Talk about personalities. ? 三. 具体内容： （一）enough ? 1. enough修饰形容词或副词时必须位于被修饰的词语之后。修饰名词时一般位于其前，也可位于其后。enough后面通常接不定式短语或介词for短语。 ??? e.g. The question is easy enough. ?????? Tom didn’t do his homework carefully enough. ?????? The water is cool enough to drink. ?????? We have enough tickets for all of you. ? 2. 修饰形容词时，如果用于否定句，则否定句在否定enough的同时，也否定了其后的不定式。 ??? e.g. He is not careful enough to do the work. ????? She is not old enough to go to school. ????? enough如果修饰名词，用于否定句时，不定式没有被否定之意。 ??? e.g. There were not enough people to pick the apples. ? 3. enough也可以做代词，意思是“足够，充足”。 ??? e.g. We have enough to do to complete the project. ? （二）too…to… ??? too+形容词或副词+(for sb.)+to do 表示“太……以至于不能……”，不定式虽然是肯定形式，但与前面的搭配构成了否定的含义 ??? e.g. The book is too difficult for you to read. ?????? She is too short to catch the apples on the tree. ??? 在too…to结构中，too前面用了never这个词，则动词不定式可以把否定变为肯定。 ??? e.g. It’s never too old to learn. ? （三）修饰性副词。 ??? 根据汉语意思，选择恰当的修饰性副词。 1. rather, a bit, a little 可减轻形容词的绝对性。 2. really, extremely, quite 可起到强化形容词的作用。 3. at all用于否定句加强语气。 e.g. He is rather stubborn. ? I am a little careless. ? She is a bit absent-minded. ? He is extremely patient. ? I am not serious at all. ? They’re quite friendly. ? （四）to give reasons and purposes e.g. 1)—Why did you get a pet? —To have company. 2)—Why do they use animals for treatment? ? —Because they help people relax. 3)—Why do you talk to your parents about everything? ? —So they trust me. 4)I want a pet to take it for walk. 5)Animals are good listeners because they don’t stop you.
