未来，木星会取代太阳吗？

    ①在太阳系中，木星是行星中的“巨无霸”。它的体积和质量分别达到了地球的1320倍和318倍。不过，除此以外，木星的独特之处还在于它能发光，有自己的能源。

    ②也许你并不觉得这是什么稀罕事，那么我们先来看一下行星的定义：行星通常是指自身不发光、环绕着恒星的天体。其公转方向常与所绕恒星的自转方向相同。一般来说行星需具有一定质量，行星的质量要足够的大且近似于圆球状，自身不能像恒星那样发生核聚变反应。在人们的通常认识中，行星的确不能发光，只能依靠反射太阳的光线。但科学家研究发现，木星正在把巨大的能量不断地向周围的宇宙空间释放，它释放的能量，相当于两倍从太阳那里所获得的能量，说明木星有一半的能量来自它的内部。

    ③分别于1972年和1973年发射的“先驱者”10号与11号飞船探测的结果显示，液态氢构成了整个木星。它同太阳一样，没有坚硬的外壳，主要是通过对流形式来实现能量的释放。前苏联科学家齐巴罗夫和苏齐科夫认为，木星的核心温度已达到30000℃之高，热核反应还在其内部继续进行。

    ④那么，我们不禁要问一个严肃的问题：未来，木星会渐渐取代太阳吗？

    ⑤正如之前所说，木星是由液态氢构成的，本身并无坚硬的外壳。木星的这种构成与太阳构成方式十分相似，主要是通过对流形式来实现能量的释放。木星不仅把自己的引力能转换成热能，还在不断吸收太阳释放的能量，这就使它的能量越来越大，且热度越来越高，并使它达到了现在的高度。从木星目前的发展趋势看，它很可能成为太阳系中与太阳相差无几的第二颗恒星。

    ⑥30亿年以后，太阳到了晚年，木星很可能取代太阳的地位。虽然时间还很远，但人类不得不面对一个事实是，太阳已经是一颗垂暮的恒星了，它的光辉总有一天会熄灭，而木星的自带光源，点燃了生命顽强延续下去的希望。

阅读下列短文，根据短文内容，从短文后各题所给的A、B、C、 D四个选项中，选择最佳选项。

Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now, scientists are trying to understand shyness. They have some interesting ideas about why people are shy.

Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies behave shyly. These babies are a little quieter and more watchful than other babies. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic.

Family size might cause people to be shy as well. Scientists at Harvard University studied shy children. They found that 66 percent of them had older brothers and sisters. As a result, they became shy. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families.

You may also be shy because of where you were born. When scientists studied shyness in different countries, they found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the difference? One scientist says the Japanese and Israelis have different opinions of failure. In Japan, when people do not succeed, they feel bad about themselves. They blame（责备）themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends, or bad luck. In Israel, freedom of opinion and risk taking are strongly supported. This may be why Israelis worry less about failure and are less shy.

For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversation. And don't forget---if you are shy, you are not the only one.
