Step13Languagepoints

LetSsmasterthemainpointsofthepassage.

1）I’mpreparingsomenotesforareportcalled“Ourgrowingpopulation”.

prepare用作动词，意为“准备”，后面常跟名词、代词、不定式作宾语。

prepare…for…为……准备……

e.g.Heispreparingadinnerforhisfriends.

他正在为他的朋友准备晚饭。

2）Thatcausesalotofproblems,suchastoomuchtrafficandnoise.

toomany后面加可数名词，表示“太多的”。

toomuch后面加不可数名词，表示“太多的”。

e.g.Therearetoomanybooksinthebookshop.书店有太多书。

Thereistoomuchwaterontheground.地上有太多水。

3）Ican’tbelieveit!

表示“简直难以置信”。

表示一种惊讶。

4）ThepopulationofChinaisabout1.37billion.

billion（十亿）,million（百万）,thousand（千）都是数字单位。

前面有具体数字修饰时，用单数形式；billion还常用于固定结构billionsof,表示“数以十亿计的”。

与此用法类似的词还有hundred,thousand,million等。

e.g.Themanisveryrich.Hehasfivebillion.

那个男人非常富有。

他拥有50亿。

Therearebillionsofbooksinthebiglibrary.大图书馆有数以亿计的图书。

5）That’salmostonefifthoftheworld’spopulation,...

onefifth表示“五分之一”，fifth是序数词。

分数的表达：

分子用基数词，分母用序数词。

分子大于1时，分母+s。

e.g.2/5:

twofifths

6）Hangonaminute!

hangon通常用来表示让某人等一下。

e.g.Hangon!

I’llbebackinaminute.

稍等！

我马上回来。

Step14Grammar

掌握数字的用法。

朗读时，将每三位数看做一个单位，依次为billion，million，thousand。

每个单位按照百、十、个位向下读，其中百位到十位之间要加入and。

e.g.729：

sevenhundredandtwentynine.

6,500,431,729：

sixbillionfivehundredmillionfourhundredandthirtyonethousandseven

hundredandtwentynine.
