Passage Two
Regular child care provided outside home or by someone other than the mother does not in itself undermine(削弱) healthy emotional connections between mothers and their 15-month-old infants, according to a long-term national study. The finding holds even if care begins during the first 3 months after birth and runs for 30 hours or more per week.
Among infants who receive unkind and unresponsive care from their mothers, however, the mother-child relationship may be damaged. "This research helps us put apart complexities regarding child care that have not previously been studied in detail." contends Jay Belsky, a psychologist at Pennsylvania State University. Belsky and several of his colleagues announced their findings last week at the international conference.
The investigation consists of 1 153 children and their families living in or near Boston. The youngsters, no more than 1 month old when they entered the study in 1991, will be tracked until the age of 7. Experimenters administered questionnaires to mothers in their homes and videotaped baby caretakers interacting with the kids at ages 1, 6, and 15 months. Independent observers rated the quality of each child care efforts and noted infant nervousness. Unlike most previous studies, this one allows researchers to observe each caretaker’s personality at child nursing, and kids’ emotional reaction by the equipment.
After taking family factors into account, other psychologists state that the researchers found no relation between the quality of child care and infants’ response. But the experimenters contend that the boys who spent more than 30 hours per week in child care exhibited more emotion for their mothers than other boys who didn’t, and the girls who spent the same hours per week in child care showed a modest rise in this emotion. Therefore, quality of child care outside home plays an important role in the connection between mothers and infants.
Jay Belsky implies that the study of child care ______.

A.
was never carried out in the past
B.
was not much done in detail in the past
C.
was greatly ignored by psychologists and researchers
D.
was interesting, but very difficult to make discovery

【单选题】4() A. at B. in C. on D. by

A.
There is probably no sound in (1) more chilling than the " hiss " of a diamondback rattlesnake. There is good reason: the western diamondback has killed more humans than (2) snake. It is easily excitable, very aggressive, frequently hungry, and deadly poisonous. Yet it doesn’t really hiss. Rather, it (3) its tail. A mature rattler can move its tail up and down between fifty and a hundred times a second! The hollow rattles (4) the tail, beating against each other, create the "hissing" sound.
B.
Why does this creature (5) rattles Rattlesnakes molt three times a year, shedding their outer layer of skin each time. But the molting skin near the tail is not discarded. (6) it hardens and hollows out, becoming another rattle. If a snake had never lost any rattles, you could (7) its age by counting them and dividing by three.
C.
Do the snakes need their rattles The rattles cannot be used in a mating call, (8) rattlesnakes are deaf. They are not a sign of hunger, for snakes with full stomachs rattle as often as hungry (9) . And in the wild, the rattling scares prey. It does not (10) them. Therefore, scientists believe that snakes use rattles merely to warn larger animals not to step on (11) . They have studied them extensively and found that it was a function more important in ages past when the rattlers shared the plains (12) 60 million buffalo!
D.
Rattlesnakes are one of the (13) advanced forms of " pit " vipers—animals who possess an organ for an extra sense. The pit organ is like an infrared radar sensor. (14) in the snake’s head, the pit organ can sense differences in temperature between inside and outside itself—differences as small as 1% of a degree. Not only can rattlesnakes (15) sense the presence of another animal—or a human—but they apparently can (16) determine its direction and range. These animals don’t feed on (17) , of course.

【单选题】According to researchers, people’s gestures are(). A.incidental B.comprehensible C.isolated D.precise

A.
All of us communicate with one another verbally (口头的) as well as non-verbally. Most of the time we are not aware that we’re doing it. We wave a hand, meet someone else’s eyes or look away, shift positions in a chair. We make these movements unconsciously. But researchers have discovered that there is a system to them almost as consistent (一致的) and comprehensible as language.
B.
Every culture has its body language. The way an Englishman crosses his legs is nothing like the way a male American does it. In talking, Americans are likely to end a statement with a lowering of the eyelids. They conclude a question with a lift of the hand or a widening of the eyes. With a future-tense verb they often gesture with a forward movement. There are regional idioms too. Your sex, ethnic background, social class and personal style all influence your body language. Nevertheless, you move and gesture within a certain idiom.
C.
Usually, the wordless communication acts to qualify the words. What the non-verbal elements express very often, and very efficiently, is the emotional side of the message. When a person feels liked or disliked, often it’s a case of "not what he said but the way he said it."
D.
Experts in the study of communication through body movement are not prepared to spell out a precise vocabulary of gestures. When an American rubs his nose, it may mean he is disagreeing with someone or rejecting something. But there are other possible interpretations, too. The expert looks for patterns in the context, not for an isolated meaningful gesture.
