When it comes to problem solving, many of us have heard of the skills of the crow (乌鸦) in Aesop’s Fables (《伊索寓言》).
In the story, a thirsty crow comes across a bottle of water, but the water level (水平面) is out of its reach. The bird then drops small stones into it until the water level rises enough for the bird to drink.
“Oh, it’s just a fable,” you may think. After all, it’s hard to imagine birds knowing about “problem solving”.
But new research has found that crows’ brains may sometimes be better than those of 6-year-old children.
In a recent experiment, US scientist Corina Logan and her team caught six crows to test them. There were two tubes (试管) of water, one wide and the other narrow (窄的). Each crow was given four stones, enough to help them get the water in the narrow tube, but not the wide one.
Surprisingly, the crows dropped all or most of the stones into the narrower tube and got the food reward! They had found out the cause-and-effect relationship.Using such brains, crows are making their lives easier. For example, some crows in cities have learned to use road traffic for breaking nuts, National Geographic News reported.
But how are their wits (智力) compared to humans’? Logan’s team did another experiment, this time on both crows and children.
Here, the crows and children had to choose between two sets of tubes.
With the red set, when they dropped a stone into a wide tube, the water level raised in a connected narrow tube that contained food.
The blue set of tubes, however, had no connection between them. So dropping a stone in the wide tube did not cause the water level to rise in the narrow tube.
Children aged 7 to 10 were able to learn the rule. Children aged 4 to 6, however, failed.
Five of the six crows failed the test. But Kitty, a 6-month-old crow, passed it. She put all or most of the stones into the red tube.
So, could a bird be more clever than a kindergartner? Don’t be too quick to say no.Why is Aesop’s Fables mentioned in the beginning of the article?
| A．To introduce the idea that crows are smart. |
| B．To show that fables about crows are wrong. |
| C．To explain why crows can solve problems. |
| D．To prove that crows can be better than babies at problem solving. |
What have Logan’s team found out from their recent experiments?
| A．Crows prefer to get their food reward from wider tubes. |
| B．Crows are able to understand or learn cause and effect relationships. |
| C．Crows can easily recognize the tubes with a food reward inside. |
| D．Some crows even make use of road traffic to help them break nuts. |
What can we learn from the experiment on crows and children?
| A．Five of the six crows threw stones into the red tube. |
| B．Children aged 6 did better than children aged 4. |
| C．One crow passed the test while the younger children didn’t. |
| D．Some crows proved to be more clever than children aged 10. |
Who are these people rushing by you in the street? More than 215 million people now call America “home’’, but most of them can trace their families back to other parts of the world. If you look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States, have lost the customs and cultures of their original countries and have become “American’’is really not true. In fact, what exists in America is more often a kind of “side-by-side”, living in which groups of people from other countries often have kept many of their customs and habits. They join the general American society only in certain areas of their lives—such as in schools, business, and sports-but they keep many of their own native customs and manners socially and at home. This living “side-by-side” has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas and dress, food, and social customs in America. Everyone can find some part of his or her familiar world in the United States, in Churches, music, food, national groups, or newspapers.More than 215 million people call America “home” because .

Last Friday, I was coming home late after spending time with friends and thought I’d go down to the $99 cent pizza place. On the way, I saw a man sitting on the stairs alone there. I’d seen him before every day I run late to work, but this time I had no place to rush off to.
There was something about him, a quiet manner, different from many of other homeless people I had seen in New York City. I walked past him, went to the pizza place, and those 10 seconds waiting in line was enough to practice stepping outside of my usual, familiar flow. So with a few slices in hand, I went back to join him. I asked him if he was hungry. He said yes, but not for pizza because it made him uncomfortable. He’d rather have a few bucks for chicken and rice since it was easier on his stomach. It’s funny, in that moment, he became more real to me.
This man I had seen almost every day was someone with specific conditions, needs, and experiences. We exchanged names and ended up talking for a little over an hour that night as Kevin told me stories from his life, how he had done things when “he was younger and didn’t know any better” and how he tried to make amends (补偿) but too much time had passed. He shared his views on the value for young adults to learn the history of other people.
He talked about his one wish being in his 60’s before he leaves this earth, which is to share his story with the teenagers and young adults so they could avoid the mistakes he went through. Throughout the conversation, he eventually got his chicken and rice and gifted me a rose he had been carrying. Shortly afterwards, I made my way home, thinking to myself, “I met an amazing homeless person”.The writer’s purpose in writing the passage is to ____.

It is known to us that computer users are being warned by industry experts to pay attention to secret codes which could be used to record their conversation.
E-mails, screen savers, and electronic greeting cards can carry a secret code which is able to turn on the computer’s microphone, make a recording, and forward it to someone else without the user’s knowledge.
In fact any attachments (附件) sent to a computer, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy (窥探).
Experts say people should always think twice about opening attachments because --- although not common --- bugging (窃听) by computer can and has been done.
Bill Lyons, head of the Internet Security Company Finjan, said, “People in the army have tested this and you can be sure, if people in general are aware of it, then computer hackers (黑客) are aware of it. The frightening thing is that there are tools on the Internet which people, using a simple search method, can find, and which will enable them to attach this dangerous code to simple attachments.”What is the advice given in the passage?
| A．Use secret codes to record other people’s conversation. |
| B．Be careful when opening an attachment. |
| C．Never open any attachments. |
| D．Never use secret codes. |
What worries the experts is that ___ .
| A．nobody seems to believe such things |
| B．nobody knows the danger of the code |
| C．tools can easily be used to tie dangerous codes to e-mails |
| D．effective ways can never be found to deal with the problem. |
Which of the following is TRUE according to the passage?
| A．A moving picture cannot be used to spy. |
| B．Electronic greeting cards cannot carry a secret code. |
| C．A secret code is used to destroy the computer system. |
| D．Any attachments sent to a computer may carry a secret code. |
