Scientists have discovered 14 kinds of vitamins. If we do not get enough of the vitamins we need, we are at risk of developing a number of diseases. Scientists also find that it is better to eat vitamin-rich foods to prevent disease instead of eating them to cure a disease after it has developed. Which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.
Vitamin A helps prevent skin and other tissues from becoming dry. People who do not get enough vitamin A cannot see well in darkness. Vitamin A is found in fish liver oil and the yellow part of eggs. Vitamin C is needed for strong bones and teeth. The body stores little vitamin C, so we must get it in foods such as fruits and tomatoes. Vitamin D prevents the children from getting rickets (佝偻病). In some countries, milk producers add vitamin D to milk so children will get enough. Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding (流血).
Experts agree that everyone needs vitamins so that their bodies can operate normally. They also note that taking too much of some vitamins can be harmful and people should discuss what vitamins they need with their doctors. [br] Which of the following will be helpful to people who can’t see well in darkness?
选项
A、Tomatoes.
B、Fish liver oil.
C、Fruits.
D、Milk.
答案
B
解析
细节推断题。由文中第二段第二句可知,缺乏维生素A会引起视力问题;紧接着第三句又指出缺乏维生素A可以通过多吃鱼肝油和蛋黄补充,因此B)“鱼肝油”是正确选项。
