In the kitchen of my mother’s houses there has always been a wooden stand (木架) with a small notepad (记事本)and a hole for a pencil.

I’m looking for paper on which to note down the name of a book I am recommending to my mother. Over forty years since my earliest memories of the kitchen pad and pencil, five houses

later, the current paper and pencil look the same as they always did. Surely it can’t be the same pencil?The pad is more modern, but the wooden stand is definitely the original one.

“I’m just amazed you still have the same stand for holding the pad and pencil after all these years.”I say to her, walking back into the living-room with a sheet of paper and the pencil. “You still use a pencil. Can’t you afford a pen?”

My mother replies a little sharply. “It works perfectly well. I’ve always kept the stand in the kitchen. I never knew when I might want to note down an idea, and I was always in the kitchen in those days.”

Immediately I can picture her, hair wild, blue housecoat covered in flour, a wooden spoon in one hand, the pencil in the other, her mouth moving silently. My mother smiles and says, “One day I was cooking and watching baby Pauline, and I had a brilliant thought, but the stand was empty. One of the children must have taken the paper. So I just picked up the breadboard and wrote it all down on the back. It turned out to be a real breakthrough for solving the mathematical problem I was working on.”

This story—which happened before I was born—reminds me how extraordinary my mother was, and is, as a gifted mathematician. I feel embarrassed that I complain about not having enough child-free time to work. Later, when my mother is in the bathroom, I go into her kitchen and turn over the breadboards. Sure enough, on the back of the smallest one, are some penciled marks I recognize as mathematics. Those symbols have travelled unaffected through fifty years, rooted in the soil of a cheap wooden breadboard, invisible (看不到的) exhibits at every meal.

46.Why has the author’s mother always kept the notepad and pencil in the kitchen?

A.To leave messages.

B.To list her everyday tasks.

C.To note down maths problems.

D.To write down a flash of inspiration.

47.What is the author’s original opinion about the wooden stand?

D.It should be passed on to the next generation.

48.The author feels embarrassed for .

A.blaming her mother wrongly

B.giving her mother a lot of trouble

C.not making good use of time as her mother did

D.not making any breakthrough in her field

D.careless about her appearance

D

To err is huaman. To blame the other guy is even more human.

Common sense is not all that common.

Why tell the truth when you can come up with a good excuse?

These three popular misquotes(戏谑的引语)are meant to be jokes, and yet they tell us a lot about human nature. To err, or to make mistakes, is indeed a part of being human, but it seems that most people don’t want to accept the responsibility for having made a mistake. They naturally look for someone else who could be responsible for the problem. Perhaps it is the natural thing to do. The original quote about human nature went like this:“To err is human, to forgive, divine(神圣的).”This saying mirrors an ideal: people should be forgiving of others’ mistakes. Instead, we tend to do the opposite-find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a mark of great maturity.

Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company,“the right hand does not know what the left hand is doing.”

And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of common problems with making excuses is that people, especially young people, get the idea that it’s okay not to be totally honest all the time. There is a corollary(直接推论)to that: if a good excuse is“good”even if it isn’t honest, then where is the place of the truth? 51.According to the passage, which of the following seems the most human?

A.To search for truth.

B.To achieve one’s ideal

C.To make fun of others’ mistakes.

D.To criticize others for one’s own error.

52.According to the author, what is a sign of a man’s maturity?

A.Doing things his own way.

B.Bearing responsibility for his mistakes.

C.Making as few mistakes as possible.

D.Thinking seriously about his wrongdoings.

53.Which of the following is NOT based on common sense?

A.A man tries to take charge of everything in a large company.

B.A student goes out with an umbrella in stormy weather.

C.A company’s next move follows good plan.

D.A lawyer acts on fine judgments.

54.What is the author’s opinion about a good excuse?

A.Making a good excuse is sometimes a better policy.

B.Inventing a good excuse needs creative ideas.

C.A good excuse is as rewarding as honesty.

D.Bitter truth is better than a good excuse.

55.What would be the best title for this passage?

A.A Mirror of Human Nature

B.To Blame of to Forgive

C.A Mark of Maturity

D.Truth of Excuse
