Today many people say that women have the same chance as men in society. But this was not always so. In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work.
One woman who showed that women should have the same chance was Marie, a scientist. In the 1800s scientists knew that a metal, uranium, gave off radiation. They also knew how much radiation came from his element. But they didn’t know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, But it gave off 4 times as much radiation as usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material.
In 1898 Marie Curie set out to find out this new source of radiation, which she named “radium”. Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, And one morning in 1902 Marie found the source of the radiation.
Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.The scientists of Marie Curie’s day knew .
| A．that uranium gave off radiation |
| B．that radium gave off radiation |

In the past many people thought .
| A．that women must get the same chance as men in education and jobs |
| B．that women should receive much education |
| C．that women should get good jobs |
| D．that women could not do the work well |
Marie Curie proved to people .
| A．that there was a new element uranium |
| B．that there was a new element radium |
| C．that women could do their work as well as men if they were really given the same conditions |
| D．both B and C |
If you’re like most kids, you’ve probably made more than a few paper airplanes in your day. But how many kids can say their paper airplanes have been built life-size and then flown? At least one: 12-year-old Arturo Veldenegro of Tucson, Arizona, who won the Pima Air& Space Museum’s first annual Great Paper Airplane Project Fly-Off in March 2012.
“ The purpose of the competition is to inspire and draw kids’ interest in science and flight,” says Tim Vimmerstedt, director of the museum.
About 150 kids entered the competition. The young designers learned about how airplanes fly and then set to work designing their own planes.
Arturo designed and built his airplane. When hen was finished, he took his plane to the flight area and let it fly, outdistancing the other competitors in all age groups. At last, Arturo’s airplane flew the farthest---more than 75 feet!
As the winner, Arturo got to meet with a team of engineers, which took his design and made a bigger one. The new paper airplane might have been the largest one ever built! Arturo named his large paper airplane Arturo’s Desert Eagle.
Later a helicopter tried to lift the paper airplane over the Arizona desert, but it was unsuccessful. Engineers worked for eight hours to repair it for a second try. This time, the helicopter managed to raise it to 2700 feet and then set the plane free.
Arturo watched as his plane flew through the sky at speeds of up to 98 miles per hour for 10 seconds before falling to pieces.
“I felt happy but sad,” Arturo says, “ It flew really well, but it was sad to see it destroyed.”
But that wasn’t the end of Arturo’s Desert Eagle. The Pima Air & Space Museum collected the pieces of the broken plane and put them on show to inspire other young engineers to reach for the sky. According to the text, the Great Paper Airplane Project Fly-Off competition _______
| A．has been held many times |
| B．can only be entered by kids |
| C．is to choose the largest plane |
| D．is held by a team of designers |

What do we know about the paper airplane Arturo built?
| A．It flew the highest | B．It flew for 20 minutes |
| C．It flew more than 75 feet | D．it took him eight hours to build |
In the end, Arturo’s Desert Eagle ______
| A．was made into a helicopter |
| B．was produced in many places |
| C．was sold to a team of engineers |
| D．was put on show in the museum |
Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.What does the underlined phrase “over-consumption” refer to?
| A．Using too much packaging. |
| B．Recycling too many wastes. |
| C．Making more products than necessary. |
| D．Having more material than is needed. |
The author uses figures in Paragraph 2 to show _______.
| A．the tendency of cutting household waste |
| B．the increase of packaging recycling |
| C．the rapid growth of super markets |
| D．the fact of packaging overuse |
According to the text, recycling ______.
| A．helps control the greenhouse effect |
| B．means burning packaging for energy |
| C．is the solution to gas shortage |
| D．leads to a waste of land |
What can be inferred from Paragraph 4?
| A．Unpackaged products are of bad quality. |
| B．Supermarkets care more about packaging. |
| C．It is improper to judge quality by packaging. |
| D．Other products are better packaged than food. |
What can we learn from the last paragraph?
| A．Fighting wastefulness is difficult. |
| B．Needless material is mostly recycled. |
| C．People like collecting recyclable waste. |
| D．The author is proud of their consumer culture. |
Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print?
Paper was first created about 2,000 years ago, and has been made from silk, cotton, bamboo, and, since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren’t many books, few people learned to read.
Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.
Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD-ROMs or machines such as MP3 players.
Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day? No, I don’t think the Yao Ming poster on my bedroom wall will ever be replaced by a computer two metres high!What does the writer do before he goes to sleep’?
| A．He reads books. | B．He reads newspapers |
| C．He looks through magazines | D．He looks at the posters on the wall. |
When was paper first created?
| A．About 2.000 years ago. | B．In the 19th century. |
| C．About 1.000 years ago. | D．In the 11th century. |
Why were books expensive and rare before the invention of printing?
A. People could not read.
B. People could not write words on paper.
C. People could not find silk, cotton or bamboo.
D People could only produce books one at a time by handWhat happened after books became cheaper?
| A．People didn’t want to buy books. |
| B．Printing was invented in China. |
| C．Knowledge and ideas spread quickly. |
| D．The Internet was introduced to people soon |
What is the writer’s opinion about books and computers’?
| A．People won’t need books any more |
| B．Books won’t be replaced by computers. |
| C．People prefer to find information in books. |
| D．Computers have already replaced books. |
When two Bangs meet
Sheldon Cooper is a scientific genius on the popular American TV show, The Big Bang Theory (《生活大爆炸》). He finally met his match last year: Stephen Hawking.
This is not the first time that the scientist has appeared on TV. He has also been on Star Trek (in 1987) and The Simpsons (in 1989). Each time, he played himself.
Hawking, 71, is perhaps the world’s most famous scientist after Albert Einstein. He has spent his whole life studying the beginning and the end of the universe, including the Big Bang (宇宙大爆炸) theory.
The Big Bang theory explains the early development of the universe. According to the theory, about 13.7 billion years ago everything was all squeezed （挤压）together in a tiny, tight little ball, and then the ball exploded. The results of that explosion are what we call the universe.
Hawking has always tried to make science more popular with people. His book: A Brief History of Time was published in 1988. In the book he shares his understanding of the universe in simple language. The book tries to explain many subjects about the universe to common readers, including the Big Bang, black holes and light cones (光锥).
Hawking’s achievements are even greater if you think about his disability. When he was 21, Hawking caught a bad illness that slowly stopped him from moving or talking. Now he sits on a wheelchair with a computer by his side. To communicate, he moves two fingers to control the computer’s mouse. He chooses his words from the screen, which are then spoken by a voice synthesizer (合成器).
Hawking also believes that there might be aliens in space. However, he believes they are probably very dangerous, so we should not look for them. “I imagine they might exist in very big ships ... having used up all the resources from their home planet,” Hawking said in a British documentary（纪录片） named Into the Universe with Stephen Hawking. What does the “two Bangs” in the title refer to?
| A．The director of “The Big Bang Theory” and the founder of it. |
| B．The director and the actor of “The Big Bang Theory”. |
| C．The founder of the “Big Bang” theory and its spreader. |
| D．The scientific genius on TV show and the one alive in real life. |
Acting in The Big Bang Theory is Hawking’s _____ time on TV.
| A．first | B．second | C．third | D．fourth |
According to Paragraph 5, Hawking wrote the book A Brief History of Time especially for _____.
| A．scientists who study the universe |
| B．people who know a lot about the universe |
| C．people who know little about the universe |
| D．people who only know simple language |
The Big Bang theory mainly explains _____.
| A．how the universe started | B．what the universe is like |
| C．how old the universe is | D．how the universe exploded |
According to the passage, which of the following about Hawking is TRUE?
| A．He was born with a disability. |
| B．He uses a computer to communicate. |
| C．He believes aliens are our friends. |
| D．He encourages people to look for aliens. |
From the beginning of human history, wild animals provided food, clothing and sometimes medicine for man. We may not depend as much on wild animals now. But we hear about them every day. Americans use the names of animals in many ways. Automobile manufacturers and gasoline companies especially like to use big cats to sell their products. They like lions, tigers and wildcats. When Americans say wildcat, they usually mean a lynx, an ocelot or a bobcat. All these cats attack quickly and fiercely. So wildcats represent something fast and fierce.
An early American use of the word wildcat was quite different. It was used to describe members of Congress who declared war on Britain in 1812. A magazine of that year said the wildcat congressmen went home. It said they were unable to face the responsibility of having involved their country in an unnecessary war.
Wildcat also has been used as a name for money in the 1800s. At that time, some states permitted banks to make their own money. One bank in the state of Michigan offered paper money with a picture of a wildcat on it. Some banks, however, did not have enough gold to support all the paper money they offered. So the money had little or no value. It was called a wildcat bill or a wildcat banknote. The banks who offered this money were called wildcat banks. A newspaper of the time said those were the days of wildcat money. It said a man might be rich in the morning and poor by night.
Wildcat then was also used for an oil well or gold mine that had almost no oil or gold in it. Dishonest developers would buy such property. Then they would sell it and leave town with the money. The buyers were left with worthless holes in the ground. Today, wildcat oil wells are in areas that are not known to have oil.What is the main idea of the passage?
| A．Wildcats and their stories. |
| B．Wildcats and their characters. |
| C．Varieties of animal species. |
| D．Relationship between animals and humans. |
The underlined words "a lynx, an ocelot or a bobcat" in Paragraph 1 may refer to "__________".
| A．gasoline companies | B．automobile manufacturers |
| C．brands of automobile | D．names of wildcats |
Which of the following would people like to have or trust according to the passage?
| A．Wildcat congressmen. | B．Wildcat oil wells. |
| C．Wildcat banks. | D．Wildcat cars. |
It can be inferred that during the days of wildcat money__________.
| A．people couldn't buy anything with the money |
| B．people complained and suffered a lot |
| C．the rich invested too much on oil wells |
| D．people didn't know how to save money |
