Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更換）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.
The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."
Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.
At present , the U.S. has no federal law for the disposal (處理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (過(guò)濾) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."
小題1:Which of the following is most likely not to be a form of e-waste?
A．A mobile phoneB．A radio C．An e-bikeD．A table
小題2:What does the underlined word "retrieve" (paragraph 2) probably mean?

While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(發(fā)射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies. USA

My dream ended when I was born. Although I never knew it then, I just held on to something that would never come to pass. Dreams really do exist. But in the morning when you wake up, they are remembered just as a dream. That is what happened to me.
I always had the dream to dance like a beautiful ballerina（芭蕾舞女演員）turning around and around and hearing people applaud for me. When I was young, I would turn around and around in the fields of wildflowers that grew in my backyard. 
Reality woke me up when I heard someone saying, "I don't know why you bother trying to dance. Ballerinas are pretty and slender(苗條) girls. Besides, you don't have the talent to even be a ballerina." I remember how those words hurt every feeling in my body. I fell to the ground and wept for hours. 
I enjoyed hanging out by the water. I would sit there for hours and stare at my reflection(倒影). There I was, looking nothing like a pretty ballerina dancer. Reflections don't lie. Once the waves would come, my reflection was washed away just like my dream to dance.
As I grew older, I began to realize that the reason my dream was even born was because it was something that was inside of me. The dream I had was never nurtured(培育) and cared for, so it slowly died. It's not that I wanted it to die, but I allowed it to die the day I started listening to the words, "You can't do it." When I finally woke up from many years of dreaming, I realized that you can't only settle for dancing in the wildflowers, you have to move on to the platform.

A study of English learning problems was carried out among a total of 106 foreign students. It shows that most students considered understanding spoken English to be their biggest problem on arrival. This was followed by speaking. Writing increased as a problem as students discovered difficulties in writing papers that they were now expected to hand in. Reading remained as a significant(顯著的) problem.  
The information gained helped us in determining where special attention should be paid in our course. Although many students have chosen to join the course with a reasonable motivation(動(dòng)機(jī)), we considered it important to note what seemed to encourage interest. Nearly all the students have experienced some kind of grammar-based English teaching in their own country. To use the same method would be self-defeating because it might reduce motivation, especially if it has failed in the past. Therefore a different method may help because it is different.
Variety of activity was also seen as a way of maintaining(保持) or increasing motivation. Several years ago we had one timetable that operated throughout, but we soon found that both the students and the teachers lost interest by about halfway through the ten weeks. This led us to a major re-think, so finally we brought it into line with the expressed language needs of the students.
小題1:What is the text mainly about?
A．Foreign students have more problems.
B．There are many ways to improve English.
C．Teaching should meet students’ needs.
D．English learning problems should be studied again.
小題2:Writing became a bigger problem when foreign students________.
A．had to write their papers
B．became better at speaking
C．became less interested in reading
D．had fewer problems with listening
小題3:We may infer from the last two paragraphs that ________.
A．different teaching methods should be used
B．grammar-based teaching seems to be encouraging
C．English courses are necessary for foreign students
D．teaching content should be changed halfway.

The legal age for drinking alcohol in the United States is twenty-one. Underage drinking is a crime but also a common part of college social life. This week in our Foreign Student Series, we look at alcohol rules at American colleges and universities. These rules differ from school to school, as do measures. But many schools have been moving to strengthen their rules.
The United States has more than 17000,000 students in higher education. Each year, 1700 of them die from alcohol-related road crashes and other injuries. 600,000 more are injured while under the influence of alcohol. And almost 700,000 are attacked by another drunken.
One behavior that college officials are trying to prevent is too much drinking. Some researchers have found that students who think binge drinking is normal often think extremely how much other students really drink. A person can die of alcohol poisoning. At Oklahoma University, a nineteen-year-old student died from drinking heavily at a party in 2005
Now alcohol is banned from all sorority houses and university housing. Student organizations can serve alcohol at events but only on Friday and Saturday nights. Other new requirements include an alcohol education program that first-year students take online.
The rules govern behavior on campus (校園) and off. With a first violation(違犯), students pay seventy-five dollars and their parents are told. They must also take an alcohol education class. For a second "strike," they have to pay one hundred fifty dollars. A third strike means that they have to be suspended school for at least one semester.
Since 2005, 363 students have had a first strike. 30 have had a second strike -- and only one hasn’t allowed to go to school for one semester. The president at Oklahoma tells us the aim is not just to punish but to change behavior and the culture at the university.
小題1:The first paragraph mainly tells us that_________.
A．the legal age at the lowest for drinking alcohol is 21
B．many colleges consider drinking alcohol to be a crime
C．drinking alcohol is a necessary and popular campus culture
D．American colleges and universities have their own alcohol rules
小題2:Every year the number of the students who die or are injured because of alcohol in the USA added up to about _______.
A．17000,000B．1,301,700 C．601,700D．1300,000
小題3:If a student has a third strike, he/she should________.
A．have to stop going to school for a timeB．be removed to another school
C．be locked at home for a period D．be forced to leave school forever
小題4:Which of the following statements is supported by the passage ?
A．College students are not allowed to drink alcohol at any time..
B．If students take an alcohol program online, they can drink alcohol .
C．Students having a first strike only receive punishment of fine
D．Students with a second strike pay twice as much as students with a first strike
小題5:We can infer ________from the last two paragraphs.
A．a(chǎn)lcohol rules have no effect on college students
B．drinking alcohol remains a serious problem
C．a(chǎn)lcohol rules aim to change behavior and the culture at the university.
D．the number of students drinking alcohol is dropping in one way.

Have you ever thought, “I wish I could take a year off and just travel around the world”? Well, three lucky American teenagers were able to do just that. The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.
This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (贊助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions. They realized that each of them can make a difference.

Washoe, a female chimpanzee (黑猩猩) believed to be the first non-human to acquire human language, has died of natural causes at the research institute where she was kept.The chimp died on Tuesday night, according to Roger and Deborah Fouts, co-founders of The Chimpanzee and Human Communications Institute in Washington, where she lived.
Washoe was born in 1965 in Africa, where she was captured by the Air Force and taken to the US for research use in the space program. In 1966, she left the program and began living with two scientists, Allen and Beatrix Gardner, who led a project to teach the chimp American Sign Language (ASL) in Washoe, Nevada, for which it was named. Washoe had been living on Central Washington University’s Ellensburg Campus since 1980. She had a vocabulary of about 250 words. Also, Washoe taught sign language to three younger chimps: Tatu, 31, Loulis, 29, and Dar, 31
Primate (靈長(zhǎng)類(lèi)) researcher Jane Goodall, in Fouts’ book Next of Kin, noted the importance of the work with Washoe. “Roger, through his ongoing conversations with Washoe and her extended family, has opened a window into a chimpanzee’s mind,” Goodall said.
Though previous efforts to teach chimps spoken languages had failed, the researchers believed there was a better chance using signs. But Washoe’s language skills were disputed by scientists who believed that language is unique to humans. Among those who doubted that chimps could use language were linguist (語(yǔ)言學(xué)家) Noam Chomsky and Harvard scientist Steven Pinker. They believed primates simply learn to perform certain acts in order to receive rewards, and do not acquire true language. 
小題1:As for its first task, Washoe was involved with _______.
A．some space research
B．a(chǎn) study on African animals
C．a(chǎn)n ASL project
D．the program of training the Air Force
小題2:In Goodall’s opinion, teaching Washoe ASL ______.
A．was not successful
B．led to the book Next of Kin
C．won honor for Fouts
D．made a difference
小題3:In the last paragraph, the underlined word “disputed” probably means “______”.
A．supported
B．studied
C．questioned
D．discussed
小題4:What can be inferred from the passage?
A．The ASL project was first set up in Africa for the study on Washoe.
B．Washoe may communicate with other chimps by signing.
C．Washoe must have been able to speak 250 words or so.
D．The researchers will prove that most chimps could use language.
小題5:Which of the following is TRUE according to the passage?
A．Washoe was the first animal to be taught human language.
B．Washoe, the chimp, was named in honor of a place.
C．There were four chimps in total at Ellensburg Campus.
D．Chomsky believed primates only perform silent signs.

You might think that “global warming” means nothing more than a rise in the world’s temperature But rising sea levels caused by it have resulted in the first evacuation（撤離）of an island nation—the citizens of Tuvalu will have to leave their homeland.
During the 20th century ,sea level rose 8—12 inches. As a result .Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.
Paani Laupepa , a Tuvaluan government official ,reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years .Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions（導(dǎo)致溫室效應(yīng)的氣體排放）,which are a main cause of global warming . “By refusing to sign the agreement ,the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries .
Tuvalu is not the only country that is vulnerable （易受影響的）to rising sea levels .Maumoon Gayoon ,president of the Maldives ,told the United Nations that global warming has made his country of 311,000 an “endangered nation”.
1．The text is mainly about           .
A．rapid changes in earth’s temperature  B．bad effects of global warming
C．moving of a country to a new place       D．reasons for lowland flooding
2．According to scientists ,the DIRECT cause of more and fiercer storms is           .
A．greenhouse gas emissions in industrialized nations
B．higher surface water temperatures of the sea
C．continuous global warming                  
D．rising sea levels
3．Laupepa was not satisfied with the United States because it did not        .
A．a(chǎn)gree to reduce its greenhouse gas emissions
B．sign an agreement with Tuvalu
C．a(chǎn)llow Tuvaluans to move to the US
D．believe the problems facing Tuvalu were real

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃．Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate．Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world．
In the past hundred years，humans have begun destroying rainforests in search of three major resources(資源): land for crops，wood for paper and other products，land for raising farm animals．This action affects the environment as a whole．For example，a lot of carbon dioxide(二氧化碳) in the air comes from burning the rainforests．People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this．Firstly，when people cut down trees，generally they can only use the land for a year or two．Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply．
Rainforests are often called the world’s drug store．More than 25％ of the medicines we use today come from plants in rainforests．However，fewer than l％of rainforest plants have been examined for their medical value．It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests．
小題1:Rainforests can help to adjust the climate because they                ．
A．reflect more heat into the atmosphere
B．bring about high rainfall throughout the world
C．rarely cause the temperature to drop lower than l6℃
D．reduce the effect of heat from the sun on the earth
小題2:What does the word “this” underlined in the third paragraph refer to? 
A．We will lose much more than we can gain．
B．Humans have begun destroying rainforests．
C．People have a strong desire for resources．
D．Much carbon dioxide comes from burning rainforests．
小題3:It can be inferred from the text that      . 
A．we can get enough resources without rainforests
B．there is great medicine potential in rainforests
C．we will grow fewer kinds of crops in the gained land
D．the level of annual rainfall affects wind patterns
小題4:What might be the best title for the text? 
A．How to Save RainforestsB．How to Protect Nature
C．Rainforests and the EnvironmentD．Rainforests and Medical Development
