仁爱英语八年级Unit1Topic2重点知识点讲解例题讲解课后练习
Topic2Whathashappenedtothepopulation?
1.--Ireallyhatetogosuchaplace.我真讨厌去那样的地方。
--SodoI.我也是。
SodoI.为倒装句,表示前面提到的肯定情况也同样适合另外一个主体,表“某某也一样”,结构为“so+be/情态动词/助动词+主语”。
eg:
Jimisastudent,soisTom.吉姆是一名学生,汤姆也是。
Jimcanswim,socanTom.吉姆会游泳,汤姆也会。
Jimlikessports,sodoesTom.吉姆喜欢运动,汤姆也喜欢。
如表前面不怎样,后面“也不”怎样时,其结构为“neither/nor+be/情态动词/助动词+主语”。
eg:
Jimwasn’tChinese,neither/norwerethey. 吉姆不中国人,他们也不是。
Jimcan’tspeakJapanese,neithercanI. 吉姆不会说日语,我也不会。
Jimdidn’tgothere,neitherdidI. 吉姆没去那儿,我也没去。
如前后两句表达的是同一个主体,则不能倒装,表“的确如此”。
如:
eg:
Jimisagoodstudent.Soheis.吉姆是一名好学生,的确如此。
Jimswimswell.Sohedoes.吉姆游泳很好,的确如此。
2.Atthattime,Chinawasthecountrywiththelargestpopulationintheworld.那时,中国是世界上人口最多的国家。
population为不可数名词,表示人口的多少只能用“large”或“small”修饰,提问人口用“what”,如:
eg:
ThepopulationofShanghaiislargerthanthatofBeijing.
What’sthepopulationofChina?
=HowmanypeoplearethereinChina?
3.GreatchangeshavetakenplaceinChina.中国发生了巨大变化。
takeplace指必然性的“发生”或有计划、安排之内的“举行”。
如:
eg:
ThemeetingwilltakeplacenextFriday.
happen指偶然的、没有预料的“发生”,其结果往往给人带来不幸或麻烦。
如:
eg:
Theaccidenthappenedyesterday.
※两者都不用于被动语态。
4.Thepopulationhasincreasedalot.人口增长发很多。
increase可作及物动词也可作不及物动词。
其含义是“增长,增加,加强”等。
increaseby…指“增加了……”;
eg:
Theaveragesalarydoesindeedincreaseby10%.
平均工资实际上增加了10%。
increaseto…指“增加到……”
DollarspendingonMedicarepatientswouldincreasetooveratrilliondollarsby2020.
到2020年,为享受医保的病人所投入的金额将增长到一万亿美元。
Thefourthweek,stayat4times,butincreaseto35-40minutes.
第四周走四次,但是增加到35-40分钟。
5.…andaboutonefifthofthepeopleintheworldliveinChina.
而且世界上大约五分之一的人口生活在中国。
onefifth是分数表达法。
英文分数表达法:
分子为基数词,分母为序数词,先读分子后读分母。
当分子大于1时,分母的序数词则变为复数,直接在词尾加“s”。
eg:
onefourth四分之一;threefourths四分之三;
onesecond二分之一;twothirds三分之二
注:
分数修饰名词作主语,谓语动词要和所修饰的名词保持一致。
6.IthasworkedwellincontrollingChina’spopulation.

9.Ican’tgoshoppinginbigstoresunlessItravelforacoupleofhours.我得花几个小时,才能到大的商场购物。
