It’s difficult for doctors to help a person with a hurt brain. 36 enough blood, the brain can live only three to five minutes. Usually doctors can’t fix the hurt 37 such a short time.
Dr Robert White thinks he knows a 38 of help. He thinks doctors should make the hurt brain 39 to live for 30 minutes without blood. This gives the doctor 40 time to do something for the brain. Dr White experimented his 41 on fifteen monkeys. 42 he taught them to do different jobs. Then he operated on them. He made the monkeys’ blood go 43 a machine. When the brains’ 44 was 10℃, he stopped the blood to the brain. After 30 minutes, he turned the blood back on. He 45 the blood again. After their operations, the monkeys were almost 46 before. They were healthy and busy. Each one could still do the job the doctor 47 them.
Dr White’s idea works well on monkeys. He thinks it will work on 48 . He think it will help with heart problems. A person 49 die when his heart stops; doctors can 50 it again. The problem comes: when the brain is without blood for about 5 minutes, it 51 . If doctors start the heart again after 5 minutes, the person has 52 body but a dead brain. Maybe in the future, doctors will 53 Dr White’s idea. When the person’s heart stops the doctor will 54 cool the brain. They will have 30 minutes to start the heart again. Maybe there will be no 55 the brain.

On August 26, 1999, New York City was struck by a terrible rainstorm. The rain caused the streets to 36 and the subway system almost came to a stop.
Unfortunately, this happened during the morning rush hour. Many people who were going to work were 37 to go home. Some battled to 38 a taxi or to get on a bus. Still others faced the 39 bravely, walking miles to get to work.
I 40 to be one of people on the way to work that morning. I went from subway line to subway line only to find that most 41 had stopped.

So I took the train going in the opposite direction, and then switched back to the downtown train.
Finally, after what seemed like forever, the train 46 my stop. Then I had to walk several blocks in the increasingly heavy rain. When I finally got to my office, I was 47 through, exhausted and 48 .
My co-workers and I spent most of the day drying off. When it was 5:00 pm, I was ready to go home. I was about to turn off my computer 49 I received an email from Garth, my Director:
I would like to thank all of you who made the effort and 50 went to work. It is always reassuring(令人欣慰), at times like these, when employees so clearly show their 51 to their jobs. Thank you.
Garth’s email was short, but I learned more from that 52 message than I ever did from a textbook. The email taught me that a few words of 53 can make a big difference. The rainstorm and the traffic 54 had made me tired and upset. But Garth’s words immediately 55 me and put a smile back on my face.

One cold night，I was growing sick of my life in San Francisco． There I was walking home around one o’clock in the morning after a 26 practice at the theatre． With the opening night only a week away, I was still learning my lines by heart．I was having 27 handling my part-time job at the bank in the daytime and my acting at night at the same time． As I walked I thought seriously about 28 both acting and San Francisco．I had 29 too much of city life．
As 1 walked down the 30 streets under the tall buildings，I felt very small and cold, so I began 31 both to keep warm and to keep away from any possible robbers．Very few people were still out 32 a few homeless people under blankets．
About a block from my 33 , I heard a sound behind me． I 34 quickly, half expecting to see someone with a knife or a gun． The street was empty．All I saw was a shining streetlight． Still，the noise had made me 35 , so I started to run faster． Not until I reached my apartment building and unlocked the door did I 36 what the noise had been．It had been my wallet 37 to the sidewalk．
Suddenly I wasn’t cold or tired any more．I ran out of the door and back to where I'd heard the noise．Although I searched the sidewalk 38 for 15 minutes，my wallet was 39 to be found．
Just as 1 was about to quit the 40 , I heard the garbage truck stop to the sidewalk next to 41 ．When a voice came from the inside, “Alisa Camacho?”I thought I was 42 ．How could this man know my name? The door opened and out jumped a small blonde man with an amused look in his eyes, “Is this 43 you’re looking for?” He asked, holding up something like a wallet．
It was already 3 am． by the time I got into bed． I couldn’t get much sleep，but I had got my wallet back． I also had got back some 44 of city life． I realized the city couldn’t be a bad place 45 people were willing to help each other．
