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. |
Which can be inferred from the passage?
| A．Every galaxy must have a black hole. |
| B．A galaxy is the center of the universe. |
| C．A galaxy consists of a large group of stars and planets. |
| D．Earth’s galaxy is called the Milky Way. |
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 only one 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”.
65. 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

During my free time one day, I wandered down a lonely path into the woods and sat against a tree. Then I saw one of the camp counselors approaching me. "Oh great," I thought, since counselors were always trying to cheer you up or make you laugh.
"Hey," he said, "mind if I have a seat?" I shrugged(耸肩). I wasn't going to encourage him, but I couldn't exactly stop him, either. He sat down alongside me and extended a hand. "I'm Gary," he said, "and you're Erica, right?" I nodded. "You don't exactly look like you're having a good time," he began.
I crossed my arms and gritted my teeth. "Look," I said, "I didn't want to come to camp, I don't like it, I'm not having fun, and it basically stinks." I glared at Gary.
"So there's nothing here at all for you, huh?" he asked.
"Nothing," I answered.
"Let me show you something," said Gary. He got up, and I followed him along the path until I heard a sound like a roaring freight train.
"What's that?" I asked.
"Wait and see," he replied, with a small smile.
When we rounded the corner, I couldn't believe what I saw. There was the biggest waterfall I could ever imagine, right in front of me. "Cool!" I said, and I could feel my eyes getting bigger and a smile tugging at my mouth.
"Still think there's nothing here for you?" asked Gary. "Because there's a whole lot more of this kind of 'nothing' around here."
I had to admit, the waterfall was impressive.
"Look," said Gary, "camp is what you make it. You can be sullen(阴郁的) and closed-minded and have a rotten four weeks, or you can take a look around you and see some of the incredible sights and appreciate the opportunity. It would be useless for me to try to make you have fun. You can only do that for yourself. But if you loosen up a little, you might actually have a good time." With that, he turned and walked away, leaving me on the path.
That night, by the campfire, I found myself singing along with everyone else. By the time the four weeks were up, I didn't want to leave. I'd seen some amazing things and made some great friends.
Beauty is where you find it. Life is what you make it. I think it's going to be a good year this year. I mean, I'm going to work to make it one. Maybe if I'm lucky, I'll get to go back to camp next year!When Gary walked to Erica, you could predict that ________ .

Mother stayed at home cooking and cleaning while Father left for work. Two or more children took the bus to school. In the evening, all the family members got together at home again. This is what a traditional family was like twenty years ago. But now great changes have happened in British families.
As many as 2 out of 3 marriages now end in divorce(离婚), and many children have to live with one parent and only see the other at weekends or during holidays.
There has been a great increase in the number of working women with children. Many women have to work to support themselves and their children. Even in the family where there is no divorce, both parents have to work in order to survive.
Also women are no longer happy to stay at home taking care of children. Many of them have jobs and some of them can even make more money than men, the traditional breadwinners.
What’s more, the increasing number of single-parent families have caused an increase in the crime rate (犯罪率) among children in a way. It is thought that if a child doesn’t have a father, he or she will be harmed.
However the changes may be good for some people. For women it’s now much easier to have well-paid jobs. Although it is difficult to be a working mother, it is no longer seen as a bad thing for children.

You wake up in the morning，the day is beautiful and the plans for the day are what you have been looking forward to for a long time．Then the telephone rings，you say hello, and the drama starts．The person on the other end has a depressing(令人沮丧的) tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to．You are still in a wonderful mood? Impossible!
Communicating with negative people can wash out your happiness．It may not change what you think，but communicating long enough with them will make you feel depressed for a moment or a long time．
Life brings ups and downs，but some people are stuck in the wrong idea that life has no happiness to offer．They only feel glad when they make others feel bad．No wonder they can hardly win others’ pity or respect．
When you communicate with positive people，your spirit stays happy and therefore more positive things are attracted．When the dagger(匕首)of a negative person is put in you．you feel the heavy feeling that all in all，brings you down．
Sometimes we have no choice but to communicate with negative people．This could be a co-worker，or relative．In this case，say what needs to be said as little as possible． Sometimes it feels good to let out your anger back to a negative person，but all this does is to lower you to that same negative level and they won’t feel ashamed of themselves about that．
Negativity often affects happiness without even being realized．The negative words of another at the start of the day can cling to(附着)you throughout the rest of your day，which makes you feel bad and steals your happiness．Life is too short to feel negative．Stay positive and avoid negativity as much as possible．The purpose of the first paragraph is to __________ ．
