56、”；brand意為“品牌；牌子”；condition意為“條件；狀況”；style意為“樣式；款式”。根據“只有我們店賣這條連衣裙”可知，這條連衣裙“款式”特別，故選D。 24.

B。本小題考查系動詞詞義辨析及語態(tài)。taste意為“嘗起來”；smell意為“聞起來”，應答者還沒有吃魚，只是認為“聞起來”美味，因此先排除選項A和C。表示感受、感官的系動詞feel, sound, taste, smell等常用其主動形式表示被動意義，故選B。 30

59、. D。本小題考查動詞的語態(tài)及時態(tài)。主語A new club是動詞start(創(chuàng)辦)的承受者，因此用被動語態(tài)；由at the beginning of this year可知用一般過去時的被動語態(tài)，故選D。 31. B。本小題考查主謂一致和動詞的時態(tài)。the number of ...?意為“……的數量；……的數目”，作主語時，謂語動詞應用單數形式，由此可先排除選項A和C；由題干后半句中的is (一般現在時)可知，前半句也用一般現在時，故選B。 32. C。本小題考查固定句型。It is said that ...?意為“據說……”，故選C。 33. B。本小題考查短語辨析。by acc

61、n意為“真有趣”；I agree意為“我同意”；with pleasure意為“很樂意效勞”，用來表示愿意為某人做某事。發(fā)話者想讓對方幫忙在網上找一首歌，對于發(fā)話者的請求，出于禮貌，應答者表示“愿意效勞”，故選D。 ? 完形填空： 【體裁】記敘文 【話題】科普知識與現代技術 【大意】材料講述了一位發(fā)明人克服困難、在事業(yè)上獲得成功的故事。 36. B。由第三段第三句中的that would help children learn to swim可知鯊魚鰭是用來幫助兒童學習“游泳”的。 37. B。由下一句中的On the show可知凱文參加了一檔“節(jié)目”。 38. D。由此空后

62、面的his idea was dangerous and they even made a couple of jokes可知一些人“提醒”了他。 39. A。由上一句及本句中的a?“silly”?thing可知他們說“沒人”會買。 40. C。后半句(“我”不是個商人)是前半句(“我”參加節(jié)目)的原因，所以用because連接。 41. C。由第二段首句中的for investment(投資)可知凱文需要“錢”。 42. A。由第一段第三句中的came up with the idea of creating a shark fin可知凱文認為自己有個好“產品”。 43. B。由第

63、二段可知沒有人愿意給凱文投資，由此推斷此處是指凱文決定自己“獨自”繼續(xù)這個項目。 44. D。凱文“為”新生意籌措了大約20萬英鎊。 45. D。由上下文可知他的產品很受“歡迎”。 ? 閱讀理解： B 【體裁】記敘文 【話題】日常活動 【大意】材料講述了Johanna去農場采摘草莓的故事。 56. D。本小題考查學生理解具體信息的能力。由第一段第三、四句可知上周六Johanna第一次去農場采摘草莓。 57. B。本小題考查學生理解具體信息的能力。由第二段可知讓Johanna吃驚的是草莓不是長在樹上或灌木上，而是長在類似藤的一種東西上。 58. C。本小題考查學生理解具體信

64、息的能力。由第三段最后兩句可知Johanna認為農場的草莓又大又甜。 59. B。本小題考查學生理解具體信息和簡單計算的能力。由第四段第二句可知付款時Johanna給了農場主一張10美元的鈔票，農場主給她找了1美元，由此可知她花了9美元。 60. A。本小題考查學生歸納段落大意的能力。最后一段最后一句是該段的主旨句。該段主要講了Johanna打算如何處理從農場采摘來的草莓，如制作果醬、直接吃或蘸白糖吃或冷凍起來以后用等。 ? C 【體裁】說明文 【話題】科普知識與現代技術 【大意】材料介紹了電視機及一些相關產品的發(fā)展歷史。 61. C。本小題考查學生理解具體信息的能力。由第一段

65、第四句可知C項正確。 62. D。本小題考查學生理解具體信息和簡單計算的能力。由第一段第三句可知VCR于1977年出現在美國，另由該段倒數第二句可知DVD于1997年首次出現在美國，由此可知DVD比VCR晚出現了20年。 63. D。本小題考查學生理解具體信息的能力。第二段主要介紹了一項新發(fā)明——TiVo，由第二段第一句中的machines that had memory可知TiVo是帶有記憶功能的。 64. A。本小題考查學生根據上下文猜測詞義的能力。有了記憶功能，電視機就能像電腦一樣“存儲”電影。 65. A。本小題考查學生理解具體信息的能力。由最后一段第二句可知作者認為不論在家看

66、電影還是去影院看電影都很棒，因此A項正確。 ? 綜合填空： 【體裁】說明文 【話題】安全與救護 【大意】材料介紹了鱷魚襲擊人類的一些事件。 76. quickly。由第二段最后一句中的suddenly come out of a river和about 17 kilometers in an hour on land可知鱷魚的攻擊速度非?！翱臁薄Ｐ揎梽釉~attack，所以用quick的副詞形式。 77. them。它們將動物或人類拖入水中并殺死“它們?/?他們”。作動詞的賓語要用代詞的賓格形式。 78. run。它們在陸地的“奔跑”速度可以達到每小時17公里。 79. humans。由下面列舉的例子可知在澳大利亞每年都會發(fā)生鱷魚襲擊“人類”的事件。 80. died。由本段第四句可知兩年前一個24歲的德國游客在湖里游泳時“死”了。事件發(fā)生在過去，所以用die的過去式形式。 81. Although。前半句(有標志牌警告此處有鱷魚)和后半句(這個女孩和她的朋友決定半夜去游泳)在語義上構成轉折關系，所以用although連接。 82. found。女孩突然消失了，第
