摘要：伦敦当地时间8月6日晚发生的骚乱已蔓延至伯明翰、利物浦、诺丁汉和曼彻斯特等多个城市。由于首都伦敦加强了警力，主要大街遍布全副武装的防暴警察，目前事态已经趋缓。你知道怎么用英语表达吗?

British Prime Minister David Cameron recalled Parliament from its summer recess Tuesday and nearly tripled the number of police on the streets after three days of rioting in London blossomed into a full-blown political crisis.

Cameron described the scenes of burning buildings and smashed windows in London and several other British cities as "sickening", but refrained from more extreme measures such as calling in the military to help beleaguered police restore order.

A wave of violence and looting has raged across London since Saturday, as authorities struggled to contain the country's worst unrest since race riots set the capital ablaze in the 1980s.

周二，英国首相卡梅伦结束暑期休假，重新召集议会。伦敦骚乱发生三天后发展成全面的政治危机，街头的警察数量也增加为原来的三倍。卡梅伦称，伦敦等城市街头被烧毁的建筑物、街上的碎玻璃等景象令他恶心，但是没有要求采取更极端的措施，如召集军队协助被围攻的警察恢复秩序。从6日开始，伦敦发生了一系列暴力和劫掠事件，这是自上世纪80年代伦敦种族骚乱以来英国历史上最严重的动乱，英国当局在努力抑制骚乱。

【讲解】文中的riot即指骚乱，原本在伦敦北部城镇托特纳姆(Tottenham)举行的示威活动(demonstration)突然演变为暴力(violence)事件，并逐渐蔓延至多个城市。Riot police指防暴警察，riot gear指防暴服，Rioter则表示骚乱分子、暴乱者的意思。文中的unrest也有动乱，骚乱的意思，looting是指抢劫、劫掠。
