( )四、总结（引深探究 15分钟）几个值得注意的比较级句式一、the+比较级, the+比较级此句型表示后者随着前者的变化而变化，意为“越就越”，前者相当于一个条件句，因此，要用一般现在时代替一般将来时。如：The better I knew him, the more I liked him.
8、我越了解他就越喜欢他。The more difficult the questions are, the less likely Ill be able to answer them. 题目越难我越答不出。二、the+比较级+of the two表示“两者中较的那个人或物”时，在比较级前加定冠词the。如：He is the taller of the two. 他是两人中较高的那个。She was the more promising worker of the two. 她是两人之中更有培养前途的工人。三、比较级+and+比较级此句型表示“越来越”，单音节形容词或副词用“-er+and +
9、-er”，如：Things are getting better and better every day. 情况一天天好起来。Its becoming more and more difficult to find a job. 找工作越来越困难了。Holiday nights are getting less and less expensive. 假日机票越来越便宜了。四、not +比较级+ than / no +比较级+ than比较级前加not，表示前者不如后者，与not asas相当；比较级前加no是对两者的否定，意为“和一样不”，与neithernor或“as+相反意义的形容词或
10、副词+as”相当。如：He is not taller than me. 他不如我高。He is no taller than me. 他同我一样不高。(即一样矮)His English is not better than mine. 他的英语不如我的英语好。His English is no better than mine. 他的英语同我的英语一样不好。(即一样差)You are not more careful than he is. 你不如他仔细。You are no more careful than he is. 你和他一样不仔细。(即一样粗心)五、less / least +原
11、级“less原级”表示降级的比较级；“least原级”表示降级的最高级。如：Would you mind speaking less quickly? 你可否讲得慢一点?The movie was less funny than the book. 电影没有书那么滑稽有趣。This is the least useful of the four books. 这是四本书中最没用的一本。It is said that those who eat the most are the least healthy. 据说吃得最多的人身体最差。六、lessthan的用法1. 本身用作比较级：把more看成
12、many或much的比较级，后接名词，表示“比更多”。如：Statistics show that there are more boys than girls at school. 统计数字表明学校的男生比女生多。 2. 后接多音节形容词和副词：more后接多音节形容词或副词，前后是两个或两类人或物进行比较时，表示“比更”。如：Airports were more closely watched than anyplace else. 飞机场比任何其他地方看守得更严密。All human beings are much more intelligent than animals. 所有人类的
13、智力都比动物高得多。3. 对同一对象的两个方面进行比较：若是对同一个人或物在不同方面进行取舍时，意为“与其说倒不如”，此时，不论形容词或副词是单音节、双音节还是多音节，一律用morethan。如He is more hungry than tired. 与其说他累了，倒不如说他饿了。I was more annoyed than worried. 我与其说是着急，不如说是生气。五、练评（包含“考点链接” 应用探究 6分钟）1.
