2.可适当增加细节，以使行文连贯。
第二节读后续写（满分25分）
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Over the summer I moved from Texas to Missouri. I was really nervous about starting a new school. I decided that I would be much happier in a new school if I made friends that were so-called “popular” . Getting in with the right group of people would make my life a whole lot better. I bought a new outfit（服装）, expecting the first day would be perfect.
On the first day of school, scared, yet eager to begin my new life, I walked up the stairs. My first class was geometry（几何学）, but where was it I was standing in the hall looking confused, when a short, blond girl wearing glasses came up and asked,“Are you new You look lost. Do you want me to help you find your class My name is Diane. What's yours ” Though she seemed a bit strange, definitely not the kind of person I wanted to be associated with, I decided to answer her anyway. I was, after all, lost. After exchanging names, I followed her up the stairs and down a hallway on the right. When we reached my room she said, “Well, here you are. It was nice meeting you. I hope I see you again and your day goes all right.” I said a quick thank-you and waved good-bye.
Once inside the classroom, I saw one big group of people huddled around（聚集） someone who seemed to be telling some sort of story. I walked over and got close enough to overhear. All eyes were glued to the guy in the middle of the circle. I decided that this guy was popular.
A few minutes later the teacher told everyone to find a seat and get ready for the class. I managed to get one right next to the guy. I said, “Hi, my name is April and I'm new here.” He said coldly, “Hi, I'm Johnny.” That class dragged on and on. Finally, the bell rang. I turned to him and asked, “I'm not sure where my next class is, could you help me find it ” He looked at me and then said a quick NO, turned back to his friends, and walked out of the classroom.

（3）两个小组使用完全相同的酒精灯加热，水的初始温度也相同，但绘制出的温度随时间变化图象（a、b）不同，表现为加热至沸腾的时间不一样。 根据知 ，在加热条件相同的情况下，两组实验中水的质量不同，质量大的水需要吸收更多热量才能沸腾，耗时更长。
（4）停止加热后，刚停止沸腾的水温度已略有下降。此时加入少量食盐，水重新沸腾，这表明加入食盐后，水的沸点有所降低，使得水温能再次达到沸点并沸腾。
综上所述，（1）第一空答案为：水银；（2）第一空答案为：高；（3）第一空答案为：质量；（4）第一空答案为：降低
【分析】本实验为探究水的沸腾实验，涉及温度计的选择、实验操作规范、实验现象差异原因及沸点变化等知识点。
（1）考查温度计的选择依据。实验需测量水沸腾时的温度，水的沸点在标准大气压下为100℃。由表格数据可知，酒精的沸点为78℃，低于水的沸点，若选用酒精温度计，酒精会在水沸腾前就沸腾，无法准确测量水的沸点；而水银的沸点为357℃，高于水的沸点，能正常测量。
（2）考查温度计的正确使用及操作不当的影响。测量水温时，温度计的玻璃泡应完全浸没在被测液体中，且不能碰到容器底或容器壁。小明操作中玻璃泡碰到容器底部，由于酒精灯直接加热容器底，容器底温度高于水的实际温度，导致测出的水温偏高。
（3）考查实验现象差异的原因分析。两个小组使用相同酒精灯加热，水的初温相同，但加热至沸腾的时间不同。在加热装置相同、初温相同的情况下，水加热至沸腾的时间取决于水的质量，质量越大，需要吸收的热量越多，加热时间越长。
