Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
68. What is mainly talked about in this passage?
A. The melting of glaciers.               B. Global warming.
C. The world’s weather.                  D. The earth’s temperature.
69. What causes global warming according to scientists?
A. Human activities.                     B. The nature itself.
C. The earth’s atmosphere.               D. New discoveries
70. How can greenhouse gases make the globe warm?
A. They keep heat in the atmosphere   
B. They let the heat go out into space.
C. They release heat into the air.       
D. They can make the other gases warm.
71. From the passage we can see that global warming will bring about _________.
A. the pollution in the atmosphere            B. natural disasters
C. population pollution                     D. the rise of glaciers

Bertie knew there was something in the wind.His mother had been sad in recent days, not sick, just strangely sad. The lion had just lain down beside him, his head warm on Bertie’s feet when Father cleared his throat and began, “You’ll soon be eight, Bertie. A boy needs a proper education. We’ve found the right place for you, a school near Salisbury in England.”
His heart filled with a terrible fear, all Bertie could think of was his white lion. “But the lion,” he cried, “What about the lion?”
“I’m afraid there’s something else I have to tell you,” his father said. Looking across at Bertie’s mother, he took a deep breath. Then he told Bertie he had met a circus owner from France, who was over in Africa looking for lions to buy. He would come to their farm in a few days.
“No! You can’t send him to a circus!” said Bertie. “People will come to see him. He’ll be shut up behind bars. I promised him he never would be. And they will laugh at him. He’d rather die. Any animal would!” But as he looked across the table at them, he knew their minds were quite made up.
Bertie felt completely betrayed. He waited until he heard his father’s deep breathing next door. With his white lion at his heels, he slipped downstairs, took down his father’s hunting rifle from the rack and stepped out into the night. He ran and ran till his legs could run no more. As the sun came up over the grassland, he climbed to the top of a hill and sat down, his arms round the lion’s neck. The time had come.
“Be wild now,” he whispered. “You’ve got to be wild. Don’t ever come home. All my life I’ll think of you. I promise I will.” He buried his head in the lion’s neck. Then, Bertie clambered down the hill and walked away.
When he looked back, the lion was still sitting there watching him; but then he stood up, yawned, stretched, and sprang down after him. Bertie shouted at him, but he kept coming. He threw sticks. He threw stones. Nothing worked.
There was only one thing left to do. With tears filling his eyes and his mouth, he lifted the rifle to his shoulder and fired over the lion’s head.
Bertie’s mother was sad probably because she ______.

A.had been seriously ill recently
B.had decided to send Bertie to school
C.knew selling the lion would upset Bertie

In the last paragraph, the boy lifted the rifle to ______.

Why buy a new car when you can improve the one you have with the latest technology? Here are two new methods that will not only make life behind wheel more comfortable but may also end up saving you money.

WI-FI on Wheels
It’s not enough that children complain about having nothing to watch on television. These days, they even complain about having nothing to watch in the car. Fortunately, for every unsatisfied youth, there is a new technological solution: Wi-Fi Internet access for the back seat of your vehicle.
In the United States, Chrysler is the first to offer such a system, which turns any Chrysler or Dodge into a Wi-Fi hotspot. Called UConnect, the $499 dealer-installed option is a high-speed cell-like Internet connection with a wireless router that sits in your car’s trunk. Monthly service costs $29 for Internet access, which is available to any device that has Wi-Fi and is within 100 feet of your car.
With UConnect, passengers can check emails messages on a laptop, send instant messages to friends or watch YouTube videos online. It allows passengers to search for movie listings on a smart phone or connect a Sony PSP video game player to the Web. It also offers the ability to freely upload photos from a Wi-Fi-equipped digital camera to an online sharing service like Flickr.
For critics who claim that putting Wi-Fi Internet access in a car feeds the danger of driver distraction, parents may well disagree: What’s more distracting, the temptation to check email or a lot of children talking to you from the back seat?
Watch Your Back
Blind spots behind cars and SUV’s make backing up dangerous as well as potentially deadly for children. Nationally, the group Kids and Cars estimates that two children a week are killed by cars backing up. The Transportation Department is establishing visibility standards for future vehicles, but there’s no need to wait.
A back-view back system can be an expensive option in a new car. In the 2008 Subaru Tribeca, for example, the back-view camera option is available only in connection with the inner navigation system, at a price of $2,400. And professionally equipped systems can cost $400 or more. However, there are now inexpensive back-view packages you can help yourself, such as the $130 Audiovox ACA250 Wireless Vehicle Rear Observation System. It includes a camera that increases on a back license-plate holder and grasps onto a vehicle’s backup light. It can send a back-view image to a small L.C.D. Monitor that can be carried into electronic equipment and increased on the dashboard(仪表板).
Audiovox claims the camera housing is not afraid of dust. In some areas where radio waves are plentiful, the image can be affected by occasional interference, but the picture, with its wide 110-degree camera point, is good enough to see things or children behind you.


What is the best title of the passage?

A.DIY methods for your car.
B.How to save money in your life?
C.The way of putting a back-view system.
D.The importance of putting internet access in your car.

What’s the parents’ attitude to the safety concern of car Internet access?

A.They agree with the critics’ opinion.
B.They consider it a great danger for driving.
C.They think that talking with children is more dangerous.
D.They believe it unnecessary to have car Internet access.

What’s the potential danger for children?

A.Electronic equipment. B.Backing-up car.
C.Earphones behind the wheel. D.Highway engine failure.

How can the back-view package see the back of the car?

A.With a cell phone.
B.With an inner navigation system.
C.With a dashboard.
D.With a camera onto the side of backup light.

Why Doesn’t Anybody Copy Apple?
Apple’s products are the envy of the world. They have been spectacularly successful and are widely imitated, if not copied. The minute Apple crystallizes a product, everyone knows how to compete. This idea that the basis of competition is set by Apple and then the race is on to climb the path of improvement is unquestionable. When Apple releases a product that defines a category or dramatically changes the structure of an industry, it becomes obvious what needs to be built. But what I wonder is why everyone wants to copy Apple’s products but nobody wants to copy being Apple?
I can think of two reasons. Firstly, Apple is not worth copying because it’s not successful; secondly, Apple’s success cannot be copied because it is a magical process.
There is a great deal of evidence for the first hypothesis. The idea of Apple being successful is not something reflected in its stock price. Being valued lower than the average company in the S&P(标准普尔)500 indicates that to whatever degree Apple was successful in the past, it’s not seen by the vast majority of observers as successful in the future. Why should one bother copying Apple if it results in being punished with a low valuation? If one works really hard at innovation and then that innovation becomes commoditized(商品化)very quickly, why should one bother?
When innovation practitioners are asked what makes Apple successful,the answers regarding the cause of this success border on the mythical.The climax of this hypothesis is the “chief-sorcerer”theory of success which places one magician,like Steve Jobs,in charge of casting all the right spells(符咒)
What about Apple’s own opinion of what makes it tick? Tim Cook refers to a great team and integration of hardware, software and services as unique Apple advantages. It’s a better explanation. Integration is something that can take a long time, but it is possible with great effort. A few companies are starting to make moves in that direction, but efforts are half-hearted. There is no “move the Earth” panic to become an integrated company from Samsung, Google or Microsoft.
My own suspicion is that Apple is more aware of what makes it special than it lets out. However, as Tim points out, it’s not a formula. It’s complex, it’s subtle, but it’s not magic. It’s a process that requires a degree of faith and courage.
When a new product of Apple comes out, often it ______.

A.starts a revolution of an industry
B.ruins an industry dramatically
C.puts itself in an unbeatable position
D.is soon overtaken by imitated products

According to the passage, other companies don’t “copy being Apple” because ______.

A.Apple is not a successful company
B.they have no access to relevant resources
C.it’s hard to find a magician like Steve Jobs
D.being Apple takes more than time and efforts

We can infer from Para.5 that ______.

A.other companies are dedicated to integration
B.Apple itself is fully aware of its unique advantages
C.Apple will hold the leading position in this industry
D.other companies don’t have a great team as Apple does

What does the author think of Tim Cook’s statement?

A.Doubtful B.Acceptable
C.Unbelievable D.Disappointing

Chinese writer Mo Yan’s Nobel Prize for Literature might ignite an explosion of global interest in Chinese literature and lead to more titles translated into English, European experts say.
“Hopefully, the award means more people will read Chinese literature and more works will get translated,” says Michel Hocks, professor of the Languages and Cultures of China and Inner Asia from University of London. “Many very good Chinese writers have been accepted globally for a long time already. Mo Yan is probably the most translated Chinese writer alive, with at least five of his novels made available in English over the past 20 years.”
Jonathan Ruppin,web editor of bookseller Foyles,says Mo’s win coincides with growing interest in Chinese literature and recognizes the talents of a distinctive and visionary(富于幻想的)writer.We are very excited by the fact that English translations of more of his books should now become available,”Ruppin says.He made the comment after Mo became the first Chinese citizen to win the Nobel Prize for Literature in it’s century-long history.
As East-West cultural exchange has been booming, Chinese literature has been attracting growing attention in recent years. Hocks explains, “It’s mainly because there are many more opportunities for Chinese writers to visit other countries, to publish their works outside China and to interact with readers abroad. At the same time, more and more people globally are learning Chinese and taking an interest in the Chinese language and culture.”
University of Oxford lecturer in modern Chinese literature Margaret Hillenbrand says, “The obvious reason for the growing global presence of Chinese literature is the growing global presence of China itself. People have come to realize that there is a serious knowledge deficit between China and its international counterparts — in particular, China knows incomparably more about Europe and America than the other way round — and reading Chinese literature is an effective, simple means of solving that gap.”
The underlined word “ignite” in Paragraph 1 probably means “________”.

A.start out B.set off C.burn up D.appeal to

Which of the following is true according to the passage?
