题目内容
5．My friend likes films about cowboys．（改为否定句）My frienddoesn't like films about cowboys．
分析 我的朋友喜欢关于牛仔的电影．
我的朋友不喜欢关于牛仔的电影．
解答 答案：doesn't like．原句中实意动词likes得知是一般现在时，转换成否定句时借助于助动词，my friend是第三人称单数，故用does not，缩写为doesn't，助动词后应跟上动词原形，故答案是doesn't like．
点评 本题考查肯定句变否定句，做此类题时，需在句子相对应的助动词后加not，若动词为三单或过去时，动词需还原成原形．
