camellia现在进行时与一般将来时的转换

现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将
来的时间状语连用表示将要发生的动作。如：I am coming, Mum! 意为我就
来，妈妈！请看：
The train is leaving soon.
The train will leave soon.
3.宾语从句（3种）
宾语从句是英语复合句中的其中非常重要的从句之一。它是用一个句子 做另一个
句子的宾语，将这个句子叫做宾语从句。宾语从句做介词或及物动词的宾语。现
在从下 列三个方面总结归纳如下：
一，引导词
A,由that 引导的陈述句性的宾语从句，在很多动词如say, think, wi
sh , hope, see, believe, agree, expect, hear , feel等动词后。
连 词that只起连接作用，在从句中不做句子的成分，也无词汇意义，在口语中
常被省略，但在大多数情 况下还是以不省为好，特别是在笔语中。
例：I told him that he was wrong.
l在think, believe, suppose, expect等动词引起的宾语从句中，
有时谓语尽管是否定意义，却不用否定形式，而将think 等动词变为否定形式。
例：I don't think you are right. (我认为你做的不对)
l在许多带有复合宾语的句子中，that引导的宾语从句经常移到句子的后
面，而用it做形式宾语。
例：We think it wrong that he told a lie to everyone (我认
为他向每一个人撒谎是错误的)
B,由连词if、 whether 引导的表示是否...的宾语从句。Whether,
if 在从句中不做句子的成分，一般情况下，whether和if 可以替换。
例：I don't know if/whether he will come tomorrow.
The teacher asked if/whether we had finished the experi
ment.
l在介词后面的宾语从句中不用if引导
例：Everything depends on whether we have enough money。
l宾语从句中有or not时不用if引导.
例：I don't know whether the movie star will come or not.
l和不定式连用作宾语时不用if引导.
例：Whether to go there or not hasn't been decided.
C,由wh- 引导的宾语从句。连接代词who,whom,whose, what, which,
和连接副词when, where, why, how 等连接的宾语从句，它们在句中即有连
接从句的作用，又在句中充当句子的成分。
例：Do you know which film they are talking about? (which
做定语)
I don't know where he lives. (where 做地点状语)
二，宾语从句的语序，
宾语从句从句的语序必须是陈述语序，既连接词+主语+谓语+其他成分
例：I believe that they will come soon.
He asked me whether I was a teacher.
They wanted to know what they can do for us.
二，宾语从句的时态。
宾语从句的时态受主句的限制，
既：主句是一般现在时态，从句根据实际情况而定。
主句是一般过去时态，从句用相应的过去的时态。如果从句的动作发生在主
句之前，则从句要用过去完成 时态。 例: 1)She says that she is
a student.
She said that she was a student.
2)She says that she will fly to Japan in a week.
She said that she would fly to Japan in a week.
3)She says that she has finished her homework already.
She said that she had finished her homework already.
4)She says that she can sing a song in English.
She said that she could sing a song in English.
l如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一
般现在时态。
例：The teacher said that the earth goes round the sun.
He told me that Japan is an island country.
lCould you tell me...是用来征询对方的意见，语气委婉，并不表示
过去。
例：Could you tell me when we will visit the History Muse
um?
注意事项：
u由陈述句变成宾语从句时，要注意人称的变化。
例：She said:
She said that she had been to England before.
She asked me:
She asked me if I liked moths.
u宾语从句与简单句的交换。
