答案：A
Passage Three
In her international bestselling Talk to the Hand,author Lynne Truss.argues that common
courtesies such as saying“Excuse me”are practically extinct.There are certainly plenty who
would agree with her.
Is it really true?We decided to find out by experiments.In dozens of American cities,our
reporters performed two experim6rits：“door tests”(would anyone hold one open for them?)；
and“document drops”(who-would help them retrieve a pile of“accidentally”dropped papers?).
Along the way,the reporters encountered all types：men and women of different races,ages，professions,and income levels.
While 90 percent of the people passed the door test，only 55 percent passed the document
drop.Are people less likely to help others when doing so takes extra effort or time? Not always，
he reporters found.Take the pregnant woman who thought nothing of bending down to help us with
our papers.Or the woman named Liz who balanced two coffees，her keys and her wallet on a
takeout tray with one hand，while picking up papers off the wet pavement with the other.Her
reason for helping?“I was there,”she said.
Overall，men were the most willing to help，especially when it came to document drops.In those，men offered aid 63 percent of the time，compared to 47 percent among women.Of course，men weren’t entirely democratic about whom they’d help.All of them held the door for the
female reporter,and were more than twice as likely to help her pick up fallen papers than they were
to help our male reporter.
