啡友L說動(dòng)詞promise的過去分詞跟著連詞（conjunction）用的as，成為as promised，常見用者——特別是在商業(yè)通信中。一家公司答應(yīng)寄送樣品給客戶，附函中說：We are sending you the sample, as （we） promised.會(huì)話中用以聲明會(huì)照辦事先說好的事情。例如你借了朋友一本書，久久未還。朋友偶然問起，你說明天一定奉還：I'll bring the book back tomorrow, as（I）promised，表示當(dāng)初說了要還，一定會(huì)還。
As加動(dòng)詞過去分詞，省略as之后的主語和動(dòng)詞be作為從句，是相當(dāng)簡(jiǎn)潔的表現(xiàn)方式，多見于新聞?dòng)⒄Z中。要注意的是如果時(shí)制和主句不同，be動(dòng)詞部分不能省略。例如論斯里蘭卡政局者說該國(guó)的權(quán)力曾經(jīng)多次證明不是通過勞動(dòng)階級(jí)所能取得：The way to power in Sri Lanka is not through the working class, as has been proved time and time again.主句中用現(xiàn)在時(shí)制，從句中非用現(xiàn)在完成時(shí)制不可，雖然略去了作為從句主語之it.再看：A spokesman said about ten targets were struck as planned.“一如原定計(jì)劃”，as planned足矣。
