保持愉快的沟通：尤其是上了幼儿园之后，每天都要找时间与孩子沟通，聊一聊幼儿园的各种事情，学习情况、好玩的玩具、八卦。用来掌握孩子在幼儿园的情况，从一些小事和孩子对事件的反应中，能了解孩子在幼儿园是不是受到欺负或者不公正的待遇，这也是初步跟孩子建立信任的时候，我会当一个合格的倾听者，让孩子愿意跟我交流。

This is how it works now:
If they have time, astronauts and cosmonauts will look to plug the leak or close the hatch to the leaking section of the station. (That is how they dealt with a minor leak in the station’s PrK module for a number of years, and it basically worked.) Remember, though, that this is the worst-case scenario, and our crew will run into a hard deadline. Once pressure falls to around 490 mm Hg, NASA says, critical systems risk breaking down. Astronauts could suffer hypoxia, oxygen deprivation so debilitating they could become delirious. It will be a heart-wrenching call, but if nothing else can be done, the crew will need to go to their crew vehicles and leave the ISS.
