重点句式——多维剖析
1.代词that
【教材原句】One of the most wonderful migrations in nature is that of the North American monarch butterfly.
自然界最奇妙的迁徙之一是北美黑脉金斑蝶的迁徙。
句中的that在此处是替代词,相当于the migration。替代词的使用往往是为了避免与上文出现的名词重复。that既可替代可数名词,又可替代不可数名词,还可替代前面整句话的内容,不能用冠词或形容词修饰。其他替代词的用法:
(1)one只替代可数名词的人或物,一般指同名异物,不能代指前面整句话的意思,可用冠词或形容词来修饰,表示特指时一般加定冠词the。
(2)ones代指上文出现的或已知的复数名词,也是类指,可以用冠词或形容词来修饰。
(3)it指上文提到的同名同物,还可指代婴儿或性别不详者,能代指前面整句话的内容,不能用冠词或形容词修饰。
(4)those是that的复数形式,指“那些”,表示特指,代指提到的或已知的复数名词。

我们对这种可爱的生物了解得越多,它在未来相当长的一段时间里存活和栖息在自然界的机会就越大。
“the+比较级...,the+比较级...”结构的具体用法如下:
(1)意为“越……,就越……”,主从句的两个谓语是同时进行的,表示后面一方随前面一方程度的变化而变化。
(2)从结构上看,第一个“the+比较级”是表示条件的状语从句(通常用一般现在时或一般过去时;表示将来意义时,从句用一般现在时表示将来);第二个“the+比较级”是主句(通常使用一般将来时或过去将来时,有时也可用一般现在时或一般过去时)。
