Cause and effect is one way to explain things that happen around us. Many things happen because something caused or influenced them to happen. Sometimes it is hard to look at a cause and find out what caused or influenced them to happen. Sometimes it is hard to look at a cause and find out what causes the effect. It may help you to start with the effect and use your reasoning(推理的) skills. Think about all the things you know that could be reasons for the effect you can see.

For example, you may see someone putting on a heavy jacket. This is the effect. To look for a cause, think to yourself, “What would take someone put on a heavy jacket?” Maybe the person is going outside into very cold weather. Maybe the person works in the penguin pen(企鹅圈养地) at Sea World. Maybe the person is going to visit an ice skating rink where the air is kept very cold. All of these things could be a cause for putting on a heavy jacket.

Now, think about a second example. The effect is a boy named Abi has to go to the head teacher’s office. What are the possible causes? Maybe he bullied(欺负) another student. Maybe he is just being picked up early. Maybe he is being given a prize!

Here is another example for you to think about its cause and effect. Cait, 13, was trying to fall asleep when her 8-year-old brother, Doug, came into her room. He looked around a bit, but seemed really out of it. Then Doug went back into the hallway and stood there looking straight up at the hall light for quite a while. Little brothers can be very strange, but this was really much too strange. Cait’s father appeared and explained that Doug was sleepwalking. What’s the cause end effect, could you tell?
