the shops （cut the price ）for the old clothes (as for) food

1 the shops （cutting the price for the old clothes (as for) food for the party,i have prepared it.
这句的谓语动词是后面的have prepared ,所以前面的动词只能作定语,用cutting ,
as for 是介词短语,没有变化形式,表示“至于.关于...”
2 the restaurant has a( better service) so i often eat there
这是表示因果关系,那家餐馆提供更好的服务,所以我经常在那里吃.
我认为填better 更好,如果你要填good 也不算错就是
