Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.

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

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

Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits 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 fruits. Vitamin K can be found in pork products.

In fact, for most people, a balanced diet can ensure enough of the 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 our bodies need.

1.What is probably talked about before this passage?

A. How many vitamins a person’s body needs.

A. people mistakenly think that they are good for their health

B. they contain more vitamins than the foods people eat

C. food does not provide enough vitamins people need

D. people fear that a lack of vitamins will lead to disease

If you don’t prepare yourself now, retirement may be some of the most boring and dull years of your life. To have a happy, fulfilling retirement, you need to start preparing right away.

The most obvious thing for people to do when they retire is to take up a hobby. The most important step to take before retiring, though, is to make sure that you actually have started some hobbies. Once you’re retired, unless you ‘ve already started a hobby, you’ll find it very hard to get into something new. Some hobbies aren’t for everyone. Think about what you enjoy doing and start participating on a casual basis now.

Another thing many people participate in is volunteering. Not only does volunteering give you something to do, it also gives you a sense of accomplishment(成就) and can add meaning to your life .Volunteering is also rewarding in other ways, too. There are hundreds of different types of volunteer services and you’ll always be able to meet new and interesting people. Also, don’t think that volunteering is always only about helping someone for free. Many companies pay their volunteers after they’ve had enough experience and prove themselves to be valuable workers.

There are plenty of other potions, as well. Going back to school is a great way to keep yourself feeling young. Taking a vacation around the world with your loved ones is another great way to spend your retirement.

Ultimately, though, the key to a happy retirement is simply keeping yourself busy and doing whatever you love. If there’s nothing you love doing now, then you’ll find that once you have a vast amount of free time, your life will be pretty empty. Now is the time to find out what you want to do when you retire.

1.Why does the author suggest starting a hobby before retirement?

A. Because we are likely to have difficulty starting a hobby after retirement.

B. Because we are gong to have a vast amount of free time after retirement.

C. Because we will only have a limited choice of hobbies after retirement

D. Because not every one of us has already started some hobbies already.

2.What can we learn about volunteering from the text?

A. We can make devoted friends through volunteering.

B. It can help companies find hard-working workers.

C. One can even make some money by volunteering.

D. Almost everyone is willing to help in some way.

3.Which of the following can best explain “a happy retirement”?

A. Travelling around the world every year.

B. Going back to university for further study.

C. Having plenty of free time for one’s hobbies.

D. Living a busy life and doing what one enjoys doing
