Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, farm tractors(拖拉机), rock music is also noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant(不断的) loud noise can cause a loss of hearing.
Scientists use a unit of measure called decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level(层次) causes the great hearing loss.

I do not need a calendar to tell me when it is winter. All I need is my nose. When I wake up in the morning and smell the tasty treats my mom is cooking downstairs, I know winter has arrived.
The first one is the smell of chocolate. During the holiday season (from Thanksgiving to New Year’s Day) my mother makes her special hot chocolate. She always adds a peppermint candy cane (薄荷味拐棍糖) to the drink and tops it with cream.
The hot chocolate gets me out of bed, but it is my mother’s chocolate fudge (软糕) that makes me run downstairs. It is a thick chunk (块) of chocolate that tastes like heaven. My mother adds nuts. That gives it more texture (质感).
But my mother isn’t done yet. She also makes a treat she calls “window panes (窗玻璃)”. She takes a few different colored marshmallows (棉花糖) and melts them together with chocolate. The final product looks like a colorful church window, so we call it “window panes”.
These tasty holiday treats are usually eaten after a meal as a dessert. But don’t tell Santa Claus because I secretly eat them all day long.
【小题1】What wakes “me” up in the morning?
