When you are in England, you must (必须) be very careful (当心) in the streets because the traffic goes on the left. Before you cross the street, you must look to the right first and then the left.

If the traffic lights are red, the traffic must stop(停止). Then the people on foot can cross the road. If the lights are green, the traffic can go and people on foot mustn’t (禁止) cross.

In the morning and in the evening, when people go to or come back from work, the streets are very busy. The traffic is the most dangerous then.

When you go by bus in England, you have to be careful, too. You must always remember the cars drive on the left.

In many English cities, there are big buses with two floors. You can sit on the second floor. From there, you can see the city very well. That’ll be very interesting.

There is not enough oil in the world now. As time goes by ,it becomes less and less ,so what are we going to do when it runs out? Perhaps we will go back to use horses ,carriages and bicycles .
In the Second World War ,some people didn＇t use gas made from petroleum （石油）in their cars .They made gas from wood and plants instead . The cars didn＇t go fast ,but they ran ,so this was better than nothing. However, in the future, we can＇t cut down all our trees to make gas; we need our trees for other things, too.
Besides different types of gas, we can also use electricity(电)to run our cars but first we must make the electricity ！Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big ,strong rivers and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.
We are also able to get power from the ocean tides. We put turbines into the mouth of the river .Then the tide comes in ,the water turns the turbines and then it goes out ,it turns them again.
Which of these ways will be used to run our cars in the future?
【小题1】When might people have to go back to using horses and carriages?

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.”
