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 is the best title for the passage?
选项
A、Healthy Diet
B、Various Vitamins
C、How to Get Enough Vitamins?
D、Vitamins Are Important to Good Health
答案
D
解析
主旨大意题。本题考查文章标题。分析全文大意可知。文章首先讲人体如果缺维生素会有患病的风险;随后列举出几种维生素的功能及其食物来源;最后总结维生素是人体正常运转所必不可少的,但也告诫人们不要滥补。由此可见,文章主旨是强调维生素的重要性以及合理补充的必要性,D)符合文章大意。
