　　問法：

　　2.段落結構

　　3.段落目的

　　In general, diversity, by itself, does not ensure stability. Mathematical models of ecosystems likewise suggest that diversity does not guarantee ecosystem stability-just the opposite, in fact. A more complicated system is, in general, more likely than a simple system to break down. (A fifteen-speed racing bicycle is more likely to break down than a child's tricycle.)

　　In paragraph 5, why does the author provide the information that "(A fifteen-speed racing bicycle is more likely to break down than a child's tricycle)"?

　　A. To illustrate a general principle about the stability of systems by using an everyday example

　　B. To demonstrate that an understanding of stability in ecosystems can be applied to help understand stability in other situations

　　C. To make a comparison that supports the claim that, in general, stability increases with diversity

　　D. To provide an example that contradicts mathematical models of ecosystems

　　二、段落結構

　　Paragraph 6: Thus a proportion of the total volume of any sediment, loose or cemented, consists of empty space. Most crystalline rocks are much more solid; a common exception is basalt, a form of solidified volcanic lava, which is sometimes full of tiny bubbles that make it very porous.

　　Paragraph 7: The proportion of empty space in a rock is known as its porosity. But note that porosity is not the same as permeability, which measures the ease with which water can flow through a material; this depends on the sizes of the individual cavities and the crevices linking them.

　　11. What is the main purpose of paragraph 7?

　　A. To explain why water can flow through rock

　　B. To emphasize the large amount of empty space in all rock

　　C. To point out that a rock cannot be both porous and permeable

　　D. To distinguish between two related properties of rock
