A big fire break out in a clothing factory in our city the last Wednesday. On 9：18 that morning, when the employees were working busy in the 4-storeyed building, heavy smoke was seeing coming out of the windows on the second floor.

3 . Although problems are a part of our lives, it certainly doesn't mean that we let them rule our lives forever. One day or another, you'll have to stand up and say—problems, I don't want you in my life.

    1    Problems with friends, parents, girlfriends, husbands, and children—the list goes on. Apart from these, the inner conflicts within ourselves work, too. These keep adding to our problems. Problems come in different shaped and colors and feelings.

But good news is that all problems can be dealt with. Now read on to know how to solve your problems.

Talk, it really helps. What most of us think is that our problem can be understood only by us and that no talking is going to help.     2    Talking helps you move on and let go.

Write your problems.     3    When you write down your problems, you are setting free all the tension from your system. You can try throwing away the paper on which you wrote your problems. By doing this, imagine yourself throwing away the problems from your life.

Don't lose faith and hope. No matter what you lose in life, don't lose faith and hope. Even if you lose all your money, family…you should still have faith.     4    

Your problems aren't the worst. No matter what problem you get in life, there are another one million people whose problems are huger than yours.     5    Your problems might just seem big and worse, but in reality they can be removed.

Go about and solve your problems because every problem, however big or small, always has a way out.

4 . 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 analyzing fossilized pollen in lake mud.

D．By taking samples from rivers in the Amazon.

2. Why is it difficult to collect information about the past climate change?

A．Because scientists can't find proper equipment and machinery.

B．Because it is very difficult to obtain complete samples.

C．Because helicopters and aeroplanes have no place to land.

D．Because none of the cores provide any information.

3. Where is the passage most probably taken from?

A．A medical journal.	B．A news report
C．A travel brochure.	D．A science magazine.
