8、解，下面就让我们根据之前练习的考察情况进一步选择讲解该语法项的重难点。enough to的用法可以用“to be + adjective + enough + to do”的结构来描述一个人的品质和能力。如：He is tall enough to reach the basket.他个头高，可以够到篮筐。The girl is not brave enough to go near the dog.这个女孩胆子不够大，不敢靠近那只狗。 . enough作定语，意为“足够的，充分的”，位于名词之前。 I have enough money for the book. 我有足够的钱买这本书。 Y

9、ou have enough time to do it. 你有足够的时间来做这件事。. enough作状语，意为“充足地，充分地”，修饰形容词或副词，放在形容词或副词之后。 That coat is dear enough. 那件大衣很贵。 Is this good enough? 这个够好吗？. enough作表语，意为“足够的”。 Six bottles should be enough. 六瓶应该够了。Suzy wants to tell her parents what she thinks about her friends. Help her make sentences usi

10、ng “to be + adjective + enough + to-infinitive”.Suzys friendshis friends/ kind/ any time/ help_Daniel Daniel is kind enough to help his friends any time.Millie listen/ patient/ when others speak/ carefully_Millie is patient enough to listen carefully.Sandy around her/ careful/ small changes/ notice_

11、Sandy is careful enough to notice small changes around her.Kitty generous/ with others/ her things/ share_Kitty is generous enough to share her things with others.Simon queue/ polite/ in public_Simon is polite enough to queue in public.Amy make everyone laugh/ funny/ after class_Amy is fuuny enough

12、to make everyone laugh after class.too.to的用法可以用“to be + too + adjective + to do”的结构来表达一个否定的结果。如：He is too tired to go on working.他太累了，不能继续工作。British people are too polite to laugh loudly in public.英国人太有礼貌了，不会在公共场合大声笑。 可以在不定式前加介词for引出逻辑主语。如： The box is very heavy. The little boy cannot to carry.= The

13、 box is too heavy for the little boy to carry. The apple is very high. The child cannot reach it.= The apple is too high for the child to reach.注意：. tooto结构和never一起使用是并不表示否定。如： One is never too old to learn. 活到老，学到老。. “to be + too + adjective + to do”结构相当于“to be +not +adjective+ enough+ to do”,这两个句型

14、中的形容词是反义词。1. He is too young to work.= He is not old enough to work.2. The girl is too short to see it.= The girl is not tall enough to see it.3. The question is too hard for me to answer.= The question is not easy enough for me to answer. The radio show is over. Millie wants to write about that day
