Louis Pasteur, the famous French chemist and bacteriologist(微生物學(xué)家), invented “pasteurization”. In 1854 Pasteur was made head of the department of science at the University of Lille, and it was there that he made one of his most famous discoveries. Lille was a major center for wine and beer-making, and some of the local wine-makers asked Pasteur if he could help solve the problem of keeping wine fresh. At that time, it was believed that food and drinks go “bad” due to a purely chemical process. But during a series of experiments Pasteur proved that tiny living organisms(微生物)caused food and drinks to go bad. In the case of wine and beer the organisms are already present in the form of the various yeasts (酵母) that caused the fermentation(發(fā)酵) process. Pasteur discovered that heating the wine gently for a few minutes after it had fermented would kill off the yeast that was left in the wine, with the result that the wine would remain fresh for much longer. He also proved that food and drinks could be turned bad by other organisms that were present in the air, and that they too would keep fresh much longer if they were kept in airtight containers.
The heating process was so successful that it made Pasteur famous. It was named “pasteurization” in his honour, and by about 1900 it had been widely used for processing and bottling cows’ milk. The result was a huge drop in the number of bottle-fed babies dying from infant diarrhea(嬰兒腹瀉)and from that time on it has been a standard treatment for milk and many other food products. This simple process has saved thousands, possibly millions, of lives worldwide.

When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo’s parents set out to prove the doctors wrong.
The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren’t interested in supporting research into such a rare disease.
However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial and error, they finally created a cure from ingredients (調(diào)料) commonly found in the kitchen. The cure, named "Lorenzo’s Oil", saved the boy’s life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it.
Finally, the boy’s father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy.
【小題1】Doctors said that Lorenzo might die within three years because_____ .

Some years ago, writing in my diary used to be a usual activity. I would return from school and spend the expected half hour recording the day’s events, feelings, and impressions in my little blue diary. I did not really need to express my emotions by way of words, but I gained a certain satisfaction from seeing my experiences forever recorded on paper. After all, isn’t accumulating memories a way of preserving the past?
 When I was thirteen years old, I went on a long journey on foot in a great valley, well-equipped with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt proud to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I wandered out of my tent, diary in hand. The sky was clear and lit by the glare of the moon, and the walls of the valley looked threatening behind their screen of shadows. I automatically took out my pen….
At that point, I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley. All I remembered of the previous few days were the dull characterizations I had set down in my diary.
Now, I only write in my diary when I need to write down a special thought or feeling. I still love to record ideas and quotations that strike me in books, or observations that are particularly meaningful. I take pictures, but not very often—only of objects I find really beautiful. I’m no longer blindly satisfied with having something to remember when I grow old. I realize that life will simply pass me by if I stay behind the camera, busy preserving the present so as to live it in the future.
I don’t want to wake up one day and have nothing but a pile of pictures and notes. Maybe I won’t have as many exact representations of people and places; maybe I’ll forget certain facts, but at least the experiences will always remain inside me. I don’t live to make memories—I just live, and the memories form themselves.
【小題1】 Before the age of thirteen, the author regarded keeping a diary as a way of ______.

A.observing her school routineB.expressing her satisfaction
C.impressing her classmatesD.preserving her history
【小題2】What caused a change in the author’s understanding of keeping a diary?
A.A dull night on the journey.
B.The beauty of the great valley.
C.A striking quotation from a book
D.Her concerns for future generations.
【小題3】What does the author put in her diary now?
A.Notes and beautiful pictures.
B.Special thoughts and feelings.
C.Detailed accounts of daily activities.
D.Descriptions of unforgettable events.
【小題4】The author comes to realize that to live a meaningful life is ______.
A.to experience itB.to live the present in the future
C.to make memoriesD.to give accurate representations of it

I was telling my boy Sonny the story of the hare and the tortoise. At the end I said, “ Son, remember: Be slow and steady, and that will win the race. Don’t you think there’s something to learn from the tortoise?”
Sonny opened his eyes wide, “Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”
I was shocked, “But the tortoise didn’t wish that the hare would fall asleep!”
“He must have wished that,” Sonny said, “Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did.”
“He didn’t have such a wish,” I insisted. “He won the race by perseverance, by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he’d never have won the race. That’s for sure.”

Three men were travelling across the desert when their car broke down. There were no other traffics, so their only hope was to walk.
Before they set off, they looked around in the car for useful things to take with them. One of the men took a bottle of whisky. Another took an umbrella. The third unscrewed a door from the car and carried that.
After they had been walking for almost a day, they came across a camel caravan travelling towards them.
“Let’s try to join the caravan,” one of the men said. “It’s going the wrong way but we’ll be safer than if we keep on alone across the desert.”
The other s agreed, so they asked the leader of the caravan for permission to join it.
“You can join the caravan only if you answer three questions,” he said. He pointed to the first man’s bottle. “What is that and why are you carrying it?” he asked.
“It’s a bottle of whisky. I decided to carry it with me so that if I feel miserable and want to give up, I can get drunk, cheer myself up and then keep on walking.”
“Very sensible,” the leader of the caravan said. Then he pointed to the next man and his umbrella.
“It hasn’t rained in the desert for many years,” he said. “Why are you carrying an umbrella?”

It was my first day of high school, and I was late. My next class, Spanish, scared me. I just could not speak that language. As the bell rang, I ran to the classroom.
At the door, a hand reached out and shook mine firmly. I looked up. A man with large glasses smiled. He introduced himself as Profe, which means teacher in Spanish. Right away, his warm smile and welcoming words eased my fears. That year, I enjoyed his classes a great deal because I learned more than just Spanish.
I admit I only speak a little Spanish. But I try to live out the life lessons I learned from Profe. Every day Profe stood outside his classroom before and after class to give his “hand hug”. After school his room was always filled with students and he would talk to and chat with them--even those not in his class. He taught me that every person is worth your time.
One time, I was rejected(排擠)by my friends, Profe told me, “Linda, life gives you ashes. But learning its lessons will turn those ashes to jewels.” Therefore, I learned to look at my troubles differently and not to fear any difficulty.
In my senior year, I became president of one of the school’s clubs, so I was very busy. Many times I didn’t even have time to buy lunch. He served me by giving me his food as well as advice. He lived out what he taught us to do: serve others.
The author William Arther Ward wrote: “The mediocre(平庸的) teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.” Thank you , Profe, for inspiring me.
【小題1】Which of the following is TRUE according to the passage?

A.The writer was on time for his first day of high school.
B.The writer didn’t like Profe’s class.
C.The writer could speak Spanish fluently.
D.The writer learned life truth from Profe’s class.
【小題2】How did Profe treat his class and his students?
A.He was very stict with his students.
B.He only talked with those students in his class.
C.He lived out what he taught in class.
D.He never inspired his students.
【小題3】What can we learn from the passage?
A.The writer benefited a lot from Profe’s class.
B.The writer was good at spanish in the end.
C.Profe treated students differently according to their grades.
D.Profe was not a superior teacher.
