8 阅读理解。 Nikkli was brought up from a vey early age by her father while her sister was raised by her mother. Nikki spent a very small amount of time with her mum and sister when she was about 6 years old, but soon after contact stopped when communication broke down between her parents. She never felt she wanted to find her family while she was growing up. But now with a husband and a son, she decided it was the right time. Nikki didn"t know where to start, but her husband"s mum had used 192. com for finding people before and recommended it to her. With the help of her son, she started by searching for her sister"s full name on the electoral roll (选民登记册) without a location, because she had no idea where she lived, even her date of birth. From that one search, the site returned two results listed in the area they used to live. Nikki decided to call the first number. To her absolute surprise, it was her long lost sister! So after 20 years, it was one phone call that helped her contact her sister! Her sister then passed her number on to her mother, who called Nikki straight away, and it was like they had never been apart. Her mum was so glad to find out Nikki was well that they arranged to meet everyone that Saturday (3 days after the phone call) where she was reunited with her sister and met her two nephews for the first time. Nikki also found out she had a half (同父异母的) sister and brother. When talking about the reunion, Nikki said, "192.com made finding my long lost family very easy. I was not on any social networking sites before and surprisingly neither was my sister or mum, so we would never have found each other that way." Nikki will be spending her first Christmas tighter with the other side of her family this year. 1. What did Nikki know about her sister before her searching? A. Her address. B. Her birthday. C. Her name. D. Her telephone number. 2. It can be inferred from Paragraph 4 that _________. A. Nikki"s mum has a bad memory now B. Nikki is about 26 years old now C. Nikki"s sister lives with her mum together D. Nikki dialed another phone number to contact her mum 3. What can we learn about Nikki from the passage? A. She knows much about the Internet. B. Her sister has not got married so far. C. Her mum got birth to four children in all. D. She got in touch with her mum on Monday. 4. All of the following made contributions to Nikki"s reunion with her family EXCEPT _______. A. her father B. 192.com C. her son D. her mother-in-law 5. The text is mainly about _______. A. how to find a family member B. a wonderful Christmas C. how important the electoral roll is D. a family reunion thanks to 192.com

10 在光滑的水平桌面上有等大的质量分别为M="0.6" kg，m="0.2" kg的两个小球，中间夹着一个被压缩的具有E p="10.8" J弹性势能的轻弹簧（弹簧与两球不相连），原来处于静止状态.现突然释放弹簧，球m脱离弹簧后滑向与水平面相切、半径为R="0.425" m的竖直放置的光滑半圆形轨道，如图所示.g取10 m/s 2.则下列说法正确的是： A．球m从轨道底端A运动到顶端B的过程中所受合外力冲量大小为3.4 N·s B．M离开轻弹簧时获得的速度为9m/s C．若半圆轨道半径可调，则球m从B点飞出后落在水平桌面上的水平距离随轨道半径的增大而减小 D．弹簧弹开过程，弹力对m的冲量大小为1.8 N·s
