外電報(bào)道如下：Sri Lankans cremated their assassinated foreign minister Monday as the government urged the international community to clamp down on overseas supporters of Tamil rebels amid fears the killing could scuttle a three-year-old cease-fire.
句中的clamp down on表示"施壓于；壓制；限制；對(duì)……進(jìn)行取締"的意思。例如：The government is clamping down on teenage drinking.（政府正在禁止青少年飲酒。）Following the military coup, there has been a clampdown on press reporting in the capital.（軍事政變以后，對(duì)首都的新聞報(bào)道進(jìn)行壓制。）
