1、There goes the bell.铃响了。There comes the bus.汽车来了。Here she comes.她来了。注意：近几年，对一般现在时的考查常用过去时态或现在完成时态对考生进行干扰Months ago we sailed ten thousand miles across the open sea, which_ the Pacific,and we met no storm.A. was called B. is called C. had been called D. has been called虽然航海发生在过去，但是，海洋的名称不会因此而变化，所以要用一般

8、刻开始一直持续到现在（或今后还要继续一去）的动作;He has been doing the maths problems since 8:00.凡是不能用于现在进行时的动词均不能用于现成完成进行时。5.一般过去时表达特定的过去时间内发生的动作或存在的状况，或过去某一时间内经常发生或反复发生的动作或为; He often sang when he was a boy.He went to the cinema last night with her boy friend.用于I didnt know或I forgot，表示事先不知道或不记得，但现在已知道或记得的事情。用于I didnt kno

13、此可用一般过去时代替过去完成时。He （had） left before I arrived.8.一般将来时一般将来时有下列一些构成形式需要记住：will/shall do （侧重将来行为，不突出计划安排去做某事）be going to do （主观上打算或客观上可能发生）be doing （按计划将要发生，常和表示最近的将来时间连用）be about to do （按计划即将发生）一般将来时的用法：现在看来以后要发生的动作或存在的状态Tom will come next week.He will be here tomorrow.事物的固有属性或必然趋势Oil will float in w

18、 Ive spoken in public.III.被动语态的用法被动语态表示句子的主语是动作的承受者，也就是动作的对象，一般说来只有及物动词才有被动语态。其构成为be+及物动词的过去分词。助动词be有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。含有情态动词的谓语变化为被动语态时，由情态动词（can, may must, have to等）+be +动词的-ed形式。含有be going to , be to, used to, be about to等结构的复合谓语变为被动语态时，其构成为be going to （be to, used to, be about to）+
19、be +动词的-ed形式构成。1.被动语态的适用范围当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者时。这时不用by短语。This jacket is made of cotton. 这件上衣是棉料的。为了强调动作的承受者时Visitors are requested not to touch the exhibits. 要求参观者不可触摸展品。出于策略、委婉、礼貌等不提出动作的执行者You are said to be active recently. 据说你最近很活跃。常用于如下句型：s not known that 不得而知 Its said that 据说s report
20、ed that 据报道 Its not decided that尚未决定s believed that 据认为 Its announced that据宣布2.被动语态的句型常见句式是：主语（受动者）+be+过去分词+（by+施动者）He was scolded by the English teacher.主语+get+过去分词+其它成分The boy got drowned last summer./ She got fired because of her faults.使用这种结构不能带有“by+施动者”在现代英语中大量地出现了由get+及物动词的过去分词构成的被动语态，这就叫做get-
21、型被动语态。get-型被动语态中的过去分词数量有限，通常为单个的动词或比较简单的动词短语。get+及物动词的过去分词get常同marry, beat, break, damage, tear, strike, hurt, paint, invite, repair, dress, pay, wound等动词的-ed形式连用，构成被动语态。这种结构一般指动作的结果而非动作本身，常指最后终于，突然发生等意义。He got wounded in the battle. 他在战斗中受伤了。The boy got hurt on his way home from work. 男孩在回家的路上受伤了。g
22、et-型被动语态一般不宜用在含有双宾语的结构中，也不宜与see, hear, watch, listen to等感官动词构成被动语态。The old man was offered a large sum of money. （正）有人给了这位老人一大笔钱。The old man got offered a large sum of money. （ 误）get-型被动语态有时有言外之意或具有感情色彩He got taught a lesson. 他被教训了一顿。（有“活该”之意）How did the window get closed. 窗户怎么关上了?（有“不该关上之意）get-型被动语
23、态有时表示开始进入某种状态，而be+动词的-ed形式只表示存在的状态。She got tired. 她感到累了。（有开始感到疲劳的含义）She was tired. （只表示”她累了”）带有双宾语（直接宾语和间接宾语）的主动句变为动句，其主语可以是直接宾语，也可以是间接宾语。She lent me a bike.被动：I was lent a bike（by her）.A bike was lent to me（by her）.情态动词+be+过去分词This problem must be worked out in half an hour.双重被动式：主语+被动式谓语+不定式的被动式+其
24、它成分These magazines are not allowed to be taken out of the reading-room.The murderer was ordered to be shot.3.主动表示被动的几种情况不及物动词与状语连用，用以表示主语的品质和状态常见动词是：cut,sell,read,write,fill,cook,lock,wash,drive,keep等This knife cuts well.这把刀好切。These books sell well.这些书好卖。The pen writes smoothly.这支笔写起来流畅。Meat wont ke
25、ep long in such hot weather.肉在这样热的天气里放不长久。The cloth washes well.这种布好洗。一些连系动词的主动式+形容词。常见动look,smell,taste,sound,feel,prove,turn out等The apples taste good.The flower smells wonderful.The news proved/turned out trueCotton feels soft.4.不可变为被动语态的几种情况当句子的宾语是反身代词时（因为反身代词不可作主语）He can dress himself. 他能自己穿衣服。
26、不可变为Himself can be dressed by him.当句子的宾语是相互代词时（因为相互代词不可作主语）We help each other/one another.不可变为Each other/One another is helped by us.动宾结构的固定短语只能用于主动式，不能用被动式He lost heart.不可变为Heart was lost by him.类似lose heart词组的还有make a face,keep silence,keep words,lose in thought等等take part in,belong to ,own,have,h
27、ate,fail,contain等表状态动词没有被动语态She took part in the sports meet.不能变为The sports meet was taken part in by her.当have, cost, fit, last, hold等表示状态的及物动词作谓语时Our village has twenty tractors. 我们村有20台拖拉机。The hall can hold 2000 people. 这个大厅能盛2000人 The war lasted four years. 这场战争持续了4年 当某些及物动词（如leave, enter, join,等）的宾语是表示处
