Research scientists at the institute note that babies are strongly influenced by their environment. They say a baby will smile if its mother does something the baby likes. A baby learns to get the best care possible by smiling to please its mother or other caregivers(照料者). Its mother or other caregivers then understand(s) its information. This is how babies learn to connect and communicate people. The American researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers. A study last month from the Netherlands found evidence that unborn babies can remember sounds. This study was very valuable indeed. Dutch researchers studied almost one hundred pregnant(怀孕的) women. They played sounds to the growing fetus(胎儿) and watched its movements with ultrasound(超声) devices. They found that by thirty weeks of development the fetus could remember a sound for ten minutes. By the thirty-fourth week, the fetus could remember the sound for four weeks.

These memories of mine have been collected slowly, over a period of years. Some readers, finding them in a magazine, have taken them for stories.
