20世纪的战争与和平

材料一1918年3月15日，根据列宁的建议，全俄苏维埃第四次非常代表大会以压倒多数批准了《布列斯特和约》。3月17日，《布列斯特和约》也经德国批准并开始生效。《布列斯特和约》使苏俄丧失了100万平方公里、相当德法两国领土总和的土地，将近5000万人口，损失了煤占全国90%、铁矿占73%、工业设备占全俄的1/3、铁路的33%，还有大量赔款。

材料二1922年4月16日，德国、苏俄在热那亚近郊拉巴洛签订了《拉巴洛条约》，该协定共六条，主要内容是：（一）相互放弃要求赔偿战争费用、战争损失及战俘费用的权利。（二）德国放弃因俄国实行国有化对德国国家财产和私有财产造成损失的赔偿要求，但以俄国也不给予第三国同类赔偿为条件。（三）两国立即恢复外交关系和领事关系。（四）两国根据平等互利和最惠国原则建立贸易和经济关系。缔约后，1922年德国对苏出口增加1倍多，从苏进口增加了13倍。列宁认为它体现了“两种所有制的真正平等”。

    Time managements is the greatest challenge for me in high school．I have to take good care of my subjects, activities, social life and rest．I was often angry with my family members just because I didn't plan my time well．For example, I might shout at them for troubling me when I was working．And sometimes I might say something bad to them when I missed deadlines, even if it was actually my fault for cramming everything in (把所有的事情堆积起来) at the last minute．

    As time goes by, I realize that time management is very important in our everyday life．The best advice to deal with time management is "break it into bits"．It's really important for you to learn how to break a big project into small, manageable tasks．Then you can work progressively and have a sense of achievement whenever you've done with a small part．

    Another piece of advice is to plan a timetable for yourself．It doesn't have to be the one that you follow completely．It's just there to serve as a guide．You can compare your actual timetable with the planned one to see how well you actually use your time．The final suggestion is to always set deadlines for yourself．
