【历史——选修3：20世纪的战争与和平】

材料：1940年7月底，德国秘密制定侵略苏联的计划……如何摆脱来自东方日本的威胁，重新成为苏联必须严重考虑的外交问题……还在1940年7月，日本大本营与政府联席会议通过了《适应世界形势演变处理时局纲要》，规定调整苏日关系以适应南进之需。1941年4月13日，苏联、日本达成了《苏日中立条约》。条约除了肯定双方保持和平友好关系，互相尊重领土主权完整，在一方与第三国发生军事冲突时保持中立以外，还特别声明：“日本须尊重蒙古人民共和国即外蒙古的领土完整和不可侵犯；苏联须尊重满洲国的领土完整和不可侵犯”。中国自然成为这两个国家相互妥协的最直接受害者……不过同时由于国际形势并未按苏联领导人的意志发展，苏联对华援助并未停止，延续到苏德战争爆发。条约稳定了苏联的东部边界，但激化美、英同日本的矛盾……太平洋战争爆发后，中国抗日战争的外援主要依赖美英。

    This study shows that people who use cell phones for about an hour a day have a 2 time hearing some similar sounds, especially in their right ears. It is getting harder for 3 to tell the differences between the sounds of “s” and “f”, and “t” and “z”.

    Researchers studied 100 people who used cell phones and 4 them with 50 people who did not. The study lasted for l2 months. What the researchers found was that cell phone users had more hearing 5 than those who did not use cell phones.

    Our ears have many little 6 inside them. Too much noise will cause these hairs to get weak and 7 die. When these hairs die, it affects our ability to listen.
