四、语法与用法要点
1. 询问颜色:What colour is it? / What colour is this now? 回答:It's + 颜色。
2. 猜测问句:Is it + 颜色/字母? 回答:Yes, it is. / No, it isn't.
3. 颜色混合:red + yellow → orange(橙);red + blue → purple(紫);yellow + blue → green(绿)。
4. 询问看到的字母:What letters can you see? 回答:I see A, T and M.
5. 字母 Oo–Zz 的认读与代表词:Oo orange、Pp pencil、Qq queen、Rr ruler、Ss school、Tt tea、Uu umbrella、Vv vegetable、Ww winter、Xx X-ray、Yy yellow、Zz zebra。
6. "字母 Xx is for + 单词"表示"Xx 代表某单词":Oo is for orange.
7. 常用口语:I'm not done yet!(我还没完成呢!)Hold on!(等一下!)To me, it's...(在我看来它是……)
8. 句首字母大写;句子开头 What 首字母大写。
五、易错提醒
1. colour 是英式拼写,美式写 color,选定一种保持一致,不要混用。
2. orange 既可指"橙色"也可指"橙子",看语境。
3. Is it...? 的回答:Yes, it is. / No, it isn't.(it is 缩写 it's,is not 缩写 isn't)。
4. 字母 Oo 和数字 0、字母 Qq 形状相近,书写时注意区分。
5. 句首 What、疑问句首字母大写:What colour is it?
6. "字母"是 letter,不要写成 Latter 或 latter。
六、文化小知识
本单元学完 26 个英文字母中的 Oo–Zz,加上前两单元的 Aa–Nn,26 个字母全部学完啦!
PRC 是 the People's Republic of China(中华人民共和国)的英文缩写,出现在国旗旁。
色彩小常识:红 + 黄 = 橙;红 + 蓝 = 紫;黄 + 蓝 = 绿;这叫三间色调色法。
