A weather map is an important tool for geographers.   A succession of three or four maps presents continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts (氣鋒) to determine whether an individual pressure aroa is deepening or becoming shallow and whether a front is increasing or decreasing in intensity (強(qiáng)烈).They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a summary picture of conditions in the atmosphere at a given time.
All students of geography should be able to interpret a weather map accurately.Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States  Weather Bureau issues information about approaching storms, floods, frosts and all climatic conditions in general. Twice a month it issues a 30-day"outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an anaiysis of the upper air levels which often set the stage for development of air masses, fronts and storms.
Considerable effort is being exerted today to achieve more accurate weather
predictions, with identifying and tracking storms over regions which have but few meteorological (氣象)stations. Extensive experiments are also in progress for weathef modification studies.

A student is learning to speak British English. He wonders(想知道): Can I communicate(交際) with Americans? Can they understand me? Learners of English often ask: What are the differences between British and American English? How important are these differences?
Certainly, there are some differences between British and American English. There are a few differences in grammar. For example, speakers of British English say “in hospital” and “Have you a pen?” Americans say “in the hospital” and “Do you have a pen?”.Pronunciation is sometimes different. Americans usually sound theirs in words like “bird” and “hurt”. Speakers of British English do not sound theirs in these words. There are differences between British and American English in spelling and vocabulary. For example, “colour” and “honour” are British, “color” and “honor” are American.
These differences in grammar, pronunciation, spelling and vocabulary are not important, however. For the most part, British and American English are the same language.

LONDON: What could possibly be wrong with planting trees? The benefits are obvious; they  firm the soil, soak up (攝取) extra water and take carbon dioxide (二氧化碳) out of the atmosphere.
However, it now turns out that planting trees could add to global warming.
Tree roots do a great job of keeping soil firmly on the ground and out of the wind’s power. The problem is that some of those dust clouds play an important part in taking in carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface. The dust fuels oceanic life.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting programme there is successful and the dust supply reduced, the final result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work “shows clearly the complexity of the system and the importance of not tinkering(粗劣地修補(bǔ)) with it without understanding the results. For this reason the need is to focus(集中) on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the land surface.”
An American scientist, Robert Jackson, has shown that when native grassland areas are invaded(侵入) by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees, ” says Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed(超過) by the loss of carbon from the soil below ground. Countries that plan to combat global warming by planting trees may have to think again.
Solutions to environmental problems are often more complex than they first appear, and understanding the Earth’s climate is a very great challenge.
小題1:People usually hold the opinion that_____________.
A.huge dust storms can destroy carbon dioxide
B.huge dust storms can destroy the oceans on the earth
C.huge dust storms can’t do anything beneficial for man
D.planting trees is the only way to control huge dust storms
小題2: Andy Ridgwell, the environmental scientist, believes that_____________.
A.dust plays a more important part than trees
B.trees shouldn’t have been planted in dry places
C.carbon dioxide is harmful to everything on the earth
D.environmental problems are more complex than expected
小題3: Robert Jackson’s experiment proves that_____________.
A.grassland areas should be covered by forests
B.trees hold more carbon than grasses
C.carbon can turn grass into dust
D.less carbon can make trees grow faster

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?

Goals can help you do, be and experience everything you want in life. Instead of just letting life happen to you, goals allow you to make your life happen.
Successful and happy people have an idea of how their life should be and they set lots of goals to help them succeed. By setting goals you are taking control of your life. It’s like having a map to show you where you want to go. Think of it this way. There are two drivers. One has a destination in mind which is laid out for her on a map. She can drive straight there without any wasted time or wrong turns. The other driver has no goal or destination or map. She starts off at the same time from the same place as the first driver, but she drives without an aim around, never getting anywhere, just using up gas and oil. Which driver do you want to be?
Winners in life set goals and follow through on them. Winners decide what they want in life and then get there by making plans and setting goals. Unsuccessful people just let life happen by accident. Goals aren’t difficult to set―and they aren’t difficult to reach. It’s up to you to find out what your goals and ideals(理想)really are.
Research tells us that when we write a goal down, we are more likely to achieve. Written goals can be reviewed regularly,and have more power. Like a contract with yourself, they are harder to neglect(忽視)or forget. Also when you write your goals in a particular way, you are able to make yourself be continuously alert(警覺)to situations that will further your goals.
小題1:The writer gave the example of two drivers to show                .
A.how stupid the first driver wasB.the importance of having a map and right direction
C.how stupid the second driver wasD.the importance of setting goals
小題2:According to the passage, successful people are different from unsuccessful ones because   .
A.the successful people set goals for everything and can get help from others
B.the unsuccessful people always set unrealistic plans for themselves
C.the successful people set goals in their lives and make plans to carry it out
D.the unsuccessful people make plans for everything but can not work hard
小題3:According to the passage, the most important thing in realizing one’s ideal is to      .
A.try to be realistic about one’s ability
B.let others help him or her to make his or her dream come true
C.let others understand him or her first,then work together with them
D.have a clear mind of what he or she wants in life
小題4:Which of the following is TRUE according to the passage?
A.Goals can make you gain everything you want in life
B.Only successful people can be happy
C.If you want to succeed,you need a set long-term goals instead of short-term Goals
D.When we put our goal down on papers, we are more likely to succeed
小題5:Which is the best title for the passage?
A.Goals help you succeedB.How to succeed
C.Why we always failedD.A research on setting goals

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.

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

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.

Googlefight is a simple service available on the Internet which offers you the chance to compare two different items and see how many hits they get on the Google search engine. The seemingly simple device has proved invaluable to users, especially to help win arguments.
For example, imagine that you and your friends are arguing about who are the most popular music or movie stars, you can decide the argument by writing the names in the Googlefight boxes. Let’s say that you are arguing about Jackie Chan and Jet Li. You will quickly discover that Jet Li is mentioned 16 million times on Google pages, whereas Jackie Chan is mentioned a mere 12 million times! In this unscientific way, you can claim victory for one Star over another.
But teachers have come up with ways of using Googlefight which are much more useful from an academic point of view, particularly when it comes to studying languages. You can, for example, find out the frequency of two words with the same meaning, and deduce (推斷) from the answers which one is more common. For example, let’s take the words “buy” and “purchase”, which mean the same thing (although “buy” is only a verb and “purchase” is both a verb and a noun). It is immediately clear from Googlefight that “buy” is much more commonly used, with a massive three and a half billion hits, compared to only one billion occurrences for the more formal word.
But the real value of Googlefight to the language learner is in determining which is the more common of two phrases. For example, “raining cats and dogs” is an old-fashioned English expression about the weather. Do English speakers still use it? Or are they more likely to say “pouring down”? Googlefight suggests the latter. “Pouring down” has 898,000 Google hits, whereas “raining cats and dogs” only has 326,000.
With phrases, it’s important to remember that you need to use quote marks to make the search more accurate. For example, if you type in the similar phrases “l(fā)ook after” and “take care of “ without quote marks, the second phrase seems to be more common, but with quote marks, the result is reversed.
小題1:What is Googlefight?
A.A fight between two people on Google.
B.A way to make sure you win an argument.
C.A website showing how many hits two different things have.
D.A list of all the websites on Google.
小題2:Language teachers find it useful because _______.
A.there are a lot of words on Googlefight
B.it can tell them which of the two words with the same meaning appears more often
C.some words mean the same thing
D.common words have a billion hits
小題3:What must you remember to do if you are checking phrases by Googlefight?
A.Make sure they mean be same thing.
B.Make sure they are different.
C.Remember to put quote marks round the phrase.
D.Don’t put quote marks round the phrase.
小題4:Which statement is NOT true according to the passage?
A.Googlefight is effective to determine the more common of two phrases.
B.Googlefight is a scientific way to decide an argument.
C.Quote marks can make the search more accurate.
D.Googlefight is invaluable to help win arguments.
