【简答题】
It doesn’t come as a surprise to you to realize that it makes no difference what you read or study if you can’t remember so. You just waste your valuable time. Maybe you have already discovered some clever ways to keep yourself against forgetting.
One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading. You remember better what you read while you know why you’re reading.
Why does a clerk in a store go away and leave you when your reply with her offer to help is" No, thank you. I’m just looking" Both you and she know that if you aren’t sure what you want, you are not likely to find it. But suppose if that you say instead, "Yes, thank you. I want a pair of sun glasses. "She says," Right this way, please. "And you and she are off—neither eager to look for exactly what you want.
It’s quite the same with your studying. If you chose a book at random, "just looking" for nothing in particular, you are likely to get just that—nothing. Moreover if you do know what you want, you are almost sure to get it. Your reasons will vary; they will include reading or studying" to find out more about", "to understand the reasons for", "to find out how". A good student has a clear purpose or reason for what he is doing.
This is the way it works. Before you start to study, you say to yourself anything like this, "I’m going to skim this stow to see what life is like in medieval England. " Because you know why you are reading or studying, you relate information to your purpose and remember it better.

【单选题】Nearly 2, 000 feet in the air, above where the Mississippi River flows into the Gulf of Mexico, the approaching storm is in full view; millions of gallons of wind-swept crude oil, in streaks that arc ...
A.
At one point, the plane passed over a tiny island filled with pelicans. Louisiana’s state bird. Booms, which are meant to help block off, retain and skim off the oil, have been placed around the island. But they are, it seems, of little use. In various sections, they have been pushed by wind and water onto the shoreline. Experts say many types of booms only work in calm weather conditions. The past few days have been marked with fierce winds and rain.
B.
Booms arc the most common containment method being used so far. But Barry Kohl, an adjunct professor of earth and environmental sciences at Tulane University, in New Orleans, says that even in the best weather conditions, skimming will remove only between 10% and 15% of the oil from the water’s surface. Another strategy that officials are trying: spraying dispersants — chemicals used to break up the oil — onto the water’s surface, or injecting it thousands of feet below water. The dispersants cause the oil to sink to the bottom of the sea. But experts warn that dispersants will also kill the plankton on which shrimp and fish depend for food. So far, the authorities haven’t clarified what chemical dispersants are being used. "We don’t know what happens to the oil once it’s dispersed, "Kohl says.
C.
"You see the stuff to the left" Panepinto asked, pointing to the long red and orange, sometimes brown, streaks. "That there is the oil. "The crude, which comes out of the wells black, has essentially emulsified, partly from having been exposed to the sunlight for so much time. By the time it reaches the shore, probably in the next day or so, it will likely be brown, like chocolate. Each day, the streaks will become less and less of a sheen, and more of a gummy substance. From the plane, you could see that it was approaching a massive school of flounder. "It’s like they’re swimming toward death, " Panepinto said. On the other side of what looked like a massive contagion were the shrimpers, lowering a boom onto the water. "What they’re doing is ’hopeless’ , " Michael Brune, executive director of the Sierra Club, says of the shrimpers.
D.
Minutes later, the plane was flying over the man-made Mississippi River Gulf Outlet, created nearly half a century ago partly to give large shipping vessels another route to travel between the Gulf of Mexico and New Orleans. Much of the water that flooded New Orleans in the wake of Hurricane Katrina came from MRGO. Much of the nearby marsh was destroyed — and with it, one of the last lines of defense for New Orleans against the Gulf’s water. If and when the oil hits land, it may kill much of the remaining vegetation that holds the soil together — one more reason New Orleans and folks on dry land are concerned about the spill’s effects.
