保护生物多样性最为有效的措施是（    ）

    "Early to bed, early to rise makes people healthy, wealthy(富有的)and wise(聪明的). "

    This is an old English saying. Children should have ten hours' sleep every night, or they can't do their work very well. They will not be wise, either. The body needs exercise. Walkin9, running, swim-ruing and playing ball games are all exercise. Exercise keeps the body strong and makes the mind bright.

阅读下面一首宋词，完成下面小题。

早秋山中作

【唐】王维

无才不敢累明时，思向东溪守故篱。

岂厌尚平婚嫁早，却嫌陶令去官迟。

草间蛩响临被急，山里蝉声薄暮悲。

寂寞柴门人不到，空林独与白云期。

【注】①这首诗疑作于王维四十多岁的时候，过着半官半隐的生活。②尚平，字子平，东汉朝歌人。为子嫁娶毕，即不复理家事。后用为不以家事自累的典实。③蛩，蟋蟀。
