3. Lear the language pints.
(1) I’m preparing sme ntes fr a reprt called “Our grwing ppulatin”.
prepare … fr … 表示“为……准备……”。
(2) The ppulatin f China is abut 1.37 billin.
ppulatin 意为“人口”,用large 或small来修饰。 ppulatin是集合名词,没有复数形式,做主语时要用单数形式。
(3) That causes a lt f prblems, such as t much traffic and nise.
t much意为“太多”,其后接不可数名词。
辨析:nise, vice 与 sund
(4) That’s almst ne fifth f the wrld’s ppulatin, that is 7 billin.
ne fifth意为“五分之一”。表达分数时,用基数词表示分子,序数词表示分母。当分子大于1时,分母的序数词用复数。分数做主语时,谓语动词在数上与分数后的名词保持一致。
(5) The ppulatin f China is abut 1.37 billin.
billin 数词,意为“十亿”。在英语中,hundred, thusand, millin和billin前面有具体数字时,它们都要用单数形式;但是当与f搭配使用时,它们都必须用复数形式,表示概数,而且不能与具体的数字连用。
