4月28日,我放学以后在教七楼后的小池塘里抓了11只蝌蚪。小蝌蚪长着圆圆的脑袋和长长的尾巴,可爱极了。大的蝌蚪大概有3cm,小的只有2cm。我问科学老师:蝌蚪需要多久才能变成青蛙?她告诉我需要一个多月,就是30多天。可是我的同学韩嘉康却说,需要一年或者半年才能长成青蛙。我决定天天观察它们,看到底是谁说的对。 On April 28, I caught 11 tadpoles in the small pond behind the seventh floor after school. Small tadpoles with round head and long tail, very cute. Large tadpoles about 3cm, small only 2cm. I asked the science teacher: How long does it take for a tadpole to become a frog? She tells me it takes more than a month, which is more than 30 days. However, my classmate Han Jiakang said that it takes a year or six months to grow into a frog. I decided to observe them daily and see who is right.
