Unit 3-1 Listening

There are many forms of lives on earth, including human beings. Life exists in a variety of conditions. Some forms of live live in the watery environment, like the oceans. Other forms of lives can be found in very dry areas like desserts. However, for any form of live to exist, conditions must be right. When the conditions aren’t right, that form of lives can extinct. To become extinct means to die out completely.

Conditions must be right for life to exist. Millions of years ago, there were forms of lives that no longer exist. When condition changed, this form of life died out. One extinction event happened about 250 million years ago. This is the largest extinction event of all time. Many forms of lives become extinct. 96% of all lives in the oceans died out. Most insects also became extinct. This event happened over a period of several million years. The causes of this extinction event are still unknown. Possible causes include largest volcanic eruptions and global warming. Some scientists believe that there were several causes. They believe that a series of events caused the extinctions. Scientists are working for better understand what really happened.

In modern times, we human beings face changing conditions. For humans to live, we need clean air and clean water. Pollution is now a growing problem around the world. Pollution poisons the air and water that we depend on. Polluted air makes people sick and afraid to get outside. Polluted water poisons our food supply. As a result, we never know which foods are safe to eat. Human beings can be not live in a poisoned environment.

Therefore, pollution is a major threat to our existence.

Humans need temperature to be in a comfortable range. To be in a comfortable range means to be neither too hot nor too cold. With global warming, global temperatures are rising. As global temperatures rise, the polar icecaps will melt. As the polar icecaps melt, ocean levels will rise. Areas of some countries will soon be under water. People would be forced to relocated from flooded areas.

In nature, even small changes can sometimes have large effects. It’s difficult to predict what’s going to happen. The entire ecosystem that we depend on is changing. Some of these changings are irreversible. Irreversible changes cannot be undone. Let’s hope the humans are smart enough to understand how the world is changing. With more understanding, we make better choices about what to do. We can face the challenge of the pollutions and global warming. We need to do this bef ore it’s too late. This planet of earth is our only home and we need to protect it.

It’s a new desk. I just brought and now I have to put it together.

Do you need any help?

No, I don’t think so.

I just need to get my tools. I need a screwdriver and maybe a hammer.

Don’t forget to read the instructions.

How were things going?

I’ve almost finished.

Something doesn’t look right to me. The right side is higher than the left side.

Oh, you’re right. It looks like I put a couple of screws into the wrong places.

So now you have to take it apart.

Great, and I thought I was almost finished.

I told you to read the instructions. Did you read them?

No, I didn’t read them. I hate to read the instructions. I looked at them but they were confusing.

Well, this is what happen when you don’t. You were to inpatient. Anyway, what can I do to help you?

Ok, but next time please read the instructions.

Do you ever look up at the sky and think about the lives in the universe?

No, I don’t. in fact, I try not to. When I think about thing too deeply, I get depressed. It’s even a bit frightening.

Really, for me it’s just the opposite. Everything seems like a wonderful miracle.

Doesn’t that frighten you a bit? The universe is so large and we are so small.

What I realize is how little we understand. We just need to appreciate our life and not get lost.

Sometimes being lost isn’t so bad. You know the expression, ignorance is bliss.

Sure, I’ve heard it many times. To be ignorance is to be happy.

Maybe it’s true. Maybe it’s best not to think or know too much.

Not, that’s not for me. I want to understand as much as possible. That’s why I became a scientist.

Well, I respect your choice but it’s not for me. If understanding is painful, I’d rather not understand.

Harry is on the business trip. Yesterday he was supposed to fly from San Francisco to Shanghai. However, things didn’t turn out the way they are supposed to. In fact, nothing went the way it was supposed to. Everything went wrong and he didn’t get on his flight. As a result, he stayed in San Francisco. The following is summary what happen.

Yesterday he got up at usual and had breakfast. Everything seemed to be fine and he was looking forward to the trip. He was just about to check out of his hotel when he felt the pain. It was a pain on his lower back. It was a dorm pain at first, not too bad. So he didn’t worry about it and he checked out the hotel. Then he got on a shuttle bus to the airport. About half way to the airport, the pain in his back started to get worse. It was a growing pain and he was beginning to worry. Soon it was difficult for him to sit in his seat. The pain was getting worse. He wanted to lie down. He started to swear and breathe quickly. He was in real pain then. As a scale of 1 to 10, the pain was an 8.

When the bus got to the airport, the bus driver helped him to get off. It was difficult for him to walk but he finally made it to the terminal. Inside the terminal, he went to the men’s bathroom. He went to the toilet but that didn’t help. Instead of improving, his felt dizzy and he threw up. By now, he was wet from all his sweating. He knew he couldn’t get on his flight. He used his phone to call airline. He explained the situation and cancelled his reservation. Then he called 911 for an emergency help. 911 is the emergency number to call for help in the United States.

An ambulance arrived about 10 minutes after he called. By then, he was in so much pain that he could barely walk. Once inside the ambulance, they gave him oxygen to help him

to breathe. But the pain was still terrible. Then they drove to a hospital near the airport. Luckily, the hospital was on his health plan. That means his health insurance is supposed to pay for everything. Medical costs in the United States are very high. When he arrived to the hospital, he was taken to the emergency room. After some tests, a doctor told him he had a kidney stone. It was a very small stone, but it caused a lot of pain. It was passing through a small tube in his body from his kidney to his bladder. The pain will go away once it got to his bladder. Until then he had to get pain medicine to reduce the pain. Harry didn’t have to stay in hospital for very long. With the pain medicine, the pain went away very quickly. He took a taxi back to his hotel and checked in for another night. Then he called the airline and made a reservation for another flight. The flight will leave tomorrow. Until then, he will just rest in his hotel. There may be a good m ovie to watch. So when you’re traveling, please prepare for the emergencies. Make sure you had a medical insurance. You never know when something like this can happen to you. So be prepared.

L6U n i t1-1L i s t e n i n g事故和身体恢复 Harry Beecham works for a hi-tech German company based in the Munich. Last month, he was in an automobile accident. He was on his way to attend an important meeting in New York City. He had just arrived on a flight from London and was taking a taxi into the city. The weather was terrible and the road was icy. He was in a hurry so he asked the taxi driver to get him into the city as soon as possible. The taxi driver agreed and sped up but just as they left the airport, the car was out of control. It spun around and skidded into(滑入) the path of an oncoming truck. Fortunately, the truck was going too fast, so nobody was killed. But the taxi was severely damaged and both passengers were injured. The taxi driver survived with only a few injured because he was wearing a seatbelt. The car accident wouldn’t have been happened had the weather been better. Had he put on his seatbelt, he might not have been injured so badly. Had the weather been better, the accident wouldn’t have been happened. The taxi airbag had also been deployed(使展开), absorbing much of the impact. However, Harry, who was in the back seat, having put on his seatbelt. As a result, he was severely injured, and had to be rushed to the hospital. Now, a month later, Harry still can’t remember much of what happened. When he first woke up in the hospital, it was several hours after the accident and he wasn’t sure where he was. The bad news was that he couldn’t move his legs. This was because his back had been broken in the accident. The doctor later told him that he might never regain the use of his legs. Some of his nerves in his spine(脊柱) and legs had been damaged but everything else was OK. Now, Harry is trying to figure out what to do. If he works hard and exercises every day, there will still a chance that he legs will recover on their own. There are also some new treatments that might help his nerve regenerate. Still, he should be prepared for the long recovery and possibility that he might never walk again. Without the use of his legs, he wouldn’t be able to continue working in the same way. it wouldn’t be possible to travel, so he would have to find another way to attend the meeting. Either that or he would have to look for another way to make a living. Harry has a good disability insurance, so mon ey won’t be problem for a while. But sooner or later, he wants to be able to earns a living again. Of course he isn’t planning to give up on his legs. If he works hard, he might still be able to regain the use and learn to walk again. Some of his nerves had been damaged but there was a chance that they were healed. The new drugs being developed might make it possible for the nerves to grow back. Still, he has to face the possibility that nothing will work. Whatever happens, Harry is determined to think posi tively. Even he can’t walk, he can still attend the meeting all over the world. With technology, he could be anywhere and there is much that he can still do. Luckily, he still has to use his arms and hands and his brain is still functioning. With the right attitude, he can find a way forward. There is no reason to despair in or feeling sorry for oneself. That kind of think won’t solve anything. He just hopes that his company or another will get him a chance to prove himself. He could still be a valuable asset for them, come or make.

Unit 3-1 Listening There are many forms of lives on earth, including human beings. Life exists in a variety of conditions. Some forms of live live in the watery environment, like the oceans. Other forms of lives can be found in very dry areas like desserts. However, for any form of live to exist, conditions must be right. When the conditions aren’t right, that form of lives can extinct. To become extinct means to die out completely. Conditions must be right for life to exist. Millions of years ago, there were forms of lives that no longer exist. When condition changed, this form of life died out. One extinction event happened about 250 million years ago. This is the largest extinction event of all time. Many forms of lives become extinct. 96% of all lives in the oceans died out. Most insects also became extinct. This event happened over a period of several million years. The causes of this extinction event are still unknown. Possible causes include largest volcanic eruptions and global warming. Some scientists believe that there were several causes. They believe that a series of events caused the extinctions. Scientists are working for better understand what really happened. In modern times, we human beings face changing conditions. For humans to live, we need clean air and clean water. Pollution is now a growing problem around the world. Pollution poisons the air and water that we depend on. Polluted air makes people sick and afraid to get outside. Polluted water poisons our food supply. As a result, we never know which foods are safe to eat. Human beings can be not live in a poisoned environment. Therefore, pollution is a major threat to our existence. Humans need temperature to be in a comfortable range. To be in a comfortable range means to be neither too hot nor too cold. With global warming, global temperatures are rising. As global temperatures rise, the polar icecaps will melt. As the polar icecaps melt, ocean levels will rise. Areas of some countries will soon be under water. People would be forced to relocated from flooded areas. In nature, even small changes can sometimes have large effects. It’s difficult to predict what’s going to happen. The entire ecosystem that we depend on is changing. Some of these changings are irreversible. Irreversible changes cannot be undone. Let’s hope the humans are smart enough to understand how the world is changing. With more understanding, we make better choices about what to do. We c an face the challenge of the pollutions and global warming. We need to do this before it’s too late. This planet of earth is our only home and we need to protect it. Unit 3-1 vocabulary Lizard 蜥蜴 Mammals are covered by hair or fur, have a backbone and warm-blooded.

英语单词学习方法

英语单词学习方法各位读友大家好，此文档由网络收集而来，欢迎您下载，谢谢 一、分清消极词汇和积极词汇 我们学习英语，能学会所有的因素和发音规则，也有可能掌握所有的语法和规则，但要学会所有的单词是无法做到的。且不说外语学习者。即便把英语作为母语使用的人也难以达到这一目标。其实我们学习汉语也是如此。我相信，没有一个中国人敢说他学会了所有汉字。既然我们学不会所有的单词，那么就要把有限的时间用在学习最有用的词汇上。 如对我们所学的汉字稍作分析，就会发现有的字我们只是认识，但在说话行文中很少运用，但有些字就没有这样的差别，看得懂，听得明，说得出，用的上。前一类字，称为消极或接受性词汇(receptive vocabulary),后一类称为积极或表达性词汇(productive vocabulary)。一

般说来，我们掌握的消极词汇数量远远大于积极词汇。 同样，学习英语单词时也有消极和积极词汇之分。从某种意义上说，学习语言的过程也是一个不断将消极词汇逐步变成积极词汇的过程，不同的学习阶段有不用的要求。目前中学的教学大纲上所规定的词汇基本上都应该作为积极词汇来掌握，但事实上，我们并没有达到这一要求，有相当一部分词仍旧停留在消极词汇。 如果作为消极词汇来说，我们只需要见到或听到某词时能说出词义就行了;而作为积极词汇学习要达到以下几方面要求：1)会读;2)会拼;3)能说出词义;4)能知道该词的语法属性;5)能正确运用该词的搭配;6)能指出该词所传达的感情色彩。很显然关用猜测的方法是达不到上述要求的，先猜后查字典可能就比较有效。 二、什么样的单词该记? 英语单词有几十万。要向全记住显

教你一眼看出英语单词意思的方法

教你一眼看出单词意思的方法请大家想一想，英语是谁发明的？英国人呗！英国人认不认识汉语？不认识！那么英国人在学英语单词的时候需不需要记住单词的汉语意思？不需要，英国人的英语课本里根本就没有汉字，何谈记住单词的汉语意思？那么既然英国人学英语不需要记住(甚至根本就见不到)单词的汉语意思，那么中国人学英语为什么要去记住单词的汉语意思呢？这种做法大家不觉得奇怪吗？ 然而由于中国人学英语时都在背单词的汉语意思，因此大家反而觉不出“背汉字”有什么奇怪的了。其实仔细想一想，这个行为真的很奇怪，奇怪的根源不在于行为本身，而在于中国人普遍不会直接识别英语单词的意思，因而只好靠汉语符号来机械地帮助记忆英语单词的意思，这样去学英语不仅多此一举，而且必然会陷入苦海无边的符号记忆灾难中。 其实英语单词和汉字一样，存在着很多的“偏旁部首”，知道了偏旁部首你就可以根据它们直接来猜测单词的意思，虽不说百分之百猜准，但起码可以猜测个大概，至少在别人告诉过你单词的意思后你可以恍然大悟地领会它，这样就可以大大增强你对英语单词“见字识意”的能力，做到真正认识一个单词，而把它的汉语意思仅做为一般参考。 举几个例子来说吧： 比如单词representative，请别急着告诉我你认识这个单词，其实你不见得“认识”这个单词，你仅是凭着你的记忆力记住了这串英语字母和两个汉字符号“代表”之间的对应关系，这样去学英语你会多费劲？下面我来告诉你这个单词为什么是“代表”的意思。re在英语里是一个偏旁部首，它是“回来”的意思；pre 也是一个偏旁部首，是“向前”的意思；sent也是一个偏旁部首，是“发出去、派出去”的意思；a仅是偏旁部首之间的一个“连接件”，没了它两个辅音字母t就要连在一起了，发音会分不开，会费劲，因此用一个元音字母a隔开一下；tive 也是一个偏旁部首，是“人”的意思。那么这几个偏旁部首连在一起是什么意思呢？re-pre-sent-a-tive，就是“回来-向前-派出去-的人”，即“回来征求大家的意见后又被派出去替大家讲话的人”，这不就是“代表”的意思吗！这么去认识一个单词才是真正“认识”了这个单词，把它认识到了骨子里。

Level 6 Unit 1 1/4 Listening Harry bitchem works for a high-tech German company, based in Munich. Last month he was in an automobile accident. He was on his way to attend an important meeting in New York City. 哈里·比特汉姆在慕尼黑的一家德国高科技公司工作。上个月他出了车祸。他正在去纽约参加一个重要会议的路上。 He had just arrived on a flight from London and was taking a taxi into the city. The purpose of his trip was to attend a meeting. The weather was terrible and the road was icy. 他刚从伦敦乘飞机到达，正在打车进城。他这次旅行的目的是参加一个会议。天气很糟糕，道路结冰。 He was in a hurry so he asked the taxi driver to get him into the city as soon as possible. The taxi driver agreed and sped up. But just as they left the airport, the car went out of control. It spun around and skidded into the path of an oncoming truck. Fortunately, the truck wasn’t going too fast, so nobody was killed. But the taxi was severely damaged and both passangers were injured. 他很着急，所以他请出租车司机尽快把他送到城里。出租车司机同意了，加快了速度。但就在他们离开机场时，车失控了。它旋转着滑进一辆迎面而来的卡车的路径。幸运的是，卡车开得不太快，所以没有人死亡。但是出租车严重损坏，两个乘客都受伤了。 The accident wouldn’t have happened had the weather been better. Had the weather been better the accident wouldn’t have happened If the weather hadn’t been bad, the accident probably wouldn’t have happened. The taxi driver survived with only a few injuries because he was wearing a seatbelt. 如果天气好一点，事故就不会发生了。如果天气好一点，事故就不会发生了。如果天气不坏，事故可能不会发生。出租车司机因系安全带而仅受了一点伤，幸免于难。 The taxi’s airbag had also deployed, absorbing much of the impact. However, Harry, who is in the back seat, hadn’t put on his seatbelt. As a result, he was severely injured and had to be rush to a hospital. Had he put on his seatbelt, he might not have been injured so badly. Now a month later Harry still can’t remember much of what happened. When he first woke up in the hospital it was several hours after the accident and he was sure where he was. The bad news was that he couldn’t move his legs. This was because his back had been broken in the accident. The doctors later told him that he might never regain the use of his legs. Some of the nerves in his spain and legs had been damaged but everything else was OK. He couldn’t move his legs because his back had been broken in the accident. 出租车的安全气囊也展开了，吸收了大部分冲击力。然而，坐在后座的哈利没有系上安全带。结果，他受了重伤，不得不赶往医院。如果他系上安全带，他可能不会伤得那么重。一个月后，哈利仍然记不起发生了什么事。当他第一次在医院醒来时，已经是事故发生后的几个小时了，他很确定自己在哪里。坏消息是他的腿动不了。这是因为他的背在事故中折断了。医生后来告诉他，他可能再也不能恢复双腿的功能了。他的西班牙和腿上的一些神经已经受损，但其他一切都没问题。他不能移动他的腿，因为他的背在事故中折断了。 Now Harry is trying to figure out what to do.
