Question

【題目】

People, animals, and other things make sounds (聲音).

Sounds can be loud (大聲的) or quiet, happy or unhappy.

Sounds are very important. Most people and animals use sounds, to communicate (交流) with each other. Many things also make useful sounds. Drums (鼓) and pianos bring us music. Bells in school tell us to have classes on time.

What is sound? Well, there is sound when an object (物體) vibrates (震動), or moves (移動) back and forth very fast. A vibrating object makes the air around it move. This is how sound travels. For example, when a driving car passes by, the air around it vibrates. When the vibrating air gets to your ear, you hear the sound of the passing car. We call the vibrating air sound waves (聲波).

There are different kinds of sounds. Some sounds are loud. Others are quiet. The loudness of sound is called volume (音量). Very loud sounds are bad for your ears. Be careful around loud sounds. Cover your ears with your hands when you hear them, or move away from the loud sounds. When you use earphones to listen to music, make sure it is not too loud.

Sounds are everywhere in our life. Enjoy the sounds of the world and be careful with your ears!

【解析】

短文大意：本文是科普類閱讀，介紹了聲音的重要性、傳播途徑和分類，指出聲音在我們的生活中無處不在，要享受世界的聲音，愛護我們的耳朵。

【1】題意：聲音是非常重要的，因為大多數(shù)人和動物都用聲音交流。
考查細節(jié)判斷。A. 大多數(shù)學(xué)生在學(xué)校有音樂課。B. 大多數(shù)孩子喜歡彈鋼琴和打鼓。C. 大多數(shù)人和動物用聲音交流。根據(jù)“Sounds are very important. Most people and animals use sounds to communicate with each other聲音是非常重要的。大多數(shù)人和動物用聲音互相交流”，可知選C。

【2】題意：聲音是如何傳播的？
考查細節(jié)理解。根據(jù)“there is sound when an object vibrates, or moves back and forth very fast. A vibrating object makes the air around it move. This is how sound travels當一個物體振動或快速前后移動時，會有聲音。一個振動的物體使它周圍的空氣運動。聲音就是這樣傳播的”，可知An object vibrates and makes the air around it move（一個物體振動并使它周圍的空氣運動）符合題意，故選C。

【3】題意：我們能從這篇文章中了解到什么？
考查細節(jié)判斷。A. 非常安靜的聲音對你的耳朵不好；根據(jù)“Very loud sounds are bad for your ears”可知說法錯誤。B. 當我們聽音樂時，把音量調(diào)低；根據(jù)“When you use earphones to listen to music, make sure it is not too loud”可知說法正確。C. 不同的聲音有相同的音量；根據(jù)“There are different kinds of sounds. Some sounds are loud. Others are quiet”可知說法錯誤。綜合以上分析，故選B。

本文介紹了聲音的重要性、傳播途徑和分類，通俗易懂。題目涉及細節(jié)理解和判斷，考生認真閱讀原文，注意細節(jié)對照，即可選出正確答案。例如小題1，問聲音為什么非常重要，考查細節(jié)判斷；根據(jù)“Sounds are very important. Most people and animals use sounds to communicate with each other聲音是非常重要的。大多數(shù)人和動物用聲音互相交流”，可知most people and animals communicate with sounds符合題意，故選C。
