【推荐1】The natural world is colorful with humans, plants and animals showing different colors.

Human skin can be many different colors and it changes with the sun, our feelings or our health for example. This is because of pigments(色素), which reflect light and make what the eye sees as colors. So, when we feel excited or angry, our heart can send more blood to the face and the pigments in the skin become red.

Plants also have pigments. Colors are important for them to live on. The bright colors of flowers catch the attention of insects, which then carry their pollen(花粉) from one flower to another. Bees can see colors we cannot, and they follow these to the inside of the flower. Without bees visiting flowers in this way, many plants would die out.

Animals also use colors for their own need. They protect themselves with different colors in order not to be seen by predators. The snowshoe hare, for example, a type of wild rabbit, changes colors with seasons for this reason. During summer it is a brown color, and in winter it is white so that it can hide in the snow. However, some animals use the color as a warning to make predators stay away. Bright colors such as yellow and red are often used in this way.

So, we can see that there may be many different reasons and uses for colors in the natural world. Some uses of colors in nature remain unknown, but one thing is for sure, colors not only make our planet beautiful but they are also necessary for our planet to live on.

【推荐2】In nature, youmay see many insects (昆虫) and animals of different colors. Do you know why?

Locusts (蝗虫) are very delicious food for birds, but itis not always easy for birds to catch them. That is not because locusts are good jumpers or runners. Is that because they are smarter than their enemies (敌人)? The answer is “no”. The reason is that the colors of locusts change with the colors of crops (庄稼). 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 the colors like the trees. For the same reason, polar bears are white like the color of snow. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the dark and wet soil. However, insects with colors different from plants can easily be found and eaten by others. In order tosurvive,they have to hide themselves in the daytime and come out only at night for their safety.

The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over (喷洒), itsenemies will find themselves suddenly in a dark world. At the same time the ink fish swims away at once. That is how it keeps itself safe though it is not strong at all.

【推荐2】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。

Have you told a lie?     1     However, scientists have found that lying can make it difficult for your brain(大脑) to finish more important things.

Lying takes much more hard work for your brain to do than telling the truth.     2     Also, when asked more questions about their story, they must give an answer at once. Here’s an example.

Imagine you’re late for class and the teacher asks why and you decide to lie. So you say, “I had to stop by the library and pick up a book.” Your teacher asks, “The book I asked to read last week?” If you say yes, the teacher might ask to see the book. So you might say, “No. It was a different book.” You’re only two sentences into the lies, but you just give your brain a lot of extra(额外的) work.     3    

The prefrontal cortex(前额皮质)is the part of the brain people use when they are lying.     4     Using too much brainpower(脑力) to lie means there’s less available for other things.

Lying is even harder for young people.     5     So, when young people are getting used to lying, they’ll have a harder time doing other things, like making study plans or following a healthy diet(饮食). So think twice before lying next time.

A．Or she might expect you to read from it in class.

B．Most of us have told a lie at one time or another.

C．It would have been far easier just to have told the truth, “I got up late.”

D．When lying, people have to make sure their story sounds real.

E．That’s because the prefrontal cortex is not fully developed until age 25.

F．That area takes care of short memory, planning, problem-solving and self-control.
