根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多于选项。

小题1: Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.

Some scientists believe that birds do sing some of the time just because they are happy.

However, they sing most of the time for a very different reason. 小题2:  Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims as its own. 小题3: . No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting season. So he is screaming all the time, whether he can see an outsider or not. 小题4: 

Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language all their own. 小题5:

A．Only he and his family are welcome there.

B．Most of it has to do with attracting mates and setting up territories.

C．Have you ever heard birds sing?

D．Their singing is actually a warning to other birds to stay out of their territory.E. Have you ever wondered why birds sing?

F. Most of the language is widely used.

G. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

     As a music teacher for twenty-seven years, I have always known that music touches the soul. It can break

through all kinds of barriers to reach students in a very special way. It can be the means for each child to find

their light.

     A few years ago, I was blessed with the opportunity to teach pre-school students one afternoon a week.

One of my most memorable students was Vanessa. She was five years old, had difficulty walking, and could

not speak. We mostly sat on the floor for our music lessons and Vanessa liked to sit on my lap.

     One of her favorite songs was John the Rabbit. It was a call and response song where I sang the call and

the students clapped two times while singing the repeating phrase,"Oh, yes!" Vanessa liked to put her hands

together with mine and clap with me. We performed that song during every class, Vanessa and I clapping

together. She never said or sang a word.

     One day late in the school year, when the song was finished, Vanessa turned around, looked me in the eye,

clapped her tiny hands two times and said the words "Oh, yes!" I opened my mouth and for that moment I was

the one who could not speak. Through music, we had made a connection. Several years later, I came across

Vanessa on the street in town. I stopped my car and waved to say hello. She waved back with a big smile on

her face and then clapped her hands two times, mimicking (模仿) the song we had performed in our music

class. This precious little girl, through her connection with music, left an impression on me that will last

forever. Every child has the ability to learn and grow. It is up to us educators to discover the way to reach each and every one of our students. We all must find each child's light.
