英语翻译What devices that were used to keep us safely within our

2个回答

  • 我的理解是:

    What (devices that were used to keep us safely within our boundaries) are we hanging on to (that prevents us from advancing)?

    主体结构是:what devices are we hanging on to?

    哪些装置是我们目前还紧抓不放的(这些装置过去用于保护我们在一定范围内得到安全),而这样的情况会阻止我们进步.

    其中,后一个that是定语从句的引导词,修饰这种情况

    仅供参考.
