句式精讲
1. It’s/was + adj. + to do sth.
It is/was + adj. + to do sth.意为“做某事是……的”，to do sth.为句子的真正的主语，而it为形式主语，形式主语不能用别的词来代替，句中可在形容词后加for sb.，意为“对于某人来说，做某事是……的”。例如：
It’s important for us to learn a foreign language.
对我们来说，学习一门外语是相当重要的。
It’s necessary for us to eat more fruit and vegetables.
对我们来说，多吃蔬菜和水果是必要的。
【拓展】
这个句型中的for sb.有时也可以用of sb. 二者意义有区别：
（1）在It’s + adj. + for sb. to do sth. 中，for sb.意为“对某人来说”，句中的形容词是用来说明to do sth.的，形式主语只能用it。例如：
It’s necessary for the students to do some housework.
对于学生们来说，做些家务是十分必要的。
（2）在It’s + adj. + of sb. to do sth. 中of sb. 意为“某人……”，句中形容词可与逻辑主语sb. 构成系表结构，即形容词是用来说明或形容sb.（某人）的。例如：
It’s very kind of you to help us. 你能帮助我们真是太好了。
2. The baby panda is not old enough to eat bamboo.
（1）enough…to do sth. “有足够的……做某事”。例如：
I don’t have enough time to eat lunch. 我没有足够的时间吃午饭。
（2）…enough to do…可以同too…to…或so…that…结构互相转换。例如：
He isn’t old enough to go to school. = He is too young to go to school.
= He is so young that he can’t go to school. 他太小而不能上学。
【拓展】
（1）enough是形容词，意为“充足的，充分的，足够的”，可作表语或定语，作定语时，可放在名词的前面或后面。例如：
The food is enough for the trip. 用于这次旅行的食物足够了。
I have enough time to watch TV. 我有足够的时间看电视。
（2）enough还可作副词，意为“足够的”，这时enough需放在所修饰的形容词或副词后面。例如：
The young man is strong enough to carry the heavy bag.
那个年轻人足够强壮能搬动重包。
3. The baby panda is too young to eat bamboo.
句型 too＋形容词/副词原形＋to do something的意思是“太……而不能……”，这个句型可以和not＋形容词/副词原形＋enough to do或 so＋形容词/副词原形＋that从句相互转换。
You are too young to go to school.
= You are not old enough to go to school.
= You are so young that you can't go to school.
你太小了，还不能上学。
4. The fish will die if the river is polluted.
　本句中的if意为“如果”，引导条件状语从句。在条件状语从句中，如果主句为一般将来时态，if引导的从句需要用一般现在时态。例如：
　 I’ll tell him if I meet him. 如果我碰到他，我会告诉他。
　 If it doesn’t rain tomorrow，we’ll go to the park.
　 如果明天不下雨，我们就去公园。
【拓展】
　if 意为“是否”时，引导宾语从句，有时可以与whether换用。 例如：
　I don’t know if my mother will come back next week.
　我不知道我妈妈下周是否回来。
5. In September 1987, one of the birds went missing.
one of…意为“……中的一个”或“……之一”，后接复数名词，当名词前有形容词修饰时，形容词应用其最高级形式。one of…作主语时，应看成单数。例如：
One of the girls is my sister. 这群女孩当中有一个是我的妹妹。
Mike is one of the tallest students in our class.
迈克是我们班最高的学生之一。
Miss Li is one of the most popular teachers in our school.
