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.

六級詞匯講解:
follow此處意為“在……少后”,其現(xiàn)在分詞形式引導(dǎo)句子的狀語。anonymous意為“匿名的”。be shepherded out of意為“從……中被引導(dǎo)出來”，shepherd此處為動詞，本身含有“帶領(lǐng)，引導(dǎo);護(hù)送”之意。如:
The super star came in, shepherded by her guards.
這位超級巨星在保鏢的護(hù)送下進(jìn)來了。
