英语中有哪些时态它们都有哪些象征性的

英语时态有很多很多，与汉语差异很大，要花功夫学，特征就在谓语的型式上，不过也不是非常难。1。语态：主动、被动；2。时间：现在、过去、将来；3。句式：一般式、进行式、完成式、完成进行式。因而主动有 12 个时态；被动也有12个时态，但有 3个不用了，常用的是 9 个。主动与被动合起来是 21个。主动12个时态：（以动词 do 为例）Simple Continuous Perfect PerfectCotinuousPresent I do I am doing I have done I have been doingPast I did I was doing I had done I had been doingFuture I shallll do I shallll be doing I shall have done I shall have been doing被动语态也有12种时态，常用的有9种：Simple Continuous Perfect Perfect ContinuousPresent is sent is being sent has been sent *has been being sentPast was sent was being sent had been sent *had been being sentFuture will be sent will be being sent will have been sent *will have been being sent有 “*” 号的是基本上不用的。

英语中的of有几种用法

介词 of 用法详解（摘自《英语介词详解词典》）1. （表所有或所属关系） ……的：The windows of the house are broken. 房子的窗户破了。It's the custom of the country. 这是这个国家的习俗。Do you know the name of the plant？你知道这种植物的名字吗？He knew the result of the exam yesterday. 他昨天知道了考试成绩。The children of the poor couldn't go to school in those days. 那时穷人的孩子上不了学。【用法说明】

（1）表所属关系后接人称代词时，通常只能是名词性物主代词，而不能是人称代词的宾格形式。如：他是我的一位朋友。误：He is a friend of me.正：He is a friend of mine.另外比较：他是我父亲的一位朋友。正：He is a friend of my father. （强调“他”对“父亲”的交情）正：He is a friend of my father's.（强调“父亲”对“他”的交情）有人认为只有上面第二句是对的，第一句不对。其实两者都是对的，只是强调重点有所不同。

（2）注意以下表达在含义上的区别：a photo of my girlfriend 我女朋友的照片（照片上的人是我的女朋友）a photo of my girlfriend's 我女朋友收藏的一张照片

（3）比较以下两种含义相同但表达方式不同的结构：my aunt's son =a son of my aunt 我姑妈的儿子 Africa's future=the future of Africa 非洲的未来 the book's author=the author of the book 本书的作者但强调“所有”的意思时，通常不用“of+名词”的形式。如：误：Where's the handbag of my mother？正：Where's my mother's handbag？我母亲的手提袋在哪里？注：偶尔也可见到 the handbag of my mother 这样的表达，学生最好避免。2. （表部分） ……之中的……，……的：One of my friends has gone abroad. 我的一个朋友出国了。Three of the houses are on fire. 其中三座房子着火了。Of all choices, this is the best. 各种办法中，这最好。He is a member of the football team. 他是足球队一队员。3 （表数量、分量、种类等） ……之量的，……份的，……种类的。如：Please give me a glass of milk. 请给我一杯牛奶。There were ten of them. 他们一共10个人。We need five tons of coal. 我们需要5吨煤。She bought two pairs of shoes. 她买了两双鞋子。What kind of fruit do you like？你喜欢哪种水果？【用法说明】two cups of tea,two glasses of beer 等，也可说成 two teas, two beers。因为 tea, beer 等既可用作不可数名词，也可作可数名词，表示“一杯茶”、“一杯（瓶）啤酒”等。但是不能说 two milks 之类的。4. （表材料、成分）由……组成（或构成）：She bought a dress of silk. 她买了件丝连衣裙。The book consists of several chapters. 这本书有好几章。This is a family of five. 这是一个五口之家。【用法说明】a table of wood（木头桌子）可视为是 a table made of wood 或a table which is made of wood之省略；The house is of stone.（这房子是石头建的）可视为在 of 前省略了动词 built。5. （表同位关系）：We live in the city of Beijing. 我们住在北京市。There were only three of us. 到的只有我们三个人。At the age of 18 he joined the army. 他在18岁那年参军了。【用法说明】比较以下结构有 the 与无 the 含义不同：two of us 我们当中的两个人（指部分，即我们一共不只有两个人）the two of us 我们两个人（指全部，表同位关系，即我们一共只有两个人）6. （表动宾关系）：Loss of health is worse than loss of wealth. 失去财富比失去健康更糟。The Party pays great attention to the education of children. 党对儿童教育非常重视。The writing of the letter took me three hours. 写这封信花了我3个小时。Columbus' discovery of America occurred in 1492. 哥伦布于1492年发现美洲。【用法说明】of 前通常是一个表示动作意义的名词，与 of 后的名词构成一种逻辑上的动宾关系。又如：love of one's country 爱国（比较：love one's country） the telling of lies 说谎（比较：tell a lie） 7. （表主谓关系）：We waited for the arrival of the next train. 我们等待下班火车的到来。You must try to gain the support of the voters. 你必须设法得到选民们的支持。【用法说明】这里说的主谓关系，指的是of 后的名词与 of 前的名词（表动作意义）构成一种逻辑上的主谓关系。又如：the shooting of the hunters 猎人的射击（比较：the hunters shoot） the breathing of a fine swimmer 优秀游泳运动员的呼吸（比较：a fine swimmer breathes） 8. （表性质或特征）：Birds of a feather flock together. 物以类聚。What he says is of great importance. 他讲的话很重要。His wife is a woman of ability. 他妻子是一位有才干的女子。China is a big family of many nationalities. 中国是一个多民族的大家庭。【用法说明】用于此义时，与age, shape, size, colour, height等名词连用，表示特征。又如：They were both of middle height. 他们俩中等个子。These boxes are of the same size. 这些盒子都是同样大小的。
