单选题{{B}}Passage Two{{/B}} The vegetative forms of most bacteria are killed by drying in air, although the different species exhibit pronounced differences in their resistance. The tubercle bacillus is one of the more resistant, and vibrio cholera is one of the more sensitive to drying. In general, the encapsulated organisms are more resistant than the non-encapsulated forms. Spores are quite resistant to drying; the spores of the anthrax bacillus, for example, will germinate after remaining in a dry condition for ten years or more. The resistance of the pathogenic forms causing disease of the upper respiratory tract is of particular interest in connection with airborne infection, for the length of time that a droplet remains infective is a result, primarily, of the resistance of the particular microorganism to drying.

单选题______seeing the damage he had done, the child felt ashamed.

单选题More boys than girls are born all over the world, but a new study has found that the closer people live to the equator(赤道), the smaller the difference becomes. No one knows why. The imbalanced sex ratio at birth has been known for more than a hundred years, and researchers have found a large variety of social, economic and biological factors that relate to the sex ratio at birth-war, economic stress, age, diet, selective abortion and more. But latitude(纬度)is a natural phenomenon, unaffected by cultural or economic factors. To look at the effect of latitude, Kristen J. Navara of the University of Georgia used the latitude of the capital city in 202 countries, as well as 10 years of data on sex ratio at birth and annual variations in day length and temperature. Dr. Navara performed a statistical analysis which showed that there was a significant relation between sex ratios in favor of boys and latitude. African countries produced the lowest sex ratios—50. 7 percent boys—and European and Asian countries had the highest with 51. 4 percent. There are some possible explanations, but none entirely satisfactory. It could be that there is some survival value in producing more girls in warmer regions, but it is unclear what this might be. There may be genetic or racial differences that could explain it, but the connection persists over so many varied populations that this seems unlikely. Mice also produce more male offspring during shorter days or colder weather, but the reasons in these animals are just as mysterious as they are in humans. " There's a possibility that humans might be responding to factors they were programmed to respond to a long time ago-not cultural or socioeconomic, but climate and things like latitude," Dr. Navara said. " What's interesting is that we may be seeing something that connects us with our animal ancestry. "

完形填空 Culture shock might be called an occupational disease of people who have been suddenly transplanted abroad. Like most ailments, it has its own symptoms and cure. Culture shock is precipitated by the 51 that results from losing all our familiar signs and symbols of social intercourse. Those signs or cues include the thousand and one ways in which we 52 ourselves to the situation of daily life: when to shake hands and what to say, when we meet people, when and how to give tips, how to make purchases, when to accept and when to 53 invitations, when to take statements seriously and 54 . These cues, which may be words, gestures, facial expressions, customs, or norms, are acquired by all of us in the course of growing up and are 55 a part of our culture as the language we speak or the beliefs we accept. All of us depend 56 our peace of mind and our efficiency on hundreds of these cues, most of which we do not carry 57 conscious awareness. Now when an individual enters a strange culture, all or most of these familiar cues are 58 . He or she is like a fish out of water. No matter how broad-minded or full of goodwill you may be, a series of props have been knocked 59 you, followed by feeling of frustration and anxiety.

'The ways of the host county are bad because they make us feel bad' When foreigners in a strange land get together to grouse about the 60 country and its people, you can be sure they are suffering from culture shock.
