8、 him, the more i liked him. 我越了解他就越喜歡他。the more difficult the questions are, the less likely ill be able to answer them. 題目越難我越答不出。二、the+比較級+of the two表示“兩者中較的那個(gè)人或物”時(shí)，在比較級前加定冠詞the。如：he is the taller of the two. 他是兩人中較高的那個(gè)。she was the more promising worker of the two. 她是兩人之中更有培養(yǎng)前途的工人。三、比較級+and+比較級此句型

9、表示“越來越”，單音節(jié)形容詞或副詞用“-er+and +-er”，如：things are getting better and better every day. 情況一天天好起來。its becoming more and more difficult to find a job. 找工作越來越困難了。holiday nights are getting less and less expensive. 假日機(jī)票越來越便宜了。四、not +比較級+ than / no +比較級+ than比較級前加not，表示前者不如后者，與not asas相當(dāng)；比較級前加no是對兩者的否定，意為“和一樣

10、不”，與neithernor或“as+相反意義的形容詞或副詞+as”相當(dāng)。如：he is not taller than me. 他不如我高。he is no taller than me. 他同我一樣不高。(即一樣矮)his english is not better than mine. 他的英語不如我的英語好。his english is no better than mine. 他的英語同我的英語一樣不好。(即一樣差)you are not more careful than he is. 你不如他仔細(xì)。you are no more careful than he is. 你和他一樣

11、不仔細(xì)。(即一樣粗心)五、less / least +原級“l(fā)ess原級”表示降級的比較級；“l(fā)east原級”表示降級的最高級。如：would you mind speaking less quickly? 你可否講得慢一點(diǎn)?the movie was less funny than the book. 電影沒有書那么滑稽有趣。this is the least useful of the four books. 這是四本書中最沒用的一本。it is said that those who eat the most are the least healthy. 據(jù)說吃得最多的人身體最差。六、l

12、essthan的用法1. 本身用作比較級：把more看成many或much的比較級，后接名詞，表示“比更多”。如：statistics show that there are more boys than girls at school. 統(tǒng)計(jì)數(shù)字表明學(xué)校的男生比女生多。 2. 后接多音節(jié)形容詞和副詞：more后接多音節(jié)形容詞或副詞，前后是兩個(gè)或兩類人或物進(jìn)行比較時(shí)，表示“比更”。如：airports were more closely watched than anyplace else. 飛機(jī)場比任何其他地方看守得更嚴(yán)密。all human beings are much more int

13、elligent than animals. 所有人類的智力都比動物高得多。3. 對同一對象的兩個(gè)方面進(jìn)行比較：若是對同一個(gè)人或物在不同方面進(jìn)行取舍時(shí)，意為“與其說倒不如”，此時(shí)，不論形容詞或副詞是單音節(jié)、雙音節(jié)還是多音節(jié)，一律用morethan。如he is more hungry than tired. 與其說他累了，倒不如說他餓了。i was more annoyed than worried. 我與其說是著急，不如說是生氣。五、練評（包含“考點(diǎn)鏈接” 應(yīng)用探究 6分鐘）1.
