1. 在及物动词、介词、冠词、形容词性物主代词,以及some, any, other等词后,若后面没有名词时,应填名词或动名词,如果所给单词是其它词类,就要将其改为名词, 并注意名词数的变化。如:
(1)Do you know the ________ (deep) of the river?
(2)The teacher was angry at my ________ (come) late.
2. 在动词前后、形容词或副词前作状语,用副词,同时还要考虑级的变化。如:
(1)The boy ran ________ (quick) to school.
(2)The little girl is ________ (extreme) eager to know the result of the exam。3. 作定语、表语(表性质特征)或补语的典型词类是形容词,同时还要考虑级的变化。如:
(1) What’s the ________ (width) river in the world?
(2) The ________ (strength) we become, the more modest we should be.
。4. 在句中作谓语用动词,同时考虑动词的时态。如:
It is generally thought that traveling abroad can ________ (rich) one’s knowledge.[例1]This proverb is saying we have to let things go in their 39 (nature) course(2008广东)
[例2]We drank together and talked 38 (merry) till far into the night (2007广东)
