我要一篇关于描述听觉的英语文章

Sound waves acting on the hearing organs, so feel excited and cause the auditory nerve cells, the impulse to release the incoming information, by all levels of auditory sensations caused by the analysis. Hearing is second only to the important sense of the visual channel. It is in man's life played a significant role.External ear canal sound waves transmitted through the media, and then reached the tympanic membrane. Tympanic membrane vibration transmitted through the inner ear ossicles, the cochlea to stimulate the ciliated cells arise within the nerve impulses. Nerve impulses along the auditory nerve auditory cortex reached the center to form a hearing.

The sound source - auricular (collection acoustic) - the external auditory canal (to sound through) - tympanic membrane (to convert sound waves into vibrations) - Cochlear (to convert vibrations into nerve impulses) - the auditory nerve (impulse transmission) - the brain auditory Hub (the formation of hearing)

Sound waves reach the eardrum through the external auditory canal, tympanic membrane caused by vibration. Tympanic membrane vibrations through the auditory ossicles but also conveyed to the vestibular window (oval window), so that vestibular membrane transfer window, caused by vestibular first-order foreign lymphatic vibration, and thus in the endolymphatic cochlear duct, basilar membrane, spiral, etc. have taken place in the opposite vibration .

At the junction of the cochlear nucleus, the replacement neurons (second-class neurons), the issue of the composition of fiber transverse to the contralateral trapezoid body, upward in the brain via the exchange of inferior colliculus neurons (third level neurons) cochlear endolymphatic vibrations occur caused hearing, called bone conduction. Bone conduction extremely sensitive to sound the feelings of normal people mainly rely on air conduction.

Responsible for external and middle ear sound conduction the role of the lesions occur in these areas caused by hearing loss, known as conductive hearing loss, such as hearing loss caused by chronic otitis media. Parts of the inner ear and the auditory nerve lesions caused by hearing loss. Known as nerve deafness. Certain drugs such as streptomycin can damage the auditory nerve caused by tinnitus, deafness, so be careful when using these drugs.

Under normal circumstances, the auditory stimulation is the appropriate frequency to 16 - 20000 times / sec (Hz) sound waves, also known as audible sound. However, different ages, their hearing is not the same scope. For example: a child can hear 30000 - 40000 Hz sound waves over the age of 50 can only hear 13,000 Hz sound waves. Most people below 16 Hz and 20,000 Hz sound waves above, it is difficult to hear. When the sound intensity over 140 db, the sound is no longer cause hearing, but the tenderness perception.声波的听觉器官采取行动,因此感到振奋,并导致听觉神经细胞,释放的冲动,传入的信息,通过分析所造成的听觉感受各级。听觉是仅次于视觉通道的重要意义。它在人类的生活发挥了重要作用。

外耳道声波通过媒体传播,然后到达鼓膜。鼓膜振动传播途径是内耳小骨,耳蜗刺激纤毛细胞内的神经冲动产生。沿听神经听觉皮层达成的中心,形成听觉神经冲动。

声源 - 耳廓(收集声波) - 外耳道(健全通过) - 鼓膜(转化为声波振动) - 耳蜗(转换成神经脉冲振动) - 听神经(脉冲传输) - 的脑干听觉中枢(形成的听证会)

通过声波到达外耳道鼓膜,鼓膜的振动造成的。通过听骨鼓膜振动,而且还转达前庭窗(卵圆窗),使前庭膜的转会窗口,由前庭阶外淋巴振动造成的,因此在耳蜗内淋巴管,

基底膜,螺旋等采取相反的振动位置。

在耳蜗核交界处,更换神经元(二等神经细胞),在横向的纤维组成问题向对侧梯形机构,在大脑通过向上劣势(第三级神经元)耳蜗内淋巴丘神经元交流振动发生的造成听觉,称为骨传导。

骨传导声音极为敏感,对一般人的感情,主要是靠空气传导。

外部和中耳的声音传导作用的负责任的病变发生在听力损失的传导性听力损失,如慢性中耳炎引起的听力损失,已知,造成这些地区。内耳的部件和听觉神经听力丧失所引起的病变。被称为神经性耳聋。

某些药物如链霉素可损害听觉神经的耳鸣,耳聋,在使用这些药物所以要小心引起的。

在正常情况下,听觉刺激,是适当的频率为16 - 20000次/秒(赫兹)的声波,也被称为可听见的声音。但是,不同的年龄,他们的听力是不一样的范围。例如:一个孩子能听到30000 - 超过50岁4.0万赫兹的声波只能听到13,000赫兹的声波。低于16赫兹和20大多数人,

000赫兹以上的声波,很难听到。当超过一百四分贝声强,声音不再是事业的听证会,但温柔的看法。

Dear Zhang Hua,

It’s three months since I heard from you last time. Now I want to tell you an impressive story happened on my first lesson.

On hearing the bell, students ran into the classroom as quickly as they can. But a boy, Li Ming, whose father died a month ago, was late for the class. He stood outside the classroom, silently. I smiled to him and let him came in. After a while, he cried on his desk. Then I walked to him and asked what had happened .He told me that his mother was ill and he had to take some medicine for her. At the same time, he apologized to me for his lateness. Moved by his words, I praised him for his deeds and decided to sing a song named “Mother” for the students. How time flies! Class was over before I realized it.

From the story I felt we should respect our parents and do our best to help them. Do you think so? I’m looking forward to your reply.

Yours truly,

Li Hong

有没有人帮我写一篇关于讨论英语听力的作文要英文的哦

Hearing the importance of not self-evident, students should raise the level of hearing, first of all, a solid foundation in grammar and vocabulary certain; Second, we must pay attention to the following questions:

1. Change the traditional way of word memory

Most of the students word memory is the traditional way, simply by writing spelling words in mind. Remember the written spelling, listening, Gendu and repeatedly read out is very necessary, on the one hand guarantee the correct pronunciation, on the other hand, can be heard familiar words.

2. Attention and often read aloud

And often read aloud to contribute to the hearing.

3. Jing and Fan Ting listen to combine

There are two advantages of fine listening to: (1) can focus on the promotion (2) to raise the awareness level of language forms, and details that do dictation, can improve the correct rate. At the same time, we can not focus only on fine listen to the neglect of the Fanting. Through Fanting not only can get more information and knowledge, but also help to improve the tone of voice, listening to expand vocabulary.

4. Listening material diversification

We all know that to raise the level of hearing only 1-2 per week of listening class is not enough, in extra-curricular will take the initiative to find some material to practice hearing, but many people in the hearing of non-selective, or just personal preferences Listening materials, such things are often reactive and a half times, although spent a lot of time, but little progress.

听力的重要性不言自明,学生应提高听力水平,首先,要有扎实的语法基础和一定的词汇量;其次,要注意以下几个问题:

1.改变传统的单词记忆方式

大部分学生单词记忆的方式是传统的,单纯地通过书面拼写记单词。记住书面拼写的同时,听音、跟读乃至反复朗读是非常必要的,一方面保证了读音正确,另一方面,可以听熟单词。

2.重视并经常朗读

重视并经常朗读有助于提高听力水平。

3.精听和泛听相结合

精听有两点好处:(1)可以促进注意力集中;(2)提高对语言形式的意识程度,在做听写和细节题时,可以提高正确率。同时,也不能只注重精听而忽视了泛听。通过泛听不仅可以获得更多的信息和知识,还能有助于提高语音语调,扩大听力词汇量。

4.听力材料多样化

大家都知道要提高听力水平只靠每周1-2节听力课是不够的,在课外都会主动地找一些听力材料来练习,但是,很多人对听力材料不加选择,或只凭个人喜好选择听力材料,这样往往事倍而功半,虽然花了很多时间,但是进步不大。

关于提高英语听力和口语的英语作文带翻译 120字左右

Learning English just like learning any other foreigh language, is hard work so you should spend time practicing using English for communication. Besides, you should listening to English radio programmes and attending English debbates and speech contests. What's more, be patient and confident. Don't be shy and don't be afraid of making mistakes. We must understand that mistakes are unavoidable. A saying goes" Failure will blossom into success." So be patient with your mistakes and try to awoid them other time. I believe" practice makes perfect". So why not try to speak English as often as you can.
