新課學習
1. 學習指示代詞, 應注意以下幾點:
① this與is, these與are沒有縮寫形式。
This is a Chinese car. 這是一輛國產轎車。
② 指示代詞作主語指物并用于問句中時, 回答一般用:
it代替this和that; they代替these和those。
-- Is that a ruler？那是尺子嗎？
-- No, it isn’t. It’s a pen. 不, 不是。是鋼筆。
-- Are these your books? 這些是你的書嗎?
-- Yes, they are. 是的。
2. no和not
二者都是“不”的意思, 用法不同。
no: 可單獨使用，用于回答一般疑問句，
反義詞為yes；
not: 不能單獨使用，要和be動詞、助動詞等一起構成否定句。
--- Is this your pencil? 這是你的鉛筆嗎?
--- No, it isn’t. 不, 不是。
It is not my book. 這不是我的書。
