I teach geography at UNLV three times per week. Last Monday, at the beginning of class, I cheerfully asked my students how their weekend had been. One young man said that his weekend had not been so good. He had his wisdom teeth removed. The young man then asked me why I always seemed to be so cheerful. “I choose to be cheerful.” I said. Then I told them a story.

In addition to teaching here at UNLV, I also teach out at the community college in Henderson, 17 miles down the freeway from where I live. One day I drove those 17 miles to Henderson. I exited the freeway and turned onto College Drive. I only had to drive another quarter mile down the road to the college. But just then my car died and wouldn’t start again. So I left my car there and marched down the road to the college.

As soon as I got there I called AAA (美国汽车协会)and arranged for a tow truck (拖车) to meet me at my car after class. The secretary in the office asked me what had happened. “This is my lucky day.” I replied, smiling.

“Your car breaks down and today is your lucky day?” She was puzzled. “What do you mean?”

“My car could have broken down anywhere along the freeway but it didn’t.” I replied, “Instead, it broke down in the perfect place: off the freeway, within walking distance from here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class.” The secretary’s eyes opened wide, and then she smiled. I smiled back and headed for class. So ended my story.

I scanned the sixty faces in my class at UNLV. Despite the early hour, no one seemed to be asleep. Somehow, my story had touched them. Or maybe it wasn’t the story at all. In fact, it had all started with a student’s observation that I was cheerful. An Indian wise man once said, “Who you are speaks louder to me than anything you can say.” I suppose it must be so.

1.Why did the author tell his students the story?

A. His story is not convincing

B. He shouldn’t have told the story

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.

1.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

2.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.

3.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.

4.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

A few years ago, my younger brother and I went to Norfolk, Virginian by plane. , before we took off, we heard the pilot’s voice throughout the plane, “sorry for the delay, ladies and gentlemen. We have no on the plane. We have a generator (发电机) on the ground right now, and we are going to the engines with it. Once we get them going, we will 4 in the air and head to Norfolk, and see what happens. ”

See what happens? We are going to get up in the air, and see what happens? At this point, one woman started crying. “Oh, no! We are going to !” There were sighs of desperation and spreading throughout the plane, and we hadn’t even 7 yet. Thirty minutes passed and we were still there. Then the voice of the pilot came over again, “Ladies and gentlemen, I know you are , so are we. We only have one engine going right now, and it is working double time. ”

There was crying we had walked into grave. But, the pilot told us our one engine was working double time, and his was to get up in the air and see what happens! Then we did. We got up in the air and what happened? --- other than thrust (推力) and lift. We arrived in Norfolk and everyone for still being alive.

Although I do sincerely like to have a plan 14 “see what happens”, it really isn’t such a bad life strategy. All too often, I would see people chasing their goals halt (停滞) with inaction just because they don’t have 16 success. Actually, success will never be guaranteed. The thing that you can do is just get up in the air, and see what happens.

If you are planning to learn a new skill, get up in the air, and see what happens! It might not be as as you thought. You might be smarter than you thought. It could be ! So don’t stay there trying nothing just because there is no of guaranteed success.

[1] Are you on Facebook almost every hour of the day? Do you think about being on Facebook even when you are not? If so, you’re suffering from Facebook addiction. Just like any other type of addiction, it can be harmful to a person’s overall life. However, following the few tips can help yourself overcome it.

[2] Admit your addiction to Facebook. Admission is the first step with any addiction. If not, then you can’t be helped. Ask yourself these questions：Are you on Facebook at least every hour? Do you wake up in the middle of the night with the desire to check your Facebook page? Does Facebook interfere with your job performance, family life or daily routine? If you said “yes” to most of these questions, then you could be addicted to Facebook.

[3]List the consequences for using Facebook. Many people don’t realize what negative impact Facebook has on their lives until they make a list. Think about what Facebook addiction is doing to your job, family environment and your overall life and list them all, which helps bring about awareness on what it is really doing to their lives.

[4] ________ . Go under the help section on Facebook and email customer service letting them get your account canceled. For some people this is enough to help them overcome their addiction, but some others may end up turning to some other social networking websites, say, MySpace. In that case, you need to cancel Internet access together.

[5] Seek a professional therapist. Recovering from any addiction can be difficult. Find a therapist specializing in addiction, even better yet someone who is familiar with Facebook addition. The therapist will help you understand where your Facebook addiction stems from and what you can further do to recover from it.
