补充说明

despite its importance，thereby causing wasteful spending状语
there主语
is谓语
no denying宾语
that every now and then,advertising leads consumers into an impulsive perchase,跟着denying的东西，叫什么从句忘了
every now and then从句的时间状语
advertising从句主语
leads...into是advertising的谓语，consumers是其宾语，an impulsive perchase应该是宾补吧。
分是没问题，但叫什么忘的差不多了。

主干是there is no denying thatadvertising leads consumers into an impulsive perchase
despite its importance做的是让步状语
every now and then做的是时间状语
thereby causing wasteful spending.做的是目的状语
译为：即使广告很重要，但不能否认它会促进购物潮，为此造成不必要的花费

there is no denying that advertising leads consumers into an impulsive purchase.是句子主干 that后面是同位语
despite its importance 让步状语
thereby后面是结果状语
