形容词、副词的比较级
教学建议:
比较级常用的句型结构是重点。
【知识梳理3】
1.可以修饰比较级的词:
much,alot,far,表示“…的多”;alittle,abit,表示“…一点儿”;
even甚至,still仍然。
LessonOneismucheasierthanLessonTwo.
Tomlooksevenyoungerthanbefore.
Thistrainrunsmuchfasterthanthatone.
Shedrivesstill/far/muchmorecarefullythanherhusband.
2.比较级常用的句型结构
(1)(倍数)比较级+than,表示“甲比乙…”或“甲比乙…几倍”
TomistallerthanKate.
Thisroomisthreetimesbiggerthanthatone.
Igotupearlierthanmymotherthismorning.
Herunsthreetimesfasterthanhisbrother.
(2)表示不同程度比较时,句子主语不能包括在比较对象的范围之内。
例如:
TheYangtzeRiverislongerthananyotherriverinChina.
=TheYangtzeRiverislongerthananyoftheotherriversinChina.
=TheYangtzeRiverislongerthantheotherriversinChina.
=TheYangtzeRiveristhelongestriverinChina.
Hestudiesharderthananyotherstudentintheclass.
Hestudiesharderthananyoneelseintheclass.
Hestudiesharderthanalltheotherstudentsintheclass.
注意①:
TheYangtzeRiverislongerthananyriverinJapan.长江比日本的任何一条河都长。
(因为长江不是日本的,所以它要比日本境内的任何一条河都长,这里就不用加other),又如:
Themoonisclosertousthananystar/stars.月亮距离我们比任何恒星都近。
(月亮不是恒星,因此用anystar/stars并没有把主语包括在比较对象的范围之内)
ChinaislargerthananycountriesinAfrica.中国比非洲的任何国家都大。
ChinaislargerthananyothercountryinAsia.
中国比亚洲的任何国家大。
(中国是亚洲国家之一,因而不能用anycountries)
注意②:
anyother加可数名词单数,alltheother加可数名词复数。
试比较:
例如:
Mikegetstoschoolearlierthananyotherstudentinhisclass.
=Mikegetstoschoolearlierthananyoftheotherstudentsinhisclass.
=Mikegetstoschoolearlierthan(all)theotherstudentsinhisclass.
=Mikegetstoschoolearliestinhisclass.
注意③:
MikegetstoschoolearlierthananystudentinTom’sclass.
迈克比汤姆班上任何一个学生到校都早。
(迈克和汤姆不是同一个班)
(3)比较级+ofthetwo,表示“甲是两者中较……的”
Lookatthetwoboys.Mybrotheristhetallerofthetwo.
