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 back to the monkeys’ brains. When the brain’s temperature was 10℃, 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.
【小题1】.The biggest difficulty in operating on the damaged brain is that ____.

Last week my parents and I took a two-day trip to Emei Mountain in Sichuan.
Like everyone knows, it's famous mountain with all kinds of plants and animals.
The weather was fine. It was about noon we arrived at the foot of the mountain.
The three of them were very excited. As we climbed the mountain, we fed monkeys,
visiting temples and told stories. On the way down I was busy taking pictures since
the scenery was so beautiful. The time passes quickly．Evening came. We spent the
night in a hotel in the top of the mountain. The food was expensive and the service was    
good. I was so tired that I fell asleep at the moment my head touched the pillow．

The first visit to a foreign country that I can remember was when I was about seven years old. We live about 5 miles away from the Canadian border(边界). My family and I went to Parc Safari, Quebec, a wonderful place that has animals and rides. We drove down a nice long road. My sister and I sat in the back of the car, and it was a hatchback(有仓门式后背的汽车) so we opened it up. I remember feeding the animals snacks we had bought for ourselves.
The time we went we were told there would not be monkeys because they had escaped and had not been found. I remember thinking to myself, how cool it would be to see a monkey in our backyard.
Even though the monkeys were not there it was still so much fun. When we reached the area that had camels, giraffes and other animals, I remember one of the camels reached into the car to get our snacks. However, we were a little gross out because the camels seemed to froth(吐白沫) at the mouth and we had camel slobber(口水) all over the car and us.
It was one of the best family vacations that I can remember. It was not too far from home, it was in a different country and it was with my family. I cannot remember if we went on the rides or not but seeing many animals was a great time. Now I am grown up and have a son, and I am planning to go there again. He is 7 years old and I think he is at a great age to enjoy a trip like this. I am sure it has changed a lot over the years but it will still be a great family trip.
【小题1】Where did the author live when he was 7 years old?

When it comes to intelligence, human beings are the top dogs of the animal kingdom. But in recent years, scientists have been documenting surprising intelligence and emotional depth in animals ranging from honeybees to elephants. Here are some amazing examples.
Artistic Monkey Business
Jannet Schmid, director of the Little River Zoo in Norman, Oklahoma, learned a lot about the intelligence of capuchin monkeys. She and her busband adopted a young male, named Bailey. The capuchin particularly liked taking car rides, insisting that he insert the key and ride in the front passenger’s seat.
Now Bailey has become a devoted painter. He uses brushes to create colorful, abstract paintings, and prefers not to be disturbed.
Prairie Dog Sound
Through a variety of birdlike sounds, prairie dogs warn each other of approaching creatures. They demonstrated a surprisingly complex communication system. In his 25 years of study, Slobodchikoff, a professor of biology, has recorded them pronouncing ten nouns including hawk, deer and coyote, a number of adjectives to identify color, size and shape, and even some verbs to indicate speed.
In an ongoing study, Slobodchikoff learns that their brain contains a very extensive vocabulary. He once used his best prairie dog sound to say coyote, and they just looked at him in anger as if he had said a bad word.
Ivy League Parrot
One African grey parrot Alex is said to have the cognitive abilities of a five-year-old child. Alex can identify 50 different objects, seven colors, five shapes, quantities up to six, and the concepts of bigger, smaller, same and different.
Also Alex is considered to make reasoned decisions. During an experiment, researchers gave Alex different-colored blocks in sets of two, three and six. When asked which color group had five blocks, Alex replied, “None.” And he answered the same in repeated tests. Obviously, he interpreted the concept of “none” as an absence of quantity all on his own. That’s a lot like a high school student answering questions on a quiz show.
56.Which of the following is true?
A. Bailey is as clever as a child of five.
B. The prairie dog loves taking car rides.
C. The capuchin monkey is fond of painting.
D. Alex develops a communication system.
57.The underlined word “coyote” in Paragraph 4 refers to ________.
A. a verb                     B. an animal              C. a warning                       D. an adjective
58.The African grey parrot Alex can ________.
A. answer questions on a quiz show
B. understand the figure “7”
C. identify five colors and seven shapes
D. apply the concept of “none” correctly
59.What is the passage mainly about?
A. Animal communication                           B. Animal research
C. Animal intelligence                                  D. Animal information
