fill... with... 用... 把...装满 ...be filled with... ... 被...装满（被动语态）相当于be full of
Large enough to do sth 足够大能做某事 ，形容词或副词放在enough 前面
In the bottom of... 在... 的底部
dust storm 沙尘暴
For sure 肯定地，当然，确实如此 be sure to do sth 一定做某事 be sure of/ about 对某事有信心，有把握
Ms. Liu told us the wind blows the dirt and the sand here from the north. 本句是一个宾语从句，从句表达的是客观事实用一般现在时态
Nothing can stop the wind because there are not many trees left. 本句是原因状语从句，“left”的意思是“剩余的”
Remember to do sth 记得去做某事 remember doing sth 记得做过某事， 用法同forget
A way to do sth 做某事的一种方法

八、教学反思
本节课的内容比较多，主要是种树的基本步骤，并且出现的从句比较多，对于学生来说学习起来相对难于理解和掌握。因此，老师在上课的过程中要讲解到位，让学生充分的读文章，从而形成语感并能够深刻的理解文章中的句子。
