Your life depends on heat. In fact, every living thing depends on it. (28) Without heat, every living thing would be frozen to death. All living things get their heat from the sun, which provides the conditions in which life is possible.
Since the dawn of history, man has been able to make his own heat. He has been able to release the sun's heat that is trapped in things such as wood, coal and oil. And he has been able to use this heat.
Heat has made civilization possible. With heat, man could melt metals. As man learned to use metals and fuels, industries grew. As a result, engines were invented. These are machines that change heat energy into mechanical energy. Engine can do the work of many men. Without engines industrial civilization is impossible.
Yet when the first engines were built in the 17th century, men were still wondering about the nature of heat. "What is it?" they asked. Not until the early years of 19th century did they find the right answer.
In everyday usage, "hot" means______.
A.the weather is fine and it is in summer
B.one has a temperature
C.having a great deal of heat
D.having very little heat

"It wasn't clear how long children in the first year of life could retain a memory of an event," Liston says. We were interested in testing the hypothesis that neurological developments at the end of the first year and the beginning of the second would result in a significant Enhancement in this kind of memory.
Liston showed a simple demonstration to infants ages 9, 17, or 24 months old. The test results showed a huge difference between the test children Who had been 9 months old when they saw the first demonstration and those who had been older. "Whereas 9-month-olds don't I really remember a thing after four months, 17-and 24-month-olds do," Liston says. "Something is happening in the brain between 9 and 17 months old that enables children to encode these memories efficiently and in such a way that they can be retained and retrieved after a long period of time," Liston says. Researchers believe that changes in certain regions of the brain's frontal lobe and the hippocampus, which axe associated with memory retention and retrieval, drive the rapid expansion of childhood recall. Previous studies have shown that the frontal lobes in humans begin to mature during the last quarter of the first year of life.
Liston's work may help explain why adults can rarely remember anything from before their second birthday or so. Most people simply accept this "infant amnesia" as a fact of life. "But it's not clear why a 40-year-old has plenty of memories for something that happened 20 years ago, but a 20- year-old has basically no memories for something that happened when he was 2 or 3 ," Liston says. He suggests that the same brain mechanisms that were not yet able to encode long-term memories in 9-month-olds may also play some role in adults' inability to remember events of infancy. Researchers still need to look at other areas of cognition -- such as what role language ability plays in memory -- to really fully understand why people can' t remember anything that happened before 2--3 years of age. But one thing is clear: When l-year-old Snookums claims he doesn't remember breaking the heirloom chitin five months ago, he's almost surely telling the truth.
Conor Liston ______.
A.has only a vague understanding of infants' poor memory
B.has found something more about the origin of long-term recall
C.has detected the regions of the brain responsible for memory-processing
D.has established a theory about memory development
