刑法总论一、单项选择题1.下列哪种说法是正确的?(A.将强制猥亵妇女罪中的“妇女”解释为包括男性在内的人,属于扩大解释B.将故意杀人罪中的“人”解释为“精神正常的人”,属于应当禁止的类推解释C.将伪造货币罪中的“伪造”解释为包括变造货币,属于法律允许的类推解释D.将为境外窃取、刺探、收买、非法提供国家秘密、情报罪中的“情报”解释为“关系国家安全和利益、尚未公开或者依照有关规定不应公开的事项”,属于缩小解释2.关于罪刑法定原则,下列哪一选项是正确的?(A.罪刑法定原则的思想基础之一是民主主义,而习惯最能反映民意,所以,将习惯作为刑法的渊源并不违反罪刑法定原则B.罪刑法定原则中的“法”不仅包括国家立法机关制定的法,而且包括国家最高行政机关制定的法C.罪刑法定原则禁止不利于行为人的溯及既往,但允许有利于行为人的溯及既往D.刑法分则的部分条文对犯罪的状况不作具体描述,只是表述该罪的罪名。
这种立法体例违反罪刑法定原则3.关于因果关系,下列哪一选项是错误的?(A.甲故意伤害乙并致其重伤,乙被送到医院救治。
当晚,医院发生火灾,乙被烧死。
甲的伤害行为与乙的死亡之间不存在因果关系B.甲以杀人故意对乙实施暴力,造成乙重伤休克。
甲以为乙已经死亡,为隐匿罪迹,将乙扔入湖中,导致乙溺水而亡。
甲的杀人行为与乙的死亡之间存在因果关系C.甲因琐事与乙发生争执,向乙的胸部猛推一把,导致乙心脏病发作,救治无效而死亡。
甲的行为与乙的死亡之间存在因果关系,是否承担刑事责任则应视甲主观上有无罪过而定D.甲与乙都对丙有仇,甲见乙向丙的食物中投放了5毫克毒物,且知道5毫克毒物不能致丙死亡,遂在乙不知情的情况下又添加了5毫克毒物,丙吃下食物后死亡。
甲投放的5毫克毒物本身不足以致丙死亡,故甲的投毒行为与丙的死亡之间不存在因果关系4.卡车司机甲在行车途中,被一吉普车超过,甲顿生不快,便加速超过该车。
不一会儿,该车又超过了甲,甲又加速超过该车。
当该车再一次试图超车行至甲车左侧时,甲对坐在副座的乙说,“我要吓他一下,看他还敢超我。

Well ,if you are tired of all this, then read on for what to do to have happier holidays.[21 Make your expectations possible to achieve. If you want everything to be perfect, with dinner starting on time. and all the kids behaving. you' re probably setting yourself up for disappointment. The thing to do is lower your expectations and give yourself permission not to have perfection.[3] Tell them that you want this year to be an event where everybody leaves the table and the house feeling good about himself or herself. At the McGraw house, we have a family Thanksgiving celebration ,where, before we eat, we make it clear that this day is important, in which we stop our usual routines and focus merely on celebrating the lives we've all been given.[4] Also remember that the holidays are not time for problem-solving. They are not annual events tosolveyourproblems. If your family conflicts are worth talking about in December ,trust me ,they will still be "hot" in February .so save them until then. Remember , instead, what the holidays are really about -- family togetherness with those who arc an important part of your lives.[5] Give to others. If you're feeling empty during the holidays, the best way to get is to give. Fill up your heart by helping those who are less fortunate, for example. You will be amazed at the outcome ![6J Finally ,if all else fails and your family is still getting on your nerves, take a step back and relax. Keep smiling, no matter what happens, and try to remember, " There's always next year. "61. What's the text mainly about? ( no more than 10 words)_____________________________________________________________________ 62. Complete the following sentence with a proper word according to Paragraph 2.A person who wants everything about a holiday to be perfect will be likely to feel ______'63.
