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.&
