 [答案解析]
21.d  考查動詞辨析，根據(jù)上下文，科學(xué)家應(yīng)該是投放(dropped)了90只玩具鴨子，所以選d。
22.b  從上文的“rubber ducks”可以看出來，這些都是玩具鴨子，所以用toys。
23.c  此處表達(dá)的意思為如果這些玩具鴨子被找到的話，科學(xué)家就能夠了解(learn)水是如何在冰與冰之間流動的，而且也能夠提供冰川運動(movement)的信息，所以選c。
24.b  參見第23題解析。
25.a  從上千文可知，這里科學(xué)家仍然不確知為什么冰川在夏季加速運動，向海洋流動，所以選a。
26.c  從上文“why glaciers speed up in summer and head towards the sea”可以推斷出，這里用speed up，表示“加速，加快”的含義。
27.b  jakobshavn冰川被認(rèn)為是撞沉titanic的冰山的源頭(source)，所以選b。
28.d  從語意來看，這里是說，robert jones說，還沒有鴨子被報道(reported)。也就是說，還沒有人揀到玩具鴨子，所以選d。
29.a  結(jié)合語境以及前面的動詞send可以看出，應(yīng)該是揀到的人給組織者發(fā)郵件(email)，告知已經(jīng)揀到，所以選a。
30.c  結(jié)合語境可知，人們還沒有揀到玩具鴨子是因為這些地方很偏遠(yuǎn)(remote)，以至于沒有多少人去過。
