托?？谡Z(yǔ)第二題環(huán)境類話題：城市交通擁堵如何應(yīng)對(duì)

　　Firstly, there is a need to expand, to build more roads and bridges to accommodate the growing number of people and cars. There are now fifty times as many cars on the roads as there were in the 1970s. Broadening existing roads into multi-lane overpasses in both the city center and suburbs could help to relieve traffic-related stress in city centers.

　　In addition, we should redesign the transportation system. Rapid urbanization demands that we rethink and be innovative. Imagine a system in which real-time information is gathered to move buses, cars and trains with maximum efficiency. Smart tickets count commuters on the subway. Sensors embedded in roads enable live feeds of traffic conditions. This sophisticated monitoring system helps to keep road traffic flowing above ground.

　　這是一個(gè)具有全球性影響的問(wèn)題。下面是一些我們可以解決這個(gè)問(wèn)題的方法。

　　首先，需要擴(kuò)大，修建更多的道路和橋梁，以適應(yīng)越來(lái)越多的人和汽車。與上世紀(jì)70年代相比現(xiàn)多出了五十倍多的汽車在道路上。在城市中心和郊區(qū)把現(xiàn)有道路拓寬為多車道的立交橋可能有助于緩解城市中心的交通壓力。

　　此外，我們還要重新設(shè)計(jì)交通運(yùn)輸系統(tǒng)?？焖俚某鞘谢笪覀冎匦滤伎己蛣?chuàng)新。設(shè)想一個(gè)系統(tǒng)，它可以實(shí)時(shí)收集信息，以最大限度地提高公共汽車、汽車和火車的運(yùn)行效率。智能票在地鐵上計(jì)算通勤人數(shù)。道路上的嵌入式傳感器可以對(duì)交通狀況進(jìn)行實(shí)況轉(zhuǎn)播。這種先進(jìn)的監(jiān)控系統(tǒng)有助于保持道路交通暢通。
