The Greatest Mystery Of Whales
The whale is a warm-blooded, air-breathing animal, giving birth to its young alive, sucking them-and, like all mammals, originated on land. There are many(51)of this. Its front flippers (鳍状肢), used for steering and stability, are traces of feet.
Immense strength is(52)into the great body of the big whales, and in fact most of a whale's body is one gigantic muscle. The blue whale's pulling strength has been estimated(53)400 horsepower. One specimen was reported to have towed (拖) a whaling vessel for seven hours at the(54)of eight knots (节).
An angry whale will(55)a ship. A famous example of this was the fate of whaler Essex,(56)was sunk off the coast of South America early in the last century. More recently, steel ships have(57)their plates buckled (使弯曲) in the same way. Sperm whales (抹香鲸) were known to seize the old-time whaleboats in their jaws and crush them.
The greatest(58)of whales is their diving ability. The sperm whale dives to the bottom for his(59)food, the octopus (章鱼). In that search he is known to go as far down as 3,200 feet, where the(60)is 1,400 pounds, to a square inch. Doing so he will(61)underwater long as one hour. Two special skills are involved in this: storing up enough(62)(all whales are air-breathed) and tolerating the great change in pressure. Just how he does it scientists have not (63) . It is believed that some of the oxygen is stored in a special(64)of blood vessels, rather than just held in the lungs. And it is believed that a special kind of oil in his head is some sort of compensating mechanism that(65)adjusts the internal pressure of his body. But since you can't bring a live whale into the laboratory, for study, no one knows just how these things work.

Most people don't enjoy facing the difficult situations that sometimes occur with coworkers in the workplace. Such situations may arise from honest disagreements over design or engineering issues, personnel or benefits matters, management decisions or actions, or from any other situation where human impressions and objectives differ.
There could be double trouble for engineers who are more likely to feel at home with electrons and bytes(信息组), and behave in highly predictable ways, than with coworkers, who often appear arbitrary and unpredictable. For those of us who have internalized the strict and measurable rules of the physical world, dealing with other people can be both disappointing and frustrating.
Yet how you manage situations of conflict with your coworkers could have a significant impact on your career, often even more than your engineering prowess or your design skills. Those who deal successfully with potential conflicts are far more likely to receive added responsibilities and promotions, in addition to the pay increases and respect that come with them. On the other hand, not dealing successfully with conflict can potentially relegate you to a career backwater, with technical challenges and high pay passing you by.
Why is dealing with conflict an important skill today？ It's primarily because there's more of it now than in the past. Workers of all types are more likely to speak up for their own ideas or actions, rather than follow the dictating corporate chain of command. Conflict also sometimes arises as a result of unclear company goals, or when those goals aren't shared equally by all. Rather than working for a single common good, employees and managers seek individual goals, such as promotion, job security, experience, money, and even the proverbial free lunch.
Not only is actual conflict greater today, but even the potential for interpersonal conflicts in the workplace is far greater than at any time in the past. One reason for this is increased time-to-market pressures. The need to rapidly make decisions, establish an engineering direction, and meet project milestones adds elements of tension and stress to an already difficult endeavor.
This makes the workplace a potential minefield for interpersonal conflict. It's especially apparent to an engineer in a position of responsibility, like a project leader or an engineering manager. For an engineer who must work with others to complete a project, the need to manage conflict can spell the difference between success and failure.
