each
[误] Every of them has his habit.
[正] Each of them has his habit.
[析] each可以作形容词，但也可作代词，而 every只能作形容词。
[误] The manager comes to America almost each month.
[正] The manager comes to America almost every month.
[析] each与 every都作形容词讲时，都有"每个"之意，但有不同。 each多指个体，而 every则多指整体。如： We want every student to succeed. each不同来表达总体概念，所以不能与 almost, nearly， likely等词连用。
[误] We each has a book.
[正] We each have a book.
[析] each作同位语时，其数应与其同位的名词相同，而 each作主语时则应取其单数形式。
each other one another
each other与 one another这两个词组的区别在很多语法书中强调 each other是两者之间，而 one another是多者之间，其实不然，如： All students must care for each other, must love and help each other. 事实上这两个词组是同义的，如果要讲有什么区别的话，当我们非常笼统地谈，而不特指什么人时，多用 one another.
early
[误] Could you come here more early?
[正] Could you come here earlier?
[析] 单音节和少数双音节副词的比较级和最高级要用 er和? est来作其结尾，如 fast, soon, early, hard, long, near等。
earth
[误] What on the earth do you mean?
[正] What on earth do you mean?
[析] on earth这一词组在句中为的是加强语气，其意为"究竟"、"到底"。而作为"地球"讲时则要加定冠词，如： How far is the earth from the moon. 而作为"泥土"讲时则为不可数名词，如： He filled the pot with earth and wanted to plant some flowers.
easy
[误] You can easy imagine my surprise.
[正] You can easily imagine my surprise.
[析] easy只在有限的词组中被用作副词，如 take it easy(不要紧张)， go easy, stand easy等。例如： Easy come, easy go. (钱来的容易花的也快 ) Easier said than done. (说的容易做着难。)
east
[误] Japan is on the east of China.
[正] Japan is to the east of China.
[析]在讲述地理位置时，有 3个介词常用，它们是 in, on和 to,其中 in表示处于所表达的范围之内，如： Shanghai is in the east of China. on则 ina. 而表示互不相接的两部分时则用 to,如： Taiwan is to the east of Fujian.
either
[误] - I don't like opera.
- I don't like too.
[正] - I don't like opera.
- I don't like either.
[析]在否定句中用 either表示"也"，而在肯定句中用 too表示"也"。
[误] Either you or I are right.
[正] Either you or I am right.
[析]这在语法书中被称作就近原则，即哪个主语离谓语动词近，则应采用与哪个主语相一致的谓语动词，相同用法的还有 neither… nor…， not only… but also…，以及 or在连接两个主语时。如： You or he is to go home. The others will have to stay in the classroom.
elder
[误] My older brother has gone to Shanghai.
[正] My elder brother has gone to Shanghai.
[析]在表示兄姐的长幼时应用 elder表示"哥哥姐姐"，如： my elder sister姐姐，但表示岁数时则多用 older，如： She is two years older than I.
empty
[误] Are these seats empty?
[正] Are these seats taken?
[析] empty是指空洞的没有任何物体，如： The house was empty,其意思是没有任何家具或屋内无人。但座位是否有人坐应用 take.
English
[误] My sister studied English language very well.
[正] My sister studied the English language very well.
[正] My sister studied English very well.
[析]在泛指某一种学科时，不应加冠词，如： I like history.但如特指某一门学科时则应加冠词，如： He likes the history of America.
enjoy
[误] I enjoy to play football.
[正] I enjoy playing football.
[析] enjoy后要接动名词，而不接不定式。
[误] Did you enjoy at the English evening?
[正] Did you enjoy yourself at the English evening?
enough
[误] I'm sorry. You are not studying enough carefully.
[正] I'm sorry. You are not studying carefully enough.
[析] enough要用在形容词或副词之后。
[误] Do you have enough of money?
[正] Do you have enough money?
[正] Do you have enough of the money?
[误] The coffee isn't enough.
enough可以作 be动词的表语，但其主语应是代词，如： That's enough. It was enough.
如果是名词时应换用上面的句型。
