答案:
B
選B. 主干是
Travelers would have to endure ..., avoiding ..., plus contending .., and ward off.邏輯為:旅行者從地球到火星將不得不忍受低重力,避免輻射,加上與化學(xué)反應(yīng)的競(jìng)爭(zhēng),甚至可能阻止..的污染。原文4個(gè)動(dòng)作平行,邏輯合理,但語法錯(cuò)誤,plus不是連詞,未劃線部分的ward off和前面的contending,avoiding,endure不平行。 B項(xiàng)endure,avoid,content,ward off平行。 C項(xiàng)跳過having to endure,謂語接的是would also have to avoid ,改變邏輯,且和后面的ward off不平行。 D項(xiàng)同C,跳過having to,謂語改變,plus不是連詞。 E項(xiàng)缺謂語,改變邏輯。
