Question

【題目】 They're life jacket orange, they’re robots and they're capable of sailing the high seas without human intervention.

On Tuesday the National Oceanic and Atmospheric Administration (NOAA) launched a pair of Saildrones(海洋無人機(jī)) in Pacific Northwest waters for the first time. Their summer long sailing journey will stretch from Vancouver Island to California. The Saildrone operators will collect data to help set future fishing seasons. The government wants to see whether seagoing. robots can extend fishery surveys now performed by expensive manned ships.

Nora Cohen from NOAA said,“The 23 foot tong seagoing robots can follow a remotely programmed course for up to a year at a time. And they don't require any fuel. We use wind and solar power to drive the sensors.”He added,“It means that we're able to go to places where we don't really want to send people, and go into weather that we really don't want anyone ever to be in, and be able to send back measurements.”

The primary mission is to investigate the species and number of fish in existence and the places where they are. Larry Hufnagle, scientist of NOAA Fisheries in Seattle, said a traditional big NOAA research ship-based survey costs around $25，000 per day. By comparison, one Saildrone runs $2,500 per day.

“It could be a significant saving,”Hufnagle said. “But like anything else, there is a tradeoff in what you get and what you don't get. On the manned ship, we have limited time. It takes a lot of people. We spend a fair amount of money. But there is one thing the Saildrone can't do that humans can: cast a net to catch and positively identify the fish detected below. The Saildrones are going to give us additional data, not replacement data.”

Nora Cohen said Sail Drone, a venture capital-backed company based in Alameda, California, expects to launch a total of 11 of its seagoing robots to survey different water bodies for NOAA this year. The Bering and Arctic seas, coastal California and Gulf of Mexico will be the locations of additional missions.

Answer 1

【答案】

【1】B

【2】A

【3】D

【4】A

【解析】

這是一篇說明文。介紹了海上無人機(jī)的引入將給人類帶來的好處。

【1】

細(xì)節(jié)理解題。根據(jù)關(guān)鍵詞collecting fish data可以定位文章第二段第三句The Saildrone operators will collect data to help set future fishing seasons. 無人機(jī)操作員將收集數(shù)據(jù)，幫助設(shè)定未來的捕魚季節(jié)�？梢缘贸�。收集數(shù)據(jù)是幫助設(shè)定未來的捕魚季節(jié)。選線B和文意相符。故選B項(xiàng)。

【2】

主旨大意題。結(jié)合題干定位第三段。本段講解的是：國家海洋和大氣局的諾拉 · 科恩說23英尺長的海洋機(jī)器人，可以進(jìn)行遠(yuǎn)程程序控制，每次航行長達(dá)一年。 它們不需要任何燃料。 “我們用風(fēng)能和太陽能驅(qū)動傳感器” 他補(bǔ)充說，“這意味著我們可以去到我們不想派人去的地方，去到我們真的不想讓任何人去的天氣，并且可以發(fā)回測量數(shù)據(jù)�！睋�(jù)此可以得出，本段主要講述的是海洋機(jī)器人的優(yōu)勢。選項(xiàng)A符合文意。故選A項(xiàng)。

【3】

詞義猜測題。根據(jù)關(guān)鍵詞可以定位到文章第五段第二句But like anything else, there is a tradeoff in what you get and what you don't get，結(jié)合本段第一句“It could be a significant saving,” 這可能是一個(gè)重大的節(jié)省。知道了使用無人機(jī)能節(jié)省很多錢。理解本段第六句But there is one thing the Saildrone can't do that humans can: cast a net to catch and positively identify the fish detected below. 但有一件事情，帆船不能做到，人類可以: 撒網(wǎng)捕捉，并肯定地識別下面檢測到的魚�？芍�，人類能做的事情在無人機(jī)這卻不能實(shí)現(xiàn)。對比理解，即可推斷出對與無人機(jī)而言，人類從其處能得到的和不能得到的這就是一種平衡。據(jù)此可以得出“tradeoff”意思是平衡。故選D項(xiàng)。

【4】

推理判斷題。根據(jù)最后一段內(nèi)容：諾拉 · 科恩說，總部位于加州阿拉米達(dá)的風(fēng)險(xiǎn)投資公司 Sail Drone 預(yù)計(jì)今年將推出11個(gè)航海機(jī)器人，為 NOAA 勘測不同的水域。 白令海和北冰洋，加利福尼亞海岸和墨西哥灣，將是其他任務(wù)的地點(diǎn)。據(jù)此可以得出，Sail Drone海上無人機(jī)的前景比較光明。選項(xiàng)A符合題意。故選A項(xiàng)。
