D1:
1. D。从“was born without legs now”，“he is No 1 in the US”和“He played six matches and won five of them”可判断D正确。
2. B。从“The most important thing is that he’s happy”和“That’s a great example of being happy even if life doesn’t give you everything”可知，Nadal对他印象最深的就是享受打网球的乐趣。
3. A。从“I just try to stay positive”可判断A正确。
D3:
1. C. 根据But the problem is that the flu virus can change so quickly that the ends of its hemagglutinin change completely from year to year, which is why a vaccine from one year may fail the next year可知原来的流感疫苗由于hemagglutinin的频繁变化经常时效，所以每种流感疫苗只能针对一种流感病毒，而科学家研究的目的就是能够开发出针对多种流感疫苗有效的通用流感疫苗。
2. D. 根据Because these stems aren’t very different in different types of the flu, an antibody that attacks the stem should work on many different flu viruses可知D正确。科学家研究的这种通用疫苗以病毒的stem为目标，所以可以适用于多种流感病毒。
3. D. 根据最后一段Still, one concern is that flu viruses could change their stems against this new type of vaccine. “It’s a race with all of these viruses,” Wilson said. Only more research, including tests on humans, will answer these challenges可知流感病毒未来也可能在stem部分发生变异，从而使得通用流感疫苗失效，因此开发疫苗的过程实际上就是科学家与病毒之前的竞赛。
D4:
1. 选C。根据第二段，当看到鳄鱼靠近儿子，母亲快速走向水边并大声喊叫，提醒孩子。
2. 选A。根据第六段“His legs were extremely scarred by the animal’s attack, and on his arms were scratches from his mother’s fingernails”可知A正确。
3. 选D。根据第六段小男孩说的话，他告诉记者他的胳膊上也有伤疤。这是因为母亲为了救他，用力拉他胳膊时手指甲刮擦所留下了。这是母亲对他永不放弃的证明。
4. 选D。根据第七、八段，我们普通人有时候和那名小男孩一样，我们都会有伤疤，有的伤疤是痛苦的留痕，有的伤疤是爱的印证，唯一不同的，只不过我们的伤疤也许没有小男孩的伤疤来得那么戏剧性罢了。
