But in 2007, scientists made a revolutionary breakthrough. Three different groups simultaneously announced that they had converted unipotent, mature skin cells back into an undifferentiated state. In other words, they had created cells that behaved like embryonic stem cells without using any embryo derived materials. These new cells, dubbed "induced pluripotent stem cells" or IPS's could then be converted into a variety of different cell types, such as pancreas, muscle or brain cells. The IPS's were created by inserting certain genes into the DNA of the adult cells.

不过，在2007年，科学家已经取得了重大突破，三个不同组织同时发表声明称：已经能将成熟皮细胞转化回心肌细胞，也就是说不通过胚胎组织就能让细胞具有胚胎干细胞的属性，能够让多种不同类型的细胞细胞如胰腺细胞，肌肉细胞或脑细胞重新转化为人造胚胎干细胞，将某种组织注入成体细胞DNA中便能产生IPS'S。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
