Some talked of jobs they already had，others of jobs they would get. With four years of college study，they felt ready and able to conquer(征服)the world.
The coming exam，they knew，would be easy. The professor(教授)had said they could bring any books or notes they wanted，but they couldn’t talk to each other during the test.
They walked into the classroom. The professor passed out the papers. The students’ smiles became wide as they saw that there were only five essay-type questions.
Three
hours passed and the exam came to an end. Then the professor began to collect the papers. The students no longer looked confident. They seemed worried. No one spoke as the professor faced the class with the papers in her hand.She looked at all the worried faces in front of her, and then asked，“How many students completed all five questions?”
Not a hand was put up.
‘‘How many of you answered four?” Still no hands.
“Three?Two?”The students moved restlessly in their seats.
“One，then. Certainly somebody finished one．”But the class stayed silent. The professor put down the papers.“That is just what I expected，”she said.
“I just wanted to make sure you realize that even though you have studied engineering for four years, there are still many things about the subject you don’t know. Instead of testing you on what you learned in this class, I’ve given you questions that skilled engineers face in the world outside the classroom. You can’t expect to be an expert(专家)on the day you graduate. You have to learn as you go.”
Then，smiling, she added，“You will all pass this course, but remember that your education has just begun.’’
小题1:What does the underlined word“restlessly”mean in the passage?
| A．confidentIy | B．proudly | C．excitedly | D．nervously |
| A．To make the students realize that they still had much to learn after graduation. |
| B．To find out whether the students could put what they had learned into practice. |
| C．To show that she had much more knowledge than her students in engineering. |
| D．To examine whether the students learned what they had been taught in her class. |

An apple a day may keep aging away.
The research chose fruit flies(果蝇), as they share many genes(基因)with humans. The fruit flies were either fed normally or had an apple extract(浓缩物) added to their diet.
It turned out that those fruit flies that were given apple extract lived about 55 days—five days longer than the flies that were normally fed. The research group also found it easier for the flies to walk，climb and move about as they aged.
According to the result, the researchers believed that the antioxidants(抗氧化剂) in the apple extract helped clean up dangerous chemicals(化学物质) that cause illnesses，as well as aging.
In another study，researchers examined diets of thousands of women. They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke.
The apples’ genetic code(遗传密码) was discovered recently. It allows scientists to develop nicer and healthier fruits. Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer.
Apples that kill the desire(***) to eat could also be produced, with the first“extra-healthy’’apples on supermarket shelves within just four or five years.
T
he team that keeps studying apple DNA includes 100 scientists from five countries. Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant，which would finally become today’s apple tree, experienced a great genetic change. The number of many of its genes doubled. The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches，strawberries and other related fruits.小题1:Why were fruit flies used for the research?
| A．Because they have a similar diet to humans. |
| B．Because they have a history as long as apples. |
| C．Because they share a lot of genes with humans. |
| D．Because they feed on nothing but apple extract. |
A．Apples produce chemicals that can change hu man genes. |
| B．Apples have antioxidants that kill chemicals that cause aging. |
| C．Apples are rich in vitamins that are needed in humans’bodies. |
| D．Apples produce chemicals that make apples taste more delicious. |
| A．Their genes stopped their development as the environment got worse. |
| B．Their genes became twice in number but they finally died off like dinosaurs. |
| C．They experienced a great genetic change making them used to worse conditions. |
| D．They went through a similar development to peaches, strawberries and other related fruits. |
| A．Eating apples may bring us more advantages than we might believe before. |
| B．People who have the habit of eating apples don’t need to see a doctor. |
| C．Apples that kill the desire to eat are already available in supermarkets now. |
| D．People will eat apples instead of peaches and strawberries from now on. |
pick Dad up at 4 pm. Because I had a few hours to spend, I decided to go to the 38 .However I became 39 interested in the film that I forgot the time. When the last film finished,
it was 6 o’clock. I was afraid Dad would be 40 and never let me drive again, so I drove back quickly to meet Dad and made an excuse(借口) 41 my being late. I’ll never forget the cry he gave me: “I’m disappointed that I feel you have to tell a lie to me, Jack. I’m angry, not with 42 but with myself. I have failed 43 I’ve brought up a son who can not even tell the truth to his own father. I’m going to walk home now and think seriously about 44 I have done wrong all these years.”
Dad began 45 along the road. I begged(乞求)all the way, telling him how I drove behind him for 40 miles, at a speed of 5 miles an hour. It was the most unforgettable lesson. I have never told a lie to him ever since.

A minute passed, and another, 48 the teacher didn"t appear. We began to wonder what was the matter with her. Was she ill? Or had she forgotten about the class? 49 could tell. Soon some students began to study other subjects, some students began to talk and even made 50 .
About ten minutes later, the door opened and Miss Liu 51 came in, smiling. She didn"t say sorry to the class. We felt 52 angry. The teacher often told us never to be late for class and said it was 53 manners to be late. She also said that if we were late, we should make an apology (道歉) 54 at once or after class. But now she was late and had kept the whole class waiting for such a long time and didn"t even tell us the reason. It was unfair. At this moment, Miss Liu picked up a piece of chalk(粉笔) and 55 "T
