在英语中,名词性从句可以替代名词,作为主语、宾语或补语。将句子改为主语从句时,需在句首加上“that”或“whether/if”,并将动词改为不定式;将句子改为宾语从句时,需在句中引入连接词;将句子改为表语从句时,需在主语后加连接词。注意连接词的使用和句子的语法结构。
句子改成主语从句时,需要在句子前加上“that”或“whether/if”,并将动词改成不定式形式。
例如,原句为:“He will come tomorrow.” 可以改写成主语从句:“That he will come tomorrow is certain.”
句子改成宾语从句时,需要在句子中引入一个连接词,如“that, whether/if, who, whom, whose, which, when, where, how, why”等。
例如,原句为:“I know he is coming tomorrow.” 可以改写成宾语从句:“I know that he is coming tomorrow.”
句子改成表语从句时,需要在主语后面加上一个连接词,如“that, whether/if”。
例如,原句为:“His answer was yes.” 可以改写成表语从句:“His answer was that he agreed.”
