lighting,TV and the radio present the same proportion as do vacuum cleaners,food mixers

问题描述:

lighting,TV and the radio present the same proportion as do vacuum cleaners,food mixers
这是雅思小作文范文(十天突破雅思2 175页末)里的一句话,这里我觉得present 应该加S 因为范文里的当占有或相近意思的词都加了S 还有 这里的do 是怎么回事 我觉得应该去掉
范文中 lighting,TV and the radio makes up 17% of the need 这里make 加了s

我的那本书确实也这么印刷的,有点奇怪
我觉得要不都加s,要不都不加,
