Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices． The action follows recent reports about the storing of information on the Apple iPhone． Some people consider location tracking to be a threat to personal privacy and security．
Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks． This information is usually stored by the companies, not the devices, and there are laws to protect it． Law enforcement（執(zhí)法） agencies, for example, have to have a fairly high standard before it can access that data． And the phone company is also prohibited from selling that information．
Now, two researchers report that location tracking information is being stored directly on Apple devices． They said Apple’s newest operating systems gather global positioning system and timestamp information． The information is stored on the device in a file that is also uploaded （上傳） to any computer that the device is connected to． The researchers say the information is available to anyone who has access to the device or computer．
Allan Friedman says, “This raises additional concerns． There’s the idea that because it’s on my phone and on my computer, rogue applications（惡意程序） that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it．”
Apple says it is “not tracking the location of your iPhone”． It is simply keeping a database of Wi-Fi hotspots and cellphone towers near the user’s location． This information is meant to help the iPhone quickly find its location when needed．
Letters have been sent to some of the leading mobile device developers, including Apple and Google． The letters asked for more information about their location tracking systems． Allan Friedman calls this an important start to strengthening privacy laws． He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it． And perhaps the most important question is, is my location data with other facts about me?”
小題1:Why did American lawmakers investigate the use of location-tracking systems on cell-phones?
A．Because the systems can store users’ information
B．Because many users have suffered loss after using them．
C．Because it is thought to threaten users’ privacy．
D．Because many reporters have shown the problem of the systems．
小題2: Allan Friedman believes that ________．
A．wireless companies focus on personal privacy．
B．people are forbidden to get access to private data at will
C．phone companies may sell private information secretly
D．customers may ask wireless companies to locate their tracking
小題3: What do we know from Paragraph 3?
A． Location tracking information is stored online．
B．Apple’s newest operating systems collect all kinds of information．
C．Location tracking information may be uploaded to any iPhone．
D．Apple’s newest operating systems may reveal the private information of users．

Ever wondered how one person could save the planet from the effects of climate change?
A British-made computer game on trial release on Monday creates different ways of doing just that．
“Fate of the World”puts the Earth’s future in players’ hands, placing them in charge of an international environmental body which could save the world from the effects of rising greenhouse gas emissions（排放）or let it destroyed by more emissions．
Through different scenes, players can explore options such as geoengineering（地球工程） and alternative energy sources to save the planet from rising temperatures, decreasing natural resources and a growing population over the next 200 years．
An improved version of the game will be followed by a three-month feedback period from players, with final release due in February next year．
Created by Oxford-based games developer Red Redemption, the game is different from other mainstream action games mainly by using data from real climate models and advice from scientists and economists．
“Science data is often inaccessible and we are trying to put players in a position of power and connected with the issues,” Gobion Rowlands, Red Redemption’s founder and chairman said．
This year, a series of apparent errors in climate science and the failure of UN talks to reach an international deal to cut greenhouse gas emissions appeared to weaken the public’s interest in climate change．
However, games centered on sustainability（持續(xù)性）and human rights have been growing in popularity and are welcomed by green groups as a way of raising awareness．
Using climate change as inspiration for entertainment shows the issue has affected global culture, which can only be a good thing．Friends of the Earth’s head of climate Mike Childs said.“We need creative industries to work with these big issues as the results can be extremely powerful and can help us to understand what a sustainable future looks and feels like,”he added．
小題1:“Fate of the World” in the passage refers to                      ．
A．a(chǎn) book on computer gamesB．a(chǎn) company developing computer games
C．a(chǎn) computer game on climate changeD．a(chǎn) player in charge of computer games
小題2:What makes the climate computer game different from the other games?
A．It uses data from real climate models and advice from experts．
B．It is the only computer game about climate．
C．It can save the planet from the effect of climate change．
D．It aims to affect the global culture．
小題3:It can be concluded from the passage that                        ．
A．games on sustainability and human rights are very popular among young players
B．the game increases players’ awareness of environmental protection
C．only computer experts can play the new climate computer game
D．a(chǎn)fter a three-month feedback period from players, the new game is on sale now
小題4:Which of the following can NOT the players experience while playing the new game?
A．Challenging the climate change in an unreal world
B．Understanding what a sustainable future looks and feels like
C．Enjoying the power to decide the earth’s fate
D．Predicting what will happen in 200 years
小題5:In which column of a newspaper can you probably read this article?

When you’re surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?
According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters- to record the computer user’s age, gender, location, favorite movies and hobbies.
The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated(高科技) software called a "beacon" to capture what people are typing on a website.
Lotame packages that data into profiles（個人資料）about individuals, only without their names, and sells the profiles to companies seeking customers．Batches of such data may be sold for a few dollars.
The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web.
The "cookie"- a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news．There are new and more complex tools such as "beacons" which scan in real time what people are doing on a webpage．These beacons instantly assess the Internet user’s location, income, shopping interests and even medical conditions.
Millions of Internet users around the world also face unprecedented（空前的）threats．Private, sensitive, personal and business information is being gathered and sold without their knowledge.
Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don’t know that they were installing intrusive files on visitors’ computers．These include MSN.com and Yahoo.com.
Next time you visit a webpage and find an ad banner advertising something you’ve been planning to buy, don’t be amazed that your computer can read your mind.
小題1:The purpose of the passage is to          .
A．introduce a tiny file in a computer-a single code

In today's world of cell phones, mini laptops and MP3 players, most people have at least one time-telling tool with them. Since these devices are so common, is time running out for the 500-year-old watch? According to some consumers, yes. New Jersey teenager Charlie Wollman says a watch is "an extra piece of equipment with no necessary function." Many young adults agree ─ and use their cell phones to tell time. Louis Galie, a senior vice president at Timex, said that fewer young people wear watches today than five years ago. As a result, some people claim that the watch industry is at a crossroads.
However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality timepiece that doesn't just keep good time. Fifty years ago, watchmakers boasted(自夸) about their products' accuracy. But in recent years, the watch industry has transformed itself into an accessory(附件，配件) business. And for many today, the image(外形) a watch communicates has become more important than the time it tells.
"Complications" ─ features that go beyond simple timekeeping ─ are an important part of a watch's image. Today's watches offer a host of features that suit almost any personality. These features include altitude trackers(追蹤器), compasses(指南針), lunar calendars, USB drives, and even devices that measure the effectiveness of golf swings!
Creativity is also a key element in today's watches. For example, Japanese watchmaker Tokyoflash makes watches that don't even look like watches. The company's popular Shinshoku model uses different color lights to tell the time. It looks more like a futuristic bracelet(手鐲) than a watch. Another Japanese watchmaker, EleeNo, makes a "handless" watch. Using a ring of circles to keep time, this watch makes an excellent conversation piece.
Whether a watch communicates fashion sense, creative flair or a love of sports, consumers want their timepieces to stand out. Nowadays, everyone has the same kind of gadget in their bags, so people want to make a statement with what's on their wrists(手腕). Will this interest in wrist fashion last? Only time will tell!
小題1:Why aren’t watches popular with young people as before?
A．Because watches cannot keep good time as cell phones, mini laptops and MP3 players.
B．Because watches are featured by the disadvantages of simple function
C．Because watches are too expensive to afford.
D．Because watches don’t have beautiful appearance as other modern time telling tools.
小題2: What does the underlined sentence in Paragraph 1 mean?
A．Watching-making is facing a survival crisis challenge.
B．Watching-making is faced with the developing opportunity.
C．Watching-making becomes the sun rising industry.
D．Watching-making has a specific development target.
小題3: It can be implied that ____________________.
A．people will gradually lose interest in watches as they grow older
B．watchmakers hardly change the development strategy for watches
C．today’s watches are better than those in the past in quality
D．customers used to be more concerned with the quality of a watch than with its image.
小題4:The following qualities can make a watch popular EXCEPT _________.
A．multifunctionB．a(chǎn)ccuracyC．nice designD．low price
小題5:What’s the best title of the passage?
A．Watches and TeenagersB．The History of Watches
C．The Accuracy of WatchesD．Watches Tell More Than Time

When Xia Min started drinking alcohol with her classmates at a friend’s birthday, she didn’t realize what would happen to her. She drank a lot and fell into a coma (昏迷). The 15year-old girl from Chongqing never recovered.
Xia’s death is warning to other students. A new rule went into effect on January 1, 2006. Teens are not allowed to buy or drink alcohol. Shops are not allowed to sell it to them.

After a very busy afternoon, as I walked into my house, I heard the phone ringing. It was my friend Lydia, upset over an argument with her husband. My usual approach is to offer advice, but this time, extremely tired from chores, I simply pulled off my coat, sat down in a chair and listened to my friend's frustration and sadness. Without the disturbance of judgment or the desire to comfort her, I stayed totally quiet while she talked. Eventually Lydia's depression eased and we said our goodbyes. The next day she phoned to thank me. "I'm so grateful for the way you helped me through this," she said.
At first I was surprised. After all, I had done nothing except be there for her. But after I had my own venting(發(fā)泄的) experience with another friend later that evening, I realized that my focused silence had some value. In fact, most relationship experts agree that talk is cheap; it's listening that's rare and valuable. It allows you not only to hear what the other person is saying, but also to have a clear understanding of her thoughts and feelings. And for the speaker, that level of understanding translates into concern and respect.
Unfortunately, listening isn't as easy as it sounds. Thanks to schedules filled with family and work, multitasking has become the barrier(障礙) to listening. My tiredness may have been the only thing stopping me from folding laundry or checking my e-mail while Lydia talked that afternoon.
Another barrier to listening is our listening system: Most of us take in only about half of what's being said during a conversation, according to the International Listening Association. Research shows that we speak at 125 to 150 words per minute, yet think at 500 words a minute. Therefore, because we think much more quickly than we speak, it is easy for us to lose our concentration when listening to speakers.
While it can be hard to focus at times, it's a skill worth developing. With a little practice — employing some techniques— you can become a better listener.
小題1: In Paragraph 2, the author mainly talks about ____.
A．the importance of listeningB．the importance of venting anger
C．her own listening experienceD．her own venting experience
小題2:The author uses the result of the research in Paragraph 4 to mainly show that ____.
A．we think much more quickly than we speak
B．we can only understand about half of what we hear
C．there is not much thinking time available while we are listening
D．we lose our concentration easily while we are listening
小題3: What will be discussed following the passage?
A．Why listening is valuable.B．What we should do while listening
C．How to become a good listenerD．How to stop drifting off while listening.

US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.
The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado.
“This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.
“The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”
Analysis of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤積) sediment (沉積) which formed a delta (三角洲).
“Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.
Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.
The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study.
Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.
小題1:The size of the lake found on Mars is ______.
A．80 square miles B．1,500 square miles
C．3.4 billion square milesD．300 million square miles
小題2:When the lake existed, the weather on Mars was ____.
A．hot and wet B．wet and warm C．cold and dryD．cold and wet
小題3:Why do scientists think deltas near the lake may hold secrets about past life on Mars?
A．Because similar places on Earth have become natural deposits of markers of life.
B．Because someone has put secrets about past life on Mars there.
C．Because past life has been found in other deltas on Mars.
D．Because some people are said to have already seen life marks there.
小題4:Which of the following statements is NOT true according to the passage?
A．The Noachan epoch was a wet and warm era.
B．The lake might have existed 3.4 billion years.
C．The discovery can’ t fully prove that the Mars once hosted life.
D．The lake traces prove that there exists life on Mars now.
