In nature, you may see many insects and animals of different colors. Have you ever wondered why?

Locusts are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops ．When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.

Brown bears, tigers and other animals move quietly through forests. They can't be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark colored and they live under the soil (土壤) in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.

Have you ever noticed some even stranger acts？The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

1.It is not easy for birds to catch locusts because________.

A．locusts are good runners

B．locusts can jump very high

D．locusts can change their color

2.According to the passage, most soil insects________.

4.What is the main ideas of this passage?

How to beat sadness

We all have days when we are down, tired and unhappy. That’s OK. You need days like this, or how would you know you are happy? You’ll enjoy your good days even more when you have a few bad days. Even if sadness is a part of life, let’s try to make it small. Here are a few simple ways to help you feel better when you are feeling sad.

1. Stand up straight and this helps your energy flow (流動(dòng)). When your energy is flowing freely, you can flow too.

2. Smile! It’s easy to do and have good results. This way can not only leave you in a good mood but also bring others a good mood.

3. Listen to music. It can be your favourite music. Some kinds of music work better than others, so try and find out what kind of music works the best for you.

4. Take some “me” time. You can find pleasure in reading a book, watching a sunrise or having a hot bath, or something like that.

5. Exercise. Even something as simple as taking a walk will get your blood flowing. It is a great way to clear your mind of anything that makes you sad.

These ways will cheer you up when you are down, but don’t just use them when you are sad. Try and practice them every day to make them a habit. You will be surprised to learn that these simple ways will keep your sadness away. But if you are in a deep depression (沮喪), go to see a doctor.
