一、如何询问价格
询问价格的句型为:How much is/are …?
1.“How much is …?”常用来询问单数名词或不可数名词的价格,对此问句进行回答时常用句型为:“It’s+价格”。eg:
—How much is the T-shirt?这件T-恤衫多少钱?
—It’s 68 yuan.68元。
—How much is the milk?牛奶多少钱?
—It’s 109 yuan.109元。
2.“How much are …?”常用来询问复数名词的价格,对此问句进行回答时常用句型为:“They’re+价格”。eg:
—How much are these shoes?这双鞋子多少钱?
—They are 18 dollars.18美元。
—How much are those dresses?那些连衣裙多少钱?
—They’re 80 yuan.80元。
【拓展】
询问物品的价格还可以用句型“What’s the price of …?”。使用这一句型时,不管所询问的物品是单数还是复数,be动词都用is,其答语都用“It’s …”。eg:
—What’s the price of that book?那本书多少钱?
—It’s fifteen yuan.15元。
—What’s the price of the books?那些书多少钱?
—It’s fifty yuan.50元。
二、基数词的记忆规则及用法
1.基数词的记忆规则
(1)0—12这13个数字独立成词,要单独记忆。它们分别是:zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve。
(2)13—19都是以“个位数+teen”构成,fourteen, sixteen, seventeen, nineteen为个位数直接加-teen构成;thirteen, fifteen, eighteen的拼写需特殊记忆。
(3)20—90整十位数的基数词由相应的个位数字后加-ty构成。sixty, seventy, ninety为个位数直接加-ty构成;twenty, thirty, forty, fifty, eighty的拼写需特殊记忆。
(4)21—99的两位数的表达是整十位数加个位数,中间加上连字符“-”。eg:
twenty-one,forty-two, seventy-eight
(5)100可以写成a hundred或one hundred。一般hundred都不用复数形式。eg:
two hundred, three hundred
2.基数词的用法
(1)表示年龄,基数词放在years old之前。eg:
He is twelve years old.他十二岁。
(2)用来表示人或物的数量,放在名词之前。eg:
I have three balls.我有三个球。
(3)表示顺序、编号等,放在名词之后。eg:
I’m in Class Four.我在四班。
(4)用来计算。eg:
Two and six is eight.二加六等于八。
—What’s forty and twenty?40加20等于多少?
—It’s sixty.等于60。
(5)基数词作主语时,谓语动词用单数形式。eg:
Six and ninety is ninety-six.6加90等于96。单元语法强化训练
