In this search for energy the fungus has become the earth' s major source of rot and decay. Wherever you see mold forming on a piece of bread, or a pile of leaves turning to compost, or a blown-down tree becoming pulp on the ground, you are watching a fungus eating. Without fungus action the earth would be piled high with the dead plant life of past centuries. In fact, certain plants which contain resins that are toxic to fungi will last indefinitely. Specimens of the redwood, for instance, can still be found resting on the forest floor centuries after having been blown down.
The title below that best expresses the main idea of this passage is ______.
A.Life without Chlorophyl
B.The Source of Rot and Decay
C.The Harmul Qualities of Fungi
D.The Strange World of the Fungus

第10题
But now where was a spot of earth to be found in all that white monotony? They had talked of death at the house. I hoped that my little sister would live, but I was afraid of nature.
I reached a little spring. I looked down to its bottom, wondering whether I should leave my offering there, or keep on in search of a spot of earth. If I put my offering in the water, would it reach the bottom and touch the earth, or would it float away, as it had always done when I made my offering to the water spirit?
Once more I started on in my search of the bare ground.
The surface was crusted in some places, and walking was easy; in other places I would wade through a foot or more of snow. Often I paused, thinking to clear the snow away in some place and there lay my offering. But no, my faith must be in nature, and I must trust to it to lay bare the earth. It was a hard struggle for so small a child.
I went on and on; the reeds were waving in the wind. I stopped and looked at them. A reed, whirling in the wind, had formed a space round its stem, making a loose socket. I stood looking into the opening. The reed must be rooted in the ground, and the hole must follow the stem to the earth. If I poured my offerings into the hole, surely they must reach the ground; so I said the prayer that l had been taught, and dropped my tobacco and red feathers into the opening that nature itself had created.
No sooner was the sacrifice accomplished than a feeling of doubt and fear thrilled me. What if my offering should never reach the earth? Would my little sister die?
Not till I turned homeward did I realize how cold I was. When at last I reached the house they took me in and warmed me, but did not question me, and I said nothing. Everyone was sad, for the little one had grown worse.
The next day the medicine-woman said my little sister was beyond hope; she could not live. Then bitter remorse was mine, for I thought I had been unfaithful, and therefore my little sister was to be called to the spirit land. I was a silent child, and did not utter my feelings; my remorse was intense.
The phrase "white monotony" (Paragraph 2) refers to the fact that
A.white people find farm life dull.
B.snow covers the landscape.
C.the narrator is blind.
D.nothing special happens in the story.
