Radiocarbon Dating
Nowadays scientists can answer many questions about the past through a technique called radiocarbon(放射性碳), or carbon-14, dating. One key to understanding how and why something happened is to discover when it happened.
Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon-12, has six protons(质子) and six neutrons(中子) in its nucleus. Carbon-14, or C-14, is a radioactive, unstable form. of carbon that has two extra neutrons(原子核). It returns to a more stable form. of carbon through a process called decay(衰减). This process involves the loss of the extra neutrons and energy from the nucleus.
In Libby's radiocarbon dating technique, the weak radioactive emissions(放射) from this decay process are counted by instruments such as a radiation detector and counter. The decay rate is used to determine the proportion of C-14 atoms in the sample being dated.
Carbon-14 is produced in the Earth's atmosphere when nitrogen(氮)-14, or N-14, interacts with cosmic rays(宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C-14 formation is thought to occur at a constant rate. Now ratio of C-14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50,000 years.
All life on Earth is made of organic molecules(分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C-14 atoms to other carbon atoms in their tissues(组织). Once an organism(有机体) dies it stops taking in carbon in any form, and the C-14 already present begins to decay. Over time the amount of C-14 in the material decreases, and the ratio of C-14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C-14 atoms in a sample, the older that sample is.
Nowadays many scientists depend on radiocarbon for dating age-old objects.

Practice (or review) tens to build and maintain memory for a task or for any learned material. Over a period of no practice what has been learned tends to be forgotten and the adaptive consequences may not seem obvious. Yet, dramatic instances of sudden forgetting can be seen to be adaptive. In this sense, the ability to forget can be interpreted to have survived through a process of natural selection in animals. Indeed, when one's memory of an emotionally painful experience leads to serious anxiety, forgetting may produce relief. Nevertheless, an evolutionary painful experience leads to serious anxiety, forgetting may produce relief. Nevertheless, an evolutionary interpretation might make it difficult to understand how the commonly gradual process of forgetting survived natural selection.
In thinking about the evolution of memory together with all its possible aspects, it is helpful to consider what would happen if memories failed to fade. Forgetting clearly aids orientation in time, since old memories weaken and the new tend to stand out, providing clues for inferring duration. Without forgetting, adaptive ability would suffer. For example, learned behavior. that might have been correct a decade ago may no longer be. Cases are recorded of people who (by ordinary standards) forgot so little that their everyday activities were full of confusion. Thus forgetting seems to serve the survival of the individual and the species.
Another line of thought assumes a memory storage system of limited capacity that provides adaptive flexibility specifically through forgetting. In this view, continual adjustments are made between learning or memory storage (input) and forgetting (output). Indeed, there is evidence that the rate at which individuals forgets is directly related to how much they have learned. Such data offer gross support of contemporary models of memory that assume an input-output balance.
From the evolutionary point of view, ______.
A．the gradual process of forgetting is an indication of an individual's adaptability
B．if a person gets very forgetful of a sudden he must be very adaptive
C．forgetting for lack of practice tends to be obviously in adaptive
D．sudden forgetting may bring about adaptive consequences
Maslow examines in detail what these needs are. He points out not only that there are many needs ranging from basic physiological drives such as hunger to a more abstract desire for self-realization, but also that they are arranged in a hierarchy(等级制度 )whereby the lower-order needs must to a large degree be satisfied before the higher-order ones come into play.
One of the most obvious ways in which work organizations attract and retain members is through the realization, that economic factors are not the only inducement for working as indicated by Morse and Weiss. In line with the social respect and self-realization needs discussed by Maslow, factors such as association with others, self-respect gained through the work, and a high interest value of the work can serve effectively to induce people to work.
According to Maslow, a work organization is able to motivate people to work by______.
A．satisfying their physiological needs
B．satisfying their self-realization needs
C．satisfying hierarchy of their higher-order needs
D．first satisfying their lower-order needs
