3 阅读理解。 When I was small and my grandmother died, I couldn"t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying. Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to study found that 85 percent of women and 73 percent of men report feeling better after crying. Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don"t even know we" re very sad until we cry. We learn about our emotions through Crying, and then we can deal with them. Just as crying can be healthy, not crying - holding back tears of anger, pain or suffering - can be bad for physical (身体的) health, Studies have shown that too much control of emotions can lead to high blood pre ssure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don"t fight it. It"s a natural -and healthy-emotional response (反应). 1.

7 阅读理解。 Charlie studied in a famous college for four years. He studied hard and did well in all his subjects. He hoped to become a good teacher. This year he left the college and began to work in a middle school. He likes his students and is strict (严格的) with them. He does his best to make his classes lively and interesting. One day he carefully explained a chemical reaction (反应) to the students of Grade 2 in the chemistry lab. "Be careful, everyone," he said loudly. "Before I make the experiment,there"re twenty five atoms of carbon (碳原子),but after I finish it, there"re twenty four atoms of carbon left!" He stopped to watch the classroom and hoped his students would go on explaining it. But the young men looked at each other and nobody answered him. He had to ask, "What happens? What makes the atom lost?" The classroom was very quiet and none of the students looked at their teacher. "Who can tell us where it has gone?" Suddenly a soft voice came from the back row, "We did not see anybody leave the lab!" 1.Charlie began to work in the middle school because ___. A. he had been in the school for four years B. he couldn"t do anything except teaching C. he hoped to become a good teacher D. he did well in all his subjects 2.Charlie hopes____, so he does his best to make his classes lively and interesting. A. all his students could understand him B. his students wouldn"t be afraid of him C. his students carefully watched him making the experiment D. his students could do well in chemistry 3.That day Charlie wished ____ . A. his students could learn the chemical reaction B. his students could find the atom of carbon C. his students could count(数) the atoms of carbon D. his students could make the experiment 4. The students couldn"t answer Charlie"s questions because _____ . A. none of them had seen the atoms B. they didn"t understand their teacher C. the chemical reaction was too complicated D. they all wanted to drop the subject 5.In fact, _____. A. Charlie failed that day B. the student in the back row didn"t watch her teacher carefully C. the student in the back row hadn"t learned chemistry before D. Charlie failed in making the experiment
8 如图所示，在游乐节目中，选手需要借助悬挂在高处的绳飞越对面的高台上. 一质量m=60kg的选手脚穿轮滑鞋以v 0=7m/s的水平速度抓住竖直的绳开始摆动,选手可看作质点，这时，绳子的悬挂点到选手的距离L＝6m.当绳摆到与竖直方向夹角θ=37°时，选手放开绳子。不考虑空气阻力和绳的质量.取重力加速度g="10m/s2," sin370=0.6，cos370=0.8.求： (1)选手放开绳子时的速度大小； (2)选手放开绳子后继续运动到最高点时，刚好可以站到水平传送带A点，传送带始终以v 1=3m/s的速度匀速向左运动，传送带的另一端B点就是终点,且S AB=3.75m.若选手在传送带上不提供动力自由滑行，受到的摩擦阻力为自重的0.2倍,通过计算说明该选手是否能顺利冲过终点B，并求出选手在传送带上滑行过程中因摩擦而产生的热量Q。
