1、第四讲：Unit 2 语法篇_掌握单词和短语时间状从句一般现在时的被动语态1. among prep. 在之中【语境领悟】*It is a time for a special dinner among family and friends. 这是一个在家人和朋友之间吃顿特殊晚餐的时间。*The teacher sat among the children. 老师坐在孩子们中间。*I am sitting between my parents. 我正坐在我父母中间。来源:学科网2. Football is also important at Thanksgiving, with many te

2、ams playing games. 足球在感恩节也是很重要的, 很多队都在比赛。【句型剖析】(1)with many teams playing games是“with +宾语+v. -ing形式”构成的复合结构, 在句中可以作定语或状语。这一结构中的宾语补足语可由形容词、副词或介词短语等充当。(2)with的复合结构: 【归纳拓展】with的不同含义 词义用法同一起; 和其后一般接表示人的名词或代词有; 带有其反义词为without, 其后接名词、代词或动名词用其后一般接表示工具的名词来源:学科网2.语法梳理状语从句: 状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义

3、状语从句可分为时间状语从句，地点状语从句，条件状语从句， 原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。1. 时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：It was raining hard（rain hard 下大雨） I got to school yesterday.While he was doing his homework, the telephone rang.As he walked along（沿着走） the lak

4、e, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：Ill ring you up as soon as I get to New York.I will tell him everything when he comes back.He wont believe it until he sees

5、 it with his own eyes.(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到才”, “在以前不”, 谓语动词可用瞬间动词。例如：The young man read till the light went out（熄灭）.Lets wait until the rain stops. We wont start until Bob comes. Dont get off（从下来） until the bus stops.【Till是指直到某一特定事件发生的时候，而

6、在那个时刻之后，该事情或状况仍将持续。 Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里from morning till night，till/until是不能替换的，】2.when, while 的用法 when和while与过去进行时有着密切的关系，他们作从属连词时都有“当.时候”之意， 用法稍有不同： when引导的时间状语从句的谓语动词可以是短暂性动词，也可以是延续性动词，而while引导的时间状语从句中的谓语动词只能是延续性动词。 when引导的从句谓语动词如果是短暂性动词则用一般过去时，主句是延

7、续性动词则用过去进行时，从句动作发生在主句动作的时间段之内（长动作用过去进行时，短动作用一般过去时）；如果主句和从句两个谓语动词都是延续性动词则全部用过去进行时,这时when和while都可以用。 when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生。when +短/延while +延 when和while两个词还可以用作并列连词，但意思不同，when相当于“在那时”，等于at that time或just then;而while则相当于“而；却；但是”；相当于but,表示对比关系。（这一点暂时可以不掌握）eg. I was

8、playing computer games when my father got home. = When my father got home,I was playing computer games. (2) Mother was cooking when/while I was doing my homework. = When/While I was doing my homework, mother was cooking.3.常见的时间状语从句: (1)when引导的从句: 表示主句的动作和从句的动作同时发生, 或从句的动作发生在主句动作之前。 (2)while引导的从句: 表示

9、“当过程中”, 强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为, 所以从句中要用延续性动词, 并且延续性动词常用进行时态。 (3)as引导的时间状语从句: 由as引导的时间状语从句, 表示“当的时候, 一边一边, 随着”。其从句的主语与主句的主语往往是同一人或物。 (4)before引导的从句: 一般表示主句的动作发生在从句动作之前。例如: I didnt know any English before I came here. 我到这儿来之前, 一点英语都不懂。(5)after引导的从句: 表示主句的动作发生在从句动作之后。例如: Aft

10、er he locked the door, he left. 他锁上门, 就走了。(6)since引导的从句: 表示“自从以来”, 从句中的动词一般表示动作的起点, 用一般过去时。主句中的动词表示动作延续的情况, 一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态, 可用一般现在时。(7)until引导的从句: 表示“直到”, 主句和从句都用肯定式。例如: They worked until it was late. 他们一直工作到天黑。 表示“直到才”, 主句用否定式, 从句用肯定式。 例如: She didnt go to bed until she finishe

11、d her homework. 她一直到写完作业才睡觉。 (8)as soon as引导的从句: 表示“一就”, 强调动作紧密相连。例如: As soon as she came to the classroom, she began to read English. 她一到教室, 就开始读英语。1.
