2.C

3.A

4.D解析：選項A、B、C均為細節(jié)用來說明D這一中心意思。

5.D

6.A

7.B概括文章最后一段可知，作者建議我們，改變無所謂大小，只要必要就需要改變。A項是對文章的片面理解；C項是文章的細節(jié)，不是段落的主旨。

8.A推理判斷題。

【應(yīng)試指導(dǎo)】從第五段第一句話可知，狄更斯寫作沒有帶著憤恨和生氣的感情，他認為正是童年那些磨難把他塑造成現(xiàn)在的他。因此狄更斯應(yīng)該是感激他的童年經(jīng)歷的。

9.A解析：見原文第二段。馬可尼沒有得到意大利政府的資助便前往英國從事研究工作。

10.C

11.D文章第二段第二句Therichnessoftheirmindprovestobemorebeautiful…表明作用認為女性的心靈美比外表美更吸引人。

12.A

13.D解析：從全文來看，Jones逃離監(jiān)獄、參加海軍、并領(lǐng)導(dǎo)海軍贏得勝利。所以說他是勇敢的、無畏的。選項D是正確的。

14.B解析：第三段，人們認為蘇格蘭不過是英格蘭的擴展，這種觀點對蘇格蘭人是莫大的冒犯(Indeed，noattitudeiscapableofcausinggreateroffencetotheScots)。

15.D第三段中寫道英國現(xiàn)在的氣候太冷不適合鱷魚居住。

16.D“splitup”一詞出現(xiàn)在文中第二段第三句，根據(jù)該短語所在句，我們可以得知，“splitup”與其后的“meetagain”意思相反。

17.D

18.B本文是介紹TakeOurDaughterstoworkDay這樣一個特殊的日子的設(shè)立及其意義，所以B項為最佳標題。

19.A第四段第一句Getofftoaslowstart，whichsavesyourenergy．之后，接著講到具體的例子，因此答案選A。

20.A“hibernation”既然是一個“seasonalpractice(季節(jié)性的做法)”，可以推測它可能僅發(fā)生在特定的季節(jié)。只有A項符合題意，故選A。

21.B解析：細節(jié)推斷題。根據(jù)第一段“Atypicalcourseconsistsofthreeclassesperweekforfifteenweeks；WhileattendingauniversityastudentWillprobablyattendfourorfivecoursesduringeachsemester"可得出正確答案為B。

22.B43．答案為B

文章第3段第3句Fearisthebiggestproblemfacedbychildrenathomealone可知鑰匙兒童的最大問題是恐懼。

23.A本題為細節(jié)題。根據(jù)作者在Ordinarily，searchingthroughthefilesforownersofelderlyChevieswouldhavebeenanimpossiblydifficulttask．．．句中所用的虛擬語氣就可肯定A正確。

31.Cso…that…結(jié)構(gòu)，表示“如此……以致于……”。

32.D解析：此處問“當一個緊急情況發(fā)生時，我們將召喚誰”，選疑問代詞who。

33.A上文已經(jīng)提到修車工出題的事，這里再提他另外的事，故應(yīng)選A項。

34.D

35.C解析：slowdown“慢下來”。

36.C解析：本題屬邏輯題。由上文中的“butnotworththousandsofletters”可知，那位歌手的歌曲其實不值得那么多贊美信，故此題應(yīng)用“非贊美性”的單詞。pretty可愛的，crowded擁擠的，wonderful精彩的，均不符。

37.C解析：的確，常常會有這種情況。

38.B解析：本題測試形容詞辨義。valuable意為“有價值的”；essential意為“必要的”；unnecessary意為“不必要的”，而useful意為“有用的”。根據(jù)上下文，應(yīng)該選B。

39.A

40.D解析：一個世紀是一百年的時間。

41.B解析：這篇文章是關(guān)于美國競選的財政改革問題。我們最近聽到最多的政治事件是競選的財政改革。要求改革的人是希望政府為競選付費，或限制候選人和他們的支持者的花銷。

42.A解析：選should，此處譯為“一些人認為警察不應(yīng)該擁有他們既得的權(quán)力”。

43.B解析：通過designingeverything，drawingtheblueprints等等，做了這么多了不起的事情，可以確定B選項great。

44.C解析：這是一篇新聞報道。2006年7月12日，劉翔在洛桑田徑黃金聯(lián)賽中以12秒88的成績打破了由ColinJackon保持了13年之久的世界紀錄。

45.C這里講電視的具體變化。聲音逼真(realistic)。選項B是正確的。

46.A解析：根據(jù)上下文，母親應(yīng)該說她的丈夫確實有一個兄弟。

47.A計算好時間。

48.D解析：通篇講的是電視的變化，這里講的是如今的電視。這里肯定指的是電視屏幕的加大。選項D是正確的。

49.D

50.C解析：save意為“保留，留存”。

51.D解析：選項D畫線字母讀[e]，其他選項畫線字母讀[a:]。

52.C解析：畫線部分讀[u]，其他選項的畫線部分讀[u：]。

53.A

54.B

55.AA項劃線部分發(fā)[e]，而B、C、D三項劃線部分發(fā)[c：]，因此選A項。

57.B3．選項B畫線字母讀[i]，其他選項畫線字母讀[ei]。

62.B時間狀語從句中要用一般現(xiàn)在時表示將來。

63.B解析：“神秘的陌生人”用mysterious。

64.D解析：本句句意是：她變化如此大，我?guī)缀跽J不出她了。

65.A解析：本題測試固定搭配。takenoticeof意為“注意到……”。本句大意為：盡管我對他說過多次，他卻從來不加注意。

66.C解析：thatyougotyesterday是定語從句，修飾scholarship。本題中強調(diào)的是thescholarship…yesterday,所以只能選C。

67.B解析：本題為詞義辨析題。determine意為“決定，確定”；stick意為“區(qū)分，區(qū)別”；identify意為“鑒別，識別”；explore意為“探測，探險”。本句大意為：區(qū)分語法規(guī)則和書面語言的習慣非常重要。

68.D解析：atthesametime“同時”；atatime“一次”；atonetime“曾經(jīng)，一度”；intime“及時；終究”。例如：Icaneatthirtydumplingsatatime.我一次能吃30個餃子。Ilivedinthecou
