動(dòng)詞不定式作主語(yǔ)的用法 Grammar 動(dòng)詞不定式的基本形式為 to 動(dòng)詞原形 其否定形式是 not 動(dòng)詞原形 它能起名詞的作用 在句子中充當(dāng)主語(yǔ) 表語(yǔ) 賓語(yǔ)和賓語(yǔ)補(bǔ)足語(yǔ) 動(dòng)詞不定式在作主語(yǔ)時(shí) 常用it作形式主語(yǔ) 而往往將動(dòng)詞不定式放在謂語(yǔ)或表語(yǔ)之后 It snoteasytolearnaforeignlanguagewell Tolearnaforeignlanguagewellisnoteasy 學(xué)好一門(mén)外語(yǔ)不容易 在此句型中 如果要說(shuō)明動(dòng)詞不定式的動(dòng)作是誰(shuí)做的 可在不定式前加一個(gè)for引起的短語(yǔ) 作不定式的邏輯主語(yǔ) 即 Itis 形容詞 forsb todosth 對(duì)某人來(lái)說(shuō)做 是 如 It sdifficultforustofinishthework 對(duì)我們來(lái)說(shuō) 完成這項(xiàng)工作很困難 It shardformetoansweryourquestion 要我回答你的問(wèn)題很難 但是 如果表語(yǔ)是kind nice right wrong clever polite等描述行為者的性格 品質(zhì)的形容詞 則應(yīng)在不定式前加一個(gè)of引起的短語(yǔ) 即 Itis 形容詞 ofsb todosth 某人做 是 Itiskindofyoutohelpmewithmylessons 你幫助我做功課 太好了 Itissoniceofyoutocometoseeme 你來(lái)看我太好了 Ittakes took sb sometime todosth意為 做 花了某人多少時(shí)間 Ittakesheranhourtoreviewherlessonseveryday 她每天花一個(gè)小時(shí)復(fù)習(xí)功課 Ittookmorethan100 000slavestwentyyearstobuildtheGreatPyramid 十萬(wàn)多個(gè)奴隸花了20年的時(shí)間建成了那座大金字塔 Itis 名詞 todosth意為 做 是 Itisourdutytoservethepeople 為人民服務(wù)是我們的責(zé)任 Itisanhonourtomakeaspeechhere 在這兒演說(shuō)很榮幸 注意 動(dòng)詞不定式作主語(yǔ) 同時(shí)有一個(gè)不定式作表語(yǔ)時(shí) 不能轉(zhuǎn)換成 It s todosth 的句型 如 正 Toseeistobelieve 百聞不如一見(jiàn) 誤 It stobelievetosee Thisbeautifulbowlismadeof 金屬 2 Thestreetssoone whentherainbegan
