The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.

On 17 July , a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.

Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.

Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?

2．When the first piece hits the South Atlantic, it causes  ________  .

A．an earthquake   B．damages to cities   C．an Earth explosion   D．huge waves

3．Why can’t the northern half of the earth escape for long ?

A．Because the land is covered with water

B．Because the light and heat from the sun can not reach the earth .

C．Because people there can not live at the temperature of zero .

D．Because wars break out among countries .

4．By giving the example of dinosaurs , the author tries to prove ________ .

A．animals could not live in the cold climate

B．what happened 65 million years ago was an invented story

C．the human beings will die out in 2094

Some people bring out the best in you in a way that you might never have fully realized on your own. My mom was one of those people.

My father died when I was nine months old, making my mom a single mother at the age of eighteen. While I was growing up, we lived a very hard life. We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, “Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it.”

At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mother spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again if I wanted to badly enough. She drove that message so deep into my heart that I finally believed her. A year later, I returned to school — walking on my own!

When the Great Depression (大萧条) hit, my mom lost her job. Then I left school to support the both of us. At that moment, I was determined never to be poor again.

Over the years, I experienced various levels of business success. But the real turning point occurred on a vacation I took with my wife and five kids in 1951. I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel (汽车旅馆) for families that would never charge extra for children. There were plenty of doubters at that time.

Not surprisingly, mom was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business, we experienced a lot of challenges. But with my mother’s words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the world — Holiday Inn. In 1979 my company had 1, 759 inns in more than fifty countries with an income of $ 1 billion a year.

You may not have started out life in the best situation. But if you can find a task in life worth working for and believe in yourself, nothing can stop you.
