Some people will do just about anything to save money. And I am one of them. Take my family's last vacation. It was my sixyearold son's winter break from school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York, so I had to get back. But that didn't mean my husband and my son couldn't stay. I took my ninemonthold and took off for home.
The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport to “earn” more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I'm a bad mother and not such a great wife either. But as a bigtime bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made a living looking for the best deals and exposing (揭露) the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.
I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.

The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.What is the author's opinion on cramming?

| B．It's helpful only in a limited way. |
| C．It's possible to result in poor memory. |

Much later that night, the question of why I'd stopped for that light came back to me. I think I stopped because it's part of a contract(契约)we all have with each other. It's not only the law, but it's an agreement we have, and we trust each other to honor it: we don't go through red lights.
Trust is our first inclination(倾向)．Doubting others does not seem to be natural to us. The whole construction of our society depends on mutual(相互)trust, not distrust. We do what we say we'll do; we show up when we say we'll show up; and we pay when we say we'll pay. We trust each other in these matters, and we're angry or disappointed with the person or organization that breaks the trust we have in them.The event made the author strongly believe that________.
| A．traffic rules may be unnecessary |
| B．doubting others is human nature |
| C．patience is important to drivers |
| D．a society needs mutual trust |
