15、re is a “n” in the word.是错句，应为：There is an “n”in the word.因字母n的发音的第一个音素是元音。要注意的还有hour因其第一个字母h不发音，所以应该用an hour。例如：I need an hour to finish the work.It is a useful dictionary.It is a European country.I bought a used car.正I need an umbrella because it looks like raining.误I need a umbrella because it lo
16、oks like raining.析因umbrella的第一个音素是元音，所以应用an.常用的情况有：an old man, an English teacher, an elephant, an idea, an hour ago, an honest boy。正“Can you help me” “Sorry.

20、nguage this term.误I want to learn the second language this term.析在序数词的含意不是顺序中的第一第二，而其意在于再学一个，再来一个时，应用a，本句的意思应为：这学期我要学一门第二外语。误Mississippi is one of the longest rivers in the world.正The Mississippi is one of the longest rivers in the world.析在河流名称前应加定冠词，如：the Yellow River（黄河）。误Look, there are Alp.正Look

The bread sells in this shop is very good.误I like to eat bread for breakfast. Bread sells in this shop is very good.析物质名词特指时也应加定冠词。误The sun rises in

26、正I bought the same dictionary as she bought.析在惯用法the same, the only, the very前的定冠词不可换为不定冠词。误The police caught the thief by his arm.正The police caught the thief by the arm.析这是英文表达法与中文的明显不同之处，也是初学者极易忽视之处。在英语中的某些动词，如：catch（抓），take（拿），strike （打）,pat（拍），hit（击），hold（握），pull（拉）动词后应加人，再加介词on, by, in, with之后
27、要加定冠词，再加人体的某一部位。这时的定冠词千万不要换作his, her, their, 等词。正He was paid by the hour.误He was paid by hour.析by和计量单位之间要有定冠词。这句话应译为：他的工资是按小时计算的。误I went to New York by his car.正I went to New York by car.正I went to New York in his car.析by仅仅与交通工具相连表示应用某种工具，而加了别的修饰词后其前面的介词也应作相应的转换。by car （坐小汽车）by taxi （坐出租车）by bike （骑自行车）by water （乘船）by air （乘飞机）by sea （乘船）正Mary began to learn how to play the piano when she was three.误Mary began to learn how to play piano when she was three.析在乐器前要加定冠词，而在球类游戏之前则不要加冠词，如：They l
