Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in a million.
People have made a census (普查) to colors of mor e than four thousand kinds of flowers and discovered that only eight of them are black.
As we know, sunlight is formed by seven different colored lights.The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals, are easy to be harmed by light temperature.
Black flowers can take in all the light waves which cause the flowers to dry up in the high temperature. So black flowers can rarely survive sunlight. But red flowers, yellow flowers and orange flowers can protect themselves from sunlight by reflecting the red light, yellow light and orange light, each of which has a large quantity of heat.

I had this exchange with my 6-year-old last week.
Him: Mom, we have to start buying Danimals.
Me: Why?
Him: So, I can bring it to |school for lunch.It's yogurt .
Me: Why do you want it so badly?
Him: Because Danimals i|s giving away five fantastic Caribbean vacations.
I had to explain that there was little chance that he would win a vacation.It's a strategy used to encourage kids to beg for artificially-colored (人工着色的) yogurt that costs a lot.
Marketing follows my kids —and yours—wherever they go .It comes via TV commercials. Store displays and websites are also constantly selling at our kids .But the most powerful means in kids" lives is the presence of licensed characters on every product imaginable.
Children can begin their day in character clothing.There's even character -themed wall paint available.A breakfast in a character bowl can be followed by a character toothbrush and character toothpaste(牙膏), character soap and shampoo, and a character wash cloth and towel .Then, they can put on character clothing and character shoes.Check that, character clock on the wall: Is it time for characier-shaped fruit snacks yet?
Surround kids with enough of the characters and they'll come to believe they need them.Most of us, of course, don't buy all those items.But say no to four products out of five and your home can still get filled with these tiny items encouraging brand loyalty (品牌忠诚)
At this time of year, parents buy licensed school supplies.With so much marketing around us, it can be tough to stop the tide.
"One thing that helps parents'is that they can talk to other parents about, this kind of thing," Linn suggested ."If you decide you want to buck this, it helps to find other people who will do the same thing .That way, if your child says."Everyone's doing it," you can really have a sense of whether everyone is." |
