【题目】Excused from recycling(回收利用)because you live in a high rise with a rubbish chute(垃圾滑道)? You_won't_be_for_long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too.

In Shantzis' HiRise Recycling System, a chute leads to pieshaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal and other rubbish to go into separate boxes.

The system is controlled from a board fixed next to the chute door. The board has a button for each class of recycling materials(as well as for un-recyclables). At the press of a button, a microcomputer locks all other floor's chute doors and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables.

Sorting(分类)recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted! Shantzis believes his system could help recycled materials become more costeffective.

【2】D

【3】C

【4】A

【解析】【1】本题考查对文章主旨进行推测概括的能力。本文由四段组成。第一段主要说明了excused from recycling的原因。第二段说明了the system的组成。第三段说明了the system的控制。第四段说明了the system的用途。通过对全文的分析，可以很明确地得知贯穿全文的主旨内容是B项的内容。

【2】略

【3】本题考查根据文中具体的内容进行分析概括的能力。从第三段“The system is controlled from a board fixed next to the chute door. The board has a button for each class of recycling materials...a microcomputer locks all other floors' chute doors and sets the recycling container turning until the right box comes under the chute”可知正确答案为C。

【4】本题考查对文中所给信息进行推理判断的能力。文章的最后一段中所给的信息就告诉了我们这一题的答案。由“Shantzis believe his system could help recycled materials become more costeffective”可知这一新系统最大的优点是节约回收利用的成本。
