初夏的早晨,我迎着朝阳走进农民技术员精心莳弄的棉田,一株株棉苗水灵灵、绿油油,葱笼茁壮,长势喜人。忽然,一阵可怜而轻微的呼声吸引了我。“救救我吧,血液都快被吸干了。”我循着声音看去,发现相邻的棉田里一株株叶片卷曲、茎叶瘦弱的棉苗正在低头抽泣。仔细再看,棉叶的背后一群群吸血鬼——棉蚜正在狠命地吸吮着棉苗的汁液。这可怎么办呢?难道眼看这可爱的棉苗被活活扼杀而不管吗！ In the early summer morning, I walked into the cotton field where peasant technicians carefully scrambled for the sunrise, and a strain of cotton seedling water was spirited, green and chopsticks grew vigorous. Suddenly, a poor but slight voice caught me. “Help me, the blood is almost sucked dry.” I looked at the sound and found that the leaves of a neighboring plant were curled, and the thin cotton plantlets were sobbing. A closer look, a group behind the cotton leaf Vampire - cotton aphid is fiercely sucking cotton seedlings juice. This can be how to do it? Do you see this cute cotton seedling is killed live regardless of it!
