为什么draw变ing形式的时候不需要双写w

2022-08-14 教育 103阅读
draw不是重读闭音节的单字,aw连起来发一个长元音,所以它不双写w再加-ing,而是直接加-ing。
现在分词一般由动词原形加-ING构成。如:
go—going
ask—asking
study—studying
see—seeing
stand—standing
answer—answering
be—being。
但在下列情况下,拼写应作相应变化:
以不发音的-e结尾的动词,须去掉e再加-ING。如:
come—coming
take—taking
write—writing
become—becoming
但当将-e去掉会引起发音变化时,最后的-e应保留,如:
singe—singeing
tinge—tingeing
›另外,-e前为元音(u除外)时,-e也应保留,如:
canoe—canoeing
hoe—hoeing
toe—toeing
dye—dyeing
eye—eyeing
shoe—shoeing
agree—agreeing
see—seeing
flee—fleeing
free--freeing
如果-e前面的元音字母为u,则-e要去掉:
pursue—pursuing
sue—suing
construe—construing
imbue—imbuing
clue—cluing
glue—gluing
blue—bluing
cue—cuing
动词是闭音节的单音节词,或是以重读闭音节结尾的多音节词,末尾只有一个辅音字母(包括r,但x除外)时,这个辅音字母须双写,然后再加-ING。如:
sit—sitting
run—running
stop—stopping
begin—beginning
admit—admitting
forget—forgetting
fix——fixing。
少数几个以-IE结尾的单音节动词,须变IE为y,再加-ING,如:
die—dying
lie—lying
tie—tying。
