Section C 1a
Rainforests
Rainforests are thick forests in the hot parts of the world. It rains a lot and the ground is always wet. It's always dark and hot in rainforests. Rainforests cover 6%of the earth's surface.They provide places to live for thousands of plants and animals found nowhere else on Earth. There are lots of tall trees and other different kinds of plants. Thousands and thousands of animals live in rainforests. Many of them live in the trees over 30 meters from the ground.
Rainforests are very important to us. They are the lungs of the earth. The plants in the forests help to make the air fresher and cleaner. They also help to hold the water when it rains and keep the water cycling. They play an important part in controlling the climate.Rainforests also help to keep the beauty of nature. Without rainforests,many beautiful plants and animals would die out. Rainforests give us wood, food,fruit, medicine, and many more useful things. We need rainforests for many reasons.But now, rainforests are becoming smaller and smaller, so we should protect them.
雨林
雨林是生长在世界上热带地区的茂盛森林。降雨量很多,地面通常都是湿的。雨林中又热又暗。
雨林覆盖了地球表面6%的面积。它们为无数地球上其它地方没有的动植物提供了栖息地。那里有很多高大的树木和其他不同的植物。有无数动物居住在雨林中。它们生活在30多米高的树上。
雨林对我们很重要。它们是地球的肺。雨林中的植物让空气更新鲜更洁净。下雨时还能储存水分,促进水循环。它们在控制气候方面扮演着重要的角色。雨林还能保存自然美。如果没有雨林,很多漂亮的动植物都会灭绝。雨林为我们提供木材、食物、水果、药材和很多其他有用的东西。有很多原因让我们离不开雨林。但是现在,雨林变得越来越少,我们必须要保护它们。
Section D
处于危险中的动物
熊猫生活在中国西南部的森林和山里。它们以陷阱为食,但现在它们只能依靠越来越少的土地生活。所以熊猫的数量越来越少。
世界上最重的动物不是清洁动物。它们是蓝鲸。它们是最大的,但它们以最美丽的海洋动物为食。现在他们正处于危险之中,因为有些人把他们的海洋弄得脏兮兮的,而另一些人则为了他们的肉而捕杀他们。
中国老虎生活在中国南方。他们现在也处于危险之中。它们是世界上最古老的老虎,它们吃小动物。有些人杀老虎是为了它们的皮毛和骨头。
五、重点语言点

(2)不规则变化:child---children;foot---feet,tooth---teeth牙齿;goose---geese 鹅
mouse---mice老鼠; man---men; woman---women
注意:与 man 和 woman构成的合成词,其复数形式也是 -men 和-women。如:
an Englishman,two Englishmen. 但German(德国人)不是合成词,故复数形式为Germans;
(3)只有复数形式的名词: trousers裤子,pants裤子,shorts短裤 glasses眼镜,
2. 形容词和副词的比较级前可用much, a little, even, far 来修饰,但不能用more, very。如:

5. In fact, water makes up the largest part of the human body.
make up 组成,be made up of 由… 组成, 如:Our team is made up of 11 players.

be + in +名词,用来表示“处于…之中”如:be in danger, be in trouble, be in health.
3. The plants in Picture One are more beautiful than those in Picture Two.
those 在此指代“the plants”。包含比较级的句子必须是同类事物才能比较,为了避免重复,用that(代单数名词)或 those (代复数名词) 代替前面出现的词或短语:

解析:形容词的最高级前面要加the, 序数词前一般也加the, 表“第几”,如:the first lesson.
但序数词前也可用a, 表“再第几次”,如:He had tried for six times, but he failed, then he tried a seventh time. (他再试了第七次), 故答案为:A
