如果运动员想有更出色的表现，他们应该在高海拔地区训练。在高海拔地区，身体中每单位体积的血液里含有的红血球数量比在海平面上多。红血球运输氧气，而氧气供应充足便能提高竞技水平，在高海拔地区训练的运动员每单位体积的血液能运载更多的氧气，这样便会有更出色的表现。 如果运动员的心跳速率在高地时和在低地时相同，下面哪个如果正确，对上面的论点打击性最大( )

A．科学家发现运动员的心脏需要一段时间调整，才能适应在高海拔地区的训练

B．科学家发现在高海拔地区人体内的血液总量降低了25%

C．在高原训练的中距离跑运动员有时会败给在海拔为零的平地上训练的运动员

D．在过去20年，运动员在所有高海拔地区进行的比赛中成绩都明显提高了，

     In World War Ⅱ, a large and strong German army marched (行军) to France for making a war against

the Frenchmen. The Frenchmen, a brave group of people, loved their own country deeply. They put their

hearts into fighting hard to drive their enemies out of France. But it looked as if the German army would

win the war because there were so many Germans in the battle.

     One night, the leader of the Frenchmen was forced to withdraw (撤退) his soldiers to the top of a tall

building after a dissatisfactory war. "We will have a rest here tonight, my men," he said, "Tomorrow we

will fight one more serious battle. We must win or we will all die." At that time, they were all so tired that

they soon fell asleep after they ate their supper quickly. There were only four guards on duty. But they

were also very exhausted and fell asleep one by one.

     The foxy Germans were not asleep. Quickly they gathered at the foot of the building. Slowly they went

up the building carefully making no noise. Closer and closer they came to the sleeping Frenchmen. They

almost reached the top. The war would be over a few minutes later. Suddenly, an earthquake shook and the

building was destroyed right away. Most soldiers of both sides fell down and were buried under the useless

pieces of the building. Terribly, the war ended with an unbelievable result.
