我来补答
【以下全是自己的总结,记录在我的记事本中】
元音字母有:a,e,i,o,u,五个,其余为辅音字母.
1.规则动词的过去式
a)一般情况下动词词尾加-ed:
work--->worked,play--->played,watch--->watched
b)以不发音的-e结尾的动词,动词词尾加-d:
live--->lived,move--->moved,hope--->hoped
c)以辅音字母+y结尾的动词,把-y变-i再加-ed:
study--->studied,cry--->cried,carry--->carried
d)一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母再加-ed:
stop--->stopped,drop--->dropped.plan--->planned
2.不规则动词的过去式
a)把动词原形中的i改为a:
begin--->began,drink--->drank,give--->gave,sing--->sang,
sit--->sat,swim--->swam
b)把动词原形中的i改为o:
drive--->drove,ride--->rode,write--->wrote
c)把动词原形中的aw/ow改为ew:
draw--->drew,grow--->grew,know--->knew(动词show除外,show--->showed)
d)过去式以ought和aught结尾:
bring--->brought,buy--->bought,think--->thought,teach--->taught
e)将动词原形后的d改为t:
build--->built,spend--->spent,lend--->lent,send--->sent
f)含双写字母的动词将双写改为单写再在词尾加t:
keep--->kept,sleep--->slept,feel--->felt,smell--->smelt
g)动词的过去式与动词原形相同:
let--->let,put--->put,read--->read,hit--->hit,cost--->cost
h)没有规律的动词过去式
2.现在分词构成
在一般情况下在动词词尾加ing,如:
play--->playing,do--->doing,watch--->watching,talk--->talking
以不发音的e结尾的动词,去掉e加ing,如:
have--->having,take--->taking,live--->living,write--->writing,dance--->dancing
注意:如果单词词尾的e发音,则不能去掉,那么直接在后面加ing,如:
see--->seeing,agree---agreeing
以ie结尾的动词,把e改为y再加ing:
die--->dying,lie--->lying,tie--->tying
以一个辅音字母结尾的重读闭音节需要双写尾字母再加ing
a)begin--->beginning,plan--->planning,win--->winning,run--->running
b)hiccup--->hiccupping,chop--->chopping,drop--->dropping,
stop--->stopping,shop--->shopping
c)shut--->shutting,cut--->cutting,chat--->chatting,get--->getting,
hit--->hitting,spit--->spitting,put--->putting,sit--->sitting,
babysit--->babysitting,set--->setting
d)trek--->trekking,swim--->swimming
travel--->travelling/traveling
