一般情況下賓語從句的時態(tài)必須和主句的時態(tài)保持一致: 一、如果主句的謂語動詞是一般現(xiàn)在時或一般將來時,,賓語從句中的謂語動詞可根據(jù)意義的需要,,使用任何一種時態(tài)。如: 1) Could you tell me when you will come again? 你能告訴我你什么時候再來嗎,? 2) I don't know if he arrived yesterday. 我不知道他是否昨天到了,。 3) Could you tell me what you were doing at eight last night? 你能告訴我你昨晚八點在干什么? 二,、如果主句的謂語動詞為一般過去時,,從句應用相應的過去時態(tài)。 1. 如果主句中的謂語動詞所表示的動作與從句的動作同時發(fā)生,,則從句應用過去進行時或一般過去時,。如: 1) She said that she was working on the Internet. 她說她在上網(wǎng)。 2) He told me that he knew the computer technology very well. 他對我說他精通電腦技術(shù),。 2. 如果從句的動作發(fā)生在主句的動作之前,,則從句應用過去完成時,。如: 1) He didn't know what they had come here for. 他不知道他們到這里來的目的。 3. 如果從句的動作發(fā)生在主句的動作之后,,則從句應用過去將來時,。如: 1) Jim told me he would spend his holidays in the south. 吉姆告訴我他將到南方度假。 使用賓語從句的時態(tài)還應注意下列特殊情況: 一,、如果賓語從句中有明確表示過去的時間狀語,,不論主句用什么時態(tài),從句一律用過去時,。如: 1) She said she came to work here in 1998. 她說她是1998年來這里工作的,。 2) The teacher told us that the war broke out in the winter of 1923. 老師告訴我們那場戰(zhàn)爭爆發(fā)于1923年的冬天。 二,、如果賓語從句表示客觀真理,、科學原理、自然現(xiàn)象,、現(xiàn)階段存在的客觀事實,、現(xiàn)在經(jīng)常性或習慣性的動作、諺語,、格言等,,不論主句用何種時態(tài),從句一律用一般現(xiàn)在時,。如: 1) Our teacher told us that light travels much faster than sound. 我們老師對我們說光比聲音傳播要快得多,。 2) The mother told his son that two and three is five. 母親告訴孩子二加三等于五。 3) We all knew that a friend in need is a friend indeed. 我們都知道,,患難之交才是真朋友,。 4) He told me that his father is an English teacher. 他告訴我他父親是名英語老師。 |
