Answer 1

分析 本文是一篇記敘文．文章講述了北京天安醫(yī)院的耳鼻喉醫(yī)師Feng Yongfeng對(duì)長(zhǎng)期戴耳機(jī)的看法以及提出的建議．

解答 16．popularity 考查名詞．形容詞wide后，介詞of前，要接名詞，故填popularity．
17．while 考查連詞． 根據(jù)句意，這里表示在公園跑步或者坐公交車的時(shí)候，經(jīng)�？匆娙藗儙е�耳機(jī)．故用while引導(dǎo)．
18．them 考查代詞．根據(jù)句意，這里表示音量如此大以至于他們周圍的人都可以聽到，指代"戴耳機(jī)的那些人"，且位于介詞后，要用賓格形式，故填them．
19．potentially 考查副詞． 根據(jù)句意，這里是用來修飾動(dòng)詞damage，要用副詞形式，故填potentially．
20．to turn 考查固定詞組（非謂語動(dòng)詞）．動(dòng)詞tend后要用不定式to do作賓語，構(gòu)成tend to do sth"傾向于做某事"，故填to turn
21．without 考查介詞．根據(jù)句意，這里是指很多人沒有意識(shí)到這一點(diǎn)，故填without．
22．a(chǎn) 考查冠詞．根據(jù)句意，這里指有聽力問題的人的數(shù)量有一些輕微的增加，表泛指的增加，故填a．
23．which 考查定語從句．根據(jù)句子成分分析可知，F(xiàn)eng attributed to them wearing headphones at home for long periods during the holiday是一個(gè)非限制性定語從句，修飾前面的整個(gè)句子，指物，故用which引導(dǎo)．
24．a(chǎn)dvised 考查動(dòng)詞的時(shí)態(tài)．根據(jù)句意和句子成分分析可知，該空和前面的said一起做并列的謂語，故填advised．
25．investing 考查非謂語動(dòng)詞（ 固定句型）．worth后面要跟v-ing形式作賓語，構(gòu)成sth be worth doing結(jié)構(gòu)，故填investing．

點(diǎn)評(píng) 1．形容詞后of前一般要用名詞形式
2．若主、從句表示兩個(gè)同時(shí)進(jìn)行的持續(xù)性動(dòng)作，且強(qiáng)調(diào)主句表示的動(dòng)作延續(xù)到從句所指的整個(gè)時(shí)間，通常要用while．（如題17）
