Within the first month of their lives, babies responses to the sound of the human voice will be different

2、from their responses to other sorts of auditory stimuli. They will stop crying when they hear a person talking, but not if they hear a bell or the(5) sound of a rattle. At first, the sounds that an infant notices might be only those words that receive the heaviest emphasis and that often occur at th

3、e ends of utterances. By the time they are six or seven weeks old, babies can detect the difference between syllables pronounced with rising and falling inflections. Very soon, these differences in adult stress and intonation can influence babies emotional states and behavior. Long before they(10) d

4、evelop actual language comprehension, babies can sense when an adult is playful or angry, attempting to initiate or terminate new behavior, and so on, merely on the basis of cues such as the rate, volume, and melody of adult speech. Adults make it as easy as they can for babies to pick up a language

5、 by exaggerating such cues. One researcher observed babies and their mothers in six diverse cultures and(15) found that, in all six languages, the mothers used simplified syntax, short utterances and nonsense sounds, and transformed certain sounds into baby talk. Other investigators have noted that

6、when mothers talk to babies who are only a few months old, they exaggerate the pitch, loudness, and intensity of their words. They also exaggerate their facial expressions, hold vowels longer, and emphasize certain words.(20) More significant for language development than their response to general i

7、ntonation is observation that tiny babies can make relatively fine distinctions between speech sounds. other words, babies enter the world with the ability to make precisely those perceptual discriminations that are necessary if they are to acquire aural language. Babies obviously derive pleasure fr

8、om sound input, too: even as young as nine months(25) they will listen to songs or stories, although the words themselves are beyond their understanding. For babies, language is a sensory-motor delight rather than the route to prosaic meaning that it often is for adults.According to the author, why

9、do babies listen to songs and stories, even though they cannot understand themAThey understand the rhythm.BThey enjoy the sound.CThey can remember them easily.DThey focus on the meaning of their parents words. 2.

13、sible to terraform Mars by making use of the planets own resources and by introducing genetically altered life from Earth. They hope these actions will speed up the terraforming process, not just by adapting Mars to support Earth-life, but also by adapting Earthlife to exist on Mars. These experts t

14、hink they can use the Martian geology itself to jump-start the planet. The theory is that detonation of thermonuclear devices deep in the Martian mountains will trigger eruptions of hot magma that would melt the frozen atmosphere, thereby releasing the components necessary for life. 6.For generation

15、s, Native Americans used myths and legends to explain the mysterious world around them. One such etiological myth originated with the Cherokee. According to the tale, at one time, far in the past, animals, birds, fishes, and even insects were able to communicate with one another. When humans arrived

16、, however, life became more difficult because the creatures habitats began to shrink. In order to protect themselves, the creatures decided to introduce disease to humans. The plant world, however, took sympathy upon the Cherokee and so provided a remedy for each of the diseases created by the creat

21、Western European nations, the law is seen as rigid and not open to interpretation.

40、ses state-of-the-art instruments to provide amazing views of the universe that cannot be matched by ground-based telescopes.
