【文章大意】本文是一篇记叙文。作者讲述了1944年圣诞前夕，奶奶一家在集中营里日子艰难，迫不得已12岁的叔叔秘密走出集中营去附近的村庄求助，一位善良的女士给予了他们一家一些物质上的帮助。这位好心人的善举给了过着暗无天日的日子的奶奶一家不仅是物质上的帮助还有对未来的希望，最终一家人坚持到光明的到来。

2.B 推理判断题。开始提到鞋子是Gyuri妹妹没有合脚的鞋穿是他逃出集中营求助的原因之一，Gyuri的妹妹有了合脚的鞋后，小了的鞋就被送给了集中营里的一个比她小的孩子，而Gyuri的妹妹穿着好心人送的鞋迎来了自由，一家人走向了新生活，鞋子贯穿这个故事，因此推断作者多次提到鞋的原因是为了有助于故事的发展和文章主题的升华。故选B。

4.A 【解析】主旨大意题。纵观全文特别是文章最后一段可知，在积雪覆盖的寒冷的冬天，人们封闭自己，死亡比活下去更容易的情况下，这位善良的人不仅给予了奶奶一家物质上的帮助，而且给了他们希望和抚慰。就像黑暗中的亮光鼓励他们走向新的生活。因此推断这篇文章歌颂了黑暗中人性光明的一面。故选A。

The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they
