（15分）材料一 近代中国外交中的重要条约、事件及影响

时间	事件或条约	影响
1842年	《南京条约》	“以前是中国处于命令的地位去决定国际关系”的局面发生了根本性转变
1895年	《马关条约》	中国面临着被“瓜分”的民族危机，传统的宗藩体制已经崩溃，华夷秩序几乎荡然无存
1900年	《辛丑条约》	中国完全陷入半殖民地半封建社会的深渊
1919年	巴黎和会	“中国与外国的条约关系，见证了一个时代的开始和另一个时代的结束”
1928年6月	“改订新约”运动	减少了一些帝国主义在我国长期享有的特权，否认了领事裁判权的合法性，增加了国家关税的收入，但又很不彻底
1943年1月	中英、中美签订新约	将上海及厦门公共租界之行动与管理权交与中国政府，凡关于上述租界给予英美政府之权益应予终止等
1949年9月	《共同纲领》	对国民党政府与外国所订立的各项条约和协定，中华人民共和国中央政府应加以审查，按其内容，分别予以承认，或废除，或修改，或重订

——根据《中国废除不平等条约的历史考察》中的有关内容编制

材料二 当时，在中国享有带有不平等性质的权益的国家主要是美、英、苏三家。在具体实践中，中国政府采取了不同的对策。美国是当时与新中国最为敌对的国家。中国政府对中美商约等一系列条约采取了不予承认的立场，美国此前在中国所享有的特权至此在大陆全部丧失。这种处理干脆利落。苏联是中国最重要的盟友。对于中苏友好条约，中国政府并没有断然宣布废除，而是积极地与苏联政府展开重新谈判。1950年2月，中苏订立了新的友好同盟互助条约及有关协定。协定规定在不迟于1952年末之前，苏联将中长路的一切权利及一切财产无偿移交中国，苏军从旅顺口撤出，大连行政完全由中国政府管辖，苏方临时代管或租用的财产，应由中国政府接收。至此，可以说中国已经完全挣脱了百年之久的不平等条约的束缚。

A mother isdevastated, crying, yelling all she can in that dark corner. There was nobody tohear her yell and not a soul to calm her, because outside her house is a long winding lonely road.The wind was at rest and the leaves didn't rustle, silence filling the air. Loneliness was alreadykilling her, but no one knows what made her cry?

Losing something you love with all your heart isn't really the pain you can ever overcome.Radha lost her baby, her only means to live. She saw her child getting killed and the accidentwas terrible. One lonely night, she was walking down the street to get a breath of fresh air withher child hugged tight in her arms.

The whole time she walked with her child in her arms, the only thing that worried her wasAryan's future. She was imagining and feeling every day of the child's growthand figuringwhat she would have in store for him. But who knows what's in store for us tomorrow, life canchange in a second.

On that deserted road, were a few streetlights barely enough? It was this one light that couldbe seen from a distance,but as it came closer it got brighter and brighter. That light changedRadha's life into darkness forever. A speeding car came down that road. The driver came with a full speed throwing beer bottles out of his half open window. He was definitely drunk,and the speed took, everything in its path. Just then, there was a loud cry, and silence set in again.

But the mother wasn't hurt. She opened her eyes, unable to focus her eyes, and didn't seeAryan. After a few minutes when her sight cleared up she looked all over in a panic for her baby,but alas! ... The child hadn't even seen life.
