But in fact if you master some reading skills, you will find reading easier. Guessing the main words from the meaning of the context is a basic skill. Now look at the sentence on the blackboard: Since only one sixth of the land is arable, Japan relies on imported（进口） food. From the subject “one sixth of the land”, we know “arable” is a kind of land. From “imported food”, we can decide “arable” means “suitable for farming”. Do you know how to guess a word? Ss: Yes.

The world is dark and dirty, and human beings have no room for happiness and fun. 3.

They will try to teach AXL about love and friendship in order that they can live together with the machines like friends in the future. FStep . WritingT: Now you have known only when AXL is taught about love and friendship, will AXL and human beings live together and will the world be beautiful again. Now you must write a letter to AXL to tell it about love and friendship. Three tips have been given. Please discuss them in groups to finish the task. （Teacher gives the students enough time to prepare it and then asks two students to read their letters. At last, teacher may give the suggested letter on the screen. ）One possible version: Dear AXL: My name is Tom. Im a human being. Seeing the world is getting worse, Im greatly worried about that. In the past, as we all know, the earth was a beautiful place, where all the beings and creatures were living happily. The ground was covered by grass and trees with flowers everywhere. People were doing their favorite activities in the park with birds singing. How happy we were! Who made the world so colorful? It was human beings and you robots that made our world full of happiness and gay. But now, you see, everything has changed. Can you see a clear sky and green grass? Can you see happy human beings and animals? Why do thins look like this? I think it is all because of your robots. In the past people treated everything in the world as friends. We lived and took good care of each other. With the help of your robots we had a happy world. But with your development, you order us to do everything without proper plan and friendship. So now the world is dark and dirty without happiness and fun. If you want a better world, I advise you to have some human beings help you because they know how to make our world full of love and friendship. What do you think of my advice? Im sure you are wise enough to take my advice. If so, our world will be the same as what it was. How happy we all will be! Let us bee friends and live happily. Yours sincerely, TomFStep .

Record after Teaching_Reference for Teaching一、异域风情Ten million mobile phones bee health problemViennaA new problem has appeared with the mobile phones in Austriathey may end up as a mountain of poisonous waste, said the newspaper Standard on Wednesday. The paper pointed out that Austria had one of the worlds highest mobile phone densities（密度）. The eight million Austrians shared ten million “mobiles”. But four million of the mobile phones were no longer used and just lying about. It could be dangerous if they, and the millions more after them, were thrown in the waste material, warned Karin Buechl-Krammerstaetter of the Vienna Environment Office. “Ten million mobiles have 700 tons of accumulators（蓄电池）（for recharging them）, and in the long term that means 700 tons of dangerous waste. ”“Accumulators contain numerous substances dangerous to health and the environment, such as the heavy metal cadmium（镉） which is poisonous and classified as causing cancer”, said the environment expert. She made an appeal to the public not to throw their old mobile phones away. “In the end the accumulators will get to a garbage depot（仓库） or incinerator（焚化炉） . From there the harmful substances will reach the environment, because depots and incinerators are not suited to the disposal（处理） of dangerous waste. ”Buechl-Krammerstaetter pointed out that shops selling mobile phones were limited by law to accept the accumulators of old ones back without charge, and see they were suitably disposed of. 二、知识归纳（一）表示“建议”常用表达归纳（1）Useful ExpressionsI wonder if youve ever thought of going to the countryside for a change. 我在想，你是不是曾想过去农村换换环境。I think it might be a good idea to take more exercise. 我想多做运动也许是个好主意。Have you ever thought of asking your teacher for help? 你想过找你的老师求助吗？Why dont you/Why not have another try? 为何不再试一次?

The news spread throughout the country. 这个消息传遍了全国。It rained throughout the night. 雨下了整整一夜。throughout作副词，意思为“到处、全部、处处、始终、彻头彻尾”。e. g. The room is painted throughout. 这屋子全部油漆一新。The boy remained silent throughout. 那男孩始终保持沉默。（2）all over意为“在（遍及）的各部分”，只接表示地点的名词。e. g. puters will be used more and more in the future all over the world. 将来全世界要越来越多的使用电脑。The disease spread all over the country. 疾病在全国蔓延开了。all over作副词，意思为“到处都是、全部结束”。e. g.

If you feel ill, you may get in touch with the doctor by phone. 如果你感觉不舒服，可以用电话与医生取得联系。（2）keep in touch with“与保持联系”表示状态，可与一段时间连用。e. g. We have always kept in touch with our friends in America by phone. 我们一直与我们的美国朋友保持联系。（三）be used for, be used to do, be used as（1）be used to do实际上是use sth. to do的被动式。e. g. Wood is used to make paper. 木头可用来造纸。（2）be used for是“被用作”，许多时候可能和“be used to do”互换。如上例也可表示为：Wood is used for making paper. e. g. Paper can be used for writing. =Paper can be used to write on. 纸可以用来写字。（3）be used as 是“被用来作为”，as是介词。e. g. A check of 1 500 was used as a book mark by Einstein. 爱因斯坦曾把一张1500美元的支票当书签用。（四）add up, add up to, add to, addto这四个动词短语均与“加”有关，但用法不同。（1）add up意为“加起来”。up为副词，宾语若为代词，应注意置于中间。如：Now try to add up these figures. 现在想办法把这些数字加起来。You havent add them up right. 你没有把他加对。（2）add up to的意思是“加起来总和是，总共有”。后常跟表示数字的词作宾语。另外，add up to还有“（总起来看）说明，意味着”的意思。如：The money he spent added up to more than $1 000. 他花的钱加起来有一千多美元。It all adds up to thishe is a selfish man. 所有这些说明一点他是一个自私自利的人。（3）add to意为“增加，增强”，to为介词，宾语位于to之后。如：This adds to our difficulties. 这会增加我们的困难。The house has been added to from time to time. 这房子曾经一再地扩建。（4）addto意为“把加到上/里”。如：You can add what I said just now to your report. 你可以把我刚才说的那些话加进你的报告。if you add 5 to 5, you get 10. 五加五得十。She added some sugar to the tea. 她加了一点糖到茶里。四、能力训练（一）单句改错1. Why not to e to our home for the party? 简析：去掉e前的to。Why not do sth. ? 是表示建议的常用句型，not后跟动词原形，也可用Why dont you do sth. ? 2. Swimming is a great fun. 简析：去掉a。fun是不可数名词，通常不与冠词a或the连用。3. puters can be used to doing a lot of things. 简析：将doing改为do。be used to表示被用来做某事，to是不定式符号，其后接动词原形。如果它表示“习惯于做某事”时，to则是介词，后接名词、代词、动名词。4. She gave me a lot of valuable advices. 简析：advices改为advice。advice当建议、忠告讲时，是不可数名词。5. The title boy didnt dare crossing the street by himself. 简析：将crossing改为to cross。dare作行为动词，后接不定式作宾语。6. Mr Greens family are going to London on the holiday. 简析：on改
