How does the professor develop the topic of the violin family? Choose two answers. [br]
Questions 1 through 5. Listen to part of a lecture in a music theory class. The professor is talking about the violin family.
The string section of an orchestra is made up of four instruments that are very different in size and range of pitches. These four instruments are the violin, viola, cello, and double bass. They are often grouped together and called the violin family. Think of violas, cellos, and double basses as just larger-sized violins. The strings on these instruments are longer, thicker, or heavier, and they play lower notes than the violin does. However, all the members of the violin family are built and played in basically the same manner.
Reduced to its basics, a stringed instrument of the violin family is simply two bows rubbed together, but one of the bows has a sound box attached. Each member of the violin family has four strings that are stretched across a wooden box. You play all of these instruments by scraping the strings with the bow, which causes the strings to vibrate.
Let’s take a closer look at the violin and how it produces sound. Notice that the strings are stretched over this upright piece of light-colored wood. The piece of wood is called the bridge. When the violin is played, the vibrating strings cause the bridge to vibrate. The bridge has a design carved in it, a design that helps the wood to shake back and forth freely in rapid vibrations. The bridge sends the vibrations to the top, or belly, of the violin. Since the belly is much larger than the bridge, it causes more air to vibrate, making the sound louder.
But even the vibrating belly of the violin does not by itself make a very loud sound. The sound grows because the wood makes the air inside the violin vibrate. Imagine you’re standing in a room with mirrors on all the walls. Your image is reflected back and forth, and you can see yourself lots of times. In the same way, the violin’s specially shaped sound box reflects the sound waves back and forth, making them stronger and louder. The violin’s characteristic shape amplifies the sound vibrations. Finally, the vibrations emerge even louder through the two f-shaped sound holes in the belly. By that, I mean they look sort of like lower case letter Fs.
1. How does the professor develop the topic of the violin family?
2. What point does the professor make about the instruments in the violin family?
3. How do the other members of the family differ from the violin?
4. Listen again to part of the lecture. Then answer the question. "Imagine you’re standing in a room with mirrors on all the walls. Your image is reflected back and forth, and you can see yourself lots of times. In the same way, the violin’s specially shaped sound box reflects the sound waves back and forth, making them stronger and louder."
Why does the professor mention a room with mirrors on all the walls?
5. The professor briefly explains what happens when a violin is played. Indicate whether each sentence below is part of the process.

B、They play a lower range of notes.
C、They are made of different kinds of wood.
D、They are not part of a typical orchestra.
