選B如果是過(guò)去進(jìn)行時(shí),不應(yīng)該是going speaking,應(yīng)該是speaking.答案中沒(méi)有,只能是過(guò)去將來(lái)時(shí).The teacher was just going to speak when the bell rang.鈴都響了,可是老師還打算繼續(xù)講下去.be going to do sth打算做...going speaking用在哪里？我覺(jué)得這句話也對(duì)，go doing sth，例如go hiking等等。一般go doing sth表示去做某事。比如：go hiking 去遠(yuǎn)足，go shopping 去購(gòu)物，這些都為固定搭配。沒(méi)有g(shù)o speaking 的說(shuō)法，你總不能說(shuō)“去說(shuō)”吧，因?yàn)間o有“去”的基本意思，所以用在該題中不合適。最合適的就是B在過(guò)去的那個(gè)時(shí)間里，老師打算繼續(xù)講下去。過(guò)去將來(lái)時(shí)was/were going to do sth
