问:look, watch, see三个词都有“看”的意思,请您讲讲它们之间的区别好吗?
答:好的!look意为“看;瞧”,指“集中注意力看;有意识地看”,主要强调“看”的动作,常与at连用;watch意为“观看;注视”,常用来表示“看电视;看球赛”等;see意为“看见;看到”,强调“看”的结果。例如:
Look at the butterflies. Theyre so nice. 看这些蝴蝶,它们多漂亮啊。
I often watch soccer matches on TV. 我经常在电视上看足球比赛。
I can see a bird in the tree. 我能看见一只鸟在树上。
问:how many 与how much都是用来提问“多少”的,那么两者有何区别呢?
答:how many与how much都意为“多少”,均用于特殊疑问句的句首,但它们的用法有所不同。how many用在复数名词前,当双方都知道是什么时,how many之后的名词也可以省略。例如:
How many rooms are there in your home? 你家有多少个房间?
—How many (apples) do you want? 你要多少(苹果)?
—Two. 两个。
how much用在不可数名词前,也可用来询问价格或运算结果。例如:
How much bread do you need? 你需要多少面包?
How much is the computer? 这台电脑多少钱?
How much is two and three? 2加3等于多少?
问:Ill take it. 和Ill take the socks! 这两个句子中take意为“购买”,但是take还含有“拿走;带走”的意思,究竟以哪个意思为准?
答:take可以表示“拿走;带走”,但它也有“购买”的意思。Ill take it.和Ill take the socks! 这两个句子常出现在营业员与顾客的对话中。take多指“拿走;带走”,但在买东西时,当顾客准备买下某物时常说Ill take ..., 意为“我要买……”。例如:
Ill take this hat. 我要买这顶帽子。
Take it away, please. 请把它拿走。
问:表示“购买”时,能否用buy来替换take?
答:虽然take和buy都可以表示“购买”这个意思,但是在口语中,当某人决定买某商品时,经常用take而很少用buy。如果用buy,虽然意思没错,但会显得你的英语不地道。例如:
—How much is this pair of pants? 这条裤子多少钱?
—They are 50 dollars. 五十美元。
—OK. Ill take them. 好的,我将买下。
问:本单元学习了购物用语,可我对价格的询问方式还不是很清楚,您可以帮我归纳一下吗?
答:可以。对价格进行询问时,我们常用到How much is / are ...?这一句型。如果询问表示单数意义商品的价格,用How much is...?如果询问表示复数意义商品的价格,用How much are ...?例如:
How much is your sweater? 你的毛衣多少钱?
How much are these hats? 这些帽子多少钱?
对价格进行询问时,还有另外一种表达方式:Whats the price of ...?使用这一句型时,无论被询问的商品是单数还是复数,be动词都用is,不能用are。例如:
Whats the price of the book? 这本书多少钱?
Whats the price of these books? 这些书多少钱?
问:基数词的构成有什么规律可循吗?如何才能轻松掌握它们呢?
答:只要记住下面的口诀,相信你就会轻松牢记基数词的。
基数词不难记,找出规律很容易:
零至十二各相异,一个一个单独记;
后加-teen变十几,thirteen, fifteen看仔细,
eighteen更要准确记,其中只有一个t;
二十至九十加-ty;twenty却是很奇怪,
forty本身也不乖,跟着也把规则坏,
thirty, fifty更厉害,和eighty一起搞例外;
十位后面个位倚,表示数字“几十几”,
排列顺序不费力,连字符号莫丢弃;
要表“几百几十几”,and常把百、十系,
还有一项需注意,“几百”后别把-s立;
巧学妙记加练习,hundred就是你的好成绩。
问:英语中表示“感谢”的使用场合很多,怎样才能对它们灵活运用,让别人刮目相看?
答:Thank you.是表示“感谢”最普通的用语。它适用的范围很广:
1. 感谢对方对你的帮助。例如:
Thank you for your help. 谢谢你帮了我的忙。
2. 应答别人的赞扬、祝贺等。例如:
—Your bag is lovely. 你的书包很可爱。
—Thank you. 谢谢。
—Happy Teachers Day! Mr Li. 李老师,教师节快乐!
—Thank you. 谢谢。
3. 表示接受对方的提议。例如:
—Have a drink of water. 喝点水吧。
—Thank you. 谢谢。
4. 表示婉言拒绝对方的提议。例如:
—Would you like a cup of milk? 来杯牛奶怎么样?
—No, thank you. (或No, thanks.) 不,谢谢。
5. 表示接受对方的请求。例如:
—Please remember me to your friend. 请代我向您的朋友问好。
—Thank you (或Thanks), I will. 好的,我一定代你问候。(不宜译成“谢谢”。)
6. 表示有人向你问候时的答语。例如:
—Hello, how are you today? 喂,你今天好吗?
—Very well, thank you. 很好,谢谢。
7. 表示自己的演说终了时的结尾语。例如:
Thats all I want to say. Thank you. 我要说的就是这些,谢谢诸位。
8. 应答别人的提醒或告诫。例如:
—Be careful! 当心点!
—Thank you. 谢谢提醒。
