Number　 sense is not the ability to count. It is the ability to recognize a 　 1　 in number. Human beings are born with this ability. 2 ，experiments show that many animals are, too. For example, many birds have good number sense. If a nest has four eggs and you remove one, the bird will not　 3 . However, if you remove two, the bird 4 leaves. This means that the bird knows the 　5　 between two and three.

Another interesting experiment showed a bird's 6 number sense. A man was trying to take a photo of a crow(乌鸦)that had a nest in a tower, but the crow always left when she saw him coming. The bird did not 7 until the man left the tower. The man had an 8 .He took another man with him to the tower. One man left and the other stayed, but they did not 9 the bird. The crow stayed away until the second man left, too. The experiment was　 10 with three men and then with four men. But the crow did not return to the nest until all the men were 11 .It was not until five men went into the tower and only four left that they were 12 able to fool the crow.

How good is a human's number sense? It's not very good. For example, babies about fourteen months old almost always notice if something is taken away from a 　13 group. But when the number goes beyond three or four, the children are 14　 fooled.

It seems that number sense is something we have in common with many animals in this world, and that our human 15 is not much better than a crow's.

By the third year of teaching I’d begun to expect Christmas break more for the school holiday and less for the excitement of the children. I was teaching fourth grade and my students had made me   16  . I just had to get through one of the hardest days of the school year.
　　The morning bell rang. I walked   17  through the cold into the overly heated school building. Twenty-two smiling faces  18  me at the school bus stop. I forced myself to   19  their smiles. Back into the classroom, they   20 , comparing plans for the   21  . I had to remove one student from each arm   22  I could take a seat at my desk for my morning duties. Before I could find my roll book（点名册） my desk was covered with   23  and gifts followed by a   24  of “Merry Christmas” wishes.
　“Oh, thank you,” I must have  25  a million times. Each gift was truly special to me, except my   26  mood. It was kind of them to  27  me. After a while, I heard a small nervous   28  say my name. I looked up to see Brandon standing   29  by my desk, holding a small, round gift. “This is for you.”
　 “Thank you, Sweetheart.” I laid it on my desk with the others.
　“Um, could you   30  it now?”
　I gently tore at the paper and tape. “  31  ,” he said, “it’s breakable.” Slowly I opened a small, green Christmas tree ornament（装饰物）, complete with a hook already 32 . It dawned on me what he had done. Then a nearby student said that he just pulled that off his own tree. I tried to keep my   33  back.
　Later that day, I sat   34  the ornament in my hands. Was I really so important to this child that he had searched for something to give me? Now every year as I   35  pull a green Christmas ball from my ornament box, I remember the deep influence my students have on me.

       Be Brave With New Things

   The old advertising slogan, “so simple a child can do it ,” has taken on new meaning to me. A few weeks ago I got a computer, but I an mechanically illiterate. I knew that children had no fear of the future, so that seemed a good place to seek help. I asked my nephew, twelve years old, at an elementary school, to help me.

   My nephew took the machine for granted and has simply accepted the fact that computers are now a way of life. He plays with them and does his homework on them and even creates programs for them. I , on the other hand, are terrified by what this equipment can do. It can interchange paragraphs, switch words around and even correct my spelling. It informs me of Its limitations, takes commands and asks questions. It even seems to have a sense of communication. Rather than accusing me of making an error, it prints “One of us has made a mistake!” It never gets tired and is always patient and ready to go when I am.

   I think it was somewhat normal for me to be suspicious of computers. They represent a break with some very familiar habits and traditions. It is only human to instinctively avoid anything that shifts thoroughly from the acceptable, comfortable past. But the world is governed by ceaseless change and we must therefore establish links with the present and future as well as the past. Computer technology is an excellent case in point, as the newest systems grow out of date in only a few years, or even months.

   This ability to see, experience and accept the new is one of our saving characteristics. To be fearful of tomorrow, to close ourselves to possibilities, to resist the inevitable, to advocate standing still when all else is moving forward, is to lose touch. If we accept the new with joy and wonder, we can move gracefully into each tomorrow. More often than not, the children shall lead us.

6．What is the new meaning of  “So simple a child can do it” for the author?

A．computers are so easy to operate that even a child can play them well

B．A child can always do more complex things than an adult.

C．It is easier for a child to accept new things than for an adult.

D．A child has greater ability than an adult in operating computers.

7．According to the second paragraph, which of the following statements is true?

A．The nephew thought it is natural to accept the fact that computers are now a way of life.

B．The nephew believed that machines were made for people to do whatever they wanted.

C．computers are not only used to communicate, but also to remove their limitations.

D．It is a fact that both adults and children have accepted computers as a way of life.

8．Which of the following doesn’t the author’s computer do ?

A．It asks the author if she has made a mistake.

B．It accuses the author of making mistakes.

C．It corrects the author’s spelling mistakes.

D．It informs the author of her mistakes.

9．According to the third paragraph, it is human nature that we resist those things which   

A．only represent the comfortable and acceptable past

B．change thoroughly into the comfortable and acceptable past

C．make people stand still when all else is moving forward

D．change completely from the acceptable and comfortable past

10．How do you understand the underlined sentence in the  text?

　　A. It is always ready to inform me when I am ready to go.

　　B. It is always ready to start working when I am ready for work.

　　C. When I am ready to go, it is patient to wait.

　　D. When I am ready to go, it has already gone.

Directions: Read the following passage. Fill in the numbered the blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.
The World Bank, the United Nations and the London School Of Hygiene and Tropica1 Medicine did a study to urge hand-washing around the world. They found that one million lives could be saved each year if people washed their hands with soap often. They said that programs to increase hand-washing with soap could be among the most effective ways to reduce infectious disease.
Doctors say, many diseases can be prevented from spreading by hand-washing. These include pinworms (寄生虫), influenza (流行性感冒), the common cold, hepatitis (肝炎) A, meningitis (脑膜炎) and infectious diarrhea (腹泻).
Hand-washing destroys germs from other people, animals or objects a person has touched. When people get bacteria on their hands, they can infect themselves by touching their eyes, nose or mouth. Then these people can infect other people.  
The experts say the easiest way to catch a cold is to touch your nose or eyes after someone nearby has sneezed or coughed. Another way to become sick is to eat food prepared by someone whose hands were not clean.
The experts say that hand-washing is especially important before and after preparing food, before eating and after using the toilet. People should wash their hands after handling animals or animal waste, and after cleaning a baby. The experts say it is also a good idea to wash your hands after handling money and after sneezing or coughing. And it is important to wash your hands often when someone in your home is sick. The experts say the most effective way to wash your hands is to rub them together while using soap and warm water．They say you do not have to use special antibacterial soap. Be sure to rub all areas of the hands for about ten to fifteen seconds. The rubbing action helps remove germs. Then rinse (冲洗) the hands with water and dry them.
