Last week when I took a walk down the road at my relatives I was surprised to see many ear
thworms on the asphalt road. I had walked on this road many times before and never seen the earthworms. Then I recognized that I had never walked just after a heavy rain. So, I suppose that the rain caused the earthworms to come out of the ground. Identify the pattern of reasoning (x is the difference; x is the common thread)

请判断并选择下面这段文字的写作逻辑： We highlight the need to integrate belowground organisms into biodiversity research, despite differences in the scale of sampling, if we are to fully understand large-scale patterns of biodiversity and their underlying drivers, especially if processes underlying macroecological patterns differ between aboveground and belowground diversity. The inclusion of soil taxa may alter the distribution of biodiversity hotspots and conservation priorities. For example, protected areas may not be protecting earthworms, despite their importance as ecosystem function providers and soil ecosystem engineers for other organisms. By modeling both realms, aboveground/belowground comparisons are possible, potentially allowing a clearer view of the biodiversity distribution of whole ecosystems.
A、Specific to General
B、Problem to Solution
C、Process
D、Old to New

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
If you see a fish tail splash in a shallow stream, you'll know that a trout is feeding on underwater insects that cling to the rocky bottom. A V-shaped wave through the water could be a large fish chasing a smaller one. And a loud jump in a splashy circle may be a big hungry fish gobbling up a frog or a swimming mouse.
It's always a good idea to watch the water for a while before you begin fishing. If you can figure out what the fish are feeding on, offer it to them on your hook, and you'll catch more fish.
All you need for bait fishing is a line on a pole, a couple of hooks, and some split-shot sinkers. Most of you who fish use earthworms as bait, but in their natural diet, fish eat very few worms.
The next time you are fishing in a clear stream, turn over some rocks and you will find insects clinging to the undersides. These insects, called nymphs, are good fish bait. Put a nymph on a very small hook and squeeze a split-shot sinker on your line a foot above it. The weight will drift the bait along the bottom of the stream, where the fish normally look for nymphs.
While you are collecting nymphs, you might also find some caddis cases. These rectangular cases made of tiny pebbles or sticks, are constructed by caddis larvae. Safe in their cases, the larvae cling to the stream's rocky bottom but sometimes they lose their hold and are carded downstream by the current, and hungry trout gobble them up -- case and all. You can use a caddis case as bait, drifting it along the bottom as you would a nymph.
Fish also eat caterpillars, grasshoppers, and beetles that fall into or swim on the water. And some fish will eat anything they can fit into their mouths.
Whatever bait you choose, remember to make it appear natural to the fish. If your sandwich leaped off the plate and danced across the table, you would hesitate to eat it. The same is true of fish. They are very cautious of any food that doesn't look and act natural.
Always use a hook smaller than your bait, so the fish won't see it. If you want the bait to sink, squeeze a split-shot onto the line. If you want it to float, take off the sinker. Watch the water and see how different insects behave; they imitate them with your bait.
The passage is mainly about ______.
A．how to eat fish
B．how to catch insects
C．how to fish
D．fish in the stream

My mother's relations were very different from the Mitfords. Her brother, Uncle Geoff, who
often came to stay at Swinbrook, was a small, spare man with thoughtful blue eyes and a rather silent manner. Compared to Uncle Tommy, he was an intellectual of the highest order, and indeed his satirical pen belied his mild demeanor. He spent most of his waking hours composing letters to The Times and other publications in which he outlined his own particular theory of the development of English history. In Uncle Geoff's view, the greatness of England had risen and waned over the centuries in direct proportion to the use of natural manure in fertilizing the soil. The Black Death of 1348 was caused by gradual loss of the humus fertility found under forest trees. The rise of the Elizabethans two centuries later was attributable to the widespread use of sheep manure.

Many of Uncle Geoff's letters-to-the-editor have fortunately been preserved in a privately printed volume called Writings of a Rebel. Of the collection, one letter best sums up his views on the relationship between manure and freedom. He wrote:
Collating old records shows that our greatness rises and falls with the living fertility of our soil. And now, many years of exhausted and chemically murdered soil, and of devitalized food from it, has softened our bodies and still worse, softened our national character. It is an actual fact that character is largely a product of the soil. Many years of murdered food from deadened soil has made us too tame. Chemicals have had their poisonous day. It is now the worm's turn to reform. the manhood of England. The only way to regain our punch, our character, our lost virtues, and with them the freedom natural to islanders, is to compost our land so as to allow moulds, bacteria and earthworms to remake living soil to nourish Englishmen 's bodies and spirits.
The law requiring pasteurization of milk in England was a particular target of Uncle Geoff's. Fond of alliteration, he dubbed it "Murdered Milk Measure", and established the Liberty Restoration League, with headquarters at his house in London, for the specific purpose of organizing a counteroffensive. "Freedom not Doctordom" was the League's proud slogan. A subsidiary, but nevertheless important, activity of the League was advocacy of a return to the "unsplit, slowly smoked fish" and bread made with "English stone-ground flour, yeast, milk, sea salt and raw cane-sugar."
According to Uncle Geoff, national strength could only be regained by
A．reforming the manhood of England.
B．using natural manure as fertilizer.
C．eating more bacteria-free food.
D．granting more freedom to Englishmen.
