这个open呢,这个也是辅元辅哦
很简单地说:就是一个单词无论多长,在考虑是否“双写”时,只需要看最后3个字母即可--即如果最后3个分别是由“辅元辅”(辅音,元音,辅音)构成的话,那么这个单词就需要“双写”,如果不是,那么就不用了。
但是有一个单词是例外,就是listen这个单词,虽说结尾3个字母符合“辅元辅”规则,但是这个单词却不双写,而是listening.
*重读闭音节三要素:
(1). 必须是重读音节;
(2). 最后只有一个辅音字母;
(3).元音字母发短元音 如:begin ,ap/ple a p 就是一个闭音节
2、以-al,-er,-ill,-el结尾的动词,即使重音不在最后一个音节上,也要双写,再加-ing 如:travelling等。
3、在最后一个字母不是A E I O U其中一个时,而最后一个字母的前一个字母是A E I O U(元音)其中一个时,就要双写最后一个字母,但如果而最后一个字母的前一个字母的前一个字母是元音的话就不能双写最后一个字。比如说: forget- forgetting travel- travelling.
我们老师说就像汉堡包一样结构:辅音+双元音+辅音
