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, and then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain’s temperature was 10°C, 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.
1. The biggest difficulty in operating on the damaged brain is that _______.
A. the time is too short for doctors
B. the patients are often too nervous
C. the damage is extremely hard to fix
D. the blood-cooling machine might break down
2.The brain operation was made possible mainly by _______.
A. taking the blood out of the brain
B. trying the operation on monkeys first
C. having the blood go through a machine
D. lowering the brain’s temperature
3.With Dr. White’s new idea, the operation on the damaged brain _______.
A. can last as long as 30 minutes
B. can keep the brain’s blood warm
C. can keep the patient’s brain healthy
D. can help monkeys do different jobs
4. What is the right order of the steps in the operation?
a. send the cooled blood back to the brain
b. stop the blood to the brain
c. have the blood cooled down
d. operate on the brain
A. a, b, c, d B. c, a, b, d
C. c, b, d, a D. b, c, d, a

高二英语阅读理解中等难度题查看答案及解析
My father was always a good gardener. One of my earliest memories is standing without shoes in the freshly tilled (翻耕的) soil, my hands blackened from digging in the ground.
As a child, I loved following Dad around in the garden. I remember Dad pushing the tiller (耕作机) ahead in perfectly straight lines. Dad loved growing all sorts of things: yellow and green onions，watermelons almost as big as me, rows of yellow com, and our favorite—red tomatoes.
As I grew into a teenager, I didn’t get so excited about gardening with Dad. Instead of magical land of possibility, it had turned into some kind of prison. As Dad grew older, his love for gardening never disappeared. After all the kids were grown and had started families of their own, Dad turned to gardening like never before. Even when he was diagnosed with cancer, he still took care of his garden.
But then, the cancer, bit by bit, invaded his body. I had to do the things he used to do. What really convinced me that Dad was dying was the state of his garden that year. The rows and rows of multicolored vegetables were gone. Too tired to weed them, he simply let them be.
For the first few years after he died, I couldn’t even bear to look at anyone’s garden without having strong memories pour over me like cold water from a bucket. Three years ago, I decided to plant my own garden and started out with just a few tomatoes. That morning, after breaking up a fair amount of soil, something caught the comer of my eye and I had to smile. It was my eight-year-old son Nathan, happily playing in the freshly tilled soil.
1.Why did the author like the garden when he was a child?
A. He wanted to be a garden-crazy like his father.
B. He loved being in the garden with his father.
C. The garden was full of his favorite food.
D. The garden was just freshly tilled.
2.When all the kids started their own families，the author’s father .
A. stopped his gardening
B. turned to other hobbies
C. devoted more to gardening
D. focused on planting tomatoes
3.What happened to the garden when the author’s father was seriously ill?
A. There was a great harvest.
B. The garden was almost deserted.
C. No plant grew in the garden at all.
D. The author’s son took charge of the garden.
4.Why did the author start his garden with tomatoes?
A. He wanted to honor his father.
B. His son liked the fields of tomatoes.
C. He only knew how to grow tomatoes.
D. He thought tomatoes were easy to manage.
