Answer 1

分析 本文是一段對(duì)話，是凱特博士和鮑勃之間關(guān)于收音機(jī)用途的一段對(duì)話．自從我們還年輕的時(shí)候，收音機(jī)已經(jīng)改變了很多，它曾經(jīng)是家庭娛樂的主要來源．現(xiàn)在當(dāng)你打開收音機(jī)，你或者聽音樂、脫口秀或者新聞．

解答 61．has changed 考查現(xiàn)在完成時(shí)．根據(jù)since we were young，可知這里用現(xiàn)在完成時(shí)．故填 has changed．
62．to 考查固定搭配．used to do sth是固定用法，意為"過去常常做某事"．故填to．
 63．or 考查連詞．根據(jù)句意"現(xiàn)在當(dāng)你打開收音機(jī)，你或者聽音樂、脫口秀或者新聞"，可知此處表示選擇關(guān)系，故填or．
 64．Fortunately 考查副詞．位于句首，有逗號(hào)隔開，修飾整個(gè)句子的應(yīng)用副詞，故填Fortunately．
65．listening考查非謂語(yǔ)．enjoy后的動(dòng)詞應(yīng)用動(dòng)名詞形式，enjoy doing是固定用法，意為"喜歡做某事"．故填listening．
66．who 考查定語(yǔ)從句．根據(jù)空后的have可知，此處做主語(yǔ)指代先行詞those，所以是定語(yǔ)從句，因先行詞是those，故填who．
67．while/when 考查狀語(yǔ)從句．句意：看起來人們只在開車的時(shí)候，才會(huì)聽收音機(jī)．故用while/when．
 68．a(chǎn)t 考查介詞．固定短語(yǔ)at home意為"在家"．故填at．
69．playing 考查非謂語(yǔ)．have sth．doing是固定用法，sth．與動(dòng)詞是主動(dòng)關(guān)系，意為"使某物一直做某事"．此處表示"讓收音機(jī)一直開著"，故填playing．
70．communication考查名詞．根據(jù)句子結(jié)構(gòu)可知，此處為of形式的名詞所有格，所以介詞 of之后用名詞形式，故填communication．

點(diǎn)評(píng) 語(yǔ)法填空是通過語(yǔ)篇在語(yǔ)境中考查語(yǔ)法知識(shí)的運(yùn)用能力，在解題前應(yīng)快速瀏覽短文掌握大意，在讀懂短文的基礎(chǔ)上，結(jié)合短文提供的特定的語(yǔ)言環(huán)境去逐句分析，逐題解答．扎實(shí)的語(yǔ)法功底加上準(zhǔn)確的理解至關(guān)重要．
