WASHINGTON - President Obama and his wife, Michelle, handed out Halloween treats to area
children and military families at the White House Sunday evening.
Local students between 6 and 14 years old, along with children from military families, were invited to
celebrate Halloween on the North Lawn.
The president and first lady, along with Mrs.Obama's mother, Marian Robinson, spent about 30
minutes passing out goodie bags.Obama wished each child a happy Halloween as he distributed the
treats, pausing occasionally for hugs or to comment on costumes.
Later, the military families continued the celebration inside the White House.
The first couple joked to assembled reporters about children walking the long driveway in order to
work off (消化掉) the snacks."This is the Let's Move method of trick-or-treating (不给糖就捣蛋),"
Obama said, referring to Mrs.Obama's campaign to combat childhood obesity (肥胖).
The goodie bags contained a box of White House M&Ms, a cookie made by pastry chef (点心师)
Bill Yosses, and dried fruit.
As they made their way across the lawn, the children meet a vast range of costumed characters
ranging from a spooky Frankenstein (科学怪人,小说《弗兰肯斯坦》的主角) to the Scarecrow
from "The Wizard of Oz ." Music from a jazz band dressed in pirate gear rang out across the White
House grounds.
Multicolored pumpkins and gourds lined the driveway - individually, in gravity-defying stacks and as
part of a large mound over 5 feet tall.Pumpkin-headed scarecrows (稻草人) made of cornstalks loomed
over the path with menacingly raised arms.Under the White House portico, a mobile resembling bats
flying through clouds fluttered around a lantern.
Some of the local trick-or-treaters were students at Bancroft Elementary, which helps tend the first
lady's White House garden, and Tubman Elementary, which has a relationship with the White House
chefs.
After trick-or-treating ended, the Obamas stood near the front door, welcoming the military families
inside, helping children climb the short flight of steps and thanking parents for their service.
