问题 A mussel grips a hard surface very firmly to ______. [br] To tie itself safely to a new home, a mussel must ______.
选项 A、produce a thread to anchor to the hard surface
B、draw air and water from its pad-like structure
C、hold down a tent as human beings do
D、place many anchor lines strategically
答案 D
解析 由题干To tie itself safely to a new home，a mussel must定位到原文第二段倒数第二句These strategically placed threads form a bundle，which ties the mussel to its new home in much the same way that ropes hold down a tent．推断题。本句是非限制性定语从句，which指代前面的句子，也就是选项D)所叙述的内容“战略性地摆放定位线”。[避错]A)“产生细丝铆钉在坚固的表面上”、B)“从他的微小垫状组织吸收空气和水分”和C)“类似于人类搭帐篷”，均与原文不符。
