对于Paragraph 1，文段开头提出“if we didn’t have grass”并描述了相关场景，接着具体阐述没有草后雨天和干燥天遇到的不同麻烦，都是围绕草对人们的帮助展开，重点不是为什么需要雨、如何让草保持绿以及没有草要走裸露土地这些片面内容，所以主要讲的是草如何帮助我们。对于Paragraph 2，文段指出老鼠对人们几乎和很久以前一样是巨大威胁，接着阐述它传播疾病、吃庄稼以及吃世界上收获的一半谷物，这些都是在说明老鼠成为人类敌人的原因。

Ⅳ.Reading comprehension.
Every year some parts of rainforests disappear on the Earth. There were lots of plants and animals living in these forests many years ago. However, many of them die now. Other animals have to leave and find a new forest to make their home. We are sorry to see that some rainforests are disappearing. Why do the rainforests disappear so quickly?
The main reason is that people destroy rainforests. People cut down many trees in the rainforests every year. In the last 200 years, people have destroyed more than half of all the trees on the Earth. They used the trees to produce furniture and paper. Farmers needed to grow food and keep animals, so they turned rainforests into farms.
The drought(旱灾)is bad for rainforests too. In 2010, a big drought happened in the Amazon Rainforest. Rivers dried up and millions of plants and animals died. The drought also made the air so dry that the forest fire happened easily. Many animals lost their homes because of the fire.
It’s time to protect the rainforests. All of us should take care of the forests to make the world more beautiful.
