说明
when

当我进屋时，他正在写信。
when指的是“某一具体的时间”。
while
① While it was raining, they went out.
正当天下雨的时候，他们出去了。
②I stayed while he was away.
他不在的时候而我在。(然而)
③All of us are working hard while he is sleeping.(然而，并列连词)
①while指“在某一段时间里”，“在┉期间”，有时表示主从句的轻微转折，译为：“然而”
②while引导的动作必须是持续性的。
as
① He hurried home, looking behind as he went.
他赶快回家，一边走一边向后看。
② As time goes by, I like China better.
随着时间的流逝，我越来越喜欢中国。
①as （译为“一边……一边”）引导持续性动作，强调主句和从句的动作同时发生；
②as译为“随着……”
before
① I finished my task before I went home.
我做完作业才回家。
② Be a pupil before you become a teacher.先做学生，再做先生。
在….以前
after
He arrived after the game started.
比赛开始后，他到了。
after“在┉之后”
till
until
①We waited till(until)he came back .
我们一直等到他回来。
②She didn’t stop working until eleven o’clock .
她直到11点钟才停止工作。
③Until he had passed out of sight, she stood there.
她站在那里看着，直到看不见他的身影。
①如主句动词是持续性动作，常用肯定式，表示“直到……为止”；
②not…until…表示“直到…才…”“在…以前不…”。
主句通常用瞬间动词。这时until可用before替换。
【例】He didn’t leave until/before I came back.
有时可用never, nothing代替not.
③ 如果从句放在句首表示强调，一般用until, 不用till.
since
Great changes have taken place in China since 1978.
自从1978年以来中国发生了巨大的变化。
主句动词为持续性的，从句动词为瞬间的。
①如果状语从句在主句之前时一般用逗号与主句分开；②如果从句在主句之后则不必用标点符号。
as soon as
①As soon as I arrive in Shanghai, I’ll write to you.我一到上海就给你写信。
②My brother went out as soon as I got home.
③I'll phone you as soon as I arrive in Tonghua.
as soon as 表示主句发生的动作发生在从句动作之后， 意为“一…就…”。如果主句是一般将来时，情态动词加动词原形或祈使句时，时间状语从句用一般现在时。
当主句是一般过去时，从句一般也用一般过去时，简言之：主将从现；主过从过
Whenever
①Whenever he sees the book, he will think of the good memory.
无论何时，他看到那本书，他都会想起美好的记忆。
whenever = no matter when

【答案】D
【解析】
句意：——史米斯先生，请今天教我怎样用电脑画画。——哦，不。心急吃不到热豆腐。你必须先熟悉键盘。考查谚语理解题。A. It’s never too old to learn活到老学到老。B. Think twice before you do三思而后行。C. Don’t be a wet blanket不要煞风景。D. Learn to walk before you run心急吃不到热豆腐。根据句意语境，可知Learn to walk before you run符合语境，故选D。
2.—When will she go home?
—She ______ home ___ she finishes her homework.
A. won’t go ; before, B. goes,;before
C. won’t go; until D.go,;after
【答案】C
【解析】

A.when your brother comes back； when he will come back
B.when your brother will come back； when he comes back

D.when your brother will come back； when he will come back
【答案】B
【解析】
句意：-你能告诉我你哥哥什么时候回来吗? —对不起， 我不知道。他回来时我会打电话给你。when在前一句中，是特殊疑问词“什么时候”，在宾语从句中使用陈述句的语序；when在后一句中，意思是 “当……时候”，引导时间状语从句， 用一般现在时代替将来时。所以选B。
4.一What were you and your parents doing_______it began to rain last night?
一I was doing my homework________my parents were watching TV.
A.when；when B.while；while
C.when；while D.while；when
【答案】C
【解析】
句意：——昨晚开始下雨的时候你和你父母正在干什么？——我正在做家庭作业，而我的父母正在看电视。第一空引导时间状语从句，且began是瞬间性动词，所以用when引导。第二空前后两句时态一致，且动作几乎同时进行，所以用while连接并列结构。故答案选C。
5.She didn’t go to work ______ that morning. She slept ______ noon.
A./…till B.on…till C.at…at D./…at
【答案】A
【解析】
句意：那天早晨她没去上班，她一直睡到了中午。考查介词用法。当morning被that修饰时前面不能跟介词，排除AD；till noon表示一直到中午。故选A。
6.— _______ will the meeting between the two National leaders last?
—_______ they reach an agreement.
A.When,Until B.When,Not until
C.How long,Until D.How long,Not until
【答案】C
【解析】
句意：——两国领导人之间的会议会持续多久？ ——直到他们达成了协议。考查特殊疑问句，When什么时候（提问具体的时间）；Until直到；How long多久（问时间）；not…until直到……才，但通常不用not until。分析句意，可知第一句是问会议持续多长时间，用How long提问，回答是直到他们达成共识。用Until。故选C。
7.The Greens have_____ the flat in the centre of city_______ five years ago.
A.bought; since B.bought; for C.had; since D.had; for
【答案】C
【解析】
句意为：格林一家从五年前起就住在市中心的那套公寓里。bought买（buy的过去式和过去分词）；had有；吃；得到（动词have的过去式和过去分词）； for给，对，供；以帮助，为了； 关于；since因为；由于；既然；自…以来；自…以后。综合分析前后句， 可知此处填had; since最合适，依据 five years ago.表示自此之后。这之后一直延续至今，故用延续性动词had，bought是短暂性动词。正确答案为：C
8.He called me __________ he started. And __________ he arrives, I’ll meet him at the airport.
A.after; because B.before; as soon as
C.while; when D.until; as soon as

能力拓展
一．单项选择。
1.—I want to know when ______ have a field trip.
—We’ll have it when all the work ______.
A.you are; will finish B.you will; finishes
C.you will; is finished D.you will; is finish
【答案】C
【解析】
句意：——我想知道你们什么时候去郊游。——等所有的工作都完成了，我们就去了。考查动词时态。根据句子结构分析可知，第一句为宾语从句，主句为一般现在时，从句时态不限，因为郊游的事情发生在将来，所以从句时态应用一般将来时；第二句为when引导的时间状语从句，遵循“主将从现”的原则，所以此从句应为一般现在时，又因为从句主语“all the work”和动词 “finish（完成）”为被动关系，所以从句应用一般现在时的被动语态。故选C。
2.While the woman_________ , the accident happened.
A.drove B.was driving C.is driving D.drives
【答案】B
【解析】
句意：正当那位妇女开车时，事故发生了。while当……的时候；与它连用的时态为进行时态，根据后面的happened判断，前一个句子为过去进行时态，故答案为B。
3.Jim’s mother was cooking while he on the Internet.
A.is chatting B.chatting C. was chatting D.chats
【答案】C
【解析】
句意：吉姆的妈妈做饭的时候，同时他在网上聊天。根据while一词可知主从句的动作是同时进行的，所以该用过去进行时，故选C。
4. I_____ go home ______the concert was over.
A.didn’t; until B.wasn’t; till C.don’t; until D.won’t; till
【答案】A
【解析】
句意：直到音乐会结束我才回家。考查until用法。not …until…直到……才……，因为the concert was over是过去式，所以主句也要用过去时，排除C/D选项；go 是实义动词，要找助动词did在其后加not，故选A。
5.—I'm looking forward to the film A Road To Spring. ________ will it be first shown?
—________ the 28th August, 2020.
A.When; Until B.When; Not until C.How long; Until D.How long; Not until
【答案】B
【解析】
句意：——我期待着电影《春天之路》。这部电影什么时候上映？——直到2020年8月28日才首映。考查疑问词辨析和until用法。when什么时候，表时间；how long多长，问一段时间；until直到，和not连用表示“直到……才”，引导时间状语从句。根据回答“the 28th August, 2020”是问电影什么时候上映，when符合句意；结合语境，“它直到2020年8月28日才会首次上映”，即it won't be first shown until the 28th August, 2020.，可知答句是“not…until”结构，故选B。
6.They ________ in 2008 and they have had a happy family ________ 2008.
A. were married; since B. got married; in
C. married; from D. got married; since
【答案】D
【解析】

A.as soon as B.until C.if D.so that
【答案】A
【解析】
句意：铃声一响，学生们就匆忙赶到教室。A. as soon as 连词，一...就...，引导时间状语从句; B. until连词，直到，引导时间状语从句， 主句若是肯定句，动词为延续性动词，而hurried为暂时性动词；C. if 连词，是否或如果，引导宾语从句或条件状语从句；D. so that为了，引导目的状语从句。根据上下文关系可知, 表示时间关系“一...就...”。故选：A。
8.He climbed up the ladder __________ the wall and went into the room __________ the open window.
A.through； against B.against； through
C.against； against D.through； through
【答案】B
【解析】
句意：他爬上在墙上的梯子，并且通过窗户走进房间。结合句意，against表示反对……；through表示内部的通过穿过。故选B。
分层提分
题组A 基础过关练
一、用所给单词的正确形式填空。
1.These trees should ________（water）after they ________（plant）.
【答案】be watered are planted
【解析】
句意：这些树种好后应该浇水。主从句的主语和动词之间都是动宾关系，故空一应用含有情态动词的被动语态，构成形式为should be done；water的过去分词是watered；空二应用一般现在时的被动语态，构成形式为be done；主语“they”是复数形式，be用are；plant的过去分词是planted。故填be watered；are planted。
2.After he got home, the new_______ (spread).
【答案】had been spread
【解析】
句意：他到家后，新消息已经传开了。根据“After he got home”可知，“到家”的动作发生在过去，“消息已经传开了”是过去的过去，主语是the new，和谓语之间存在被动关系，此处用过去完成时的被动语态，其结构是had been done的形式。spead是动词，扩散。过去分词是spread。故填had been spread。
3.I ________ (watch) TV when someone knocked at the door.
【答案】was watching
【解析】
句意：当有人敲门的时候，我正在看电视。本题是由when引导的时间状语从句，其时态为一般过去时，因此看电视是在过去的某个时间内正在发生的动作，因此用过去进行时。其形式为was /were + V-ing。此题的主语是I，因此be动词用was。故答案为：was watching。
4.Don’t make much noise when ______ (read) in the library.
【答案】reading
【解析】
句意：在图书馆看书时不要大声喧哗。此句为“主祈从现”结构，即Don’t make much noise when you are reading in the library.因为表示“正在图书馆读书”，所以是现在进行时态。在时间状语从句中，如果主从句主语一致，从句的主语+be可以省略。故填reading。
5.When the chairman _________ (finish) speaking, he _________ (leave)the hall.
【答案】(had) finished left
【解析】
句意：当主席（已经）说完，他离开了大厅。本句讲述过去的一件事情，所以应该用一般过去时，finish的过去式为finished；leave的过去式为left。或者如果强调“结束讲话”在“离开”这个动作发生之前，那么第一个空也可以用过去完成时，其构成“had+动词的过去分词”，finish的过去分词为finished，故填(had) finished；left。
6.I ________ (do) my homework while they ________ (talk).
【答案】was doing were talking
【解析】
句意：他们在谈话时，我正在做我的家庭作业。分析句子可知，本句要表达的是“某人正在做某事时，其他人正在做某事”，即主从两句都是进行时；由于句子陈述的是发生过的事情，所以要用过去进行时，即要用“was/were+V-ing”的结构；主句主语是“I”，所以do要变成“was doing”，从句主语是“they”，所以talk要变成were talking，故填was doing；were talking。

Is your TV connected to the Internet? What about your chair or your fridge? It is possible that they are not. But in the future, most things in your home may be connected, as the so-called "Internet of things" is developing.
The Internet of things may be coming sooner than you think. It is reported that during his speech earlier this year, Samsung CEO(首席执行官) BK Yoon spent a lot of time talking about the Internet of things. He said that five years from now, every Samsung product will be part of the Internet of things, whether it's a washing machine or a vacuum cleaner(吸尘器).
So, how do household(家用) objects that are part of Internet of things work? Well, think of a usual chair. When connected to the Internet, the chair warms up when it knows that the user has just walked into the room and is feeling cold.
An Internet-connected camera, like a smart-home camera, could help people feel safer in their homes. It can recognize(识别) people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there. If the person is someone you don't know, it can tell you that, too.
But according to MIT Technology Review, whether companies are connecting dog food bowls or security(安全) systems to the Internet, there may be problems. For example, many early connected-home devices(装置) don't have much built-in security, which means they could be hacked(被黑客攻击). In addition, it could be difficult to get these devices to work together because they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2014.
So, picture this: you walk in through the front door of your home. The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.
6.The Samsung CEO's speech is mentioned to prove that_____.
A.the Internet of things will appear in our daily life sooner
B.Samsung has produced the Internet of things recently
C.Samsung products have been part of the Internet of things
D.he spent a lot of time talking about the Internet of things
7.We can infer(推断)from paragraphs 3 and 4 that _____________.
A.the chair can know whether the user feels cold or not
B.a usual chair can warm up when it knows the user comes in
C.an Internet-connected camera can be used to take photos in the house
D.an Internet-connected camera can be connected to the user's smartphone
8.According to the passage, it is mentioned that_____
①the temperature inside is neither too high nor too low
②your fridge provides the drinks for you
③the chair warms up if you feel cold
④your favourite music starts playing
⑤your washing machine starts working
A.①②⑤ B.②③④ C.①③④ D.①④⑤
9.What's the problem about the Internet of things?
A.Companies which produce connected-home devices haven't joined together.
B.Connected-home devices may not work together and can easily get hacked.
C.Companies have difficulty connecting security system to the Internet.
D.These new devices are produced by different companies.
10.What is the main idea of the passage?
A.How to product the Internet of things.
B.The introduction to use the Internet of things.
C.The way of connecting the Internet of things.
D.The Internet of things is coming in the future.
【答案】ADCBD
【文章大意】
本文是一篇科技说明文文。主要讲述以后的家用设施将会更多地与网络相连，更加智能化。
【解析】
6.A细节理解题。第二段引用三星CEO的这段话主要目的是为了证明第二段的第一句话“The Internet of things may be coming sooner than you think.” （物联网可能比你想象的要快）。所以选 A。
7.D细节理解题。根据第四段中It can recognize(识别) people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there.可知它可以识别人们的脸，甚至可以在黑暗中看到有人通过。然后它可以给你发送一个消息到你的智能手机，让你知道谁在那里。所以该选D。
8.C细节理解题。根据最后一段“The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you.”可知①和④是对的，排除A和B。根据“the chair warms up when it knows that the user has just walked into the room and is feeling cold.”可知③是对的，所以选C。
9.B细节理解题。倒数第二段关于问题列举了两个例子“For example, many early connected-home devices(装置) don't have much built-in security, which means they could be hacked(被黑客攻击). In addition, it could be difficult to get these devices to work together because they are made by different comp anies.”一个是容易被黑客攻击，还有一个就是有可能不兼容，只有B两点都提及到了。所以选B。
10.D主旨大意题。根据本文主要讲述以后的家用设施将会更多地与网络相连，更加智能化可知该选D。

主句通常用瞬间动词。这时until可用before替换。
【例】He didn’t leave until/before I came back.

since

as soon as 表示主句发生的动作发生在从句动作之后， 意为“一…就…”。如果主句是一般将来时，情态动词加动词原形或祈使句时，时间状语从句用一般现在时。
当主句是一般过去时，从句一般也用一般过去时，简言之：主将从现；主过从过

D.when your brother will come back； when he will come back
【答案】B
【解析】
句意：-你能告诉我你哥哥什么时候回来吗? —对不起， 我不知道。他回来时我会打电话给你。when在前一句中，是特殊疑问词“什么时候”，在宾语从句中使用陈述句的语序；when在后一句中，意思是 “当……时候”，引导时间状语从句， 用一般现在时代替将来时。所以选B。
4.一What were you and your parents doing_______it began to rain last night?

A.bought; since B.bought; for C.had; since D.had; for
【答案】C

8.He called me __________ he started. And __________ he arrives, I’ll meet him at the airport.
A.after; because B.before; as soon as
C.while; when D.until; as soon as

能力拓展
一．单项选择。
1.—I want to know when ______ have a field trip.
—We’ll have it when all the work ______.
A.you are; will finish B.you will; finishes
C.you will; is finished D.you will; is finish
【答案】C
【解析】
句意：——我想知道你们什么时候去郊游。——等所有的工作都完成了，我们就去了。考查动词时态。根据句子结构分析可知，第一句为宾语从句，主句为一般现在时，从句时态不限，因为郊游的事情发生在将来，所以从句时态应用一般将来时；第二句为when引导的时间状语从句，遵循“主将从现”的原则，所以此从句应为一般现在时，又因为从句主语“all the work”和动词 “finish（完成）”为被动关系，所以从句应用一般现在时的被动语态。故选C。
2.While the woman_________ , the accident happened.
A.drove B.was driving C.is driving D.drives
【答案】B
【解析】
句意：正当那位妇女开车时，事故发生了。while当……的时候；与它连用的时态为进行时态，根据后面的happened判断，前一个句子为过去进行时态，故答案为B。
3.Jim’s mother was cooking while he on the Internet.
A.is chatting B.chatting C. was chatting D.chats
【答案】C
【解析】
句意：吉姆的妈妈做饭的时候，同时他在网上聊天。根据while一词可知主从句的动作是同时进行的，所以该用过去进行时，故选C。
4. I_____ go home ______the concert was over.
A.didn’t; until B.wasn’t; till C.don’t; until D.won’t; till
【答案】A
【解析】
句意：直到音乐会结束我才回家。考查until用法。not …until…直到……才……，因为the concert was over是过去式，所以主句也要用过去时，排除C/D选项；go 是实义动词，要找助动词did在其后加not，故选A。
5.—I'm looking forward to the film A Road To Spring. ________ will it be first shown?
—________ the 28th August, 2020.
A.When; Until B.When; Not until C.How long; Until D.How long; Not until
【答案】B
【解析】
句意：——我期待着电影《春天之路》。这部电影什么时候上映？——直到2020年8月28日才首映。考查疑问词辨析和until用法。when什么时候，表时间；how long多长，问一段时间；until直到，和not连用表示“直到……才”，引导时间状语从句。根据回答“the 28th August, 2020”是问电影什么时候上映，when符合句意；结合语境，“它直到2020年8月28日才会首次上映”，即it won't be first shown until the 28th August, 2020.，可知答句是“not…until”结构，故选B。
6.They ________ in 2008 and they have had a happy family ________ 2008.

C. married; from D. got married; since

8.He climbed up the ladder __________ the wall and went into the room __________ the open window.
A.through； against B.against； through
C.against； against D.through； through
【答案】B

分层提分
题组A 基础过关练
一、用所给单词的正确形式填空。
1.These trees should ________（water）after they ________（plant）.
【答案】be watered are planted
【解析】
句意：这些树种好后应该浇水。主从句的主语和动词之间都是动宾关系，故空一应用含有情态动词的被动语态，构成形式为should be done；water的过去分词是watered；空二应用一般现在时的被动语态，构成形式为be done；主语“they”是复数形式，be用are；plant的过去分词是planted。故填be watered；are planted。
2.After he got home, the new_______ (spread).
【答案】had been spread
【解析】
句意：他到家后，新消息已经传开了。根据“After he got home”可知，“到家”的动作发生在过去，“消息已经传开了”是过去的过去，主语是the new，和谓语之间存在被动关系，此处用过去完成时的被动语态，其结构是had been done的形式。spead是动词，扩散。过去分词是spread。故填had been spread。
3.I ________ (watch) TV when someone knocked at the door.
【答案】was watching
【解析】
句意：当有人敲门的时候，我正在看电视。本题是由when引导的时间状语从句，其时态为一般过去时，因此看电视是在过去的某个时间内正在发生的动作，因此用过去进行时。其形式为was /were + V-ing。此题的主语是I，因此be动词用was。故答案为：was watching。
4.Don’t make much noise when ______ (read) in the library.
【答案】reading
【解析】
句意：在图书馆看书时不要大声喧哗。此句为“主祈从现”结构，即Don’t make much noise when you are reading in the library.因为表示“正在图书馆读书”，所以是现在进行时态。在时间状语从句中，如果主从句主语一致，从句的主语+be可以省略。故填reading。
5.When the chairman _________ (finish) speaking, he _________ (leave)the hall.
【答案】(had) finished left
【解析】
句意：当主席（已经）说完，他离开了大厅。本句讲述过去的一件事情，所以应该用一般过去时，finish的过去式为finished；leave的过去式为left。或者如果强调“结束讲话”在“离开”这个动作发生之前，那么第一个空也可以用过去完成时，其构成“had+动词的过去分词”，finish的过去分词为finished，故填(had) finished；left。
6.I ________ (do) my homework while they ________ (talk).
【答案】was doing were talking
【解析】
句意：他们在谈话时，我正在做我的家庭作业。分析句子可知，本句要表达的是“某人正在做某事时，其他人正在做某事”，即主从两句都是进行时；由于句子陈述的是发生过的事情，所以要用过去进行时，即要用“was/were+V-ing”的结构；主句主语是“I”，所以do要变成“was doing”，从句主语是“they”，所以talk要变成were talking，故填was doing；were talking。

Is your TV connected to the Internet? What about your chair or your fridge? It is possible that they are not. But in the future, most things in your home may be connected, as the so-called "Internet of things" is developing.
The Internet of things may be coming sooner than you think. It is reported that during his speech earlier this year, Samsung CEO(首席执行官) BK Yoon spent a lot of time talking about the Internet of things. He said that five years from now, every Samsung product will be part of the Internet of things, whether it's a washing machine or a vacuum cleaner(吸尘器).
So, how do household(家用) objects that are part of Internet of things work? Well, think of a usual chair. When connected to the Internet, the chair warms up when it knows that the user has just walked into the room and is feeling cold.
An Internet-connected camera, like a smart-home camera, could help people feel safer in their homes. It can recognize(识别) people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there. If the person is someone you don't know, it can tell you that, too.
But according to MIT Technology Review, whether companies are connecting dog food bowls or security(安全) systems to the Internet, there may be problems. For example, many early connected-home devices(装置) don't have much built-in security, which means they could be hacked(被黑客攻击). In addition, it could be difficult to get these devices to work together because they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2014.
So, picture this: you walk in through the front door of your home. The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.
6.The Samsung CEO's speech is mentioned to prove that_____.
A.the Internet of things will appear in our daily life sooner
B.Samsung has produced the Internet of things recently
C.Samsung products have been part of the Internet of things
D.he spent a lot of time talking about the Internet of things
7.We can infer(推断)from paragraphs 3 and 4 that _____________.
A.the chair can know whether the user feels cold or not
B.a usual chair can warm up when it knows the user comes in
C.an Internet-connected camera can be used to take photos in the house
D.an Internet-connected camera can be connected to the user's smartphone
8.According to the passage, it is mentioned that_____
①the temperature inside is neither too high nor too low
②your fridge provides the drinks for you
③the chair warms up if you feel cold
④your favourite music starts playing
⑤your washing machine starts working
A.①②⑤ B.②③④ C.①③④ D.①④⑤
9.What's the problem about the Internet of things?
A.Companies which produce connected-home devices haven't joined together.
B.Connected-home devices may not work together and can easily get hacked.
C.Companies have difficulty connecting security system to the Internet.
D.These new devices are produced by different companies.
10.What is the main idea of the passage?
A.How to product the Internet of things.
B.The introduction to use the Internet of things.
C.The way of connecting the Internet of things.
D.The Internet of things is coming in the future.

6.A细节理解题。第二段引用三星CEO的这段话主要目的是为了证明第二段的第一句话“The Internet of things may be coming sooner than you think.” （物联网可能比你想象的要快）。所以选 A。
7.D细节理解题。根据第四段中It can recognize(识别) people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there.可知它可以识别人们的脸，甚至可以在黑暗中看到有人通过。然后它可以给你发送一个消息到你的智能手机，让你知道谁在那里。所以该选D。
8.C细节理解题。根据最后一段“The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you.”可知①和④是对的，排除A和B。根据“the chair warms up when it knows that the user has just walked into the room and is feeling cold.”可知③是对的，所以选C。
9.B细节理解题。倒数第二段关于问题列举了两个例子“For example, many early connected-home devices(装置) don't have much built-in security, which means they could be hacked(被黑客攻击). In addition, it could be difficult to get these devices to work together because they are made by different comp anies.”一个是容易被黑客攻击，还有一个就是有可能不兼容，只有B两点都提及到了。所以选B。
10.D主旨大意题。根据本文主要讲述以后的家用设施将会更多地与网络相连，更加智能化可知该选D。
