Question

Have you ever tried making music with glasses or bottles filled with water? I bet your favorite band hasn’t. Experiment with your own special sounds by turning glasses of water into instruments, make some cool music and find out how it works.

What you’ll need:

Five or more drinking glasses or glass bottles. Water. Wooden stick such as a pencil. If possible, you’d better do it in a small but empty room with a long table in.

Instructions:

Line the glasses up next to each other and fill them with different amounts of water. The first should have just a little water while the last should be almost full, and the ones in between should have slightly more than the first.

Hit the glass with the least amount of water and watch the sound, then hit the glass with the most water, which makes the higher sound?

Hit the other glasses and see what noise they make. See if you can get a tune going by hitting the glasses in a certain order.

What’s happening?

Each of the glasses will have a different tone when you hit with the pencil. The glass with the most water will have the lowest tone while the glass with the least water will have the highest. Small vibrations (震动) are made when you hit the glass, and this creates sound waves which travel through the water. More water means slower vibrations and a deeper tone.

1.What’s needed in the experiment according to the passage?

A. Five bottles of water.    B. Seven drinking glasses

C. A big and empty room.    D. A pencil and a wooden stick.

2.According to the passage , the purpose of the experiment is to get __________.

A. a tone.    B. a tune.    C. some vibrations.    D. some water

3.Which glass can have the lowest tone when you hit it in the experiment?

A. The one with no water.    B. The one with the most water.

C. The one with the least water.    D. The one with half of the water.

4.Where is the passage the most likely to come from?

A. A Travelling Guide    B. A Child Novel

C. A Fashion Magazine    D. A Music Textbook.

【解析】本文叙述了一个关于音乐的实验。用玻璃瓶子装不同数量的水，然后用小棍来敲击，看不同的瓶子发出音调的高低。

1.细节理解题。根据Five or more drinking glasses or glass bottles.可知，需要5个或更多的饮水的玻璃杯或玻璃瓶。故选B。

2.细节理解题。根据See if you can get a tune going by hitting the glasses in a certain order.可知，实验的目的是得到的曲调。故选B。

3.细节理解题。根据The glass with the most water will have the lowest tone装水最多的那个瓶子发出的音调最低。故选B。

4.推理判断题。根据短文的内容叙述的是用玻璃瓶子装不同数量的水，然后用小棍来敲击，看不同的瓶子发出音调的高低。这里是关于音乐方面的，所以有可能来自音乐课本。故选D。

点睛：推理判断题主要考查学生透过文字表层信息，根据上下文逻辑关系进行推理、分析，挖掘文章的真正内涵，推断出材料中没有直接交代，而需要加以阐述的概念与结论。包括推断隐含意义、推断下文内容、猜测作者态度等，属较高层次的阅读。推测短文的出处，主要看短文的内容。
