考查名詞單復(fù)數(shù)。前有oneof修飾，故用名詞的復(fù)數(shù)形式。2.when

考查連詞。前面的intheearly19thcentury是時(shí)間狀語(yǔ)，根據(jù)句意，設(shè)空處表示“當(dāng)……的時(shí)候”，引導(dǎo)時(shí)間狀語(yǔ)從句，故填when。3.frustrated

考查詞性轉(zhuǎn)換。在系動(dòng)詞became后接形容詞作表語(yǔ)，故填frustrated。4.for

考查介詞。因onceandforall為固定搭配，意為“最終地；徹底地”。5.toblame

考查非謂語(yǔ)動(dòng)詞。此處toblame用不定式的主動(dòng)形式表被動(dòng)。6.a

考查冠詞。因asaresult是固定搭配，表示“因此”。7.carried

考查動(dòng)詞的時(shí)態(tài)。根據(jù)上下文謂語(yǔ)動(dòng)詞的時(shí)態(tài)可知，用一般過(guò)去時(shí)，故填carried。8.removed

考查非謂語(yǔ)動(dòng)詞。句中已有謂語(yǔ)had，故remove應(yīng)作為非謂語(yǔ)動(dòng)詞；又因thehandleofthepump與remove之間是被動(dòng)關(guān)系，故用過(guò)去分詞形式。9.Fortunately

考查詞性轉(zhuǎn)換。修飾整個(gè)句子，用副詞作狀語(yǔ)，故填Fortunately。10.isconsidered
