In Chicago, a computerized system has been developed that controls(管理)traffic on the city’s 235 miles of seven expressways. Now one—a controller—can follow the movement of Chicago’s traffic by looking at a set of lights. The system uses electric sensors(感应器) that are built into each expressway, every half a mile. Several times a second, the computer receives information from each sensor and translates it into green, yellow or red lights on a map in the control room. A green light means traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour, and red means heavy traffic—cars standing still or moving less than thirty miles an hour.

  “See that red light near Austin Avenue?”the controller asked a visitor.“That’s a repair truck fixing the road, and the traffic has to go around it.”At the Roosevelt Road entrance to the expressway, the light kept changing from green to red and back to green again.“A lot of trucks get on the expressway there,”the controller explained.“They can’t speed up as fast as cars.”The sensors show immediately where an accident or a stopped car is blocking the traffic, and a truck is sent by radio to clear the road. The system has lowered the number of accidents by 18 percent. There are now 1.4 deaths on Chicago’s expressway for each one hundred million miles traveled, while in other parts of the county there are 2.6.

  Traffic experts say that the Chicago system is the “coming thing”.Systems like Chicago’s are already in use on some expressways in Los Angeles and Houston.“Chicago has taken the lead,”said New York City’s traffic director and he added,“Chicago’s a good example.”

Like most cultures around the world, the Zulu people of Africa tell stories that have animals as heroes. These stories are meant to entertain, but they are also used to teach important lessons to children. This is one of those stories.
One hot afternoon, Jackal was walking along the rocky road sniffing (嗅) the ground. He was hoping to smell a mouse or a lizard (蜥蜴), or something else that would be good to eat. He was so much lost in sniffing that he wasn’t really paying attention to what was around himself.
Suddenly, Jackal looked up to see his neighbor, Lion, walking straight toward him. He did not have enough time to get away. Jackal had played many tricks (捉弄) on Lion over of something quickly.
“Help! Help!” cried Jackal as he quickly jumped upon a large rock hanging over the road. “The rocks are falling down, and I can’t hold them much longer. We shall both be crushed (压碎) if you do not do your best to hold these rocks back, Lion”
At once, Lion pushed his strong shoulder against the rocks to keep them from moving any further. “I’ll just run over here to get something to stop the rocks,” shouted Jackal as he ran away to safety. Lion stayed leaning against the unmoving rocks for quite a long time before he realized that Jackal had tricked him yet again!
【小题1】Why was Jackal sniffing the ground?

Once there was a huge apple tree. A little boy loved to come and play around it every day. He loved the tree and the tree loved to play with him.
Time went by…the little boy had grown up and he no longer played around the tree every day. One day, the boy came back to the tree and he looked sad. “Come and play with me,” the tree asked the boy. “I’m no longer a kid. I wouldn’t play around the tree any more.” the boy replied. “I want toys. I need money to buy them.” “Sorry, I don’t have money. But you can pick all my apples and sell them. So, you will have money.” The boy picked all the apples on the tree and left happily. The boy never came back after he picked the apples.
One day, the boy returned and the tree was so excited, “Come and play with me,” the tree said. “I don’t have time to play. I have to work for my family. We need a house for shelter. Can you help?” “Sorry, I don’t have a house. But you can cut off my branches to build your house.” So the boy cut all the branches off the tree and left happily. The tree was glad to see him happy but the boy never came back since then. The tree was again lonely and sad.
One hot summer day, the boy returned and the tree was pleased. “Come and play with me!” the tree said. “I am sad and getting old. I want to go sailing to relax myself. Can you give me a boat?” “Use my trunk to build your boat. You can sail far away and be happy.” So the boy cut the tree trunk to make a boat. He went sailing and never showed up for a long time.
Finally, the boy returned after he left for so many years. “Sorry, my boy. But I don’t have anything for you any more. The only thing left is my dying root,” the tree said with tears ①.
“Good! Old tree root is the best place to lean on and rest. Come and sit down with me and rest.” The boy sat down and the tree was glad and smiled with tears ② …
【小题1】----Why did the boy pick all the apples on the tree?
----Because __________.

Once, there was a big apple tree. A little boy loved to climb to the tree top, ate the apples and played around it. With time on, the little boy grew up. He no longer played around it every day. One day, the boy came back, sad. “Come and play with me,” the tree said. “I am no longer a kid.” The boy replied, “ I need money to buy toys.” “I don’t have money..., but you can pick all my apples and sell them.” The boy was so excited. He picked all apples and left happily. The boy never came back after that.

One day, the boy returned. “Come and play with me,” the tree said happily. “I have no time to play. We need a house for my family.” “You can cut off my branches.” So the boy cut all the branches off the tree and left happily. But he never came back since then.

Again, the boy returned and said. “ I want to make a navigation across the sea. Can you give me a boat?” “Use my trunk(主干) to build your boat.” So the boy cut the trunk to make a boat. He went sailing and never showed up for a long time. Finally, the boy returned after he left for so many years. “Sorry, my boy. But I don’t have anything for you anymore. the only thing left is my dying roots.” the tree said with tears.

“I don’t need much now, just a place to rest. I am tired after all these years.” The boy replied.

“Good! Old tree roots is the best place to rest. Come and rest with me.” The boy sat down and the tree was glad and smiled with tears.

You may think that the boy is cold to the tree but that’s how we are treating our parents. The tree is our parents. When we were young, we loved to play with them. When we grow up, we leave them, and only come to them when we need something or when we are in trouble. Whatever we ask for, parents will give everything they have and always be there waiting for us home.
