听力原文: (35)Research indicates that parents who reward self-control and independence tend to have children with high achievement motivation. (33) Such parents set high standards for their children but allow them to work at their own level and to make their own mistakes. That is to say, they are not very critical. By contrast, parents of low need achievers typically set impossibly high goals for their children and make extreme demands, In addition, parents of high need achievers encourage good performance but do not blame their children angrily when they fail. (34)If a child comes home from school with As and one B on a report card, the parents focus on the As, while not paying much attention to the B; parents of a potential low need achiever tend to ask, "Why the B?" Parents of high need achievers respond to middle grades with warmth and suggestions for reasonable goals and ways to reach them. They can help their children to find a way out. Parents of low need achievers would scold and punish the child. When a child is having trouble with a maths problem, the parents of high need achievers will suggest the general procedure and let the child work out the particular solution; a low need achiever's parent will solve the problem and then hand the child the answer.
Closely related to motivation are emotions, which can activate and direct behavior. in much the same way as physiological, social and psychological motivations do.

A.They usually leave their children alone.
B.They set high standards for their children.
C.They allow for failure on the part of their children.
D.They control their children to a minimum degree.
How does the developer of a large database system achieve(71)and data independence? How does the developer make certain that stored items are(72)and do not simply disappear in the immensities of the database, as if in quicksand?
One solution is to set up a(73)system, in which all data (the internal level), all records and files (the conceptual level), and all user interfaces (the external level) are controlled by one central programming group. This may seem the most useful solution. But worldwide enterprises such as the meteorological and satellite tracking networks, IBM, and General Motors gather and record information at a very large number of locations. To stay flexible and avoid top - heaviness, such an organization might want to avoid excessive centralization.
A centralized system is(74), but it may not be responsive to user needs. This is particularly true in a large organization - the worldwide meteorological network, for example, Data-gathering methods in the Himalayas, the equatorial jungles are different in very possible way. It is reasonable to believe that the best choices for the corresponding data storage and access structures ought to be just as different. A centralized database system would not(75)such differences.
A.consistency
B.identification
C.coherence
D.convergence
