课堂导入
Lesson 4 An exciting trip 激动人心的旅行
I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer.
He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought
an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From
there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.
我刚刚收到弟弟蒂姆的来信,他正在澳大利亚。他在那儿已经住了 6月了。蒂姆是个工程师,正在一家大公司
工作,并且已经去过澳大利亚的不少地方了。他刚买了一辆澳大利亚小汽车,现在去了澳大利亚中部的小镇艾利
斯斯普林斯。他不久还将到达达尔文去,从那里,他再飞往珀斯。我弟弟以前从未出过国,因此,他觉得这次旅
行非常激动人心。

3、数词的应用
(1). 年月日的表示:① 年份用基数词,如 2000——two thousand; 1905——nineteen 0 five

注意:
序数词应注意的几点事项:
1. 多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。如:
forty-two 42 forty-second 42
nine-hundred 900 nine-hundredth 900
2. 当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。
如:21st 21 32nd 32
3. 编了号的事物要用基数词表示顺序,但是基数词要后置。
例如: 第一课:Lesson One 第三十二页:Page 32
305 房间:Room 305 12 路公共汽车:Bas No.12
4. 序数词前一般要用定冠the,如果序数词前用 aan ,则表示“又一;再一”(没有具体范围的限制)
如:Though he had failed twicehe wanted to try a third time. 尽管他已失败了两次,他还想再试一次。
The little monkey had had three applesand he wanted to eat a fourth one.
那只小猴子已经吃了 3个苹果,他还想再吃一个。
时间表达注意:
1. 点时间,用基数词表达,后边可o’clock (可不加)。表达“几点几分”时,
o’clock
2. 表达“15 分”或“45 分”时,常用 quarter)。
3. 读法如果点不,须+past+
+to+全钟点(下个点数)”的形式。
