英语数词中的定量表达和不定量表达

英语数词中的定量表达和不定量表达

在往常日子中,当咱们对人或事物进行计量时,有一种是用断定的数目表达的,如a/an或one标明“一”,two标明“二”,a(或one)hundred标明“一百”,three thousand 标明“三千”,four million 标明?陌偻颉保琭ive billion标明“五十亿”,这样的表达叫定量表达。还有一种是用不断定的数目表达的,如some/a few/several books 标明“几本书”,many/much/a lot of/lots of/plenty of/a large number of/a great

deal of都标明“许多的、许多的”,这些表达叫不定量表达。下面,咱们要说的是数词中的定量表达和不定量表达:

定量表达:如两百个学生,应表达为two hundred students,而two hundreds students 和two hundred of students和two hundreds Of students都是差错的表达。可是,two hundred of the students则是正确的表达(那些学生中的两百人),这是有些+of+全体的表达,与three of them/four of those boys/some of my friends是相同的表达。又如三千本书,大约表达为three thousand books,五万人大约表达为fifty thousand people,六百万工人大约表达为six million workers,十四亿人大约表达为one point four billion people。

不定量表达:如hundreds of students(成百上千的学生),thousands of books(不计其数的书),也可说成thousands and thousands of books。再例如millions of people(成百万的人),billions of people(数十亿的人)。至于不定量表达,前面不能加two/three/four这些定量词,如上面讲到的two hundreds of students

则是差错的表达,但前面可加some/many/a few/several这些不定量词,如可说many thousands of

students。留心不定量表达在hundred/thousand/million/billion后要加s,而且后边还要加上介词of,两者缺一不可以,如hundred of students和

hundreds students 都是差错的表达。

下面,让咱们来做以下标题(单项选择)

( )1.______people come to visit China every year.

A. Thousand B. Thousand of C. Two thousands of D. Many thousands of

( )2._______the students are from that country.

A. Three hundred of B. Three hundred C. Three hundreds D. Three hundreds of

上面的第1题大约选D,标明定量表达时,hundred/thousand/million/billion前面要加上a/an或数词one/two/three…,所以不能选A,而不定量表达要留心在thousand后边加s,而且加介词of,前面不能用定量词two,但可用不定量词many。

第2题大约选A,留心名词students前面有限制词the,归于有些+of+全体的表达。
