38. 高血压实验
一组实验,二组人都有高血压,一组屏住呼吸,一组大声朗读。结果发现朗读的血压降得要比正常的多,所以研究人员推出,大声朗读是治疗高血压最好方法。evaluate
我选的是,应该知道比较血压在大声朗读和屏住呼吸后,哪个会更快升高。

39. 企鹅
The number of A* penguin decrease significanly during the hundreds of years. Less heavy isotype than light in their body. The more heavy isotype in animals body, the higher in the food chain they are. This indicates a shift from fish to K. Penguins' predator whale, sharp also decrease greatly. The shift from fish to K must result from the decline in whale and shark. ——by liberzephyr(V37) |
