Do you know how to pronounce this word yes,I_____in the dictionary yesterday.
A.looked it up B.worked it out C.gave it away D.picked it up
答：A
译：你知道这个单词如何发音吗?
是的.我昨天在词典中查过这个词.
析：look up a word in the dictionary 在词典中查一个单词.
如果是代词作动副词组look up的宾语的话,代词要放在副词up的前面.
work out是算出,give away是捐出,picu up是捡起,都不符合句意.
再问： 很好啦
