5． Inf的其它形式： 
1）将来式： 
主动：be to do　 
被动：be to be done　 
eg: China is to be one of the most important countries in the new 
century. 
* to be done & done的区别： 
the surface to be glaued 表将来 
the surface glwed 表完成 
2）完成式： 
主动：to have done　 
被动：to have been done 
表示不定式的动作发生在谓语前 
eg: I am glad to see you again.　动作同时发生 
I am glad to have seen his sons yesterday.　am glad表示现在的动作 to 
have seen表示昨天的动作 
3）The problem is easy to solve. 
The problem is difficult to carry out. 
在easy　difficult　hard　simple等形容词后的不定式主动表示被动 

六、形容词的比较级与最高级：（讲义 P4 74-81） 
考点：形容词的词性混用，两个近义形容词的混用（small pressure→low 
pressure）(讲义P22 92.5.36)，原级、比价级和最高级的混用，词序问题。 
1．形容词的比较级与最高级形式上的重复： 
eg: more sreater X 
most easiest X 
lesser…than X 
2．形容词比较级与最高级的混用： 
⑴more… of all +n(pl)/in the world/among… 
这里的more错，more→most 

⑵most…than X → more…than 
eg: Pennsylvania has the more institutions of higher learning than 
any other state. 

⑶常考的修饰比价级的词： 
a little　a bit　slightly　far (more)　much (more)　still (more than)
　a lot (more than) 
eg: be much abundant in…X → very 
so much close to …X → very 
much&very：much修饰比较级，very修饰原级，不可以互换 
very/much…be　　 much attracted by…√ 

⑷形容词原级与比较级的混用： 
adj原级…than X → adj.比较级 
less+原级…+than 
as+原级+as　同级比较 

⑸the most often X → most / very often 
　more conect X 
　more perfect X 
绝对/极限形容词或者副词，没有比较级、最高级，如：round　vertail　othen
　perfect　unique　empty　wrong　absolutely等 
例外：the most perfect √ 表示极其完美之意，由口语引入到书面语 

⑹倍数表达法： 
a 倍数+as+a.原级+as 
Tom is three times as old as Jerry.　（Tom的年龄是Jerry的三倍） 
The care is threee times as deep as the building is high. 
b 倍数+more than 
Tom is twice older than Jerry.. 
c 倍数+n.+of （名词为比较的方面） 
Tom is three times the age of Jerry. 
d 倍数+that / those of 
His weight is three times that of mine.　 That of=as much as 

⑺定冠词the与比较级的关系： 
Alarska has the lower temperture than Texas. X →Alarska has lower 
temperture than Texas. 
*比较级前可以加the,.但得有对照，比如：the newer…the older… 
eg: The taller boy is much more attractive than the shorten one. 
*the +adj-er+of+the two +pl. 
eg: Tom is the taller of the two boys. 
　　Joans is the fatter of the two girlsfriends of Bill’s. 

⑻the与最高级的关系： 
a Flies live longest in cold weather 
副词最高级前通常没有the 
b 当形容词最高级做前置定语修饰名词时，加the 
the largest school　 
c 当形容词最高级做后置定语时，不加the　 
a design most similar to that one 
d 形容词最高级做表语时，the可加可不加 
This is where the river is deepest. 
The consumers considers the best fmit (to be) that which is the most 
acteacture.　that=that fruit，代词 

e 所有格可以代替the修饰最高级（讲义 P4 81） 

f earliest的三种用法： 
1）“早期”，n. 
… from the earliest of Tang Dynasty. 
2）形容词原级，“很早，非常早” 
from earliest times/ages 从远古年代 
（可以不加the） 
3）形容词最高级 
the earliest language(s) is/are… 

⑼…or more结构 
thirty-five years of age be older X → thirty-five years of age or 
older 
一英尺以上：an inch or more　　　√ 
an inch or more than　X 
an inch or be in more　X 

七、平行结构（讲义P4 87-89） 
由平衡连接词连接的两个以上的对等对象构成 
㈠平衡连接词： 
1． 单一式：and but or 
2． 短语式：as well as　other than　rather than　instead of　would 
rather…than　instead of 
3． 相关式：from…to　between…and　not…but　from…until　either…or
（引导从句）　weather…or(引导从句)　such as　as…as　the same as　
not only…but also　neither…nor 

㈡平行式： 
1．A and B　not A but B　A as well as B…　 
2．A, B ,and /or C（常考）　A,B,as well as C 
3．A, B and C（不常考） 

㈢平行的性质：一致性问题 
1．词性平行（讲义P4 84） 
city and regional planning 
*在平行结构中，词性必须一致，但是无同义形容词的名词例外，如city没有同
义词（urban不表示“城市的”意思“） 
eg:local, state, and national government 

2．时态平行：时间决定时态，在平行结构中，时态可以不一致也可以不一致，
如果时间相同，则时态同
