A businessman named Milton Levine did.He created the Uncle Milton Ant Farm more than half a century ago.Today，grandchildren of the first ant colony owners are watching ants working hard on the farm.Milton Levine was not trained in the study of insects，also known as entomology.But he knew a lot about ants，and he designed an appealing way to share his knowledge.Mr.Levine began his career as a maker of unusual toys after World War .He had returned to his birthplace in Pittsburgh，Pennsylvania，after serving in the United States military.He got the idea for his future career from a business newsletter，which suggested that the best chances for jobs at the time were in toys.He decided to make toys.They understood that American society was about to change.The huge population increase known as the Baby Boom was beginning.There would be a huge demand for childrens toys.One day，he saw ants parading around a swimming pool.The sight made Mr.Levine remember how much he had liked watching ants as a boy on his uncles farm.Those thoughts gave him the idea for the Uncle Milton Ant Farm.Milton Levine developed a narrow，green plastic container.The top looked like a farm，showing a farmhouse，a barn，a bridge and a windmill (風(fēng)車)Under those images was a divider that separated the antsunderground and above­ground areas.Under that was the sand where people could watch the ants digging passageways.The first Uncle Milton Ant Farms were an immediate success.They were sold in 1956.Two years later，two million of the educational toys had been sold.Through the years the toys continued to attract ant­watchers.People buy Uncle Milton Ant Farms from stores and order from websites.During his life，Mr.Levine saw the sale of more than twenty million of his ant colonies.The Uncle Milton Ant Farm tells far more than how to care for the ants.For example，people receiving an Uncle Milton Ant Farm learn that the little insects are strong.Some can carry loads fifty times heavier than they are.A writer remembers owning an Uncle Milton Ant Farm when he was about five years old.He says he became very good at numbers by counting the ants.5Which of the following words can best describe Milton Levine?AStrong.

I was much hurt.I really wish I could succeed in lose weight in just a few days.But，anyhow，no one have the right to laugh at others whatever beautiful she is.Unit 5The power of nature.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(guān)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(jié)構(gòu)。sb.is said to do意為“據(jù)說某人”，相當(dāng)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(guān)系，且在題干中充當(dāng)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 weeks 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(fēng)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(yīng)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(zhì)”。前三項分別表示“結(jié)果”、“娛樂”、“提交，出示”，都與句意不符。8【解析】選A?？疾閯釉~短語辨析。根據(jù)What a 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?wù)撟闱蛩挤奖恪uit“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 ones attention“吸引某人的注意力”；pay attention to“注意”。11【解析】選A。guarantee “保證；擔(dān)保”。12【解析】選D。句意為：有許多英語教學(xué)方法，但它們不一定都對中國學(xué)生同樣有效。A項應(yīng)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。考查動詞辨析。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。句子的主語we和arrive之間為主謂關(guān)系，故用arrive的現(xiàn)在分詞形式?，F(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。.閱讀理解【解題導(dǎo)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的“To get the wished­for effect”相呼應(yīng)，由此可推斷其意思是“達到預(yù)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(nèi)容可知蛋白質(zhì)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(nèi)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(nèi)容可知最佳標題是“吃出好心情”?！窘忸}導(dǎo)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(shè)計玩具Uncle Milton Ant Farm的相關(guān)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(xué)”之意。根據(jù)常識可知只有butterflies(蝴蝶)屬于昆蟲，會在昆蟲學(xué)中學(xué)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 population increase known as the Baby Boom was beginning.There would be a huge demand for childrens 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(wù)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.”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。.短文改錯Im 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?
