Science fiction writers often write about what will happen in 'tomorrow’s world'. Have you ever read any science fiction stories? ‎ Among the most famous science fiction writers are Jules Verne and H. G. Wells. Read the following summaries of two of their novels to help you prepare your own science fiction. ‎ Journey to the Centre of the Earth by Jules Verne In 1863, Professor Otto Lindenbrock found a secret message in an old book he had recently bought. The message spoke of a trip to the centre of the Earth through a volcano in Iceland. Immediately, he got his things packed and went to Iceland, forcing his nephew Axel to go with him. ‎ In Iceland, the Professor hired a guide named Hans. When the three of them reached the volcano, they journeyed underground through a small cave. After many days, they came to a vast room with a large ocean inside. On the shores of this ocean, there was a forest and huge mushrooms. High above, the sky was filled with gas that gave light like the sun. ‎ The three men built a small boat and set sail. All of a sudden, two dinosaurs rose to the surface and began to fight each other. The small boat was almost sunk by the dinosaurs before they were able to get away. [来源:学*科*网Z*X*X*K]‎ They sailed to shore and explored the forest. They came across huge insects and many strange creatures. As they were wandering around, they noticed a man sitting against a tree in the distance-he was at least four metres tall. The men became afraid, and ran back to the boat. ‎ They set sail again, and saw what looked like an exit, but it was blocked by rocks which had fallen down from the ceiling. They made a bomb to blow up the rocks. After the bomb exploded, their boat rushed wildly forward into a large hole. The boat floated down with the water. It was too fast for them to escape. They could only hold on to the boat in terror. ‎ Finally they reached the bottom of the hole. Then the water began to push them up. They floated upwards for miles. The water rushed beneath them, pushing them out into the sunlight. They now found themselves in a volcano in Italy-their adventure was over, but a new one was about to begin. ‎ The Time Machine ‎ by H. G. Wells Here is my Time Machine. This is where you sit, and with these two white handles, you can travel into the future or the past. ‎ I finished the machine just last week, and decided to use it to see the future. As I pulled one handle, the world around me became foggy. Days and nights zipped by and everything changed before my eyes. Buildings and cities appeared and disappeared in a flash. Finally, I heard a loud thunder, and everything stopped. There was a city in front of me that appeared very old and worn.‎ I was now in the year AD 802,701, and mankind had evolved into two races, the Eloi and the Morlocks. The Eloi were small and like children. They lived above the ground and spent all of their time at play. Unlike the Eloi, the Morlocks looked like white beasts. They lived underground, where they kept machines running so that the Eloi would be happy and well fed. ‎ At first, I thought that the Eloi had forced the Morlocks to do all of the work so that the Eloi could play. However, later I came to see that I had the wrong impression: the Morlocks were the real masters. They took care of the Eloi because they lived by killing and eating them. The Morlocks even tried to catch and kill me, but luckily I was able to use the Time Machine to escape. ‎ I then travelled 30 million years into the future. I was now on a beach with an ocean in front of me, but there was neither wind nor waves, and there seemed to be little life. I went still further into the future, and the sun grew larger, redder and darker, and the Earth became cold and covered in frost. Everything was still—there was no life or movement at all. ‎ As the world turned to complete darkness, I pulled the other handle, and found myself back in my house in the present day. Only three hours had passed.[来源:Zxxk.Com]‎ Step 1: Read and learn ‎ ‎◆ Listen to the text and grasp the general spirit of the text ‎ Language focus: ‎ ‎◆ 将来时的表达式 知识探究：‎ If you work hard， you'll succeed. 如果努力，你就会成功。 ‎ I'm afraid it is going to snow.恐怕天要下雨了。 ‎ You'll have to pay more if you are to have another drink.要想再喝一杯你得多付钱。 ‎ I'm just finishing my work.我马上就完成工作了。 ‎ He was just about to leave when the phone rang. 他正要走，这时电话响了。 ‎ The train leaves at 8: 30.火车8点半开。‎ 归纳整理：‎ ‎1) will / shall do表示纯粹的将来或临时做出的决定，也可表示一种必然趋势。 ‎ ‎2) be going to指打算准备做的事或根据判断肯定要发生的事。 ‎ ‎3) be to do则不能表示不受人们意志控制的将来动作。 ‎ ‎4) be doing指按计划安排最近要做的事，常常带时间状语，多用于go， come， leave， start， arrive， stay， meet， get， set等短暂性动词。 ‎ ‎5) be about to do单纯表示即将发生的动作，常与when 连用，意为"这时"，但不与时间状语连用。 ‎ ‎6)一般现在时表将来.表示早已计划好，到时一定发生的事，也可表示按时间进程或时间表的安排，到时一定要发生的事。‎ 题练落实：‎ D) 1. ---When shall we restart our business?‎ ‎---Not until we _______ our plan.‎ ‎ A. will finish B. are finishing C. are to finish D. have finished C) 2.

How to keep sustainable development is a big problem facing our planet. ‎ ‎ The present situation is worrying. First, natural resources are becoming less than before. Second, as some people are not aware of the importance of the environmental protection, the problems with it remain extremely serious to some degree. The gap between the rich and the poor has the tendency to become wider and wider.‎ ‎ To our great joy, many countries have taken action. On one hand, they have made relevant laws and regulations and put large amounts of money to the environmental protection. On the other hand, popularized educational as well as international cooperation is being carried out.‎ ‎ As for myself, I should take the responsibility to devote myself to sustainable development, or our future and the lives of our children and our grandchildren will be in danger.‎ 板书设计 当堂作业 课外作业 教学札记 ‎ ‎
