       But I wonder about my Momma sometimes, and all the other Negro(blacks )mothers who got up at 6 a.m. to go to the white man’s house with sacks over their shoes because it was so wet and cold. I wonder how they made it .They worked very hard for the man, they made his breakfast and they scrubbed his floors and they took care of his babies. They didn’t have too much time for us.

I wonder about my Momma ,who walked out of a white woman’s clean house at midnight and came back to her own where the lights had been out for three months ,and the pipes were frozen and the wind came in through the holes in the wall. She’d have to make deals with the rats: leave some food out for them so the wouldn’t bite the doors or the babies. The roaches（蟑螂）？Oh ,they were just like part of the family!

I wonder how she felt telling those white kids she took care of to brush their teeth after they ate, to wash their hands after they finish bathroom. She could never tell her own kids because there wasn’t soap or water back home.

I wonder how my Momma felt when we came home from school with a list of vitamins and pills the school nurse said we had to have .Momma would cry all night , and then go out and spend most of the rent money for pills. A week later ,the white man would come for his eighteen dollars’ rent and Momma would beg him to wait until tomorrow . She had to lie to him that she had lost her wallet or the relief check was coming soon or the white people had some money for her. Tomorrow I’d be hiding in the closet because there was only supposed to be two kids in the flat ,and I could hear the rent man shout at my Momma and call her a cheat. And when he finally went away, Momma put the sacks on her shoes and went off to the rich white man’s house to dress the rich white kids so their mother could take them to a special baby doctor.

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

A gentle breeze blew through Jennifer's hair. The golden red sun was setting. She was on the beach, looking up at the fiery (火红的) ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.    

The atmosphere relaxed her. After all she had been through, this was what she needed. "It's getting late," she thought, "I must go home. My parents will be wondering where I am."

She wondered how her parents would react, when she got home after the three days she was missing. She kept on walking, directing herself where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.

It was really getting dark now. The sun had set a few minutes before and it was getting cold too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... It all seemed deserted. She couldn't understand what was going on.    

She entered the house. First, she went into the kitchen where she saw a note written by her father. It said: "Dear Ellen, there is some coffee ready. I went looking." Ellen was her mother but－where was she? On the right side of the hallway was her parents' room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn't slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different－she wasn't in her mother's room and she wasn't wearing the old clothes she ran away in. She was in her cozy bed in her pajamas.     

It felt so good being back home. Suddenly she heard a voice, "Are you feeling better now, dear? You know you got us very, very scared."

Three days later Jennifer came back home      .

A. at sunrise         B. at sunset      C. at night              D. at midday

What does the underlined phrase "This thought" most probably mean?

A. The idea of going back home.           

B. Her anxiety about her parents.     

C. The feeling of being warm in her favorite sweater.     

D. The feeling of getting back home safely.

Her father didn't take care of the garden because      .

A. he was busy looking for her   

B. he had to look after his wife

C. he was not strict with his job        

D. he no longer enjoyed working in the garden

What can we infer from this passage?

A. In fact Jennifer's mother had been sick for days.     

B. As Jennifer walked towards home, she became increasingly scared.     

C. When she found the garden deserted, she realized she was wrong.     

D. Having experienced a lot outside, Jennifer felt home was safest for her.
