第2个回答 2009-11-07
英语形容词比较级
(一)一般句式的构成： A + is / are+ 形容词比较级+ than + B
A 是主格 B 是宾格
如： She is taller than me.
主格 形容词比较级 宾格
（二）英语形容词比较级的构成
英语形容词比较等级有三个：原级，比较级和最高级。
形容词比较等级形式变化有规则的和不规则的两种。
规则变化
1）单音节词末尾加-er（比较级），-est（最高级）
【例】 原级 比较级 最高级
great greater greatest
small smaller smallest
clean cleaner cleanest
2）单音节如以e结尾，只加-r（比较级），-st（最高级）
【例】 fine finer finest
nice nicer nicest
wide wider widest
3）闭音节单音节词如末尾只有一个辅音字母，须先双写这个辅音字母，再加-er（比较级），-est（最高级）
【例】 big bigger biggest
hot hotter hottest
red redder reddest
4）少数以-y，-er，ow，-ble结尾的双音节词，末尾加-er（比较级），-est（最高级）。以-y结尾的词，如-y前是辅音字母，则变y为-i，再加-er和-est。以-e结尾的词只加-r和-st。
【例】 clever cleverer cleverest
narrow narrower narrowest
able abler ablest
easy easier easiest
5）其它双音节和多音节词皆在前面加单词more和most。
【例】 careful more careful most careful
difficult more difficult most difficult
delicious more delicious most delicious
不规则变化
原级 比较级 最高级
good/well better best
bad worse worst
many/much more most
little less least
far farther/further farthest/furthest
注：有些形容词一般没有比较等级。如： right, wrong, woolen等。
形容词的比较等级的用法：比较级用于二者的比较。
【例】 Li Ping is older than Wang Hai. 李平比王海年纪大。
There are more students in Class One than in Class Two.一班比二班学生多
1．把动词原形中的i改为a，变成过去式。如：
begin—began，drink—drank，give—gave，ring—rang，sing—sang，sit—sat，swim—swam
2．把重读开音节中的i改为o，变成过去式。如：
drive—drove，ride—rode，write—wrote
3．改动词原形中的aw ／ow为ew，变成过去式。如：
draw—drew，grow—grew，know—knew，throw—threw（动词show除外，show—showed）
4．动词原形中的e改为o，变成过去式。如：
get—got，forget—forgot
5．动词原形中的ee改为e，变成过去式。如：
feed—fed，meet—met
6．动词原形中的eep改为ept，变成过去式。如：
keep—kept，sleep—slept，sweep—swept
7．动词原形中的eak改为oke，变成过去式。如：
break—broke，speak—spoke
8．动词原形中的ell改为old，变成过去式。如：
sell—sold，tell—told
9．动词原形中的an改为oo，变成过去式。如：
stand—stood，understand—understood
10．以ought和aught结尾，且读音是〔 :t〕的过去式。如：
bring—brought，buy— bought，think—thought，catch—caught，teach—taught
11．以ould结尾且读音为〔ud〕的情态动词过去式。如：
can—could，shall—should，will—would
12．把动词原形中的o改为a，变成过去式。如：
come—came，become—became
13．在动词原形后加d或t变成过去式，并且发生音变。如：
hear〔hi 〕—heard〔h :d〕， say〔sei〕—said〔sed〕，mean〔mi:n〕—meant〔ment〕
14．动词的过去式与动词原形一样。如：
let—let，must—must，put—put，read—read〔red〕
15．不符合上述规律的动词过去式。如：
am，is—was，are—were，build—built，do—did，eat—ate，fall—fell，feel—felt，find—found，fly—flew，go—went，have ／has— had，hold—held，leave—left，make—made，may—might，run—ran，see—saw，take—took

(1) 过去完成时表示过去某时之前结束的动作或状态
When he got there, the train had already left.
他到了那儿时火车已经离开了。
Ina realized she had made a mistake.
艾娜意识到她犯了个错误。
(2) 过去完成时与when等从句连用
had+just / barely / hardly / scarcely+done...when..., no sooner...than... 是表示“刚……就……”或“不等……就……”的固定句型。如：
No sooner had we left the house than it began to rain.
我们刚离开家就开始下雨了。
I had not gone much farther before I caught them up.
我没有走多远就赶上他们了。
(3) 过去完成时表示持续到过去某时之前的动作或状态
We had finished the work by nine o'clock yesterday.
昨晚九点前我们已完成了工作。
The company had completed the project by the end of 1999.
到1999年底公司已完成了那个项目。
(4) 过去完成时表示未实现的愿望
过去完成时表示未实现的愿望的用法仅限于expect, hope, intend, mean, plan, think,want等动词，过去时间往往由一般过去时表达。如：
I had intended to speak, but time did not permit.
我本想发言，可是时间不允许。
I had hoped you might know. 我本希望你会知道的。
