英語六級-完形語法關(guān)鍵句399. Companies could also reduce prices for th

399. Companies could also reduce prices for those who stayed to eat food on their premises, offer money-off vouchers (代金券) or other incentives for those who returned packaging and put more bins at strategic points in local streets, not just outside their premises.

譯文　公司還可以給那些在經(jīng)營場所用餐的消費(fèi)者減價，為那些送回包裝的人提供代金券或其他鼓勵，同時在街道的關(guān)鍵位置放置更多的垃圾箱，而不僅僅是在他們的營業(yè)場所外。

點睛　本句的主干是Companies could also reduce..., offer...and put...。who stayed to eat food on their premises和who returned packaging均為定語從句，修飾各自前面的those。premises意為“場所，經(jīng)營場址”。如：

Beverages sold in this restaurant can only be drunk on the premises. 此餐廳的飲料只供堂飲。

reduce prices表示“減價”，money-off意為“減價，打折”，off本身也可表示這個意思，這時，其前面可以加打折的百分比。如：

All shirts have 10% off. 襯衫一律九折。

bin意為“（垃圾）箱”，垃圾箱也可以說dustbin或rubbish can。
