六、作文題(1題)54.Directions:Thispartistotestyourabilitytodopracticalwriting.Youarerequiredtowriteanessayaccordingtothefollowinginformationgiveninthepicture.Youshouldwriteyourcomposition（nolessthan100words）ontheAnswerSheet.

說明：下圖展現(xiàn)的是人們越來越依賴手機進行交流的現(xiàn)象，請你就這一現(xiàn)象進行評論。

參考答案

1.B如果你在拐角向右轉(zhuǎn)，你就會發(fā)現(xiàn)一條通往那座歷史建筑的路。

［考點］非謂語動詞

【精析】B

現(xiàn)在分詞或分詞短語可以作定語修飾名詞，分詞短語作定語一般放在被修飾詞之后。由于path和lead之間為邏輯上的主謂關(guān)系，故應(yīng)用lead的現(xiàn)在分詞形式。因此選擇B項

2.C建橋梁的地方應(yīng)設(shè)在跨河交通最繁忙的地方。

［考點］定語從句和表語從句

【精析】C分析句子結(jié)構(gòu)可知，place和should之間是定語從句。先行詞為Theplace，從句中缺少地點狀語，故空處應(yīng)為關(guān)系副詞where或介詞+which引導(dǎo)。be后為表語從句，從句中缺少狀語，所以應(yīng)用連接副詞where引導(dǎo)。故選C

3.D[答案]D

[譯文]現(xiàn)在每個人都在努力工作，過著幸福的日子，不是嗎？

[詳解]反間疑問句，因為前面是肯定，所以后面為否定，主語為每個人，所以反意疑問部分用復(fù)數(shù)，aren’tthey

4.A那時我們除了等以外，什么都不能做。

［考點］非謂語動詞

【精析】A在介詞but,except,besides后跟不定式做賓語時，如果介詞前有do及其變化形式時，不定式可省略to。選項中A、D均符合此用法，但but意為除了……，besides意為除了……還……。根據(jù)句意，選A

5.C最讓我感到驚訝的是，一個如此小的7歲男孩小提琴竟然拉得這么好。

［考點］主語從句和表語從句

【精析】C分析句子結(jié)構(gòu)可知，was前面是主語從句，從句中缺少主語,所以應(yīng)用what引導(dǎo)。was之后是表語從句，從句不缺少任何成分，所以應(yīng)用that引導(dǎo)，that在從句中不作句子成分,只起連接作用。故選C

6.B在酒店住一天的費用是租一星期公寓的兩倍。

［考點］倍數(shù)表達法

【精析】B常用的倍數(shù)表達法有：①A+謂語+倍數(shù)+as+形容詞或副詞的原級+as+B；②A+謂語+倍數(shù)+形容詞或副詞的比較級+than+B。根據(jù)句意可知，此處指的是花費的錢，所以應(yīng)用much來修飾。選項中只有B項符合要求。故選B

7.B你上次是在什么時候跟你兒時的伙伴聯(lián)系的？

［考點］詞語搭配

【精析】Bgetintouchwith為固定搭配，意為與……取得聯(lián)系。故選B

8.A他喜歡小說，然而我喜歡詩歌。

［考點］詞義辨析

【精析】Awhile:然而，雖然，常用來表示對比;because:因為;although:盡管，雖然;so:所以，因此。根據(jù)句意可知，此處含有對比、轉(zhuǎn)折之意，所以應(yīng)選A

9.B——你覺得你的新工作怎么樣？

——薪酬很不錯，但是升職前景并不樂觀。

［考點］詞義辨析

【精析】Binchargeof：負責(zé)；intermsof：就……來說，關(guān)于……；incaseof：萬一，倘若；infavorof：贊成，支持。根據(jù)句意可知，選B

10.B由于投身于科學(xué)工作中，他沒有時間關(guān)心家務(wù)事，他的妻子為此常常抱怨。

［考點］非謂語動詞

【精析】B分析句子結(jié)構(gòu)可知，空處應(yīng)用非謂語動詞，和第一個逗號前的部分一起作原因狀語。根據(jù)句意可知，he和devote之間是邏輯上的動賓關(guān)系，所以應(yīng)用過去分詞表被動。也可將bedevotedtosth.看作固定搭配，意為獻身于……，致力于……，此處省略了主語和be動詞。故選B

11.AAtension：緊張，不安;sadness：悲傷，傷心；anger：生氣，氣憤；relaxation：放松。根據(jù)句意可知，選A

12.A他有一件新的漂亮的意大利產(chǎn)的黑色皮夾克。

［考點］限定詞詞序

【精析】A多個形容詞作定語修飾同一個名詞時的排列順序是固定的，可記為以下口訣：限定描繪大長高，形狀年齡和新老；顏色國籍出材料，作用類別往后靠。句中的leather表示材料，應(yīng)緊挨著中心名詞，Italian表示國籍，應(yīng)放在材料前面，black是顏色，應(yīng)放在國籍前面，new表示新舊，應(yīng)放在顏色前面,beautiful為描述性詞匯，應(yīng)放在其他形容詞前面。故選A

13.B我認為小孩子往往比其他任何人更能欣賞現(xiàn)代繪畫。

［考點］詞義辨析

【精析】Banyone：任何人；anyoneelse：其他任何人；someone：某人；noone：沒有人。根據(jù)句意可知，選B

14.D該網(wǎng)站可能包含其他網(wǎng)站的鏈接，這些網(wǎng)站的隱私措施可能與我們的不同。

［考點］定語從句

【精析】D分析句子結(jié)構(gòu)可知，空處引導(dǎo)一個定語從句。空處指代的是先行詞otherwebsites，且與privacymeasures之間為所屬關(guān)系，所以應(yīng)用whose引導(dǎo)，在從句中作定語，相當于先行詞的所有格otherwebsites’。故選D

15.A人們的社會地位常常由他們擁有財富的多少來衡量。

［考點］詞義辨析

【精析】Ameasure：估量，衡量；examine：檢查；test：試驗，測試；question：詢問，審問。根據(jù)句意可知，選A

19.B他在部隊服役了十年，去年退役了。

［考點］動詞時態(tài)

【精析】B根據(jù)and后面分句中的謂語動詞retired和時間狀語lastyear可知，服役發(fā)生在退役這個動作之前，即發(fā)生在過去的過去，所以and前面的分句應(yīng)用過去完成時。故選B

20.A

21.KK根據(jù)空后的名詞短語15years可知，空處應(yīng)填介詞。符合要求的選項有C、K。句意：15年來，來自倫敦大學(xué)學(xué)院的專家們一直在調(diào)查超過6,700名英國人的生活方式。故選K。
