Text3 In the past several years,as the nascent medium of virtual reality has come into its own,scientists and creators have begun to explore its potential effects on the human mind.Some are undoubtedly positive-as,for instance,when the technology is used to help war veterans overcome posttraumatic stress disorder,or as a means to expand a person's capacity for compassion.But the immediacy of virtual reality has a dark side,too.Several months ago,Michael Madary and Thomas K.Metzinger,researchers from the Johannes Gutenberg University of Mainz,in Germany,published a series of recommendations on the ethical design and implementation of virtual reality.Their appraisal of the medium's psychological force is both studious and foreboding."The power of virtual reality to induce particular kinds of emotions could be used deliberately to cause suffering,"they write."Conceivably,the suffering could be so extreme as to be considered torture."In filmmaking,the director must perform a kind of seduction of dread,leading viewers through an escalating series of psychological states.In the immersive world of virtual reality,no such dance is required.Part of the power of virtual reality-based horror comes from the fact that the director knows exactly where the viewer is looking."With that knowledge,we can play mind tricks or trigger events based on the gaze,"Jon Hibbins,the director of Psytec Games,a London-based virtual reality studio,said.For instance,he said,in Psytec's most recent fantasy-horror title,Crystal RiR,"a monster can appear in a vent only when the player looks at the vent."Hibbins claims that,as viewers'brains are tricked into believing that they are physically present in a reality,the memories they form are much stronger than those made when watching so-called flat-screen media.To soften these memories,Hibbins and his team have introduced a slider into their game that allows players to control the intensity of the horror."'Normal'will be an average scare experience,"he said."You'Il hear voices in the distance,ghosts in the corridors,sound from the voids,and snakes in the corridors.'Extreme'introduces jump scares,such as ghost figures that run through your body.It really does offer everyone an option."Stephan said,"Long-term,perhaps it's a case of building literacy in players and viewers so they understand when the scares are coming.For now,I think that means taking it slow."35.Which of the following would be the best title ofthe text?

A.The Dark Side ofVirtual Reality
B.The Coming Horror ofVirtual Reality
C.Ways to Slow down Horror in Virtual Reality
D.Virtual Reality's Contribution to Games

答案：B
解析：
主旨大意题。本题询问的是最佳标题，文章主要描写的是虚拟现实带来的恐惧，故B项是最佳标题。【干扰排除】文巾除了谈论虚拟现实的黑暗面，也提到了它的一些积极作用，故A项错误；C项“减缓恐怖的方法”在文中虽有所提及，但不是文中主要表达的内容，故排除；D项“虚拟现实对游戏的贡献”也只是文中捉及的一方面，其还有黑暗的一面，不能概括文章的主旨，故排除。

第5题：

Prior to the UML, there was no clear leading(66)language. Users had to choose from among many similar modeling languages with minor differences in overall(67)power. Most of the modeling languages shared a set of commonly accepted concepts that are expressed slightly differently in various languages. This lack of(68)discouraged new users from entering the OO market and from doing OO modeling, without greatly expanding the power of modeling. Users longed for the industry to adopt one, or a very few, broadly supported modeling languages suitable for(69)usage.

Some Vendors were discouraged from entering the OO modeling area because of the need to support many similar, but slightly different, modeling languages. In particular, the supply of add on tools has been depressed because small vendors cannot afford to support many different formats from many different(70)modeling tools. It is important to the entire OO industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.

A．programming

B．modeling

C．formal

D．intelligent

For nearly ten years, the Unified Modeling Language (UML) has been the industry standard for visualizing, specifying, constructing, and documenting the(71) of a software-intensive system. As the(72) standard modeling language, the UML facilitates communication and reduces confusion among project(73) . The recent standardization of UML 2.0 has further extended the language's scope and viability. Its inherent expressiveness allows users to(74) everything from enterprise information systems and distributed Web-based applications to real-time embedded systems.

The UML is not limited to modeling software. In fact, it is expressive enough to model(75) systems, such as workflow in the legal system, the structure and behavior. of a patient healthcare system, software engineering in aircraft combat systems, and the design of hardware.

To understand the UML, you need to form. a conceptual model of the language, and this requires learning three major elements: the UML's basic building blocks, the rules that dictate how those building blocks may be put together, and some common mechanisms that apply throughout the UML.

A．classes

B．components

C．sequences

D．artifacts

解析：近十年来，统一建模语言(uML)已经成为工业标准，它可用来可视化、规范化说明、构建以及文档化软件密集系统中的开发制品。作为事实上的工业标准，UML能够方便项目相关人员的沟通并减少理解上的二义问题。uML 2．0标准扩宽了该语言的应用范围，它所具有的表达能力能够让用户对企业信息系统、分布式Web系统和嵌入式实时系统进行建模。uML不仅能够对软件系统进行建模，实际上，它具有足够的能力去对法律系统中的工作流、病人监护系统中的结构和行为、飞行战斗系统和硬件系统进行建模。为了理解UML，需要具备该语言的概念模型，这需要学习三个主要元素：uML的基本构造块，基本构造块的关系规则和应用这些构造块与规则的通用机制。
