两道英语语法题.
1.withmoreforestsbeingdestroyedinthatarea,hugequantitiesofland_______desertseachyear.
A.hasbeenturnedintoB.arebeingturnedinto.
为什么答案是B可以理解正在转变为沙漠,但为什么A不可以,它不是表示从以前开始,并延续下去,且侧重对事物的影响吗?这不是A更确切?
2.thesuperhybridricearoundtheworld_______thelivesofmillionsofpeoplesufferingfromhungertoagreatlevel.
A.haveimprovedBhadbeenimproving.
A和B到底有什么区别啊?应该选哪个?
