【简答题】
(B) My dad also taught me,by example,that a healthy lifestyle is important.He was hardly ever sick.But I don’l think my dad ever even had a cup of coffee.He barely touched alcohol. He would say,“Boonnie,your voice is a reflection of your overall physical well-being.So if you want to sing well,take better care of yourself.” If I became hoarse(嘶哑)or caught a cold,he didn’t blame me directly:“Well,Bonnie,you know,if you’d get to sleep a little earlier,that would probably be a good idea.”When I decided to get unexcitable about 18 years ago,he told me.“See, Bonnie,it's so great to see you in such strong voice all the time.” He just did not complain,even when he was uncomfortable toward the end,from the pneumonia that eventually took his life.He simply made a choice to be positive and not negative. I am so glad that we had the chance to perform together.I was touched that he tried singing my music,even though the bluesy style didn’t come naturally to him.Then,when I had so much Grmnmy success with my album Nick of Time in 1990,I realized. Hey,I have one of the greatest singers of all time in my family.I was very nervous about doing the Boston Pops show on TV with my dad.To calm me,he said,“Bonnie,a beautiful song is a beautiful song.Just believe it.”I looked in my dad’s eyes,and there we were singing the Irving Berlia song with the lvric.Of all the duets I've done.that one wiU always be a highlight. 60.the second paragraph shows that          .
