At downtown shopping mall Central World Plaza，Thais put away their credit cards for a moment to consider their energy consumption，as lights dimmed.“I waste a lot of energy at home，for example，I turn my television on while spending two hours on the Internet，” said an 18-year-old student.“From now on，I will turn off the TV.” There was only partial darkness in Bangkok’s central shopping district，with some malls and hotels ignoring the request，but it was enough to make business owner Somas Thanyatote think about his energy habits. “I will turn off the air conditioner and use the electric fan or open the windows instead，” the 58-year-old told AFP. “Street lights and other security-related lighting remained on and there will also be more police on duty in case that crimes increased.” Governor Apirak Kosayedhin said. Bangkok，a city with a population of 12 million，spews more than 26 million tons of carbon dioxide into the air each year，or nearly 20 percent of Thailand’s total CO2 emissions. Bangkok’s lights-out campaign included a public screening in a downtown shopping district of the Oscar-winning documentary “An Inconvenient Truth” by former US vice-president Al Gore. Australian city Sydney held a similar exercise in April，with a one-hour blackout observed by 65,000 homes and 2,000 businesses，which organisers estimated cut normal energy use by 10 percent. 1．Which of the following can be the best title for the passage? A．A Power Failure in Bangkok B．Bangkok’s Campaign to Remind Its Residents of Global Warming C．People’s Attitudes toward Global Warming D．Carbon Dioxide—the Major Factor of Global Warming 2．How many tons are the total CO2 emissions of Thailand? A．12 million tons. B．26 million tons. C．60 million tons. D．130 million tons. 3．From the passage we can infer that________. A．a(chǎn)ll the people in Bangkok would use the electric fan or open the windows instead of air conditioners to save energy B．the campaign in Bangkok also raised awareness of Sydney’s residents C．not all the residents were in favor of the campaign D．there were 6 cities taking part in the campaign that took place in Thailand 4．Which action of the following was not taken by Bangkok government? A．People would be fined if they didn’t switch off their lights. B．Extra police were on duty for fear that more crimes increased. C．2,000,000 of the city’s residents were requested to join in switching off non-essential lights. D．A public screening was set up in public to make people enjoy a film by a former US vice-president. tend vi.趨向；易于；走向 生義：vt. & vi.照顧；護(hù)理 His views tend towards the extreme. 他的觀點(diǎn)趨于偏激。 He tends to get angry when people oppose him. 別人反對(duì)他的意見時(shí)，他很容易生氣。 Doctors and nurses were tending (to) the injured in the earthquake. 醫(yī)生和護(hù)士正在護(hù)理地震中的受傷者。 【答案解析】 Period One　Warming Up & Reading Ⅰ.1.to　to　2.about　3.to　in　to　of　like　4.of 5．of　to　6.in　up　to　7.in　8.towards　9.On 10．On　to　about　in Ⅱ.1.毫無疑問，地球是在變暖，而且全球轉(zhuǎn)暖是人為的，而不是隨意的自然現(xiàn)象。　(1)There is no doubt that the price of wheat will go up.　(2)It was a key that I found in his pocket. 2．所有的科學(xué)家贊同這種觀點(diǎn)：人們?yōu)榱松a(chǎn)能量而燃燒化石燃料(如煤、天然氣和石油等)，從而引起了地球溫度的升高。　(1)We don’t subscribe to the view that we have failed.　(2)that he won a scholarship 3．如果沒有這種‘溫室效應(yīng)’，地球的溫度將比現(xiàn)在的溫度還要低33攝氏度左右?！?1)Without electricity，life would be quite different today.　(2)Without your help，I wouldn’t have succeeded anyway. 4．即使我們開始減少二氧化碳和其他溫室氣體的含量，在未來的幾十年或幾個(gè)世紀(jì)內(nèi)，氣候仍會(huì)持續(xù)轉(zhuǎn)暖。 (1)Even if (I am) invited　(2)even if the weather is bad Ⅲ.1.D　[句意為：溫室里面的空氣是暖和的，因?yàn)椴Ａ苁箒碜躁柟獾臒崃苛糇〔⒆柚顾魇А 2．A　[在表示時(shí)間、地點(diǎn)、條件等的狀語從句中，如果主句的主語和從句主語一致，且從句謂語含有動(dòng)詞be時(shí)，可省略從句的主語和be動(dòng)詞。因compare與主語之間是被動(dòng)關(guān)系，故此處的完整形式為：when it is compared to other changes。] 3．C　[句意為：全球轉(zhuǎn)暖是人為的，而不是隨意的自然現(xiàn)象。rather than而不是，符合題意。more than多于，超過；other than除了；except for除了(用于肯定主體，否定局部)。] 4．D　[考查強(qiáng)調(diào)句型，it is/was...that/who...，當(dāng)強(qiáng)調(diào)人時(shí)，可用that或who。此處強(qiáng)調(diào)主語a scientist called Charles Keeling。] 5．D　[第一空用subscribe to表示“同意，贊成”；第二空用不定式表目的。apply to申請(qǐng)，應(yīng)用于；correspond to符合，與……一致；cater to滿足于；迎合。] 6．C　[the most important one of...是一個(gè)非限制性定語從句，修飾先行詞“greenhouse” gases。因先行詞是物，故排除B項(xiàng)；that和these不能用于引導(dǎo)非限制性定語從句。] 7．B　[句意為：這意味著更多的熱能將被困在大氣層中，從而引起了全球氣溫上升。go up上升，增長(zhǎng)，符合題意。grow up成長(zhǎng)，長(zhǎng)大；build up增進(jìn)；加強(qiáng)；bring up養(yǎng)育，撫養(yǎng)。] 8．A　[句意為：正是由于越來越多的燃燒化石燃料導(dǎo)致了二氧化碳的增加。result in導(dǎo)致，符合題意。lead to導(dǎo)致；result from由……引起，因……而產(chǎn)生；as a result因此，結(jié)果，在句中作狀語。] 9．B　[be opposed to反對(duì)，符合題意。object to反對(duì)；be supposed to do sth.應(yīng)該做某事；be determined to do sth.決心做某事。] 10．A　[even if即使，縱然，符合題意。as if好像；now that既然；as long as只要。] Ⅳ.1.B　[主旨大意題，綜觀全文可以看出，文章開篇點(diǎn)題，在第一段點(diǎn)明了文章的主題：泰國(guó)首都曼谷(Bangkok)為了提高人們對(duì)全球變暖的認(rèn)識(shí)在周三關(guān)燈15分鐘。然后下文對(duì)這一活動(dòng)的情況作了詳細(xì)的介紹，故選B項(xiàng)。這里要注意題目和原文中同義詞的替代問題：raise awareness＝remind...of。] 2．D　[計(jì)算題。由倒數(shù)第三段的“...more than 26 million tons of carbon dioxide into the air each year，or nearly 20 percent of Thailand’s total CO2 emissions.”可以計(jì)算出泰國(guó)整個(gè)二氧化碳的排放量是130 million tons。] 3．C　[推理判斷題。由文章第三段中描述的“...with some malls and hotels ignoring the request...”可知，并不是所有的人都贊成這次活動(dòng)。] 4．A　[細(xì)節(jié)判斷題。用排除法。由第一段可以判斷C項(xiàng)正確；由倒數(shù)第二段可以判斷D項(xiàng)正確；由倒數(shù)第四段可以判斷B項(xiàng)正確。文章沒有提到不關(guān)燈的市民要被罰款(be fined)。] Period Two　Language Points Ⅰ.語境填詞 1．When I’m tired，I t________ to make mistakes. 2．Don’t throw waste paper at r________ or you will be punished to be on duty again. 3．By the sea I saw a wide r________ of seashells. 4．This company pays more attention to quality than to q________. 5．Most air pollution is caused by the burning of f________ like coal，gas and oil. 6．He gave a ________ (一瞥) at his watch and then looked at the sky. 7．I ________ (反對(duì)) your going there alone. 8．We are making slow but ________ (平穩(wěn)的) progress in our English. 9．Recently we have seen a gradual ________ (傾向) towards healthier food. 10．The ______________ (結(jié)果) was that many people were overweight.
