You don't really need much to start running. Once you have shoes, socks, something to listen to and something to clock your time, you're just about set. 1. Whether you choose a standard watch, a high-tech GPS watch or your iPhone doesn't matter.
1. Choose a shoe
Don't be influenced by brand names. Instead, try on four or five running shoes, jog around the store and let your feet decide. In a sweeping review of the science on running shoes and injuries, researchers found that the most important feature of a running shoe is — comfort. That's it. 2.
2. Choose a pair of socks
3. Blisters from unsuitable socks are painful and could affect you for days. You want a breathable, comfortable sock. Some running socks are made from a special material that draws moisture (湿气) away from your feet.
Look for a sock without thick (or any) seams (缝) and decide if you want a no-show sock or one that covers the back of your ankle. 4. Test them out to see how they perform when you run and sweat before buying more pairs.
3. Choose a playlist
Running should feel like a reward. If you're a runner who likes the quiet of running, then pick a quiet path and go run. But many people like a combination of upbeat music or books on tape to accompany them on the run. 5. They often read their own audio books and leave you laughing so much you forget the pains of running.
A. Choose a shoe that feels good.
B. Consider trying books by comedians.
C. Here's how to pick the right running equipment.
D. It can prevent bacteria from accumulating on your feet.
E. Try socks on in the store, and pick one or two that you like.
F. While most runners focus on shoes, socks can be important too.
G. When it comes to the timing tool, just pick the one that works for you.

Starting the day on an egg could keep your blood pressure under control, research suggests. Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs.
The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes (酶) they produce a protein that acts in the same way as Ace inhibitors, but more work is needed to show the effects outside a lab and in the human body.
Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg. They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on increasing heart disease risks.
Researcher Professor Bruce Griffin, from the University of Surrey, said, "The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected. The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs. The UK public do not need to be limiting the number of eggs they eat. They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods."
The British Heart Foundation dropped its three-egg-a-week limit in 2005. However, almost half of Britons believe the limit still applies.
1.From the text we know that Ace inhibitors are ________.
A. a kind of protein B. a kind of food
C. a kind of medicine D. a kind of illness
2.According to what Professor Bruce said, eggs ________.
A. are the most nutritious food
B. can be included in a healthy diet
C. have no effect on blood cholesterol
D. are forbidden to be eaten in the UK
3.We can infer from the text that ________.
A. stomach enzymes mixed with eggs can cure heart diseases
B. drugs to lower blood pressure will be replaced by eating eggs
C. most Britons agree the three-egg-a-week limit should be dropped
D. about 50% of Britons think eating an egg a day is bad for their health
4.The text is meant ________.
A. to introduce a medicine made from eggs
B. to introduce scientific findings about eggs
C. to tell people how to lower their blood pressure
D. to advise people to eat as many eggs as possible
