24、.“玩”。3A隨著時間的推移，作者發(fā)現(xiàn)(found)電腦幾乎沒被碰過。4C根據(jù)下文中的“I decided to teach her”可推知，母親并不知道怎么(how)使用電腦，于是作者決定教她。5C根據(jù)空處前一句“I decided to teach her”和空后的“and she seemed OK with what I said”可推知，作者給母親講解(explained)了相關(guān)的電腦知識。6A根據(jù)語境可知，空處應(yīng)填連詞and，表示“然后，接著”。7D結(jié)合語境可推知，母親不會玩電腦，感到很泄氣(discouraged)。8D根據(jù)空前的“The screen saver(屏幕保護程序)

25、had appeared”及常識可推知，電腦出現(xiàn)屏幕保護程序，母親不知道怎么把它關(guān)掉。turn off“關(guān)掉”。9A根據(jù)空后的“and it didnt work”可推知，母親因為不懂得怎么關(guān)掉屏幕保護程序，于是就按(hitting)了每一個鍵。10B根據(jù)語境可推知，作者教母親稍微晃動(shake)鼠標(biāo)即可。下文中的“start shaking it”也是提示。11B根據(jù)語境可推知，作者是讓母親移動鼠標(biāo)，喚醒電腦。wake up“喚醒”，符合語境。12C根據(jù)空后的“start shaking it around in midair”可推知，母親聽了作者的話就把鼠標(biāo)拿起來(pick up)，在空

27、自己制作了一張賀卡(greeting card) ，對作者表示感謝。20B根據(jù)語境可知，此處指卡片貼在了作者的門上。stick to.意為“粘/貼在”。四、單句改錯1The story he told the police differed in the one he told his mother._答案：infromdiffer from . “和不同”。2Owed to her assistance, we succeeded in starting the engine._答案：OwedOwingowing to . “因為；由于”，為固定用法。3It suddenly struck

28、to me that we should make a new plan._答案：去掉toIt strikes sb. that . “某人突然想起”。4My mother makes a promise if I passed the exam, she would buy me a watch._答案：promise后加that該句為that引導(dǎo)的同位語從句，that雖不作成分，但也不能省略。5Encouraging by the speech, the young man made up his mind to take up the struggle._答案：EncouragingEn

29、couraged主語the young man 與encourage之間為被動關(guān)系，故應(yīng)用過去分詞作狀語。五、短文改錯Mike，a famous writer，lives just next door to me.He is always ready give a helping hand to others，but he enjoys great popularity in the neighborhood.He often teaches us how to write stories and encourages me about his own experience.He told t

32、He worked and overcame thousands of .Finally，he entered a university in he wrote many story books.Up till now， only forty，he has been very famous around the country.第一處：ready后加to。考查動詞不定式。be ready to do sth.為固定用法，意為“準(zhǔn)備好做某事；樂于做某事”。第二處：but改為and/so?？疾檫B詞。Mike樂于助人，因此他在社區(qū)很受歡迎。根據(jù)語境可知，此處用and/so連接兩個并列分句。第三處：u

33、s改為me?？疾榇~。第二段談及的都是Mike與作者本人之間的事，所以us改為me。第四處：about改為with?？疾榻樵~。Mike用他自己的經(jīng)歷鼓勵作者。with在此意為“以，使用”。第五處：刪除to。考查介詞。tell sb.sth.為固定用法，意為“告訴某人某事”。第六處：has改為had?？疾闀r態(tài)。根據(jù)句中的As a little boy可知，此處敘述的是過去的事，故用一般過去時。第七處：hardly改為hard?？疾楦痹~。Mike學(xué)習(xí)努力，克服了很多困難。hard“努力地”，符合語境。hardly意為“幾乎不”。第八處：difficulty改為difficulties。考查名詞的數(shù)。根據(jù)句中的thousands of可知，此處用名詞的復(fù)數(shù)形式。第九處：that改為which?？疾槎ㄕZ從句。定語從句的先行詞為university，關(guān)系詞作介詞in的賓語，所以用“in which”引導(dǎo)定語從句。第十處：aging改為aged?？疾樾稳菰~。aged為形容詞，意為“歲”，符合語境。我國經(jīng)濟發(fā)展進入新常態(tài)，需要轉(zhuǎn)變經(jīng)濟發(fā)展方式，改變粗放式增長模式，不斷優(yōu)化經(jīng)濟結(jié)構(gòu)，實現(xiàn)經(jīng)濟健康可持續(xù)發(fā)展進區(qū)域協(xié)調(diào)發(fā)展，推進新型城鎮(zhèn)化，推動城鄉(xiāng)發(fā)展一體化因：我國經(jīng)濟發(fā)展還面臨區(qū)域發(fā)展不平衡、城鎮(zhèn)化水平不高、城鄉(xiāng)發(fā)展不平衡不協(xié)調(diào)等現(xiàn)實挑戰(zhàn)。
