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…√
