Whoever has made a voyage up the Hudson River must remember the Catskill Mountains. They are a branch of the great Appalachian family, and can be seen to the west rising up to a noble height and towering over the surrounding country. When the weather is fair and settled, they are clothed in blue and purple, and print their beautiful shapes on the clear evening sky, but sometimes when it is cloudless, gray steam gathers around the top of the mountains which, in the last rays of the setting sun, will shine and light up like a crown of glory (华丽的皇冠).

At the foot of these mountains, a traveler may see light smoke going up from a village.

In that village, and in one of the houses (which, to tell the exact truth, was sadly time-worn and weather-beaten), there lived many years ago, a simple, good-natured fellow by the name of Rip Van Winkle.

Rip's great weakness was a natural dislike of all kinds of money-making labor. It could not be from lack of diligence (勤劳), for he could sit all day on a wet rock and fish without saying a word, even though he was not encouraged by a single bite. He would carry a gun on his shoulder for hours, walking through woods and fields to shoot a few birds or squirrels. He would never refuse to help a neighbor, even in the roughest work. The women of the village, too, used to employ him to do such little jobs as their less helpful husbands would not do for them. In a word, Rip was ready to attend to everybody's business but his own.

If left to himself, he would have whistled ( 吹口哨) life away in perfect satisfaction; but his wife was always mad at him for his idleness (懒散). Morning, noon, and night, her tongue was endlessly going, so that he was forced to escape to the outside of the house -- the only side which, in truth, belongs to a henpecked husband.

美国农业部的数据库里有常见食物的各种维生素含量，有人统计了各种食物在“生”和“熟”状态下的数据，剔除含水量变化的影响，得出了各种维生素通过加热之后的损失比例，虽然这些数据不一定非常准确，但是足够我们得到一个有意义的印象：维生素A和E受温度影响不大，食物加工为熟食之后损失为10%左右，维生素C的损失是16%，而维生素B最不稳定，损失为26%，其他的维生素也基本上在这个范围之内。总体而言，把食物加热做成熟食之后，维生素的损失大致在10%～25%之间。
这段文字主要强调的是( )。

A．生食与熟食的维生素含量差异并不大，熟食只比生食少10%～25%
B．食物中不同维生素受温度影响不同，各种维生素在加热后损失率在10%～25%之间
C．加热对食物中维生素破坏作用并不大，加热后维生素的损失率在10%～25%之间
D．虽然不同维生素受温度影响程度略有差异，但总体上，加热对维生素的破坏并不大
