答案:1. costs
解析:句子描述的是外套的价格,用一般现在时,主语“the coat”是第三人称单数,“cost”表示“花费”,第三人称单数形式是“costs”。
2. May
解析:“May I...?”表示“我可以……吗?”,是请求许可的常用表达,符合语境“我可以坐在这里吗?”。
3. believe
解析:“believe in”表示“相信”,“Do you believe in God?”意为“你相信上帝吗?”,所以填“believe”。
4. retire
解析:“be going to do sth.”表示“打算做某事”,“retire”意为“退休”,符合句意“伊恩先生很老了,他打算退休”。
5. worth
解析:“be worth doing sth.”表示“值得做某事”,是固定搭配,“This book is worth reading.”意为“这本书值得一读”,所以填“worth”。
6. because
解析:前后句是因果关系,“because”表示“因为”,符合句意“罗恩没去上学,因为他生病了”。
7. sold
解析:句子描述的是过去发生的事情,“sell...to...”表示“把……卖给……”,“sell”的过去式是“sold”,所以填“sold”。
