    The other day, I bought an expensive anti-aging cream that promised to make my face look several years younger that other women by fighting free radicals. It made me curious about what free radicals ares.Is the anti-aging cream the only way I need to protect myself?

“As a scientific term, free radicals are essentially unstable atoms, “says Arizona-based doctor, Natasha Bhuyan, M. D. “In medicine, they cause cells to break down over time and are linked to aging.”

A super simple chemistry review for you: Atoms from different elements are the building blocks that make up water, nitrogen and more. Electrons (电子) are the negatively charged atoms, and they like to be in pairs. When an electron loses its partner, it creates a free radical, which is usually unstable and highly reactive. Free radicals typically go through the body to seek out a replacement for their missing electron, and that can result in damage to cells,proteins and DNA.

So how do free radicals form and why do they happen? Bhuyan says, “Scientifically, free radicals are unpaired electrons that are seeking a mate to bond with. The theory behind free radicals is that they can lead to the imbalance between free radicals and antioxidants (抗氧化剂).” Another mini-science lesson for you: Antioxidants are natural or man made matters that can help delay or prevent some types of cell damage. They’re often found in fruits and vegetables.

A lot of the aspects of modern life — our diet, lifestyle and environmental factors like pollution, can cause oxidative stress. Over time, oxidative stress weakens cell and tissues and can leave you more easily to certain health issues including cancer. And, as beauty marketers are keenly aware,oxidative stress can also speed up the aging process. Now that your know free radicals can weak on your health, you’re probably wondering if there are any ways to prevent them from forming or at least to minimize their negative effects.

1.What does the author intend to do in paragraph 1?

A.Explain the process of aging. B.State the formation of free radicals.

C.Introduce the topic of free radicals. D.Describe the harm of anti aging cream.

2.Which of the following do free radicals refer to?

A.Unpaired electrons. B.Steady atoms.

C.Replacements of atoms. D.Functions of electrons.

3.What can we learn about antioxidants from the text?

A.They have never been found in nature.

B.They do harm to cells, proteins and DNA.

C.They can slow down the damage of some cells.

D.They always keep balance with free radical.

4.What will the author probably tell us next?

A.What exactly oxidative stress is. B.How beauty marketers promote sales.

C.Where a variety of diseases come from. D.Whether free radicals can be prevented.
