题目列表(包括答案和解析)

  The television camera is rather like the human eye.Both the eye and the camera have a lens(镜头),and both produce a picture on a screen.In each case the picture is made up of millions of spots of light.

  Let us see how the eye works.When we look at an object a person, a house, or whatever it may be we do not see all the details of the object in one piece.We imagine what we do, but this is not the case.In fact, the eye builds up the picture for us in our brain, which controls our sight, in millions of separate parts, and, although we do not realize it, all these details are seen separately.

  This is what happens when we look at something.Beams of light of different degrees of intensity(强度), reflected from all parts of the object, strike the lens of the eye.The lens then gathers together the spots of light from these beams and focuses them on to a light sensitive plate the retina(视网膜)at the back of the eyeball.In this way an image of the object is produced on the retina in the form of a pattern of lights.

  The retina contains millions of minute light sensitive elements, each of which is separately connected to the brain by a tiny fibre in the optic(视力的)nerve.These nerve fibres, working independently, pick out minute details from the image on the retina and turn the small spots of light into nerve impulses(冲击)of different strengths.They then transmit these impulses to the brain.They do this all at the same time.

  All the details of the image are fed to the brain, and, as we have taught our brain to add them together correctly, we see a clear picture of the object as a whole.

  Television, which means vision at a distance, operates on a similar principle.A television picture is built up in thousands of separate parts.

  Beams of light reflected from the subject being televised strike the lens of the television camera, which corresponds to(相当于)the lens of the eye.The camera lens gathers together the spot of light from these beams and focuses an image of the subject on to a plate, the surface of which is coated with millions of photo electric elements sensitive to light.

  Adults(成年人)usually do not remember most of the things that are taught by their teachers at school.But this story is one such lesson that I will never forget.Every time I drift off course, I think of this story.

  It was a normal Monday morning, and my teacher was teaching us on important things in life and about devoting ourselves to what is important to us.This is how the story went:

  An old man lived in a certain part of London, and he would wake up every morning and go to the subway.He would get onto the train right to Central London, and then sit at the street corner and beg(乞讨).He would do this every single day of his life.He sat at the same street corner and begged for almost 20 years.

  His house was dirty, and a stench(恶臭)came out of the house and it smelled terrible.The neighbors could not stand the smell any more, so they called for the police officers to clear the place.The officers knocked down the door and cleaned the house.There were small bags of money all over the house that he had collected over the years.

  The police counted the money, and they soon realized that the old man was a millionaire(百万富翁).They waited outside his house expecting to share the good news with him.When the old man arrived home that evening, one of the officers told him that there was no need for him to beg any more as he was a rich man now, a millionaire.

  But the old man said nothing at all; he went into his house and locked the door.The next morning he woke up as usual, went to the subway, sat at the street corner and continued to beg.

  Clearly, this old man had no great plans, dreams or anything significant(有意义的)for his life.We learn nothing from this story other than(除了)staying focused on(专心于)the things we enjoy doing.
