【解析】维生素对于我们来说是很必要的，各种维生素有不同的功能，这篇短文中给我们介绍了维生素A、B、C、D的功能，以及含有这些维生素的食物。

1.根据短文中Without vitamin A, you cannot see well in darkness．Vitamin A is found in animal liver and yellow part of eggs．Sweet potatoes, carrots and other dark colored fruit and vegetables have something that the body can change into vitamin A可知，维生素A对我们的眼睛有好处，它富含于动物的肝脏和蛋黄中，一些深颜色的水果和蔬菜也有一些可以转化成维生素A的东西。由此可知这句话是正确的。

2.根据短文中It is found in grains and other foods like beans, nuts, meat and fish可知，维生素B可以在谷类和其他的食物如大豆、坚果、肉和鱼中发现。由此可知这句话是错误的。

3.根据短文中Vitamin C is needed for strong bones and teeth, and for healthy blood vessels (血管)．It also helps wounds to heal (愈合) quickly可知，维生素C有利于强壮的骨骼和牙齿，对健康的血管有好处，也可以帮助伤口快速愈合。并没有说对皮肤有好处，故这句话是错误的。

4.根据短文中In some countries, milk producers add vitamin D to milk so that it will be good for children可知，在一些国家里，牛奶生产商往牛奶里加入维生素D，是为了对孩子有好处，并没有说帮助孩子产生血液细胞。故这句话是错误的。

5.根据短文中Different vitamins are found in different foods可知，不同的维生素存在于不同的食物中，不是所有的食物中都有维生素，故这句话是错误的。

点睛：这篇短文给我们介绍了各种维生素的功能，以及富含这种维生素的食物。短文的结构很清楚，是总分的结构，第一段引出话题，下面的四段分别介绍了维生素A、B、C、D，这样的结构有利于我们做题的时候，搜索信息。首先我们应先理解题目中的句子，在里面找到关键词，例如我们可以用维生素的种类作为关键词，然后在短文中搜寻相关的信息，进行判断。例如第2小题，我们可以用vitamin B 作为关键词，定位到原文第三段，然后找到相关的句子，可以知道它是错误的。
