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.

Although many online personality tests are fun, only a few will really give you insight into who you are and what you are supposed to be doing with your life.
At CareerPlanner.com we believe that each individual (个人)，regardless of (不管)race or religion, has a purpose in life, and until you discover what your purpose is, you will not find true happiness, nor true job satisfaction.
This doesn't mean you won't be successful.It just means you won't be happy until you are moving towards your true purpose.
Unfortunately, our school system does very little to help students discover their true career.This is where online personality tests and career tests can help.
Online personality tests and career tests can help you better understand what type of work you should be doing to achieve job satisfaction, happiness, and success.
Personality tests are most useful in giving you insight into “how” your personality compares to others and “how” you like to work.
In particular, if you frequently experience difficulty working with others, or getting their support and cooperation, a really good personality test would show you how to get along better.
While personality tests are very useful at showing you how you like to work and how you like your work environment, they are not really designed to show you “what” type of work is right for you.
That is where Career Interest Tests come in.Online Career Tests, such as the CareerPlann
er.com offers will help you discover what your true interests are, and what type of work you will be passionate about.
