英語六級-聽力口語關鍵句44.在一位匿名來電者向警方打電話后

44. Following a telephone call to the police from an anonymous caller, hundreds of shoppers were shepherded out of the store while roads in the area were sealed off.

點睛　

follow此處意為“在……之后”，其現(xiàn)在分詞形式引導句子的狀語。anonymous意為“匿名的”。be shepherded out of意為“從……中被引導出來”，shepherd此處為動詞，本身含有“帶領，引導；護送”之意。如：
The super star came in, shepherded by her guards. 這位超級巨星在保鏢的護送下進來了。
seal off意為“封鎖，封閉”。
