22、on，its return was _10.a_ wonder.文章大意：本文讲述了主人公Pahlsson在一个胡萝卜的茂密的叶子下面，找到了她遗失很久的结婚戒指。16年前Pahlsson在厨房做饭时取下戒指，之后戒指就找不到了。而16年后花园中胡萝卜的意外发芽使戒指又被找回。他们现在认为戒指可能和一堆厨房垃圾被扫到花园中了。戒指的失而复得对他们来说是个奇迹。解析：1考查名词复数。句意：Lena Pahlsson拔出一把小胡萝卜正要扔掉。a handful of意为“一把，几个”，后加可数名词复数形式。故填carrots。2考查形容词。句意：她注意到一个闪亮的物体。由语法知识可知，形容词修饰名
23、词object。故填shiny/shining。3考查固定结构。句意：Pahlsson大声地喊叫以至于她女儿从房子里跑出来。so.that.意为“如此以至于”。故填so。4考查反身代词。句意：她认为我伤到了我自己。由语境可知，女儿听到母亲的叫声后跑出门，以为母亲伤到了她自己。myself是反身代词，指“我自己”。故填myself。5考查固定用法。由语境可知，这个戒指是十六年前丢的。数词years earlier表示“年前”。故填earlier。6考查非谓语动词。句意：Pahlsson把钻石戒指摘掉去做饭。这里用不定式表目的。故填to cook。7考查时态。句意：Pahlsson和她的丈夫在厨房
24、寻找。由语境可知，这段是她回忆戒指丢失时的场景，故谓语动词需要用过去时。故填searched。8考查语态。句意：Pahlsson和她的丈夫现在认为戒指可能和一堆厨房垃圾被扫到花园中了。由语境可知，戒指是被扫到花园中，故空白处填被动形式。故填swept。9考查定语从句。句意：Pahlsson和她的丈夫现在认为戒指可能和一堆厨房垃圾被扫到花园中了，在那里直到胡萝卜意外地发芽使戒指通过绿叶又被找到。前后两句很完整，由句意可知，后半句是对花园进行了进一步的解释说明。故后半句是定语从句，先行词是garden，关系副词where在从句中作地点状语。故填where。10考查冠词。句意：它的回来(指戒指失而复
25、得)是一件很奇妙的事。wonder在这句话中的词性是名词，可数名词单数前需要加冠词。故填a。.读后续写阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。A friend of mine whose name was John Smith had a bad memory，which made him famous.He was so forgetful that he sometimes forgot what he was talking about in the middle of a sentence.His wife had to co
