第一部分:知识点分析。

一、基数词。

1)基数词读法: 年,月,日,时刻的读法,如2024年六月十三日读作:june (the) thirteenth, two thousand and seven

主要体现在口语考试和听力题目中)

2)表示一个具体数字时,hundred, thousand, million, billion一律不用复数;在表示一个不确定数字时则用复数。例如:

there are three thousand students in our school.

after the war, thousands of people became homeless.

3)在一些表示"一排"或"一组"的词组里;

如:they arrived in twos and threes. 他们三三两两的到达了。

4)表示"几十岁", 例如:he died still in his forties.

5)表示"年代",用 in +the +数词复数;

二、序数词。

1)序数词主要用作定语,前面要加定冠词,例如:

the first truck is carrying a foot baskets.

2)序数词有时前面可加不定冠词来表示“再一”,“又一”这样的意思,例如:

we'll h**e to do it a second time.

3) 注意较为容易拼写错误的序数词及其缩写形式:one---first, two---second, three---third, five---fifth, eight---eighth, nine---ninth, twelve---twelfth。

缩写形式:first→1st second→2nd third→3rdfourth→4th twenty-second→22nd

4) 表示分数时,分子用基数词表示,分母用序数词表示。分子大于1时,分母加-s。例如:

three fourths, one second, two fifths

2、难点 倍数表示法。

主语+谓语+倍数(或分数)+ as + adj. +as

i h**e three times as many as you. 我有你三倍那么多。

3、易错点。

1. we will h**e aholiday after the exam.

a. two month b. two-month c. two month’s d. two-months

答案: b (选择c的同学要注意应用two months’; 选择d的同学要注意名词之间有 “—后的组合词当作形容词来用, 因此就不用所有格形式了。)

2trees are cut down in the forests every year.

a. thousand b. thousands c. thousand of d. thousands of

答案: d. (选择c的同学注意词组记忆的准确性)

3. our sports meeting will be held

a. on 24, tuesday, april b. in april 24, tuesday

c. on tuesday, april 24 d. in april tuesday 24

答案: c. (选b的同学是受到中文的影响,要特别注意中英文的差异)

may 20th,2002,the twentieth of may,2002

注。4. i'm very hungry, i h**e eaten two cakes, would you please give me one?

a. move b. three c. a third d. the third

答案: c. 序数词前加不定冠词,表示“又一,再一”,表示another。

5. of the land in the world is covered by water.

a. four three b. three four c. three fourth d. three fourths

答案: d. 此题考查分数的写法,如果分子大于1,分母用复数。
