你要在此地停留多久?(3) fall into “落入,陷入”如:he was drunk and fell into the water.他酒醉跌落水中.三、語法知識(shí)1. 被動(dòng)語態(tài)謂語動(dòng)詞的語態(tài)表示句子的主語和謂語動(dòng)作之間的關(guān)系： 1）當(dāng)句子的主語是謂語動(dòng)作的執(zhí)行者時(shí)，主、謂之間的關(guān)系稱為主動(dòng)語態(tài)； 2）當(dāng)句子的主語是謂語動(dòng)作的承受者時(shí)，主、謂之間的關(guān)系稱為被動(dòng)語態(tài)。 例如： i teach english.（主動(dòng)語態(tài)）我教英語。 our english is taught by him.（被動(dòng)語態(tài)）我們的英語是由他教的。 he speaks english.（主動(dòng)語態(tài)）他說英文。 english is spoken in many countries all over the world.（被動(dòng)語態(tài)）世界許多國家都講英語。 在被動(dòng)語態(tài)的句子中，謂語部分的結(jié)構(gòu)是be + p.p.（過去分詞）。被動(dòng)語態(tài)的句子有時(shí)態(tài)的變化，這個(gè)變化反映在be動(dòng)詞上。也就是說，把一個(gè)句子做成被動(dòng)語態(tài)的句子，只需要寫出be動(dòng)詞的所需時(shí)態(tài)，再加上所給動(dòng)詞的過去分詞就行了。當(dāng)然，這只是指謂語部分而言。我們知道，be動(dòng)詞作為一個(gè)獨(dú)立的謂語動(dòng)詞有自己現(xiàn)在分詞（being）和過去分詞 （been）。那么，下面我們來看看be在各種時(shí)態(tài)中的變化形式：一般現(xiàn)在時(shí) am / is / are 一般過去時(shí) was / were 一般將來時(shí) shall / will + be 過去將來時(shí) would / should + be 現(xiàn)在進(jìn)行時(shí) am / is / are + being 過去進(jìn)行時(shí) was / were + being 現(xiàn)在完成時(shí) have / has + been 過去完成時(shí) had + been 說明：1）以上的八個(gè)時(shí)態(tài)可用于被動(dòng)式，其它沒有列舉的時(shí)態(tài)都不宜用于被動(dòng)語態(tài)的句子中。2）另外，表中被斜線隔開的詞表示，供根據(jù)具體情況作選擇。弄清楚了be在各種時(shí)態(tài)中的變化形式以后，我們就能很輕松地寫出被動(dòng)語態(tài)的各種時(shí)態(tài)了。 我們可看看下面的實(shí)例： english is spoken in many countries all over the world .（一般現(xiàn)在時(shí)） 世界上許多國家都講英文。 some tv sets for sale in the department store were stolen last night. （一般過去時(shí)） 那家商場(chǎng)用來出售的部分電視機(jī)昨晚被盜。 he wont be allowed, by his father, to marry mary. （一般將來時(shí)） 他父親不會(huì)讓他娶瑪麗為妻的。 they would be sent to the army when they finished the training. （過去將來時(shí)） 他們結(jié)
