考查形容词比较级和其修饰词。far修饰形容词比较级，一般放在所修饰词前表程度，在此要讲解far与by far的区别。by far可以修饰比较级和最高级，但要注意其在句中的位置。It is by far the best film that I have ever seen./ It is the best film by far that I have ever seen./His work is better by far than that of any other printer in the city./Of the two girls, she is by far the better actress.当by far与形容词或副词的比较级或最高级连用时，置于这类词之后；若这类词带有冠词the或a时，则置于这类词前的均可。fairly一般不修饰比较级。
