As you dash outdoors in the middle of winter, you might make it halfway down the block before realizing that your ears are freezing because you forgot your hat.
Now, scientists have shown that even though you’ve had an apparent memory lapse(丧失), your brain never forgot what you should have done.
Memory works mainly by association. For example, as you try to remember where you left your keys, you might recall you last had them in the living room, which reminds you that there was an ad for soap on television, which reminds you that you need soap, and so on. And then, as you’re heading out of the door to buy soap, you remember that your keys are on the kitchen counter. Your brain knew where the keys were all along. It just took a round-about way to get there.
Now, scientists at the Salk Institute for Biological Studies are studying associative memory in monkeys to figure out just how this complicated process works.
First, the researchers trained a group of monkeys to remember arbitrary(任意的) pairs of symbols. The researchers showed the monkeys one symbol(cold weather) and then gave them the choice of two other symbols, one of which (a hat) would be associated with the first. A correct choice would earn them a sip of their favorite juice.
Most of the monkeys performed the test perfectly, but one kept making mistakes.
“We wondered what happened in the brain when the monkey made the wrong choice, although it apparently learned the right pairing of symbols,” said study leader Thomas Albright.
Albright and his team observed signals from the nerve cells in the monkey’s inferior temporal cortex (ITC), an area of its brain used for visual pattern recognition and for storing this type of memory.
As the monkey was deciding which symbol to choose, about a quarter of the activity in the ITC was due to the choice behavior.
Meanwhile, more than half the activity was in a different group of nerve cells, which scientists believe represent the monkey’s memory of the correct symbol pairing, and surprisingly, these cells continued to work well even when the monkey chose the wrong symbol.
“In this sense, the cells ‘knew’ more than the monkeys let on in their behavior,” Albright said. “Thus, behavior may vary, but knowledge endures.”

On March 23, 2010, Google Inc took a major step in withdrawing(收回) its search-engine services from Beijing to Hong Kong. Google acknowledged that it failed to make progress in talks with the Chinese government for permission to let Google stop censoring(审查) its search results.
Since posting the announcement on its website, Google’s stock(股票) price has fallen from $595 to about $567, while Baidu, the leading search engine in China, has seen its stock price rise by 50%. A potential foreign beneficiary(受益者) is Bing, Microsoft’s new search engine. And while Bing may not exactly have got the keys to a very rich kingdom, its managing group understand their good fortune and have not been shy about sticking the knife into Google. Craig Mundie, a chief officer of Bing, told China Daily that “we feel good enough now,” adding, “but it’s a 20-year journey, and not just three years. And Microsoft is here to stay.”
Several other Chinese Internet companies are no doubt moving swiftly to take advantage of this situation. Both Sohu. com—a Yahoo-like website in China— and a hugely successful instant-messaging company called Tencent(腾讯) are already trying to hire Google China staff. Analysts believe that of the two, Tencent is in the better position. Nearly 70% of China’s 400 million Internet users use instant-messaging, and of those, 80% use Tencent’s system, known as QQ. That’s the major reason why Tencent’s potential market is bigger than Baidu’s, and an insider at the company acknowledges that the search business is full of opportunities.
All the competitors of Google do what the Chinese government requires: censor their search results. If Microsoft and the others intend to be in China “to stay,” as Craig Mundie put it, there is no chance that the censoring principle will change for them.
As to the Google’s exit, one of its investors made the comment recently, “There’re still a lot of us who believe that they’ve made the wise choice. But Google is apparently out and I guess we just get to accept.” However, some Chinese netizens regretted the loss of its professional services on google. cn, such as maps, videos, music and translations.
73.Google.cn stops its business in China because _____.
A. too many companies enter the market         B. its stock price has fallen sharply
C. Chinese companies hire its workers           D. it refuses to censor the search results
74.How many Chinese beneficiaries are mentioned in the passage?
A. Two.               B. Three             C. Four.               D. Five.
75.When Google withdraws, _______.
A. Chinese netizens won’t have any professional service
B. only Chinese companies will provide search service
C. China’s attitude towards censoring won’t be changed
D. the Google managing group will regret its decision
76.A suggested title for this news would be ______.
A. When Google Withdraws From China        B. Who Wins in China’s Search Business
C. Who Will Profit When Google Exits         D. Why Google Loses to Other Competitors

I started winning competitions. We still had very little money -- my father had to borrow $5,000 to pay for a trip to the International Young Pianists Competition in Ettlingen, Germany, in 1994, when I was 12. I realized later how much pressure he was under. Tears streamed down his face when it was announced that I'd won -- earning enough money to pay back our loan.

It was soon clear I couldn't stay in China forever. To become a world-class musician, I had to play on the world's big stages. So in 1997, my father and I moved again, this time to Philadelphia, so I could attend The Curtis Institute of Music. Finally our money worries were easing. The school paid for an apartment and even lent me a Steinway(斯坦威钢琴).At night, I would sneak into the living room just to touch the keys.

Now that I was in America, I spent two years practicing, and by 1999 I had worked hard enough for fortune to take over. The Chicago Symphony orchestra heard me play and liked me, but orchestra schedules were set far in advance. I thought I might join them in a few years.

The next morning, I got a call. The great pianist Andre Watts, who was to play the "Gala Benefit Evening" at Chicago's Ravinia Festival, had become ill. I was asked to replace him. That performance was, for me, the moment. After violinist Isaac Stern introduced me, I played Tchaikovsky's Piano Concerto No. 1. My father's mouth hung open throughout the entire song.

I played until 3:30 a.m. I felt something happening. Sure enough, it was a great success. Still, my father kept telling me, "You'd better practice!" But living in America with me was beginning to relax him. In Beijing I'd been fat -- he made sure I ate -- and he'd been skinny. Now I was getting thin. He wasn't.

My father and I had often practiced a piece called "Horses," a fun version for piano and erhu. One night in Carnegie Hall, after I played Chopin and Liszt, I brought Dad out on the stage, and we played our duet(二重奏). People went crazy -- they loved it. My father couldn't sleep for days. He was too happy to sleep.

There have been lots of concerts in Carnegie Hall, but for me playing there was especially sweet when I remember the cold days in Beijing. Together, my father and I worked to reach the lucky place where fortune spots you, and lets you shine.

In the first paragraph his father cried when it was announced that he'd won mainly because__________.

A.his father was excited that his son succeeded at last.

B.his father was under too much pressure.

C.they could pay back the loan with the prize.

D.his father was proud of him.

A. a, e, c, b, d       B. b, e, a, d, c       C. d, a, e, b, c       D. a, e, d, b, c

Which of the following statements agrees with the author?

A. The writer’s father had been very fat before they went to America.

B. The writer thought he would be one of them soon when he knew the Chicago Symphony orchestra heard him play and liked him.

C. The Curtis Institute of Music finally eased their money worries.

D. One can achieve his dream if he is lucky enough.

The underlined word there in the last paragraph refers to_________.

A. America     B. Beijing.   C. Carnegie Hall  D. All the places he went to. 

What is the best title of the passage?

A. I Took Off!                          B. When Fortune Spots Me.

As a substitute teacher, my daily routine involves driving to a new school almost every day so I’m usually unable to anticipate the day’s events, good or bad!
On one particular day, I was teaching in a very difficult classroom. I was managing behavior all morning and by lunch time, I knew I needed coffee to even consider surviving the afternoon. So on my lunch break, I drove to a nearby plaza(购物中心)to get a cup of coffee. Upon returning to the car I realized I had locked my keys and my phone inside! I had about 15 minutes to get back to the school which was a good 4 or 5-minute drive away. I contemplated  (思考)sprinting(冲刺)back, but it being winter, I thought a nasty fall on ice would only make the situation much worse.
So I ran into a McDonald’s which was in the same plaza and asked the man at the counter who happened to be the manager to please call me a cab. I briefly explained my situation to him, and I could tell by the look in his eyes, that he empathized. He hurried to the back to use the phone while I paced in the restaurant. I had less than 10 minutes to get back to my school at this point.
The manager returned only to tell me that the cab company had put him on hold and then the line got disconnected, and that he was now on hold again, but had not yet been able to request the cab yet. My expression, I assume, began to resemble some combination of hopelessness and fear.
Without a thought, he grabbed his coat and offered to drive me to the school. Without hesitation, I followed him into his car and made it back into my classroom with 2 minutes to spare before the bell!
Upon arriving at the school, I thanked this man endlessly. His calm demeanor(举止)and kind nature made me think he was probably a wonderful manager to work for, and also a wonderful human being to have on this earth. This experience makes me realize that out of every seemingly hopeless situation, there is the opportunity for acts of kindness to transpire(发生), which can have an unimaginable impact on those who receive them.
