C

Now, we know that if we do not get enough vitamins, we are at the risk of devel?oping a number of diseases. As a result, vita?min supplements(補(bǔ)品)，though expensive, are popular with people who worry that they are not get?ting enough vitamins from the foods they eat. But contrary to what many people think,medical experts have found lit?tle evidence that most supplements do anything to improve health or protect against diseases.

In fact, medical experts warn that taking too many of some vitamins can be harmful. For example*too much vita?min E can cause bleeding. People should discuss what vita?mins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.

Experts, however, do say that sometimes vitamins can help prevent diseases. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time in?side may need some extra vitamin D as the skin makes this vitamin from sunlight.

Different vitamins are found in different foods. Vita?min A is found in fish liver oil. It's also in the yellow part of eggs. Sweet potatoes, carrots and other darkly coloured fruit and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruit. Vitamin K can be found in pork products.

In fact, for most people, a balanced diet can ensure enough vitamins our bodies need. So,it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins.

[文章大意]吃維生素補(bǔ)品其實(shí)并不像人們想象的那樣能帶來很多好處，有時(shí)維生素?cái)z取過量會對人體有害，人們通過合理的飲食就能夠獲得人體所需的維生素。

24.  C推理判斷題。根據(jù)文章的第一句"現(xiàn)在我們知道.如果體內(nèi)缺乏足夠的維生素，我們就有生病的危險(xiǎn)"可以推斷， 前面提到的內(nèi)容應(yīng)該是維生素給人體帶來的好處。
