题目内容
5．这部电影很受青少年们的欢迎，已在当地的影院放映好几个星期了．The film，which is popular among teenagers，has been on forseveral weeksat the local cinemas．
分析 has been on for several weeks
解答 答案：has been on for several weeks．
首先通过中英文句子的比对，可知英文句子中缺少"已经放映好几个星期了"的表达．首先结合句意判断用现在完成时，构成是：主语+have/has+动词的过去分词，短语"放映"的英文表达是：be on （可以跟时间段连用）．时间状语"好几个星期"用for several weeks，本句的主语the film是第三人称单数，助动词用has，故答案为：has been on for several weeks
点评 做这类题型，首先根据所给汉语明确句子所要考查的单词或短语的拼写，再结合相关语法知识对单词或短语做出形式上的变化．
