Spring is here and so is the cycling season. Here are some tips on how to do it safely and comfortably.

Watch your feet—Pushing with the wrong part of the foot can raise your risk of developing a painful injury of the heel and arch（脚心）, says Rob Werstine, a sports physiotherapist（理疗师）and board member of the Canadian Physiotherapy Association.  You should push with the ball of your foot, he says.

Layer up—While it’s still cool, wear layers of clothing, with clothing close to the body that breathes and outer layers that do not absorb water. Go for bright colors that increase your visibility（可见度）.

Be reasonable—If you are just starting out and aren’t in good shape, don’t sign up for a 50-kilometre ride. And while cycling is great exercise for people who want to get into shape, if your doctor advises you not to do tiring exercise, cycling shouldn't be your starting position, Werstine says. Walk to begin getting into shape and then graduate to cycling.

Fix the fit—If you develop lower back pain or numbness in your hands and fingers from cycling, it could be your bike isn’t adjusted properly for your height. A good cycle shop can help you find the right height for the seat and handlebars, but if you have continuing problems, consider consulting a bike fit physiotherapist, Werstine says.

Be mindful—You have to pay attention on the roads to vehicles, other cyclists and pedestrians（行人）.Consider taking a cycling safety course to practise your skills. Or do some reading about how to avoid dangerous cycling situations. bicyclesafe.com, for instance, lists 10 types of car-bike accidents and how to avoid them.

1.Which part of the foot should one use when cycling?

A．The heel.          B．The arch.          C．The ball.          D．The toes.

2. From Paragraph 4 we can conclude______.

A．not everyone can exercise by cycling        B．walking is better than cycling

C．cycling is popular with people              D．cycling is helpful to everyone

3.According to the last paragraph, if you want to avoid danger when cycling, you should ______.

a. consider taking a cycling safety course

b. search for information on bicyclesafe.com

c. consider consulting a bike fit physiotherapist

d. adjust the bike properly for your height

Summer is the perfect time to relax. As you plan for your trip, here are some tips on how to protect yourself. 1.

Fight against the mosquitoes in the hot spots.

There are many mosquito-borne illnesses in tropical regions, which are traditionally vacation hot spots. Therefore, mosquito repellent（驱蚊剂）that contains DEET should be an essential item in your travel bag.

2.

In lesser-developed countries there is less equipment for clean water and public health. If you can't avoid unhealthful water, make sure you bring along a tea or coffee—making pot that will boil water for you. You’d better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

Always protect your feet.

It's best to wear slippers in the shower, but if you must be barefoot, put a towel down on the floor.3.You should never walk barefoot in any area of a foreign country, including your hotel room.

Be sure to eat safe fruits.

4. They may have been washed in the same water, or wiped with the same rag used to clean work surfaces in kitchens. The best advice is to bring your own peeler（削皮器）so that you know that something clean has been applied to the fruit.

Enjoy the smell of roadside stands, not the food.

Unless the food is piping hot when served, it’s best to stay away from roadside stands, no matter how good the smell of the food might be. If you are concerned about whether a restaurant is clean, order the food to go. 5.

A. Don't trust the local water

B. Any fruit served fresh may be polluted

C. Look out for any water not served in a bottle

D. The boxes may be cleaner than the plate or fork on the table

E. You should know how to keep yourself away from dirty fruits

F. They are necessary to avoid coming back with a major illness from your trip

G. Parasites（寄生虫）can enter the skin of your feet and travel to different parts of the body

Living in the wild can be hard．Finding food and staying safe aren't easy．Each day, animals try to survive in their habitats．Not all animals get by on their own. Some animals form a close partnership with other kinds of animals．These pairings are called symbiotic(共生的)relationships．

Small birds called plovers（灰斑）are also in the cleaning business．They have big customers-crocodiles.Crocodiles have long noses filled with sharp teeth. Cleaning them is funny. When a crocodile opens its mouth, the plover hops right in．It lets the plover eat small, harmful animals attached to the crocodile's teeth．The plover gets an easy meal while the crocodile gets clean teeth．
