A 12-year-old girl who was visiting the United States from China was believed to be abducted by a woman at Ronald Reagan Washington National Airport on Thursday morning, officials say.

據(jù)官方消息，當?shù)貢r間8月2日上午，一名從中國來美國旅游的12歲女孩疑似在華盛頓里根國家機場遭到一名女子綁架。

The girl, JinJing Ma, is believed to be in "extreme danger," Virginia State Police said in a statement. The FBI is involved in the investigation, and state police said they are contacting the Chinese embassy.

弗吉尼亞警方發(fā)布警報說，這位名叫馬金晶（音譯）的女孩處境“極度危險”。聯(lián)邦調(diào)查局已介入調(diào)查，弗吉尼亞警方稱，正在聯(lián)系中國大使館。

Law enforcement officials in the DC area issued an Amber Alert.

華盛頓地區(qū)執(zhí)法人員發(fā)布了安伯警報（譯者注：美國兒童安全警報系統(tǒng)）。

Ma was last seen at the airport at 8:15 a.m. She was traveling with a group and met with a middle-aged woman, who also was visiting from China.

馬金晶于8:15最后一次出現(xiàn)在里根國家機場。她隨一個中國旅游團來美旅游，與一名中年女性會合，這名女性也是從中國來美旅游。

The girl and the woman both changed clothes, walked to the arrivals area of the airport and disappeared out of the view of security cameras, police said.

警方表示，馬金晶和這名女性都換了衣服，兩人一起走到機場的到達區(qū)后，最終從監(jiān)控中消失。

They are believed to be riding in a white 2016 or 2018 Infiniti QX70 with New York plates that a man is driving. Investigators are working to identify the license plate number, the Washington Metropolitan Airports Authority said late Thursday night.

兩人被看到乘坐一輛掛著紐約牌照的白色2016或2018款英菲尼迪QX70汽車，由一名男子駕駛。華盛頓都會區(qū)機場管理局2日晚表示，偵查員正在識別車牌號。

Ma stands 4-foot-11 and weighs 90 pounds. She has brown eyes and black hair. She was last seen wearing a white T-shirt, jeans and a black jacket.

馬金晶身高4英尺11英寸（約1.5米），體重90磅（約40公斤），黑頭發(fā)，棕色眼睛。最后一次露面時身穿白色T恤、藍色牛仔褲和黑色外套。

The woman, whose name police did not release, stands 5 feet tall and was wearing a black dress.

警方并未公布這名女性的名字，她身高5英尺（約1.52米），身著黑色連衣裙。

Later Thursday night, the Metropolitan Washington Airports Authority released more photos, including the photo of the woman suspect and a man arriving at the airport's ticketing and departures level.

The head of Malaysia’s civil aviation regulator has resigned after an official report found failings in air traffic control when flight MH370 disappeared.

一份關(guān)于MH370航班客機失事的官方調(diào)查報告稱，飛機失事時，航空管制中心存在疏漏，馬來西亞民航局局長已提出辭職。

In a long-awaited report released on Monday, the official investigation team pointed to numerous lapses by air traffic controllers in both Malaysia and Vietnam, which ensured the plane was missing for about 20 minutes before an alert was sent.

這份眾盼已久的報告于7月30日發(fā)布，官方調(diào)查團在報告中指出，馬來西亞和越南空管部門存在諸多過失，直到飛機大約失聯(lián)20分鐘后才加以確認并發(fā)出警報。

In the 495-page report, investigators said they still did not know why the plane vanished, leaving families of those onboard devastated and highly critical of the investigation.

調(diào)查人員在495頁的報告（譯者注：該報告共822頁，主體部分共495頁）中依然沒有查明飛機失蹤的原因，乘客家屬對調(diào)查結(jié)果極為不滿，陷入崩潰。

The safety investigating team, however, did officially conclude that the course of the Malaysia Airlines aircraft was changed manually, rather than due to autopilot mechanisms.

但安全調(diào)查團正式宣布，MH370被人為改變航線，并非由于自動駕駛儀出現(xiàn)機械故障。

After investigations demonstrated that the pilot had been both adequately trained and under no pressures or mental strain that could have led him to crash the plane on purpose in a suicide mission, Dr Kok Soo Chon, the investigator in charge of the MH370 safety investigation, said “interference by a third party” could be a reason the jet suddenly diverted off course.

調(diào)查表明，兩名飛行員均受過嚴格訓練，不存在壓力或精神緊張，以致作出故意墜機的自殺舉動。負責MH370安全調(diào)查的郭師傳稱，“第三方干擾”或許是飛機突然偏離航線的原因。

The transport minister, Anthony Loke, said on Monday that “the aspiration to locate MH370 has not been abandoned” and vowed to take action against any misconduct committed based on the findings.

馬來西亞交通部長安東尼·洛克7月30日表示，“不會放棄搜索MH370的位置”，并采取行動堅決反對調(diào)查結(jié)果涉及的不當行為。

China's markets regulator said on Wednesday it has asked Shanghai regulators to investigate online discounter Pinduoduo Inc following media reports of counterfeit goods and intellectual property infringements.

據(jù)媒體報道，折扣電商拼多多公司涉嫌銷售侵權(quán)假冒商品，中國市場監(jiān)管總局8月1日表示，已要求上海相關(guān)監(jiān)管部門展開調(diào)查。

The move comes after the Chinese e-commerce start-up raised $1.63 billion last week in the second-biggest U.S. listing by a Chinese firm this year, which valued the company at $23.8 billion.

上周，這家中國電商初創(chuàng)公司融資16.3億美元（約合人民幣111億元），市值達238億美元（約合人民幣1623億元），成為今年在美國上市的第二大中國公司。

Regulators will interview the Shanghai-based platform's operators and will deal seriously with any illegal practices found on the platform, the State Administration for Market Regulation said on its website.

國家市場監(jiān)管總局官網(wǎng)發(fā)布消息稱，監(jiān)管部門將約談上海拼多多平臺經(jīng)營者，只要平臺構(gòu)成違法，將依法嚴肅處理。

Pinduoduo is known for running large campaigns with extremely low-priced products to lure consumers – and has faced criticism for allowing misleading goods to be sold to consumers in some instances, mostly in China’s countryside.

拼多多因用價格極低的商品吸引消費者而聲名鵲起，同時也因向消費者（主要集中在中國農(nóng)村地區(qū)）出售山寨商品而備受詬病

Serial entrepreneur Huang Zheng, the founder of Pinduoduo, said counterfeit goods remain an unavoidable problem in China amid the steady development of the country’s online retail market.

拼多多創(chuàng)始人、連續(xù)創(chuàng)業(yè)者黃崢表示，在中國線上零售市場平穩(wěn)發(fā)展的今天，山寨貨依然是不可避免的問題。

Dozens of people were injured when a packed Aeromexico-operated Embraer jet crashed right after takeoff in Mexico's state of Durango on Tuesday, but authorities said most were not seriously hurt and there were no fatalities.

當?shù)貢r間7月31日，墨西哥航空公司運營的巴西航空公司一架載滿乘客的飛機起飛后不久，在墨西哥杜蘭戈州墜毀，數(shù)十人受傷。但官方表示，機上大部分人員受輕傷，沒有人員死亡。

The mid-sized jet was almost full, with 103 people including two infants and four crew members on board, when it crashed at about 4 p.m. local time (2100 GMT), authorities said. Passengers and crew jumped to safety before the plane was engulfed in flames. The pilot was the most severely hurt but was in a stable condition.

據(jù)官方消息，這架中型客機當時共搭乘103人，基本滿員，包括兩名嬰兒和四名機組人員，飛機于當?shù)貢r間下午4點墜毀。在飛機被大火吞噬前，乘客和機組人員跳下飛機安全逃生。機長傷勢最為嚴重，但目前情況已經(jīng)穩(wěn)定。

Passenger Jackeline Flores told reporters the plane crashed shortly after taking off in heavy rain.

一位名叫Jackeline Flores的乘客在接受采訪時說，飛機在起飛后不久便遭遇暴雨落地墜毀。

TV images showed the severely damaged body of the plane after it came to rest in scrubland and a column of smoke rose into the sky.

從電視畫面上來看，飛機墜入灌木叢后機體嚴重損毀，一股濃煙騰空而起。

28 of China’s province-level administrative entities have released their GDP figures for the first half of 2018 to reveal that Guangdong is China’s largest regional economy while Guizhou province has seen the most rapid growth.

近日，中國28個省份公布了2018年上半年GDP數(shù)據(jù)，廣東經(jīng)濟總量最大，貴州經(jīng)濟增速最快。

Guangdong province’s first half GDP reading of 4.634193 trillion yuan put it first out of the 28 provinces that have released data, followed by Jiangsu province in second place, with a figure of 4.48635 trillion yuan.

廣東省上半年經(jīng)濟總量為46341.93億元，在已公布的28個省份中排名第一，江蘇以44863.5億元排名第二。

Shandong came in third place, followed by Zhejiang in fourth, Henan in fifth, Sichuan sixth, Hubei seventh, Hebei eighth, Hunan ninth and Shanghai tenth.

山東、浙江、河南、四川、湖北、河北、湖南、上海分列第三位至第十位。

15 of the 28 Chinese province-level entities outpaced the nationwide growth rate of 6.8%.

28個省份中有15個省份的GDP增速超過全國6.8%的平均增速。

Guizhou saw the most rapid GDP growth with an increase of 10%, making it the sole Chinese province to see double digit expansion in the first half.

貴州以10%的經(jīng)濟增速排名第一，成為上半年唯一增速“上雙”的省級區(qū)域。

Yunnan took second place at 9.2%, while Jiangxi, Shaanxi, Anhui, Fujian and Sichuan all posted growth in excess of 8%.

云南以9.2%的增速排名第二，增速高于8%的還有江西、陜西、安徽、福建、四川。

Jilin, Xinjiang and Tibet have yet to release their GDP data for the first half of 2018.

目前，僅吉林、新疆與西藏尚未公布2018年上半年的經(jīng)濟運行情況。

Brewer's yeast, one-third of whose genome is said to share ancestry with humans, has 16 chromosomes. However, Chinese scientists have managed to fit nearly all its genetic material into just one chromosome while not affecting the majority of its functions, according to a paper released Thursday on the website of the journal Nature.

具有16條染色體的釀酒酵母中有1/3的基因與人類基因同源。然而，8月2日在《自然》雜志網(wǎng)站上發(fā)表的一篇論文稱，中國科學家成功將釀酒酵母幾乎所有的遺傳物質(zhì)整合為單條染色體，且不影響其大部分功能。

Qin Zhongjun, a molecular biologist at the Center for Excellence in Molecular Plant Sciences of the Shanghai Institute of Plant Physiology and Ecology under the Chinese Academy of Sciences, and his team used CRISPR-Cas9 genome-editing to create a single-chromosome yeast strain, the paper said.

中國科學院上海植物生理生態(tài)研究所分子植物科學卓越創(chuàng)新中心的分子生物學家覃重軍和他的團隊使用CRISPR-Cas9基因組編輯技術(shù)創(chuàng)建了單條染色體酵母菌株。

Yeast is a type of eukaryote, which also includes humans, plants, and animals. Humans have 46 chromosomes, whereas male jack jumper ants have just one. It seems that the number of chromosomes of a eukaryote has no correlation with the amount of genetic information they possess, the paper said.

酵母和人類、動植物一樣，都是真核生物。人類有46條染色體，而雄性杰克跳蟻只有一條。論文提到，真核生物的染色體數(shù)目似乎與他們所攜帶的遺傳信息數(shù)量沒有相關(guān)性。

"It overturns the traditional view that gene expression is determined by the structure of chromosomes," Qin said.

覃重軍說：“這顛覆了染色體結(jié)構(gòu)決定基因表達的傳統(tǒng)觀念。”

The research may also pave the way for new man-made species in the future. "Yeast has great tolerance in genetic modification, and it is possible to add new chromosome segments to the genome. Researchers can make bolder attempts。" he said.

這項研究或許也為未來新的人造物種鋪平了道路�！敖湍笇�基因改造有很強的耐受性，并有可能在基因組中增加新的染色體片段。研究人員可以進行更大膽的嘗試�！彼�說。
