Driverless taxis will soon be available for hire

無人駕駛出租車將投入運營

Self-driving taxis were rolled outon a trial basis in Beijing followinga series of road tests， which wereconducted with safety supervisorson board. Baidu and Pony. ai wonpermits back then to operate driverless taxis through their ridehailingapps within a 60-square-kilometer area in Yizhuang， locatedin the southern suburbs of Beijing.

During the commercial run of driverless taxis， more attentionwill be paid to the assessment of service capabilities of autonomousmobility companies， with the focus being on reviewing three riskaspects — passenger safety， traffic conditions and autonomousdriving functions. At the same time， tailored daily supervision andemergency plans will be formulated for the unmanned commercialfleet to ensure that these vehicles run smoothly and safely on roads.China has opened up a road network of more than 15，000 km to testintelligent vehicles， including taxis and buses， involving multiple selfdrivingscenarios such as autonomous valet parking and unmanneddelivery.

在進行了一系列道路測試后，北京啟動了“車內無人”載人示范應用，所有測試在安全監(jiān)督員的指導下進行。百度和小馬智行獲得了許可，在北京南郊亦莊60 平方千米范圍內劃定區(qū)域通過叫車應用軟件開展無人自動駕駛運營示范。

無人駕駛出租車在邁入商業(yè)化試點新階段，將更加注重對自動駕駛企業(yè)服務能力的評定，主要圍繞乘客車內安全風險、交通環(huán)境風險、自動駕駛功能風險三方面進行評估。同時，政府將針對試點車輛制定日常監(jiān)管專項及應急預案，確保這些車輛在道路上平穩(wěn)安全運行。目前全國已開放智能網(wǎng)聯(lián)汽車測試道路超過15000 千米，包括出租車和公交車在內的智能車輛，還涉及自動代客泊車、無人配送等多個自動駕駛場景。

Fill in the blanks：

Daily supervision and emergency plans will be formulated to ensure that driverless taxis _______________ smoothly and safely on roads.

Climate change has caused oceans become greener

氣候變化使海洋變綠

The color of the ocean has changed significantly over the last20 years and human-caused climate change is likely responsible，according to a new study. More than 56% of the worlds oceanshave changed color to an extent that cannot be explained by naturalvariability， said a team of researchers， led by scientists from the?National Oceanography Center in theUK and the Massachusetts Institute ofTechnology in the US， in a statement.Tropical［ 熱帶的］ oceans close to theequator in particular have becomegreener in the past 2 decades， reflecting changes in their ecosystems，according to the study published recently in the journal Nature. Oceanecosystems are finely balanced and any change in the phytoplanktonwill send ripples across the food chain. All changes are causing animbalance in the natural organization of ecosystems. Such imbalancewill only get worse over time if our oceans keep heating.

While the researchers are still working to unpick exactly what thechanges mean， what is clear， they said， is that the changes are beingdriven by human-induced climate change. The researchers monitoredchanges in ocean color from space by tracking how much green orblue light is reflected from the surface of the sea. They analyzed colorvariation data in the past 2 decades and then used climate changemodels to simulate what would happen to the oceans both withadditional planet-heating pollution and without. The color changesmatched almost exactly what researchers predicted would happen ifgreenhouse gases were added to the atmosphere that around 50% ofour oceans would change color.

一項新研究發(fā)現(xiàn)，海水顏色在過去20 年里發(fā)生了顯著改變，很可能是受到了人為導致的氣候變化的影響。英國國家海洋中心和美國麻省理工學院的科學家?guī)ьI的研究團隊稱，全世界超56% 的海水顏色在一定程度上發(fā)生了無法用自然變異來解釋的改變。近期發(fā)表在《自然》期刊上的研究報告指出，尤其是靠近赤道的熱帶海洋，它們在過去20 年里變得更綠了，這反映出它們海域生態(tài)系統(tǒng)的改變。海洋生態(tài)系統(tǒng)處于微妙的平衡狀態(tài)，浮游植物的任何變化都會在整個食物鏈中產生連鎖反應。所有的變化都會導致生態(tài)系統(tǒng)的自然組織失去平衡。如果我們的海洋持續(xù)升溫，這種不平衡隨著時間的推移只會變得更糟。

盡管研究人員仍在努力解開海洋顏色變化之謎，但是他們表示有一點是明確的，這些改變是由人為導致的氣候變化推動的。研究人員通過空間站跟蹤記錄從海面反射的綠光或藍光量來監(jiān)測海洋顏色的變化。他們分析了過去20 年的海洋顏色變化數(shù)據(jù)，然后使用氣候變化模型來模擬海洋在有溫室氣體污染和沒有污染的情況下會發(fā)生什么。結果海洋顏色變化幾乎與研究人員預測的完全一致，當大氣中加入溫室氣體時，大約50% 的海洋會改變顏色。

The most leaning tower of Abu Dhabi

最斜建筑：阿布扎比斜塔

Leaning tower of Abu Dhabi， is a skyscraper in the emirate thatis more than 160 meters tall， 35 stories high， and with more than16，000 square meters of office space. It is one of the tallest buildingsin the city and was designed to incline 18 degrees west. Calling it askyscraper does not quite capture its true essence［精髓；本質］. The briefgiven to the engineers and architects was not to make the biggest ortallest building around， but to “challenge the rules of architecture andto build a structure that would put Abu Dhabi on the world map”， says?Ahmed Al Mansoori， a lead engineer for Capital Gate and director ofengineering for the company Abu Dhabi National Exhibitions.

The United Arab Emirates（UAE） ranks third equal internationallyfor the place with the most number of skyscrapers， sharing that spotwith Japan， both having 251 buildings taller than 150 meters. Thenumber one spot is held by China with 2，055 buildings taller than 150meters， followed by the US with more than 800. The tallest buildingsin the UAE after Burj Khalifa are： Marina 101 at 426.5 m， PrincessTower at 413.36 m， 23 Marina at 395 m， and Burj Mohammed BinRashid in Abu Dhabi at 381.2 m.

阿布扎比斜塔，是阿聯(lián)酋的一座摩天大樓，高160 多米，35 層高，辦公面積超過1.6 萬平方米。它是這個城市最高的建筑之一，設計成向西傾斜18°。將它稱為摩天大樓并沒有完全抓住其真正本質。阿布扎比斜塔的首席工程師、阿布扎比國家展覽公司的工程總監(jiān)艾哈邁德·阿里·曼蘇里表示，給工程師和建筑師的任務不是建造周圍最大或最高的建筑，而是“挑戰(zhàn)建筑規(guī)則，建造一個能讓阿布扎比在世界地圖上出現(xiàn)的建筑”。

目前阿聯(lián)酋與日本并列為世界上摩天大樓數(shù)量第三多的國家，擁有251 座150 米以上的摩天大樓。排名第一的是中國，有2055 座摩天大樓，其次是美國，有超過800 座摩天大樓。阿聯(lián)酋最高的建筑為哈利法塔，其次是港灣101 大樓，高度為426.5 米；迪拜公主塔，高度為413.36 米；瑪麗娜23 大廈，高度為395 米；以及阿布扎比的穆罕默德·本·拉希德（世貿中心）大廈，高度為381.2 米。
