Question

【題目】

At night, you fall asleep while listening to beautiful music.【1】You can enjoy all of these things because of one important organ (器官) — the ears. March 3 is Ear Care Day. It helps us remember the importance of our ears and encourages us to take good care of them.

You may wonder: how do the ears work? The ear has three different parts: the outer ear, the middle ear, and the inner ear, The outer ear is the part you can see.【2】The sound then travels down to middle ear, the inner ear and then to your brain.

【3】Your ears keep on hearing sounds, but your brain just ignores them. That’s why you may sometimes wake up suddenly in the middle of the night — your brain heard something, but you don’t know what it was, since you were asleep.

But ears do more than hear.【4】In the inner ear, there are organs that are filled with liquid and covered in small hairs. When you move your head, the liquid and hairs move, too. They send messages to your brain about the position (位置) of your head.

More surprisingly, ears even help with tasting food.【5】But there are nerves ( 神經(jīng)) running through the middle ear that connect the tongue to the brain.

The ears are truly important organs with many functions (功能). Everyone should make sure to protect their own ears as well as they can.

【解析】

本文詳細(xì)介紹了耳朵的結(jié)構(gòu)，以及告訴我們耳朵是重要的器官，有很多功能，所以人們應(yīng)該盡可能地保護(hù)自己的耳朵。

【1】根據(jù)前文At night, you fall asleep while listening to beautiful music“晚上，當(dāng)聽著優(yōu)美音樂的時候，你會睡著”，以及下文You can enjoy all of these things because of one important organ“因為一個重要的器官——耳朵，所以你可以享受到這些所有的事情”，可知，耳朵是很重要的器官，在晚上聽著優(yōu)美音樂的時候睡著，相對的在早上也可以被窗外的鳥兒叫醒，所以此空處填In the morning, you are woken up by the singing of birds outside。故選C。

【2】根據(jù)前文The outer ear is the part you can see“外耳是你可以看到的那部分”，及The sound then travels down to middle ear“然后聲音會傳播到中耳”，可知，此空處是描述外耳的作用是收集周圍的聲音，所以空格處填It collects sound around you。故選E。

【3】根據(jù)下文Your ears keep on hearing sounds“你的耳朵一直在聽聲音”，可知，即使你睡著了，你的耳朵也不會停止工作，所以空格處填Your ears never stop working, even when you are asleep。故選B。

【4】根據(jù)下文In the inner ear, there are organs that are filled with liquid and covered in small hairs… of your head“在內(nèi)耳，有充滿液體和覆蓋炸小毛發(fā)的器官。當(dāng)你搖頭時，液體和小毛發(fā)也會移動。他們會向你的大腦發(fā)送關(guān)于你頭顱位置的信息”，可知，耳朵也會起到平衡的作用，所以空格處填They help you keep your balance, too。故選D。

【5】根據(jù)上文More surprisingly, ears even help with tasting food“更令人驚訝地是，耳朵甚至能幫助品嘗食物”，及下文But there are nerves running through the middle ear that connect the tongue to the brain“但是中耳有連接舌頭和大腦的神經(jīng)”，可知，實際上我們不是用耳朵品嘗食物，而是因為中耳有連接舌頭和大腦的神經(jīng)，所以此空處是補充說明實際上我們不是用耳朵品嘗食物，故填Of course, you don’t actually taste food with your ears。故選A。
