A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.
Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.
The largest black holes are called “supermassive”(超大质量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.
When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.The gravity of a black hole may become so strong that light cannot get out when ____________.
| A．the star is going to die |
| B．special tools are used on it |
| C．other stars come close to it |
| D．it is seen from the space telescopes |
According to the passage, which of the following is NOT true?
| A．A black hole can be very tiny but extremely heavy. |
| B．The gravity of a black hole holds all light in its center. |
| C．Scientists observe high-energy light through their own eyes. |
| D．Some small black holes came into being as early as the universe. |
The underlined word “galaxy” in Paragraph 5 means __________.
| A．a black hole | B．the Milky Way |
| C．a series of stars | D．a planet near the earth |
What does the last sentence in Paragraph 5 suggest?
| A．Neither the sun nor the earth is as heavy as a black hole. |
| B．There is a supermassive black hole at the center of the Milky Way. |
| C．The supermassive black hole had existed before the Milky Way was formed. |
| D．There is a reason why the large black holes are called “supermassive”. |
The last two paragraph mainly focus on the question of _________.
| A．what a black hole is |
| B．how black holes form |
| C．how big black holes are |
| D．how scientists know about black holes |
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 (鞋套) over their shoes because it was so wet and cold. I wonder how they managed 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 hot-water pipes were frozen and the wind came in through the holes in the wall. She’d have to deal with the mice: leave some food out for them so they 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 finished 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 (房租) 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 make up some other excuses. Tomorrow I’d be hiding in the closet (橱柜) because there should be only 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.

It is possible to do many simple tricks with numbers. Here is one trick. It has seven steps.
First, write down your house number. For example, if your address is 73 Lemon Street, you would write down 73.
Next, double it. In other words, multiply(乘) it by two. Then, add five to this doubled number. For example, if your address was 73 and you doubled it, you would get 146. Then, if you added five, you’d get 151.
So, to repeat the first three steps, write down your house number, double it, and add five.
Fourth, multiply this number by 50. In our example here, if you multiply 151 by 50, you’ll get 7550.
The fifth step is to add your age to this total. For example, if you’re 26 years old, you should add 26 to this total. In our example here, the result would be 7550 plus 26, you’ll get 7576.
Sixth, you have to add the number of days in a year, which is 365. In our example here, 365 added to 7576 is 7941.
The seventh and final step is this: subtract(减) 615 from the number that you have. In our example, 7941 minus 615 is 7326.
The result here, 7-3-2-6, is the trick. The first part of the number is the address and the last part of the number is the age of the person. That is, 73 is the address that we started with, and 26 is the age that we used.
If you follow these seven steps with any address and the age of any person. You will get the same result.
73 According to the trick, what number can you get if you are 16 years old and your house number is 85？
A. 1685 B. 8516 C. 8165 D. 1658
74. How can your age number appear at the last part of the result?
A. It’s really a trick.
B. By
taking all the steps except Step1 and Step 2.
C. By taking Step 6 and Step 7.
D. By taking all the steps.
75. What’s the secret of the trick?
A. It’s impossible to know.
B. By taking Step 2 and Step 4, we get the formula(公式)：your address number ×2×50.
C. By taking all the steps except 1 and 2, we get the formula: 5×5
0+your age number+365－615="your" age number.
D. Both B and C.

Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.
No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.
There's more good news for people, if they have friends. These people live longer than those people if those don't have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that 
someone cares, if someone cares about you, you take better care of yourself.
