When an ant dies, other ants move the dead insect out. Sometimes, the dead ant get moved away very soon—within an hour of dying. This behavior is interesting to scientists, who wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead—take me away.”
But there’s a twist to Choe’s discovery. Choe says that the living ants—not just the dead ones —have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it’s telling other ants that it’s dead.
What keeps ants from dragging away the living ants? Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, “Wait—I’m not dead yet.” So Choe’s research turned up two sets of chemical signals in ants: one says, “I’m dead,” and the other set says, “I’m not dead yet.”
Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive.
Choe suspects that when an Argentine ant dies, the chemical that says “Wait- I’m not dead yet” quickly goes away. Once that chemical is gone, only the one that says “I’m dead” is left. “It’s because the dead ant no longer smells like a living ant that it gets carried to the graveyard, not because its body releases new unique chemicals after death,” said Choe. When other ants detect the “dead” chemical without the “not dead yet” chemical, they drag away the body.
Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests.
The ants’ removal behavior is important to the overall health of the nest. “Being able to quickly remove dead individuals and other possible sources of disease is extremely important to all animals living in societies, including us,” says Choe. “Think about all the effort and money that we invest daily in waste management.”

We can see how the product life cycle works by looking at the introduction of instant coffee. When it was introduced, most people did not like it as much as "regular" coffee and it took several years to gain general acceptance (introduction stage). At one point, though, instant coffee grew rapidly in popularity and many brands were introduced (stage of rapid growth). After a while people became attached to one brand and sales leveled off (stage of maturity). Sales went into a slight decline when freeze-dried coffees were introduced (stage of decline).
　　The importance of the product life cycle to marketers is this: different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for new users and market sections. Do you know, for example, that the backpacks that so many students carry today were originally designed for the military?
　　Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.
　　Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to recapture（夺回） world markets. Note, also, how auto manufacturers once changed styles dramatically from year to year to keep demand from falling.

　 A. increasing usage among students B. pleasing the young as well as the old
　 C. exploring new market sections D. serving both military and civil needs
50. In order to recover their share of the world market, U.S. auto makers are _______ .
　 A. improving product feature B. making their products better

A new study of 8,000 young people in the journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love（早恋）may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.
The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won’t tell that to their parents.
Dr. Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendship and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.
Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity（成熟）gives us a chance to avoid its bad side effects.

If Barack Obama's wife and kids thought they'd be getting his undivided attention during their long-awaited summer holiday, perhaps they should think again.
The US President kicked off his vacation by revealing that, in addition to endless games of tennis and golf, he plans to spend the week ploughing through five books, weighing in at an astonishing 2,300 pages. His summer reading list, unveiled(透露) by the White House, contains two heavyweight works of non–fiction and three novels.
On top of the president’s table is Hot, Flat and Crowded, by New York Times columnist, Thomas Friedman. Subtitled "why we need a green revolution", it makes a leftish（左倾的） call to arms regarding the future of the planet.
Mr Obama's second choice is historian David McCullough's biography of John Adams, the often under-rated second US president, who was the subject of an award-winning HBO docu-drama（纪实剧）last year.
The novels include two crime thrillers: Richard Price's Lush Life, and The Way Home, a novel by George Pelecanos set in Washington, DC – which, much like Obama's best-selling autobiography（自传）, explores the relationship between a father and his son.
Completing the set is the novel Plainsong, by a little-known writer called Kent Haruf. Set in a small town on the Colorado plains, its existence on the reading list may reassure voters that Middle America has not been ignored by their commander-in-chief.
Publishers are keeping an eye on whether the famous "Obama bounce" – which has helped sales at the first family's favourite clothes stores, such as J Crew – will continue to apply to their troubled industry. The President's endorsement（认可） is said to have lifted sales of Joseph O'Neill's novel Netherland about cricket in Holland and New York last year.
Given that President Obama has already spent a portion of his week so far playing golf, beating Michelle at tennis, and visiting friends, questions will inevitably(不可避免地) be asked about his ability to put any dent（挫伤） at all in the ambitious reading list.
To finish all five books, he would have to manage more than 300 pages every day – quite an "ask" when a small portion of his time must also be spent running the country.

Fifty–eight percent of the teachers interviewed in the Association of Teachers and Lecturers (ATL) questionnaire had come across copying among their pupils. Gill Bullen from Itchen College in Southampton, for example, said, "Pieces handed in by two students were identical and significantly better than either of them could have done. Not only that, the essays handed in didn't quite answer the title question I had set". A teacher from Leeds said, "I had one piece of work so bravely cut and pasted that it still contained ads from the web page."
Connie Robinson from Stockton Riverside College said, "With less able students it is easy to spot copying as the writing style changes in the middle of the assignment, but with more able students it is sometimes necessary for tutors to carry out Internet research to identify the source of the copy."
Mary Bousted, general secretary of the ATL, said," Teachers are struggling under a mountain of cut-and-pasting to spot whether work was the student's own or copy." She called for policies to stop copying, and asked for help from exam boards and the government in providing resources and techniques to detect cheats.
But there was another side. "I have found once students clearly understand what copying is, its consequences and how to reference correctly so they can draw on published works, copying becomes less of a problem," said Diana Baker from Emmanuel College, Durham.
"I think the majority of students who engage in copying do it more out of ignorance than the desire to cheat. They really want to succeed on their own."
