1、Unit 4 Global warming 課時作業(yè) Ⅰ.閱讀理解 A (2019·山師附中模擬)Sometimes we may find that every week there are a lot of new stories about how climate change is affecting the planet，or new plans to battle its effects.But the concept itself isn't new at all—in fact，scientists have been exploring questions about

2、 climate change for almost 200 years. The idea of “greenhouse gases” goes back to 1824，when Joseph Fourier wondered what was regulating the earth's temperature.Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a gl

3、ass lid.As light shines through the glass，the inside gets warmer as the lid traps the heat.As Fourier's ideas spread，it came to be called “the greenhouse effect”． Scientists continued to study the greenhouse effect.Not until a Swedish chemist named Svante Arrhenius came along，did scientists underst

4、and how global warming actually works.After years of work，Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct effect on global temperatures. Arrhenius found that CO2，and other gases trap radiation，which warms the atmosphere.Arrhenius was the first to su

5、spect that burning coal could contribute to the greenhouse effect.But Arrhenius welcomed the warming effect on the planet.At a lecture later that year，Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”． While Arrhenius' findings won him

6、the 1903 Nobel Prize in chemistry，scientists kept debating whether the greenhouse effect was increasing until 1950，when researchers finally began to find strong data supporting it.By the end of the 1950s，American scientists had been sounding the alarm on the long－term consequences of climate change.

7、Climate change research has come a long way since Fourier first described the greenhouse effect－still，maybe Arrhenius should have been more careful of what he wished for. 【文章大意】　本文主要講述了科學家們對氣候變化的眾多探索。200年來科學家們一直在探索氣候變化的問題。溫室效應(yīng)這個觀點的提出可以追溯到1824年。瑞典化學家Arrhenius是第一位質(zhì)疑燃燒煤會增加溫室效應(yīng)的人，并且在1903年獲得諾貝爾化學獎。 1．W

28、 in road safety and resuscitation. 【語篇解讀】　本文是夾敘夾議文。作者結(jié)合自己遭遇暴力脅迫的經(jīng)歷，極力強調(diào)學校開設(shè)女生自衛(wèi)課程的意義，大聲呼吁學校要對廣大女學生進行自衛(wèi)教育。 1．A.never　　　　　　　B．ever C．forever D．however 【答案】　A　與第二段第一句中I know及轉(zhuǎn)折詞however對應(yīng)，選A合適。 2．A.thief B．man C．robber D．prisoner 【答案】　B　由第二段第二句中．...a man attacks her...可知選B。 3．A.takes B．pushe

29、s C．drags D．hits 【答案】　C　這里是設(shè)想一個犯罪場景，與grabs，holding a knife to your throat對應(yīng)，自然是drags合理，意為“用力拖、拽”。hits不能同from a path，into a park搭配，故D不可選。 4．A.when B．how C．why D．what 【答案】　D　這里指“我”的確知道作為那個女孩子感覺是什么樣的。 5．A.before B．a(chǎn)fter C．a(chǎn)s D．until 【答案】　C　這里是as引導時間狀語從句。 6．A.so B．because C．so that D．be

30、cause of 【答案】　B　這里是because引導原因狀語從句。 7．A.attcak B．conflict C．fight D．event 【答案】　A　上下文都出現(xiàn)了attack一詞，也是全文的關(guān)鍵詞之一。event通常指“重大的事件”，與文章情境不符。 8．A.took place B．took the place C．took control D．took charge 【答案】　A　攻擊是發(fā)生在“我”遛過狗的公園。B、C、D分別意為“取代，代替”；“控制”；“負責”，與句意不符。 9．A.replied B．objected C．pointed D

31、．responded 【答案】　D　面對攻擊，“我”的反應(yīng)是保持冷靜。respond to“對某事作出回應(yīng)、答復”。 10．A.off B．out C．down D．back 【答案】　A　“我”又抓又叫，使他沒有得逞。fight sb.off“擊退，阻止”；fight back“還擊”，后接賓語要用fight back against sb./sth.；fight down“抑制住，不流露”；fight out“決出勝負，辯論出結(jié)果”，B、C、D均不符合文意。 11．A.consideration B．hesitation C．doubt D．trouble 【答案】　

32、C　“我”敢肯定地說“我”上高中時所學的自衛(wèi)課程幫了“我”大忙，使“我”免受傷害。表示“毫無疑問”可以說without doubt，也可以說without a doubt；consideration“思索”或hesitation“猶豫”在此處不準確，且其前也不可用不定冠詞。 12．A.taught B．helped C．protected D．told 【答案】　B　此處．...to escape without being hurt.表示結(jié)果，與teach搭配起來不合邏輯；protect用于protect sb.(from)doing sth.結(jié)構(gòu)；told沒有helped貼切，故

33、B正確。 13．A.reporting about B．talking about C．knowing about D．worrying about 【答案】　B　這里指在課堂上，學生們討論這一情景，再分角色模擬這一情景。 14．A.rights B．books C．knowledge D．strength 【答案】　C　這里指通過自衛(wèi)課程，“我”學到了關(guān)于這一方面的知識。 15．A.hear B．witness C．solve D．experience 【答案】　D　在澳大利亞，每年大約有10萬女性會遭受到性侵。只有D能表示“遭受”這一含義。 16．A.nee

34、ded B．took C．used D．spent 【答案】　D　本題為spend time doing sth.結(jié)構(gòu)。句意為：如果學校用來教育年輕女孩自衛(wèi)的時間跟他們來培訓(急救)復蘇的時間一樣多的話。 17．A.improve B．love C．respect D．defend 【答案】　D　此處作者講述的是self－defence course，故D正確。 18．A.acceptable B．large C．different D．stable 【答案】　C　如果是這樣的話，這些數(shù)據(jù)可能會大不一樣。作者的意思是遭受到性侵的婦性會大大減少。A、B、D與作者的意思

35、相矛盾。 19．A.particularly B．hopefully C．easily D．generally 【答案】　A　通過把“我”的這次經(jīng)歷講出來，“我”特別想表示支持自衛(wèi)教育有重大價值這一說法。從文章第三段開始，這一直就是作者所強調(diào)的問題，故選A“格外，特別”，以示強調(diào)。 20．A.interesting B．perfect C．important D．normal 【答案】　C　上句談到the value of learning self－defence，上文作者又結(jié)合自身經(jīng)歷談到了自衛(wèi)課程起到的作用，故此處意為“這些自衛(wèi)課程的確同公路安全課程和復蘇課程一樣重要
