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

I like writing to my penfriend , but it takes a lot of time .

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

Hardly any .

None at all .

Ⅲ. 交际英语

谈论某一国家的地理位置及气候、特征。

【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

The town is famous for its hot springs .

He is a famous man .

〖点拨〗be famous for 以……而著名。be famous as 作为……而出名。

My uncle is famous for his songs .

Her sister is famous as a singer .

单元词组思维运用

1 . neither of 两者皆不

Neither of my parents enjoys good health . 我父母的身体都不健康。

〖说明〗①neither of 只表示“两个人或物都不”，不能用来表示两个以上的人或物。谓语动词用单数。若表示两个以上的人或物，就得用 none , not one , not any .

②both of 则表示“两者都”，either of 则表示“两者中任一”，如：

Both of them have come . 他们俩都来了。

Neither of them has come . 他们俩都没来。

Either of them has come . 他们俩全都来了。

〖说明〗both of 着重指整体“两者都”，either 虽然也有“两者都”之意，但强调“两者中的任何一个”。故：both of 作主语时，谓语动词用复数。either of 作主语时，谓语动词用单数。作形容词时，both 修饰复数名词，either 修饰单数名词。neither 作形容词，也是修饰单数名词。如：

You can sit on either of the end of the boat .

Both answers are correct . 两个答案都对。

Either answer is correct . 两个 ( 中的任何一个 ) 答案都对。

Neither answer is correct . 两个答案都不对。

2 . at first 起初，开始时

At first the baby was happy . Half an hour later she began to cry .

at last 最后，终于／at the beginning of 起初

At last he had an idea . 终于，他有了主意。

I found a job at the beginning of last month . 上月初我找到一份工作。

3 . climb up 攀登，爬上

There he gets out of the lift and climbs up to the fifteenth floor on foot .

4 . at the foot of 在……的底部 ( 脚下 )

There is a small river at the foot of the hill .

5 . go down 下去， ( 日，月等 ) 落下

The sun has gone down .

The wind has gone down a little .

6 . have a great time = enjoy oneself过得愉快极了

I had a great time during the holidays .

—Did you have a great time at her birthday party ?
