专题训练(二)巧用派生词,做好完形填空
技巧点拨: 动词前后、形容词前后可有副词,这时,如果所给词为形容词,则需将其变为副词。如果所给词为名词或动词,可先将其变为形容词,再加后缀-ly。另外,在答题时还要考虑副词级的变化。名词前面一般可有形容词修饰语,连系动词后接形容词作表语。如果所需词为形容词时,还要考虑形容词级的变化。如:
(1)The little girl is extremely (extreme)eager to know the result of the exam.
(2)Your composition is badly (bad)organized. Please do your writing exercise more attentively (attend)next time.
(3)What,s the longest (length)river in the world?
(4)The stronger (strength)we become, the more modest we should be.
(5)He was very tired after doing this for a whole day, but he felt very happy since the crop did “grow” higher (height).
