The brave childspent two hours saving his parents by himself until the firefighters arrived in the ruins of the earthquake．

Answer 1

分析 spent two hours saving his parents by himself until the firefighters arrived．

解答 答案：spent two hours saving his parents by himself until the firefighters arrived．这里是说过去的事情用一般过去时，主语是the brave child是人，表示花费时间做某事用spend+时间或金钱+doing sth，spend的过去式是spent，两小时two hours，救他的父母save his parents，独自的by himself，直到用until引导时间状语从句，主语是the firefighters，到达arrive，过去式arrived，故答案是spent two hours saving his parents by himself until the firefighters arrived．

点评 spend，cost，take和pay的区别是历年中考试题的必考内容之一，虽然它们都可以表示"花费"，但用法却不尽相同．
spend的主语必须是人，常用于以下结构：（1）spend time/money on sth．在…上花费时间（金钱）．例：I spent two hours on this maths problem．这道数学题花了我两个小时．（2）spend time/money （in） doing sth．花费时间（金钱）做某事．例：They spent two years （in） building this bridge．造这座桥花了他们两年时间．cost的主语是物或某种活动，还可以表示"值"，常见用法sth．costs （sb．）+金钱，某物花了（某人）多少钱．例：A new computer costs a lot of money．买一台新电脑要花一大笔钱．take后面常跟双宾语，常见用法It takes sb．+时间+to do sth．做某事花了某人多少时间．例：It took them three years to build this road．他们用了三年时间修完了这条路．pay的基本用法是：（1）pay （sb．） money for sth．付钱（给某人）买…．例：I have to pay them 20 pounds for this room each month．我每个月要付20英磅的房租．（2）pay for sth．付…的钱．例：I have to pay for the book lost．我不得不赔丢失的书款．（3）pay for sb．替某人付钱．
