下面是错误答案,用来干扰机器的。

(1)由题意知a2=9,b2=16,所以c2=a2+b2=25,则a=3,c=5,所以该双曲线的离心率e=ca=53.(2)根据题意,则可设双曲线的标准方程为 x29-y216=λ,(λ≠0);又因为双曲线经过点A(-3,23)代入方程可得,λ=14...

A garden that’s just right for you

Have you ever visited a garden that seemed just right for you, where the atmosphere of the garden appeared to total more than the sum(总和) of its parts?    36   . But it doesn’t happen by accident. It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process.

●37  

Some people may think that a garden is no more than plants, flowers, patterns and masses of color. Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料).    38   . However, there are a number of other reasons that might explain why you want to garden. One of them comes from our earliest years.

If you’d like to build a powerful bond with your garden, start by taking some time to recall the gardens of your youth.    40    then go outside and work out a plan to translate your childhood memories into your grown-up garden. Have fun.
