What are the advantages of using cloud computing?答案：Cloud computing offers several advantages, including:- Cost savings: Companies can reduce their infrastructure costs by using cloud services instead of maintaining their own hardware.- Scalability: Cloud services can easily scale up or down based on demand, allowing businesses to only pay for what they need.- Flexibility: Users can access cloud services from anywhere with an internet connection, enabling remote work and collaboration.- Disaster recovery: Cloud providers often have backup systems in place, ensuring data can be recovered in case of a disaster.- Automatic updates: Cloud services are typically updated regularly by the provider, ensuring users have access to the latest features and security patches.2. Explain the difference between HTTP and HTTPS.答案：HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the internet. It is not secure, meaning that the data being transmitted can be intercepted and read by anyone. HTTPS (Hypertext Transfer Protocol Secure), on the other hand, is a secure version of HTTP. It uses encryption to ensure that data is encrypted before transmission, making it much more difficult for hackers to intercept and read. HTTPS is commonly used for secure online transactions, such as submitting credit card information or personal details.四、编程题请编写一个Python程序，实现计算圆的面积和周长的功能。

教材特点
复杂长句多
科技文章要求叙述准确，推理严谨，因此一句话里包 含三四个甚至五六个分句的，并非少见。译成汉语时，必 须按照汉语习惯破成适当数目的分句，才能条理清楚，避 免洋腔洋调。这种复杂长句居科技英语难点之首，要学会 运用语法分析方法来加以剖析，以便以短代长，化难为易。 例如： Factories will not buy machines unless they believe that the machine will produce goods that they are able to sell to consumers at a price that will cover all cost. 这是由一个主句和四个从句组成的复杂长句，只有进行 必要的语法分析，才能正确理解和翻译。现试译如下： 除非相信那些机器造出的产品卖给消费者的价格足够 支付所有成本，否则厂家是不会买那些机器的。 节译：要不相信那些机器造出的产品售价够本，厂家 是不会买的。

被动语态多 有三分之一以上用被动语态。例如： (a) No work can be done without energy. 译文：没有能量决不能做功。 (b) All business decisions must now be made in the light of the market. 译文：所有企业现在必须根据市场来作出决策。
教材特点
非谓语动词多
英语每个简单句中，只能用一个谓语动词，如果 读到几个动作，就必须选出主要动作当谓语，而将其 余动作用非谓语动词形式，才能符合英语语法要求。 非谓语动词有三种：动名词、分词（包括现在分 词和过去分词）和不定式。例如： 要成为一个名符其实的内行，需要学到老。 这句中，有“成为”、“需要”和“学”三个表 示动作的词，译成英语后为： To be a true professional requires lifelong learning. 可以看出，选好“需要”（require）作为谓语， 其余两个动作：“成为”用不定式形式 to be，而 “学”用动名词形式learning，这样才能符合英语语 法要求。
Computer Overview－ Introduction
Computers have opened up a new era in manufacturing through the techniques of automation, and they have enhanced modern communication systems. They are essential tools in almost every field of research and applied technology, from constructing models of the universe to producing tomorrow’s weather reports, and their use has in itself opened up new areas of conjecture. 计算机通过自动化技术开辟了制造业的新纪元，而 且它们也增强了现代通信系统的性能。在几乎每一个 研究和应用技术领域，从构建宇宙模型到产生明天的 气象报告，计算机无不是必要的工具，并且它们的应 用本身就开辟了人们推测的新领域。CompBiblioteka ter Overview 计算机概览
