转眼间，亲爱的同学们已经开始初三下学期的学习生活了。为了方便大家的英语学习与考前复习，本人对9B Unit 1的知识点进行了归纳总结，供大家在学习时参考。

get to它还有 “够到”的意思
如：I am not tall enough, so I can’t get to the apple on the tree.
二、 help sb. do sth.的用法
help sb. do sth.改為被动语态时要把do前省掉的to加回去，类似的有make，see等动词。

四、by后加上时间的用法
by意为“到……为止”,by后加时间状语有3种情况：
若后接表示将来的时间状语，则常用于一般将来时；
若后接表示过去的时间状语，则常用于过去完成时；
后加now，则常用于现在完成时。
如：It’s said that there will be more than 9 billion persons on Earth by the year 2046.

五、 too...to...的用法

六、 百分数和分数的用法
分数的表达：分子（基数词）-分母（序数词）。当分子大于1时，分母用复数。如：用英语写出：1/7=one-seventh5/6 = five-sixths
分数和百分比的后面均可以加上of +名词，后面动词的单复数取决于名词的单复数形式。
如：Three-fifth of the students are good at dancing.
Two-thirds of the Earth is covered with water.
88% of the teachers have finished their work already.
Five-sixths of the food has been eaten by the fat boy, sowe have very little food to eat.

九、 have sb. do sth的用法：

注意改为被动语态时，要把do前省掉的to加上去。
