No one can change the weather. But if we read the signs around us correctly, we can tell how the     19     will be. This way of telling what the weather will be like     20     the following day or two is called weather forecasting. For many centuries and in all countries, people have     21     the weather and tried to make weather forecasting. Rings around the sun are a     22     of coming rain. Many people feel in     23     bones the coming of wet weather—they feel joints (关节) pain. Some birds fly     24     if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because the insects (昆虫) which they are hunting fly low.

    25     you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle (闪烁) clearly at     26    , then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset (日落) is mostly red in colour, then the following day will be     27    . If a rainbow appears in the morning,     28     weather will probably come. You should take an umbrella with you when you go out. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.
