根据短文内容,判断句子正(T)、误(F)。
Most animals are helped by people. They can’t live without us. But sometimes people have made the environment worse. For example, in some parts of the world the forests are being cut down.
The animals in the forests have become fewer and fewer. People hope to grow more food on the land, but the wind blows the earth away. Now forests become smaller and smaller, the soil becomes poorer and poorer. Now there are fewer animals and plants in the world. Insects (昆虫) are usually killed, but some plants need insects. Their seeds (种子) can’t spread without them. Birds eat insects, and without insects many kinds of birds will die.
There are hundreds and hundreds of plants and animals, and each plant is helped by another, so does each animal. If you hurt one, you will hurt another, then another. Scientists know this well. They don’t want people to break their environment.
1.It isn’t good for our environment to cut down forests.
2.Animals in the world are becoming fewer and fewer.
3.Animals and plants helped by each other.
4.After the wind blows, the earth becomes richer and richer.
