很簡(jiǎn)單
我們說take part in -- - ,但如果有形容詞修飾part的時(shí)候,我們就要加一個(gè)a / an,如：take an active part in- ----又如：
1 Taiwan is part of China,但Taiwan is an indispensable part of China
2 This is part of my money for you.但：This is only a small part of my money for you.
( 明白了嗎?good day to you)語感告訴我，沒有這樣的用法。同樣的道理還有：have lunch, have a big lunch,He ate (a) half of the cake, He ate a big half of the cake.做個(gè)有心人，你就會(huì)學(xué)得更多。你我的語感應(yīng)該不是一個(gè)概念。我是做英語工作的。請(qǐng)問，你是什么職業(yè)？
