We use language for all kinds of reasons, but the major one is to talk to each other. We use it to have a chat, play a game, tell jokes, ask for help, and do a thousand other things. ____26____ The everyday use of language is to have conversations with each other.

Having a conversation seems like the most natural thing in the world. We don’t think twice about it now. But it wasn’t always that way. We had to learn how to do it. ____27____

What’s the most basic rule of having a successful conversation? We take turns. I speak and then you do and then I do and then you do. ____28____ In an argument, we do sometimes hear a lot of people speaking together. But once the argument ends, everyone takes turns again.

This is especially important if there are several people taking part in a conversation. Imagine: you’re in the street talking to three other people about the latest film Dear You. ____29____ If it’s going to be a successful conversation, then all four of you need to get the chance to have your say. If that happens, everyone’s happy. If that doesn’t happen, you can end up feeling quite mad.

____30____ We have to learn how to do it. And babies start that learning process (过程) very early on, during the first year of life. They hear their mother talking… they coo or babble... the mother replies… they coo or babble again… the mother replies again. Listen-speak-listen-speak-listen. That’s the key of any conversation. We have to learn to be listeners as well as speakers.

A. We had to learn rules.

B. We don’t speak at the same time.

C. Some people are always cutting in.

D. Turn-taking doesn’t come naturally.

E. Everyone has got something to say about it.

F. None of these could happen without language.

G. We have learned all the sounds in our language.

A

B

C

D

解析：选F。细节过渡句。空格前文列举语言的各类用途：聊天、玩游戏、讲笑话、求助等。F 选项 “没有语言，这些都无法实现”，these指代上文中一系列行为，承接上文，引出下句语言用于对话。排除：G 讲语言发音，本段主题不是发音；A 讲规则，规则在后文才出现。

A

B

C

D

解析：选A。段落结尾过渡句。前文：对话看似自然，但并非向来如此，我们必须学会怎样对话。A “我们必须学习规则” 承接上句，开启下一段对对话基本规则（轮流说话）的讲解。逻辑：学会对话 → 学习对话规则，引出下文主体内容。

3.28.

A

B

C

D

解析：选B。细节阐释句。上句点明对话要轮流说话：我说、你说、我说、你说。B “我们不同时说话” 是对 “轮流发言” 的进一步解释。后文转折：争吵时会多人同时讲话，争吵结束又恢复轮流。B 和后文 “In an argument…speaking together” 形成正常情况和争吵特殊情况的对比。

4.29.

A

B

C

D

解析：选E。细节句（语义承接）。前文场景：你和另外三个人讨论最新电影。E “每个人对此都有话要说” 中it指代前面提到的电影。后句 “四个人都要有发言机会” 正好承接 “人人都有想说的内容”，逻辑连贯。C “有些人总插嘴”，后文没有围绕插嘴展开论述，排除。

5.30.

A

B

C

D

解析：选D。段首主旨句。空格为本段段首。后文：我们得学习怎么做；婴儿很早就开始学习听和说。D “轮流发言并非与生俱来” 统领整段，说明轮流说话是后天学习得来，和下文婴儿学习过程呼应。
