Traffic lights are red, yellow and green. They are very important signals (信号). Traffic lights are usually placed at busy street corners to help control traffic Sometimes, they are on streets near schools and shops, too. Most young children are taught what each of the colored lights means, so everybody can stay safe.

The first traffic signals were used for trains. The signals were put alongside railway tracks  ( (轨道). The color red was used to mean "stop" because it warned people of danger. A red light was also the easiest color to see from a distance. Train drivers could see the red "stop" light ahead and had enough time to slow down and stop their trains. A green light was used to mean "take care" and a white light meant "go".

However, there were many dangerous accidents on the train tracks. Some train drivers thought a star shining in the night sky was a white light that meant "go"". So the signals were swapped. The "go" light was changed to green and the "take care" light was changed to white.

During these times, people travelled by train or in carts pulled by horses. Years later, when cars were built, people began to drive them because they could travel much faster than horses. However, the road rules for drivers were not very clear and many people were hurt crossing the roads. Yellow warning signs had to be placed beside the roads to remind drivers to take care and allow people to cross safely.

Today, towns and cities all over the world have traffic lights. Red and green lights match the signals used on the railways. Yellow lights are easy to see, so they are used to warn drivers that they should slow down and prepare to stop.

A lot of animals travel from one place to another. We call this migration.

In Africa, large animals, like elephants and zebras, migrate to find food and water. They usually follow the same ways every year.

A lot of birds migrate to find food and better weather, too. They are usually birds that eat insects. They spend the summer in northern Europe, because there are lots of insects there. In the winter there aren't any insects, so the birds fly south to southern Europe and Africa.

Some insects migrate, too. In North America, millions of monarch butterflies fly south to spend the winter in Mexico, California and Florida, where it's warmer. They travel 50-65 km each day and they travel about 1, 125 km.

Some fish migrate to breed  (繁殖). Salmon (鲑鱼) can swim over 20, 000 km in their life. They are born in rivers in Ireland, Scotland and other places in northern Europe. The young fish swim down the river to the sea and into the Atlantic Ocean. They live in the ocean until they are adults. Then they return to the river where they were born. They lay their eggs in the river and then they usually die. Salmon do this, because their eggs are safer in the river. Other fish can't eat them.

Arctic terns (北极燕鸥) travel the furthest when they migrate. They spend the summer in the Arctic, but when winter comes they fly to the Antarctic, because it's summer there. The next year they fly back to the Arctic again. In one year these small birds travel 36, 000km from one end of the earth to the other and back again. Nobody knows how they do it.

How would you feel if someone decided to take away your park? Well that's what's happening in my community. There's a park that some people want to turn into a golf course  (高尔夫球场). Let me tell you why I think it's a bad idea.

First, a park is meant to be for the whole community. Not everyone likes golf, so not everyone will get to use the park. This isn't fair. A community park should have open spaces for everyone to use.

Second, to make way for the golf course, lots of playground equipment (设施) will have to be moved or knocked down, which is a waste of time and money. It's also a waste of perfectly good equipment. The swings, for example, will probably just end up as litter.

Third, what about giving young people something to do? Not all kids are crazy about golf. At the moment, the park has a skating place and a playground. These attract lots of kids from the community. If you turn the park into a golf course, these kids won't have anywhere to go and they won't have anything to do.

This means that they will stay at home and turn on a video game rather than get some exercise. It also means that they might be out on the street causing trouble. Wouldn't it be better to give them something to do at the park?

Finally, golf is expensive. Building a golf course and maintaining (维护)it costs a lot of money. Who is going to pay to maintain the golf course? What about those people who can't afford to join a golf club? That means that the golf course will only be available to people with lots of money.

Turning our park into a golf course is a bad idea. I suggest we have a community meeting before plans go any further.

27. Some people want to change the park into ______________.

A. a golf club        B. a golf course           C. a park               D. a skating place

28. According to Paragraph 4, having nowhere to go will make some children

A. go to get some exercise                                 B. fall in love with golf

C. play video games at home                             D. go to the street and make friends

29. Which of the following shows the structure of the passage?

 (P=Paragraph)

30. What is the writer's purpose in writing this passage?

A. To help carry out further plans.

B. To make the park more beautiful.

C. To encourage children to go skating.

D. To stop the golf course from being built.

Hopes, ambitions (抱负), dreams. How many of yours will you achieve? When you look back at your life in the future, will you have good memories of all he things that you did? Or will you regret all the things that you didn't do?

Of course, there's no easy road to success, but one thing is certain: success won't come if you don't do anything. So how do you do it? This four-step model will help you to make your dreams come true.

Step 1:    32   

What would you like to do? Write down all your ambitions. They may be very general, such as I would like to be fitter. I want to be famous or It would be nice to have more friends. Or they may be more specific, like I've always wanted to play a musical instrument.

Step 2:    33     

Now you need to do two things:

1. Choose one or two ambitions. If you try to do everything, you won't do anything.

2. Set a time limit (限定). This is very important, because you will have a goal and you will also know when you have reached it.

So, for example, I would like to be fitter. in Step 1 now becomes I will be fit enough to join a half-marathon race by the end of August.

Step 3:    34     

Now that you've made your choice, what are you actually going to do to achieve your goal? So, in our example, I will be fit enough to join a half-marathon race by the end of August. becomes I'm going to join a running club. or I'm going to go jogging three times a week.

Step 4:    35      

This is when you change your intentions (意图) into specific actions. Prepare to do something at a specific time. If you don't do this, your dreams and plans will just stay as dreams and plans. So now I'm going to join a running club. becomes I'm meting the president of the Cheetahs Running Club on Monday evening at 5∶30.

Don't let your ambitions die. Follow this four-step plan and make your dream come true.
