Long before they can actually speak, babies pay special attention to the speech they hear around them. Within the first month of their lives, babies' responses to the sound of the human voice will be different 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 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 the 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 develop 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 by exaggerating such cues. One researcher observed babies and their mothers in six diverse cultures and 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 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.
More significant for language development than their response to general intonation is observation that tiny babies can make relatively fine distinctions between speech sounds. In 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 from sound input, too: even as young as nine months 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.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 33 to 38.
Sylvia Earle, a marine botanist and one of the foremost deep-sea explorers, has spent over 6,000 hours, more than seven months, underwater. From her earliest years, Earle had an affinity for marine life, and she took her first plunge into the open sea as a teenager. In the years since then she has taken part in a number of landmark underwater projects, from exploratory expeditions around the world to her celebrated “Jim dive” in 1978, which was the deepest solo dive ever made without cable connecting the diver to a support vessel at the surface of the sea.
Clothed in a Jim suit, a futuristic suit of plastic and metal armor, which was secured to a manned submarine, Sylvia Earle plunged vertically into the Pacific Ocean, at times at the speed of 100 feet per minute. On reaching the ocean floor, she was released from the submarine and from that point her only connection to the sub was an 18-foot tether. For the next 2½ hours, Earle roamed the seabed taking notes, collecting 15 specimens, and planting a U.S. flag. Consumed by a desire to descend deeper still, in 1981 she became involved in the design and manufacture of 20 deep-sea submersibles, one of which took her to a depth of 3,000 feet. This did not end Sylvia Earle’s accomplishments.
The main purpose of this passage is _______.
A.to explore the botany of ocean floor
B.to present a short biography of Sylvia Earle
C.to provide an introduction to oceanography
D.to show the historical importance of the Jim dive
