在线英语句子改错急··几个句子改错不要在线翻译的 To my opinion,there are advantages

1.To my opinion中to 改为 in
in my opinion 是固定用法表示 “在我看来/以我的观点来看”,后引出观点】
2.Travel by plane 改为to travel by plane或traveling/travelling（“l”双写单写都可以） by plane
分析句意可知,Travel by plane 此时作主语,所以用动词不定式或V-ing形式,一般用V-ing形式】
3.but it is too expensive中it去掉
因为前面是逗号,这是一个小分句,与前句共用一个主语】
4.quite safety中safety改成safe
safe-形容词,safety-名词,safely-副词,注意区分】
5.sceneries改为scenery
scenery是可数名词,复数形式-sceneries但是它经常以单数形式出现.如：enjoying the varied mountain scenery.欣赏不同的山景.
您可以通过如下词语来理
abscence
clothing
film
help
furniture 家具
