Question

Grey clouds move as low as smoke over the treetops 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 over the Lolo Trail-95 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 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,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.

推理判断题答题技巧

解答推理判断题要以文字信息为依据，既不能作出在原文中找不到依据的推理，也不能根据表面文字信息进行多余推理。也就是说，要做到判断有据，推论有理，忠实原文。切忌用自己的观点代替作者的本意，切忌片面思考，得出片面结论。

细节推断题是推理判断题中比较简单的一类试题，它要求考生根据语篇中具体的内容和信息点，推断出文章中具体的细节，如时间、地点、人物关系、人物身份、事件等。解答此类试题时，一般可根据短文所提供的信息或者借助生活常识进行推理判断。考生只要正确把握文章的内在关系，理解文章的真正含义，就可作出准确的推断。

对于细节推断题来说，根据文章中的关键信息点进行推断是解答此类试题的关键。考生不但要理解文章的字面含义，还要运用逻辑判断能力，推断出文章更深层的含义。同时还要根据文章内容进行推断，不能凭空猜测。考生要注意站在文章作者或文中人物的立场上，设身处地地考虑实际情景，并据此展开合理的想象和推理。主观臆断是许多考生做这类题时普遍存在的一个问题。
