一、the+more…，the+more…
　　the+比較級…，the +比較級…意為"越……，越……"，表示一方的程度隨著另一方的變化而變化，其中的兩個the都是副詞，而不是冠詞，前面部分是從句，后面部分是主句。
　　【例如】
　　the more people you know, the less time you have to see them.
　　你認識的人越多，見他們是時間就越少。
　　the busier she is, the happier she feels.
　　她越忙，就感到越快活。
　　the greater (is) the resistance, the less (is) the current.
　　電阻越大，電流就越小。
　　the sooner, the better.
       越早越好。
 
二、比較級的修飾詞
　　比較級可以用much, far, a lot, a great deal, a little, a bit, by far來修飾。
　　【例如】
she is much more beautiful than i have thought.
the situation is far more complicated than i have imagined.
i can do a little better than you. let me do it.
 
三、不用than的比較
　　并不是所有的形容詞表示比較時都用than，英語中有幾個以-or結(jié)尾源于拉丁語的形容詞，由于其原級已具有比較的含義，在表示比較時不用than，而用to。這類形容詞不多，計有：anterior / prior to(先于)，posterior to (在……之后)，superior to(優(yōu)于)，inferior to(劣于)，junior to(年幼于)，senior to(年長于)。
　　【例如】
　　this task is prior to all others.
　　he thinks he is superior to his classmates because his father is a very important people.
　　the red army was inferior in equipment but superior in morale to the enemy.
　　my arrival in beijing is posterior to that of our manager.
　　it happened prior to my arrival.
　　the official’s rank is senior to his father’s.
　　mary is two years senior to me, and her sister is junior to me by three years.
 
四、幾個含有than的結(jié)構(gòu)
　　1) no more than
　　只，僅僅，只不過是(=only)，后面接名詞或數(shù)詞，在句中起形容詞作用。例如：the street is no more than two miles long.這條大街只有兩英里長。what he is saying is no more than a joke.他所講的只不過是個玩笑而已。the estimate of 20012 tons was probably no more than another wild assumption of theirs.這個二萬零一十二噸的估計數(shù)字，也許只不過是他們的又一個胡編亂造。
　　2) no more... than (= not...any more than)
　　和……一樣不(not...any more than)。than前后都是否定的含義。
　　a whale is no more a fish than a horse is. (= a whale is not a fish any more than a horse is.)鯨和馬都不是魚。(鯨之非魚類，正如馬之非魚類。)
　　my elder brother is no more a singer than i am.我哥哥和我都不是歌唱家。
　　they will no more sell their freedom for roubles than for dollars.他們既不會以他們的自由換取美元，也將同樣不會以自由換取盧布。
　　the little man was ____one meter fifty high.
　　a) almost more than b) hardly more than　　c) nearly d) as much as
　　hardly more than用來表示"僅僅"。根據(jù)句意：這個小個子男人僅有1.5米高，應選擇b.

3)no other than 
　　只有，正是。它常用來加強語氣，多用于書面語。
　　the murderer turned out to be no other person than the inspector himself.結(jié)果是，那個殺人犯不是別人，正是巡官自己。
　　the beaten enemy had no other choice than to surrender.被打敗的敵人只有投降。
　　4)no better than
　　和……一樣，實際上等于(practically the same as)
　　a man who cannot read and write is no better than the blind.不識字的人跟瞎子沒有兩樣。
　　the patient is no better than he was yesterday.病人的情況和昨天一樣。
　　5)no less... than
　　和……一樣，不遜于。其中的than前后都是肯定的意思。
　　this person is no less diligent than he used to be.這個人和從前一樣勤奮。
　　the technique of writing is no less difficult than that of the other arts.寫作技巧和其他藝術(shù)技巧一樣困難。
　　sunlight is no less necessary than fresh air to a healthy body.日光和新鮮空氣對身體健康是同樣必不可少的。
　　6)no less than
　　多達，竟有……之多，不下于(as many as, as much as)。
　　in the battle, the red amy wounded were no less than twenty thousand.在這次戰(zhàn)斗中，紅軍傷員不下兩萬人。
　　he won no less than 1000 yuan in the lottery.他居然中了一千元的獎券。
　　the bank pays him a yearly salary of no less than ,000.銀行給他的年薪竟高達九萬。
　　7) other than
　　意思是：不同于，除……之外；rather than意思是：而不是。
     【例如】
　　this crop doesn’t do well in soils ____the one for which it has been specially developed.
　　a) beyond b) rather than c) outside d) other than
　　other than意思是：不同于，除……之外；rather than意思是：而不是。根據(jù)句意：除了這塊專門為它培育的土壤，這種作物在其它土壤上都生長不好。應選擇d.
　　in no country ___britain, it has been said, can one experience four seasons in the course of a single day.
　　a) other than b) more than c) better than d) rather than
　　句意為：除了在英國，一個人不可能在其它國家在一天內(nèi)經(jīng)歷四季。other than表示"除……之外"，故選擇a.
