PopulationThepopulationofChinaisabout1.37billion第2課時

?problem與questionproblem和question都有“問題”的意思，但用法卻不盡相同：problem指說話者認為難以解決的問題，它與動詞solve或settle(解決)搭配。而question指說話者需要尋找答案的問題，它常與動詞ask或answer連用。?onefifth五分之一英語中分數(shù)表示法為：分子采用基數(shù)詞，分母采用序數(shù)詞且有單復數(shù)形式。分子大于1，分母要用復數(shù)形式。eg：oneseventh七分之一twosevenths七分之二?billion數(shù)詞，意為“十億”，當表示具體的“幾十億”時，用“基數(shù)詞＋billion”表示，注意此時billion不用加“s”。eg：tenbillionyuan一百億元【拓展】billionsof...表示“數(shù)十億”，這時billion后有s，且后面有介詞of，并且不能與數(shù)詞連用。?Hangon！等一等！hangon意為“(耐心)等待”。常用于口語交際，意為“打??；不要再說下去了”?！猈ecan'tdothis.Mymumsays...我們不能這么做。我媽媽說……—Hangon！You'reabigboy.Don'talwayssay“Mymumsays”．打??！你是個大男孩了。別總把“我媽媽說”掛在嘴邊?！咀⒁狻縣ang(懸掛)—過去式及過去分詞為hung；hang(吊死；絞死)—過去式及過去分詞為hanged?！就卣埂俊癏angon.”也是一句電話用語，表示“別掛斷”。
