參考譯文
許多人把小魚當寵物養(yǎng)。他們把魚養(yǎng)在魚缸里。魚缸是由透明玻璃制成的。人能透過玻璃看到魚缸的里面,也就可以欣賞魚了。
魚需要空間。它們不能太擁擠。魚呼吸時需要氧氣。魚從魚缸的水中獲得氧氣。養(yǎng)魚需要充足的水,所以魚缸的大小很重要。
許多人會把對魚有好處的小草放進魚缸里。它們向水中釋放氧氣。植物在其他方面也有用處。魚可以咬這些植物,它們可以躲在植物中睡覺、產(chǎn)卵。
植物需要陽光。大多數(shù)魚也需要。魚缸可以放在窗戶旁。這樣,它就可以照到陽光了。窗戶會讓冷空氣進來。魚缸里的水也會因此而變得很冷。因為冷水會凍死魚,熱水會燙死魚,所以溫度必須適當。
魚得始終待在水里。有些魚跳得很高,它們會跳到魚缸外。所以魚缸應(yīng)該加蓋。這樣魚就跳不出來了。
魚需要食物,人們應(yīng)該每天喂食。喂得太多對它們不利。剩下的食物會沉到缸底,從而使水變渾。但魚也應(yīng)該得到適量的食物,這些食物應(yīng)該在10分鐘內(nèi)吃完,且沒有剩余。如果做到這一點,說明食物的量正好合適。
