Language pints
1.If the rivers are plluted, farmers can't use the water fr their crps.(1) pllute是动词，意为“污染”。例：All thse waste prducts are plluting the river.所有那些废弃物正在污染这条河流。(2)use sth.fr (ding) sth.用某物做某事，相当于use sth.t d sth.。例：He ften uses the radi fr studying English.＝He ften uses the radi t study English.他常用收音机学习英语。
2.They use s much il and cause pllutin as well.
(1)s much意为“这么多”，修饰不可数名词。例：There is s much water in the cean.海里有太多水。(2)il为不可数名词，意为“石油”。例：Oil is very imprtant in ur daily life.石油在我们的日常生活中很重要。(3)cause vt.引起；引发；造成。它多指造成不好的事情发生。例：D yu knw what caused the accident？你知道是什么造成了这起事故吗？
辨析 as well、als、t与either的区别四者都意为“也”，但用法不同。①as well一般不用于否定句，通常放在肯定句或疑问句末，其前不加逗号。例：I write my wn sngs and I play the guitar as well.我自己写歌，我也弹吉他。②als比t正式一些，语气较重，只用于肯定句中，通常位于be动词、助动词、情态动词之后，实义动词之前。例：She is als angry with yu.她也生你的气。③t语气较轻，多用于口语中，放在肯定句或疑问句句末。例：He is a philspher and a pet t.他是哲学家，也是诗人。④either用于否定句，放在句末。例：If yu d nt g，I shall nt g either.如果你不去，那么我也不去。
3.It's n use talking abut things we can't d.
use在这里作名词，意为“用处”。It's n use ding sth.是固定句型，意为“做某事无用”。其中it是形式主语，真正的主语是后面的动名词短语。例：It's n use blaming thers fr yur mistake.因为你的错误责备其他人是没有用的。
4.Students at a green schl als learn ways t save energy and recycle at hme.
(1)ways t d sth.意为“做某事的方法”，相当于a way t d sth.。way或ways后也可跟f ding sth.作定语。例：They are trying t find ways t prevent the disease.他们正设法寻找预防这种疾病的方法。(2)recycle v．回收利用，再使用(废品)。它既可用作及物动词，也可用作不及物动词。例：It's useful t recycle waste paper.回收利用废纸很有用。
5.If everyne starts t d smething，the wrld will be saved.
本句是含有if引导的条件状语从句的主从复合句。在含有if条件状语从句的复合句中，如果主句是一般将来时，从句则用一般现在时表示将来。例：If it snws tmrrw，we will make a snwman.如果明天下雪，我们将堆雪人。
