[单项选择]How long is it since you last went out for a walk
Three days Three weeks Three years
Well, who has time for that kind of thing nowadays
Your doctor may tell you to get more clean air.
Your friends may tell you to get more exercises.
Your wife may tell you to find something cheap to do.
You would go out and walk for miles, except for one thing,
Walking is boring.
But now science has come to help yon.
Now there is a reason for going out in the countryside.
No more worry about not knowing where to go.
Now the countryside is a forever pleasure.
What could be more interesting than looking for buried (埋藏的) gold while walking
So now have a look at the new Sherlock Metal (金属) Detector (探测器).
When you are walking with it, you will be very likely to find gold.
Buy yourself a Sherlock Metal Detector, and you’ll find yourself out in the open air for hours at a time.
Metal detecting is the great new hobby.

So as he began to walk, he felt very uncomfortable (不舒服). When he was just out of the house, he turned to his son and said, "Why should one of my legs be longer than the other today "
The son looked at his father’s legs carefully as he was walking and then laughed," Oh, no, Daddy, your legs are all right. You have put on the wrong shoes."

When the son ran back to the house, he found that the other pair was also a pair of wrong shoes.
He had to return to his father with nothing in his hands and said out of breath (气喘吁吁地), "It’s no use changing them, Daddy! The shoes at home were not a pair, either!/
