We know the famous ones—the Thomas Edisons and the Alexander Graham Bells —but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper(雨刮器)？Shouldn’t we know who they are?
Joan Mclean think so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she’s developed a course on the topic. In addition to learning “who” invented “what”, however, Mclean also likes her students to learn the answers to the “why” and ”how” questions. According to Mclean,” When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try.”
So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn’t be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever(操作桿)on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.    
Today we benefit from countless inventions and innovations，It’s hard to imagine driving without Garrett A. Morgan’s traffic light. It’s equally impossible to picture a world without Katherine J. Blodgett’s innovation that makes glass invisible, Can you picture life without clear windows and eyeglasses?
小題1:By mentioning “traffic light” and “windshield wiper”, the author indicates that countless inventions are      .
A．beneficial, because their inventors are famous
B．beneficial, though their inventors are less famous
C．not useful, because their inventors are less famous
D．not useful, though their inventors are famous
小題2:Professor Joan McLean’s course aims to_____.
A．a(chǎn)dd colour and variety to students’ campus life
B．inform students of the windshield wiper’s invention
C．carry out the requirements by Mountain University
D．prepare students to try their own invention
小題3:Tommy Lee’s invention of the unbreakable umbrella was _________.
A．not eventually accepted by the umbrella producer
B．inspired by the story behind the windshield wiper
C．due to his dream of being caught in a rainstorm
D．not related to Professor Joan McLean’s lectures
小題4:Which 0f the following can best serve as the title of this passage?
A  How to Help Students to Sell Their Inventions to Producers?
B  How to Design a Built-in Device for Cleaning the Window?
C  Shouldn’t We Know Who Invented the Windshield Wiper?
D  Shouldn’t We Develop Invention Courses in Universities?

Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The “eco-guilt” brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.
Perhaps that explain why a new book by Bjorn Lomborg received so much publicity. That book, The Skeptical Environmentalist, declares that it measures the “real state of the world” as fine. Of course, another explanation is the deep pockets some big businesses with special interests. Indeed, Mr. Lomborg’s views are similar to those of some Industry-funded organizations, which start huge activities though the media to confuse the public about issues like global warming.
So it was strange to see Mr. Lomborg’s book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that “After Lomborg, the environmental movement will begin to die down.”
Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg’s “preference for unexamined materials is incredible (不可信的)”。
A critical (批判的) eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blind before a world partially exhibited by the media. That’s a shame, because matters concerning the health of the planet are far too important to be treated lightly.
小題1: According to the passage, which of the following may be regarded as “skeptics”?
A．People who agree on the popularity of “eco-guilt”.
B．People who disbelieve the serious situation of our planet.
C．People who dislike the harmful effect of human activities.
D．People who spread comforting news to protect our environment.
小題2:Which of the following can be a reason for the popularity of Lomborg’s books?
A．Some big businesses intend to protect their own interests.
B．The book challenges views about the fine state of the world.
C．The author convinces people to seek comforting worldviews.
D．Industry–funded media present confusing information.
小題3:The author mentioned the review in Nature in order to_____.
A．voice a different opinion
B．find fault with Lomborg’s book
C．challenge the authority of the media
D．point out the value of scientific views.
小題4:What is the author’s main purpose in writing the passage?
A．To encourage the skeptics to have a critical eye.
B．To warn the public of the danger of half–blindness with reviews.
C．To blame the media’s lack of responsibility in presenting information.
D．To show the importance of presenting overall information by the media.

I am sure that everybody in his/her life has used computers. Nowadays you can feel their presence everywhere at home，at school，at work and they certainly make life easier．On the other hand，there are people who can’t work with them．
Anyway，I believe their presence is a good thing. Life with them seems easier, less difficult and more comfortable You can use them to choose your meal，to withdraw your money, and also save your time，because these operations are all controlled by computers. Therefore you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．
Nevertheless，problems can often appear in this area, too．To have a computer means you have to be quite well－off and have the necessary skills to use it．However，think about questions like “Are computers so available for everyone, or rich and poor people，for people from villages and people from cities. Aren’t they too expensive？Is everyone able to learn how to use them and not everyone has the chance to access and work with them，how could everything in the future be dependent on them？”Therefore，I think our society will be split into two parts．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out and will actually be far behind the other group．
Another question that bothers me is，on the one hand，computers are important  and good things in our life，but they aren’t everything．They are good as a help at school，quite often as entertainment，especially for young people，as an necessary tool to help in research etc，but I think we shouldn’t be so dependent on them，because computers are only machines and machines can’t feel anything be human and sympathetic，and every action performed by computer can be interfered with another person，which could cause these machines to crash or work badly．
In conclusion，I would like to say I am not against computers．I use computers，too，but people should be wary all the time．
小題1:By saying “wary”（In the last paragraph）,the writer is trying to say “People should_______.
A．be strongly for the use of computers because of its convenience
B．be careful with computers that will also cause problems
C．master more necessary computer skills
D．not do something that causes computers to work badly
小題2:Which of the following best shows the structure of the passage？

小題3: In the third paragraph，the author presents his idea by________
A．a(chǎn)sking questions for people to think about
B．giving examples to support his argument
C．raising questions and answering them
D．expressing his opinion directly
小題4: The writer’s main purpose in writing the passage is__________
A．to encourage us to use computers in our society
B．to advise us to say no to computers from now on
C．to remind us to care about the problems that computers bring.
D．to inform us that the computer has become a necessary part of our life

While reading a book in English, every few lines, you run across a word or two that you don't know. You look up every new word in the dictionary. Bad move. All that does is slow you down. Even electric or CD-ROM dictionaries can get in the way of your reading progress. A dictionary is like a road map. It can help you if you get lost and point you in the right direction. But if you stop to look at the "map" each time you take a step, you'll get nowhere fast.
On your English learning "journey", a dictionary can be a helpful "travel companion"—if it's not overused. To help you start thinking in English, use an English-to-English dictionary. Otherwise, you'll always depend on your native language and end up translating in your head.        
A good dictionary can help you do more than just find the meaning of a word. It can help you verify (test and check) spelling, check word forms and grammar usage, find example sentences and learn pronunciation. Some dictionaries even provide exercises to teach you how to use their resources.
Take time to get to know your dictionary. Learn the pronunciation symbols. Understand what the abbreviations(縮寫字) mean. Become familiar with the grammar codes that explain the usage for each word. Look for charts, diagrams and lists that might be useful in the future. You'll discover how rewarding it can be to make friends with your dictionary. And as they say, "A friend in need is a friend indeed".
小題1: The underlined word "that" used in the last paragraph refers to ________.
A．chart, diagrams and lists
B．a(chǎn)bbreviations and the usage for each word
C．the meaning of a word, spelling and grammar usage
D．pronunciation symbols and grammar codes
小題2:Why do you want to buy a good English-to-English dictionary?
A．Because it is a good friend if we use it often.
B．Because it can help us to find the right direction if we get lost.
C．Because it can help us to start thinking both in English and in Chinese.
D．Without it we'll depend on our native language and end up translating in our head.
小題3:Which of the following statements does the writer lead you to believe? 
A．The more you use a dictionary, the better you can understand the article you read.
B．The more you use the resources in the dictionary, the more you can benefit from it.

Construction workers in Southern California have made a wild discovery. They were digging at a building site in San Timoteo Canyon (峽谷) when they unearthed hundreds of ancient animal fossils. Researchers say the bones hold important clues about the history of the region.
Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents (嚙齒目動物) and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well.
“This is a huge find,” says Rick Greenwood, a scientist studying the site. “I don’t think most people had any idea that those types of animals were wandering around here more than a million years ago.”
San Timoteo Canyon is located about 85 miles from Los Angeles. The area of the canyon where the fossils were found was once part of a green river valley. Today, the region is dry and plant life is rare.
Most of the fossils are well preserved. Experts say a muddy lake bed may have trapped thirty animals that wandered over for a drink. The mud helped to protect the animal fossils.
The remains are a million years older than those discovered at the famous La Brea Tar Pits in Los Angeles. Scientists studying the bones will be able to learn more about how the animals adapted to changes in the environment.
“We have a confused view of what this time period was like, ” says another scientist. “A discovery like this could really be an important contribution.”
About 35 different animal species are represented in the fossil collection. Scientists began removing bones from the site last fall. The project was completed this summer. Starting next year, the fossils will be on display at the Western Science Center in the nearby city of Hemet, California.
小題1:
What does the passage mainly focus on?
A．The secret of ancient animals’ deaths.
B．The preparation for a future fossil exhibition.
C．A great discovery of fossils.
D．The history of San Timoteo Canyon.
小題2:
From what Rick says, we know ________. (原創(chuàng))
A．fossils were discovered in the canyon for the first time.
B．the canyon in ancient times was quite different.
C．more research work will be carried on in the canyon.
D．the river water helped to protect the animal fossils.
小題3:
Compared to the discovery at the La Brea Tar Pits, the canyon-involved fossils _______.
A．a(chǎn)re far olderB．include more species
C．a(chǎn)re better preservedD．make experts more confused
小題4:
What do we know about the fossils from the passage?
A．All of them are of new species.
B．Some of them have been destroyed
C．They were looked for under experts’ guidance.
D．They will be on show in the near future.

We can all contribute to a greener world．Just follow these ten golden rules:
●Stop getting junk mail．Billions of junk mail can be sent every year．Half of it is never opened．Get-your name off mailing lists．If 100,000 people stopped getting junk mail today, it would save 150,000 trees a year．
●Stop reading newspapers．All over the world, millions of newspapers are thrown away every day, 44 million newspapers in the USA alone —that's half a million trees a week．Either recycle your newspapers or read the hews online．
●Buy clothes made from organic materials．Conventional cotton farming seriously pollutes the environment, most of which uses chemical pesticides （農(nóng)藥） and fertilizers． Organic is better!
●Switch to solar energy．In one day, the sun will provide enough energy to power the planet．Why aren't we using it?
●If you have to drive, share the ride．Most cars in the USA have only one occupant．Also, 25 percent of car rides are less than 1．5 kilometres．Get out and walk!
●Unplug your PC, TV and VCR．Simply turning them off isn't enough．Sets left on standby are still using 25 percent of their power．
●Hold on to your balloons．Helium-filled balloons which fly away usually end up in a lake or river, where they can choke aquatic (水生的) creatures．Save your balloons and use them again．Or better still, don't use them at all．
●Feed the birds．Wild birds need food, especially in v/inter when other sources can be scarce．The greater the range of foodstuffs you put out for them, the more types of birds you will attract．
●Plant a garden at your school．Learn the connection between the land and the table．Plant vegetables to eat, flowers to admire and trees to improve the air．
