知识点链接:
1. But now they have less and less land to live on.但他们现在可以居住的地方越来越少。
（1）less是little 的比较级。
（2）to live on不定式短语，在此句中作land 的定语，意为“可居住的”。起形容词的作用，在英语中，动词不定式作后置定语，修饰前面的名词或代词时，他们之间构成逻辑上的动宾关系，若动词为不及物动词，要在其后加相应的介词。
（e.g） Do you have something to read?你有可读的（刊物）吗？
Would you like something to drink?你想喝点什么吗？
I need a pen to write with.我要一支笔写。（write with与pen形成逻辑上的动宾关系,with不可省。
2. They are in danger now.他们现在处于危险之中。
In danger处在危险中
3. They are the oldest type of tigers living in the world.他们是世界上存在的最古老的虎种。
现在分词短语living in the world作后置定语，放在被修饰的词的后面。
（e.g） Do you know the boy talking to our English teacher?你认识和我们英语老师谈话的那个男孩吗？
4. The plants in the countryside are more beautiful than those in the city.
Those代替的是前面提到的plants,以避免重复。若代替的是单数可数名词或不可数名词，则用that .
(e.g) The temperature in Chongqing is much higher than that inQjiang.
