that, which, who, whom 功能類似的代名詞, 因?yàn)榫o跟名詞本身, 幾乎多余, 所以隨時(shí)都可省略而不影響原意

語(yǔ)法書背多了, 看不到 that, which, who 就覺(jué)得怪, 但代名詞過(guò)多會(huì)造成無(wú)謂的重復(fù), 應(yīng)盡量避免

日常英語(yǔ)會(huì)話中常聽(tīng)到    "I think that..[停頓, 然后一整句]"     說(shuō)出 that 讓對(duì)方先別出聲, 讓我先好好想想

還有日常會(huì)話(尤其是辯論) 或廣告中常見(jiàn)的   "... Which is why..."   W 大寫, Which = 代名詞, 緊跟剛說(shuō), 剛寫的復(fù)雜內(nèi)容, 而不重復(fù)     語(yǔ)法書不允許, 但很常見(jiàn)
