等。

无论肯定还是否定应答中，要记得避免使用could，要用can或may。因为应答须用确定的语气。而could在表请求的问句中是为了表示礼貌或委婉语气，用在应答中则成了不确定语气，与情理不符。所以应答中不说Yes, you could.或No, you couldn't. 而要说Yes, you can. 或Sorry. /No, you can't.

（2）．区别动词do和make。

"do"与动作及非实质性的事连用，与词尾是-ing的动作名词连用，如：do the dishes（洗餐具），do my homework（做我的家庭作业），do chores（做家务，处理琐事），do the laundry（洗衣），do the shopping（购物），do some reading（读书）

"make"表示"做、制造"、"整理"、"冲、泡（饮料）"等，如：

make your bed（铺床），make breakfast（做早餐），make dinner（做晚饭），make tea（泡茶，沏茶），make myself a cup of coffee（给自己冲一杯咖啡）
