1.The Coast Guard says they will keep searching for survivors of victims of last night’s crash.

keep doing keep on doing

keep doing sth.和keep on doing sth.意义及用法相同,但后者更强调决心和重要性。如:

  He kept coughing all morning.他整个上午不停地咳嗽。

  He kept on phoning me, but I really didn’t want to talk to him.他不断给我打电话,但我实在不想和他说话。

  keep或keep on后跟表示动作的-ing形式,不可接动词不定式或表示静止状态的-ing形式,不能说He kept on to talk. 也不能说They kept on sitting.

2.uh, three helicopters, several ships now taking part in that search.

take part in参与,参加

例句:He was disqualified from taking part in the competition.
       他被取消参加该项比赛的资格。

3.US Secretary of State Hillary Clinton challenging Pakistan to do more to hunt down members of Al-Qaeda in that country, she said she finds it difficult to believe that no one in the Pakistani government knows where Al-Qaeda members are.

hunt down穷追…直至捕获,搜寻…直至发现

例句:The hounds will soon hunt down the stag.
      猎狗不要多久就会追到那头牡鹿。

      The police have hunted down the escaped prisoner.
      警方已经追捕到了那个逃犯。
