1.   In some cases we might easily put down to disuse modifications of structure which are wholly, or mainly, due to natural selection. Mr. Wollaston has discovered the remarkable fact that 200 beetles, out of the 550 species inhabiting Madeira, are so far deficient in wings that they cannot fly; and that of the twenty-nine endemic genera, no less than twenty-three genera have all their species in this condition! Several facts, namely, that beetles in many parts of the world are very frequently blown to sea and perish; that the beetles in Madeira, as observed by Mr Wollaston, lie much concealed, until the wind lulls and the sun shines; that the proportion of wingless beetles is larger on the exposed Dezertas than in Madeira itself; and especially the extraordinary fact, so strongly insisted on by Mr. Wollaston, of the almost entire absence of certain large groups of beetles, elsewhere excessively numerous, and which groups have habits of life almost necessitating frequent flight; these several considerations have made me believe that the wingless condition of so many Madeira beetles is mainly due to the action of natural selection, but combined probably with disuse. For during thousands of successive generations each individual beetle which flew least, either from its wings having been ever so little less perfectly developed or from indolent habit, will have had the best chance of surviving from not being blown out to sea; and, on the other hand, those beetles which most readily took to flight will oftenest have been blown to sea and thus have been destroyed.The insects in Madeira which are not ground-feeders, and which, as the flower-feeding coleoptera and lepidoptera, must habitually use their wings to gain their subsistence, have, as Mr. Wollaston suspects, their wings not at all reduced, but even enlarged. This is quite compatible with the action of natural selection. For when a new insect first arrived on the island, the tendency of natural selection to enlarge or to reduce the wings, would depend on whether a greater number of individuals were saved by successfully battling with the winds, or by giving up the attempt and rarely or never flying. As with mariners ship-wrecked near a coast, it would have been better for the good swimmers if they had been able to swim still further, whereas it would have been better for the bad swimmers if they had not been able to swim at all and had stuck to the wreck.

2. 西汉王朝是在秦末农民大起义的风暴中建立起来的。初建伊始,庶民出身的汉高祖刘邦对如何治理国家、巩固政权,并没有充分的心理和理论上的准备,因此摆在他面前的重要问题之一,就是尽快总结秦王朝乃至古往今来治乱兴亡的历史经验教训,以利自己的长治久安。于是,他曾对陆贾提出:试为我著秦所以失天下,吾所以得之者,及古成败之国。故而陆贾乃粗述存亡之征,凡十二篇。每奏一篇,高帝未尝不称善,左右呼万岁。号其书曰《新语》(《史记?陆贾列传》)。从此在西汉散文中,首先掀起了以切用为本,总结历史经验教训的政论文著作热潮。

5.   This wine-shop keeper was a bull-necked', martial-looking man of thirty, and he should have bean of a hot temperament, for, although it was a bitter day, he wore no coat, but carried one slung over his shoulder. His shirt-sleeves were rolled up, too, and his brown arms were bare to the elbows. Neither did he wear anything more on his head than his own crisply-curling short dark hair. He was a dark man altogether, with good eyes and a good bold breadth between them. Good-humoured looking on the whole, but implacable-looking, too; evidently a man of a strong resolution and a set purpose; a man not desirable to be met, rushing down a narrow pass with a gulf on either side, for nothing would turn the man.

2. There was a very large and beautiful tree in the glade we had just entered, with thick wide-spreading branches that sloped out in lapping fans like a beech or pine. It was trimmed underneath some twenty feet up, and stood there like a huge umbrella, with circling seats beneath.
3.   On this second day, Mr. Lorry saluted him cheerfully by his name, and spoke to him on topics that had been of late familiar to them. He returned no reply, but it was evident that he heard what was said, and that he thought about it, however confusedly. This encouraged Mr. Lorry to have Miss Pross in with her work, several times during the day; at those times, they quietly spoke of Lucie, and of her father then present, precisely in the usual manner, and as if there were nothing amiss. This was done without any demonstrative accompaniment, not long enough, or often enough to harass him; and it lightened Mr. Lorry's friendly heart to believe that he looked up oftener, and that he appeared to be stirred by some perception of inconsistencies surrounding him.

      My seat, to which Bessie and the bitter Miss Abbot had left meriveted, was a low ottoman near the marble chimney-piece; the bed rosebefore me; to my right hand there was the high, dark wardrobe, withsubdued, broken reflections varying the gloss of its panels; to myleft were the muffled windows; a great looking-glass between themrepeated the vacant majesty of the bed and room. I was not quitesure whether they had locked the door; and when I dared move, I got upand went to see. Alas! yes: no jail was ever more secure. Returning, Ihad to cross before the looking-glass; my fascinated glanceinvoluntarily explored the depth it revealed. All looked colder anddarker in that visionary hollow than in reality: and the strangelittle figure there gazing at me, with a white face and armsspecking the gloom, and glittering eyes of fear moving where allelse was still, had the effect of a real spirit: I thought it like oneof the tiny phantoms, half fairy, half imp, Bessie's evening storiesrepresented as coming out of lone, ferny dells in moors, and appearingbefore the eyes of belated travellers. I returned to my stool.
