四、重点句型
1.what引导名词性从句
If you want to change your routine, you just say aloud what you want and the home system will obey.
如果你想改变你的日常工作,你只要大声说出你想要什么,家庭系统就会服从。
句式分析:句中what you want为what引导的名词性从句,作动词say的宾语。
[知识拓展]
(1)what引导的名词性从句除了可以作宾语外,还可以在句中作主语、表语或同位语等。
(2)what在所引导的名词性从句中充当一定的成分。
(3)what引导的名词性从句用陈述语序。
[提醒] 名词性从句中的what与that
what引导名词性从句常在从句中表示某种意义且作成分,而that引导名词性从句时,that在从句中一般无意义,且在从句中不作任何句子成分。
2. “特殊疑问词 +不定式”结构
(教材P15)It will also give you suggestions on a healthier diet and how to sleep better.
它还会为你提供更健康的饮食和如何睡得更好的建议。
句式分析:句中how to sleep better为“特殊疑问词 +不定式”结构,作介词on的宾语。
[知识拓展]
(1)常见的特殊疑问词:疑问代词who,what,which等和疑问副词how,when,where等。
(2)语法功能:该结构相当于名词性从句,在句中可以作主语、宾语、表语、同位语等(作主语时,谓语动词常用单数)。
(3)通常用在tell,show,understand,explain,teach,learn,discuss等动词后面的特殊疑问代词与构成不定式的动词之间为动宾关系时,不定式通常用主动形式。
3.before引导时间状语从句
(教材P15)Nevertheless, it will take some years before most new homes begin to use this new technology.
然而,要让大多数新家庭开始使用这项新技术还需要几年的时间。
[知识拓展]
(1)“It was +时间段 +before...”表示“过了多久才......”。从句常用一般过去时。
(2)“It was not long before...”意为“不久就......”。从句常用一般过去时。
(3)“It will not be long before...”表示“不久就会......”。从句常用一般现在时。
(4)“It will be +时间段 +before...”表示“要过多久才......”。从句常用一般现在时。
4. It + be + adj. +that......引导的主语从句
It is possible that this technological fantasy will come true in the distant future.
这种技术幻想有可能在遥远的未来实现。
【析】句子结构当that引导的从句作主语时,为了保持句子平衡,避免头重脚轻,通常把它移到句子后面,用it作形式主语,放到句首。that在句中仅起连接作用,不作成分,但不能省略。
It + be + adj. +that引导的主语从句句型中常见的形容词有obvious, clear, evident, true, possible, certain, likely, probable 等。
5.现在分词作定语
(教材P20)Probably the most well known are the Amish, a group of Christians living in rural America.
最著名的可能是阿米什人,一群生活在美国农村的基督徒。
句式分析:现在分词短语living in rural America作名词Christians的后置定语。
[知识拓展]
(1)现在分词(短语)作定语与所修饰的名词之间存在着逻辑上的主谓关系,表示该动作的主动和进行。
(2)单个现在分词作定语,放在所修饰词的前面,而现在分词短语作定语则放在所修饰词的后面。
6.make it ...(for sb.) to do...
(教材P20)Moreover, the Internet has made it possible for friends and family to keep in touch easily even if they are on opposite sides of the world.
此外,互联网使朋友和家人很容易保持联系,即使他们在世界的两端。
句式分析:句中made it possible for friends and family to keep in touch为“make it ...(for sb.) to do...”结构,意为“使(某人)做(某事)成为......”,形容词possible是宾语补足语。
[知识拓展]在make it...(for sb.) to do...结构中,it是形式宾语,to do...是真正的宾语。常用这种结构的动词还有find, feel, think, consider等。
7.as引导原因状语从句
(教材P20)It has also made finding opportunities in life much easier, as it allows people to make larger networks of friends through using social media.
它还让人们在生活中寻找机会更容易,因为它让人们通过使用社交媒体结交更多的朋友。
句式分析:as引导原因状语从句,既可放在主句前也可放在主句后。一般来说,as引导原因状语从句表示双方都知道的原因。
[知识拓展]
(1)引导时间状语从句,意为“当......时;一边......一边......;随着”。
(2)引导方式状语从句,意为“正如;就像”。
(3)引导让步状语从句,意为“尽管;虽然”,从句应倒装。
(4)引导比较状语从句,表示“像......一样地”。
五、单元语法:将来进行时
将来进行时(The Future Continuous)表示将来某一时刻或某一阶段内将要发生的动作。
将来进行时由“shall/will + be动词 + 现在分词”构成。shall用于第一人称,will用于各种人称。
1.将来进行时的构成
肯定句:主语 + shall/will + be + 现在分词...
否定句:主语 + shall/will + not + be + 现在分词...
疑问句:Shall/Will + 主语 + be + 现在分词...?
疑问代词/疑问副词 + shall/will + 主语 + be + 现在分词...?
2. 基本用法
(1) 表示将来某时刻正在进行的动作。如:
Don’t phone him between 5pm and 6pm. He’ll be having a meeting then.
五点至六点之间不要给他打电话,那时他在开会。
When I get home, my wife will probably be doing cooking. 当我到家时,我太太可能正在做饭。
(2) 表示按计划或安排要发生的动作。如:
The train won’t be leaving until one o’clock. 火车一点钟才开。
We shall be going to London next week. 下周我们要去伦敦。
(3) 常用来表示预计即将发生或势必要发生的动作。如:
When shall we be meeting next time? 我们下次什么时候见面?
Do come tomorrow! We’ll be expecting you. 明天务必来,我们要等你的。
3. 和一般将来时的区别
(1) 将来进行时表示将来某时正在进行的动作; 而一般将来时表示将来某时将要发生的动作。如:
What will you be doing at seven the day after tomorrow? 后天晚上七点会在做什么呢
What will you do at seven the day after tomorrow? 后天晚上七点你干什么?
(2) 将来进行表示已有的安排;而一般将来时表示临时决定。如:
I’ll go to see him after school. 放学后我去看她。
I’ll be going to see him after school. 放学后我准备去看她的。
(3) 两者均可表示将来,但用将来进行时语气更委婉,比较:
When will you finish your homework 你什么时候完成作业?
When will you be finishing your homework 你什么时候完成作业呢?
(4) 有时将来进行时则只是单纯地谈未来情况;而一般将来中的will含有“愿意”的意思。比较:
Mary won’t be paying this bill. 不会由玛丽来付钱。(单纯谈未来情况)
Mary won’t pay this bill. 玛丽不肯付这笔钱。(表意愿)

第二篇
Smart homes to make life easier
Have you ever forgotten to lock the door of your house? Or, have you ever forgotten to switch off the TV or computer? These kinds of things happen to us all the time, waste resources, and can sometimes lead to problems. 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 1 .______ the TV when we forget. These smart homes will keep us secure, save us energy, and provide a more comfortable environment to live in.
Intelligent Controls
Today, we have to use switches for our lights, knobs for our appliances, and remote controls for our TVs and air conditioners. In the future, we will be using advanced technology every day for automatic control of just about everything in our home. The future home will use 2. ______ (integrate) sensors to tell when you leave home each morning, and then go into an energy-efficient mode all by itself. You will no longer have to think about turning switches on and off yourself. Your home will also learn your daily routine and 3. ______ (prefer), so everything will be ready for you when you get home each evening. Your lights will come on 4 .______ instant you enter the door along with your favourite music or TV programmes, and you will find your dinner already prepared for you. All controls will respond to voice commands, so if you want to change your routine, you just say aloud what you want and the home system will obey.
Regular Health Checks
In addition, your smart home will be monitoring your health for you every day. Your bed, for example, will record how well you sleep every night. It will also be checking your body weight. If you start to have sleep or weight problems, it will send a 5 .______ (warn) to your phone. It will also give you suggestions on a 6. ______ (healthy) diet and how to sleep better. Smart toilets will be keeping constant track of your health as well. They can warn you early on if there is something 7 .______ (normal) or if you have a critical illness, such as cancer, and potentially save your life.
No More Disasters
Smart homes will be able to prevent serious damage from accidents. For example, if a water pipe starts leaking, or if there is a short in the electrical wiring, your smart home will detect it and provide you with the relevant information. This way, you will be able to fix the problem before your home becomes 8 .______ (flood) or catches fire.
This smart technology is not a fantasy. Many of these new 9 .______ (innovate) are already available and being used in some homes. 10 .______ this sense, the home of tomorrow is already the home of today. Nevertheless, it will take some years before most new homes begin to use this new technology.
