[填空题]Do women talk more than men Do men talk in the same way as women According to the latest research from the United States of America, men and women talk such different languages that it is like people from two different cultures trying to communicate. Professor Deborah Tannen, of Georgetown University, has noticed differences in the style of boys’ and girls’ conversations from an early age. She says that little girls’ conversation is less definite than boys’ and expresses more doubts. Little boys use conversation to establish status with their listeners.
These differences continue into adult life, she says. In public conversations men talk most and interrupt other speakers more. In private conversations, men and women speak in equal amounts-although they say things in a different style. Professor Tannen believes that, fur women, private talking is a way to establish and test intimacy (亲密). For men, private talking is a way to explore the power structure of a relationship.

[单项选择]Mycorrhizal fungi infect more plants than do any other fungi and are necessary for many plants to thrive, but they have escaped widespread investigation until recently for two reasons. First, the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely infected. Second, the fungi cannot as yet be cultivated in the absence of a living root. Despite these difficulties, there has been important new Work that suggests that this symbiotic association can be harnessed to achieve more economical use of costly superphosphate fertilizer and to permit better exploitation of cheaper, less-soluble rock phosphate. Mycorrhizal benefits are not limited to improved phosphate uptake in host plants. In legumes, mycorrhizal inoculation has increased nitrogen fixation beyond levels achieved by adding phosphate fertilizer alone. Certain symbiotic associations also increase the host plant’s resistance to harmful root fungi. Whether this resistance results from
A. There are at least three hypotheses that might account for the increase.
B. The plants that Show increased resistance also exhibit improved nitrogen fixation.
C. Such increases may be independent of mycorrhizal infection.
D. It is unlikely that a satisfactory explanation can be found to account for the increas
