Scientists in UK have grown a living human "brain". The team at Aston University created tiny bunch of cells which act like a mini nervous system.
They believe it could help find a cure for worse mental conditions like Parkinson’s disease. Professor Michael Coleman is leading the research program. He explained, "We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works. "The experiment involves changing cells from a cancer tumour (腫瘤）and making them behave like brain cells.
Although far from finished, researchers hope the false brain cells will give them a greater understanding of how real brains work. This, in turn, could significantly further research into conditions which affect the brain. Neil Hunt, chief leader of the research group, said, "It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (癡呆)."
The technique could also provide a way to carry on animal test and is being supported by the Humane Research Trust (HRT). The scientists predict that over the next ten years a million people will develop dementia. Professor Coleman believes their findings could change this. He said，"We hope our research will provide scientists with a new and highly relational human experimental model to help them understand the brain better and develop new drugs to control the related disease. However, the biggest challenge at present is that we are greatly short of fund, which will slow our research."

     Einstein's connection with the politics of the nuclear bomb is well known: He signed the letter to President Franklin Roosevelt that persuaded the United States to take the idea seriously, and he engaged in postwar efforts to prevent nuclear war. But these were not just the isolated actions of a scientist dragged into the world of politics. Einstein's life was, in fact, "divided between politics and equations(方程式)."
Sickened by what he saw as the waste of human lives during the First World War, he became involved in antiwar demonstrations. His support of civil disobedience did little to endear him to his colleagues. Then, following the war, he directed his efforts toward reconciliation(調(diào)停) and improving international relations. And soon his politics were making it difficult for him to visit the United States, even to give lectures.
Einstein's second great cause was Zionism(猶太復(fù)國主義). Although he was Jewish, Einstein rejected the idea of God. However, a growing awareness of anti-Semitism(反猶太主義), both before and during the War, led him gradually to identify with the Jewish community, and later to become an outspoken supporter of Zionism.
His theories came under attack. One man was accused of motivating others to murder Einstein and fined a mere six dollars. When a book was published entitled 100 Authors Against Einstein, he retorted, "If I were wrong, then one would have been enough!" When Hitler came to power, Einstein then in America declared he would not return to Germany. While Nazi attacked his house and confiscated his bank account, a Berlin newspaper displayed the headline "Good News from Einstein--He's Not Coming Back."
Fearing that German scientists would build a nuclear bomb, Einstein proposed that the United States should develop its own. But he was publicly warning of the dangers of nuclear war and proposing international control of nuclear weaponry. Throughout his life, Einstein's efforts toward peace probably achieved little and won him few friends. His support of the Zionist cause, however, was recognized in 1952, when he was offered the presidency of Israel. He declined, saying he was too naive in politics. But perhaps his real reason was different:"  Equations are more important to me, because politics is for the present, but an equation is something for eternity."
小題1:The reason why Einstein was against the war was that __
A．he tried to get involved in politics
B．the nuclear bomb could be built by German scientists
C．many people died during the war in vain
D．President Franklin persuaded him to do so
小題2: We can learn from the passage that Einstein __
A．believed in God
B．was proud of being Jewish
C．suggested that nuclear weaponry should be banned
D．made great achievements in peace
小題3: The examples in paragraph 4 are used to prove __
A．many people in support of Zionism hated Einstein
B．the reason why Einstein would not return to Israel
C．Einstein was in danger of being killed
D．Einstein didn't enjoy his popularity in the field Of politics
小題4:What is the structure of the passage?

His family still holds a controlling stake (控股權(quán)) in The New York Times.He was a strong believer in family ownership  of newspapers.He once joked：“My conclusion is  simple.Nepotism works.”

The Brown Bear
My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.
Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!” An agreesive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back---- the sign (跡象) of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.
I held my camera tripod (三腳架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.
Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.
The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break.
Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack----- The first time I felf panic.
Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family reminded clear-headed when panic could have led to a very different outcome.
小題1:The brown bear approached the family in order to _______.
A．catch shore birdsB．start an attack
C．protect the childrenD．set up a barrier for itself
小題2:The bear finally went away after it _______.
A．felt safeB．got injured
C．found some foodD．took away the camera
小題3:The writer and his family survived mainly due to their ______ .
A．prideB．patience
C．calmnessD．cautiousness

The Great Barn Adventure
One morning when I was 11, I explored the town's abandoned round grain barn(谷倉). I found a chained sliding door that was wide enough for me to pass through.
Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (升降機(jī)井) that rose all the way to the top of the barn. On one side was a one­man elevator with a long rope and roller.
I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11­year­old, I decided it would be better to go up than down. So, with shaking hands, I began climbing the wall.
After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and found…absolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher(滅火器)，which I'd always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldn't breathe. I was going to choke to death, and they'd probably never even find my body.
Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky.
I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I'm not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.
小題1:When the author got inside the barn, he ________.
A．noticed a man on the elevator
B．opened the chained sliding door

Mrs. Goff is a math teacher at Lincoln High School. Mrs. Goff and I met my freshman year. Zach Howe and I were on our way to a baseball game when he said he needed to get his stuff from Mrs. Goff’s room. I had no idea who she was then, but he said she was great. Well, he was definitely right.
Last year, I had a college math class that required me to be in the computer lab, which was located directly behind Mrs. Goff’s room. When I struggled in the section, I would go to Mrs. Goff’s and ask for assistance. She told me that I was a little too dependent and not confident enough in my ability.
A little confidence, combined with effort, will do wonders for anyone in anything. If you go into something thinking negative thoughts, negative things will happen. Mrs. Goff taught me that it was OK to make a few mistakes. Mistakes are a part of everyone’s life. She told me that it is how you learn from them that defines your character. A person that learns from his or her mistakes is more likely to be a successful person in life.
This year, I have spent a lot of time with Mrs. Goff. She really helps me instill(逐漸灌輸) confidence in myself and others around me. The encouragement that she has given me made me realize that I can do the same thing for people. Therefore, she has helped my leadership skills and increased my confidence in being outgoing.
Mrs. Goff is a great role model in my life, and I appreciate everything she has done for me. I will never forget the things that she has done for me and the things she has helped me learn and accomplish throughout high school. I hope to be as good a teacher as she and give encouragement that she has for me and all of her students.
