　　(A) 正確, 句子結(jié)構(gòu)簡(jiǎn)潔, 意思表達(dá)清晰且用詞符合習(xí)慣

　　(B) the solar system's largest planet同位語(yǔ)結(jié)構(gòu)無(wú)法修飾Jupiter's mass; 在gas spheres that are estimated at 5 to 15 times the mass of Jupiter比較結(jié)構(gòu)中,gas spheres和the mass of Jupiter不對(duì)應(yīng),無(wú)法進(jìn)行比較

　　(C) 更改了原句的意思working本來(lái)是修飾成分,用來(lái)修飾astronomers,在這里變成了句子的謂語(yǔ),has detected本來(lái)是原句的謂語(yǔ)動(dòng)詞,在該選項(xiàng)中做修飾成分,變成了附屬結(jié)構(gòu); spheres that are estimated at 5 to 15 times結(jié)構(gòu)復(fù)雜,that are可以去掉; gas spheres和the mass of Jupiter不對(duì)應(yīng),無(wú)法進(jìn)行比較

　　(D) and has detected沒(méi)有能夠與之平行的對(duì)象; 比較雙方不對(duì)應(yīng)
