A、Kabul B、Arlington C、Baghdad D、Kandahar B

This is the day when America remembers those who died in service to their country. And nowhere is the extent of their sacrifice more on display than in Arlington National Cemetery-- where seven generations of the fallen are buried. President Bush spoke in the cemetery’ s amphitheater-- a massive white structure surrounded by seemingly endless rows of small white headstones. Many of the nation’ s greatest military heroes are buried in Arlington. But so too are hundreds of thousands of men and women whose names arc known only to the families and communities that mourn them. They include several hundred soldiers killed since the September 11 attacks on the United States in places like Kabul and Kandahar, Baghdad and Ramadi. The sod is still fresh on those graves, many covered with personal messages, flowers and flags. The president said their sacrifice must not be in vain, and the cause of protecting freedom will never end. Earlier, the president laid a wreath at the Tomb of the Unknowns, which contains the unidentified remains of members of the U.S. military killed in major conflicts. He was accompanied by several families of the fallen.
