What do you think is the most common illness? Do you get ill sometimes? We are lucky to live now because there are lots of medicines to make people better．

     The most common illness in the world is the cold．It often begins with a sore throat．Then you sneeze and your nose runs．You usually have a headache，too．Often you cough later．It's not a very bad illness but you can feel quite ill．   

     There isn't a cure(治愈)for a cold but you can take medicines to make you feel better．For instance aspirin(阿司匹林)can stop your headache．It is good to rest and to drink a lot of water，too．A doctor once said to me，“With the proper medicine a cold will last for seven，days．With no medicine it will go on for a whole week!”

     Where does our medicine come from? A long time ago people knew that some plants made them feel better．They ate the leaves，the roots，the I fruit or the seeds of those plants．For instance the juice of lemons makes a sore throat feel better．

     In modern times scientists have looked at these plants and found out which chemicals(化学物质)are in them．Many of our medicines today are made from those chemicals．   

     There are some illnesses which we can't cure yet．And nobody has found a cure for old age．But because of modern medicines most people now live longer than their grandparents．   

    Are your parents often angry with you? Or you always disagree with your parents. Maybe the relationships between you and your parents are terrible. It's difficult to make your home a happy and healthy place. In fact, you can change the situations by the following keys.

    Respect（尊重）   It's important to show your respect and care about your parents feelings. Though you have disagreements（分歧）, at least try to understand whatever they are trying to tell you. You shouldn't keep your own thoughts only.

    Communication   You can communicate with your parents in a polite way. You may not get what you want, but explaining your thoughts calmly and rationally（理性的）may show your parents that you are no longer a kid.

    Trust   How can your parents build trust in you? It depends on what you do. For example, if you get home late without calling first, next time your parents may not believe you. To earn（赢得）their trust, you must pay attention to the ways you do things instead of fighting with them. It will make your life much easier.

    Taking time together   Some teens find that sharing time together can build trust and communication. Your parents may be interested in going shopping, hanging out and playing cards with you. Spending time together will drive away the“black cloud”hanging over your home.

    Your parents give all their love to you. Why not these ways actively to own a happy family as you want?

    May: I'm 35. I like shopping, but shopping with young children is not an easy thing. I have to look after them while I'm shopping. Shopping with my husband is not fun, either. I only go shopping with my husband when I need to buy something for him. If I look at dress for myself, he always says something like "the queue is too long" or "you don't need to buy that right now". I often go shopping with my friends. It's fun. I like shopping alone, too.

    Lisa: I'm 26. I like shopping very much, but I never go shopping at weekends. There are too many people in the shops. I don't like shopping with other people. It usually takes me a lot of time to choose things because I never buy the first things I see. I always look around other shops to find the clothes with the best price. I'm good at finding the best deals. I don't like buying food in small shops and street markets. I think food in the supermarket is fresher and cheaper. So I usually shop there.

Information Card

    Emperor penguins are the largest penguins on Earth. Each adult is over a metre tall, and can weigh up to 40 kilograms.

    For many months each year, emperors live near the sea in large groups called colonies. However, in May, the weather gets colder and ice covers large areas of ocean. Each colony moves many kilometres from the water.

    Sharing the work

    There, each mother penguin lays just one egg. Then all the hungry mothers must walk back to the ocean to find food. The father penguins put their eggs on top of the feet, under a special piece of skin called the brood pouch. For two months, the father penguins keep the eggs safe and warm. Antarctica. Most animals leave for warmer places, but the father penguins stay. In this time, without food, a father penguin can lose almost half of his weight.

    New life

    Then the babies begin to hatch! The mother penguin returns just in time to see her baby come out of its egg. The chick is then moved to her bored pouch. This can be difficult. If the chick falls, it can freeze quickly, so the penguin parents must be very careful! Once this is done, the father penguin can go back to the ocean to find food.

    Growing up

    Over the next few months, penguin parents take turns to go to the ocean for food. They each make the trip several times, bringing back food for the chick. The chick grows quickly and is always hungry.

    Into the water

    By December, winter is ending. The chick is five months old and can live on its own. Soon it enters the water for the first time. It will swim and eat until next April, and then return here. After a few more years, it, too, will start its own family.
