Section B（第三、四课时）
重点直击 导析
重点1 基数词的表示方法。
英语中，表示数目的词叫基数词。
1.one~twelve（1~12）的拼写和读音各不相同，无规律可循，应逐一记忆。
2.thirteen~nineteen（13~19）表示“十几”，在个位数词后加后缀-teen，读作/ti:n/，单词有两个重音。要特别注意thirteen（13）, fifteen（15）和 eighteen（18）的拼写。
3.twenty,thirty...ninety（20,30...90）表示“几十”，这些词都以-ty结尾。20、30、40、50、80的拼写要注意，分别是twenty, thirty, forty, fifty, eighty； 60、70、90分别是由six，seven, nine后加-ty构成。
4.表示“几十几”，就用“几十”加连字符再加“几”。例如：表示21就用twenty（20）加连字符再加one（1），即twenty-one。再如thirty-six
（36）, fifty-eight（58）, sixty-seven（67）, seventy-five（75）, eighty-nine
（89）, ninety-eight（98）。
5.hundred意为“百”。hundred 前面可以加上数字，表示“几百”，不论数字多大，hundred一定不能加-s。
6.表示“数以百计的”用“hundreds of+复数名词或代词宾格”。在此结构中，hundreds of前面不能加数词，hundred一定要用复数形式。例如：
hundreds of students 成百上千的学生
针对训练
（1）—How many days are there in February（二月）？
—There are ________.( )
A
A.twenty-eight B.twenties-eight C.twenty-eighteen
（2）Seven and eight is ________.( )
C
A.fifty B.fiveteen C.fifteen
重点2 大甩卖用语。
Come and buy your clothes at our great sale!在我们大甩卖之际来购买衣服吧!
（1）该句是祈使句。祈使句以动词原形开头，表示建议、请求或命令等。例如：
Come to the meeting before eight. 八点之前来开会。
Wait for me in the classroom. 在教室等我。
Don’t be late for school. 上学别迟到。
（2）句中at表示“以……的价格”。例如：
We have socks in all colors at $2 each!我们所有颜色的袜子都卖
2美元一双!
（3）sale是sell的名词形式，意为“买卖、销售”。sale还可作“大甩卖，清仓大减价”讲。例如：a sale price 廉价; on sale 出售、特价销售; for sale 待售。
（4）clothes 意为“衣服，服装”，常用复数形式，不用单数。例如：
The clothes are new.这些衣服是新的。
针对训练
（1）________ to my school and have a look.( )
C
A.Coming B.Comes C.Come
（2）We have all the things in the store ________ two yuan.( )
B
A.for B.at C.of
（3）Mr. Smith’s Clothes Store are ________ sale today.( )
A
A.on B.for C.at
重点3 price的用法。
We sell all our clothes at very good prices. 我们以很优惠的价格售卖所有的衣服。
price是名词，意为“价格; 价钱”。问商品的价钱是多少可以说：“What’s the price of... ”，可以与“How much is/are... ”互换。
一些与price有关的短语如下：
at a very good price 以很低的价格
at a good price 价格合理
at a high/low price 以高/低价
at a fair price 以公平的价格
针对训练
How much is this notebook （同义句转换）
_______ the ______ of this notebook
What’s
price
重点4 pair的用法。
I need a pair of black shoes for school. 我需要一双黑色的鞋上学穿。
a pair of意为“一双；一副”。有很多物品是由两部分一起构成的，如：shorts, trousers, glasses, shoes, socks, gloves（手套）等。这些词在英语中经常用pair来计数。例如：a pair of shoes（一双鞋）; two pairs of trousers（两条裤子）等。这样的短语作句子主语时，谓语的单复数取决于pair，如果pair 是复数时，谓语用复数形式; 如果pair是单数，谓语就用第三人称单数形式。例如：
This pair of glasses looks very nice. 这副眼镜看起来很好看。
Three pairs of socks are ten yuan. 三双袜子10元。
针对训练
（1）This pair of trousers ________ twenty dollars.( )
A
A.is B.are C.sells
（2）I want three ________ of socks.( )
B
A.pair B.pairs C.pieces
重点5 for的用法。
For boys, we have black trousers for only $22. 对于男孩, 我们有黑色的长裤，只卖22美元。
该句中有两个for，但它们的意思却各不相同。
（1）for boys意为“对于男孩; 适于男孩的”，for在此处意为“适合于”。例如：
These are sweaters for children. 这些毛衣是适合小孩儿穿的。
（2）for only $22意为“只卖22美元”。for在此处意为“以……为代价; 以……交换”。例如：
He sells his computer for 50 dollars. 他的电脑售价50美元。
Two dollars for one pair and three dollars for two pairs. 两美元一双，三美元两双。
针对训练

导析导练
重点直击 导析
重点1 how much的用法。
—How much are these socks 这些袜子多少钱
—They’re two dollars.两美元。
Section A
how much用于询问物品的价格，意为“多少钱”，其句式为“How much is/are +名词（短语） ”。当名词（短语）是不可数名词或可数名词单数时用is; 当名词（短语）是可数名词复数时用are。例如：
—How much is the milk 这牛奶多少钱
—It’s ten dollars. 10美元。
—How much is this dictionary 这本词典多少钱
—It’s twenty dollars. 20美元。
—How much are the black shoes 这双黑鞋多少钱
—They’re eighty dollars. 80美元。
（1）询问和回答价格的其他方式: “What’s the price of + sth. ” “ It’s+金额.”。例如:
—What’s the price of the hat 这顶帽子多少钱
—It’s ten yuan. 10块钱。
—What’s the price of these socks 这些袜子多少钱
—It’s nine dollars. 9美元。
（2）how much还可以用来询问数量的多少，但后面要跟不可数名词。例如：
—How much bread do you need 你要多少面包
—Two pieces.两片。
针对训练
（1）—How much ________ the trousers
—Thirty yuan.( )
A
A.are B.is C.be
（2）How much ________ this pair of socks ( )
B
A.are B.is C.does
重点2 相关货币及符号。
dollar是美国、加拿大、澳大利亚等国家的货币单位，符号为$，是个可数名词，有复数形式。常用的货币单位还有pound（英镑，符号为 ，也有复数形式），yuan是中国货币单位，没有复数形式，符号为 。
针对训练
（1）This sweater is twenty ___.
B
A.dollar B.dollars C.pound
（2）—How much is the T-shirt
—It’s twenty-five ___.
A
A.yuan B.pound C.dollar
重点3 need的用法。
I need a sweater for school. 我需要一件毛衣上学穿。
在这句话中，need是实义动词，意为“需要”。need常用于以下句式。
（1）“need +某物”，表示“需要某物”。例如：
I need a lot of storybooks.我需要很多故事书。
（2）“need +to do sth.”表示“需要做某事”。例如：
You need to put on your sweater.你需要穿上毛衣。
need还可以做情态动词用。need做情态动词时，相对简单，同其他情态动词一样，无时
态变化，其后跟动词原形。否定句结构为“主语+needn’t+动词原形+其他.”; 疑问句结构为“Need+主语+动词原形+其他？”。
You needn’t finish this work today. 你今天不必完成这项工作。
Need I buy a hat for you 我有必要给你买个帽子吗？
针对训练
（1）Lingling ________ a pair of new shoes.( )
B
A.need B.needs C.to need
（2）What do you need ________ ( )
C
A.buy B.buys C.to buy
重点4 look作系动词的用法。
It looks nice. 它看起来很漂亮。
该句是主系表结构。在该句中look是连系动词，意为“看起来”，后面要接形容词作表语。类似用法的动词还有sound,feel等。例如:
That sounds great. 那听起来太好了。
The skirt looks nice on you. 这条裙子穿在你身上很漂亮。
针对训练
