陷阱2 用错“一两天”之类的表达
汉语说“一两天”，说成英语可用a day or two或one or two days，但是不能用 one day or two或a or two days。如：
One or two days are enough to see the city. 要参观这个城市一两天就够了。
Within a day or two he got a letter from them. 过了不到一两天他就接到他们的一封信。
请注意以下类似表达：
Only a word or two is needed. 只需说一两句话。
I shall be ready in a second or two. 一会儿我就会准备好。
陷阱3 用错“一个半”之类的表达
用英语表示“一个半”的方法是：a…and a half或one and a half…，但不能说one and a half hour。如：
我在一个半小时之内考试完毕。
误：I finished the examination in one and a half hour.
正：I finished the examination in an hour and a half.
正：I finished the examination in one and a half hours.
注意“两个半”“三个半”“四个半”之类的表达。如：
It’s about two and a half miles away. 大约有两英里半远。
This happened four and a half centuries ago. 这是四个半世纪前发生的事。
陷阱4 用错“每隔几……”的表达法
用英语表示“每隔几……”的最常用是：“every+基数词+名词（复数）”
We meet every few days. 我们每隔几天就会一次面。
Take some fruit every three or four hours. 每隔三四个小时，吃点水果。
有时也用“every+序数词+名词（单数）”，注意不要弄错了其中的名词的数。如：
奥林匹克运动会每四年办一次。
正：The Olympics are held every four years.
正：The Olympics are held every fourth year.
如果是表示“每隔一……”，则还可用every other…，如“每隔一天”可说成every two days, every second day, every other day (www.hxen.com)。
陷阱5 用错“另外几个……”的表达法
用英语用表示“另外几个……”的方法是：“another / a further +数词+名词”或“数词+ other / more +名词”。如：
Three other men lay wounded. 另外三个人受伤躺在那里。
Two other boys escaped through the trees. 另外两个小伙子从树林间逃跑了。
这类表达有时有较灵活的翻译。如：
I could go on for another two hours. 我再讲两个小时都讲不完。
They drove for another three hours. 他们又行驶了3个小时。
I need another few days before I can make up my mind. 我还需几天才能决定。
陷阱6 混淆数词的单复数形式
当要表示某人的大约年岁和世纪中的某个年代时，我们习惯上要用逢整“十”的基数词的复数形式，此时不可误用单数形式。如：
He left for
He began to write in his sixtieth. 他在六十多岁开始写作。
表示年代时，有时还会说出某个世纪，此时要使用类似以下这样的表达：
in the
since the 1950s 从20世纪50年代开始
