题目内容
16．The Greens are lying on the beach and they feel reallyrelaxed （relaxing，relaxed）分析 格林一家人正躺在海滩上，他们觉得确实很放松．
解答 答案：relaxed．
以-ed结尾的形容词经常用来修饰人，或者用人来作主语；以-ing结尾的形容词经常用来修饰物．根据"they feel really____"可知主语是they，所以要用以-ed结尾的形容词来作表语，故选relaxed．
点评 首先要掌握-ed结尾和-ing结尾的形容词的用法区别，然后结合具体的英语句子以及给出的英语提示，就可以确定正确答案．
