1 现在完成时中 “since ”和“ for ”的区别 1) since + 过去一个时间点 (如具体的年、 月、日期、 钟点、 1980 , last month , half past six )。 I have been here since 1989. 2) since + 一段时间 + ago I have been here since five months ago. 3) since + 从句 Great changes have taken place since you left. Considerable time has elapsed since we have been here. 4) It is + 一段时间 + since 从句 It is two years since I became a postgraduate student. Since 用来说明动作起始时间, for 用来说明动作延续时间长度。 I have lived here for more than twenty years. I have lived here since I was born.. My aunt has worked in a clinic since 1949. Some new oilfields have been opened up since 1976. I have known Xiao Li since she was a little girl. My brother has been in the Youth League for two years. I have not heard from my uncle for a long time. 注意:并非有 for 作为时间状语的句子都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for many years. (现在我仍在这里工作。) 小窍门:当现在完成时 +一段时间,这一结构中,我们用下面的公式转化,很容易就能 排除非延续动词在完成时中的误使。 1) (对) Tom has studied Russian for three years. = Tom began to study Russian three years ago , and is still studying it now. 2) (错) Harry has got married for six years. = Harry began to get married six years ago , and is still getting married now. 显然,第二句不对, 它应改为 Harry got married six years ago. 或 Harry has been married for six years. 声音: sound, noise 与 voice 的区别 sound 表示听起来像⋯⋯和 like 连用,如: It`s sounds like a bird. 听起来像鸟在叫。 voice 表示嗓音,说他的嗓音很动听,用 his voice was good. noise 是杂音,响动的意思。如:我听到有动静。 I heard a noise . 这是一组与 “声音 ”有关的名词,在使用上有区别。 sound 泛指 自然界各种各样的声音 ,不论其高低、是否悦耳等。 如: I heard the sound of running water. 我听见流水声。 Light travels faster than sound. 光比声音传播得快。 2 noise 表示 “噪音、喧闹 ”,指的是人们不愿听到的声音或嘈杂声。它可以作可数名词, 也可以用作不可数名词。如: I heard some strange noises last night. 昨夜我听见一些奇怪的响声。 There's a lot of noise here. 这个地方人声嘈杂。 voice 用于人时,指说话、歌唱或发笑的声音,也可指发言权。用于其它方面时,常含 悦耳之声,如鸟鸣声,乐器声音等。如: Please speak in a louder voice. 请大声说。 说: tell , speak, say,talk 的区别 tell 意为 “告诉、 讲述 ”,指某人把某一件事、 一条信息传送给别人或讲述一件事。 tell sb sth 意为 “告知某人某事 ”。 tell sb to do sth 意为 “告诉某人去做某事 ”。 speak 意为 “说话、 讲话 ”,后面主要接语言。 speak to 意为 “和 .....讲话、 谈话 ”。 speak of 意为 “提到、说起 ”。 speak to sb about sth talk 意为 “谈话、讲话 ”,如果只有一方对另一方说话时,一般用 talk to ;如果双方或多 方交谈,多用 with 。 talk about 意为 “谈论 ...... ”。 have a talk with 意为 “与 ...... 交谈 ”。 say 意为 “说” 。 say sth to sb 意为 “对 ...... 说 ”。 It is said that... 意为 “据说 ”。 首先是 say: 之后要有说的内容,如 He said nothing. ▲ say 一般作及物动词用,着重说话的内容,它的宾语可以是名词,代词或宾语从句。 eg: He can say his name. 他会说他的名字。 Please say it in English. 请用英语用。 She`s saying , Don`t draw on the wall. 她在说 “别在墙上画 ”。 ▲ speak 强调说的动作,不强调所说的内容 。作及物动词时,常以某种语言作宾语。 作不及物动词时,常见的搭配形式有: speak of something/somebody 谈到某事(某人) speak to sb 跟某 人讲话,此外 speak 还可用于在较为正式的场合了表演讲或演说。 Can you speak Japanese? 你会说日语吗? She is speaking to her teacher. 她正在跟她的老师说话。 He spoke at the meeting yesterday. 他昨天在会上讲了话。 ▲ talk 一般为不及物动词,意思是 “交谈,谈话,着重强调两具之间的相互说话。 eg: She is talking with Lucy in English. 她正在和露茜用英语交谈。 What are you talking about? 你们在谈论什么? The teacher is talking to him. 老师正在和他谈话。 ▲ tell 常作及物动词,意为 “讲述,告诉,动词常跟双宾语。 tell sb sth = tell sth to sb 告诉某人某事。 eg: He is telling the children a story. 他正在给孩子们讲一个故事。 Did you tell her the news? = Did you tell the news to her? 你把这个消息告诉她了吗? used to 与 be used to ( 1) used to + do : "过去常常 "表示过去习惯性的动作或状态,但如今已不存在。 Mother used not to be so forgetful. Scarf used to take a walk. (过去常常散步) 3 ( 2) be used to + doing : 对 ⋯⋯ 已感到习惯,或 " 习惯于 ", to 是介词,后需加名词或动名 词。 He is used to a vegetarian diet. Scarf is used to taking a walk. (现在习惯于散步) 将要: be to 和 be going to be to 表示客观安排或受人指示而做某事。 be going to 表示主观的打算或计划。 I am to play football tomorrow afternoon. (客观安排) I'm going to play football tomorrow afternoon. (主观安排) twice 、 two times 关于 A runs twice faster than B 这个的翻译,现在都还存在争议。有的人认为是 A 的速 度是 B 的 2 倍,有人认为是 A 比 B 快 2 倍 =A 是 B 的 3 倍。 “ A + be + 倍 数 + as + 计量形容词原级 + as + B ”。表示 A 是 B 的 N 倍。 1.This tree is three times as tall as that one. 这棵树是那棵树的三倍高。 2.His father is twice as old as he. 他父亲的年纪有他两倍大。 两倍用 twice ,不用 two times. 注意: 两倍一般都用 twice , 不用 two times 例如: This tree is twice higher than that one. =This tree is twice as high as that one. =This tree is twice the height of that one. 倍数 +比较级 + than ...= 倍数 + as + 形容词原形 +as ...= 倍数 +the + 形容词所对应的名 词 + of ... other 、 another 、 others、 the other ( 1) other 后既可接可数名词复数形式又可接不可数名词,如:可数, other pencils 其 它的铅笔, other students 其他的学生。 不可数 other tea 别的 /其它的茶, other information 别 的 / 其它消息。 any other 其他一切的什么 ⋯⋯ ( 2) the other 定指其它的 ⋯⋯ ,其后可接可数名词和单数,如: the other book 另外的一本书, the other map 另一张地图, 其后也可跟可数名词的复数形式,如: the other flowers 其他的花朵, the other teachers 其它的老师们,还可以接不可数名词, 如: the other water 剩下的水, the other beer 别的啤酒 other 表 “另外的 ”接复数名词, 如与具体数词连用, 则置于数词之后, 如: two other boys; 但与定冠词 the 连用时, other 要放在数词前。如: the other two boys Tony is going camping with _C__boys next Sunday .托尼将于下周日与另外两个男孩一起 去野营。 A . little two other B . two little other C. two other little D . little other two Mr Smith asked me to fetch three other recorders .史密斯先生让我再拿三台录音机来。 ( 3)others 其用法相当于复数名词, 此词不能用作定语, 表示的意思是 “不具体的某些 东西 ”,如: 4 This chemical is poisonous . Others are poisonous , too . ( others = other chemicals ) 但是如果 others 前用了 the ,则表示具体的别的东西。如: I don ’ t want these books . Please give me the others . ( the others = the other books ( 4)another ,作形容词时, 是指在原有的基础上再加一 (些) ,表示 “再一 (些) ”或 “另 外一个(些) ”的意思。 another 还可作代词,意思与作形容词时一样。 another+ 数词 =数词 +more eg:another one = one more I want another apple I want one more apple ★习惯用法: one another from one ⋯ to another the other day = a few days ago every other day/ week/year some ⋯, others ⋯ 如: I met Mr. Smith in the park the other day. 前几天我在公园里碰见了 Smith 先生。 While at the university , he went to the library every other day. 在大学时他每隔一天去图书馆一次。 Some people like football , others like volleyball. 有些人喜欢足球,有些人喜欢排球。 They are very different from one another. 他们互相之间差别很大。 When Americans moved from one place to another , they took their dialects with them. 当美国人从一个地方迁移到另一个地方时, 花费: pay、 spend、 cost、take Sb pay some money for sth.
