過去式的變-ed

因為a,e,i,o,u後面要重覆一次
而plan裏的a 是a,e,i,o,u裏面其中之一
So plan的n要重覆一次
變成planned

有好多都係要變
例如:
dopped
......
......
......

因為A E I O U 係響音所以要雙N

e.g.
step stepped stepping
plan planned planning
hit hitting
run running

ok! It's a irregular verb. That's because pl"a"n, the a is a vowel. vowels are a,e,i,o,u
If a vowel comes before the last letter you need to double the last letter then add -ed.

ex: kidnapped

But there's always exception in English, which makes it hard to learn!



ex: needed, taped

因為a e i o u後面要變兩個加~~~
