              There’s no such thing as living alone. Never mind if you’re   (1)   only person in your house and have no dog, no cat, not even fish. You still have got several billion   (2)  (roommate) — and so do we all. Some of them are harmless, some are   (3)  (actual) helpful and some could even kill you. They are, of course, bacteria, fungi(菌类) and viruses, and like it or not, they’re on you, around you, and deeply within you. The fact that bacteria life is everywhere is not   (4)  (surprise). It’s something you    (5)    (learn) from your childhood when your mother told you not to drink water from someone else’s glass. There are lots of bacteria   (6)   are living in your tea kettle.

              A scientist, living in France twenty years ago,   (4)   (write) about what he called the “Mozart Effect”. He said that   (5)   could be helpful to the brain when listening to the classical music of Mozart. Some researchers said that Mozart’s music would make you much   (6)   (smart), or even have some health disorders   (7)   (cure). Others said that there was nothing special about Mozart’s music. Any kind of high energy music would work. So if the cost of a musical instrument or music lessons is too costly, can we get   (8)  same brain experience just by listening?

              Usually people have teachers, or they can teach themselves music.   (9)   , the point is that they’re actively playing a musical instrument and engaging in making music instead  (10)   listening to music passively.
