Is there something that you’ve always wanted to try but just never had the time? Well, make plans to try it now since you are on summer vacation. Not all vacations call for taking a tour bus to take photos of famous landmarks. Some vacations allow you plenty of opportunities to learn.

The most difficult aspect of a learning vacation may be choosing one because the possibilities are endless. If you enjoy cooking, various companies can take you to Italy, France, Spain, Mexico or even Peru. Once there, you can learn to prepare the local cuisine(烹饪). Trips are often planned to fit in with local food festivals or special events.

The term “learning vacation” often brings languages to mind. The best way to learn a language is in an environment where it’s spoken. Study Spanish, French or Estonian or Thai. You’ll be able to learn about the country and absorb the culture at the same time.

If you are fond of sports, you can polish your skills or learn new ones. Golf and tennis schools welcome players of all levels. If you want a bigger thrill, you can learn to surf, go climbing or race cars. It’s even possible to learn the art and techniques of bull fighting while on vacation!

You can also discover our inner artist. Many places offer painting classes in different mediums. The scenic locations of the schools offer plenty of subjects that provide inspiration for practice.

If you prefer capturing the world on film, take a photography vacation. Travel with a small group to photograph beautiful animals or scenery. You can also practice your technique on people or at historical sights.

Once you decide on a vacation, choose a company carefully. Request names of recent customers you can contact, and then ask them for an evaluation. The more you know before you go, the better prepared you’ll be. Then go out and learn something!

Nature is full of colors, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots.

Plants and animals often use colors to attract attention. The substances(物质) responsible for these colors belong to a class of chemicals called antioxidants(抗氧化剂). Plants make antioxidants to protect themselves from the sun’s ultraviolet(UV) light.

Ultraviolet light causes chemicals called free radicals(自由基) to form within plant cells. They can destroy parts of the plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals.

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.

a. Wrinkled skin can be seen. b. UV light causes free radicals to form.

65. Which of the following can’t cause free radicals to form?

A. Polluted air. B. The body itself C. Colorful foods. D. UV light from the sun.

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.
