U5 TO U8

I study political violence暴力 for a living, yet I, too, am shaken and unsure how to react. As I sit here today in my office, only a few miles from the still-burning Pentagon, images of the slaughter屠杀 in my native New York dominate统治 my thoughts. It makes it hard to concentrate on work, and it makes the everyday things seem so trivial轻微的. Only now, twenty-four hours after the tragedy 悲剧began to unfold,展开 have I begun to realize how this has affected me on so many levels.

As an American, I feel threatened 危机的and confused, where only yesterday I felt proud and invincible (不可战胜的). As a citizen of the global community, I have been shocked into the reality of the reach of global terrorism. As a human being, I am appalled at the cruelty and inhumanity of these acts of terrorism. As someone who hopes to understand unspeakable acts, I am at a loss to understand this one, perhaps because it hits so close to home.

I know only these things: Someone, for some reason, has decided to strike 打击at the United States. Despite the many people killed, the intended target of this attack was American power. The goal was to strike a paralyzing fear into the hearts and minds of all citizens of the U.S., and perhaps its allies协约国 as well. Thus, we -- all of us -- are the real targets of this attack. This explains why many of us, even those of us who were not near the attacks, or who knew no one affected by them, felt this tragedy so deeply.

Yet we must not succumb屈从 to fear, for if we do the terrorists have won. Surely our lives will be different now. We may be more aware, more inconvenienced不方便, more insecure不安全. But we must learn to deal with this tragedy and to move on, to live our lives as fully and as entirely as before. I came to my office today, even though classes here have been cancelled, to live my life as normally as possible, for to do so in the face of yesterday's terrorist attacks is itself an act of defiance. 21.

Gray clouds move as low as smoke over the treetops树梢 at Lolo Pass. The ground is white. The day is June 10. It has been snowing for the past four days in the Bitterroot Mountains. Wayne Fairchild is getting worried about our trek 徒步旅行over the Lolo Trail -- 95 miles from Lolo Montana to Weippe in Idaho, across some of the roughest country in the West. Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo. Today Fairchild is nervously checking the weather reports. He has agreed to take me across the toughest, middle section of the trail 小路-- \with this weather?\

When Lewis climbed atop Lemhi Pass, 140 miles south of Missoula, on Aug. 12, 1805, he was astonished 惊讶的by what was in front of him: \关阔的 ranges of high mountains still to the West of us with their tops partially covered with snow.\Nobody in what was then the US knew the Rocky Mountains existed, with peaks twice as high as anything in the Appalachians back East. Lewis and Clark weren't merely off the map; they were traveling outside the American imagination. Today their pathway小路 through those mountains holds more attraction than any other ground over which they traveled, for its raw wilderness is a testimony 证明to the character of two cultures: the explorers who braved its hardships and the Native Americans who prize and conserve 保存the path as a sacred (神圣的) gift. It remains today in virtually实际上 the same condition as when Lewis and Clark walked it. The Lolo is passable only from July to mid-September. Our luck is holding with the weather, although the snow keeps getting deeper. As we climb to Indian Post Office, the highest point on the trail at 7,033 ft., the drifts are 15 ft. and up. We have covered 13 miles in soft snow, and we barely have enough energy to make dinner. After a meal of chicken and couscous, I sit on a rock on top of the ridge.山脊 There is no light visible in any direction, not even another campfire. For four days we do not see another human being. We are isolated in a way that mixes fear with joy. In our imagination we have finally caught up with Lewis and Clark. 26. We learn from the passage that before 1805 _______.

C) now attracts large numbers of tourists D) is the meeting point of two cultures

29. Judging from the context, Lewis and Clark were most probably ________. A) two native Indians
