B. Why scientists are interested in blue holes.        
C. How a blue hole comes into being.
D. Blue holes exploring is becoming popular.
E. Rules to obey when diving into blue holes.
F. The general definition of a blue hole.
【小题1】______________
A blue hole is a flooded sea cave with a hole that opens up at the land's surface. These cave systems form in carbonate rock, often on islands. Some blue holes have very special rock formations and water chemistry. Far below sea level, they contain some of the harshest environments on Earth, with no oxygen and no light. Yet these areas are filled with life forms that have adapted to the extreme conditions.
【小题2】___________
Blue holes get their name from the color some have when seen from the air. The color is usually a reflection of the sky on the water. Blue holes are the result of erosion in which water breaks down rock. Rain falling thousands of years ago contained chemicals which slowly wore away at the limestone landmass. These holes later filled with sea water as the sea level changed. The rising and falling of sea levels and the mixture of salt and fresh water further wore away at these cave formations.
【小题3】___________
These flooded cave systems can be found in the ocean, or they can be found inland. Ocean caves are affected by tides, so they always have water movement. But blue holes on land are very still. They have several layers of water, chemicals, and bacteria. The top layer of fresh water comes from rainfall. This layer acts like a cap on top of the layered mixture, and keeps out oxygen from the atmosphere. The fresh water floats on a denser layer of saltwater. Underneath this is a layer of poisonous hydrogen sulfide, produced by bacteria living in the water. Underneath this layer is anoxic seawater -- water that does not contain any oxygen.
【小题4】___________
Information gathered from these blue holes is helping scientists to increase their understanding of biology, archaeology and geology. But exploring these blue hole environments brings danger as well as discovery. Scientists are interested in these caves because oxygen-free conditions there are similar to those on Earth long ago, before oxygen existed on our planet. But there are many difficulties involved in diving into blue holes.
【小题5】___________
One reason blue holes have not been fully explored is that they can be extremely dangerous. There are many safety rules that divers must follow to help ensure their survival. First, divers must have training and experience to swim in these caves. Divers who explore a cave for the first time must establish a thin rope called a guideline. This line helps them to safely enter and exit the cave without getting lost.

Humans and dogs have been working together for thousands of years, and some scientists even believe the two species have been living with one another for thousands of years． While having a dog will not improve your health if you never wanted a dog in the first place, dog lovers can benefit from living with them．
【小题1】      
Most of us know the benefits of exercise, but it can be a struggle to find the motivation to get up and get moving everyday． A dog provides strong motivations, and can make your daily walk or run less lonely and more fun．Moreover, you'll bum extra calories when helping your dog walk and doing brief training exercises with your dog． For some people, going for walks alone is scary, but a dog can make runs and walks feel more secure．l know that with Ranger．I have to walk him every day, and he's always ready each morning．Sometimes we even have an afternoon or early evening walk, which is better for my health．
【小题2】       
There's no doubt that dog ownership does come with some stresses, from making sure you've applied their weekly bath to worrying if your dog will get along with the other dogs at the dog park． But the benefits of pet ownership more than outweigh these small stresses． Research shows that a few minutes spent petting an animal． lowers blood levels of the stress hormone, which contributes to tiredness, weight gain and aging, and your pet can help kill its negative effects． A few minutes playing with your dog every day also releases powerful ¨feel-good" hormones that continue to function in the bloodstream．
【小题3】       
Many people living alone worry about thieves, and a dog can help give owners a sense of security． Thieves are less likely to break into a house with a barking dog, and your dog can help you feel less lonely whether you're just spending the night by yourself or living alone long-term．If your dog is older and struggles to move around, you can still rest easy knowing that your dog will get to a robber before you do．
【小题4】       
People who have regular positive interactions with others tend to live longer and be happier, and pets provide you with a valuable opportunity to meet and interact with other people． Even if you're shy, it's easy to strike up a conversation with another person if you're both talking about your animals． Visits to the dog park and meet--ups with other pet owners also provide pet owners with opportunities for interactions．If you're still anxious about meeting new people, consider joining a message board or online group for people with similar pets to yours． You'll quickly find yourself making new friends in addition to learning a lot about your best friend - your pet!
【小题5】      
In a fast-paced, high-stress world, depression and anxiety are at an all-time high． But pet owners have fewer mental illnesses, and animals are even used as treatment for people suffering from mental illness． If you struggle with depression, an animal can help you avoid such problems． The exercise and stress release you get from spending time with your pet may even reduce the effects of depression． Dog owners are also less stressed than people who don't own dogs, and reduced stress is strongly related with lower blood pressure, a longer life span, greater happiness and improved health．

Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided.   【小题1】 
Write it out
You can also check a math problem by writing everything out on paper.   【小题2】  Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
 【小题3】 
Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.
Plugging in
You may find that a variable(变量) isn’t good enough or have a problem where you have to solve for a variable.   【小题4】  This is the only real way to assure yourself that the answer you’ve found is correct.
Check for a reasonable answer

A. Attention must be paid to environmental factors.
B. Principles of curing cancers.
C. It will take long to find perfect cures.
D. An important discovery in the research.
E. The causative factor of cancer is very clear.
F. The survival rate differs among patients with various cancers.
【小题1】___________
“I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,” says microbiologist Robert Weinberg, an expert on cancer. “But,” he cautions, “some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available. ”
【小题2】____________
This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2020, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging—13 percent for lung cancer, and 2 percent for cancer of the pancreas (胰腺) .
【小题3】___________
With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes, are inactive in normal cells. Anything from universe rays to radiation to diet may activate an inactive gene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous.
【小题4】____________
The exact process involved is still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. “Changes are a normal part of the evolutionary process,” says oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, “We can’t prepare a medicine against universe rays.”
【小题5】____________
The prospects for cure, though still distant, are brighter. “First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells, which are always responsible for at least part of the trouble. If we can understand how cancer works, we can reduce its action. ”
