Question

【題目】Breakthroughs in science and technology are paving the way for modern cities to support bigger populations. Now, we see the most exciting urban innovations to show you exactly how they’ll improve your city’s infrastructure(基礎(chǔ)設(shè)施).

Lighting Up The Night

Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill (填充物) that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees’ swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees’ outer LEDs.

Thinking Outside The Box

As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents’ health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended(懸浮的) roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition.

Waving Hello To Clean Energy

Cities that don’t receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption(中斷), electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs.

【1】What is the special infill used to do?

A. To make the trees beautiful.

B. To produce electricity.

C. To help the trees’ swaying.

D. To collect water from rainfall.

【2】How do the Netherlands improve the city traffic according to the text?

A. By updating the city roadway condition.

B. By building walking passages underground.

C. By creating suspended roundabouts above roadways.

D. By supporting more biking and walking.

【3】What does the author mainly tell us in the last paragraph?

A. The advantages of wave power.

B. The ways to use wave power.

C. The future of wave power.

D. The advances in wave power technology.

Answer 1

【答案】

【1】D

【2】C

【3】A

【解析】

試題分析：科技的突破給人們的生活帶來了很多的方便，本文主要介紹三種不同的科技給城市帶來的便利。

【1】D 細節(jié)理解題。根據(jù)第二段中“These electric trees contain a special infill (填充物)that collects water from rainfall.”可知，答案為D。

【2】C 細節(jié)理解題。根據(jù)第三段中“One way to achieve this is by updating infrastructure to support biking and walking by building suspended roundabouts like hovering in the Netherlands.”可知，答案選C。其中A、B、D三個選項雖然是改善交通狀況的途徑，但不是文章中the Netherlands 的做法，因此選C。

【3】A 主旨大意題。最后一段主要講述的是wave power的好處。一個就是海浪永遠不會枯竭，另外就是wave power的技術(shù)快速發(fā)展，可以把發(fā)電機安放在深海區(qū)域，讓發(fā)電機組可以高速運轉(zhuǎn)。因此選A。而D答案不能概括段落所有的意思，所以不能選。
