A Trip to the Forest

One day Bob took two of his friends into the mountains. They put up their tents and then rode off to a forest to see how the trees were growing.

In the afternoon when they were about ten kilometres from their camp(营地), it started to snow. More and more snow fell. Soon Bob could hardly see his hands before his face. He could not find the road. Bob knew there were two roads. One road went to the camp, and the other went to his house. But all was white snow. Everything was the same. How could he take his friends back to the camp?

Bob had an idea. The horses! Let the horses take them back! But what would happen if the horses took the road to his house? That would be a trip of thirty-five kilometres in such cold weather!

①Forests help to keep water from running away, so drought does not often happen. The trees in the forests can keep raindrops from hitting the soil directly, and the dead leaves on the ground can also keep the water from running away.②

Chinese people don’t want to see more floods and droughts. We have built the “ Great Green Wall” of trees across the northern part of our country.③ Thanks to the “ Great Green Wall”, we can prevent the wind from blowing the earth away.

We all enjoy the beautiful show of colours as leaves change each autumn. But did you ever wonder how and why this happens?
Leaves are nature’s food factories. Plants take water from the ground through their roots and take carbon dioxide (二氧化碳) from the air. Plants use sunlight to turn water and carbon dioxide into glucose (葡萄糖). Glucose is a kind of sugar, which plants use as food for energy and growing.
The way plants turn water and carbon dioxide into sugar is called photosynthesis that means “ putting together with light”. A chemical called chlorophyll helps photosynthesis. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.
During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories.
As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. Small amounts of these colours have been in the leaves all along. We just can’t see them in the summer, because they are covered up by the green chlorophyll.
The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples (枫树), glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red colour. The brown colour of trees like oaks (橡树) is made from waste left in the leaves.
It is the mixture of all these things that makes the beautiful colours we enjoy during autumn.
【小题1】The word “chlorophyll” in the third paragraph means _______ in Chinese.

A.叶绿素B.氧气C.胡萝卜素D.蛋白质
【小题2】The leaves of the trees in autumn turn yellow because of the short of _____.
A.water and carbon dioxide
B.glucose and energy
C.sunlight and water
D.sunlight and carbon dioxide
【小题3】The way that _______________________ is called Photosynthesis .
A.plants change water and carbon dioxide into sugar
B.plants turn water and carbon dioxide into sugar with the help of sunlight
C.plants use glucose as food for energy and growing
D.chlorophyll is a great help
【小题4】Which of the following is NOT true?
A.When autumn and winter come, the days get shorter and shorter.
B.During winter trees rest and live on the food they store during the summer.
C.During winter small amounts of yellow and orange colours are kept in the leaves all the time.
D.Trees begin to stop making food in summer.
【小题5】This passage tells us __________________.
A.all the plants can grow well with the strong sunlight
B.there are all kinds of plants on the earth
C.all the colours of the leaves aren’t made from chlorophyll
D.maples and oaks have the same reason as other trees for the change of colours
