Unit 5　The power of nature Ⅰ.單項填空 1．【解析】選A。根據(jù)讓步狀語從句中的“目前還看不到任何明顯的危險”可知，批評家們認為這家工廠對環(huán)境有潛在威脅。imaginable假想的，想象中的；uncertain不確定的，無把握的；immediate立

29、即的，立刻的。 2．【解析】選D。此句中explain與其邏輯主語即主句主語I之間是主謂關系，且該動作發(fā)生在主句謂語動作之前，故用其動詞-ing形式的完成式。 3．【解析】選A。本題考查sb.is said to do結構。sb.is said to do意為“據(jù)說某人……”，相當于It is said that...；根據(jù)題意，說明他已經(jīng)離開舞臺了，所以用sb.is said to have done。 4．【解析】選D。由于是主語在等待，表主動關系，且在題干中充當方式狀語。動詞不定式不作方式狀語，所以用現(xiàn)在在分詞表主動和伴隨。had an anxious couple of week

30、s waiting for...在焦急中等待……的幾周。 5．【解析】選B。考查冠詞。equipment為不可數(shù)名詞，且此處表示泛指，故不用冠詞；mayor表示職位，頭銜且作賓補也不用冠詞。 6．【解析】選C。考查固定句式。It is no use doing sth.“做……是沒有用的”。句意為：在臺風離開前評估全部損失是沒有用的。 7．【解析】選D?？疾槊~辨析。句意為：按照我們校長的觀點，應該鼓勵所有的兒童充分發(fā)揮他們的潛能。potential表示“潛力；潛質”。前三項分別表示“結果”、“娛樂”、“提交，出示”，都與句意不符。 8．【解析】選A。考查動詞短語辨析。根據(jù)What a

31、 mess！可推測，“我正翻抽屜尋找那件毛衣”。故go through“翻找”符合語境。glance through“瀏覽”；break through“突圍”；get through “通過，(電話)接通”。 9．【解析】選A?？疾閯釉~辨析。既然是David最喜歡的運動，那么任何時間與他談論足球他都方便。suit“適合”符合語境。 10．【解析】選D。when并列連詞，常用于“...be about to do sth.when...”句型中，表示“正要……這時……”。attract/draw one’s attention“吸引某人的注意力”；pay attention to“注意……

32、”。 11．【解析】選A。guarantee “保證；擔?！薄? 12．【解析】選D。句意為：有許多英語教學方法，但它們不一定都對中國學生同樣有效。A項應說成a variety of；B項意為“準確的，精確的”；C項意為“原始的”；D項意為“不同的，多種多樣的”。由句意可知選D。 13．【解析】選B?？疾閯釉~辨析。語意表示“對他在公共生活中的成功起到了極大的促進作用”，故用contribute to表示“有助于，是……的原因之一”。owe to表示“歸功于，欠(債、情等)”；attach to表示“附上”；relate to表示“涉及，了解”。 14．【解析】選A?？疾榉侵^語動詞。句子的

33、主語we和arrive之間為主謂關系，故用arrive的現(xiàn)在分詞形式。現(xiàn)在分詞短語Arriving at the party在這里作時間狀語。句意為：到了宴會上，我看到Ruth一個人站在大廳的一角。 15．【解析】選D?？疾榻浑H用語。根據(jù)答語的下一句可知答話人“還沒有”完成。not yet表示“還沒”。前三項分別表示“根本不”、“不大可能”、“一點兒也不”，都與語意不符。 Ⅱ.閱讀理解 【解題導語】　信不信由你，一些食物確實能夠改變我們的心情。如果你的心情不好，可以通過吃來解決。有哪些食物可以改變我們的心情呢？讓我們一起來看這篇文章吧！ 1．【解析】選C。猜測詞義題。此處與本段開頭部分

34、的“To get the wished-for effect”相呼應，由此可推斷其意思是“達到預期效果”。 2．【解析】選B。細節(jié)理解題。根據(jù)第二個標題中的內容可知蛋白質的功能是讓你精力充沛。 3．【解析】選A。推理判斷題。根據(jù)第三個標題第一句中的內容可知脂肪和糖能極大地幫助人們感覺高興。 4．【解析】選A。主旨大意題。第一段的最后一句是本文的中心句，根據(jù)本句的內容可知最佳標題是“吃出好心情”。 【解題導語】　本文介紹了Uncle Milton Ant Farm (螞蟻農(nóng)場玩具)的發(fā)明者Milton Levine。 5．【解析】選B。推斷題。從他設計玩具Uncle Milton An

35、t Farm的相關信息可以看出他極具創(chuàng)新精神。 6．【解析】選B。推斷題。根據(jù)第一段中的“Milton Levine was not trained in the study of insects，also known as entomology.”可知，entomology是“昆蟲學”之意。根據(jù)常識可知只有butterflies(蝴蝶)屬于昆蟲，會在昆蟲學中學到，故B項正確。 7．【解析】選D。細節(jié)理解題。根據(jù)第二段中的“He got the idea for his future career from a business newsletter.”“The huge populati

36、on increase known as the Baby Boom was beginning.There would be a huge demand for children’s toys.”以及第三段中的“...he saw ants parading around a swimming pool.”等信息可知，他從商務通訊、嬰兒潮及螞蟻搬家中得到啟發(fā)，發(fā)明了這個螞蟻農(nóng)場玩具。D項沒有提到。 8．【解析】選C。段落大意題。根據(jù)最后一段的中心句“The Uncle Milton Ant Farm tells far more than how to care for the ants.

37、”可知，本段主要講這個螞蟻農(nóng)場玩具除了告訴大家怎么去照顧螞蟻外，還有更深層的教育功能。 Ⅲ.短文改錯 I’m middle school student，I like to make with people and always try my best to get along with them. last week I happened to hear one of my speaking ill of me with others behind my back， made me very sad.She said I was fat and acted as stupid as a bear.I had been kind to her，but why did she at my appearance?
