二、语法知识点
（一）一般将来时与将来进行时辨析
一般将来时：表示将来某个时间要发生的动作或存在的状态，也表示将来经常或反复发生的动作。
结构为 “will + 动词原形” 或 “be going to + 动词原形”。
例句：I will go to Beijing tomorrow.（我明天将去北京。）
He is going to have a party this weekend.（他这个周末打算举办一个派对。）
将来进行时：表示将来某一时刻或某段时间正在进行的动作。
结构为 “will be + 动词的现在分词”。
例句：This time tomorrow, I will be studying at school.
（明天这个时候，我将正在学校学习。）
两者区别：一般将来时侧重于表达对未来的计划、意图或预测；将来进行时更强调在未来某个具体时间点或时间段动作的持续性和正在进行的状态。
例如：I will write a letter tonight.（今晚我要写一封信，强调计划）
I will be writing a letter at 8 o'clock tonight.
（今晚 8 点我将正在写信，强调 8 点时动作正在进行）
（二）练习题

三、重要句式句型分析
（一）However, in the not-too-distant future, we will be living in smart homes that will lock the door for us when we are away and remember to switch off the TV when we forget.
结构分析：句子主干为 “we will be living in smart homes”，使用将来进行时，表示未来一段时间内持续的居住状态；“that will lock the door for us when we are away and remember to switch off the TV when we forget” 是 that 引导的定语从句，修饰先行词 “smart homes”，在定语从句中又包含两个 when 引导的时间状语从句。
（二）These smart homes will keep us secure, save us energy, and provide a more comfortable environment to live in.”
结构分析：句子采用 “主语 + 谓语 + 宾语 + 宾语补足语” 结构，“These smart homes” 是主语，“will keep, save, provide” 是并列谓语，“us, energy, a more comfortable environment” 分别是对应的宾语，“secure, a more comfortable environment to live in” 是宾语补足语，补充说明宾语的状态或情况 。
（三）翻译练习题

（三）参考范文
My Views on Future Technology
With the rapid development of science and technology, our future life will be greatly changed. In my opinion, future technology will bring us both opportunities and challenges.
On the one hand, future technology will undoubtedly bring numerous benefits. Smart homes will make our lives more convenient and comfortable. They can automatically control the temperature, lighting, and security systems, saving us time and energy. Driverless cars will improve traffic safety and reduce the burden of driving. Moreover, artificial intelligence will assist us in various fields, such as healthcare, education, and work, making our lives more efficient. For example, AI - powered robots can help doctors perform complex surgeries more accurately, and intelligent tutoring systems can provide personalized learning experiences for students.
On the other hand, we should also be aware of the potential challenges. The widespread use of technology may lead to job losses as many traditional jobs are replaced by machines and AI. Privacy and security issues will become more serious. For instance, personal information collected by smart devices may be at risk of being leaked. Additionally, over - reliance on technology may weaken our basic skills and interpersonal communication abilities.
To sum up, future technology is a double - edged sword. We should embrace it with a rational attitude, take advantage of its benefits, and take measures to address the potential problems. Only in this way can we ensure that future technology serves us better and makes our world a better place.
