I dont know what to say.（三）、tooto /enough to和sothatsothat引导的结果状语从句可以用tooto和enough to改成简单句，若从句是否定含义既可用“too形容词/副词to”改写，也可用“not形容词/副词（原句中形容词/副词的反义词）enoughto”改写；若从句是肯定含义常用enough to改写。如：1. The girl is so young that she cant join the army.The girl is too young to join the army.或The girl is not old enough to join the army. 这个女孩太小不能参军。2. He runs so fast that he can get there first.He runs fast enough to get there first. 他跑得够快，可以第一个到那儿。五、同步练习：完成书中练习。见P50 和P51.六、当堂检测用动词的适当形式填空 1、 Dont make him_(climb) the tree. 2、 Father asked his son_(not play) with fire . 3、 After having a rest , he went on _(do) his homework . 4、 Its important _(do) morning exercises every day . 5、 To a doctor the most important thing is_(save) lives . 6、The workers were made _(work) more than ten hours a day . 7、 How _(get) to the science museum is a question . 8、 It takes me half an hour_(go) to school on foot . 9、 They stopped_(listen) to her songs because they were fond of singing. 10、Its rather cold ,youd better_(not take) off your coat 11、Its kind of you _(give) seat to the old man . 12、He had a lot of work_(do). 13、Would you please_(give) the boy something _(eat) 14、Would you like him _(get) some water for you ? 15、I saw Mary _(play) with her sister under the tree. 课后练习单项选择1.
