Section I Use of English Directions: Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D on the ANSWER SHEET. (10 points) Weighing yourself regularly is a wonderful way to stay aware of any significant weight fluctuations. 1 , when done too often, this habit can sometimes hurt more than it 2 . As for me, weighing myself every day caused me to shift my focus from being generally healthy and physically active to focusing 3 on the scale. That was bad to my overall fitness goals. I had gained weight in the form of muscle mass, but thinking only of 4 the number on the scale, I altered my training program. That conflicted with how I needed to train to 5 my goals. I also found that weighing myself daily did not provide an accurate 6 of the hard work and progress I was making in the gym. It takes about three weeks to a month to notice any significant changes in your weight 7 altering your training program. The most 8 changes will be observed in skill level, strength and inches lost. For these 9 , I stopped weighing myself every day and switched to a bimonthly weighing schedule 10 . Since weight loss is not my goal, it is less important for me to 11 my weight each week. Weighing every other week allows me to observe and 12 any significant weight changes. That tells me whether I need to 13 my training program. I use my bimonthly weigh-in 14 to get information about my nutrition as well. If my training intensity remains the same, but I’m constantly 15 and dropping weight, this is a 16 that I need to increase my daily caloric intake. The 17 to stop weighing myself every day has done wonders for my overall health, fitness and well-being. I’m experiencing increased zeal for working out since I no longer carry the burden of a 18 morning weigh-in. I’ve also experienced greater success in achieving my specific fitness goals, 19 I’m trai ning according to those goals, not the numbers on a scale. Rather than 20 over the scale, turn your focus to how you look,

高考真题集训 1.(2018·北京高考)关于分子动理论,下列说法正确的是( ) A.气体扩散的快慢与温度无关 B.布朗运动是液体分子的无规则运动 C.分子间同时存在着引力和斥力 D.分子间的引力总是随分子间距增大而增大 答案 C 解析扩散的快慢与温度有关,温度越高,扩散越快,故A错误;布朗运动为悬浮在液体中固体小颗粒的运动,不是液体分子的热运动,固体小颗粒运动的无规则性,是液体分子运动的无规则性的间接反映,故B错误;分子间斥力与引力是同时存在,而分子力是斥力与引力的合力,分子间的引力和斥力都是随分子间距增大而减小;当分子间距小于平衡位置时,表现为斥力,即引力小于斥力,而分子间距大于平衡位置时,表现为引力,即斥力小于引力,但总是同时存在的,故C正确,D错误。 2.(2019·北京高考)下列说法正确的是( ) A.温度标志着物体内大量分子热运动的剧烈程度 B.内能是物体中所有分子热运动所具有的动能的总和 C.气体压强仅与气体分子的平均动能有关 D.气体膨胀对外做功且温度降低,分子的平均动能可能不变 答案 A 解析温度是分子平均动能的量度(标志),分子平均动能越大,分子热运动越剧烈,A 正确;内能是物体内所有分子的分子动能和分子势能的总和,B错误;气体压强不仅与气体分子的平均动能有关,还与气体分子的密集程度有关,C错误;温度降低,则分子的平均动能变小,D错误。 3.(2017·北京高考)以下关于热运动的说法正确的是( ) A.水流速度越大,水分子的热运动越剧烈 B.水凝结成冰后,水分子的热运动停止 C.水的温度越高,水分子的热运动越剧烈 D.水的温度升高,每一个水分子的运动速率都会增大 答案 C 解析分子热运动的剧烈程度由温度决定,温度越高,热运动越剧烈,与物体的机械运动无关,A错误,C正确。水凝结成冰后,温度降低,水分子热运动的剧烈程度减小,但不会停止,B错误。水的温度升高,水分子运动的平均速率增大,但并不是每一个水分子的运动速率都增大,D错误。 4.(2019·全国卷Ⅰ)(1)某容器中的空气被光滑活塞封住,容器和活塞绝热性能良好,空气可视为理想气体。初始时容器中空气的温度与外界相同,压强大于外界。现使活塞缓慢移动,直至容器中的空气压强与外界相同。此时,容器中空气的温度________(填“高于”“低于”或“等于”)外界温度,容器中空气的密度________(填“大于”“小于”或“等于”)外界空气的密度。 (2)热等静压设备广泛应用于材料加工中。该设备工作时,先在室温下把惰性气体用压缩

考研英语二历年真题及答案

2002 Directions:Translate the following passage into Chinese and put your translation on the ANSWER SHEET. Since 1981,farmers in Holland have been encouraged to adopt“green”farming techniques that were thought to benefit plant and bird life.Farmers who have voluntarily adopted these measures are compensated by the European Union.The goal of the program is to work against the negative effects of modem fanning,such as declines in species diversity and the disturbance of local nesting grounds.The“green”methods of farming cost the European Union about 1.7 billion Euros annually.This is about 4 percent of the budget for“Common Agricultural Policy,”and the compensation is expected to rise to 10 percent within the next few years. Various forms of“green farming”employed around the world have proved successful, and all new methods thought to be environmentally sensitive should be subject to sound scientific evaluation to determine whether they are actually meeting the intended goals. Part V Writing(30 minutes,15 points) Directions:You are to write in no less than 120 words about the title “What I Consider Important in Life”.Your composition should be based on the Chinese outline given below.

解析:选B根据质量数和电荷数守恒可知四个核反应方程分别为147N+24 He→178O+11H、1327Al+24He→1530P+01n、115B+11H→48Be+24He、36Li+11H→23He+24He,故只有B项正确. 4.(江苏卷)已知A和B两种放射性元素的半衰期分别为T和2T,则相同质量的A和B经过2T后,剩有的A和B质量之比为() A.1∶4 B.1∶2 C.2∶1 D.4∶1 解析:选B经过2T,对A来说是2个半衰期,A的质量还剩1 4.经过2T, 对B来说是1个半衰期,B的质量还剩1 2.所以剩有的A和B质量之比为1∶2, 选项B正确. 5.(全国卷Ⅱ)一静止的铀核放出一个α粒子衰变成钍核,衰变方程为238 92U→90234 Th+24He.下列说法正确的是() A.衰变后钍核的动能等于α粒子的动能 B.衰变后钍核的动量大小等于α粒子的动量大小 C.铀核的半衰期等于其放出一个α粒子所经历的时间 D.衰变后α粒子与钍核的质量之和等于衰变前铀核的质量 解析:选B根据动量守恒定律可知衰变后钍核的动量大小等于α粒子的动 量大小,B正确;根据E k=p2 2m可知衰变后钍核的动能小于α粒子的动能,A错误;半衰期是指放射性元素的原子核有半数发生衰变所需时间,C错误;衰变后质量亏损,因此α粒子与钍核的质量之和小于衰变前铀核的质量,D错误.6.(全国卷Ⅰ)大科学工程“人造太阳”主要是将氘核聚变反应释放的能量用来发电.氘核聚变反应方程是12H+12H→23He+01n.已知21H的质量为2.013 6 u,23He 的质量为3.015 0 u,01n的质量为1.008 7 u,1 u=931 MeV/c2.氘核聚变反应中释放的核能约为() A.3.7 MeV B.3.3 MeV C.2.7 MeV D.0.93 MeV 解析:选B氘核聚变反应的质量亏损Δm=2m 氘-m 氦 -m n=0.003 5 u,则 该反应释放的核能为ΔE=Δm×931 MeV=3.258 5 MeV≈3.3 MeV.
