    Gmail tmned five years old this week．It's somewhat amazing to think we've only had it since 2004; Gmail changed the webmail game forever by offering features we now take for granted: a streamlined interface （界面]） , powerful search, pioneering use ofAjax and a then-huge 1 GB of mailbox space．“You'll never need to delete another message " was how Google described it at the time．
    Back then, I was still making do with Hotmail．But its clumsy interface and tiny amount of storage space made the decision to move on an easy one．Getting an account made all the difference in the world to my email experience．Suddenly I was freed from having to delete emails every few days to make space in my mailbox．And the app（application） was smooth and responsive, like a desktop client （客户端程序）—and pretty fast in comparison to Hotmail．" Conversation view" and using labels instead of folders took a little getting used to, but in all Gmail felt far more professional and made me much more productive．
    Gmail is a favorite app of ours ever on WebWorkerDaily, and with good reason．It's still the best webmail client for web workers as it lets us access our email whenever and wherever we need to, on any device, with minimum effort．And Google hasn't spent the five years sitting on its Gmail success, either, but has introduced improvements to the service that include Gmail Tasks, chat, video chat and voice chat, combined with Google Calendar and Docs, Google Apps for Domains, and, of course, even more storage．We've recently covered the many features found in Gmail Labs: a way to "undo" seat messages, using canned responses for smart autoresponders, offline support using Gears and how to customize the way you．view your mailbox using multiple inboxes．
    小题1:The underlined sentence in the first paragraph implies that_____．
    A．we shouldn't take Gmail for granted
    B．you can try to write any kind of message
    C．Gmail can correct your mistakes of itself
    D．you needn't worry about the mailbox space
    小题2:Which of the following is not Gmail's striking feature?
    A．Offline support．B．Using labels．
    C．Undo sent messages．D．Mailbox space．
    小题3:Gmail is _____．
    A．first introduced by WebWorkerDaily
    B．a tool merely used to send messages
    C．a great success just the same as Hotmail
    D．a webmail client with multiple functions
    小题4:What can we infer from the passage?
    A．It is easier and more convenient to use folders．
    B．Quantities of people have chosen to use Gmail．
    C．Gmail had a video chat function when invented．
    D．Gmail and Hotmail were invented at the same time．
    小题5:What is the best title of this passage?
    A．Gmail— favourite app of ours

    Millions of people will be able to track each and every move by friends and family through their mobile phones，thanks to a new feature launched by Google yesterday．
    The new system named “Latitude” uses a map to show exactly where a loved one is at any time, sometimes discovering their location to a few meters．Worried parents will be able to check up on where their children have got to after school, friends can meet for a quick drink if they see they are nearby and wives will be able to see if their husbands really are working late at the office．
    The feature was made available immediately on millions of mobile phones that can access the web，such as the Black Berry．Within weeks Google hopes to launch a new one that will also work on computers as well．
    “Once you've shared your location，you can hide it from all of your friends at once，or you can turn off Google Latitude completely at any time．” said a Google spokesman．“You can adjust your privacy settings in Latitude so that you share as much or as little about your location as you want，with whom you want．”
    Google said that the company had tested the product with thousands of people to make sure that it was safe for the customers，but experts were not so sure．Simon Davies，director of Privacy International，said Latitude would open up a “privacy minefield（危险地带）”．
    “It's about the little white lies．You might be avoiding going to work, and now your boss might be able to see that you're at Twickenham instead of at home．”said Ian Angell, an information expert at the London School of Economics．“You've already got mobile phone technology where husbands and wives track each other in secret．Now Google is so widely used that it will only worsen the situation．”
    60. According to Google，the new system “Latitude” can ___________．
    A．prove that the partner has told a lie about working late
    B．tell the parents the locations of their children after school
    C．provide the friends with the most suitable pub for a drink
    D．help people find what their loved ones are doing at any time
    61. The underlined word “it” in Paragraph 5 probably refers to ___________．
    A．the new system                                      B. the Google company  
    C.  the mobile phone                               D. the privacy minefield
    62. From the passage，we know that Ian Angell believed ___________．
    A．Latitude keeps husbands and wives in good relationship
    B．Google tricked all its customers to make more money
    C．with Latitude more privacy problems would come up
    D．privacy settings could protect your personal information
    63. The best title of the passage might be ___________．
    A．Google Allows You to Track Friends' and Families' Every Move  
    B．Google and BlackBerry Open the New Webs to Their Customers
    C．Latitude Working on Computers is Being Developed by Google
    D．Latitude Sets a Good Example on Mobile Phone Privacy Settings

    D
    　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
    　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
    　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
    　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
    　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
    　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
    　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
    　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
    　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
    　　　A.mean a warming - up im the Arctic
    　　　B.raise the temperature of the earth's surface
    　　　C.prevent the sun's rays from reaching the earth's surface
    　　　D.account for great changes in the climate in the northern hemiphere
    　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
    　　　A.mainly because the levels of carbon dioxide are rising
    　　　B.partly due to variations in the output of solar energy
    　　　C.possibly because the ice caps in the poles are melting
    　　　D.exclusively due to the effect of the inertia of the earth's climate
    　　70.On the basis of their models,scientists are of the opinion that ________.
    　　　A.the climate of the world should be becoming cooler
    　　　B.the new Ice Age will be delayed by the greenhouse effect
    　　　C.the man - made warming effect helps to increase the solar effects
    　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

    D
    Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
    Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
    The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
    Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
    The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
    Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
    68. What is mainly talked about in this passage?
    A. The melting of glaciers.                B. Global warming.
    C. The world’s weather.                  D. The earth’s temperature.
    69. What causes global warming according to scientists?
    A. Human activities.                     B. The nature itself.
    C. The earth’s atmosphere.                D. New discoveries
    70. How can greenhouse gases make the globe warm?
    A. They keep heat in the atmosphere   
    B. They let the heat go out into space.
    C. They release heat into the air.       
    D. They can make the other gases warm.
    71. From the passage we can see that global warming will bring about _________.
    A. the pollution in the atmosphere            B. natural disasters
    C. population pollution                     D. the rise of glaciers

    An important factor that plays a part in susceptibility （易受影响） to colds is age．A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population．Babies are the group suffering most from colds, averaging more than six colds in their first years．Boys have more colds than girls up to age three．After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two．
    The general frequency of colds continues to decline into adults．Elderly people who are in good health have as few as one or two colds annually．One exception is found among people in their twenties, especially women, who show a rise in cold infections（感染）, because people to this age group are most likely to have young children．Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections．
    The study also found that economics （经济状况） plays an important role．As income increases, the frequency at which colds are reported in the family decreases．Families with the lowest income suffer about a third more colds than families at the upper end．Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person．Low income may also influence diet．The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally．
    68. What factors cause people to catch colds easily?
    A. Age and pregnancy．             B. Health and pregnancy．
    C. Health and economics．                  D. Age and economics．
    69. Why does the lowest income lead to the rapid spread of colds?
    A. Because poor people can't afford to go to see a doctor．
    B. Because balanced diet has definitely affected poor people．
    C. Because people with the lowest income have limited living space．
    D. Because cold virus don't have opportunities to travel in poor families．
    70. How does the study prove that age plays a part in susceptibility to colds?
    A. Using comparison．  B. Using graphs．
    C. Using description．  D. Using argument．
    71. What can you learn from the passage?
    A. Families with the lowest income suffer less colds than rich families．
    B. The general frequency of colds are likely to increase among the poor．
    C. Women in their twenties are most likely to avoid cold infections．
    D. The general frequency of colds continue to rise into the adults．

    Computer mouse is no longer so strong. A Canadian engineer has invented a system that enables a computer user to push a cursor（光标）across a screen simply by moving his or her nose .He calls his nose-driven mouse a mouse.
    The inventor ,Dmity Gorodnichy ,came up with the idea for the mouse while building computer software that would help astronauts operate the Canadarm—a long robotic arm on the U.S. space shuttle .His system employs a web-camera that recognizes a computer user’s nose from 25 pixels ,or points of light. Dmity chose the nose because its position remains relatively constant no matter which way the head moves .The system keeps track of the pixels, and the user matches the movements of his or her nose with the progress of the cursor across the screen.
    The mouse keeps track of the eyes too. Two blinks（眨眼）are a “double click,” which turns the mouse on or off.
    The mouse has received mixed comments from those who hold opposite opinions. One called it “a pointless waste of technology” . Another predicted that the nouse will fail to catch on because it makes users “look silly.” Dmity has already adapted the nouse for NousePong, a video game ,and NousePaint ,a drawing program.
    He also predicts that the mouse will attract the people who have suffered from specific disease-pain ,senselessness ,or trembling in the hand caused by the frequent repetition of movements of the wrist and fingers ,such as typing at a computer keyboard .His next plan is to adapt the nouse for use by paralyzed（瘫痪）patients in hospitals .With two blinks of the eyes ,patients could double-click for help.
    72．The best title for this passage is probably      .
    A．Mouse Driven by Nose
    B．Cursor Moved Without fingers
    C.New Computer System for Astronauts
    D．New Type of Mouse for Patients
    73．The nouse is a system working by means of          .
    A．keeping track of the points of light
    B．moving one’s nose or blinking
    C.moving cursor across the screen
    D．matching the user’s nose with eyes
    74．The underlined phrase “catch on” means “       ”.
    A．become popular     B．be used      C.get improved        D．be made
    75．Dmity predicts that the nouse will be more used to help          .
    A．those who have eye trouble
    B．develop a video game and drawing program
    C.those traveling in space

    There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration （集中）of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution.
    Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a “greenhouse effect” - raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
    Another view, less widely held, is that increasing particular matter in the atmosphere is preventing sunlight and lowering the earth’s temperature - a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen though one recent government reports that the greenhouse effect is very possible. Perhaps, if we are lucky enough, the two tendencies will offset（抵消）each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people don’t think about the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worth?
    72. As pointed out at the beginning of the passage, people used to think that air pollution ________.
    A. caused widespread damage in the countryside
    B. affected the entire eastern half of the United States
    C. had damaged effect on health
    D. existed only in urban and industrial areas
    73. As to the greenhouse effect, the author ________.
    A. shares the same view with the scientists
    B. is uncertain of its happening
    C. rejects it as being ungrounded
    D. thinks it will destroy the world soon
    74. It can be concluded from the last paragraph that ________.
    A. lowering the world’s temperature only a few degrees would lead major farming areas to disaster
    B. raising the world’s temperature only a few degrees would not do much harm to life on earth
    C. almost no temperature variations have occurred over the past decade
    D. the world’s temperature will remain constant in the years to come
    75. This passage is mainly about ________.
    A. the greenhouse effect
    B. the burning of coal and oil
    C. the potential effect of air pollution
    D. the likelihood of a new ice age

    Can you imagine a catfish bigger than a boy? There are more than 1，000 kinds of catfish；28 species are found in the United States' lakes and rivers． This huge family has some mighty strange members. Let's meet a few.
    Walking catfish．Nature's feisty little catfish，found in southern Florida，has an extra lung for breathing on dry land. When its swimming hole dries up，the walking catfish waddles on stiff forward fins in search of another lake or stream．If an enemy attacks，the fish flares（展开）its top and front fins and leaps at the attacker to scare it off．
    Armored catfish．This catfish has heavy，bony plates protecting its body. The shell makes the fish difficult to bone. To cook it，throw the fish whole into a fire. When it is done，break it open for eating．Some armored catfish are found in Florida，but the 100-pounders live in South America．
    Rounding out the family of strange catfish are talking catfish，which make growing sound when you pull them from the water；climbing catfish，which move quickly up shore brush in search of food；electric catfish，which can deliver a mild shock；and blind catfish，which settle in the inky blackness of underwater caves．Blind catfish find food through taste buds in their eight whiskers（须）．
    Most catfish have four whiskers on the upper jaw and four on the lower jaw. Sensory holes on these whiskers help the fish smell and taste food even in the muddiest of water．The United States does not have catfish anywhere near the size of those in South America．But in some large U.S，rivers，blue and flathead catties do top 100 pounds．
    Most of the catfish you are likely to catch will be much smaller，about frying pan size．When you catch one，remember that the top fins and the forward fins have poison glands（腺）at their bases. They can give you painful wounds （…）
    63．The purpose of the passage is to___________．
    A．encourage readers to go fishing for catfish
    B．inform readers of the world's largest catfish
    C．describe the unusual characteristics of catfish
    D．explain different ways to catch a variety of catfish
    64．The author talks about the way of cooking an armored catfish to show that
    A．it has heavy and bony plates        B．it's hard to cook and eat
    C．it has too many bones      D．it's poisonous inside
    65．Which is NOT mentioned about catfish in the passage?
    A．Its eating habits．                                    B．Its living conditions． 
    C．Its whiskers．                                 D．Its size
    66．What may be continued in the last paragraph?
    A．The author's love for catfish．     B．Where else to catch a catfish．
    C．The origin of the name “catfish”    D．The safest way to handle catfish
