　　 28.[A]Weather forecast is getting more accurate today.

　　 [B]People can predict the weather by their senses.

　　 [C]Who are the real experts in weather forecast.

　　 [D]Weather changes affect people's life remarkably.

　　 原文:To find out what the weather is going to be,most people go straight to the radio,television,or newspaper,to get an expert weather forecast.But if you know what to look for,you can use your own senses to make weather predictions.【第28题答案位置】There're many signs that can help you.For example,in fair weather,the air pressure is generally high;the air is still,and often full of dust.And faraway objects may look vague.But when the storm is blowing,the pressure drops,and you are often able to see things more clearly.Sailors took note of this long ago,and came up with the saying,“The farther the sight,the nearer the rain.”Your sense of smell can also help you detect weather changes.Just before it rains,odors become stronger.This is because odors are repressed in a fair high pressure center.When a bad weather moves in,air pressure lessens,and odors are released.You can also hear an approaching storm.Sounds bounce off heavy storm clouds and return to earth with increased force.An old saying describes to this way,“Sound traveling far and wide,a stormy day will be tied.”And don't laugh at your grandmother if she says she can feel a storm coming.It is commonly known that many people feel pains in their bones or joints while the humidity rises,the pressure drops,and bad weather is on the way.
