For college students, acquiring reading comprehension ability plays an essential part in understanding cultural distinctions and communicating effectively. However, the truth is that their reading comprehension ability and language applying competence prove not very optimistic. Therefore, the Present paper gives some insight to teachers on how reading English should be taught more effectively to college students.展开更多

The tracheas of adult rats were obtained by autopsy within 30 minutes after death and placed into a modified Hank’s solution. The experiments were performed on the large branches of the rat bronchi following entry into the lung. At the terminal level of the airway, no cartilage segments were seen. The muscle layer was prepared by careful removal of the connective tissue, cut into small pieces (1 mm3), and dispersed enzymatically (collagenase, elastase) into single cells. Freshly isolated cells could be used the same day. The small muscle pieces and isolated cells were cultured in the modified Hank’s or modified Eagle’s medium with 5% CO2 at 37℃ .展开更多
