江苏译林版英语九年级下册第4单元知识点解析讲义课件1(含习题和答案)
九年级英语译林版第四单元知识点
九年级英语译林版第四单元知识点英语作为全球通用语言的重要性日益凸显，九年级的学生们正处于英语学习的关键阶段。
译林版九年级英语教材第四单元是一个重要的学习阶段，涵盖了许多重要的知识点。
本文将对该单元的知识点进行探讨和总结。
首先，第四单元主要介绍了陈述句和疑问句的构成及使用方法。
在日常交流中，我们通常使用陈述句来表达自己的观点、描述事物或者给出指示。
而在询问问题时，我们则需要使用疑问句。
疑问句分为一般疑问句、特殊疑问句和选择疑问句等不同类型。
通过学习这些知识点，学生们可以更加准确地表达自己的想法和询问对方的意见。
其次，第四单元还介绍了一些日常生活中常用的交际用语和表达方式。
例如，当我们需要向对方提供帮助时，可以用“Can I help you?”来表示。
而当我们想要请求对方的允许时，可以使用“May I...?”或者“Do you mind if...?”等表达方式。
这些交际用语的学习可以帮助学生们更好地与他人进行交流，增进彼此间的理解和友谊。
此外，第四单元还涉及了一些动词的变位规则。
在英语中，动词的时态和语态变化很多，因此学生需要通过掌握动词的不同形式来正确地表达自己的意思。
英语中常见的动词时态包括一般现在时、一般过去时、一般将来时等。
此外，英语中还有被动语态、进行时和完成时等不同的语态形式。
通过学习这些动词变位规则，学生们可以提高自己的语法水平，使自己的英语表达更加准确和地道。
在第四单元的学习中，还有一个重要的内容是阅读理解。
阅读理解是英语学习中的一项重要能力，也是提高综合语言运用能力的重要手段。
通过阅读不同的文章，学生们可以了解不同的文化背景、思维方式以及社会现象。
在阅读理解过程中，学生们需要掌握一些技巧，如寻找关键词、理解上下文等，以帮助他们更好地理解文章的含义并正确回答问题。
总而言之，九年级英语译林版第四单元涉及了多个重要且基础的知识点。
通过学习这些内容，学生们可以提高自己的英语表达能力，并为进一步学习英语打下坚实的基础。

Unit 4 Life on Mars一、Comic Strip & Welcome to the Unit(一)(二)、对话1. Hobo: Wow, I’ve never thought about travelling into space.Eddie: Me neither.Hobo: How do you like life on Mars?Eddie: I hate it.Hobo: Why do you hate it? I thought you liked Mars.Eddie: It’s this helmet.Hobo: I can’t get to my food.2. Daniel: What would it be like to live on Mars?Amy: There’s less gravity on Mars. We’d probably need to wear special boots.Daniel: Yes. And we might need sleeping bags too.Amy: I agree. Also, there’s no fruit or vegetables, so we would have to eat dried food.Daniel: Well… that sounds quite boring! But there would be no pollution on Mars.Amy: I hope so.二、Reading((二)、课文Moving to MarsSome people believe that humans could live on the planet Mars by the year 2100. Our own planet, the Earth, is becoming more and more crowded and polluted because of the rapid increase in population. It is hoped that people could start all over again and build a better world on Mars. Here is what life there could be like.At present, our spacecraft are too slow to carry large numbers of passengers to Mars—it would take months. With the development of technology, by the year 2100, the journey might only take about 20 minutes in spacecraft that travel at the speed of light! However, the spacecraft would travel so fast that the journey to Mars might be quite uncomfortable. Many people would feel ill.Humans cannot survive without water, oxygen or food. So far, nobody knows whether there would be enough water or oxygen on Mars for people there. Moreover, scientists are not sure whether plants could grow on Mars. Food would most probably be in the form of pills and would not be so tasty.Gravity could be another problem. The gravity on Mars is only about three-eighths of that on the Earth, People would have to wear boots that are specially designed to prevent themselves from floating off into space.Compared with life on the Earth, life on Mars would be better in some ways. People would have more space. They might live in houses with huge comfortable rooms. Also, robots would do most of their work so that they could have more time to relax.There would probably be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online schools with “e-teachers”.Life on Mars would be interesting as well as challenging.三、Grammar：大声朗读背诵书后P79语法及例句简单句和复合句之间的转换（二）将复合句改为简单句1. I can’t pass the exam if you don’t help me.I can’t pass the exam ______your ______.2. Do you mind if I smoke here ?Do you mind ______ ______ here ?3. The teacher who is wearing glasses teaches us English.The teacher ______ glasses teaches us English.4. The girl who is dancing on the stage is my sister.The girl ______ on the stage is my sister.5. Don’t forget to turn off the gas before you leave the kitchen.Don’t forget to turn off the gas ______ ______ the kitchen.6. She won’t go to see the play because she has lost her ticket.She won’t go to see the play ______ ______losing her ticket.7.

I can’t finish the work in time without your help .I can’t finish the work if ______ ______ ______ me .四、Speak up and Task(一)(二)、Speak upDaniel: Would you like to live on Mars , Sandy ?Sandy: I’m not sure if it’s worth the risk. It worries me.Daniel: Why? It would be quite safe .After all, humans have already been to the Moon. Sandy: Maybe you’re right ,but we might get ill from living there.Daniel: I don’t think so, Sandy. It’s just a different kind of life. It would be great to live on another planet .Sandy: What about all your friends here on the Earth if you go to Mars?Danel: I want you all to come too.Sandy: OK. If we all go together , it should be fun.(三)、Task (P63 Part B)On Mars, we use Mars dollars. We get about M$10 for every￥1 ,but we never see any of it! Mars dollars are electronic and are stored in the ⑴Planet Mars Bank. A very popular form of entertainment is online games .They make us feel like we are really inside the games! There are also many ⑵online theatres .There are ⑶two moons to visit, but most people may prefer to watch the amazing low-gravity ⑷basketball games instead.There are lots of ⑸shopping malls on Mars .They sell ⑹space clothes and food.Most things are cheap on Mars .Goods from the Earth are ⑺hard to find.The public transport system is ⑻comfortable and it produces ⑼no air pollution.If you want to drive ,you can buy a car which ⑽floats in the air!Life on Mars is interesting, isn’t it?。

拓展：Neither /nor和so 引导的倒装结构中的助动词/情态动词/连系动词be，应与前句的谓语部分，以及后面的主语，在人称和数上保持一致，时态和前句保持一致。
