专项讲解及练习

一）数词

1、重难点突破

1）基数词

①基数词读法：年，月，日，时刻的读法，如2007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；

2）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 have 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→3rd fourth→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
