Unit1重要知识点讲解人教版九年级英语
Unit1 How can we become good learners?重要知识点讲解Section A_Grammar Focus_Section B_综合Section A一、介词by的用法By working with friends.通过和朋友合作。
[点拨]"by"是介词，意为“通过，靠”；此处表示方法、手段，后接名词或代词；接动词时，须用动名词形式。
可用来回答how引导的特殊疑问句。

2）沿着，经由to enter by the door 由门进去3）由于by mistake 由于差错；错误地4）被，由some articles written by Lu Xun 一些由鲁迅写的文章5）表示相（乘）除（以计算面积）a room 5m by 4m 一个长五米宽四米的房间6）逐一；连续one by one 一个接一个二、too...to结构It's too hard to understand the spoken English.口语太难了，不能理解。
[点拨]“too + 形容词/副词+to+动词原形”意为“太...而不能...”；该句型用于肯定句，但表示否定的意义。
too…to…前面有never，not，only，but等词时，或出现too …not to do的双重否定时，否定词与不定式中的否定意义结合起来构成了肯定意义。
如：It’s never too old to learn.活到老，学到老。
三、so...that结构1.The teacher spoke so quickly that I did not understand her most of the time.老师说得如此快，以致于大多数时间我不能理解她说的。
