Sometimes giving someone a helping hand is just simple.But sometimes it works like a 36 that opens a door to a whole new world of understanding.

Living in a small all-white  37  in the Midwest, my family and I were 38  that we were safe from the race riots (暴乱) in some larger cities.That  39  when I began working at a bank in a larger city nearby.My family  40  gave me advice on whom to avoid, what situation to stay away, and how to  41  myself.

On a snowy  42  after work, I guided my second-hand car out onto the street and knew  43 I didn't have to stop, it would keep running.The battery needed replacing.

However, as I expected the car choked and died at a red light.Fortunately, to my  44 ,I saw a pair of headlights coming up.But  45  three young black men jumped out of the car, I could hardly  46 - fear filled me.

The driver came to my windows and asked if I needed help.I  47 for a moment and then nodded.The fellows crowded around at once and  43__ working.As one of them connected the two engines by cables, my nerve (神经) jumped with so much electricity I think I could have charged the 49 and brought it back to life.But thankfully they 50 completed the project.

I pulled out a few  51 from the purse, "It's all I have but it's yours, I appreciate the help.Thank you."

The driver must have seen the 52  still in my eyes because he smiled, seeming to be 53 by my panic, and then waved his hand, "You  54  it.Just glad to help."

This experience taught me that I should never simply  55 anyone according to their skin color or race or wealth.

  Your body is made up of little cells(细胞).Each one of these is alive. The big difference between your body and a man-made machine is that every part of your body is alive. Each cell has a job to do and needs energy to do it. If you count correctly, you will find the total is around 60,000,000 cells.

  Nerve(神经)cells have long thread like shapes. Bone cells may have branching parts to link with other cells, while red blood cells are round and almost flat.

  The cells are alive, but they do not live nearly as long as you do. Each cell lives for a while--from a few weeks to a year or more--and then it dies and a new cell is made to do the same. Only one kind of cell is not made after birth, the brain cells. So a new born baby is the brainiest person in the world, he has a full set of brain cells in thinking.

  All our lives, we are storing more and more information in the brain. The fastest rate is at the time when we are young.

(1) Which one of the following is right?

[  ]

A.Everything in the world is made up of little cells.

B.Nothing has cells but people.

C.The man-made machine's cells are dead.

D.Your legs are made up of little ceils.

(2) The amount of cells in a human body is ______.

[  ]

A.about sixty billion

B.about sixty million

C.less than sixty million

D.more than sixty billion

(3) The shapes of cells in the human body are ______.

[  ]

A.about the same

B.almost round or flat

C.changed at any time

D.quite different

(4) _______ after birth.

[  ]

A.Each kind of cell can be made

B.Not all cells can be made

C.The brain cells are changeless

D.The new cells are made unlimitedly

  I was on a train the other day, in an empty compartment (n.火车中的小房间), and I wanted to read the last part of a detective story. Then the door opened and a mother with two small children asked me,“May we sit here, Madam?”At first I wanted to say,“well, actually, I'm reading an exciting book and I'd like to finish it. Could you find another compartment?”

  But of course I said,“Yes, certainly,”I still had not finished that book. Unfortunately, I found it very difficult to say“No” to those magic words“May I...”or“would you mind if I...”

  Of course people usually ask permission to do quite harmless things, like using the telephone, turning the light on, opening the window and things like that. But then there are some funny requests. Some people even ask if they may wash their hands or take their coats off. On the other hand, very few smokers will bother to ask permission to smoke!

  But what about those difficult requests like,“Do you mind if I come round for a cup of coffee?”, or“Is it all right if I bring the children to the party? They're very good really.”The trouble is, I just don't have the nerve (n.神经) to refuse Well, do you?

(1)The writer describes those requests as“magic words”because they ________.

[  ]

A.are amusing

B.are harmless

C.always work

D.are easily understood

(2)The writer let the mother and her children share the compartment with her out of ________.

[  ]

A.politeness

B.curiosity

C.business

D.sympathy

(3)According to the writer, asking permission to smoke is ________.

[  ]

A.a foolish request

B.a difficult request

C.an unnecessary request

D.none of the above

(4)Difficult requests are those which ________.

[  ]

A.are never premitted

B.are never refused

C.make other people uneasy

D.make other people unfortunate

(5)Which of the following may express the main idea of the passage? ________

[  ]

A.I'm a polite person.

B.Requests of different kinds.

C.How to make a request.

D.How to answer a request.

  What are you doing right now?Yes, you are reading this page.That also means you’re moving your eyes.You’re thinking.You’re breathing.You’re listening.Possibly you’re shifting(变换)positions.You’re also feeling things-this book, your chair, emotions.What lets you do all these things at the same time?Your brain.

  Your brain is the control center of your body and mind.Without your brain you can’t do anything.Your brain has more than 100 billion nerve(神经)cells.Each nerve cell makes from 1,000 to 10,000 connections with other nerve cells.The nerve cells send impulses back and forth in your brain and to and from every part of your body.After you reach the age of 20, though, your brain cells start to die.This is common.However, if you suffer an illness, or injury, even more nerve cells die in your brain.When a nerve cell dies, the thousands of connections it made with other nerve cells are lost.

  Until recently, scientists believed that the brain did not replace its dead cells.New studies, however, prove not.Scientists have found new nerve cells in a part of the brain called the hippocampus(海马区).The hippocampus helps the brain form memories from new experiences.

  The discovery of these new nerve cells is not a cure for anything yet.It gives hope, however, of a cure for brain damage from such things as epilepsy(癫痫病), Lou Gehrig’s disease, car accidents, and strokes.Someday scientists might be able to use the new cells to replace damaged brain cells.Such a cure, however, may take about ten years to develop.So at the same time, use your head-protect it!

(1)

Nerve cells in the brain ________.

[  ]

A.

send massages to every part of the body

B.

make connections only to other cells in the brain

C.

can cure Lou Gehrig’s disease

D.

are a person’s memory

(2)

[  ]

A.

should use their head by carefully thinking through situations

B.

should be careful not to injure their brains

C.

have a skull(头盖骨)that provides all the protection needed by the brain

D.

would see a quick cure for brain disease

(3)

The author explains what the hippocampus is by ________.

[  ]

A.

telling its history

B.

comparing it to other parts of the brain

C.

telling how it got its name

D.

explaining what it does

(4)

Nerve impulses are ________.

[  ]

A.

cures

B.

disorders

C.

memories
