1、第一讲主语 【语法讲解】主语的位置通常在句首，一般不省略。它是句子所要说明的人或事物，是谓语动词所表示动作的发出者。例如：1) The question is difficult.2) She is difficult to understand.3) 9483276105 is difficult to remember.4) To understand his words is difficult.5) Thinking in such a noise is difficult.6) That they will leave ahead of time is difficult.上述的六个
2、例句分别说明了主语的位置、特点及能够担当主语的成分。可以担当主语的有名词（例如1）、代词（例如2）、数词（例如3）、动词不定式（例如4）、动名词（例如5）和主语从句（例如6）。1名词表示人、事物、地点或抽象概念的名称:名词分类概念例子普通名词某一类人、事物、某种物质或抽象概念的名称书book，音乐music，朋友friend专有名词特定的某个人、地方或机构的名称玛丽Mary, 巴黎Paris, 联合国United Nations2代词是用来指代的词。能用来做主语的人称代词有单数复数我I 我们we你 you你们you他 he 她she它 it他们they3数词是表示“数量”和“顺序”的词。4动词
3、不定式为非谓语动词的一种形式，形式为动词不定式符号to加动词原形，即to do（do代表所有动词）。当动词不定式做主语时，往往放在谓语动词的后面，而用it做形式主语放在谓语动词的前面。例如上述例句4还可以改写为：It is difficult to understand his words.其中，it是形式主语，真正的主语是动词不定式to understand his words.5动名词为非谓语动词的另一种形式，形式为动词原形加词尾-ing构成，即doing （do代表所有动词）。某些结构中，也可以用it做形式主语放在句首，而将真正的主语（即动名词放到句尾）。例如It is no use a
4、sking her advice.6主语从句指的是在句子中做主语的名词从句。按英语的习惯，有些句子可以把it放在句首做形式主语，而将真正的主语主语从句放在句子的后面。例如It is well known to all of us that the moon moves round the earth.【特别提示】1） 祈使句的主语（you）经常省略；如：（You）Open the door, please. 2） 动名词，不定式和从句做主语时，谓语动词为单数。如上述例句中的4、5、6。【强化练习】判断下列各句的主语的位置及性质：21) Reading aloud is very importa

14、）小强从上课开始一直在说话。而英语的时态主要体现在动词的变化上。所有的动作和状态从时间上看，都可以分为现在、过去、将来和过去将来，其中现在时间里的四个时态是理解过去、将来和过去将来时间里的时态的关键。现在时（以动词do为例）形式主要用法一般现在时do (does)1.经常或反复发生的动作或存在的状态；2. 客观事实或普遍真理现在进行时amis doingare现在正在进行的动作现在完成时have donehas 1.过去开始并持续到现在；2.过去发生的动作但对现在仍留下某种后果和影响现在完成进行时have been doinghas 从过去某一时间开始一直延续到现在的动作（中间基本无停顿），并

17、nce 1991.9) Japan lies to the east of China.10) What are you doing?【练习解析】1) 一般现在时，主语为第三人称单数the sun，所以两个动词rise和set的词尾都加上了-s；2) 现在进行时，主语Mary是第三人称单数，所以be动词采用的是is；3) 现在完成时，主语my mother是第三人称单数，所以助动词have采用的是has；4) 现在完成进行时，主语为第一人称；5) 现在进行时，主语they是复数，所以be动词采用的是are；6) 一般现在时，主语my mother是第三人称单数，所以动词work的词尾加上了-s
18、；7) 现在完成进行时，主语she是第三人称单数，所以助动词have采用的是has；8) 现在完成时，主语为第一人称；9) 一般现在时，主语Japan是第三人称单数，所以动词lie的词尾加上了-s；10) 现在进行时，主语为第二人称。【巩固练习】（五）1. 判断下列各句的时态：1) We have been living here for 20 years already.2) He is reading outside.3) He has just come back.4) Light travels faster than sound.5) I have studied English s

44、同。第一句“我”是主语，谓语“打”这个动作是“我”发出的，所以第一句在语法上叫做“主动语态”；第二句“他”是主语，“他”是“打”这个动作的承受者，所以第二句在语法上叫做“被动语态”。与之相对应的英语译文是：1）I beat him.2) He was beaten by me.汉语里的被动语态是通过“被”字体现的，而英语中，被动语态是通过 “be+及物动词的过去分词”的这一形式体现出来的。以动词do为例，常用的被动语态的各种时态的形式如下：现在时过去时将来时过去将来时一般is (am, are) donewas (were) donewill (shall) be donewould (sho
45、uld) be done进行is (am, are) being donewas (were) being done_完成have (has) been donehad been done_【特别提醒】1） 被动语态中，助动词be有时态、人称和数的变化。2） 能够在被动语态中使用的动词必须是“及物动词”，因为只有及物动词才有宾语，才能将其宾语转换为被动语态句中的主语。3） 在被动语态句中，通常不用指出动作的执行者。如果有必要指出，则在句末用介词by代表动作执行者的名词或代词来表示。【强化练习】判断下列被动语态句的时态1) Cars are seen everywhere in cities.2) The work was finally finished.3) Mary will be invited to dinner tonight.4) The window has been broken.5) The classroom is being cleaned by the students.6) The house had been repaired before he came back.7) He said that no water would be broug
