C
考查現(xiàn)在分詞。
由下文Anything on a turtle's shell,like algae (水藻),6 the turtle from swimming. It can also weaken the shell over time.海龜殼上的任何東西,比如水藻,阻止海龜游泳。隨著時(shí)間的推移,它也會(huì)使龜殼變得脆弱。And hardly(乎不)any of these turtles have kind people like you to help them clean their shells.這些海龜幾乎都沒(méi)有像你這樣善良的人來(lái)幫它們清理殼。結(jié)合選項(xiàng),可推測(cè)本句句意:“我在清理它們的殼,”她回答。
A訓(xùn)練 B打開(kāi) C清理 D采摘
故選C。
