青果微点评:这是一篇探究类的作文,自然要先设悬念,在情节上加以设计,生活中有许多自然现象无不深藏奥妙,人是有好奇之心,自然会跟着你读下去。我胡乱地将一堆鸡蛋放入水中,一不小心把昨天煮熟的一枚鸡蛋也扔了进去。我刚想用手去捡,忽然又停下了,因为我发现了一个奇怪的现象,在许许多多的生鸡蛋中,那枚熟鸡蛋有些不同:生鸡蛋静静地沉在水底,而熟鸡蛋则悠然自在地漂浮在水面上。 Green fruit micro comments: This is an exploration of the composition of the essay, nature must first suspense, in the plot to be designed, there are many natural phenomena in life all deep hidden mysteries, people are curious, will naturally follow you to read. I casually put a pile of eggs into the water, accidentally thrown into an egg cooked yesterday. I just wanted to pick it up with my hand and suddenly stopped again because I found a strange phenomenon that the cooked egg was a bit different among so many raw eggs: Egg is leisurely floating on the water.
