小题1:_______________ Studies show that even in infancy(幼儿期)，music has an effect on the human brain. They have also shown that classical music can lower the blood pressure and calm an upset infant. Singing simple songs to your children is the beginning of enjoying music. 小题2:_______________ Fun little rhyming(押韵的) songs are very easy for children to learn, even with a very limited vocabulary. They will pick up the words and tune quickly and find that singing is a great way to lift their own spirits. 小题3:_______________ Some kids enjoy watching music videos. There are also music videos that are inspiring, uplifting and just plain entertaining, such as Disney’s Fantasia 2000. Kids are attracted by the images they see moving to even the smallest differences of music. Many teachers use these videos to teach about music terms. 小题4: _____________ If you make friends with an instrument you will have a friend for life. Learning to play an instrument can lead to a life-long love of music. When possible, create opportunities for your child to see a soloist(独奏者) playing her or his particular instrument for inspiration. 小题5:_____________ A long trip can be made shorter and more fun by singing. Teaching your kids some of the songs you grew up with can also be fun. There are a lot of sing-a-long CDs and downloads available(可用的)，so create a travel mix, and not only will your children enjoy the music more, they will also enjoy the fond memories to the family singing together on the trip to Grandma’s house. |
