far

1.far和by far略有不同，下面几点该注意：

（1）far用在属于比较级或最高级的词前面都可以，如This is far better than that和This is far the best of the five。

（2）by far可以用在属于最高级的词前面，不可用在属于比较级的词前面，如可以说This is by far the best of the five，不可说This is by far better than that。但用了the便可以把by far用在前面。例如：This is by far the better of the two.

（3）by far可以用在属于比较级的词后面。例如：This is better by far than that. 但这种用法不很普通。

2.far from作“极不”解，如This is far from perfect和I am far from considering it perfect。注意第一句里在far from后面直接接形容词perfect，在那形容词前面加上being也可以，但不很普通。

3.下面三句意思相同：

She is so far from liking the man that she intends never to see him again.

Far from liking the man, she intends never to see him again.

So far from liking him, she intends never to see him again.

第三句原来是从第一句和第二句混合而来。

4.so far as, as far as和in so far as的意思相同，可以换用。例如：So far as（或As far as，或In so far as）I can see, they are all satisfied with the arrangement. 但in so far as比较不普通。

5.注意在He went as far as Tibet等句子里在第二个as后面没有to。在far后面加上afield或west也可以，但在as后面也不该有to。同样地，as far back as the fifteenth century等表达方式里在第二个as后面没有in。

6.How far did he go？是疑问句，He did not go far是否定句。He went far很不自然，最好改作He went a long way。
