已知一个正方形的水平放置直观图(用斜二测画法)是有一边长为4的平行四边形,则此正方形的面积是______。 答案:16或64。 Some time ago, a friend of mine who worked in a part of the city I didn't know very well invited me to call on him. It took me hours to get there and I took great trouble to find a proper spot to park my car. As I was already three quarters of an hour late, I parked my car quickly.
At noon, just as I was leaving my friend's office it suddenly struck me that I had no idea where I had parked my car. I could hardly go up to a policeman and tell him that I had lost a small green car somewhere! Walking down street after street, I examined each car closely and was very happy to see a small green car just behind an old car. But how disappointed I was to discover that though the car was exactly like my own, it belonged to someone else! Feeling quite tired now, I went off for lunch. Some time later, I left the restaurant and walked down the street. Turning the corner, I nearly jumped for joy: my car was right in front of me, and there was no problem this time.
To tell the truth, driving in a crowded city is far from being a pleasure and it is much easier to walk than to drive.
