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”. |
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 |
With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dump, makes me feel good and warms my heart.
How would you feel if you could not joke around with your wife, husband, child, co-worker, neighbor, close friends, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy(礼貌)to speak to others that are around you.
I know of a few people that don’t have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?
Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to ignore the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together. According to the author, humor is useful in the aspect that _________.
| A．it makes people more confident |
| B．it can pick up people’s spirits |
| C．it can help get rid of the cruelty in the world |
| D．it can help people get on well with others |
From the second paragraph, we can know that __________.
| A．the writer is funny and polite |
| B．family members should play tricks on each other |
| C．the writer’s grandma is humorous |
| D．we should relieve stress in any situation |
The phrase “busting a gut" in the third paragraph can be replaced by _______.
| A．explaining carefully |
| B．speaking loud |
| C．keeping silent |
| D．laughing hard |
In writing the passage, the author mainly intends to _______.

Countless people long to make a difference this holiday season, yet they don’t realize that opportunities to make a difference are everywhere .Here are some ideas to get you started.
Organize a blank drive
It is cold outside, but imagine how thousands of homeless people may feel without a home of their own, or even a blanket to keep them from the cold. Organize a blank drive for your local homeless, and ask around for donations!
Practice random acts of kindness
I’ll never forget the time when I went to pay for my Dr. Pepper, but the sever resisted, saying my bill was paid by an anonymous(匿名的) guest. It’s this random act of kindness that restores my faith in humanity. Bless someone by paying for their drink at Starbucks, or praising them! If you live somewhere where it snows, shovel your neighbour’s snow out of their driveway for them! Whether it is as simple as praise or as complex as paying the bill, you’ll never know how far your impact will reach.
Say thank you
Just a simple thank-you can make somebody’s day, especially if they feel like their work is never noticed. Cultivate（培养） a smile on their face by being sincere and grateful for all that they do.
Use your talents to help the community
The best way to show your appreciation for people is by using the talents and skills you have to bless others. For me, I love to coordinate（协调） events and write , and so my way of reaching out to the community is through writing articles and creating awareness about problems we face today. If you can bake, make some delicious cookies for people to enjoy! If you can knit, put your talents to use by making clothes for children in foster care. Any talent can be used to help the community in meaningful ways.

A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.
The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003.
Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.
The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.
“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,” wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg.
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.
“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施),” the authors wrote.
Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability.
The authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health outcomes.
However, the researchers said a pattern was clear. “We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic,” the authors concluded.According to the study, who made the most accurate prediction of their future life satisfaction?
| A．Optimistic adults. |
| B．Adults of lower income. |
| C．Adults in poor health. |
| D．Middle-aged adults |
Pessimism may be positive in some way because it causes people ______.
| A．to fully enjoy their present life |
| B．to take measures against potential risks |
| C．to estimate their contribution accurately |
| D．to value health more highly than wealth |
How do people of higher income see their future?
| A．They will suffer mental illness |
| B．They will become pessimistic. |
| C．They will earn less money.. |
| D．They will have less time to enjoy life. |
What is the clear conclusion of the study?
| A．Pessimism guarantees chances of survival. |
| B．Good financial condition leads to good health. |
| C．Expectations of future life satisfaction decline with age. |
| D．Medical treatment determines health outcomes. |
The technology is great. Without it we wouldn’t have been able to put a man on the moon, explore the ocean’s depths or eat microwave sausages. Computers have revolutionized our lives and they have the power to educate and pass on knowledge. But sometimes this power can create more problems than it solves.
Every doctor has had to try their best to calm down patients who’ve come into their surgery waving an Internet print-out, convinced that they have some rare incurable disease, say, throat cancer. The truth is usually far more ordinary, though: they don’t have throat cancer, and it’s just that their throats are swollen. Being a graduate of the Internet “school” of medicine does not guarantee accurate self-health-checks.
One day Mrs. Almond came to my hospital after feeling faint at work. While I took her blood sample and tried to find out what was wrong, she said calmly, “I know what’s wrong; I’ve got throat cancer. I know there’s nothing you doctors can do about it and I’ve just got to wait until the day comes.”
As a matter of routine I ordered a chest X-ray. I looked at it and the blood results an hour later. Something wasn’t right. “Did your local doctor do an X-ray?” I asked. “Oh, I haven’t been to the doctor for years,” she replied. “I read about it on a website and the symptoms fitted, so I knew that’s what I had.”
However, some of her symptoms, like the severe cough and weight loss, didn’t fit with it—but she’d just ignored this.
I looked at the X-ray again, and more tests confirmed it wasn’t the cancer but tuberculosis (肺结核)—something that most certainly did need treating, and could be deadly. She was lucky we caught it when we did.
Mrs. Almond went pale when I explained she would have to be on treatment for the next six months to ensure that she was fully recovered. It was certainly a lesson for her. “I’m so embarrassed,” she said, shaking her head, as I explained that all the people she had come into close contact with would have to be found out and tested. She listed up to about 20, and then I went to my office to type up my notes. Unexpectedly, the computer was not working, so I had to wait until someone from the IT department came to fix it. Typical. Maybe I should have a microwave sausage while I waited?Mrs. Almond talked about her illness calmly because ______.
| A．she had purchased medicine online |
| B．she thought she knew it well |
| C．she graduated from a medical school |
| D．she had been treated by local doctors |
It was lucky for Mrs. Almond ______.
| A．to have contacted many friends |
| B．to have recovered in a short time |
| C．to have her disease identified in time |
| D．to have her assumption confirmed |
Mrs. Almond said “I’m so embarrassed” (Para. 7) because ______.
| A．she had caused unnecessary trouble |
| B．she had to refuse the doctor’s advice |
| C．she had distrusted her close friends |
| D．she had to tell the truth to the doctor |
By mentioning the breakdown of the computer, the author probably wants to prove _____.
| A．it’s a must to take a break at work |
| B．it’s unwise to simply rely on technology |
| C．it’s vital to believe in IT professionals |
| D．it’s a danger to work long hours on computers |
