Lesson41写作专练题目：谈谈中国的节日解析：说起中国的节日，必然用到日期和月份，用到数词和it 因此，我们要首先弄清楚日期和月份，数词和it的用法指路：一.数词 数词分为基数词和序数词两种1. 基数词：表示“多少”的词叫基数词如：one, two, three, four….thirteen, fourteen…twenty, thirty…one hundred 说明： （1）13-19皆以后缀-teen结尾，他们都有两个重音 （2）20-90等十位数的整数均以后缀-ty结尾3）十位数和个位数之间均须用连字号“-”，如：ninety-nine, twenty-one2. 序数词：表示“第几”的词叫序数词如：first, second, third, fourth…thirteenth, fourteenth…twentieth, thirtieth…sixty-third, ninety-fourth说明：（1）英语序数词1-19除第一（first）,第二（second）,第三(third) 有特殊形式外，其余均为基数词后加-th构成。
2）由几个序数词加-th时拼法不规则，它们是：fifth, eithth, ninth, twelfth3）十位整数的序数词的构成方法是：先将十位数整数基数词的词尾-ty中的y变成I,然后加-eth4）基数词“几十几”变为序数词时，仅将个位数变成序数词，十位数不变如：twenty-one 变成twenty-first5）序数词的缩写形式是由阿拉伯数字后加上序数词的最后两个字母构成如：1st, 2nd, 3rd有人把基数词变序数词编了一个口诀：变序，有规律；词尾加上th一、二、三特殊记，结尾字母t, d, d八减t, 九减e，f要把ve替是ty结尾的，先变y为I，记住th前加个e注释：一、二、三特殊记，结尾字母t, d, d是指first, second, third八减t 是指eight→eighth, 九减e是指nine→ninth, f要把ve题，是指five→fifth, twelve→twelfth, 最后两句是指十的整数，如：twenty→twentieth二. it 的用法：it可以用来表示时间、距离和天气例如：---What time is it? 现在几点了?---It’s six o’clock. 六点了。
How is the weather today? 今天天气怎麽样？---It’s cloudy. 阴天 范文：In China, we have many important days: New Year’s Day, Spring Festival, International Workers’ Day, Children’s Day, Teachers’ Day and National Day. New Year’s Day is January first, Spring Festival is in January or February, International Workers’ Day is May first, Children’s Day is June first, Teachers’ Day is September tenth and National Day is October first. When New Year’s Day and Spring Festival come, we say “Happy New Year” to each other. We wear new clothes. We eat delicious food. We go to see our grand fathers and grandmother, fathers and mothers, and friends. When Teachers’ Day comes, we say hello to our teachers. When Children’s Day comes, we often have gifts from our fathers and mothers. 资料来源：。
