Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there are pains all over your body. You don’t want to work, you stay in bed, feeling very sad.
What makes us ill? It is germs (細菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a microscope. They are very very  small and there could be hundreds of them on a very small thing.

In America, when people say ‘man’s best friend’, they don’t mean another person. Instead, they are talking about a lovely animal—a dog! These words show the friendship between people and animals. Dogs and other pets can give joy to people’s lives. Some people even leave all their money to their pets when they die!

Do you ever feel a stomachache during a test? Are you ever so worried about something that you even have a headache or can’t sleep at night? If so, then you know what stress is. Stress is what you feel when you are worried about something. You may feel angry, sad, scared, or afraid —all this can give you a stomachache or a headache.
There are different kinds of stress. Some kinds of stress are good and others are bad. Good stress may happen when someone asks you to answer questions in class or when you have to give a report. This kind of stress can help you to finish things better.
