On July 17，a four­kilometer­wide piece enters the Earth’s atmosphere with a massive explosion.About half of the piece is destroyed，but the remaining part hits the South Atlantic at 200 times the speed of sound.The sea boils and a huge hole is made in the seabed.Huge waves spread outwards from the hole.The wall of water，a kilometer high，rushes towards southern Africa at a speed of 800 kilometers an hour.Cities on the African coast are totally destroyed and millions of people are drowned. Before the waves reach South America，the second piece of the comet lands in Argentina.Earthquakes and volcanic eruptions are set off in the Andes Mountains.The shock waves move north into California and affects all the Pacific Ocean.The cities of Los Angeles，San Francisco and Tokyo are completely destroyed by earthquakes.　Millions of people in the southern half of the Earth are already dead，and the northern hemisphere won’t escape.❶Because of explosions，the sun is hidden by clouds of dust，and the tem­perature around the world almost falls to zero number.Crops are ruined.The sun won’t be seen again for many years.Wars break out as countries fight for food.A year later，no more than 10 million people remain alive. Could it really happen? In fact，it has already happened more than once in the history of the Earth.The dinosaurs existed on the Earth for over 160 million years.Then about 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by an object in space.　The dinosaurs couldn’t bear the cold climate that followed and they died out.❷ Will we have the same end? 词汇积累 1．massive adj.　巨大的；强烈的；极具破坏力的 2．remaining adj.　剩余的 3．totally adv.　完全地 4．volcanic eruption　火山喷发 5．set off　引发；激起 6．hemisphere n. 半球 7．explosion n.　爆炸 8．clouds of dust 成团的灰尘 9．zero number　零度 10．crop n.　庄稼；作物 11．break out　爆发 12．no more than　仅仅 13．once adv.　一次 14．object n. 物体 15．bear v.　忍受 难句剖析 ①句意：在南半球数百万人已经丧生，而且北半球也难逃厄运。 分析：这是一个并列复合句。连词and连接两个并列的分句。 ②句意：恐龙无法忍受随之而来的严寒气候，它们灭绝了。 分析：这是一个由and连接的并列复合句。在前一个分句中含有that引导的定语从句，修饰先行词the cold climate。 [应用] 1．When the first piece hits the South Atlantic，it causes________． A.an earthquake B．damages to crops C．an explosion D．huge waves 答案：D 2．Why can’t the northern half of the Earth escape?

D．Because wars break out among countries. 答案：B 时事阅读 阅读提示 文章介绍了一种新型旅游方式——利用机器人模拟真实场景，让人们足不出户感受自然风光。 As an oceanographer (海洋学家)，I’ve spent many years developing robots to explore the ocean，and now we’re putting that technology to use in our JASON Project，a program that’s designed to inspire students and get them interested in science，technology，engineering and mathematics. In theaters throughout the country，we bring kids together and show them on large screens our live explorations of the large areas of the globe.Not only are the kids observers，but they can operate robots to make them move across the area while the images are transmitted back to them.The kids have the sensation(感觉) of really being on site with us. I believe advances in robot technology will one day become the key to a new kind of travel.In 10 or 15 years，people will have rooms in their houses that are able to simulate other environments.I like to call these rooms“ home domes ”— small theaters with screens and advanced equipment that can reproduce the sights，sounds，smells，and the feel of a desert，or a forest.From these rooms，I can see a market for travel robots in countries around the world.You can rent (租) a robot working in the rain forest，and then go into your home dome，where you yourself operate the robot.The equipment in the room will receive the relevant information in the robot’s environment and simulate it for you. Today，a high percentage of the world’s population never travels to a place more than 50 or 60 miles from home.And even a person with enough time can only see a part of the earth.But this new way of traveling will take much less time and money and allow people to see a lot more of the globe.And simulated travel will also help protect our planet.You can’t take large groups of tourists to look at gorillas (大猩猩).But a small robot，with no animals’ smell，can get very close to a gorilla and send the sights，sounds and smells back to a million people. 词汇积累 1．design v. 设计 2．engineering n.　工程学 3．throughout prep.　遍及；在……各处 4．live adj.　现场直播的；现场演出的 5．image n.　图像；影像 6．transmit v.　传输；发送 7．on site　在现场 8．advance n.　进展；进步 9．the key to...　……的关键 10．simulate v.　模拟 11．dome n.　圆顶体育场；圆顶状物 12．advanced adj.　先进的 13．simulated adj.　模拟的；仿真的 14．planet n.　行星 15．get close to　接近 难句剖析 句意：作为一名海洋学家，我花费了很多年研发机器人来探索海洋，现在我们正在把这项技术应用于一个叫“JASON Project”的项目上，设计这个项目的目的是激励学生，让他们对科学、技术、工程学及数学感兴趣。 分析：这是一个由and连接的并列复合句。前一个分句中含有spend time doing sth.结构，意为“花费时间做某事”。在后一个分句中同位语a program...解释说明JASON Project; program后的that引导定语从句，修饰先行词program。 [应用] 1．Without going outside，people in “home domes” can ________． A．enjoy a guided trip B．get very close to nature C．develop and operate robots D．send images back to scientists 答案：B 2．According to the text，simulated travel________． A．has been widely accepted B．takes lots of time and money C．is harmful to the environment D．is time­and­money­saving 答案：D 高考阅读 阅读提示 文章分析了不同购物袋的利弊，塑料袋造成了环境问题，尽管纸袋容易回收利用，但生产和运输需要更多的能源；环保专家认为塑料袋和纸袋都不是最好的选择，希望消费者长期使用可重复使用的袋子。 Steven Stein likes to follow garbage trucks.His strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter，including things that fall off garbage trucks as they drive down the road.What is even more interesting is that one of Stein’s jobs is defending an industry behind the plastic shopping bag. Americans use more than 100 billion thin film plastic bags every year.So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts (收银台).The bags are prohibited in some 90 cities in California，including Los Angeles.Eyeing these headwinds，plastic­bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume. Among the bag makers’ arguments : many cities with bans still allow shoppers to purchase paper bags，which are easily recycled but require more energy to produce and transport.And while plastic bags may be ugly to look at，they represent a small percentage of all garbage on the ground today.　 The industry has also taken aim at the product that has appeared as its replacement：reusable shopping bags.The stronger a reusable bag is，the longer its life and the more plastic­bag use it cancels out.However，longer­lasting reusable bags often require more energy to make.One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic. Environmentalists don’t dispute (质疑) these points.They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years. 词汇积累 1．end up　最后处于 2．a growing number of　越来越多的 3．prohibit v.　禁止 4．assume v.　认为 5．ban n.　禁止 6．purchase v.　购买 7．energy n.　能源 8．take aim at　瞄准，把目标对准…… 9．reusable adj.　可重复使用的 难句剖析 句意：尽管塑料袋看上去可能不美观，但是现在它们仅仅是地面上所有垃圾中的一小部分。 分析：这是一个主从复合句。while引导让步状语从句，意为“尽管”。 方法归纳 利用上下文的紧密联系破解词义猜测题 以文章第2题为例： 画线词上文原句：“The bags are prohibited in some 90 cities in...” 画线词下文意义：塑料袋制造商雇用像Stein这样的科学家来拿出理由说明他们的产品不像大多数人认为的那样对地球有那么大的坏处。 由此推出画线词意思：对塑料袋使用的禁令。 [应用] 1．What has Steven Stein been hired to do? A．Help increase grocery sales. B．Recycle the waste material. C．Stop things falling off trucks D．Argue for the use of plastic bags. 答案：D 2．What does the word “headwinds” in Paragraph 2 refer to? A．Bans on plastic bags. B．Effects of city development. C．Headaches caused by garbage. D．Plastic bags hung in trees. 答案：A $$
