牛津译林版英语八年级下册Unit4 语法精讲：must和have to用法
语法精讲：must和have to用法一、must的用法(1) must表示“必须”，“应该”。
否定式must not(mustn’t)表示“不应该，不许可，不准，禁止”等。
在回答带有must的问句时，否定式常用need not(needn’t)或don't have to 表示“不必”，而不用must not (mustn’t)。
如：The work must be finished as soon as possible.这件工作必须尽快完成。
You mustn’t speak like tha t.你不能那样说话。
—Must I be home before eight o’clock? 8点之前我必须回家吗？—Yes, you must./No, you needn’t./No, you don’t have to. 是的，必须回家。
/不，不必。
(2) must表推测，①一般只用于肯定句中，译成汉语“一定”，“必定”。
如：There must be some mistakes.肯定有一些错误。
You must be very tired.你一定很累了。
②如果表示对过去事情的推测，就用must+完成时。
如：You must have left your umbrella in the theatre.你一定把雨伞丢在剧院里了。
His car is still here. He must have gone by bus.他的车还在这里，他一定乘公共汽车走了。
③当must表推测之意时，其否定形式常用can not而不用must not。
He can’t have been to your home. He doesn’t know your address.他不可能到过你家，因为他不知道你的住址。
What can he be doing at this time of night?夜晚都到这个时候了，他究竟在干什么呢？(3) must表必然性You must catch cold if you don’t put on more clothes.如果你不多穿些衣服，必然感冒。

八年级下册英语Unit4语法概念讲解以上方框中的句子讲述的是一个新的语法：直接引语和直接引语(Direct speech and Reported speech)。
1. 定义：(1)直接引述别人的原话，叫直接引语。
(直接引语一般前后要加引号)Mr. Black said, "I'm busy." 布莱克先生说：“我很忙”。
(2)用自己的话转述别人的话，叫间接引语。
(间接引语在多数情况下构成宾语从句，不用引号)Mr. Black said that he was busy. 布莱克先生说他很忙。
2. 直接引语变间接引语在以下几方面发生变化：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要调整。
(1)直接引语是陈述句，变成间接引语时要用连词that引导，连词that也可省略。
Tom said, "We are listening to the pop music."→Tom said that they were listening to the pop music.(2)直接引语是一般疑问句，变成间接引语时要用连词if或whether引导。
从句再改成陈述句语序，时态随主句的时态而变化。
主句中的谓语动词为said时，要改为asked. 没有间接引语时，可以加一个间接宾语(me, him或us等)。
"Do you know where she lives?" he asked.→He asked if / whether I knew where she lived.(3)直接引语是特殊疑问句，变成间接引语时用相应的疑问词引导，从句要改成陈述句语序，时态随主句的时态而变化。
如：who, whom, what, whose, how, when, why, where等。
"What can I do for you?' he asked me.→He asked (me) what he could do for you .(4)直接引语是祈使句，变成间接引语，要将祈使句的动词原形变为带to的不定式，并在不定式的前面根据句子的意思加上tell, ask, order等动词，其句型为：tell / ask / order sb. to do sth.的形式。
若原句是否定句，变成间接引语时在动词不定式前加not，即tell / ask / order sb. not to do sth.的形式。
"Stop making so much noise, children." he said.→He asked the children to stop making so much noise."Don't tell him the news." she said.→She told me not to tell him the news(5)直接引语是客观事实、永恒真理，变成间接引语时时态不变，用一般现在时。
The teacher said, "The sun rises in the east and goes down in the west."→The teacher said that the sun rises in the east and goes down in the west.总结：直接引语变直接引语的方法如下：人称变化跟句意(一随主，二随宾，第三人称不更新)所用时态看主句(主现在，从随意，主过去，从过去)(注意：当转述客观真理时，无论主句用何种时态，从句都用一般现在时) 陈述语序要牢记引导词看句式(陈述句用that, 一般疑问句用if或whether, 特殊疑问句用特殊疑问词，祈使句动词变to do)3. 在间接引语中要根据意思将直接引语中的人称、时态和表示时间、地点等的词作相应的改变。
(1)人称的变化：Direct speech直接引语→ Reported speech间接引语I am mad at Marcia. → She said she was mad at Marcia.I like English. → He said he liked English.We are having a class. → They said they were having a class He can speak English. → Lucy said he could speak English.I will go shopping after school. → She told me she would go shopping after school.(2)时态的变化：主句的谓语动词是一般过去时，直接引语变间接引语时，从句的谓语动词在时态方面作相应的变化。
(如主句的谓语动词是现在时，从句的时态无须变化。
)(3)指示代词、地点状语、动词和时间状语的变化：注：直接引语转换成间接引语时的变化根据实际情况而定。
假如就在当天转述，today, yesterday, tomorrow等就不需改变;如果在当地转述，here也不必改为there, come 也不必改为 go.八年级下册英语Unit4语法习题Ⅰ. 句型转换(1) "You can do better." My math teacher said to me.

(变为直接引语)Dave said, "____ ____ ____ noodles for breakfast."以上(1)(4)小题直接引语的从句是陈述句直接用连词that引导即可，不过人称与时态和时间状语要做相应的变化;(2)小题则是对从句的提问，关键要把握好时态，看划线提问要提问什么即可;(3)题和(5)题直接引语的从句分别是一般疑问句和特殊疑问句在变成间接引语时引导词分别是if / whether和相应的特殊疑问词，语序要变成陈述句的语序;(6)小题则是祈使句的否定形式，变成间接引语时在动词不定式前加not，即tell / ask / order sb. not to do sth.的形式;(7)小题要考察学生的逆向思维由间接引语变成直接引语，也要注意人称、时态和状语的变化。
