理工類輔導資料：疑難問題解答making systems

　　學員提問：老師，您好！全文最后一句話“making systems that get warnings to those”怎么分析？謝謝

　　名師解答：

　　你問的是閱讀理解第三十六篇文章最后一句話。

　　這句話的主干是： making systems.......can be difficult.

　　其中，that get warnings to those who need them 是定語從句，修飾systems

　　在這個從句中those 指代上文提到的“人們”who 引導的定語從句who need them修飾those，指的是需要得到預警的人們。

　　所以，這句話的意思是：使系統發射的預警送達到需要的人群是不容易的。

　　the device is currently being tested in a 6-metre-tall artificial clay embankment in newcastle， uk. early results suggest it should provide fewer false positives than existing systems. once it has been carefully and thoroughly tested， the device could be used to create a complete early-warning system for dangerous slopes.

　　“locations with a significant risk of landslides could definitely benefit from a machine like this， ” says adam poulter， an expert at the british red cross. “as long as it doesn’t cost too much.” but， poulter adds that an early-warning system may not be enough on it own. “you need to have the human communication，” he says. “making systems that get warnings to those who need them can be difficult.”
