Task 6
Role-play
1. Are you free next week?
free adj. “空闲的;有空的”,反义词 “busy” 。
be free = have time. be busy = have no time.
free 还可“免费的;自由的”。
The cola is free. You don’t have to pay for it.
You’re free to go or to stay. 你想走就走,想留就留。
be free to do sth. / feel free to do sth. “自由做某事”
be free with sth. 对…随便 be free with sb. 对某人放肆
be free of “无...的,免除…”
be free from... “免除或摆脱(一些不好的东西) ”
for free “免费,不花钱”
Language points
2. Hmm…next week is quite full for me, Jack.
full 的用法:
① adj. “忙的,有很多活动的”, 同义词为busy, 反义词为free。
e.g. He had a full weekend.
② adj.“满的;充满的”,其反义词为empty (空的)。
e.g. The restaurant is full every day.
【短语】be full of ... “充满...,装满...
同义短语:be filled with...
eg:The classroom is full of students.
= The classroom is filled with students.
③ adj.“吃饱的”,其反义词为hungry。
? e.g. I’m full, so I don’t want to eat anything.
Language points
3. How come? 意为 “为什么呢?; 怎么会呢?”
英语口语中的习语,相当于why,既可以独立使用,也可在其后接句子,用来询问事情的缘由或状况。
e.g. How come the sky is so blue today?
= Why is the sky so blue today?
今天天怎么会这么蓝?
How come you get up so early?
= Why do you get up so early?
你为什么起这么早?
Language points
【注意】
How come ? = why? 但how come开头的特殊疑问句使用的仍是陈述语序。
How come you didn’t tell me about it?
= Why didn’t you tell me about it?
你为什么不早点告诉我这件事?
How come Tom didn’t come to the party?
