下列区间是函数的一个减区间的是( ) A. B. C. D. 答案:B 解析:得,故选。“If you talk to the plants, they will grow
faster and the effect is even better if you’re a woman.” Researchers at Royal
Horticultural Society carried out an experient to find that the voice of a
woman gardener makes plants grow faster.
The experiment lasted a month and by the
end of the study scientists managed to discover that tomato plants grew up two
inches taller when women gardeners talked to them instead of male.
Sarah Darwin was the one making the plants
registered the best growth. Her voice was the most “inspiring” for plants than
those of nine other gardeners when reading a passage from The Origin of
Species. The great-great-granddaughter of the famous botanist(植物学家) Charles Darwin found that
her plant grew about two inches taller than the plant of the best male
gardener.
Colin Crosbie, Garden Superintendent at
RHS, said that the finding cannot yet be explained. He assumes that women have
a greater range of pitch(音高) and tone(音调) which might have a certain effect on the sound waves that reach the
plant. “Sound waves are an environmental effect just like rain or light ,”said
Mr Grosbie.
The study began in April at RHS Garden
Wisley in Survey. Scientists started with open auditions(听力) for the people who were
asked to record passages from John Wyndham's The Day of the Triffids,
Shakespeare’s A Midsummer's Night Dream and Darwin's The Origin of Species.
Afterwards researchers selected a number of
different voices and played them to 10 tomato plants during a period of a
month. Each plant had headphones(耳机) connected to it. Through the headphones the sound waves could hit
the plants. It was discovered that plants that “listened” to female voices on
average grew taller by an inch in comparison to plants that heard male voices.
Miss Darwin said, “I think it is an honor
to have a voice that can make tomatoes grow, and especially fitting because for
a number of years I have been studying wild tomatoes from the Galapagos Island
at the Natural History Museum in London.”
