摘要：交通當局周四表示，北京明年將繼續(xù)通過搖號來限制車輛注冊以控制道路車輛數(shù)量。你知道怎么用英語表達嗎?

　　Beijing will continue to limit new vehicle registrations through a lottery system next year to hold down the number of vehicles on the road, the transportation authority said on Thursday.

　　Li Xiaosong, deputy director of the Beijing Municipal Commission of Transport, told a news conference on Thursday that granting car registrations via a lottery system is an effective way to prevent the number of vehicles from rising quickly.

　　The measure was introduced in 2011 to cap new car ownership at 240,000 a year.

　　交通當局周四表示，北京明年將繼續(xù)通過搖號來限制車輛注冊以控制道路車輛數(shù)量。

　　北京市交通委員會副主任李曉松在周四的新聞發(fā)布會上說，購車搖號是阻止車輛增長過快一個有效方式。

　　2011年購車搖號政策開始施行，為了將每年的新車數(shù)量控制在24萬輛。

　　【講解】

　　“購車搖號”在文中的表達為car/vehicle registration through/via a lottery system，car/vehicle registration是“車輛登記”，lottery意為“抽獎給獎法，彩票”，如football lottery(足彩)，welfare lottery(福彩)。文中第一句里hold down這個短語意思是“壓低，使不上漲”，最后一句中的cap作動詞，意為“限制(數(shù)量)”。
