Dolphins and sharks are showing up in surprisingly shallow water just off the Florida coast. Mullets, crabs, rays and small fish gather by the thousands off an Alabama pirer. Birds covered in oil are crawling deep into marshes(沼泽), never to be seen again.
Marine scientists studying the effects of the BP disaster(英国石油公司漏油事件)are seeing some strange phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters along the coast in a trend that some researchers see as a potentially troubling sign. The animals' presence close to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run out of oxygen. Also, the animals could easily be captured by their enemies.
The nearly two-month-old spill(漏油)has created an environmental disaster in US history as tens of millions of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try to understand the effects on thousands of species of marine life.
For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate islands and mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking(嬉戏)in the oily sheen(光泽)and oil-tinged pelicans feeding their young. But they spotted no dead animals.
"I think part of the reason why we're not seeing more yet is that the impacts of this crisis are really just beginning," Greenpeace marine biologist John Hocevar said.
The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will help determine how much BP pays in damages.

Parents who feel disappointed at their teenagers’ failure to pay attention in class, and inability to sit quietly long enough to finish homework or plan ahead, should take solace. Their children are not being lazy or careless, according to new research.
The research has found that teenagers’ brains continue developing far longer into adulthood than we used to think. Teens may look like young adults but their brain structure is similar to that of much younger children.
“It is not always easy for teens to pay attention in class without letting their minds wander, or to ignore distractions from their younger brothers or sisters when trying to solve a maths problem,” said Dr Iroise Dumon-theil. “But it’s not the fault of teenagers that they can’t pay attention and are easily distracted. It’s to do with the structure of their brains. Teens simply can’t think as well as an adult.”
The research showed that the brain of a teenager works less effectively than that of an adult. “We knew that the front of the brain of teens functioned in a chaotic (混乱的) way but we didn’ t realize it continued until the late 20s or early 30s,” said Dr Sarah-Jayne Blakemore, who led the research.
Chaotic thought patterns are a result of teenagers’ brains containing too much grey matter — the cell bodies and connections which carry messages within the brain. As we age, the amount of grey matter in our brain reduces.
“What our research has shown is that there is simply too much going on in the brains of teens,” said Blakemore. “The result is that their brain energy and resources are wasted and their decision-making process is badly influenced. Adults, on the other hand, have less grey matter. This means that the brain works far more effectively.”
【小题1】The underlined word “solace” in Paragraph 1 may mean _____.
| A. notice | B.medicine | C.comfort | D.action |
| A.teens’ brains continue to do much needless work |
| B.the grey matter in young children’s front brain becomes active |
| C.people are not likely to be distracted until their late 30s |
| D.adults are more independent than teens |
| A.It makes us always feel disappointed. |
| B.It makes us more intelligent. |
| C.It had a bad effect on the growth of teens. |
| D.It had a bad effect on decision-making. |
| A.Teens have different brains from those of children. |
| B.Adults work more effectively than teens. |
| C.Grey matter makes teens unable to pay attention. |
| D.Brain energy is wasted in the brain’s activity. |
