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．這里是說(shuō)過(guò)去的事情用一般過(guò)去時(shí)，主語(yǔ)是the brave child是人，表示花費(fèi)時(shí)間做某事用spend+時(shí)間或金錢(qián)+doing sth，spend的過(guò)去式是spent，兩小時(shí)two hours，救他的父母save his parents，獨(dú)自的by himself，直到用until引導(dǎo)時(shí)間狀語(yǔ)從句，主語(yǔ)是the firefighters，到達(dá)arrive，過(guò)去式arrived，故答案是spent two hours saving his parents by himself until the firefighters arrived．

點(diǎn)評(píng) spend，cost，take和pay的區(qū)別是歷年中考試題的必考內(nèi)容之一，雖然它們都可以表示"花費(fèi)"，但用法卻不盡相同．
spend的主語(yǔ)必須是人，常用于以下結(jié)構(gòu)：（1）spend time/money on sth．在…上花費(fèi)時(shí)間（金錢(qián)）．例：I spent two hours on this maths problem．這道數(shù)學(xué)題花了我兩個(gè)小時(shí)．（2）spend time/money （in） doing sth．花費(fèi)時(shí)間（金錢(qián)）做某事．例：They spent two years （in） building this bridge．造這座橋花了他們兩年時(shí)間．cost的主語(yǔ)是物或某種活動(dòng)，還可以表示"值"，常見(jiàn)用法sth．costs （sb．）+金錢(qián)，某物花了（某人）多少錢(qián)．例：A new computer costs a lot of money．買(mǎi)一臺(tái)新電腦要花一大筆錢(qián)．take后面常跟雙賓語(yǔ)，常見(jiàn)用法It takes sb．+時(shí)間+to do sth．做某事花了某人多少時(shí)間．例：It took them three years to build this road．他們用了三年時(shí)間修完了這條路．pay的基本用法是：（1）pay （sb．） money for sth．付錢(qián)（給某人）買(mǎi)…．例：I have to pay them 20 pounds for this room each month．我每個(gè)月要付20英磅的房租．（2）pay for sth．付…的錢(qián)．例：I have to pay for the book lost．我不得不賠丟失的書(shū)款．（3）pay for sb．替某人付錢(qián)．
