4.瞬间动态系动词能否与时间段连用的问题
英语中某些表示瞬间意义的系动词不能与“for+时间段,since+时间点,how long until+时间,by + 时间,so far”等直接连用。例如:
①不能说:He has become a teacher for 2 years.
应改为:He has been a teacher for 2 years.
②不能说:He has turned writer since 3 years ago.
应改为:He has been a writer since 3 years ago.
或It is three years since he turned writer.
③不能说:He got angry until his child came back home.
应改为:He didn’t get angry until his child came back home.

5.系动词能接几种表语(从句)
系动词除了接adj.\n.\prep.短语,某些adv.以外,还可接以下几种表语形式:
①能接as if/as though表语从句的系动词有:look(看起来),smell(闻起来),sound(听起来),feel(觉得);appear(显得),seem(似乎)。例如:
It looks as if we are going to have snow.看样子天要下雪了。
He looked as if he had just stepped out of my book of fairy tales.
他看来好像刚从我的童话故事中走出来似的。
She seemed as if (though) she couldn’t understand why Laura was there.
看来她好像不能理解为什么劳拉呆在那儿。
It sounds to me as though there’s a tap running somewhere.
我好像听到某处水龙头流水的声音。
She felt as if her head were splitting.
她仿佛觉得她的头要裂开了。
The river appeared as if enveloped in smog.
那条河好像笼罩在烟雾之中。
It seems as if it were spring already.
好像已是春天了。
②可用于“It+系动词+that从句”结构的有:seem, appear, 不可用be, look。如:
It seemed that he had made some serious mistakes in his work.
好像他在工作中犯了严重错误。
It appeared that he was talking to himself.
好像他在自言自语。
③能用不定式作表语的系动词有:be, seem, get, look, appear, prove, grow.
Her job is to look after the children.
她的工作是照料孩子们。
He seems not to look after the children.
他好像不是她的父亲。
She looks to be a young girl of twenty year-old.
她看起来像是一个20岁的年轻姑娘。
He didn’t appear to dislike it.
看不出他憎恨此事。
My advice proved to be wrong.
我的建议证明是错误的。
He will grow to like this work gradually.
他会逐渐喜欢这个工作的。
④能与there连用的系动词有:be, appear, seem.
There appeared to be only one room.
那儿好像只有一个房间。
There seems(to be)no need to go.
似乎没有必要走。

6.能用两种否定形式的系动词有两个:seem, appear.
举例说明:
It doesn’t seem that we can get our money back.= It seems that we can’t get our money back.
He seems not to be her father.= He doesn’t seem to be her father.
The baby doesn’t appear to be awake.= The baby appears not to be awake.

7.后接作表语的过去分词可构成系表结构
能构成系表结构的系动词通常有两个:第一个是常见的be(is, am, was等);第二个是get,口语中常用。
当二者作系动词用时,它们均表示一种存在状态,而不表示被动动作;当二者作助动词用时,后接作谓语的过去分词构成被动语态。
Be + P.P常可以用get + P.P.来代替,但是并不是be系动词总是可以用get来代替。Get + P.P.系表结构常用于以下两种情况:
1)表示偶然的、突发性的、意想不到的被动动作的结果或状态。
Last night I got caught in the downpour.昨夜我被雨淋了(表示意想不到)
The new car got scratched.新车给刮坏了。(表突发性)
2)表示对自身所作的事。如get dressed, get lost等。
John got injured while playing football last Saturday.约翰上周星期六踢足球时受了伤。
They got married last month.他们上个月结婚了。
另外,要注意区分系表结构与被动语态结构的用法。

考点名称:不定式

  • 动词不定式:
    指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。
    动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。

  • 动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
    动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
    这一使动者我们称之为逻辑主语,其形式如下:
    时态 主动形式  被动形式 
    一般式 (not) to do (not) to be done
    完成式 (not) to have done (not) to have been done
    进行式 (not) to be doing  
    完成进行式 (not) to have been doing  

  • 不定式的用法:
    1、不定式作主语
    例如:To remember this is very important.
    注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。
    例如:It is very important to remember this.
    2、不定式作表语
    例如:He seems to be ill.
    注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be),
    二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形,
    三是表示想法、约定、义务、命令、可能性、命运等,如: 
    You are to come when I call.
    3、不定式作宾语
    例如:I can not afford to buy a car.
    注意:
    ①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。
    例如:I had no choice but to wait.
    ②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后
    例如:I find it difficult to learn Japanese well.
    4、不定式作宾语补足语
    例如:Who taught you to drive?
    5、不定式作定语
    例如:I have a question to ask you.
    注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth.
    如:It is the best way to do (of doing) it.
    但是以下名词后接不定式作定语时通常不能换成of doing sth.
    attempt  courage  decision  effort  fortune  failure  invitation  wish
    6、不定式作状语
    例如:I went to France to learn French.

考点名称:一般现在时

  • 一般现在时:
    :表示通常性、规律性、习惯性的状态或者动作(有时间规律发生的事件)的一种时间状态。

  • 一般现在时的具体用法:
    1. 表示经常的或习惯性的动作,常与表示频率的时间状语连用。    
    e.g.  I leave home for school at 7:00 every morning. 
    2. 表示客观事实和普遍真理。    
    e.g.  The earth moves around the sun.
    3. 表示现在发生的具体动作或存在的状态 
    e.g. He lives in Beijing now.
    4. 习惯性的爱好或行为
    e.g. I like dancing while she likes singing.
    5. 表示预先计划或安排好的行为。 
    e.g.  Our class begins at 7:45.
    6. 在时间状语从句和条件状语从句中,常用一般现在时代替将来时。 
    e.g.  If you come, we will wait for you.
    7. 表示格言或警句中。 
    e.g.  Pride goes before a fall. 骄者必败。 
    8.表示主语具备的性格、能力、特征和状态。 
    e.g. I don't want so much. 
    Ann Wang writes good English but does not speak well.
    比较:Now I put the sugar in the cup. 
      I am doing my homework now.
    9.在时间状语从句和条件状语从句中,常用一般现在时代替将来时。 
    10.小说故事用一般现在时代替一般过去时。新闻报道类的内容,为了体现其“新鲜”性,也用一般现在时来表示过去发生的事情。 
    11.有些表示状态和感觉的动词表示现在发生的具体行为时,只用一般现在时,而不用进行时态。 
    注意★:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。 
    例:Columbus proved that the earth is round.. 第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me,I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。
