Rainforests are very important to us. It is necessary for us to protect them very well. First, we should make people know about the importance of protecting them. Then ask people not to cut down the trees without plans. For us, we should do something as possible as we can. When we have meals, we mustn’t use chopsticks for only once. In the life, use less paper and be sure not to waste it.

2.I think the sheep are the nicest of all.
我觉得所有动物中羊是最可爱的。
the nicest 最喜欢，of all是of all the animals的省略，也是最高级的标志，详情见语法部分。
例： He is the tallest of all.他是所有人中最高的。
sheep 羊，单复数同形。
例： The sheep is/are eating grass. 那只/些羊正在吃草。
3.As we know, they are both important to us.

be important to sb. 对sb.重要
例: The plants are very important to people. 植物对人们很重要。
4. Thousands and thousands of animals live in rain forests.
数以百万计的动物生活在热带雨林中。
thousands of 意为“好几千，成千上万。“是一个大概的数目。表示大概数目时，thousand/ hundred/ million/ billion 后要变复数，前面可加many等数目模糊的修饰词，而且必须搭配of所有格。而表示一个确切的数目时，thousand/ hundred/ million/ billion后不能变复数，前面必须加数词，不能搭配of所有格。
例： There are thousands of students learning in the school.有好几千学生在这所学校学习。
There are two thousand workers in the factory.这家工厂有两千工人。
注意：several hundred/thousand/million/billion
several（几个）相当于具体数字
5. But now, rainforests are becoming smaller and smaller, so we should protect them.
但是，现在热带雨林正变得越来越小，我们应当保护它们。
smaller and smaller越来越小，形容词（或副词）的比较级+and+形容词（或副词）的比较级表示“越来越......”。
例： She grows taller and taller.
【拓展】
多音节形容词（或副词）表示“越来越......”要用“more and more +多音节形容词（或副词）的原级”来表示。
例： Our country is becoming more and more beautiful.
6. They feed on bamboo. 它们以竹子为食。
feed作“喂养”讲时，后面常接on，to，with等介词，其用法如下
feed......on 给......喂....../feed on sth 以……为食
例： We feed the monkey on apples.我们给猴子喂苹果。
feed......to把......喂给，向......供给食料/ 动力
例： I feed vegetables to my rabbit.我拿蔬菜喂兔子。
feed......with 向......提供，用......满足。

Let me share something with you about the mobile payment.
Hello, everyone. Let me share something with you about the mobile payment. As we know, the mobile payment is now becoming more and more popular among the young and the old in China. As for my parents, they hardly ever use paper money to pay for things. Instead, they always pay with apps on their mobile phones. They use both Alipay and WeChat pay because these two apps are easy to use. I like the mobile payment for two reasons. First, it is easy to use. You just need to enter Alipay and WeChat pay, scan the QR code, enter your password and that’s it. Second, it makes our lives more convenient. We don’t have to carry a lot of paper money when we want to buy something. What’s more, we can pay for things anytime and anywhere.That’s all, thank you for listening.
