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 over the Lolo Trail95 miles from Lolo Montana to Weippe in Idaho, across 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.When Lewis climbed on top of Lemhi Pass, 140 miles south of Missoula, on Aug.12, 1805, he was astonished by what was in front of him; “high mountain chains 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.Today their pathway through those mountains holds more attraction than any other ground over which they traveled, for its raw wilderness is an evidence to the character of two cultures: the explorers who braved its hardships and the Native Americans who prize and conserve the path as a sacred (神圣的) gift. It remains today the same condition as when Lewis and Clark walked it.The Lolo is passable only from July to midSeptember. 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, we have covered 13 miles in soft snow, and we hardly have enough energy to make dinner. After a meal of chicken, 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 occupied with the things that mix fear with joy. In our imagination we have finally caught up with Lewis and Clark.1We learn from the text that before 1805 _.Athe Rocky Mountains were wholly covered with snowBthere were no people living in the western part of AmericaCno Americans knew of the existence of the Rocky MountainsDthe Appalachians were the western frontier of the United States答案：C细节理解题。根据第二段第一句中的“When Lewis climbed on top of Lemhi Pass,140 miles south of Missoula, on Aug.12,1805”和最后一句“Nobody in what was then the US knew the Rocky Mountains existed, with peaks twice as high as anything in the Appalachians back East.”可知，在1805年，没有人知道洛基山脉的存在。故C项正确。2We learn from the text that the Lolo Pass _.Ahas changed a lot since 1805Bis the meeting point of three culturesCremains much the same as it was 200 years agoDnow attracts a large number of tourists to visit答案：C推理判断题。根据第三段最后一句“It remains today the same condition as when Lewis and Clark walked it.”可知，the Lolo Pass和1805年Lewis和Clark走过的时候几乎一样。故C项正确。3Judging from the text，Lewis and Clark were most probably _.Atwo native IndiansBexplorers of the early 19th centuryCmerchants who did business with the IndiansDtravelers whose curiosity took them over the Lolo Pass答案：B推理判断题。根据第一段倒数第三句“Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo.”可知，200年前当Lewis和Clark经过the Lolo Pass的时候，他们几乎被暴风雪打败。Lewis和Clark很可能是当时的探险者。故B项正确。4We can infer from the text that when crossing the Lolo Pass the author _.Awas attempting the impossibleBwas trying to set a world recordCwas following the trail of Lewis and ClarkDwas fighting with weather and taking unnecessary risks答案：C推理判断题。根据文章最后一句“In our imagination we have finally caught up with Lewis and Clark.”可知，作者与Lewis和Clark走的是同样的路线。故C项正确。BTornadoes (龙卷风) are natures most violent storms, which can cause deaths and destroy a neighborhood in seconds. A tornado appears as a rotating, funnelshaped (漏斗状的) cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 miles per hour. Damage paths can be over one mile wide and 50 miles long. Every state is at some risk from this disaster.Some tornadoes can be seen clearly, while rain or nearby lowhanging clouds obscure others. At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.Before a tornado hits, the air may become very still. A cloud of debris (散片) can mark the location of a tornado even if a funnel can not be seen. Tornadoes generally occur near the edge of a thunderstorm, when the strong wind may die down. It is not uncommon to see clear, sunlit skies behind a tornado.The following are facts about tornadoes：The average forward speed of a tornado is 30 MPH, but may also vary from still to 70 MPH. Debris are picked up or a cloud forms in the funnel.The average tornado moves from southwest to northeast, but tornadoes have been known to move in any direction. Tornadoes are most often reported east of the Rocky Mountains during spring and summer months.Tornadoes can happen together with tropical storms and hurricanes as they move onto land. Waterspouts are tornadoes that form over water.Peak tornado season in the southern states of America is March through May; in the northern states, it is late spring through early summer. Tornadoes are most likely to occur between 3 pm and 9 pm, but can occur at any time.5From the passage, we can learn that tornadoes come from _.Ahurricanes Bgreat heatCthunderstorms Dsandstorms答案：C细节理解题。根据第一段第二句中的“A tornado appears as a rotating, funnelshaped (漏斗状的) cloud that extends from a thunderstorm to the ground”以及第三段第三句中的“Tornadoes generally occur near the edge of a thunderstorm”可知，龙卷风起源于雷雨。6What does the underlined word “obscure” probably mean?AHide. BReduce.CProduce. DRaise.答案：A词义猜测题。根据第二段的首句“Some tornadoes can be seen clearly . ”可知，有些龙卷风可以很清楚地看到，而有些龙卷风被雨或浮云遮挡而看不清楚。故obscure意为“掩盖，隐藏”。7When a tornado happens, _.Ait can only be seen in the late of the dayBit only moves from southwest to northeastCit may form on the surface of sea waterDit often reaches the speed of 70 MPH答案：C细节理解题。根据倒数第二段尾句“Waterspouts are tornadoes that form over water.”可知，有些龙卷风来源于海面。8The passage makes us believe that _.Awarnings about tornadoes are well developed in many countriesBof all the natural disasters, tornadoes often cause the biggest damageCtornadoes are mostly seen in the southern states of AmericaDtornadoes may strike so quickly there is often little or no warning答案：D推理判断题。根据第二段尾句“At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.”可知，很多时候龙卷风来得太快，以至于不可能提前发出警告，因此选项A错误而选项D正确；根据第一段首句可知选项B错误；根据末段可知选项C错误。语法填空When you smile, not only do you feel happy, _1_ you also bring a ray of light into the lives of others. Someone once _2_ (say), “A smile is a curve that sets everything straight. A smile is a
