    Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there 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 might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.

    Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve 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 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it 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, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen (花粉) kept in lake mud. Going back to the last ice age means drilling 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 forest reacts to climate change.

(1)、How do scientists study the past climate change?
A、By predicting the climate change in the future. B、By drilling down deep into land sediments. C、By taking samples from rivers in the Amazon. D、By analyzing fossilized pollen in lake mud.
(2)、What is needed for drilling down into lake sediments?
A、The latest helicopter. B、The special equipment. C、The light machinery. D、The narrow path.
(3)、What is the purpose of writing the passage?
A、To attract more people's attention to CO2. B、To call on people to protect rainforests. C、To inform people of how scientists work on rainforests. D、To warn people to stay away from the danger of rainforests.
(4)、The best title for the text may be_______.
A、Mystery of the Rainforest B、Climates of the Amazon C、The History of the Rainforest D、Changes of the Rainforest

  “I honestly have no idea how that cat got up there. It's a hundred—foot—metal pole. There's no way he climbed that thing,”Jim said to the worried woman. It wasn't even her cat, but she was passing by and saw it. immediately calling the fire—station to come to save it. Jim saw a lotof strange things as a fireman, often sad or upsetting things, but this was new.

  “I suppose we could get the blanket and see if we can convince the poor cat to jump down. But he doesn't really look too scared…”Jim said to the woman.

  “Dave, get overhere!” Jim called over his shoulder to the fire truck driver. Dave walked over and looked where Jim was pointing.

  “How'd he get up there?”

    Jim shrugged, similarly puzzled.“Do you suppose we could get the blanket and convince him tojump?”

    Dave shrugged in response.“I don't seewhy not.”

    Jim looked up at the black mass on the top of the flagpole, the Americannag waving proudly beneath him. It was definitely a cat, and heregarded the people gathered below as if they were his subjects(臣民) and he their king, his yellow eyes scanning his surroundings with apparentd is interest.

    When the blanket was spread out below the cat, Jim and Davebegan striking the flagpole. The cat lookeddown, and then gazed into the sky as if it were looking for something. Jim and Davefollowed his gaze. Suddenly, out of theclear sky, appeared adark figure. The figures wooped(俯冲) low toward the flag pole. It was aneagle! As it got closer, the cat leaped down the pole swiftly onto the ground, and then got lost in the bushes.

    Jim, Dave, and the oldwoman were left with their mouths open. They all agreedit was the best way to get it down.

    Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled-to $1.01 per pack-smokers have jammed telephone "quit lines" across the country seeking to kick the habit.

    This is not a surprise to public health advocates. They've studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase.

    The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely.

    In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drugstore Wednesday. In Charleston, S.C., where the 7-cent-a-pack tax is the lowest in the nation, the price was $4.78.

    The influence is obvious.

    In New York, high school smoking hit a new low in the latest surveys-13.8%, far below the national average. By comparison, 26% of high school students smoke in Kentucky. Other low-tax states have similarly depressing teen-smoking records.

    Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans "who choose to smoke".

    That's true. But there is more reason in keeping future generations of low-income workers from getting hooked in the first place. As for today's adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    Make plans — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

    All of us spend a large part of our lives at home — eating, sleeping, relaxing and communicating with our family members. Our home is a shelter for us, away from the noisy, busy, and polluted world outside — a place where we can let down our hair and dress casually. Eco­friendliness (环保) is a hot word today and we all know we should make our environment as eco­friendly as possible. This is not only good for our health, but also good for the outward environment. Here are some easy and helpful tips to make your home eco­friendly.

    Kitchen

    Plan the kitchen to be bright and airy so that you don't have to turn on the lights at daytime. Don't make wasteful use of the gas. Keep all ingredients for cooking ready before lighting the gas. Turn it to low when not required — always using it on "high" burns a lot of gas.

    Indoor plants

    Plants are extremely eco­friendly and can be used to make your home look lively. Apart from adding life to home, they give out O2, thus making the air inside fresh. You can keep plants in your home, but be sure to show them some sunlight regularly. Also, if they are kept outside, clean their leaves with a wet cloth, as dust may be added to them. A home decorated (装饰) with plants looks attractive. Plants are a natural home decorating gift that shows concern about the environment. A green plant is a wonderful gift which will protect the earth and is sure to be appreciated.

    Saving water

    Most of the time, we take water for granted — we keep water running while brushing our teeth or washing clothes. Needless to say, this is a huge waste of natural resources (资源). Try to recycle water. For example, the water used for washing vegetables can be used for watering plants; the soapy water used for washing clothes can be used to clean the bathroom and kitchen.

Facial expressions carry meaning that is determined by situations and relationships. For example, in American culture the smile is in general an expression of pleasure. Yet it also has other uses. A woman's smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile may show love or politeness. It can also hide true feelings. It often causes confusion across cultures. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places (although this is less common in big cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don't smile enough. In Southeast Asian cultures, a smile is frequently used to cover painful feelings. Vietnamese people may tell a sad story but end the story with a smile.

Our faces show emotions, but we should not attempt to "read" people from another culture as we would "read" someone from our own culture. The fact that members of one culture do not express their emotions as openly as members of another culture, but it does not mean that they do not experience emotions. Rather, there are cultural differences in the amount of facial expressiveness permitted. For example, in public and in formal situations many Japanese do not show their emotions as freely as Americans do. When with friends, Japanese and Americans seem to show their emotions similarly.

It is difficult to conclude about Americans and facial expressiveness because of personal and cultural differences in the United States. People from certain cultural backgrounds in the United States seem to be more facially expressive than others. The key is to try not to judge people whose ways of showing emotion are different. If we judge according to our own cultural habits, we may make the mistake of "reading" the other person incorrectly.
