阅读下面的材料,从方框中所给的A—E五个选项中选出正确的选项(其中有一项为多余项),将其序号填入第31—34小题,并回答第35小题。
Have you ever made a simple musical instrument? You can do this with things around you, such as glass bottles. It's very easy and a lot of fun. Why not give it a try?
What we need: Five empty glass bottles, cups or jars, water, a spoon
Step 1 Fill each bottle, cup or jar with a different amount of water. 31.
Step 2 Put the water bottles on a table. Arrange(排列) them from the lowest water level to the highest. Then, tap each bottle with the spoon or another striker. 32.
Step 3 Try changing the water levels in your bottles to change the pitch(音高). Pitch is how high or low a sound is. See if you can tune your bottles. 33.
How it works: 34.
A. Anyone can play the instrument.
B. Don't fill any of them over halfway.
C. Which ones make the higher sounds?
D. Can you turn these sounds into a song?
E. Sounds are made when things shake or move quickly.
35. Would you like to try making a musical instrument? Why?

How it works: 34.
E
The pitch sound depends on the speed of the moving. When you tap an empty bottle, it moves quickly and makes a high-pitched sound. When you add water, the bottle becomes heavier and moves slower. Therefore, the less water, the higher the pitch; the more water, the lower the pitch.A. Anyone can play the instrument.
B. Don't fill any of them over halfway.
C. Which ones make the higher sounds?
D. Can you turn these sounds into a song?
E. Sounds are made when things shake or move quickly.
35. Would you like to try making a musical instrument? Why?
One possible version: Yes. Because it’s interesting to make a simple musical instrument.
