                                这段科技文章看似复杂难懂,其实不难。读的同时不妨仔细分析这类文章的特点,这对
                                于在考试中阅读理解同类文章一定有帮助。
                                For thousands of years humans have wondered how and when the
                                universe first began. Now, thanks to some photographs taken by
                                Wilkinson Microwave Anisotropy Probe (WMAP), scientists are much
                                closer to understanding, even seeing, the universe in its beginning years.
                                This is all possible thanks to the WMAP satellite in orbit about one
                                million miles above Earth. The satellite is specially designed to record
                                one kind of cosmic energy: microwave radiation. It can use this radiation
                                to show us what the universe looked like 13.3 billion years ago! 
                                Wait a minute ... how can this satellite show us a picture of the
                                universe billions of years ago? The Big Bang created the universe in a
                                huge explosion, and at the same time it created a specific field of
                                radiation—called the cosmic microwave background, or CMB. This
                                CMB still lingers in the universe today. What the satellite actually does is
                                take pictures of the CMB. 
                                So what did scientists learn from these new pictures? First, they
                                learned that stars formed very soon— merely 200 million years— after
                                the Big Bang. And they were able to confirm estimates of the universe’s
                                age: it was born about 13.7 billion years ago. This is the age that

                                scientists long suspected to be true, but now they have the birthday
                                pictures to prove it!
