在声音传递给大脑的整个过程中,任何部分发生障碍,人都会失去听觉,但如果只是传导障碍,例如______损坏,而______没有损坏,则可以利用______传导来听到声音.

答案

在堵住耳朵的时候,人就无法通过耳朵去感知声音,这时候人听到的声音是通过头骨、颌骨等骨骼传播到听觉神经,然后由听觉神经传给大脑的,此种听到声音的方式被称作骨传导,助听器就是利用了骨传导的原理;

在声音传递给大脑的整个过程中,任何部分发生障碍,人都会失去听觉,但如果只是传导障碍,例如耳膜(听小骨)损坏,而听觉神经没有损坏,则可以利用骨传导来听到声音.

故答案为:耳膜(听小骨);听觉神经;骨.

Zhang Lili, a 29-year-old middle school teacher at the No 19 middle school in the city of Jiamusi in Northeast China's Heilongjiang province was crossing the road just outside the school's gate when a school bus suddenly came rushing toward nearby students at 8:38 pm on May 8, 2012.

"There were three buses at the school gate ready to pick up students, but the one in the back suddenly crashed into the second bus and pushed it into the first one. There were several students standing between the first and the second buses and they were about to be crushed," said Liu Ye, a student of No. 19 middle school.

"We were waiting to board the bus when suddenly it began moving toward the teachers and students. Zhang Lili immediately pushed the students out of the way, but unfortunately she didn't escape. The bus crushed her legs. " added Liu.

Zhang Lili was sent to hospital at about 9 pm and she was critically injured and her blood pressure was low. The situation was quite serious when rushed to hospital.

After consulting specialists, the doctors decided that the only way to save her life was cut off both of her legs.

Upon learning about the accident, the deputy mayor of the city, Sun Zhe, asked the hospital to "save the young teacher regardless of the cost"  

"If necessary, we will invite more specialists from the capital city, even from whole nation," said Sun.

Fortunately, after 58 hours of emergency medical attention after being transferred to the First Affiliated Hospital of Harbin Medical University, Zhang finally regained consciousness on May 15.

"Her courage moved all of our staff, and we will try our best to help the brave teacher in her future life. " said Wang Jianwei, the director of center.
