How___did he sleep?1.good 2.well 3.goodly 4.nice请说明理由

1.Are you good with children?
2.We need help for our school trip.
3.We want two singers for our rock band.

1 good是个形容词（adj.）而Well是个副词（adv）,形容词是用来形容名词的,比方说a good man（一个好人）,副词是用来形容形容词或者动词的,比方说,well done（干得好）
2 看空后面,you are ,所以说careful形容的是you,you are carefull,所以要用the more careful而不是the more carefully
如果说空后面写的是,you check out,那么就要用后者了.
3.both...and 表示两者都如何如何
neither...nor 表示两者都不如何如何
either...or.表示两者其中之一如和如何
not only...but also 表示不仅.而且
①both … and,either … or,neither … nor
both … and“双方都”,连接句子的两个主语时,其后谓语动词通常用使用复数形式.either … or与neither … nor注意采取“就近原则”.
②not only … but also,as well as
注意：两者强调对象不同,not only … but also强调的是but also之后部分,而as well as则强调其前面的部分.not only … but also采取“就近原则”,而as well as只是一个插入语,采取“就远原则”.如：
Mr.Smith,as well as his wife and children,has come to Nanjing for a visit.
not only … but also结构中的not only可用于句首,连接两个分句时,第一个从句主谓要倒装.
Not only is he clever ,but also he is hard working.
4.keep on doing,keep doing 一样的用法,都是保持（继续）做某事.

1. better
