单选题Centuries ago, man found out that removing moisture from food helps to preserve it, and that the easiest way to do this is to expose the food to sun and wind. All foods contain water—cabbage and other leaf vegetables contain as much as 92% water, potatoes and other root vegetables 80%, lean meat 70% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌) which cause food to go bad is checked. At present most foods are dried mechanically. The conventional method of such dehydration (脱水) is to put food in chambers through which hot air is blown at temperature of about 110℃ at entry to about 43℃ at exit. This is the usual method for drying such things as vegetables, minced meat and fish. Liquids such as milk, coffee, tea, soup and egg may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is stripped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed. Dried foods take up less room and weight less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space, they are also popular with housewives for it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.

单选题{{B}}Text 3{{/B}} There is one difference between the sexes on which virtually every expert and study agree: Men are more aggressive than women. It shows up in two-year-olds. It continues through school days and persists into adulthood. It is even constant across cultures. And there is little doubt that it is rooted in biology--in the male sex hormone testosterone. If there's a feminine trait that's the counterpart of male aggressiveness, it's what social scientists awkwardly refer to as "nurturance". Feminists have argued that the nurturing nature of women is not biological in origin, but rather has been drummed into women by a society that wanted to keep them in the home. But the signs that it is at least partly inborn are too numerous to ignore. Just as tiny infant girls respond more readily to human faces, female toddlers learn much faster than males how to pick up nonverbal cues from others. And grown women are far more adept than men at interpreting facial expressions: A recent study by University of Pennsylvania brain researcher Ruben Gurr showed that they easily read emotions such as anger, sadness and fear. The only such emotion men could pick up was disgust. What difference do such differences make in the real world? Among other things, women appear to be somewhat less competitive--or at least competitive in different ways--than men. At the Harvard Law School, for instance, female students enter with credentials just as outstanding as those of their male peers. But they don't qualify for the prestigious Law Review in proportionate numbers, a fact some school officials attribute to women's discomfort in the incredibly competitive atmosphere. Students of management styles have found fewer differences than they expected between men and women who reach leadership positions, perhaps because many successful women deliberately imitate masculine ways. But an analysis by Purdue social psychologist Alice Eagly of 166 studies of leadership style did find one consistent difference: Men tend to be more "autocratic"--making decisions on their own--while women tend to consult colleagues and subordinates more often. Studies of behavior in small groups turn up oven more differences. Men will typically dominate the discussion, says University of Toronto psychologist Kenneth Dion, spending more time talking and less time listening.

单选题It is well known that when an individual joins a group he tends to accept the group's standards of behavior and thinking. He is expected to behave in accordance with these norms—in other words the group expects him to conform. Many illustrations could be given of this from everyday life, but what is of particular interest to psychologists is the extent to which people's judgments and opinions can be changed as a result of group pressure. In a typical experiment, the experimenter asks for volunteers to join a group which is investigating visual perception. The victims are not, therefore, aware of the real purpose of the experiment. Each volunteer is taken to a room where he finds a group of about seven people who are collaborating with the experimenter. The group is shown a standard card which contains a single line. They are then asked to look at a second card. This has three lines on it. One is obviously longer than the line on the first card, one is shorter and one the same length. They have to say which line on the second card is the same length as the line on the standard card. The other members of the group answer first but what the volunteer does not know is that they have been told to pick one of the wrong lines. The volunteer sees that the other members of the group unanimously choose a line which is obviously not the same length as the one on the standard card. When it is his turn to answer he is faced with the unanimous opinion of the rest of the group—all the others have chosen line A but he quite clearly sees line B as correct. What will he do? According to Asch, more than half of the victims chosen will change their opinion. What is equally surprising is that, when interviewed about their answers, most explained that they knew the group choice was incorrect but that they yielded to the pressure of the group because they thought they must be suffering from an optical illusion.
