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 points2. 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 points3.

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? = Why didn’t Tom come to the party? 汤姆怎么没来参加聚会呢?Language points一、根据句意及首字母提示完成单词1. Most teenagers like surfing the I_______ on weekends.2.
