中考英語動(dòng)詞不定式重點(diǎn)

1、動(dòng)詞不定式是初中英語的語法重點(diǎn)之一,也是每年中考英語試題的考點(diǎn)之一。它是動(dòng)詞的一種非謂語形式,沒有人稱和數(shù)的變化,不能單獨(dú)作句子的謂語。其構(gòu)成形式為"to+動(dòng)詞原形",to 為動(dòng)詞不定式的符號(hào),本身無意義。動(dòng)詞不定式具有兩大特點(diǎn):1.具有動(dòng)詞的特點(diǎn),因此,后面可以跟表語、賓語或狀語,構(gòu)成動(dòng)詞不定式短語。2.具有名詞、形容詞或副詞的特點(diǎn),可以在句子中用作主語、賓語、賓語補(bǔ)足語、狀語、定語、表語及同位語等。下面以近幾年全國(guó)部分省市的中考英語試題為例,對(duì)不定式的難點(diǎn)以及它在中考英語中的考查點(diǎn),作一簡(jiǎn)要的總結(jié)和分析,供同學(xué)們學(xué)習(xí)時(shí)參考。一、動(dòng)詞不定式作主語1.
