单选题 Both plants and animals of many sorts show remarkable changes in form, structure, growth habits, and even mode of reproduction in becoming adapted to different climatic environment, types of food supply, or mode of living. This divergence in response to evolution is commonly expressed by altering the form and function of some part or parts of the organism, the original identity of which is clearly discernible. For example, the creeping foot of the snail is seen in related marine preemptors to be modified into a flapping organ useful for swimming, and is changed into prehensile arms that bear sartorial disks in the squids and other cephalopods. The limbs of various mammals are modified according to several different modes of life—for swift running (cursorial) as in the horse and antelope, for swinging to several different modes of life—for swinging in trees (arboreal) as in the monkey, for digging ( fossorial ) as in the moles and gophers, for flying (volant) as in the bats, for swimming (aquatic) as in the seals, whales and dolphins, and for other adaptations. The structures or organs that show main change in connection with this adaptive divergence are commonly identified readily as homologous, in spite of great alterations. Thus, the fingers and wrist bones of a bat and whale, for instance, have virtually nothing in common except that they are definitely equivalent elements of the mammalian limb.

单选题 In the summer of 999, Leif Erikson voyaged to Norway and spent the following winter with King Olaf Tryggvason. Substantially the same account is given by both the Saga of Eric the Red and the Flat Island Book. The latter says nothing about Leif's return voyage to Greenland, but according to the former it was during this return voyage that Leif discovered America. The Flat Island Book, however, tells of another and earlier landfall by Biarni, the son of a prominent man named Heriulf, and makes that the inspiration for the voyage to the new land by Leif. In brief, like Leif, Biarni and his companion sight three countries in succession before reaching Greenland, and to come upon each new land takes 1 "doegr" more than the last until Biarni comes to land directly in front of his father's house in the lastmentioned country. This narrative has been rejected by most later writers, and they may be justified. Possibly, Biarni was a companion of Leif when he voyaged from Norway to Greenland via America, or it may be that the entire tale is but a garbled account of that voyage and Biarni another name for Leif. It should be noted, however, that the stories of Leif's visit to King Olaf and Biarni's to that king's predecessor are in the same narrative in the Flat Island Book, so there is less likelihood of duplication than if they were from different sources. Also, Biarni landed on none of the lands he passed, but Leif apparently landed on one, for he brought back specimens of wheat, vines, and timber. Nor is there any good reason to believe that the first land visited by Biarni was Wineland. The first land was "level and covered with woods", and "there were small hillocks upon it". Of forests, later writers do not emphasize them particularly in connection with Wineland, though they are often noted incidentally. And of hills, the Saga says of Wineland only that "wherever there was hilly ground, there were vines". Additionally, if the two narratives were taken from the same source we should expect a closer resemblance of Helluland. The Saga says of it. "They found there hellus (large flat stones)." According to the Biarni narrative, however, "this land was high and mountainous." The intervals of 1, 2, 3, and 4 "doegr" in both narratives are suggestive, but mythic formulas of this kind may be introduced into narratives without altogether destroying their historicity. It is also held against the Biarni narrative that its hero is made to come upon the coast of Greenland exactly in front of his father's home. But it should be recalled that Heriufsness lay below two high mountains which served as landmarks for navigators. I would give up Biarni more readily were it not that the story of Leif's voyage contained in the supposedly more reliable Saga is almost as amazing. But Leif's voyage across the entire width of the North Atlantic is said to be "probable" because it is incorporated into the narrative of a preferred authority, while Biarni's is "improbable" or even "impossible" because the document containing it has been condemned.

单选题The man who invented Coca-Cola was not a native Atlantan, but on the day of his funeral every drugstore in town testimonially shut up shop. He was John Styth Pemberton, born in 1833 in Knoxville, Georgia, eighty miles away. Sometimes known as Doctor, Pemberton was a pharmacist who, during the Civil War, led a cavalry troop under General Joe Wheeler. He settled in Atlanta in 1869, and soon began brewing such patent medicines as Triplex Liver Pills and Globe of Flower Cough Syrup. In 1885, he registered a trademark for something called French Wine Coca—Ideal Nerve and Tonic Stimulant; a few months later he formed the Pemherton Chemical Company, and recruited the services of a bookkeeper named Frank M. Robinson, who not only had a good head for figures but, attached to it, so exceptional a nose that he could audit the composition of a batch of syrup merely by sniffling it. In 1886, a year in which, as contemporary Coca-Cola officials like to point out, Conan Doyle unveiled Sherlock Holmes and France unveiled the Statue of Liberty-Pemberton unveiled a syrup that he called Coca-Cola. It was a modification of his French Wine Coca. He had taken out the wine and added a pinch of caffeine, and, when the end product tasted awful, had thrown in some extract of cola nut and a few other oils, blending the mixture in a three-legged iron pot in his back yard and swishing it around with an oar. He distributed it to soda fountains in used beer bottles, and Robinson, with his flowing bookkeeper's script, presently devised a label, on which "Coca-Cola" was written in the fashion that is still employed. Pemberton looked upon his mixture less as a refreshment than as a headache cure, especially for people whose headache could be traced to over-indulgence. On a morning late in 1886, one such victim of the night before dragged himself into an Atlanta drugstore and asked for a dollop of Coca-Cola. Druggists customarily stirred a teaspoonful of syrup into a glass of water, but in this instance the man on duty was too lazy to walk to the fresh-water tap, a couple of feet off. Instead, he mixed the syrup with some soda water, which was closer at hand. The suffering customer perked up almost at once, and word quickly spread that the best Coca-Cola was a fizzy one.
