When I married, I was twenty-two years old, and my husband was thirty then. Now he is sixty, I know, and that is twice thirty. And so I am twice twenty-two. That is forty-four, isn't it?”( ) 1.

Mary should be _______.A.forty-fourB. forty-fiveC. fiftyD. fifty-twoBExpert(专家) say that students usually need eight to ten hours’sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us tat every morning her 10-year-old boy put up one finger (手指)with his eyes still closed, begging(请求) for one more minute to sleep. Like thousands of students “early birds”in China, he has to get up before six every morning.A report shows that without a good night’s sleep, students seem to be weaker (虚弱)than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.Experts have ever said that the students should develop good study habits. So some clever students never study last, they are able to work well in class.( ) 6.

初二物理下册第一二单元练习题
初二物理下册第一二单元练习题在初二物理下册的第一二单元中，我们学习了很多有关运动的知识，通过练习题的形式巩固了所学的内容。
本文将整理出一些较为典型的练习题，分析解答方法，以帮助同学们更好地理解和掌握这些知识点。
题目1：一辆火车以20m/s的速度匀速行驶了15秒，求火车在这段时间内所走的路程。
解答：题目给出了火车的速度和时间，要求求解路程。
根据运动学中的公式：路程=速度×时间，代入已知条件，即可得出答案。
答案：路程 = 20 m/s × 15 s = 300 m题目2：一个物体的速度随时间的变化关系如下表所示，求物体在5秒内所走的路程。
时间（s） 0 1 2 3 4 5速度（m/s） 0 2 4 6 8 10解答：题目给出了速度随时间的变化关系，要求求解物体在5秒内所走的路程。
由于速度在每个时间点上的数据是离散的，我们可以通过近似法来计算总路程。
首先，我们计算出每段时间内的平均速度：第1秒到第2秒的平均速度 = （0 m/s + 2 m/s）/ 2 = 1 m/s第2秒到第3秒的平均速度 = （2 m/s + 4 m/s）/ 2 = 3 m/s第3秒到第4秒的平均速度 = （4 m/s + 6 m/s）/ 2 = 5 m/s第4秒到第5秒的平均速度 = （6 m/s + 8 m/s）/ 2 = 7 m/s然后，我们可以使用近似法计算总路程，即将每段时间内的平均速度与时间相乘，再相加：总路程 = （1 m/s × 1 s）+（3 m/s × 1 s）+（5 m/s × 1 s）+（7 m/s ×1 s）+（10 m/s × 1 s）= 1 m + 3 m + 5 m + 7 m + 10 m= 26 m答案：物体在5秒内所走的路程为26米。
题目3：一辆汽车加速度为2m/s²，从静止开始加速，经过10秒的时间，汽车的速度为多少？解答：题目给出了汽车的加速度和时间，要求求解汽车的速度。
