该怎么样解决这个问题。

1. A。

细节理解题。

根据第一段第三句“The country’s farmers a re getting older, and there are fewer people standing in line to take their place”可知，A项正确。

2. D。

细节理解题。

根据第二段第一句中“…is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture”可知，D项正确。

3. C。

推理判断题。

根据第五段中“Global demand is at an all-time record high, and global supplies are at all-time record lows”可推断Matt Rush认为，全球对农业的需要达到了最高，而全球的供应则达到了最低，故在农业上投资肯定会获利，即C项正确。

4. C。

句意理解题。

根据最后一段第二句中“…this is a new time in agriculture —will motivate the next generation…”可推断此处表示的是“农业的新时机将会激励下一代来参与，即农民的平均年龄将会年轻化”，故C项正确。

BA team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components(元件),” said Robert Wood, the Harvard eng ineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those compone nts are off the shelf and so we have to develop them all on our own,” he said.They engineered a series of systems to start and drive the robotic fly. “The seeminglysimple system which just moves the wings has a number of interdependencies on theindividual components, each of which individually has to perform well, but then has to be基础题：(A)Fighting for Scientific ProgressIN the eyes of her daughter, He Zehui was a “simple, ordinary(普通的) old lady, who lived a low-key life”.
