单选题 Scientists call on us to ______ nature and become better recyclers.
  • [A] learn of
  • [B] learn to
  • [C] learn about
  • [D] learn from


【正确答案】 D
【答案解析】[解析] 考查动词搭配。learn可作及物和不及物动词,作及物动词时,可直接跟学科、the news及从句,作不及物动词时多与of/about/from等连用或跟不定式。learn of得知,获悉;learn about学习,学到,得知;learn to后跟动词原形;learn from从…中学习,从…中得到经验。本题宾语是nature(自然),故除[D]外,其余三项都不合适。
