　　In the near future some parts of the world may soon have a new kind of television. It is called high definition television or H-D-T-V. The main difference between H-D-T-V and normal television is the picture. It is more clear and detailed (明细). This is because H-D-T-V has many more points and lines that make a television image (图像). Every colour television picture contains thousands of red, green and blue points, They all come together as an image in the eye of the person

watching. The points are organized in lines that go across the television screen. There are more than 500 lines in a normal television. H-D-T-V has two times as many. To get this clear picture, you must have a big screen. Experts say people using a small screen will see little difference.

　　H-D-T-V also has clear sound. It is like the sound on a compact disc player (激光电唱机), or CD. All these improvements make H-D-T-V very costly. One kind in Japan now sells for more than 20 000 dollars. In the future, the cost is expected to be about 2 000 dollars. A major problem with H-D-T-V is its broadcast signal. The signal is bigger than for normal, because it carries more electronic in formation.

As a substitute teacher, my daily routine involves driving to a new school almost every day so I’m usually unable to anticipate the day’s events, good or bad!
On one particular day, I was teaching in a very difficult classroom. I was managing behavior all morning and by lunch time, I knew I needed coffee to even consider surviving the afternoon. So on my lunch break, I drove to a nearby plaza（购物中心）to get a cup of coffee. Upon returning to the car I realized I had locked my keys and my phone inside! I had about 15 minutes to get back to the school which was a good 4 or 5-minute drive away. I contemplated  (思考）sprinting（冲刺）back, but it being winter, I thought a nasty fall on ice would only make the situation much worse.
So I ran into a McDonald’s which was in the same plaza and asked the man at the counter who happened to be the manager to please call me a cab. I briefly explained my situation to him, and I could tell by the look in his eyes, that he empathized. He hurried to the back to use the phone while I paced in the restaurant. I had less than 10 minutes to get back to my school at this point.
The manager returned only to tell me that the cab company had put him on hold and then the line got disconnected, and that he was now on hold again, but had not yet been able to request the cab yet. My expression, I assume, began to resemble some combination of hopelessness and fear.
Without a thought, he grabbed his coat and offered to drive me to the school. Without hesitation, I followed him into his car and made it back into my classroom with 2 minutes to spare before the bell!
Upon arriving at the school, I thanked this man endlessly. His calm demeanor（举止）and kind nature made me think he was probably a wonderful manager to work for, and also a wonderful human being to have on this earth. This experience makes me realize that out of every seemingly hopeless situation, there is the opportunity for acts of kindness to transpire（发生）, which can have an unimaginable impact on those who receive them.
