2010年4月，昆明市公安局通讯处女民警王晓湘和该市路南县公安局副局长王俊波双双被枪杀在一辆“昌河”微型车上。此案由昆明市公安局刑侦支队负责侦查。2010年7月
2日下午，晓湘的丈夫、昆明市公安局戒毒所民警杜培武以涉嫌故意杀人罪被刑事拘留。10只警犬对杜培武进行了43次现场气味鉴别，其中41次认定杜培武的气味与“昌河”车上的气味同一，证明杜培武在案发前后驾驶过该车；专家组从北京请来的“中国头号刑侦专家”，也认为杜的作案嫌疑不能排除；公安部专家还对杜进行了测谎试验，结论是杜应当知情或者参与作案。经侦查人员的连续审讯、拳打脚踢及其它非人道手段，杜培武承认了杀害王晓湘、王俊波的“犯罪事实”，并指认了“作案现场”。2011年2月5日，昆明市中级人民法院以故意杀人罪一审判处杜培武死刑立即执行。杜培武大呼冤枉，向高级法院上诉称，他是在刑讯逼供情况下才承认杀人事实的。云南省高级人民法院鉴于本案重要物证—杀人用的枪支没有下落，遂改判杜培武死刑缓期二年执行。同年11月，杜培武被送进云南省第一监狱服刑。
2012年6月，昆明市公安局破获一起特大杀人盗车团伙，案犯承认2010年杀害王晓湘、王俊波案是他们所为。于是，云南省高级法院公开宣告杜培武无罪。
问：
（1）本案没有目击证人，被告人杜培武承认自己杀人的口供属于什么类型的证据？口供之外的证据属于什么类型的证据？本案中，若要证明被告人杜培武犯罪，对于单纯任用口供之外的证据证明案件事实，这种证据任用应当遵循什么样的规则？
（2）本案之所以成为错案，其原因是什么？
（3）透视本案，你认为我国刑事诉讼法应当作哪些改革或改良？
参考答案
一、名词解释（每题6分，共计30分）
1．对抗制诉讼
答：对抗制诉讼，又称当事人主义诉讼，是指诉讼的发动、继续和发展主要依赖于当事人；诉讼过程由当事人主导，法官仅处于消极中立的裁判者地位；当事人要负责证据的调查、准备、提出和证据价值的陈述工作，法官不能在当事人指明的证据范围以外依职权主动收集证据。在当事人主义之下，诉讼实际上是一种竞技运动，也是当事人之间的一种比赛，法官只处于一种裁判者的角色。
2．诉讼参与人
答：诉讼参与人是指在刑事诉讼中除司法人员以外的享有一定的诉讼权利、负有一定的诉讼义务的人。根据《刑事诉讼法》第106条的规定，诉讼参与人包括当事人、法定代理人、诉讼代理人、辩护人、证人、鉴定人和翻译人员。上述诉讼参与人通过行使诉讼权利、承担诉讼义务，对刑事诉讼的进程和结局发挥着不同程度的影响和作用，保证诉讼活动得以顺利进行。
3．地区管辖
答：地区管辖是指同级人民法院之间在审判第一审刑事案件权限上的划分。根据法律的规定。
地区管辖的划分原则如下：（1）以犯罪地人民法院管辖为主，被告人居住地人民法院管辖为辅。犯罪地，一般指实施犯罪的一切必要行为的地点，具体包括犯罪行为预备地、犯罪行为实施地、犯罪结果发生地和销赃地等。（2）以最初受理的人民法院审判为主，主要犯罪地人民法院审判为辅。
4．死刑复核程序
答：死刑复核程序是指人民法院对判处死刑的案件进行复审核准所遵循的特别审判程序。其特点为：
①适用对象具有单一性，即该程序只适用于判处死刑的案件，包括判处死刑立即执行和判处死刑缓期二年执行的案件，而不适用于其他案件。
②对于死刑案件的不可缺失性，即必须经过核准程序。
③诉讼程序具有特定性，即它是死刑案件的终结程序。
④程序启动具有主动性，与其他审判程序必须遵循不告不理原则不同，死刑复核程序不需经告诉而自动启动。
⑤死刑核准权具有专属性，即最高人民法院对死刑案件、高级人民法院对死缓案件有核准权，而不是所有的人民法院均有核准权。
5．暂予监外执行
答：暂予监外执行是指对被判处有期徒刑、拘役的罪犯因出现某种法定特殊情形不宜在监内执行时，暂时将其放在监外交由公安机关执行的一种变通方法。它不仅变更了执行场所，而且变更了执行方式。
暂予监外执行的对象包括：被判处有期徒刑或者拘役的罪犯，有严重疾病需要保外就医的；怀孕或者正在哺乳自己婴儿的妇女；生活不能自理，适用暂予监外执行不致危害社会的。对被判处无期徒刑的罪犯，属于怀孕或者正在哺乳自己婴儿的妇女的，可以暂予监外执行。
二、简答题（每题10分，共计40分）
1．简述被害人在我国刑事诉讼程序中的权利。
答：（1）被害人的诉讼地位
被害人是指其人身、财产或其他权益遭受犯罪行为侵害的人。被害人具有独立的诉讼当事人地位。
①被害人作为遭受犯罪行为侵害的人，与案件结局有着直接的利害关系；
②被害人基于实现使被告人受到合法的报应这一要求，具有积极主动地参与诉讼过程、影响裁判结局的愿望；
③被害人作为诉讼当事人，与被告人居于大致相同的诉讼地位，也拥有许多与被告人相对应的诉讼权利，但是法律也对被害人的诉讼地位作出了一些限制；
④被害人尽管具有当事人的诉讼地位，但他一般也是了解案件事实的人，其陈述本身也是法定的证据来源之一。
（2）被害人在我国刑事诉讼程序中的权利
①被害人与其他当事人所共同享有的诉讼权利
a．对于审判人员、检察人员和侦查人员侵犯其诉讼权利和人身侮辱的行为，有权提出控告。
b．对于审判人员、检查人员、侦查人员以及鉴定人员、翻译人员、书记员有《刑事诉讼法》第28条和第29条所规定的情形之一的，有权申请他们回避；对驳回申请回避的决定，有权申请复议一次。
c．有权参加法庭调查，在法庭上就起诉书指控的犯罪进行陈述，可以向被告人发问；有权向证人发问和质证；有权辨认、鉴别物证，听取书面证言及其他证据文书，并就上述证据向法庭陈述意见；有权申请通知新的证人到庭，调取新的物证，申请重新鉴定和勘验。
d．有权参加法庭辩论，对证据和案件情况发表意见，并与公诉人、其他当事人、辩护人等相互辩论。
e．有权对已发生法律效力的判决、裁定，向人民法院或人民检察院提出申诉。
f．有权使用本民族语言文字进行诉讼。
②被害人享有的特有诉讼权利
a．有权自案件移送审查起诉之日起，委托诉讼代理人。
b．对于侵犯其人身、财产权利的犯罪事实或者犯罪嫌疑人，有权向公安机关、人民法院或人民检察院报案或者控告，要求有关机关立案。对于不立案的决定有权获知原因并可申请复议；对于公安机关应当立案侦查的案件而不立案侦查的，有权向人民检察院提出，由后者要求公安机关说明理由，并予以纠正。
c．对于人民检察院所作的不起诉决定，有权获得不起诉决定书，并向上一级人民检察院申诉，要求提起公诉；对于人民检察院维持不起诉决定的，有权向人民法院起诉；也可以不经申诉，直接向人民法院起诉。
d．被害人有证据证明对被告人侵犯自己人身、财产权利的行为应当依法追究刑事责任，而公安机关或者人民检察院不予追究被告人刑事责任的案件，被害人有权向人民法院提起自诉。
e．对地方各级人民法院第一审的判决不服的，有权请求人民检察院抗诉。
2．简述上诉不加刑原则。
答：（1）上诉不加刑原则的概念
上诉不加刑原则是指第二审人民法院审判被告人一方上诉的案件，不得以任何理由加重被告人刑罚的一项审判原则。
①上诉是被告人的合法权利，不论上诉理由是否得当，都不能以被告人不服判决或态度不好而在二审判决中加重原判刑罚。

考研英语段落排序题全真模拟练习一 Directions: The following paragraphs are given in a wrong order. For Questions 41-45, you are required to reorganize these paragraphs into a coherent article by choosing from the list A-E to fill in each numbered box. The first and the last paragraphs have been placed for you in Boxes. Mark your answers on ANSWER SHEET 1. [A] On the first Monday after the second Wednesday in December, the electors who have been chosen in November assemble in their respective state capitals to signal their preference. The future president and vice-president must receive at least 270 electoral votes, a majority of the total of 538, to win. Members of the electoral college have the moral, but not the legal, obligation to vote for the candidate who won the popular vote in their state. This moral imperative, plus the fact that electors are members of the same political party as the presidential candidate winning the popular vote, ensures that the outcome in the electoral college is a valid reflection of the popular vote in November. [B] It is even possible for someone to win the popular vote, yet lost the presidency to another candidate. How? It has to do with the electoral college. [C] The electoral college was created in response to a problem encountered during the Constitutional Convention of 1787, where delegates were trying to determine the best way to choose the president. The framers of the Constitution intended that the electors, a body of men chosen for their wisdom, should come together and choose on behalf of the people. In fact, the swift rise of political parties guaranteed that the electoral of the people. In fact, the swift rise of political guaranteed that the electoral system never worked as the framers had intended; instead, national parties, i. e. nationwide alliances of local interests, quickly came to dominate the election campaigns. The electors became mere figureheads representing the state branches of the parties who got them chosen, and their votes were predetermined and predictable. [D] How are the electors chosen? Although there is some variation among states in how electors are appointed, generally they are chosen by the popular vote, always on the first Tuesday after the first Monday in November. Each political party in a state chooses a state of local worthies to be members of the electoral college if the party’s presidential candidate wins at least a plurality of the popular vote in the state. [E] How is the number of electors decided? Every state has one elector for each senator and representative it sends to Congress. States with greater populations therefore have more electors in the electoral college. All states have at least 3 electors, but California, the most populous state, has 54. The District of Columbia, though not a state, is also allowed to send three electors.

However, of the people who immediately 1 to mind when one thinks of entrepreneurs——Bill Gates, Richard Branson or Oprah Winfrey, for example—few have done more than 2 a speech at a business school. 3 , a recent study by King's College in London has suggested what many intuitively 4 : that entrepreneurship may actually be in the blood—more to do with genes than classroom experience. All of which 5 the question—does an entrepreneur really need a business-school education? Not surprisingly some of the best-known schools in the field have a 6 answer to this: they don't actually profess to create entrepreneurs, 7 they nurture innate ability. Or as Timothy Faley of the entrepreneurial institute at Michigan's Ross School of Business 8 it: “A good idea is not enough. You need to know how to 9 a good idea into a good business.” Schools do this in a number of ways. One is to 10 that faculty are a mix of classic academics and businesspeople with experience of 11 their own successful firms. They can also create “incubators” where students 12 ideas and rub shoulders on a day-to-day basis with the external business world, receiving both advice and hard cash in the form of investment. Arguably such help is now more important than ever. The modern entrepreneur is faced with a more 13 world than when Richard Branson began by selling records out of a phone box. According to Patrice Houdayer, head of one of Europe's best-known entrepreneurship schools, EMIYON in France, new businesses used to move through a 14 series of growth steps—what he terms garage, local, national and international. Now however, 15 the communications revolution, they can leapfrog these stages and go global more or less straightaway—encountering a whole new 16 of problems and challenges. In this 17 Professor Houdayer maintains that the increasingly 18 nature of MBA classes can help the nascent entrepreneur in three ways: by plugging them into an international network of contacts and advisors, by preparing them for the pitfalls and opportunities 19 with dealing across different cultures and by 20 them to the different ways that business is conducted around the globe.

(10 points) Facebook has been 1 with fire and has got its fingers burned, again. On November 29th America’s Federal Trade Commission (FTC) announced that it had reached a 2 settlement with the giant social network over 3 that it had misled people about its use of their personal data. The details of the settlement make clear that Facebook, which 4 over 800m users, betrayed its users’ trust. It is also notable because it appears to be part of a broader 5 by the FTC to craft a new privacy framework to deal with the rapid 6 of social networks in America. The regulator’s findin gs come at a 7 moment for Facebook, which is said to be preparing for an initial public offering next year that could value it at around $100 billion. To 8 the way for its listing, the firm first needs to resolve its privacy 9 with regulators in America and Europe. 10 its willingness to negotiate the settlement 11 this week. Announcing the agreement, the FTC said it had found a number of cases where Facebook had made claims that were “unfair and deceptive, and 12 federal law”. For instance, it 13 personally identifiable information to advertisers, and it failed to keep a promise to make photos and videos on deleted accounts 14 . The settlement does not 15 an admission by Facebook that it has broken the law, but it deeply 16 the company nonetheless. In a blog post published the same day, Mark Zuckerberg, Facebook’s boss, tried to17 the impact of the deal. First he claimed that “a small number of high-profile mistakes” were 18 the social network’s “good history” on privac y. The FTC is not relying on Facebook to police itself. Among other things, the company will now have to seek consumers’ approval before it changes the way it shares their data. And it has agreed to an independent privacy audit every two years for the next 20 years. There is a clear pattern here. In separate cases over the past couple of years the FTC has insisted that Twitter and Google accept regular 19 audits, too, after each firm was accused of violating its customers’ privacy. The intent seems to be to create a regulatory regime that is tighter than the status quo, 20 one that still gives social networks plenty of room to innovate. 1.
