教学目标:能够掌握数词和介词的用法;

教学难点:数词中基数词和序数词的用法区别,介词中时间,方位介词用法区别及掌握一些必背介词短语。

第一课时数词。

一)基数词。

1. 基数词的读法与写法:个位与十位之间加连字符“-”每隔三位加一个单位数词,从后向前数分别为thousand, million, billion,每个单位数词之间加一个逗号。

注意只有每个单位数词中百位和十位或者百位和个位(无十位时)之间加and。

25: twenty-five 137: one hundred and thirty-seven

3,782: three thousand, seven hundred and eighty-two

4,750,000,000: four billion, seven hundred and fifty million

2. hundred, thousand, million, billion的用法:

1)当hundred, thousand, million, billion前面有基数词表示具体的数量或与several, some, many等连用时,要用单数形式,如:

five hundred people several million trees

2)当表示笼统,不具体的数量时,用复数,其后加介词of,如:

hundreds of students thousands of factories millions of birds

练一练。girls took part in the happy girl competition but only few of them succeeded.

a. million of b. many million of c. one million of d. millions of

二)序数词。

1.基数词变序数词的方法:一,二,三要全变,其余后加th,时有例外,八去t,九去e,字母f代ve,ty变成tie(21-99等数,十位数用基数词,个位数用序数词,而且十位和个位之间加连字符“-”

第八:eighth 第九:ninth 第十二:twelfth

第二十:twentieth 第二十一:twenty-first

2.序数词前一般加the,但表示“再一,又一”时要加a,如:

would you like a second try?

3.若序数词前已有物主代词或名词所有格时,其前不加the。

练一练。i got a beautiful bike onbirthday.

三)分数。1.分数表示法:分子用基数词,分母用序数词,当分子大于一时,分母加s;带分数时,基数词+and+分子基数词+分母序数词。

2.分数的用法:当分数+of+名词/代词时,谓语动词要根据名词/代词的单、复数,或可、不可数名词来决定,如:

one third of the students in our class are girl students.

two fifths of money is spent on books.

四)时间。1.数字表示的年份通常分成两半来说,如:

1074: ten seventy-four 1880: eighteen eighty

注:1902: nineteen o two 或nineteen hundred and two

2008: two thousand and eight

1900: nineteen hundred
