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.

53.         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

54.         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

55         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

56         What is the right order of the steps in the operations?
a. send the cooled 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

Brian Walker chews pens. He bites them so hard that his boss has warned him to stop or buy his own. Kate’s weakness is more acceptable-she is unable to walk past a cake shop without overeating Sophin Cartier finds her cigarette habit a headache, while Alice’s thumb-sucking drives her boy friend crazy. Four people with very different habits, but they all share a common problem anxiety disorder or, in serious cases. Obsessive Compulsive Disorder (OCD).

From nail-biting to too much hand-washing, overeating and internet addiction（上癮）,OCD is widespread in almost every workplace and countless home. “It is a relatively common form of nxiety,”says Dr. Mootee. “The main feature of OCD is the repetition of unwanted obsessive（過(guò)度的） thoughts such as worries that doors are left unlocked , gas or electrical appliances are left on.” In order to fight against the essay checking door locks and gas or electrical appliandces.

 Dr. Mootee says that repetitive washing, particularly of the hands, is the most common type of OCD.  She has treated many patients who wash their hands up to 30 times a day. The technique Mootee uses to treat people with OCD is called cognitive-behavioral therapy（認(rèn)知行為療法）.“It is based on the general idea that people have the ability to change the way they think and behave,”says Mootee.

But when does a habit become a problem? “It’s personal,”says Mootee.“Everyone has something unusual, but if you can’t put up with it, then it’s a problem and you need to do something to change it.”Mootee says many people resist for treatment because they fear they are“crazy”. But as people become more knowledgeable about these problems they will go and get help. The only way to cure is to conquer.

  A. chewing pens           B. hurting himself

71. By saying “The only way to cure is to conquer.” Dr. Mootee suggests that an OCD sufferer   .
