阳光课堂课时优化作业系列答案Public schools in Washington, D.C. provide students with musical instruments for free. When something goes wrong with an instrument, Charles West and Larry Jernigan do the repairs. Both men approach their work with a passion(激情). For them, it’s important that students have a joyful experience with music.
The two have worked together for almost 20 years. This year alone, they’ve fixed about 450 instruments. Both men are musicians and music lovers, so learning to do repairs came naturally.
“I have been a musician all my life.” says West. “I played in an orchestra here in the city. I majored in music in college. I played in an army band.”
Jernigan’s musical interests are varied. “I was formerly trained in the piano and guitar. The alto sax, and the flute, I picked up while working here.”
In addition to fixing instruments, the two also go to schools to instruct teachers and students on how to make minor repairs on their own.
West believes if children start early and stay concerned with music, it enriches other areas of their lives. “I see that in other kids. I see it in myself. I have seen it hundreds of times and it works,” he says. “They learn teamwork. They learn patience and respect.”
But West has concerns about the future of music in the electronic age.
“This instant age has taken away from the sit-down, the patience. And to learn to play an instrument, it takes patience, it takes diligence, it takes time.”
Being able to enjoy music on the job is one of the benefits of the job. Both men agree their best rewards are the students’ performances.

He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage workers that they called him "Our baby". In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave, carved with the words: “To the memory of an unknown child.” He has rested there ever since.
But history has a way of uncovering its secrets. On November 5 , this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. "This is our baby," says Magda Schleifer,68,a banker. She grew up hearing stories about a great-aunt named Maria Panula, 42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children----including a 13-month-old boy named Eino--from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea." says Schleifer.
Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now the family see no need for a new grave. "he belongs to the people of Halifax," says Schleifer. “ They've taken care of him for 90 years.”

Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iphone application Mealsnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately.
Mealsnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iphone applications. The applications gives users a quick reply. To do that, it matches the taken picture to a databank containing the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed.
We started with something simple — an apple. A couple of minutes later the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of mixed salad bowl. Mealsnap replied that the bowl contained “yellow rice with corn, boiled eggs and beans” and that the food was between 532 and 798 calories.
Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That’s why it is so popular among those who are trying hard to lose weight.
In addition, Mealsnap can serve as a food diary. No need to write down what they’ve eaten, the photos will be stored. Then users can keep a visual log (记录). Mr. Smith said: “It’s like a food journal, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological change that can help people on their health journey. Knowing the calorie range makes me think more about what I’m eating.

| A．help people have a healthy life |
| B．make iphone more popular |
| C．help people find ways to lose weight |
