    Have you found this? Sometimes, on grey, rainy days, your mood level is lower than on bright, sunny days. Is this a coincidence（巧合）, or is there some science behind this? Would you like to know more about how the weather can affect how you feel?

    According to a recent study, there is a connection between weather and moods. Going to a warm place in the middle of winter can make our moods better. Pleasant weather has been proved to improve moods and memory. However, extremely hot weather can actually make us feel more tired and bored, spoiling our moods.

In the study, people who spent time outdoors in warm weather were happier than those who spent all day inside.

    The best temperature for humans is about 22.2℃. That explains why people in southern California are happy all the time. To improve his or her moods, a person must spend at least 30 minutes outside in warm, sunny weather. Spending time indoors when the weather outside is so nice tends to lower moods.

    Maybe just the activities connected with being outside affect our moods. Warm weather is connected with the beach, fun outdoor sports and so on. It brings back childhood memories of playing outside all day. Who doesn't love that?

    Of course, we can wake up every day and decide how we will feel that day. If it's rainy, that won't necessarily make us unhappy. We'll just have to bring our umbrellas out and cheer up those who are feeling sad!

    After （listen） to her, the older woman felt her pain and knew that she could never help her get out of it, she could teach. She said, "Tonight, take your best feather pillows（枕头） and put every feather on the doorstep of each house in the town before the sun （rise）."

    The young woman hurried home （get） the pillows which were very dear to her. All night long, she went from doorstep door step, putting down the feathers carefully. Finally, just as the sun rose, she finished the work and returned to the older woman.

    "Now, "said the wiser woman, "go back and collect all the feathers. Then everything will be as it was before. "The young woman was （surprise）. "You know that's impossible! The wind blew away each feather as fast as I placed them on doorsteps!"

    "That's true," said the older woman. "Never forget each of your （word） is like a feather in the wind. Once spoken, nobody can ever help you return to your mouth."
