Our bodies have natural defences for fighting off free radicals. While we’re young, our defences are pretty strong. However, they get weaker as we get older. The body’s built in defences can only go so far without extra help.
The key to fighting free radicals with fruits and vegetables is to mix and match colors. It’s like sunscreen(防晒霜) for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else.
Research into how chemicals in blueberries affect the brain’s function in rats suggests that these chemicals may help our own brains work more efficiently.
Don’t just blame the sun. Ultraviolet light isn’t the only source of free radicals. If you breathe polluted air, such as smog, automobile exhaust(废气), or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food.

Vans, Keds, Dollies--they sound like the names of rock bands, but if you have teenagers, you’ll know they’re actually the latest in teenage footwear.
But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing years of foot, knee and back pain in the future.
Here, the experts identify the problems caused by teenagers’ shoe choices.
KEDS/VANS
SLIP – on shoes with elastic(弹性的) sides are particularly popular among teenage boys --- with Keds and Vans the most popular brands.
The main problem is that they are just too flat—so flat that the heel, which strikes the ground first, also becomes damaged and painful.
BALLET PUMPS
The worst shoes of all are such light and thin dolly shoes. The problem is partly their flat-pumps, which have no string or heel, have other specific problems.
“As the shoe has no fastening device, it relies on toes to keep the shoe on, causing an awkward gait(步法)， this lead to short- and long-term problem such as calluses(茧子), heel and knee pain.”
WEDGES AND STILETTOS
These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer’s body weight forward, making them very unstable.
Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain.
SCHOOL SHOES
So what do podiatrists(足科医生) have on their wish list, especially for everyday wear? Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark’s Marks & Spencer of Rhino.
If your teen insists on wearing “bad” shoes, get them some simple foot orthotics(矫形器) in the shoes. These support and correct movement of the foot and, properly fitted by a podiatrists, can often transform their walk and halt the damage.
66. Of all the shoes mentioned in the passage, which can cause the worst problem?
A. Marks & Spencer B.Wedges & Stilettos
C. Keds and Vans D. Ballet pumps
67.The underlined word “halt” in the last paragraph probably means __________.
A. increase B. worsen C. cure D. stop
68. From this passage we can infer _________.
A. fashionable shoes all have orthotics in them.
B. trendy shoes may ruin teenagers’ health
C. experts are strongly against wearing poplar shoes
D. podiatrists are expert at producing branded shoes
69.In which column of Mail Online can you find this passage?
A. Science B. Sports C. Health D. Shopping
70. Which pair of shoes may not be found on the podiatrists’ wish list?
A. B. C. D.
