Title:
Is X-Ray Examination Necessary’
Issue
Students, can you show me your hands? Right! And can you show, me your head? Excellent! But... Can you show me your stomach’ Hm Can you show me your lungs’ No ‘Why’ Yeah, you’re right Because they are inside our body. So what do you think, how can we see the internal parts of our body? Yes. We use X-Ray So, what is X-Ray’ Does anybody know’ No …Well, X-Ray is a spectrum of light It is radiated to our body It is used for detecting our internal body organs .Do I make myself clear? Well, Let me continue, where can you find X-Ray’ Yes, that’s right It is in a hospital And do you know who invented X-Ray’ Does any­ body knows’……Oh come on Nobody remembers the name~ Well, X-Ray was invented by a German scientist, William Conrad Rontgen. Where was I? Oh, O.K. Hm... When do people use X-ray? Correct. When they need X-Ray to check. Yes, cancer, . . .kidney trouble, .. .heart trouble, . . .tumor, etc.
Students do you know many opinions argue about the use of X-Ray in hospital and others agree about the use of X-Ray?

Argument “for” point Elaboration
Well, some people agree that X-Ray examination is beneficial.
They say that doctors should use X-Ray in examining a severe illness. If doctors don’t use the X-Ray, they will miss some important information which is very useful in making a diagnose on the patient’s disease. And this will sometimes cause the doctor inaccurate in prescribing the medicine to cure the illness.

Argument “against” point Elaboration
Not all patients agree with the use of X-Ray exami­nation, however.
Do you know why? Guess what?
They think that using X-Ray examination will cost them a lot of money. I’m not surprised. Another rea­son is the radiation of X-Ray has some risks to the body tissues.
Conclusion
Well, as a result of this controversy, many people are planning a traditional health cure to avoid, the high cost of hospital care. While hospitals insist on having X-Ray examinations on patients to get an accurate diagnose although the cost is very high.

The Controversy of Harnessing Solar Energy

We often hear about solar car, solar heating or solar batteries. But will solar energy ever be a major source of energy for industrial societies? The solar energy is cheaper than any other fossil fuel because we can
Unfortunately, we can’t yet power our homes entirely on sunlight. Solar energy can only be exploited in bright light. Its greatest poten­tial, therefore is in hot countries that have clear skies for most of the year. While most houses are not always in the sunniest part of the world. In addition, to harness the solar power, solar cells are needed to convert the sunlight directly into electricity. Solar cells are very cheap to run, but relatively expensive to buy and many people can’t afford it.
In sunny desert areas, 50% of the sun’s radiation that reaches the ground could be used to produce electricity for businesses and indus­try to provide heat, light and hot water for homes. Experimental solar ponds can produce hot water to drive generators.
Needless to say that solar energy is a useful and non-polluted source of energy. Nevertheless, solar cells, the main important device to harness the sun’s energy is still very expensive.
