一、教法建议
【抛砖引玉】
单元双基学习目标
Ⅰ. 词汇学习
rock , hardly , low , rise , famous , photograph , at the foot of , at all , fly over , a line of mountains , ask for
Ⅱ. 句型学习

Though much of its land is sand , it grows a lot of fruit .
Hardly any .

【指点迷津】
单元重点词汇点拨
1 . take 耗费 ( 时间 ) ；需要 ( 多少时间 )
It may take me several weeks to get back .
It will take them three hours to do this work .
This work will take them three hours .
〖点拨〗take 的过去式took，过去分词 taken。It takes sb . some time to do sth . 某人花费多少时间做某事。
2 . rock 岩石；大石头
They found a good place in the rocks .
〖点拨〗rock 主要指巨石、暗礁，stone 主要指小石块。
3 . hardly 几乎不；简直不
I\'m so tired that I can hardly walk .
That is hardly possible .
There is hardly a cloud in the sky .
〖点拨〗hardly 作“简直不”讲时，多和 can 连用，hardly 后面可以接用 when 引导的从句，意思是“一……就……”。如：He had hardly walked into the classroom when it began to rain cats and dogs . 他刚一进教室，天就下起了大雨。
4 . sky 天空
There were no clouds in the sky .
〖点拨〗sky 通常用作单数，与定冠词连用。如有形容词修饰时，可与不定冠词连用。
a blue sky 蔚蓝的天空。in the sky在天空。
5 . rise 上升，上涨
The sun rises in the east .
After the heavy rain the river will rise .
Prices continue to rise .
〖点拨〗rise 的过去式是rose，过去分词为 risen。rise 是不及物动词，表示的是自然界中，日、月、水位、物价等的自然上升。
6 . grass 草，草地
Sheep live on grass .
Keep off the grass ! 请勿践踏草地 ！
〖点拨〗grass常作不可数名词用。a leaf of grass 一片草叶。
7 . famous 著名的
