元音字母，或母音字母，是指语言里起着发声作用的字母。元音又作“母音”，就是这个意思。在拉丁字母中，A、E、I、O、U通常都是元音字母。然而，具体的定义还是视乎各种语言的定义。例如，在威尔士语，W和Y也是元音字母；捷克语用上了R来表示其中一个卷舌的元音，所以在捷克语中，“R”也是一个元音字母。另外，在印度次大陆的不少语言，都有元音化r及元音化l这两个特殊元音。香港开埠初期，当地通行广州话，而广州话的“子”、“四”等字的元音（韵母），在外国人听起来，就好像英语的“Z”音，所以殖民地官员用上了Z来拼这些字，变成了“Tsz”、“Sz”。这么说来，连“Z”也可以变成元音字母了。国语的注音二式和雅礼拼音也都是如此。所以，要看一个字母是否元音字母，并不能死记，而要随同不同的语言而有变化。希腊字母的道理也相同，因为在特殊的程况下 “Η”可以不是元音字母，而是标示/h/音的字母。对于其他采用拼音文字的语言来讲则比较简单，因为它们都有特定的字母来表示元音。

的

shy的比较级，属于规则的边缘情况。“以-y结尾的词接-er时，y要变为i”这条规则，主要是为-y发[ɪ]音的情况设计的。shy这个词，表面上符合规则，但实际上并不符合规则的初衷，所以人们在实际使用中就会无所适从、左右摇摆。 shy造句 1、What situation makes youshy? 什么情况让你害羞。 2、Theshygirl was afraid to contradict. 害羞的女孩害怕矛盾。 3、Was heshyas a child? 他小时候害羞吗？ 4、She is tooshyto dare accost him. 她太害羞了，不敢跟他搭讪。 5、Mary was veryshybefore she met Jack; he brought her out a lot. 玛丽在遇到杰克之前很害羞，他把她带了很多出去。

ac由ad而来，字首 ad 源自拉丁文介系词 ad,在拉丁文中为 to 之意. ad 的拼法变化相当复杂,为了与字根配合,第二个字母d会消失或同化,而衍生出 a,ac,af,ag,al,an,ap,ar,as,at 各种形态,如 accustom v. [使习惯於],affix v. [黏上],append v. [添加] 等等. ad 原意虽表示方向,但与字根配合之后,则必须视该字的字根来定义.如 accelerate v. [促进],由字首 ac加上字根 celer [敏捷] 而成, 字根也是该字的意思. 再如adapt v. [使适应], 由ad 与 apt [适合的] 组成,apt 便成了该字的字义.accede 同意,应允accelerate 加快,加速accost 招呼,搭话account 叙述,说明accredit 将(..)归於accumulate 堆积,积聚accustom (使) 习惯於adhere 坚持,黏著adjourn 延期,休会adjure 恳求adjust 调节,使...适合administer 管理admire 钦佩,叹赏admonish 警告,告诫adopt 采纳,收养adore 敬慕,敬爱adorn 装饰adulterate 搀混,使品质低落affable 和蔼可亲,殷勤的affiliate 联合,加入,加盟affirm 断言affix 黏上,贴上,附加afflict 使...痛苦affront 侮辱aggrandize 增强势力aggravate 加重,惹怒aggregate 总计,合计aggrieve 使苦恼,使受屈align 使合作,排列成行allay 使和缓,使镇静alleviate 减轻,使缓和allocate 拨出allot 分配alloy 合金allure 引诱ally 联合,结合ameliorate 改善amenable 有责任,应服从的amend 修正,改良annex 并吞,附加annihilate 消灭annotate 评注,注解announce 正式宣布annul 取消,废止apparatus 仪器appeal 吸引力,恳求appease 使平静,缓和append 附加appertain 属於,与...有关apportion 分摊,分配appraise 鉴别,评价apprehend 逮捕,忧惧approbate 认可,赞成appropriate 拨(款),拨作(某目的)之用arouse 引起,激起arrange 处理,调解assail 攻击assault 攻击assemble 集合,聚集assent 同意,赞同assert 断言assimilate 同化,使类似,吸收associate 结交,联合assort 分类assortment 各色俱备之物,物品总集assuage 缓和assume 假定,假装assure 确告,保证attach 系,附加attain 得到attaint 污辱,羞辱attemper 冲淡,使缓和attend 出席,到,注意attest 证实attune 使合调,使一致aver 断言avow 公开承认,坦白承认awake 吵醒,唤起

　　杰克伦敦的《热爱生命》英文节选　　He closed his eyes and composed himself with infinite precaution.　　He steeled himself to keep above the suffocating languor that　　lapped like a rising tide through all the wells of his being. It　　was very like a sea, this deadly languor, that rose and rose and　　drowned his consciousness bit by bit. Sometimes he was all but　　submerged, swimming through oblivion with a faltering stroke; and　　again, by some strange alchemy of soul, he would find another shred　　of will and strike out more strongly.　　Without movement he lay on his back, and he could hear, slowly　　drawing near and nearer, the wheezing intake and output of the sick　　wolf"s breath. It drew closer, ever closer, through an infinitude　　of time, and he did not move. It was at his ear. The harsh dry　　tongue grated like sandpaper against his cheek. His hands shot out　　- or at least he willed them to shoot out. The fingers were curved　　like talons, but they closed on empty air. Swiftness and certitude　　require strength, and the man had not this strength.　　The patience of the wolf was terrible. The man"s patience was no　　less terrible. For half a day he lay motionless, fighting off　　unconsciousness and waiting for the thing that was to feed upon him　　and upon which he wished to feed. Sometimes the languid sea rose　　over him and he dreamed long dreams; but ever through it all,　　waking and dreaming, he waited for the wheezing breath and the　　harsh caress of the tongue.　　He did not hear the breath, and he slipped slowly from some dream　　to the feel of the tongue along his hand. He waited. The fangs　　pressed softly; the pressure increased; the wolf was exerting its　　last strength in an effort to sink teeth in the food for which it　　had waited so long. But the man had waited long, and the lacerated　　hand closed on the jaw. Slowly, while the wolf struggled feebly　　and the hand clutched feebly, the other hand crept across to a　　grip. Five minutes later the whole weight of the man"s body was on　　top of the wolf. The hands had not sufficient strength to choke　　the wolf, but the face of the man was pressed close to the throat　　of the wolf and the mouth of the man was full of hair. At the end　　of half an hour the man was aware of a warm trickle in his throat.　　It was not pleasant. It was like molten lead being forced into his　　stomach, and it was forced by his will alone. Later the man rolled　　over on his back and slept.　　There were some members of a scientific expedition on the whale-　　ship BEDFORD. From the deck they remarked a strange object on the　　shore. It was moving down the beach toward the water. They were　　unable to classify it, and, being scientific men, they climbed into　　the whale-boat alongside and went ashore to see. And they saw　　something that was alive but which could hardly be called a man.　　It was blind, unconscious. It squirmed along the ground like some　　monstrous worm. Most of its efforts were ineffectual, but it was　　persistent, and it writhed and twisted and went ahead perhaps a　　score of feet an hour.　　Three weeks afterward the man lay in a bunk on the whale-ship　　BEDFORD, and with tears streaming down his wasted cheeks told who　　he was and what he had undergone. He also babbled incoherently of　　his mother, of sunny Southern California, and a home among the　　orange groves and flowers.　　The days were not many after that when he sat at table with the　　scientific men and ship"s officers. He gloated over the spectacle　　of so much food, watching it anxiously as it went into the mouths　　of others. With the disappearance of each mouthful an expression　　of deep regret came into his eyes. He was quite sane, yet he hated　　those men at mealtime. He was haunted by a fear that the food　　would not last. He inquired of the cook, the cabin-boy, the　　captain, concerning the food stores. They reassured him countless　　times; but he could not believe them, and pried cunningly about the　　lazarette to see with his own eyes.　　It was noticed that the man was getting fat. He grew stouter with　　each day. The scientific men shook their heads and theorized.　　They limited the man at his meals, but still his girth increased　　and he swelled prodigiously under his shirt.　　The sailors grinned. They knew. And when the scientific men set a　　watch on the man, they knew too. They saw him slouch for"ard after　　breakfast, and, like a mendicant, with outstretched palm, accost a　　sailor. The sailor grinned and passed him a fragment of sea　　biscuit. He clutched it avariciously, looked at it as a miser　　looks at gold, and thrust it into his shirt bosom. Similar were　　the donations from other grinning sailors.　　The scientific men were discreet. They let him alone. But they　　privily examined his bunk. It was lined with hardtack; the　　mattress was stuffed with hardtack; every nook and cranny was　　filled with hardtack. Yet he was sane. He was taking precautions　　against another possible famine - that was all. He would recover　　from it, the scientific men said; and he did, ere the BEDFORD"S　　anchor rumbled down in San Francisco Bay.
