国家司法考试卷一(经济法)模拟试卷13(题后含答案及解析)

国家司法考试卷一(经济法)模拟试卷13(题后含答案及解析)题型有:1. 单项选择题 2. 多项选择题 3. 不定项选择题单项选择题每题所给的选项中只有一个正确答案。
本部分1-50题,每题1分,共50分。
1.红星超市发现其经营的“荷叶牌”速冻水饺不符合食品安全标准,拟采取的下列哪一措施是错误的?(2013年试卷一第28题)A.立即停止经营该品牌水饺B.通知该品牌水饺生产商和消费者C.召回已销售的该品牌水饺D.记录停止经营和通知情况正确答案:C解析:本题考查食品召回制度。
①《食品安全法》采取“主动”与“强制”相结合的食品召回制度。
要求企业发现缺陷食品后主动召回,或者在企业不能承担应尽的社会责任时,应由政府监管部门出面“责令召回”。
②食品召回主体:(1)生产者;(2)县级以上质量监督、工商行政管理、食品药品监督管理部门可以责令召回;(3)食品经营者不是召回主体。
本题中,“红星超市”是食品经营者,并非速冻水饺的生产者,所以其无召回的义务。
③本法第53条规定了食品召回制度。
即第53条:“国家建立食品召回制度。
食品生产者发现其生产的食品不符合食品安全标准,应当立即停止生产,召回已经上市销售的食品,通知相关生产经营者和消费者,并记录召回和通知情况。
食品经营者发现其经营的食品不符合食品安全标准,应当立即停止经营,通知相关生产经营者和消费者,并记录停止经营和通知情况。
食品生产者认为应当召回的,应当立即召回。
食品生产者应当对召回的食品采取补救、无害化处理、销毁等措施,并将食品召回和处理情况向县级以上质量监督部门报告。
食品生产经营者未依照本条规定召回或者停止经营不符合食品安全标准的食品的,县级以上质量监督、工商行政管理、食品药品监督管理部门可以责令其召回或者停止经营。
”知识模块:食品安全法2.关于食品添加剂管制,下列哪一说法符合《食品安全法》的规定?(2011年试卷一第28题)A.向食品生产者供应新型食品添加剂的,必须持有省级卫生行政部门发放的特别许可证B.未获得食品添加剂销售许可的企业,不得销售含有食品添加剂的食品C.生产含有食品添加剂的食品的,必须给产品包装加上载有“食品添加剂”字样的标签D.销售含有食品添加剂的食品的,必须在销售场所设置载明“食品添加剂”字样的专柜正确答案:C解析:本题考查食品添加剂的相关规定。

2013高考仿真模拟13

2013高考仿真模拟(13)理综化学部分满分 100分第Ⅰ卷(选择题共42分)一、选择题(本大题共7小题,每小题6分。
在每小题给出的四个选项中,只有一项是符合题目要求的)7.化学与人类生产、生活、社会可持续发展密切相关,下列说法正确的是A.“天宫一号”中使用的碳纤维,是一种新型有机高分子材料B.为改善食品的色、香、味并防止变质,可加入大量食品添加剂C.用CO2合成聚碳酸酯可降解塑料,实现“碳”的循环利用D.大量使用化肥和农药,以提高农作物产量答案:C解析:碳纤维是一种复合材料,A项错误;食品添加剂的使用必须严格按照标准规范加入,不能任意改变其用量,B项错误;大量使用化肥和农药,会对环境造成污染,D项错误。
8.下列化学用语的理解正确的是A.某离子结构示意图为:可以表示35Cl-,也可以表示37Cl-B.电子式为:可以表示羟基,也可以表示氢氧根离子C.比例模型为:可以表示甲烷分子,也可以表示四氯化碳分子D.结构简式(CH3)2CHOH:可以表示1–丙醇,也可以表示2–丙醇答案:A解析:35Cl-和37Cl-质量数不同,但核内质子数和核外电子数相同,A项正确;仅表示羟基,B项错误;C项中的比例模型表示甲烷分子,由于氯原子比碳原子半径大,故该模型不能表示四氯化碳分子;D 项表示2–丙醇。
9.燃烧下列混合气体,所产生的CO2的量一定小于燃烧相同质量的丙烯所产生的CO2的量的是A.丁烯、丙烯 B.乙炔、乙烯C.乙炔、丙烷D.乙烷、环丙烷(C3H6)答案:D解析:本题所求燃烧相同质量的混合烃所产生的二氧化碳的质量一定小于燃烧同质量的丙烯产生的二氧化碳的量,也就是求:等质量的烃中,碳元素的质量分数比丙烯中碳元素的质量分数小的烃。
由于烯烃中C和H原子个数之比为1:2,即碳元素的质量分数相同。
乙炔中碳元素的质量分数大于烯烃中的碳元素的质量分数,而烷烃中的碳元素的质量分数小于烯烃中的碳元素的质量分数,因此只有D选项符合题意。

But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Lisa felt weak and tired—maybe it hadn’t been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks.Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.But when he heard the scream, followed by someone yelling, “Oh, my God, she fell in!” Frank didn’t hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. “No! Not you! ”his girlfriend screamed after him.She was right to be alarmed. By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the grins and drag her away from the edge. That was where Lisa briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse.Lisa thought she’d been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn’t, and that was when she realized how much pain she was in.Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40一minute train ride downtown—just as he had been seconds after the rescue, which made her think about her reaction at the time. “I saw the train coming and I was thinking he was going to die,” she explained.Q26 : What was the most probable cause for Lisa’s weakness?(D)A. She had run a long way.B. She felt hot in the subway.C. She had done a 1ot of work.D. She had donated blood the night before.Q27 :How did Frank save Lisa?(A)A. By lifting her to the platform.B. By helping her rise to her feet.C. By pulling her along the ground.D. By dragging her away from the edge.Q28 : When did Lisa become conscious again?(B)A. When the train was leaving.B. After she was back on the platform.C. After the police and fire officials came.D. When a man was cleaning the blood from her head.Q29 : Why did Jennifer try to stop her boyfriend?(D)A. Because they would miss their train.B. Because he didn’t see the train coming.C. Because she was sure Lisa was hard to lift.D. Because she was afraid the train would kill him.4.It's only 4 hours flying time from Sydney, but a world away. What better place to rest than a country where the only place people hurry is on the football field and things are done in "Fiji time"?Viti Lev -- Great Fiji -- is the largest island. Here you'll find the capital Suva and the international airport at Nadi. Vatoa, on the other hand, is a tiny island in the farthest part of Hiji. Then there are 331 other islands, many of them with places to stay.With less than a million people living on islands, you'll never feel crowded. And with a climate that changes only for five degrees between seasons, there's never a bad time to come.From cities to villages, from mountains to beaches, from water sports to wooden artworks, Fiji can give you more adventures and special experiences than you could find almost any where in the world.Whenever you come, wherever you go, you're sure to see some unforgettable events. From war dances to religious songs. From market days to religious days. It's not just staged for tourists; it's still a part of everyday life in Fiji. And any one of us can enjoy Fiji's spirit by being part of the traditional sharing of yaqona — a drink made from the root of a Fiji plant.So why not join us for the experience of a lifetime?Q30 : Where is the international airport of Fiji? (D)A. In SuvaB. In SydneyC. On the island of VatoaD. On the island of Viti LevuQ31 : What does the text tell us about Fijian people? (B)A. They invented "Fiji time" for visitorsB. They stick to a traditional way of lifeC. They like to travel from place to placeD. They love taking adventures abroadQ32 : One of the things that make Fiji a tourist attraction is ___(B)_____.A. its comfortable hotelsB. its good weather all year roundC. its exciting football matchesD. its religious beliefs5.When I was a child,I often dreamed of the time when I could leave home and escape to the city.We lived on a farm and,in the winter especially,we were quite cut off from the outside world.As soon as I left school, I packed my bags and moved to the capital. However,I soon discovered that city life has its problems too.One big disadvantage is money—it costs so much to go out,not to mention basics like food and housing. Another disadvantage is pollution.I suffer from asthma(哮喘),and at times the air is so bad that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car,I seldom use it because of the traffic jams.One choice is to go by bicycle,but that can be quite dangerous.Of course there are advantages.First,there is so much to do in the city,whatever your tastes in culture or entertainment(娱乐活动).Besides,there are wonderful jobs and greater chances of moving to a more important job or position.Finally,if you like shopping,the variety of goods is very surprising—and,what is more,shops are often only a short walk away.Is life better then, in the city? Perhaps it is,when you are in your teens(十几岁)or twenties.However,as you get older,and especially if you have small children,the peace of the countryside may seem preferable. I certainly hope to move back there soon.Q33 : What was the writer always thinking about when he was a child? (C)A.Staying on the farm.B.Moving to the countryside.C.Leaving home for the city.D.Running away from the school.Q34 : Which of the following is true about the writer?(D)A.He is very old now.B.He is in good health.C.He prefers driving a car.D.He lives in the city now.Q35 : What does the speaker try to do in the passage ? (A)A.express his opinions about way of lifeB.describe his life in the countrysideC.show an interest in the outside worldD.persuade the reader to live in the cityThe concept of student that exchange between countries is not a new one .
