题目解析：
【题目翻译】：根据第1段，来自恒星的能量和被视为光的能量是结果
A：与氦原子结合的质子
B：重元素的原子粉碎在一起
C：各种颗粒彼此熔合
D：氢原子分裂
【判定题型】：题目问的是文章中的具体细节信息，故根据题目问法可以判断本题为事实信息题。
【关键词定位】：根据题干中的关键词“energy”和“light”我们可以定位到第一段第7句话“This energy, expelled into space, is what we see as starlight.”那么这句话中的“this energy”具体指的是什么呢？我们再往前看第6句“Each time fusion takes place, energy is released as a by-product.”从这句话中我们知道，这种能量是核聚变的副产物。因此，本题的答案就应该是核聚变。虽然答案中并没有直接出现“nuclear fusion”核聚变，但是C选项“各种微粒互相融合”其实就是对核聚变的一种解释。文中“The fusion process begins when two hydrogen nuclei smash together ……can fuse together to form heavier elements, such as carbon.”这段话都是在描述核聚变的过程，即2个氢原子碰撞→氘核，氘核+其他质子→氦，氦融合→重元素,e.g.碳。总之，核聚变的过程就是微粒不断互相碰撞融合的过程。
【逻辑分析】：关键词所在句子与题目所问的问题来自恒星的能量和被视为光的能量是结果是各种颗粒彼此熔合
【选项分析】：
C选项：核聚变的过程就是微粒不断互相碰撞融合的过程。故C选项正确。
A选项：质子与氦原子结合。错误，因为文中只说质子和中子结合成氘核，而氘核又与其他质子结合形成氦，并没有说质子与氦原子结合，故排除。
B选项：重元素的原子互相碰撞。错误，因为文中只说2个氢原子碰撞能形成氘核，并没有提到重元素原子的碰撞，故排除。
D选项：氢原子分裂。错误，因为整段话没有提到氢原子分裂，故排除。
Until the early- to mid-twentieth century, scientists believed that stars generate energy by shrinking. As stars contracted, it was thought, they would get hotter and hotter, giving off light in the process. This could not be the primary way that stars shine, however. If it were, they would scarcely last a million years, rather than the billions of years in age that we know they are. We now know that stars are fueled by nuclear fusion. Each time fusion takes place, energy is released as a by-product. This energy, expelled into space, is what we see as starlight. The fusion process begins when two hydrogen nuclei smash together to form a particle called the deuteron (a combination of a positive proton and a neutral neutron). Deuterons readily combine with additional protons to form helium. Helium, in turn, can fuse together to form heavier elements, such as carbon. In a typical star, merger after merger takes place until significant quantities of heavy elements are built up.
