七年級英語第二十九單元 日常交際用語及慣用法
內容
教學目的: 日常交際用語及慣用法.
一. 教學重點難點: 一些詞彙的習慣用法.
二. 重點難點講解:
1. one 用作替代詞.
One可以用作代詞, 代替前面已經出現過的單數可數名詞, 以避免重複. 在沒有定語修飾的情況下, one不帶冠詞, 如果有定語, one就要有冠詞. 例如:
(1) You can get one.
你可以得到一個.
(2) “ Which one?” “The one under the tree.”
“哪一個?” “樹下面的那個.”
代替複數名詞時, 一般用ones 或those. 例如:
She likes the red bags, but I like the green ones.
她喜歡紅色的書包, 但是我喜歡綠色的.
2. sell 和 buy
sell是 “賣” buy是 “買”
He sells cakes.
他賣蛋糕.
I want to buy some apples.
我想買一些蘋果.
3. How much….? 多少錢?
How much is this bike?
Three hundred and sixteen yuan.
這本書多少錢?
三百一十六元.
注意, 百位數與十位數之間要用and連線.
How much還可以與不可數名詞連用, how many與可數名詞的複數形式連用, 以表示數量.
4. cheap 和dear
這兩個詞都是形容詞, cheap 表示 “便宜”, dear的意思是 “貴的”, 兩個詞在意思上互為相反. 例如:
This book is too dear, that one is cheap.
這本書太貴了, 那本便宜.
5. half
英語中的 “一半”是a half, 但如果要表示 “一半的…”, 也就是說如果後面要接一個名詞的時候, 則多用half a +名詞, 例如:
half a day/week/year
半天/半個星期/半年
6. go shopping 去買東西
這裡的shopping是動詞shop的-ing形式, go + 動詞的-ing形式表示去做某事.例如:
go swimming 去游泳
go fishing 去釣魚
go boating 去划船
go dancing 去跳舞
7. You can help me carry the things.
你可以幫助我拿東西.
Help sb. (to) do sth. 這一結構中, 不定式do sth.前可帶to, 或省略. help sb, 後還可以接with介詞短語. 例如:
(1) He helps me (to) go over my lessons.
= He helps me with my lessons.
他幫助我複習功課.
(2) I help him to carry the water.
我幫助他去打水.
8. I want to buy some good food for supper this evening.
我要為今晚的晚餐買些好食品.
this evening是 “今晚” 的意思. this 可以用來指當前的單位時間, that可以用來指已過去的單位時間. 用this, that修飾時間名詞時, 前面不能再用介詞in或on, 例如:
this/that morning 今天/那天早上
this/that year 今年/那一年
this/that time 這一次/那一次
9. Don’t we have any food for supper?
我們連一點做晚飯的食品都沒有了嗎?
這是一個否定疑問句, 其構成方式是把助動詞(情態動詞或be動詞)與not一起放在主語前, 並用縮寫形式, 不能分開寫. 否定疑問句主要用來表示說話人的懷疑, 驚奇等感情, 例如:
(1) Aren’t you Tom?
你不是湯姆嗎?
(2) Can't you see it?
你看不見嗎?
10. 介詞from的基本用法.

(3) The teacher often works from eight to four.

11. on the/one’s way to …

這裡way是名詞, 表示 “路途”, to 是介詞, 表示方向或目的地, 如果後面接的是副詞, 則要省略to. 例如:

(2) I often see a child on my way to school.
