题目内容
【题目】—Can you come to my birthday party tomorrow evening, Linda?
—If my homework _________,I will go to your party.
A.finishesB.is finishedC.will finishD.will be finished
【答案】B
【解析】
句意：——Linda，你明天晚上能来我的生日聚会吗？——如果我的作业完成了，我就去你的聚会。
考查if引导的条件状语从句和一般现在时的被动语态。finishes完成，一般现在时；is finished被完成，一般现在时的被动语态；will finish将完成，一般将来时；will be finished将被完成，根据主语my homework发不出谓语动词finish这个动作可知，应该用被动语态，排除A和C，由if引导的条件状语从句，遵循“主将从现”原则，由所给空在从句中，可知，应该用的是一般现在时的被动语态，排除D，故选B。

A rain forest gets huge amounts of rain. That’s why it’s called a rain forest! More than 100 inches of rain fall there each year. In contrast, Los Angeles, California, gets only about 15 inches of rain per year.
Rain Forest Plants and Animals
A rain forest has hundreds of kinds of trees and flowers. Under your feet is a carpet of leaves.Moisture (水气) is dripping everywhere. Hardly any light reaches the ground because tall trees form a canopy (树冠), or upper layer, high above. It hides the sky and provides shade.
A rain forest is noisy! Bird squawk. Thousands of insects buzz and hum. Monkeys chatter in the trees. Beetles grow as big as your hand. Some frogs grow as big as a milk carton!
Why Are Rain Forest in Trouble?
Rain forests are very important to life on Earth. They recycle. Tree roots use dead plants as food. Rain turns into clouds that make more rain. Trees take in carbon dioxide (二氧化碳) and gives off the air we breathe.
Yet rain forests are in trouble. People cut down trees to get wood and land to farm. Most trees are not replaced. Many scientists think this may be a cause of global warming. Loggers also may leave rubbish behind. This is a kind of pollution.
The balance of life in a rain forest is complicated (复杂的). Plants and animals depend on one another. If one dies out, others do, too.
The Children’s Rain Forest
Children in a Swedish school were studying rain forests. They learned that rain forests were in trouble. The class stated a project to save a rain forest in Costa Rica. The class bought about 15 acres of land. They paid 525 per acre. The students hoped that the land they bought would be protected and not destroyed.
The students became so interested in rain forests that they decided to get a closer look at areal river. They saw alligators (短吻鳄) crocodiles. A guide took Myers and his students into the rain forest. “The monkeys were not happy that we were in their forest. They broke small branches on the trees and threw them at as.” One of the students said. “It was a great learning experience for all of us,” said Myers. This was the start of the children’s Rain Forest. This project works to save rain forest all over the world.
