It was graduation day at the university where I work and a beautiful day quite unlike the first graduation I attended as a young professor．On that cold day years ago, as we watched the students walking into the hall, one of my colleagues turned to me and said, "Graduation will be one of the happiest and one of the saddest time of your life．" At my inquiry, he answered, "Because the students you have gotten to know have to leave．"

As years went by, my previous confusion about my colleague's words no longer existed．When I came across naughty students, I have had to rethink why I chose to be a teacher．It obviously isn't the money．Once a former computer science student of mine called me, asking me if I wanted to have a change．He was working at Nintendo Corporation．His salary was higher than my current one, though I have more education and have worked for over a decade．With my programming skills, he said he could get me hired．I thanked him, but declined his kind offer．

A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework．She thanked me for being her teacher and said the things she had learned in my class—not about math, but about life—would be things she would remember long after the math skills had faded away．As I finished reading, I remembered why I had become a teacher．

Now, on this sunny graduation day, as I again observed the sea of blue hats and gowns, I did so with renewed dedication （奉献） and a deeper sense of satisfaction—I will always be grateful that I am a teacher．

1.Hearing his colleague's description of graduation for the first time, the author __________．

2.The computer science student called up the author because he___________．

3.The underlined part “blue hats and gowns” refers to___________．

4.The author wrote this passage to __________．

Maybe it is true that we do not know what we have got until we lose it, but it is also true that we do not know what we have been missing until it arrives.

It takes an hour to like someone, and a day to love someone, but it takes a lifetime to forget someone. Giving someone all your love is never an assurance that they will love you back. Do not expect love in return; but if it does not, be content it has grown in yours. Do not rely on one’s appearance; it can trick you. Do not rely on wealth; even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright.

There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream; go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do.

The brightest future will always be based on a forgotten past. You cannot go on well in life until you let your past failures and heartaches go off. May you have enough happiness to make you sweet, enough trails to make you strong, enough sorrow to keep you human, enough hope to make you happy. The happiest of people do not necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those appreciate the importance of people who have touched their lives. Always put yourself in others’ shoes. If you feel that it hurts you, it probably hurts the other person, too.

When you were born, you were crying and everyone around you was smiling. Live your life so that when you die, you are the one who is smiling and everyone around you is crying.

NASA’s Mars detector (探测器), Opportunity, succeeded in finding signs that water once existed on the planet. Opportunity landed on Mars in January. Scientists now believe that the planet could once have supported life.

This discovery was chosen by Science, one of the world’s leading magazines, as the most important scientific achievement of 2004 last Friday.

“This little, wheeled, one-armed box went around another planet and has done something no human has ever managed,” according to Science. “It has discovered another place in the universe where life could once have existed.”

“Although we still can’t say that life could have existed in this environment, it is now certain that there was water on Mars,” said Steve Squyres, one of the scientists working on the Mars mission. The evidence comes from pictures and chemical readings taken by Opportunity. It includes marks on rocks like those caused by flowing water on Earth and salty chemicals like those found in dried-out sea-beds. Scientists said the new evidence proved beyond doubt that water has existed on Mars. But it is still unknown whether the water on Mars was like an ocean or just ice.

While Opportunity has not found any signs of life, the presence of water means life is possible. “In everything we know about life on Earth, there is no example without liquid water,” Squyres said. “So water is important for the search for life on Mars.”

Researchers agree that a future mission (任务) should bring back physical samples (样品). But some scientists worry about the risk that this could introduce dangerous foreign creatures to Earth. “The problem here is how to get the samples back,” Squyres replied. “I think it is our responsibility to limit any risk.”

1.________ prove that water existed on Mars.

2.Which of the following is TURE according to the text?

3.How did scientists draw the conclusion that there was water on Mars?

4.It can be inferred that, if the creatures from Mars came to Earth, ________.

You probably have lists of remember and steps to follow in order to have the best pet-friendly trip. There are, however, a few things that are best left at home. Here are a few things to forget when you’re traveling with pets. Forgetting them will make your trip run more smoothly and more effectively.

Time

Traveling with pets will take longer and will have unexpected turns. In reality, forgetting about time means leaving impatience behind. Don’t be in a rush. Your pets will require more extra stops than you will, and they’ll often surprise you with unpredictable delays. Plan on leaving early and arriving later and you’ll be right on time.

Anger

Getting angry at the delay will only make matters worse. Your feelings can add unnecessary stresses to you and your pets’ travel experience. If you feel yourself becoming out of control, stop and take a deep breath. Your pets have little control over their emotions, bowel movements, or motion sickness when traveling. Remember to be kind and understanding at all times, especially when under pressure.

Work Attitude

This may seem like a no-brainer, but when you are traveling, leave your work attitude behind. Traveling is not a task to be accomplished; it can be an enjoyable and memorable experience for both you and your pets as long as you have the right attitude.

Control

Part of the joy of traveling with pets is dealing with the unexpected. You can’t control everything and trying to do so will only end in frustration and anger. Knowing that things will happen beyond your control will bring great relief to you and your pets. Messes happen; accidents happen. Once you accept that, traveling with your pets will be far easier to manage.

Selfishness

Traveling with pets often requires an extreme amount of selflessness. Your pets rely on you to take care of their needs, and sometimes you will need to put their needs before your own. Leave your selfish ambitions behind when traveling with your pets. They need your attention and care more than anything else because of the stresses and strains of traveling.

Traveling with pets can and will be a joy if you remember to leave these five items behind. It can be difficult at times to handle, but the traveling will go well if you can manage to do so.
