Judging by the $23 billion it earned last year, these should be the best of times for Shell, the Anglo-Dutch energy giant that ranks third among the top five Western oil companies. But Wall Street isn't celebrating. Instead, analysts are worried that buried beneath the record profit figures are worrying signs of a business in decline.
That's because Shell hasn't been able to find nearly as much oil and gas as it's now pumping out of the ground. In fact, it hasn't even come close—replacing only 60% to 70% of what it produced in 2005 and only 19% in 2004. Shell has had reserve problems for years—a controversy over improperly booked assets forced it to reduce estimated reserves by roughly 30% and led to the resignation of its CEO, Phil Watts, in 2004. But what's troubling now is that Shell is falling way behind rivals like Exxon and BP despite spending billions more each year on exploring and drilling new wells. Last year Exxon replaced 112% of production; BP came up with 95%. "I have never seen anything like this," says Fadel Gheit, a veteran energy analyst with Oppenheimer & Co. "Shell used to represent the gold standard in this industry, but lately they can't get their act together."
To be sure, Shell still has huge assets—nearly 12 billion barrels. But in the oil and gas industry, reserve replacement is the best guide to whether a company will be able to maintain-or grow-production in the future. So not replacing what you pump, says longtime industry observer Matthew Simmons, "is like eating your seed corn. If you're not finding new oil, you're just liquidating what you've got." Indeed, Shell's daily production figures have been weak lately, falling 6.7 % in 2005, to 3.52 million barrels a day.
Privately, Shell execs say the company's decision to cut spending for exploration when oil prices bottomed out in the late 1990s is partly to blame for the anemic numbers now. Shell CEO Jeroen Vander Veer insists that projects like those on Sakhalin Island off Siberia and in Nigeria and the Gulf of Mexico will enable the company to start catching up with peers in the years ahead. It won't be easy. "If you're not adding to reserves, you have a problem," says Sanford Bernstein analyst Oswald Clint. "Shell will have to run twice as hard just to stay in place."

Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged？ Judging from the drastic experiment of Frederick Ⅱ in the thirteenth century, it may be. Hop hag to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.
All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, ill the first year of life especially, the capacity to survive is seriously affected.
Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the in fact, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.
Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech tins started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1000 words which he can put into sentences, and at four he knows iris language differs from that of his parents in style. rather than grammar.
Recent evidence suggests that an infant is born with the capacity of speaking. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways.
But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out on- ly the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language.
The purpose of the Frederick Ⅱ's experiment was ______.
A．to prove that children are bom with the ability to speak
B．to discover what language a child would speak without hearing any human speech
C．to find out what role careful nursing would play in teaching a child to speak
D．to prove that a child would be damaged without learning a language
