One way that scientists (科学家) learn about man is by studying animals.In this lab, the scientists are studying the relationship between diet and health.

But they are more active.Most of the day, they are running, playing with one another.Also, they are living longer.Mice usually live for two years.Most of the mice in this group are still alive after three years.

阅读表达

If you think you’re too shy and want to be a little bit braver, try the following. You can make it.

Tell people you’re shy.

There’s no need to hide it. When they get to know you are a shy kid, they’ll understand you better. (1) This also helps you feel more at ease in talks.

(2)________________________

When you smile, people think you are friendly and easy to talk to. Remember that other people have such feelings too and most people will stay away from an angry-looking face .

(3)_________________________

If you find it hard to start talks, say something nice about people around you. Think about how great you feel when someone says something nice to you. Doesn’t it make you want to keep talking to that person?

Get your attention elsewhere.

Think about more ways to enjoy the party or the game. Don’t waste time worrying about your looks or whether people like you or not.

Take one small step at a time .Each time after you say “Hi” or smile at someone for the first time, say to yourself “You did it!” Or it could be something bigger, like buying yourself an ice cream.

Keep trying and you’ll never be shy when you talk to others one day.
