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.
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

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

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

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

Which of the following is not true?

A.If there isn’t enough blood, the brain can live for only three to five minutes.
B.If the brain is very cold, it can live without blood for half an hour.
C.Dr. White tried his idea for thirteen times.

There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives. So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn .
Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!
If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet. If someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.
Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction say this is talking about the birds and bees.
Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still.

The problem is that Jean’s family are so busy that they can hardly find time to be with her. In fact, Jean is quite lonely. So Jean spends a lot of time on her QQ. She likes being anonymous, talking to people who do not know about her famous family and her rich life. She uses the name Linda on QQ and has made a lot of friends who she keeps in touch with quite often.
Last year Jean made a very special friend on QQ. His name was David and lived in San Francisco. David was full of stories and jokes. He and Jean had a common interest in rock music and modern dance. So it always took them hours to talk happily on QQ and sometimes they even forgot their time. Of course, they wanted to know more about each other. David sent a picture of himself: He was a tall , good looking young man with big , happy smile. As time went by, they became good friends and often sent cards and small things to each other.
When Jean’s father told her that he was going on a business trip to San Francisco, she asked him to let her go with him so that she could give David a surprise for his birthday.

You might say that Barack Obama was elected President of the US because he knows how to give a good speech. In 2004, the little-known Obama gave a speech at the Democratic national Convention(民主党全国会议). It was a great speech---poetic, and inspiring. The people who heard it would remember it for a long time.
Since 2004, Obama has written and delivered thousands of speeches. These are usually praised for two reasons: he treats the audiences like intelligent adults, and he is able to express difficult ideas in a straightforward, natural way.
Before becoming President, Obama was a lawyer, a college professor, and a successful writer---his two memoirs have become best-sellers. The skills he needed to succeed in his previous jobs have also contributed to his success as a speechmaker.
As a lawyer, Obama learned how to make strong, convincing arguments. As a professor, he learned how to explain complex subjects in ways that helped students understand without boring them. As a writer, he learned how to use language to have a powerful influence on his audience.
Secret weapons of Obama
Writing team: Obama has a team of people who write his speeches. The writers chat with Obama for hours about what he wants to say. They listen to recordings of past presidential addresses and seek advice from advisers. Obama usually edits and rewrites the drafts several times.
Make fun of the guests: Obama starts his speech by gently making fun of his guests. His opening lines attract the audiences’ attention while giving them an opportunity to relax and laugh at themselves and each other.
Making fun of himself: Obama laughs at his past mistakes and is never afraid of showing them to the public.
Obama delivers speeches to audiences large and small. He can make his audiences laugh or cry. His speeches are always thoughtful, well written, and just right for each occasion.

A group of students in Japan have created a realistic robot baby to motivate young people to start planning a family so as to increase the country’s birth rate. The automated (自动化的)doll developed at the University of Tsukuba, called Yotara, laughs and “wakes up” when a rattle is shaken.
He can become angry and sleep like a real baby and he smiles when his stomach is pressed. The robot can also sneeze and have a runny nose, thanks to a heated water pump system. The students of the Graduate school of Comprehensive Human Science at the university created the robot last year with touch sensors. A projector sends the facial features onto a warm silicon balloon which makes up Yotara’s face. The robot’s facial expression and body movements change according to pressure applied to different parts of its body.
The information collected through touch sensors(传感器)under the silicon skin is processed by a special programme. It then changes the baby’s expression projected onto the balloon-face from behind. There is a hat on the robot’s head and a colorful blanket covering the robot’s limbs which simulate wiggling(摆动) with the help of a geared motor. “We wanted to create a new type of robot that is soft, cuddly and cute,” said project leader Hiroki Kunimura.
“We’d like people to experience the innocent, joyful expressions typical of small babies. Through this experience, it would be great if some people started feeling that they wanted to have their own baby, if they started feeling that work is not everything.”
Japan’s birth rate is among the lowest in the developed world at 1.37%, compared to 2.12% in the United States and l.84%in Britain. Japan is facing serious economic consequences with over a quarter of its citizens expected to be aged over 65 by 20l5.The population is expected to reduce by a third within 50 years if the birth rate does not increase.
. What is the students’ purpose of creating such a baby?

A.To help old people who live alone. B.To give small children some pleasure
C.To comfort lonely young people. D.To increase the population of Japan.

What’s the new type of robot like in Hiroki Kunimura’s mind?

A.It can do everything for humans. B.It is clever, humorous and loyal.
C.It is gentle, lovely and smart. D.It makes humans unhappy.

. What can we learn from the passage?

A.Many young people in Japan don’t want to get married.
B.There may be a lack of workers in Japan in the future.
C.The lifespan(寿命)of Japanese people will decrease in the future.
D.The birth rate in Japan will start to increase slowly soon.
