需改变时态的间接陈述句
间接引语里常要改变时态,这是因为原来讲的话与转述这些话之间有一段间隔。选择哪种恰当的形式取决于转述者的着眼点。在间接引语里通常并不确切地重复 讲话者说过的话。转述通常发生在过去,所以引述动词通常是过去时。因此,转述时从句的时态通常要“往回移”(back shift)。一条普遍的规则是:现在时变为过去时,过去时变为过去完成时。为过去时的情态助动词和过去完成时在转述时不变,因为不可能再往回移了。
使用间接引语主要是为了简洁、紧凑地把说话内容转述给第3者。请看下面直接引语变成间接引语时在时态等方面必须作出的相应变化:
(1)一般现在时改为一般过去时:
‘I'm thirsty,’she said.
“我渴了”她说。
She said (that) she was thirsty.
她说她渴了。
(2)现在进行时改为过去进行时:
‘I'm having a rest,’ she told them.
“我正在休息”她告诉他们。
She told them (that) she was having a rest.
她告诉他们说她当时正在休息。
(3)现在完成时改成过去完成时:
‘I've just made a new film,’ she told me.
“我刚完成一部新电影”她告诉我。
She told me(that) she had just made a new film.
她告诉我说她刚完成一部新影片。
(4)一般将来时改成过去将来时(一般用would +动词原形):
‘I'll have to ask my husband,’she said.
“我得问问我丈夫”她说。
She said (that) she would have to ask her husband.
她说她将得去问问她丈夫。
(5)情态动词由现在时改成过去时或条件时态:
‘I can see you tomorrow,’she said.
“我明天可以见你”她说。
She said (that) she could see me the next day.
她说她下一天可以见我。
‘I'll help you,’she said.
“我将帮助你”她说。
She said (that) she would help me.
她说她将帮助我。
‘I may return at six o'clock,’ she told me.
“我可能6点钟回来”她告诉我。
She told me (that) she might return at six o'clock.
她告诉我说她可能6点钟回来。
(6)为过去时或条件时态的情态助动词不变:
‘I could see you tomorrow,’she said.
“我明天可能会见你”她说。
She said (that) she could see me the next day.
她说她第2天会见我。
‘I would complain if I were you,’she told me.
“如果我是你的话,我会抱怨”她告诉我。

第1类条件句
如果我们认为将来的事件是可能发生的,就可用第1类条件句去描述将会发生什么事或不会发生什么事。其基本结构是:If + 一般现在时+将来时(或情态助动词),如:
If it rains tomorrow, we won't go to the seaside.
如果明天下雨,我们就不去海边。
if从句中的现在时表示需具备的条件,主句中的shall/will将来时表示可能的结果。具备的条件是真实的,可能真的下雨。
如果是这样,它就会有真实的结果。这就是为什么这样的陈述句常被称为“开放”条件句或“真实”条件句的原因。事实上,在第1类条件句中,一切现在时态都能用在if之后,而不仅仅是一般现在时。请看例句:
If he falls ,he'll hurt himself.
如果他摔倒了,他会伤着自己的。
If you don't hurry ,we'll miss the train.
你要是不赶紧点儿,我们就会误了火车。
If you feel better, you can get up.
你要是感觉好些了的话,你就能起床了。
If I am better tomorrow, I will get up.
如果我明天感觉好些了,我就起床下地。
If I have a headache, I will take an aspirin.
我要是头疼的话就会服用一片阿司匹林。
