6、n I havent read it yet. 我还没有读过这个。 n Have you ever seen each other before?你们 见过面吗？ nB.表示过去已经开始、持续到现在（也许还会继 续进行下去）动作或状态，常和表示一段时间状 语，如:today, these days, since,for,this month, now等连用。 n例如:I have studied English for two years. 我学英语已经两年了。 They have lived in Beijing since 1980. 他们自年就一直住在北京。 Weve known eac

8、e back for two years.（误） 终止性动词完成时的否定式表示一种否定状态是可以延续的， 所以其否定式可以和段时间状语连用。 n如：I havent seen him for ages.我好久没见到他了。（ 现在仍没见到他） 1. 现在完成时表示过去发生或已经完成的某一动作对现在 造成的影响或结果。(汉语中常用“已经”、“过”、“了”等 表达）通常与表示包括现在在内的时间副词 just， already, before, yet, never, ever 等状语连用。例如： I have never heard of that before.

10、：句中谓语动词要用延续性动词） 一段时间的表达方法有两种: for +一段时间 for a year for two weeks for three years 过去的某一时刻, since nine since last week 一般过去时态的时间状语从句 since you came since you got home 注意:for 和since 所引导的时间状语都表示一段时间。 He has been away since last week.

12、较 n1）一般过去时表示过去某时发生的动作或单纯叙述过 去的事情，强调动作，和现在不发生关系。而现在完成 时表示过去发生的某一动作对现在造成的影响或结果， 强调的是现在的情况。 n 2）一般过去时常与具体的时间状语连用，而现在完 成时通常与模糊的时间状语连用，或无时间状语。 n 一般过去时的时间状语有：yesterday，last week ，ago，in1980，in October，just now等具体的时 间状语。 n 共同的时间状语有：this morning，tonight，this summer，before，already等。 n 现在完成时的时间状语有：for，since，e

13、ver， never，just，already，yet，in past years等不确定 的时间状语。 请大家认真分析比较下列各例句：请大家认真分析比较下列各例句： n I saw this film yesterday. n（只说明动作发生在过去。） n I have seen this film. n（强调对现在的影响，电影的内容已经知道了。） n She has returned from Paris. n（她已从巴黎回来了。） n She returned yesterday. n（她是昨天回来的。） n He has been in the League for three yea

14、rs. n（在团内的状态可延续。） n He joined the League three years ago. n （ 三年前入团，joined为短暂行为。） n注意：句子中如有一般过去时的时间副词（如 yesterday, last week, in 1960）时，不能使用现在完成时，要用过去时。例如 ： n（错）Tom has written a letter to his parents last night. n（对）Tom wrote a letter to his parents last night. 瞬间动词可以用于现在完成时，但不能和表 示一段时间的状语连用。如可说“He

15、 has left.”但不 能说“He has left for three years.” 如果要表达“他 已走了三年了”可用以下几种表达法： 一、用ago, 使用一般过去时。 He left here three years ago. 二、用“It is +一段时间since 一般过去时从句 ” It is three years since he left here. 三、用“ 一段时间have/ has passed + since + 一 般过去时从句” Three years have passed since he left here. 以上三种表示方法适用于所有瞬间动词。 另外

16、，还可用其它表示方法，但只适用于部分 瞬间动词。具体办法是将瞬间动词转化为表延续的 动词或者表状态的be+名词形容词或副词介词 短语等。 1.直接转化成延续性动词 buy catch (get) a cold borrow come/go /become have have a cold keepbe 2.转换成be+名词 join the army join the Party go to school be a soldier be a Party member be a student 3转换成be+形容词或副词 die finish begin leave fall sleep clo

I visited the factory last year. 二看句首有无疑问词。

20、如果笼统地问人家做过某事 了吗（句首无疑问词），常用现在完成时；但进一 步询问何时、何地、何原因、用什么方式做那事时 （句首有疑问词）就要用一般过去时。如： Have you had your breakfast? Yes, I have. When did you have it? At seven thirty. 三看句中谓语动词是否为延续性动词。如果表示的动作或 状态一直延续到现在，最好选用延续性动词，并使用现在 完成时；如果是瞬间动词，则用一般过去时。如： He has been a league member for two months. He joined the Youth L

30、, both, half 等）的用法一样，不仅要放在所有形容词的前面，而且要放在 中位限定词（如冠词、指示代词、物主代词等）和后位限定词（序数词、基数词等）之前。 如：He got double the sum. 他得到了那个金额的两倍。 They want at least double their salaries. 他们想至少要把工资提高一倍。 Everything was almost double the normal price. 样样东西几乎都是平时价格的两倍。 有时可放在 what 从句之前。 如：His income is double what it was five ye

31、ars ago. 他的收入是 5 年前的两倍。 二、用作形容词的用法 double 用作形容词时，它有多个意思： 1. 表示“两倍的” “加倍的” 。 如：a double helping 一客双份的食物 2. 表示“双的” “成双的” “双层的” 。 如：You mustnt park on double yellow lines in England. 在英国双黄线上不许停车。 The room has double doors. 这房间有双层门。 3. 表示“两人用的” “双人的” 。 如：We bought a double bed. 我们买了一张双人床。 4. 表示“（意义、标准等）

32、双重的” 。 如：The word has a double meaning. 这个词有双重意思。 This switch has a double purpose. 这个开关有双重用途。 注意：用作形容词的 double 与用作限定词时的 double 不仅意思不一样，而且词序也不一 样：按照现代英语语法，形容词总是放在限定词之后，所以用作形容词的 double 总是放在 冠词、物主代词、指示代词等限定词之后。比较： Do you like the double bed? 你喜欢这张双人床吗？ We cannot pay double the amount. 我们不能付双倍的数目。 三、用作

33、副词的用法 double 用作副词时，有两个意思：一是表示“两人一道地” ，二是表示“双倍地” 。 如：The two children sleep double. 这两个小孩合睡一床。 The price of many things increased double. 许多东西的价格都上涨了一倍。 注意，用作副词的 double 主要用来修饰动词；若用于修饰形容词，则通常用 doubly 这一 副词形式。 如：Youve got to be doubly careful when youre driving in fog. 雾天开车你得加倍小心。 Losing both the Cup a

34、nd the League is doubly disappointing. 在杯赛和联赛中双双失败真是令 人失望透顶。 四、用作名词的用法 double 用作名词，意思比较多，表示“两倍（的数或量） ” “加倍之物” “酷似的人或物” “双打”等。 如：Ill have a double, please. 请给我来一杯双份的。 Two doubles were employed for this scene. 拍这个场面雇用了两个替身。 五、用作动词时的用法 double 用作动词时，可及物或不及物，意思是“（使）加倍” “对折” 。 如：The music doubled in volum

35、e. 音乐的声音加大了一倍。 He told me not to double the pages. 他叫我不要折书页 b. 句式包： She helped you to work out the answers yourself no matter how difficult they were. 她帮助你自己算出答案，无论它们有多难。 no matter 常与疑问代词或疑问副词一起构成连词词组引导让步状语从句，意为“不管， 无论” ，在运用时应注意以下几点： 一、注意从句的时态 由 no matter what/who/where/when，引导的从句往往用一般现在时或一般过去时。如：No

36、 matter who you are, you must obey the rules. 无论你是谁，都应该遵守规则。 二、注意被修饰的名词、形容词以及副词的位置 no matter what/whose/which 修饰名词时，该名词必须紧跟其后；no matter how 修饰形容词 或副词时，该形容词或副词也必须紧跟其后。 如：No matter how hard he works, he find it difficult to make ends meet. 无论他多么努力工作， 却总是入不敷出。 三、注意“no matter+疑问词”结构与“疑问词+ever”在用法上的区别 1.

37、 “no matter+疑问词”结构只能引导让步状语从句，这时可以和“疑问词+ever”互换。 如：No matter where he may be（=Wherever he may be）, he will be happy. 他无论在什么地 方都快乐。 2. 而“疑问词+ever”还可以引导名词性从句。 如：Give this book to whoever likes it. 谁喜欢这本书就给谁吧。 （这里不能用 no matter who） 3. whoever 既可引导名词性从句，又有在从句中作主语、宾语、表语等；whomever 也可引 导名词性从句，但只能在从句中作宾语。 如：You may invite whomever you like. 4. whatever 表示“无论什么” ，没有一定的范围限制； whichever 表示“无论哪一个、无论哪些” ，其后可接一个名词。 如：Eat whichever cake you like.
