Many of us love July because its the month when natures berries and stone fruits are in abundance. These colourful and sweet jewels from British Columbias fields are little powerhouses of nutritional protection.

Of the common berries， strawberries are highest in vitamin C， although， because of their seeds， raspberries contain a little more protein （蛋白質）， iron and zinc （not that fruits have much protein）. Blueberries are particularly high in antioxidants （抗氧化物質）. The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries （櫻桃）， they are so delicious. Who cares？ However， they are rich in vitamin C.

When combined with berries of slices of other fruits， frozen bananas make an excellent base for thick， cooling fruit shakes and low fat “ice cream”. For this purpose， select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like， a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks， depending on their ripeness and the temperature of the freezer.

If you have a juicer， you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert， to be eaten right away. This makes a fun activity for a childrens party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.

Sports can help you keep fit and get in touch with nature. However， whether you are on the mountains， in the waves， or on the grassland， you should be aware that your choice of sport might have great influence on the environment.

Some sports are resource-hungry. Golf， as you may know， eats up not only large areas of countryside， but also tons of water. Besides， all sorts of chemicals and huge amounts of energy are used to keep its courses （高爾夫球場） in good condition. This causes major environmental effects. For example， in the dry regions of Portugal and Spain， golf is often held responsible for serious water shortages in some local areas.

In fact， there are many environment-friendly sports. Power walking is one of them that you could take up today. You dont need any special equipment except a pair of good shoes， and you dont have to worry about resources and your purse. Simple and free， power walking can also keep you fit. If you can walk regularly， it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious， sleep well and control your weight better.

Whatever sport you take up， you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors， in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all， its free.
