The evening news comes on at seven o'clock and __ only thirty minutes.
A.keeps B.continues C.finishes D.lasts

答案:D

请问高手,本句为什么选D,如果选A或者B为什么不可以?

1、last①持续、继续…,如:
The flowers show lasted a week. 花展持续了一周。
②支持、保持、耐久,如:
How long will this battery last?
2、keep ①保持、保留(存),如:
He may keep the book until you come back.
②保有
You can keep it if you like it.
③饲养(动物)、抚养(家属)、雇佣(仆人)、收留(住宿者),如:
She has kept the cat these ten years.
3、continue①(continue是不间断的继续,而last 是中断、间断时又继续,如:
This road continued for miles.
②The rain continued three days.

这道题的题意是晚间新闻只有半个小时的播出时间 所以选D

LAST的意思是持续,说某事情持续了多长的时间.
CONTINUE是继续的意思,KEEP是保持的意思.

keep是保持的意思,continue是继续,last是持续,根据题意就知应选D
