8. But we cut down millions of trees every year.
millions of 大量的，数以百万计的。
当表示一个笼统概念（数量多、数量大）时，hundred, thousand, million, billion 等词常用复数形式，且与介词of连用修饰名词。
hundred, thousand, million, billion 等前面有具体的数词时，其后不加s,也不带介词of.
millions of animals eight hundred students
because of + 名词：因为…

the number of … … 的数量
a number of … … 许多，大量
语法
1. 现在进行时
现在进行时由“be动词(am / is / are) +动词-ing”构成，表示现在(指说话人说话时)或者现阶段正在进行或发生的动作，往往与 now/at the moment/right now等时间状语连用。有时，Listen! / Look! / Don’t talk! 等祈使句后面往往会跟一个现在进行时的句子。
2. 句式变换
否定句： 主语+ be (am/is/ are) + not +动词-ing。
一般疑问句：Be (Am/Is/Are) + 主语 + 动词-ing。
特殊疑问句： 特殊疑问词(What/When/Where…) + be (am/is/are) + 主语 + 动词-ing。
3. 动词变现在分词的规则：
a. 动词结尾直接加ing; sleep---sleeping
b. 以不发音的e 结尾的词去掉e 再加ing; take---taking
c. 重读闭音节结尾，以辅音字母加原因字母结尾的词，要双写最后一个字母再加ing
swim—swimming run—running dig—digging,
类似的词还有： begin cut dig hit let put run set shut sit win get stop prefer travel beg drip drop fit hug plan rob stir rub whip regret 等
4. 部分动词(短暂性动词、感官动词、情感类动词)只用于一般现在时，不用于现在进行时：believe hear like prefer smell understand hate know love see taste want .
作文
1、How to save trees
Trees are very important to us, so we should try to protect them. How to save trees First, we should plant more trees and stop cutting down trees. After that, we can go to work by bike or on foot instead of driving cars. Then we can try to send e-mails instead of paper letters. At last, we should use both sides of every piece of paper. If we start now, we can save millions of trees.
