例如：
She is too young to do the work.→She isn't old enough to do the work.
2.将too...to...结构转换为so...that...结构时要注意：①so...that...结构是复合句,so的后面接形容词或副词,that的后面接从句；②that后面的从句要用否定形式.例如：
She is too young to do the work.→She is so young that she can't do the work.毕竟我才上初三、只能尽力而为.补充：lz翻译不对,应为：he goes out of his way to help her./he racks his mind to help her.He is only too pleased to help her转换：he is afraid that he can't help her enough.he is so pleased that he can't help her enough.追问：你们初二时老师讲了too to可以表肯定吗 回答：下面几种情况“too...to...”表示肯定意义.1.当too后面接anxious,eager,ready等一类形容词时,“too… to…”结构表肯定意义 ：
Jenny is too ready to speak.Jenny话太多了.
I am too anxious to know the test result.我太想知道考试结果了!
2.当too前面有用于加强语气的only,all,but等词时,“too… to…”结构表肯定意义.
I am only too glad to meet you.见到你真是太高兴了.
You know but too well to hold your tongue.你深知保持沉默的妙处.
3.当too前面有not或never时,“too… to…”结构表肯定意义：（有人认为这是双重否定表示肯定）
One is never too old to learn.
It is not/never too late to mend.追问：初二老师讲的还是你自学的?还是初三讲的?回答：那个sb老师才大学毕业,怎么可能将这么详细.这是从网上找到的,不过我父母都是英语老师,问他们比较容易些.还有,我是该上初三,追问：我知道 too to 表肯定意义的用法,只是想知道表肯定时,能不能与so that,enough to的肯定式 转换 回答：有时可以,不过肯定的是,so...that..可以和.enough to进行转换.追问：你初二上学期老师详细教become,turn,grow的区别了吗?when引导的时间状语从句了吗?回答：我妈给我讲过,when引导的时间状语从句后面不能加将来时,用一般现在时表一般将来时,用一般过去时表过去将来时、grow 主要表示逐渐变化,强调变化的过程,
例：It began to grow dark.天色渐渐黑了.grow表示“逐渐变成新的状态”的含义.如：
My younger brother is growing tall．我的弟弟渐渐长高了.become通常不用来表示未来的事,而表示变化过程已经完成,用法比较正式.如：I became ill．我病倒了.turn有“成为与以前完全不同的东西”的含义.如：
The milk turned sour．牛奶变酸了.
