An electric eel can produce a shock of more than 600 volts， 3 times more powerful than a household outlet. It not only uses this power to kill its prey but to locate it as well-though it is born with eyes， it is blind as an adult and employs its electricity to find food in much the same way as man uses radar.
電鰻能釋放出超過600伏的電，是家用電燈電流的3倍。他不僅用這一電力殺死獵獲物，還用它尋找獵物。電鰻雖然出生時有眼睛，長大后會變成瞎子，它像人使用雷達那樣通過放電尋找食物。
A factory in which 2，000 different machines are operating with twenty-five men on each machine would rightly be considered a complex structure. The smallest bacterium is that complex. In effect， there are 50，000 chemical reactions taking place in each bacterium.
如果一個工廠有2，000臺不同的機器，每臺機器有25個人操作，這樣的工廠可被認為是一個綜合體。最小的細菌就是這樣一個綜合體。事實上，每個細菌在發(fā)生這5萬個化學反應(yīng)。
In a beehive， only 1.5 ounces of wax are used to build a comb that will hold 4 pounds of honey.
在蜂巢中，僅用1.5盎司的蜂臘造的蜂房可以盛下4磅蜂蜜。
“Flower clocks” provided a unique and decorative means of telling time in the formal gardens of nineteenth-century Europe. A series of flowers beds was laid out to form a clock face， with each bed representing a daytime hour. The beds were planted with flowers known to open or close at the prescribed hours. On a sunny day， the time on a flower clock could be determined to within a half-hour.
19世紀歐洲正規(guī)的花園里的“花卉鐘”以其獨特的裝飾性的方式告訴人們時間。人們將各種不同的花卉種成一個一個鐘面，每個花床代表白天一個鐘點，花床上種植著預計在某一時間開放或閉合的花。晴天時，可根據(jù)花卉鐘判斷時間，誤差不超過半個小時。
