Answer 1

【答案】

A

【解析】

試題分析：考查主謂一致。句意：當(dāng)庫(kù)克住在島上的時(shí)候沒(méi)有朋友怎樣生存對(duì)他來(lái)說(shuō)是最難的挑戰(zhàn)。排除B和D，是因?yàn)闊o(wú)論是動(dòng)詞不定式還是從句做主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞都用單數(shù)，，C不對(duì)是因?yàn)镃語(yǔ)序不對(duì)，因?yàn)閺木渥鲋髡Z(yǔ)時(shí)是陳述語(yǔ)序，所以A是動(dòng)詞不定式做主語(yǔ)謂語(yǔ)動(dòng)詞用單數(shù)，所以A正確。

考點(diǎn)：考查主謂一致。
