2、 与 will: be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些。 如：He is going to write a letter tonight. He will write a book one day. 2. be going to 表示根据主观判断将来肯定发生的事情，will 表示客观上将来势必发生的事情。 He is seriously ill. He is going to die. He will be twenty years old. 3. be going to 含有“计划，准备”的意思，而 will 则没有这个意思，如： She

3、is going to lend us her book. He will be here in half an hour. 4. 在有条件从句的主句中，一般不用 be going to, 而多用 will。如： If any beasts comes at you, Ill stay with you and help you. 掌握了它们的这些不同，你就能很好的区分 be going to 与 will 了。 一般将来时常见的标志词 含 tomorrow; next 短语； in + 段时间 ； how soon； by + 将来时间； 5. 祈使句句型中：or/ and sb. will

4、 do 例：Be quick, or you will be late = If you dont be quick, you will be late 6. 在时间/条件状语从句中，如果从句用一般现在时，主句用将来时 Unit 2 What should I do? 本单元目标句型： 1. Whats wrong (with you)?/ Whats the matter? 2. What should I do? 我该怎么办？ 3. You could write him a letter. 你可以给他写封信。 You should say sorry to him. 你应该给他道歉。 4

5、. They shouldnt argue. 他们不应该争吵。 5. Why dont you talk to him about it? = Why not talk to him about it? = You should/ could talk to him about it. = What/ How about talking to him about it. = Youd better talk to him about it.Unit 3 What were you doing when the UFO arrived? 本单元语法讲解 过去进行时（Past Progressiv

6、e Tense） 句型 S + was/ were + V-ing 例1：She was doing her homework at 8:30 yesterday evening 昨天傍晚八点半她正在做家庭作业。 例2：We were having supper at that time 那个时候我们正在吃晚饭 解说：如例1所示，在单句中使用过去进行时来表达时必须把该动作正在进行中的时间表明清楚，否则就不合逻辑了。例如：I was taking a bath yesterday. （错） （昨天我正在洗澡昨天24小时都正在洗澡吗？） 所以本句应该如例1来表达，或者用一般过去时表达如下： I t

7、ook a bath yesterday. 昨天我洗了澡 如果由上下文的文意，或者对谈中的话意可以了解“动作正在进行中的时间”，单句里就使用过去进行时来表达是很普通的，例如： A：I called you up yesterday evening. B：Did you? At what time? A：At around ten oclock. 大约在十点钟。 B：Oh, I was taking a bath then. 哦，当时我正在洗澡。过去进行时在表达上常用的句式是如例2所示和另一个一般过去时的动作相搭配。请观察下面的图解说明： 过去有二动作A和B（如图示），在B动作发生时稍早发生的A

8、动作正好在进行中，所以这种表达法通常都是复句（主句 + 副词从句）。例如： When I got up this morning, Mother was preparing breakfast in the kitchen. (今天早上我起床时妈妈正在厨房里准备早餐。“Mother .”是主句，“when ，”是副词从句。) 常用于修饰过去进行时的时间副词：过去的某一定点时刻（at + 过去的时刻），then (= at that time) (那时，当时)，all + 时间，“When / While / As ”等副词从句，etc Unit 4 He said I was hard-wor

9、king. 本单元语法讲解 直接引语和间接引语 （一）直接引述别人的原话，叫做直接引语；用自己话转述别人的话，叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内，间接引语则不用引号。直接引语改为间接引语时，除将引语部分变成宾语从句外，还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。 1. 时态的变化：直接引语变为间接引语时，通常受转述动词 said，asked 等的影响而使用过去化的时态，即把原来的时态向过去推，也就是一般现在时变。 一般过去时，现在进行时变为过去进行时等。 例如： Tom said to me,“My brother is doing hi

10、s homework.” Tom said to me that his brother was doing his homework. 2. 人称代词、指示代词、时间状语、地点状语等等的变化；根据意义进行相应的变化。 如： She asked Jack,“Where have you been?”She asked Jack where he had been. He said,“These books are mine.” He said that those books were his. （二）直接引语改为间接引语时，都使用陈述语序，但是因为原句的句式不同，所以变成间接引语时所用的连词

11、会有所不同。 1. 陈述句的间接引语：陈述句由直接引语变间接引语，由that引导，可以省略。 “I want the blue one.”he told us.“我想要兰色的。”他说。 He told us that he wanted the blue one. 他说他想要兰色的。 She said to me,“You cant do anything now.”她对我说：“此刻你无法做任何事情。” She told me that I couldnt do anything then. 她对我说那时我无法做任何事。 2. 疑问句的间接引语 直接引语如果是疑问句，变成间接引语后，叫做间接疑

12、问句。间接疑问句为陈述语序，句末用句号，动词时态等的变化与间接陈述句相同。引述动词常用 ask, wonder, want to know 等间接疑问句一般有三种： (1) 一般疑问句由直接引语变为间接引语时， 由 whether 或 if 引导。 如： “Has he ever worked in Shanghai?”Jim asked.“他在上海工作过吗？”吉姆问。 Jim asked whether/ if he had ever worked in Shanghai. 吉姆问他是否在上海工作过。 “Can you tell me the way to the hospital?”The

13、 old man asked. 那个老人问：你能告诉我去医院的路吗？ The old man asked whether I could tell him the way to the hospital. 那老人问我是否能告诉他去医院路。 (2) 特殊疑问句由直接引语变为间接引语时，仍由原来的疑问词引导。 如： “Which room do you live in?”He asked. “你住哪个房间？”他问我。 He asked me which room I lived in. 他问我住哪个房间。 “What do you think of the film?”She asked. 她问：

14、“你怎么看这部电影？” She asked her friend what she thought of the film. 她问她朋友怎么看这部电影。 (3) 选择疑问句由直接引语变为间接引语时，由 whether/ if or 引导。 如： “Is it your bike or Toms?”Mum asked. 妈妈问：“这是你的自行车还是汤姆的？” Mum asked whether/if it was my bike or Toms. 妈妈问这是我的自行车还是汤姆的。 “Does your sister like blue dresses or green ones?”Kate as

15、ked. “你妹妹喜欢兰色的裙子还是绿色的？”凯特问。 Kate asked whether/if my sister liked blue dresses or green ones. 凯特问我妹妹喜欢兰色裙子还是绿色的。 3. 祈使句的间接引语当祈使句变为间接引语时，间接祈使句的引述动词常用 tell, ask, order, beg, request, order 等，而把直接祈使句变成带to的不定式短语。如： Jack said,“Please come to my house tomorrow, Mary.”杰克说：“玛丽，明天请到我家来。” Jack asked Mary to g

16、o to his house the next day. 杰克请玛丽第二天到他家去。 The teacher said to the students,“Stop talking.”老师对学生们说：“不要讲话了。” The teacher told the students to stop talking. 老师让学生们不要说话了。 “Dont touch anything.”He said. “不要碰任何东西。”他说。 He told us not to touch anything. 他对我们说不要碰任何东西。 Unit 5 If you go to the party, youll ha

17、ve a great time! 本单元语法讲解 if 引导的条件状语从句。If 是连词，所连接的句子 叫条件状语 从句，表示假设或条件，意思是“ 如果的话”，用法如下： 1. 表示假设，表示将会发生和可能发生的事，或进行提醒警告。句子结构如下： If + 句子(一般现在时)，+ 主句（主语 will/ may/ can) + 动词） a. If you finish your homework , you can go out and play. b. If I have enough money next year , I will go to travel. 2. 表示真实条件、客观真理

18、、自然现象、定理定义、民 间谚语等，句型是： If + 句子 (一般现在时)，+ 主句 (一般现在时). 例： If you study hard, you are sure to succeed. If you put ice in a warm place, it turns into water. If a glass falls on the floor, it usually breaks. If you cook a banana, it becomes very soft. If a plant dont get enough light, it grows very tall

20、ong have you been living here? 你在这儿已经住了多长时间了。（“居住”动作从过去一直现在还在继续） 现在完成进行时和现在完成时的区别： 1. 现在完成进行时比现在完成时更强调动作的延续性； 2. 如果没有时间强调，现在完成进行时表示动作仍在进行，现在完成时则表示动作已经结束， 3. 现在完成进行时一般不适用于表状态的动词，而现在完成时则可。 Unit 7 Would you mind turning down the music? 本单元目标句型： 1.
