填空题 Companies and individuals who don't have a strategy to export more, or to 1 (involve) in foreign markets, are shutting themselves out of the lion's share of economic opportunity in our world.
  • 1、
【正确答案】 1、get more involved    
【答案解析】[解析] 该句是一个复杂句，由主句和定语从句构成。从句的主语“who”即“Companies and individuals”是动作“involve”的承受者，故使用被动语态。根据句意，强调的是动作的发生而非动作的持续状态，故使用“get involved”。通过“export more”的提示可知此空应表达“更多”之意，因此此空应填get型被动语态的比较级。
