题目内容
12.Looking (look) up every new word in the dictionary will certainly be a waste of time.分析 在字典中查找每一个生词肯定是浪费时间.
解答 答案是Looking.本题来考查动名词做主语;题干中动词will be 前缺少的是主语;动名词做主语表示一般性的行为,动词不定式做主语表示具体的某一次行为;本题表示一般性行为,故用动名词Looking;
点评 本题是要求用所给动词的适当形式填空,解题时首先考虑句中需要的是谓语动词还是非谓语动词;其次,如果是谓语动词关注时态、语态和数的变化;如果是非谓语动词要联系非谓语的基本用法判断非谓语的形式.
