    Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted to the cold, dry climates of the ice ages, but until now, no one has reached a satisfying answer.

    Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier, will it still survive and continue to draw down CO2?

    Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past. Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake mud. Going back to the last ice age means drilling deep down into lake sediments (沉淀物)which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled(未取样).So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.

(1)、What does the underlined phrase “mopping up” in the second paragraph mean?
A、Giving up. B、Giving out. C、Wiping out. D、Taking in.
(2)、How will the Amazon rainforest react to future climate change?
A、It'll get drier and continue to remove CO2. B、There is no exact answer up to present. C、It'll get warmer and then colder and drier. D、It'll remain steamy, warm, damp and thick.
(3)、What's the main idea of the last paragraph?
A、It's important to drill deep down into lake sediments to collect information. B、It's impossible to prove how climate changes in the Amazon rainforest. C、It's hard to collect information for studies of the past climate in the Amazon rainforest. D、It's necessary to have specialized equipment and machinery to study the past climate.
(4)、What is the best title for this passage?
A、Studies of the Rainforests B、Climates of the Amazon C、Secrets of the Ice Age D、Changes of the Rainforests

    With fuel costs rising and airlines finding more fees to impose on travelers every day, airfare isn't getting any cheaper. Since you can't drive to all your dream destinations, flying is the only way to go sometimes and, undeniably, the fastest. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.

    Getting the best fare. Airlines put out their fare sales on Tuesday morning, making this day the best day to book a flight for less.

    Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don't like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues.

    Choose your seat later. Some airlines charge you to pick your seat when you book online, adding even more to the bottom line of your ticket cost. If you show up early on your travel day, you can still get suitable seats. Some of the best seats get held back until flight day, unless others are willing to pay extra for them ahead of time, so you still have the chance at one of those.

    Fly on holidays. You already know that summer is the most expensive time to fly, and even though most other times are more affordable, the days surrounding holidays can be crazy. Save big if you're willing to travel on major holidays, such as Thanksgiving and Christmas.

    Don't wait until the last-minute to book. Many travelers don't know that there's a sweet spot for booking and getting the best price on your tickets. Book too early or too late and you could end up paying more than you need to. The best time to book is between three months and six weeks from when you want to travel.

    Avoiding extra fees Airlines will charge for just about anything these days. Some have even toyed around with charging customers for using the restroom. All those extra fees can certainly add up, but there's no reason to pay them if you don't have to. Here are some tips to keep money in your wallet once you get to the airport.

    Avoid the upgrade it's not necessary. Sometimes upgrades are free, but mostly you will be charged for seeking a last-minute bump to first class, and the cost can be hefty.

    Fly carry-on only. Baggage fees vary wildly, but almost all airlines charge them and charge big. Why pay for your clothes to fly with you? If everyone in your travel party checks a bag, your bill can be astronomical before you ever even get to your destination. It's easy to reduce the amount of stuff you pack: Make sure all your clothing coordinates, so you can take less and still make more outfit combinations, take only two pair of shoes, plan to do a bit of laundry on your trip and bring only travel-sized toiletries.

    Pack your own snacks. Unless you're flying internationally, it's rare your flight comes with a free meal. Snacks on the plane are not cheap and almost never healthy. Don't rely on what's on the small menu and instead tuck some of your own snacks — granola bars, homemade muffins, fruit and trail mix all make fantastic travel foods — into your bag and eat a lot better, and cheaper, than other passengers.

    Do you have a tried and true method of getting the best deal on your flights? Let us know.

    Long bus rides are like television shows.They have a beginning,a middle,and an end with commercials(广告) thrown in every three or four minutes.The commercials are unavoidable.They happen whether you want them or not.Every couple of minutes a billboard glides by outside the bus window.“Buy Super Clean Toothpaste.” “Drink Good Wet Root Beer.” “Fill up with Pacific Gas.” Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of “You Need It!Buy It Now!”

    The beginning of the ride is comfortable and somewhat exciting,even if you've traveled that way before.Usually some things have changed—new houses,new buildings,sometimes even a new road.The bus driver has a style of driving and it's fun to try to figure it out the first hour or so.If the driver is particularly reckless (鲁莽的) or daring,the ride can be as thrilling as a suspense story.Will the driver pass the truck in time?Will the driver move into the right or the left hand lane?After a while,of course,the excitement dies down.Sleeping for a while helps pass the middle hours of the ride.Food always makes bus rides more interesting.But you've got to be careful of what kind of food you eat.Too much salty food can make you very thirsty between stops.

    The end of the ride is somewhat like the beginning.You know it will soon be over and there's a kind of expectation and excitement in that.The seat,of course,has become harder as the hours have passed.By now you've sat with your legs crossed,with your hands in your lap,with your hands on the armrest or even with your hands crossed behind your head.The end comes just at the right time.There are just no more ways to sit.

    November 11 is Veterans Day in the United States. A "veteran" is anyone who has served in the armed forces. The term "veteran" is not just for those who have served in wars. It describes anyone who has ever been in the army.

    On November11, people hold ceremonies(仪式) and parades(游行) to mark Veterans Day. Public officials take part in the events. Army bands play. And soldiers fire guns into the air to remember those who died in service to their country.

    The history of Veterans Day relates to World War I. Many people at the time called it "the war to end all wars." The United States entered the fighting in Europe in 1917. Over 13 million men and women were reported for duty in the army. World War I ended at 11 o'clock in the morning on November 11, 1918. The following year, President Woodrow Wilson signed an official statement to celebrate November 11th as Armistice Day in the United States. It would be a day to honor the men and women who had served in the U.S. armed forces during the war. In 1926, Congress made Armistice Day a national holiday.

    But new problems were on the way. Soon, everyone knew that World War I would not be the war to end all wars. In all, more than 4,000,000 Americans served in the armed forces during the first World War. And 16 million would serve during the second one.

    Armistice Day in 1945 was a special day in the United States. Germany had surrendered in May 1945 and Japan in August. Most men and women who had served in the war were home. So, instead of honoring just veterans of World War I, Americans also honored veterans of World War II. In 1954, Congress decided to change the name of Armistice Day. The holiday became Veterans Day.

    Most people looking for ways to quit smoking worry about weight gain, and with good reason. Smokers who quit tend to pack on an average of 5 pounds after they stop smoking cigarettes. A new study, published by the journal Science, explains why this happens.

    The new research explains that nicotine appears to combine with appetite-regulating neurons (调节食欲的神经元) in the brain, besides the receptors (感受器) that bring about addiction. These neurons help regulate how much food gets consumed, but under the influence of nicotine, they lose their self-control. This is why when smokers quit, they tend to eat more and gain weight.

    The researchers believe that their discovery will lead to the development of drugs that aim at nicotine receptors on brain cells that control appetite. In the future, weight gain may no longer be a reason for smokers to delay the decision to kick the habit, but that's no reason to wait. Nicotine-replacement treatment, while not for everyone, can help. Here are a few more ways to quit smoking and stay slim.

    Drink water. To improve metabolic (新陈代谢的) rates, make half of those glasses ice water. Juice can be too high in calories, something you'll want to keep an eye on your journey toward being a slimmer non-smoker. Plan your snacks. Healthy snacks help keep your metabolism working, so you continue to burn calories while stopping wild hunger pain, or fake hunger.

    Keep moving. Exercise kills two birds with one stone. It helps you burn calories and prevents you from eating when you're not truly hungry. It's also a feel-good stress reliever (缓解物). Focus on your fitness and how being healthy makes you feel. Make exercise a goal and think of quitting as your reward for being physically fit.
