問：He leapt over the bar, outdoing what the last player had done（他躍過橫槓，表現勝於上一個選手）這一句，可不可改為Leaping over the bar, he outdid what the last player had done？
答：要說同時發生的兩個動作，可用「分詞子句（participle clause）＋主要子句（main clause）」句式：分詞子句即用ing或ed形式動詞的子句，主要子句所述則是作者認為較重要的事情，例如：He ran as fast as he could, trying to shake off his pursuers / Running as fast as he could, he tried to shake off his pursuers（他奮力逃跑，想擺脫追捕者）。讀者說的那一句，也是兩個寫法都可以。
不過，假如兩個動作有先後之分，則在先者應用分詞子句敍述，例如：Getting up, he stormed out of the room（他站起來，氣沖沖走出房間）。這一句不可改為He got up, storming out of the room。
問：讀報見到以下一句，句中called for的主詞（subject）是什麼？──He said notice was made later than required, which he thought called for improvement。
答：Which之後的he thought（他認為）二字，文法上可以略去，即which （he thought）called for improvement：called for的主詞是which，而which則是指句子上半截所說的事。全句意思是：「他說通告發出的時間，遲於規定，認為這一點有待改善。」
Which指句子前半截所述事情，是很常見的，例如：Leung has been taken to a mental hospital, which is good news（梁某人被送了去精神病院，那是好消息）。
