2015年职称英语考试已经开始备考,本阶段应该多整理一些基础词汇和语法,为此,医学全在线网站特整理了“2015职称英语卫生类语法辅导汇总”供您参考,希望对您有帮助!
单位词的使用
(1)不可数名词表示多少,一般用much,(a)little,a lot of,enough 等词表达,要数1,2,3,4…时要用“量词”表达,最常用的是a piece of(news,advice,furniture,information…)
(2)成双成对的名词一般用复数,如:a pair of trousers(裤子)/scissors(剪刀)/glasses(spectacles)(眼镜)/pliers(钳子)
(3)a couple of表示一对,或2-3…,如:a couple of days /people /things
(4)记住以下量词表达方式:
a loaf(two loafs)of bread(一个(两个)面包)
a burst of laughter(一阵笑声)
a fit of anger /chill(一阵发怒 /发冷)
a game of chess(一盘棋)
a lump of sugar(一块方糖)
10、其他应注意的数的表达形式
1)a three-year-old boy 比较The boy is three years old
2)five thousand people /several thousand people比较 thousands of people
表达具体数字时,thousand不加"s”,后面不加"of ”;ten,million,billion情况以此类推。
3)One-third of the students have passed College English Test Band IV.
Two-thirds of the students have passed College English Test Band IV.
One-third of the population in this area is living below the poverty line.
(这个地区有1/3人口生活在贫困线以下。)
注意:几分之几的表达形式;动词的单复数由后面的名词数决定。
4)a looker-on 比较two lookers-on(旁观者)/a brother-in-law比较two brothers-in-law(姻亲兄弟)
5)my father,together with(along with /with /as well as my mother and brothers)结构中,主语作单数处理,即my father.
