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.

懂你英语Level4 Unit 3 Part1 it 3-1 listening时间花费 Look at these 2 pie graphs. They show how these 2 people spend their days, not including weekends. The one on the top shows how Emma divides up her days. She is a designer who works for a company. As Emma’s graph shows, the biggest portion部分 of her day is spent working. She works an average of 8 hours a day, which is one third of her day. She gets an average of 6 hours to sleep which is 25% of her day. That’s less sleep than Marti n gets. According to his graph, he gets an average of 7 hours to sleep which is about 29% of his day. On the other hand, Martine who is engineer, works more hours than Emma does. Martine average 9 hours a day at work co mpare to Emma’s 8. That’s 37.5% compare to 33%. Other factors shown in the graph included time for meals and commuting to work. Other activities include getting dress and doing household chores such as doing laundry and paying bills. As you can see, for Martin, commuting is taking a large amount of his time. If he could reduce his commute time, he will have more time for other things. And it isn’t just the time. When the traffic is really heavy his commute is stressful. It will be great if he can work from home one or two days a week. He life will be more enjoyable. And we look at Emma’s graph, we see she probably needs more sleep. Perhaps, she should spend a bit less time socializing with her friends. On the other hand, socializing with her friend is something she really values. As for putting on makeup, she isn’t willing to change that. For her, exercising, socializing and staying beautiful help her deal with the stressful work. In conclusion, Emma and Martin both wish there were more hours in a day. This next graph shows how various factors compare important to 1350 jobs applicants. Applicants were between 20 to 25 years ago. They were asked to list which factors were most important for a good job. As the graph shows, money was the most important factor for 25% of the applicants. However, other factors are also important. The second most important factor was the work environment. In other words, for many, money is everything. People want to like where they work. In fact, if we combine working environment and co-workers, the total is 35%. This is well above the 25% for salary and benefits. Taking together, they are more important than salary and benefits. Career path is also important especially for younger applicants. They want to see that their job helps to build a successful career. For older workers, this may not be as important.

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.
