Question

12．科学家应该投入更多的精力来研发能在火星上生长的植物．
Scientists shouldput more effort into developingthe plants that can grow on Mars．

Answer 1

分析 put more effort into developing．

解答 答案：put more effort into developing．句中的should是情态动词，后加动词原形，在…付出努力用put effort into…，这里是投入更多的努力用much的比较级more更多（much修饰不可数名词effort），into是介词，后加名词代词或动名词，研发develop动词，故答案是put more effort into developing．
