题目内容
9.He has already found something unusual about the colourful birds.(改为否定句)Hehasn't foundanything unusual about the colourful birds yet.
分析 --他已经发现了一些关于五颜六色的鸟的不寻常的事情.
--他还没有发现五颜六色的鸟的任何不寻常的事情.
解答 答案:hasn't; anything.考查否定句.根据has already found已经发现,可知应该是现在完成时态,变否定句直接在助动词has后加not,缩写为hasn't.something否定句改为anything.答案是hasn't; anything.
点评 考查否定句.通常是在be动词,情态动词后加not.一般现在时态,主语不是第三人称单数用don't,主语是第三人称单数用doesn't.一般过去时态用didn't.还有其它用法需要牢记.
