Daily Mail of November 25th reported that American astronomers （天文學(xué)家）______aplanet that was most similar to the earth.
A．discoveredB．inventedC．foundD．noticed
A

試題分析：句意:11月25日的Daily Mail 報(bào)道說美國的天文學(xué)家發(fā)現(xiàn)了一顆與地球最相似的行星。discover 發(fā)現(xiàn)，指發(fā)現(xiàn)早已存在的事物；invent 發(fā)明，指發(fā)明以前沒有的事物；find 發(fā)現(xiàn)，找到，指找到丟失的東西，或發(fā)現(xiàn)事實(shí)的真相；notice 注意。根據(jù)句意可知這顆行星早已存在，只不過沒有被人們所發(fā)現(xiàn)。故應(yīng)該用discover。
