（一）

They are the sort of friends who are so close they trust each other with their lives. If one falls, the other is there to catch him.

They are Wellman, whose legs were permanently injured nine years ago in a rock-climbing accident, and Corbett, an experienced rock climber. Together, they climbed up Half Dome, the famous 2,000-foot rock in the Yosemite National Park, through one of the most difficult routes(路线).

During the climb, Corbett took the lead, hit in the metal spikes(尖状物)that guided the ropes and climbed up. Then, after Wellman pulled himself up the rope, Corbett went down to remove the spikes and climbed up again. This process was repeated time and again, inch by inch, for 13 days.

Wellman’s job was not easy either. He got himself up the rope through upper body strength alone. In all, Wellman figured that he had done 5,000 pull-ups up the rope on the climb.

However, when the two men first met, they never talked about climbing. “He knew that was how I got injured.” Wellman said. Until one day Wellman decided that he wanted to climb again and they started training.

Their climb of Half Dome was not all smooth. At one point, pieces of rock gave way, and Corbett dropped down quickly. Wellman locked their rope in place, stopping the fall at 20 feet. His quick action probably saved his friend’s life.

“Your partner can save your life — you can save your partner’s life,” Wellman said as the pair received congratulations from friends. “There are real close ties.”

【文章大意】在现实生活中，不管作什么事情，人人互助就能克服任何困难，甚至挽救生命。Wellman和Corbett的经历恰好印证了这个道理。

1.【解析】选B。细节理解题。根据文章可知，C项和D项是Wellman所为，因此排除。根据第六段可知，Corbett在攀爬之中掉了下去，是Wellman及时固定住缆绳阻止住他下落，他得再次攀爬上去，对他来说这是个最大的挑战，因此选择B项。

2. 【解析】选C。推理判断题。根据句子when the two men first met, they never talked about climbing. “He knew that was how I got injured.” Wellman said和…Wellman, whose legs were permanently injured nine years ago in a rock-climbing accident可知，他们没有谈论攀岩是因为Corbett不想伤害Wellman这个残疾人的自尊。A、B、D项没有提及。

3. 【解析】选C。推理判断题。根据第五段可知，Wellman过了一段时间才决定再次攀岩，于是他们二人共同训练，因此C项正确。A项课文中没有提及;B项错在in a traffic accident，应为in a rock-climbing accident;D项错误，应为Wellman挽救了Corbett的生命。

4. 【解析】选B。主旨大意题。通读全文可知，Wellman和Corbett通过在攀岩活动中互相帮助，战胜困难，甚至挽救生命的事迹，歌颂了友谊之珍贵，文末的There are real close ties也能说明C项正确。A项意为“一人不敌二人计”。
