I am not an enthusiastic air traveler. Bustling through airports, getting checked by security, and standing in lines leave me     1    . But road trips are different. While the transit time is longer, opportunities to get off the beaten path(常走的路) make it     2    . I see places and interact with people and cultures that I otherwise tend to miss, rediscovering how far you can go and how much you can experience without leaving the United States. So, when my son said he wanted to tour the Kansas State University campus after receiving an admission offer, we threw our luggage and a case of bottled water in the car and     3     the highway. One attraction of traveling at the speed of a car is the transitions. Arizona's Meteor Crater(陨石坑), Two Guns, and Painted Desert give way to New Mexican villages, then farm towns. Red rocks become open plains and grain elevators are the only features     4     above endless miles of flatness.

That flatness poses an unexpected challenge when there's nothing to step behind. Eating on the road can also be a challenge. For basic food, Anthony and I relied on Subway sandwich shops, which offer the same reliable fare(饭菜) at every location. While not exactly a     5     of local cuisine, they didn't leave us regretting lunch when we returned to clocking miles. Salads were curiously difficult to find in the college town of Manhattan, Kansas, although we had no     6     about the burgers and barbecue.

In contrast to airport excursions, which often feature conflicts and even confrontations, our trip was entirely     7    . When you meet folks in their natural environment after hours of changing scenery, it's easier to remember just how big the world is and to     8     that many of its inhabitants are perfectly happy living     9    , and there's no reason they shouldn't be.

As it turned out, the greatest source of stress was the frequent reminder that my son changes     10     like he's afraid of missing a sharp turn. Fortunately, that's a travel headache that can be fixed.

The virtual choir was the idea of award-winning     1     and conductor Eric Whitacre. Born in the USA on 2 January 1970, Whitacre began studying music at the University of Nevada in 1988. He fell in love     2     Mozart’s classical music when he sang for the university choir. Moved by this music, he said, “It was like seeing color for the first time.” He     3     from university in 1995, and then received a master’s degree in     4     composition from the Juilliard School in New York in 1997. Over the next 10 years, Whitacre’s original compositions began to become quite popular among choirs and singers. This led to the     5     of the virtual choir.

In 2009, Whitacre received a video of a girl who was singing one of his works.     6    , he asked his fans to     7     videos, which he then joined together into one performance. His first virtual choir, “Lux Aurumque”, had 185 singers from 12 different countries. It has received millions of     8     on the Internet. Since then, the virtual choir has become a worldwide phenomenon. Whitacre’s next     9     was the Virtual Youth Choir for UNICEF, which was first seen on     10     on 23 July 2014 in the UK. Altogether, 2,292 young people from 80 countries joined in to sing Whitacre’s song “What If”.
