四、翻译(英译汉)
　　51.But these beliefs about peptide hormones(肽激素)were questioned as laboratory after laboratory found that antiserums(抗血清)to peptide hormones, when injected into the brain, bind in places other than the hypothalamus(下丘脑), indicating that either the hormones or substances that cross-react with the antiserums are present.
　　答案：但是这些对于肽激素的信仿，被一个又一个的实验室质疑，他们发现抗血清被注入大脑后，并不在下丘脑那里才凝固，显示出肽激素和与抗血清反作用的物质都不存在。
　　五、写作

　　1. 盗版软件比比皆是
　　2. 盗版软件猖獗的原因
　　3. 如何打击盗版软件
　　答案：
　　It’s Time to Stop Software Piracy
　　China has often been criticized for the rampant practice of software piracy. Take a look around. We operate on pirated Windows systems, defend PC security with pirated Kaspersky anti-virus programmes, process files with pirated Microsoft Office, draft 3D designs with pirated AutoCAD, refine pictures with pirated Adobe
　　Photoshop, and study English with pirated Kingsoft’s electronic dictionaries and translators. It’s no exaggeration that pirated software is everywhere.
　　The logic behind the phenomenon is simple and clear: if a pirated copy is available for just a tiny fraction of the normal price, not to speak of many of the free downloads online, who would pay for an authentic copy? Cheaper prices aside, easy access is another important factor. With such a large gathering of pirated upgrades around, who would bother to spend time and money searching the stores for an authorized yet outdated version?
　　Despite these apparent benefits, the practice of software piracy should be banned, because it represents unfair competition and by nature it’s a no-win situation. But how? Two approaches are to be taken at the same time: Technically, software developers should enhance their antipiracy engineering, so that cracking the software should be virtually impossible. And legally, the government should also tighten its antipiracy laws and toughen up the penalties, so that violations should be costly.
