In finance, an option is a contract between a buyer and a seller that gives the buyer of the option the right, but not the obligation, to buy or to sell a specified asset (underlying) on or before the option's expiration time, at an agreed price, the strike price.

In return for granting the option, the seller collects a payment (the premium) from the buyer. Granting the option is also referred to as "selling" or "writing" the option.

A call option gives the buyer of the option the right but not the obligation to buy the underlying at the strike price.
A put option gives the buyer of the option the right but not the obligation to sell the underlying at the strike price.
If the buyer chooses to exercise this right, the seller is obliged to sell or buy the asset at the agreed price.[1][2] The buyer may choose not to exercise the right and let it expire. The underlying asset can be a piece of property, a security (stock or bond), or a derivative instrument, such as a futures contract.

The theoretical value of an option is evaluated according to several models. These models, which are developed by quantitative analysts, attempt to predict how the value of an option changes in response to changing conditions. Hence, the risks associated with granting, owning, or trading options may be quantified and managed with a greater degree of precision, perhaps, than with some other investments. Exchange-traded options form an important class of options which have standardized contract features and trade on public exchanges, facilitating trading among independent parties. Over-the-counter options are traded between private parties, often well-capitalized institutions that have negotiated separate trading and clearing arrangements with each other.

Another important class of options, particularly in the U.S., are employee stock options, which are awarded by a company to their employees as a form of incentive compensation. Other types of options exist in many financial contracts, for example real estate options are often used to assemble large parcels of land, and prepayment options are usually included in mortgage loans. However, many of the valuation and risk management principles apply across all financial options.

[edit] Contract specifications
Every financial option is a contract between the two counterparties with the terms of the option specified in a term sheet. Option contracts may be quite complicated; however, at minimum, they usually contain the following specifications:[3]

whether the option holder has the right to buy (a call option) or the right to sell (a put option)
the quantity and class of the underlying asset(s) (e.g. 100 shares of XYZ Co. B stock)
the strike price, also known as the exercise price, which is the price at which the underlying transaction will occur upon exercise
the expiration date, or expiry, which is the last date the option can be exercised
the settlement terms, for instance whether the writer must deliver the actual asset on exercise, or may simply tender the equivalent cash amount
the terms by which the option is quoted in the market to convert the quoted price into the actual premium-–the total amount paid by the holder to the writer of the option.

④ 2017年将基因工程应用于人类，这节奏是不是快了点

尽管CRISPR基因编辑技术有着广阔的医学应用前景，但是由于安全性和医学伦理等方面的原因，目前这项技术饱受争议。然而，美国基因编辑公司Editas Medicine近日宣布，希望于2017年将CRISPR基因编辑技术应用于一种罕见的遗传性眼疾的治疗。要知道，目前CRISPR基因编辑技术还仅在动物和不能存活的人类胚胎细胞上试验过，这节奏是不是快了点？
上周在由《麻省理工学院科技评论》举办的EmTech会议上， Editas Medicine公司CEO Katrine Bosley表示，该公司计划在2017年开启CRISPR治疗雷伯式先天黑内障的临床试验。CRISPR-Cas9是一种强大的基因编辑工具，使得科学家能够将缺陷基因替换为健康基因。如果Editas该计划顺利实施的话，那么将会是CRISPR技术在人类基因编辑上的首次临床应用。
许多遗传疾病，如亨廷顿氏舞蹈病和囊肿性纤维化都是由基因缺陷或基因突变所引起的，其中大部分传统疗法无法治愈。通过基因筛查，也就是通过检测分析父母双方的基因组，可以得知将来后代罹患某些遗传疾病的风险，从而作出优生优育的理性抉择。不过基因筛查在预防儿童罹患遗传疾病上并非完全有效，而且目前除了利用基因筛查对遗传疾病采取预防措施外，这些疾病尚无有效的治疗手段。因此，Editas作为一家基于CRISPR基因编辑技术的初创公司，同Intellia Therapeutics和CRISPR Therapeutics公司一样，希望利用CRISPR基因编辑技术研发出一些遗传疾病的新型治疗手段。Katrine Bosley表示，由于CRISPR可以修正缺陷基因，有望用其来治疗由基因缺陷造成的大量遗传疾病。
据报道，Editas公司计划用CRISPR基因编辑技术来治疗一种罕见的眼疾：雷伯氏先天性黑内障。该疾病对眼睛的视网膜产生破坏性影响，患者天生只能看到大且明亮的物体。患上雷伯氏先天性黑内障的后果非常严重，患儿的视力低下到与失明无差异。
遗传疾病数量非常多，那么，Editas公司为什么选择雷伯氏先天性黑内障作为主攻目标呢？其一是基因编辑的标靶好定位。理论上，通过将携带CRISPR-Cas9的改良病毒直接注射进病人的视网膜并清除导致疾病的“元凶”CEP290基因，就能治愈该疾病。其二是治疗效果好检验。由于该病和视力密切相关，可以很容易地检验治疗成功与否。Katrine Bosley表示，“选择雷伯氏先天性黑内障的部分原因是CRISPR容易解决该疾病的致病缺陷，导致该疾病的基因缺陷已经确定。” Katrine Bosley也坦承，目前的治疗方案是会能起效以及否会产生副作用尚不能确定。Bosley表示在进行人类试验之前，仍需要在动物身上进行大量的测试。
Editas medicine公司位于美国马萨诸塞州剑桥市，成立于2013年11月，创始人包括Feng Zhang，Jennifer Doudna等，而这两人也是CRISPR技术的最初研发人员。今年8月该公司获得1.2亿美元的B轮融资，由Boris Nikolic领投，比尔•盖茨、Google Ventures等跟投，以资助其利用基因编辑技术对雷伯氏先天性黑内障等遗传疾病展开治疗试验。

⑤ 呼啸山庄主要内容英文版

19世纪，在英国约克郡一个阴沉的荒原边上，一个名叫希斯克利夫的吉普赛男孩，被迪恩先生带到咆哮山庄。

In the 19th century, on the edge of a gloomy wilderness in Yorkshire, England, a gypsy boy named Heathcliff was taken to Roaring Heights by Mr. Dean.

他得到主人之女凯西的钟爱，凯西在爱的同时，又无法拒绝自己想过优裕生活的愿望，而能提供这种生活条件的是邻居艾德加·林顿。希斯克利夫得知后，悄然离去，凯西嫁给了林顿。

He was loved by his master's daughter, Casey. While she was in love, she couldn't refuse her desire to live a prosperous life. Heathcliff learns, quietly leaves, Kathy married Linton.

希斯克利夫回来了。林顿的妹妹伊贝拉爱上了他，他买下了咆哮山庄。他与伊莎贝拉结婚以后，希斯克利夫的冷淡无情使伊莎贝拉很快枯萎掉谢，凯西也因为悲伤过度而濒临死亡。

Heathcliff is back. Linton's sister, Ibera, fell in love with him and bought Roaring. After marriage to Isabella, Heathcliff's indince witheed Isabella, Kathy was on the verge of death because of her excessive grief.

希斯克利夫在凯西弥留之际来到她身边，把她抱到窗前姚望那方岩石——童年时代那曾是他们的“城堡”凯西说她等待着，总有一天他们会团圆，然后死去。

Heathcliff came Kathy her deathbed took her to Yao's window look rock. Kathy, who had been their "castle" her childhood, said she waited, and one day they would be reunited and die.

希斯克利夫心神错乱，在哀悼凯、期待死亡中捱过了20年。他对周围一切人都极端轻蔑、百般折磨，直到凯西的幽灵在一个严冬的雪夜把他召唤到他们最喜爱的荒原上某个地方，在死亡中重新聚会……

Heathcliff was distracted and spent 20 years Kay ecting death. He despised tormented everyone around him Casey's ghost somewhere on winter snowy to their favorite wilderness and reunited in death...

写作背景：

艾米丽生性寂寞，自小内向的她，缄默又总带着几分以男性自居的感觉，在她写作《呼啸山庄》时，这种困惑与不安的情绪变得更加急躁。

她迫切需要创造一个虚构的世界来演绎它，把自己心底几近撕裂的痛苦借小说人物之口淋漓尽致地发泄出来。因此《呼啸山庄》是饱含作者心血与情感的作品。

⑦ 12306订票怎么选择上下铺

12306订票铺位是系统随机发放的，无法人为设定选择上下铺。如果因特殊原因和喜好限定某一铺位，可以带上乘车人和买票人的身份证到就近的车站售票厅或车票代售点购买。如果票充裕，都会买到想要的铺位。

网上购票，系统随机刷出来的座位和铺位都不一定是想要的。拿硬卧来说，系统对于卧铺是平均分配的。买一张基本上是上铺；买两张一般是上、中各一张或上、下各一张；买三张的时候上、中、下各一张。
