At a psychology conference in England years ago, a woman said to me: “I’ll knock you up in the morning.” I was taken aback by her strange suggestion, but it occurred to me that I might not have understood what she really meant. As it turned out, what she had meant was, “I’ll knock on your door in the morning so that we can meet for breakfast to discuss the panel we’re on.”

This example of the difference in the meaning of “knock you up” in British and American English shows the complicated situations that can result from cultural misunderstandings. A cultural misunderstanding occurs when something — a word, gesture, object, social context, or almost anything you can think of — has a different meaning in two cultures. Sometimes the misunderstandings get resolved, sometimes they lead nowhere, and sometimes they can become the starting point of something much more extreme, from love to war.

Race is one area where cultural misunderstandings are common. We Americans tend to assume that racial categories are biological rather than social, so it may not occur to us that people from other cultures have a different set of racial concepts and classify themselves and us differently. Some African Americans complain that certain immigrants from other countries, such as Haiti or Jamaica, “act as if they aren’t black.” The cultural misunderstanding is that, in the immigrants’ countries of origin, they would never describe themselves as “black”. This doesn’t mean that they think they are white. It just means that their cultures have more categories, like marabou or grimaud in Haiti, or fair or brown in Jamaica, than are used in the United States. Meanwhile, white people in America, unaware of this cultural diversity, sometimes refer to all darker-skinned people as “black” without realizing that an issue exists.

Resolving cultural misunderstandings can clear the air or even lead to laughter. Sometimes, though, when it comes to race, unidentified cultural misunderstandings can create tension, unhappiness and distrust.

单项选择题

The human Y chromosome—the DNA chunk that makes a man a man—has lost so many genes over evolutionary time that some scientists have suspected it might disappear in 10 million years. But a new study says it’ll stick around.
Researchers found no sign of gene loss over the past 6 million years, suggesting the chromosome is "doing a pretty good job of maintaining itself," said researcher David Page of the Whitehead Institute for Biomedical Research in Cambridge, Mass.
That agrees with prior mathematical calculations that suggested the rate of gene loss would slow as the chromosome evolved, Page and study co-authors note in Thursday’s issue of the journal Nature. And, they say, it clashes with what Page called the "imminent demise" idea that says the Y chromosome is doomed to extinction.
The Y appeared 300 million years ago and has since eroded into a dinky chromosome, because it lacks the mechanism other chromosomes have to get rid of damaged DNA. So mutations have disabled hundreds of its original genes, causing them to be shed as useless. The Y now contains only 27 genes or families of virtually identical genes.
In 2003, Page reported that the modern-day Y has an unusual mechanism to fix about half of its genes and protect them from disappearing. But he said some scientists disagreed with his conclusion. The new paper focuses on a region of the Y chromosome where genes can’t be fixed that way.
Researchers compared the human and chimpanzee versions of this region. Humans and chimps have been evolving separately for about 6 million years, so scientists reasoned that the comparisons would reveal genes that have become disabled in one species or the other during that time.
They found five such genes on the chimp chromosome, but none on the human chromosome, an imbalance Page called surprising. "It looks like there has been little if any gene loss in our own species lineage in the last 6 million years," Page said. That contradicts the idea that the human Y chromosome has continued to lose genes so fast it’ll disappear in 10 million years, he said. "I think we can with confidence dismiss … the ’imminent demise’ theory," Page said.
Jennifer A. Marshall Graves of the Australian National University in Canberra, a gene researcher who argues for eventual extinction of the Y chromosome, called Page’s work "beautiful" but said it didn’t shake her conviction that the Y is doomed.
The only real question is when, not if, the Y chromosome disappears, she said. "It could be a lot shorter than 10 million years, but it could be a lot longer," she said.
The Y chromosome has already disappeared in some other animals, and "there’s no reason to expect it can’t happen to humans," she said. If it happened in people, some other chromosome would probably take over the sex-determining role of the Y, she said.

The word "dinky" ( line 1, paragraph 4) most probably means
[A] dirty. [B] tricky. [C] mai-functional. [D] defective.
