　　 There's something rotten in Rio and the smell is coming from the huge stacks of rubbish pried up on sidewalks all over the city. Rio's street sweepers chose the carnival holiday to demand better salaries. Their wages start at roughly $400 a month.

　　 There could hardly be a better time for them to prove their importance. The streets were left a mess after hundreds of carnival parades and now, rubbish pries up in both poor and uptown neighbourhoods and in tourist areas like Ipanema or Copacabana beach.　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

　　 The president of Rio's rubbish collecting company has even appealed to the population to store rubbish at home whenever possible. He says 30% of the city's sweepers have gone on strike. Some of those who have been working have been threatened by the strike movement so now the police has been deployed alongside rubbish collectors to keep them sage as they go about their business.

　　 The strike has divided opinions in Rio. On social media, many support the sweepers' demands for better salaries. Others say they are opportunists and the situation is a big embarrassment to the city.

　　 But Brazil's culture of littering the streets doesn't help. A video that went viral online shows that even authorities have a problem with that. Rio's mayor, Eduardo Paes, is seen throwing what seemed to be the rest of an apple on the sidewalk--and now promised to impose himself a fine for his wrongdoing. His government recently created a programme to keep Rio's residents from littering the streets.

　 A. prove their importance　　　　　　　　　　　　 B. threaten the government

　 C. ask for higher salaries　 　　　　　　　　　　　　D. appeal to the public not to litter

2. There's a move towards indoor rides where the experience is improved by audio-visual technologies.

[翻译]对于乘坐过山车有一个在室内的趋势，在这里可以通过视觉技术来改善这个经历。

[分析]本句中的where the experience is improved by audio-visual technologies是一个由关系副词where引导的定语从句，修饰前面的先行词move趋势；因为后面的句子结构很完整，所以要使用关系副词来引导这个定语从句，where通常前面的先行词都是表示地点的名词，但是有时候表示抽象概念的名词，如stage等也可以使用where来引导。

1. while we may have reached the limit in terms of G-forces, there is no technological limit to how fast or how high roller coasters can go---it's all down to money.

[翻译]尽管我们在G-force方面到达了极限，但是在过山车的速度方面却没有技术方面的限制，这都取决于钱。

[分析]本句中的连词while表示“尽管”，引导的是一个让步状语从句，相当于although。While有多种含义：当…时（与延续性动词连用）；然而（表示轻微的转折）。
