. Curious . D. Confident .
56. What do you think Dr. Mellinkoff wanted to tell his students in this case ?
A. Doctors should be able to speak foreign languages .
B. Doctors should know their patients’ real problems .
C. Doctors should try to improve their medical skills .
D. Doctors should give more medicine to patients .

If your child has gone from a continuous chatterbox to making conversations that consist mostly of yes and no, it’s time to consider these tips on how to talk to kids, so you’ll know what’s going on in your child’s world.
61.
The quickest way to get kids to shut up and, as a result, shut you out of their lives is to continuously press them about things. A more effective way is to sit back and patiently wait for them to open up in a low-stress family and then be prepared to listen.
62.
Parents can sometimes make kids at a young age decide it is best not to talk about something when they are criticized. If you really want to know what’s on your child’s mind, then avoid passing judgment and focus instead on why something seems important to your child.
63.
If you want to raise a creative and independent thinker, stop telling your child what he ought to feel or think. You can gently encourage additional conversations by simply asking why he feels the way he does or what he would do in a certain situation.
64.
You may think you’re just asking questions out of curiosity when communicating with your child, but an endless stream of questions about what they did, whether everyone got along, if they went to the bathroom, etc., are enough to make anyone shut up! Practice patience and let your kids open up on their terms.
65.
Kids can relate to you and other adults when you tell your stories happening when you were their age. Talking to kids by telling them about things like something embarrassing that happened or the first crush (迷恋) you had helps them to connect with you and understand that you might actually know what they are going through!
