媒體英語會(huì)帶大家一起學(xué)習(xí)BBC撰稿人在報(bào)道世界大事時(shí)常用到的單詞和短語。

Background: F1 也就是一級(jí)方程式賽車，因其動(dòng)力十足、昂貴和耗油的特點(diǎn)向來都不是一項(xiàng)與環(huán)保相關(guān)聯(lián)的運(yùn)動(dòng)。但是現(xiàn)在，一級(jí)方程式賽車的組織者宣布他們正在計(jì)劃減少這項(xiàng)比賽的碳排放量。

The Formula One Teams Association believes it can reduce carbon emissions by fifteen percent in the next three years.

A 'carbon audit' was carried out looking at every aspect of the sport, from the race weekend to the challenge of moving from country to country during the season.

Teams' buying in equipment was the largest contributor to carbon emissions. Moving to each race was anotherfactor, as was electricity usage - much of it to power wind tunnels to carry out aerodynamic testing.

Improvements may include rationalising the race calendar so that teams have shorter distances to travel.

Given that the cars themselves burn around one hundred and sixty litres of fuelduring each grand prix, it is perhaps surprising that racing and testing them counts for less than one percent of emissions.

Nonetheless rules may be changed from 2013, restricting the amount of fuel that teams can use, forcing the development of more efficient racing engines.

These moves to promote a more carbon conscious Formula One seem to be being driven by pressure from sponsors.

There are also hopes that the sport can become an attractive testing ground for more efficient technologies.
