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年將基因工程應用於人類，這節奏是不是快了點

盡管CRISPR基因編輯技術有著廣闊的醫學應用前景，但是由於安全性和醫學倫理等方面的原因，目前這項技術飽受爭議。然而，美國基因編輯公司Editas Medicine近日宣布，希望於2017年將CRISPR基因編輯技術應用於一種罕見的遺傳性眼疾的治療。要知道，目前CRISPR基因編輯技術還僅在動物和不能存活的人類胚胎細胞上試驗過，這節奏是不是快了點？
上周在由《麻省理工學院科技評論》舉辦的EmTech會議上， Editas Medicine公司CEO Katrine Bosley表示，該公司計劃在2017年開啟CRISPR治療雷伯式先天黑內障的臨床試驗。CRISPR-Cas9是一種強大的基因編輯工具，使得科學家能夠將缺陷基因替換為健康基因。如果Editas該計劃順利實施的話，那麼將會是CRISPR技術在人類基因編輯上的首次臨床應用。
許多遺傳疾病，如亨廷頓氏舞蹈病和囊腫性纖維化都是由基因缺陷或基因突變所引起的，其中大部分傳統療法無法治癒。通過基因篩查，也就是通過檢測分析父母雙方的基因組，可以得知將來後代罹患某些遺傳疾病的風險，從而作出優生優育的理性抉擇。不過基因篩查在預防兒童罹患遺傳疾病上並非完全有效，而且目前除了利用基因篩查對遺傳疾病採取預防措施外，這些疾病尚無有效的治療手段。因此，Editas作為一家基於CRISPR基因編輯技術的初創公司，同Intellia Therapeutics和CRISPR Therapeutics公司一樣，希望利用CRISPR基因編輯技術研發出一些遺傳疾病的新型治療手段。Katrine Bosley表示，由於CRISPR可以修正缺陷基因，有望用其來治療由基因缺陷造成的大量遺傳疾病。
據報道，Editas公司計劃用CRISPR基因編輯技術來治療一種罕見的眼疾：雷伯氏先天性黑內障。該疾病對眼睛的視網膜產生破壞性影響，患者天生只能看到大且明亮的物體。患上雷伯氏先天性黑內障的後果非常嚴重，患兒的視力低下到與失明無差異。
遺傳疾病數量非常多，那麼，Editas公司為什麼選擇雷伯氏先天性黑內障作為主攻目標呢？其一是基因編輯的標靶好定位。理論上，通過將攜帶CRISPR-Cas9的改良病毒直接注射進病人的視網膜並清除導致疾病的「元兇」CEP290基因，就能治癒該疾病。其二是治療效果好檢驗。由於該病和視力密切相關，可以很容易地檢驗治療成功與否。Katrine Bosley表示，「選擇雷伯氏先天性黑內障的部分原因是CRISPR容易解決該疾病的致病缺陷，導致該疾病的基因缺陷已經確定。」 Katrine Bosley也坦承，目前的治療方案是會能起效以及否會產生副作用尚不能確定。Bosley表示在進行人類試驗之前，仍需要在動物身上進行大量的測試。
Editas medicine公司位於美國馬薩諸塞州劍橋市，成立於2013年11月，創始人包括Feng Zhang，Jennifer Doudna等，而這兩人也是CRISPR技術的最初研發人員。今年8月該公司獲得1.2億美元的B輪融資，由Boris Nikolic領投，比爾•蓋茨、Google Ventures等跟投，以資助其利用基因編輯技術對雷伯氏先天性黑內障等遺傳疾病展開治療試驗。

⑤ 呼嘯山莊主要內容英文版

19世紀，在英國約克郡一個陰沉的荒原邊上，一個名叫希斯克利夫的吉普賽男孩，被迪恩先生帶到咆哮山莊。

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.

他得到主人之女凱西的鍾愛，凱西在愛的同時，又無法拒絕自己想過優裕生活的願望，而能提供這種生活條件的是鄰居艾德加·林頓。希斯克利夫得知後，悄然離去，凱西嫁給了林頓。

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.

希斯克利夫回來了。林頓的妹妹伊貝拉愛上了他，他買下了咆哮山莊。他與伊莎貝拉結婚以後，希斯克利夫的冷淡無情使伊莎貝拉很快枯萎掉謝，凱西也因為悲傷過度而瀕臨死亡。

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.

希斯克利夫在凱西彌留之際來到她身邊，把她抱到窗前姚望那方岩石——童年時代那曾是他們的「城堡」凱西說她等待著，總有一天他們會團圓，然後死去。

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.

希斯克利夫心神錯亂，在哀悼凱、期待死亡中捱過了20年。他對周圍一切人都極端輕蔑、百般折磨，直到凱西的幽靈在一個嚴冬的雪夜把他召喚到他們最喜愛的荒原上某個地方，在死亡中重新聚會……

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...

寫作背景：

艾米麗生性寂寞，自小內向的她，緘默又總帶著幾分以男性自居的感覺，在她寫作《呼嘯山莊》時，這種困惑與不安的情緒變得更加急躁。

她迫切需要創造一個虛構的世界來演繹它，把自己心底幾近撕裂的痛苦借小說人物之口淋漓盡致地發泄出來。因此《呼嘯山莊》是飽含作者心血與情感的作品。

⑦ 12306訂票怎麼選擇上下鋪

12306訂票鋪位是系統隨機發放的，無法人為設定選擇上下鋪。如果因特殊原因和喜好限定某一鋪位，可以帶上乘車人和買票人的身份證到就近的車站售票廳或車票代售點購買。如果票充裕，都會買到想要的鋪位。

網上購票，系統隨機刷出來的座位和鋪位都不一定是想要的。拿硬卧來說，系統對於卧鋪是平均分配的。買一張基本上是上鋪；買兩張一般是上、中各一張或上、下各一張；買三張的時候上、中、下各一張。
