The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception is the mind’s interpretation of what the senses in this case our eyes tell us.Many psychologists (心理学家) today are working to try to determine just how a person experiences or perceives the world around him.

    2.In my fridgeless fifties childhood,I was fed well and healthily.The milkman came daily,the grocer,the butcher,the baker,and the ice-cream man delivered two or three times a week.The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes.

    An important contribution made by the invention of the fridge is that_______.
    A:milk,meat,vegetables,etc.were delivered
    B:it has promoted the sales of many kinds of commodities
    C:foods can be preserved
    D:most kids like iced soft drinks
    E:every housewife needs food
    F: the fridge produced when it is working

    答案：B
    解析：
    段首句是观点句，该句说“在我的童年时期还没有冰箱，但是我吃得很好、很健康”，接着提到了“送奶工每天送奶，食品商等每周送两三次货”，在该段最后一句中提到“30年过去了，供货者已经不再送食物（上门）了……”，结合语境不难推断该段中前面部分的主要内容是有关“没有冰箱”时生活情况的描述，因此判断D项没有冰箱的日子是答案。
    段首句是观点句，该句说“冰箱促进了市场梢售“，而“marketing（市场销售）”这个词也是在段落中反复出现，因此判断选项中应该出现与该词相呼应的词或内容，因此判断F项commerce (贸易）与marketing( 销售）呼应，是答案。
    该段段首句很长，但是注意到段首句中出现了由转折词but所引导的转折句（段首句、段末句中的转折分句处的句意往往很可能是段落的主题句），该部分内容说“但是世界上绝大多数的冰箱被发现是用在那些天气温暖、富有的国家里，这些国家从气候上说几乎不必使用冰箱”，借助这部分内容判断E项由冰箱所造成的能源浪费是答案的最佳选项。
    段首句是观点句，该句说“冰箱对环境的影响一直是很显著的（借助常识和背景知识，我们能意识到这里所说‘对环境的影响，是指‘对环境的污染，)，而冰箱给人类所带来的幸福却是微不足道的”，这个句子很明确地反映了作者的观点，对比剩下的被选项，判断B项冰箱所带来的污染是最佳的选项。
    空格所在句子的基本时态（主句时态）是一般过去时，所以空格所在的结构（从句结构）应该是过去时态的一种，所以只有选项A、F可能是答案。由文章第二段第一、二句可知，在20世纪50年代，冰箱开始使用之前，牛奶、肉、蔬菜等食物都会被送上门，所以人们仍然可能获得新鲜的食物。A项最合适。
    由第三段第一句可知，冰箱的发明并没有提供一种新型、经济的方法来保存食物，C项最合适。
    空格前面部分的内容说“冰箱的发明所作出的一个重要的贡献是……”我们在解答概括大意题时，已经了解到“市场销售/贸易”是“冰箱的贡献”，对比剩下的选项，可判断B项冰箱促进了各种商品的梢售是正确答案。
    空格前面部分的内容说“如果你停止使用冰箱，至少你不会被……噪音所影响”。由第五段第二句和第六段最后一句可知噪音是冰箱工作时产生的。由此下项是正确答案。

    The Fridge

Nothing was wasted and we were never troubled by rotten food.Thirty years on,food deliveries have ceased,fresh vegetables are almost unobtainable in the country.
    3. The invention of the fridge contributed comparatively little to the art of food preservation.A vast variety of well-tried techniques already existed-natural cooling,drying,smoking,salting, sugaring,bottling…

    5. Consequently,most of the world's fridges are to be found,not in the tropics where they might prove useful,but in the wealthy countries with mild temperatures where they are climatically al- most unnecessary .Every winter,millions of fridges hum away continuously,and at vast expanse, busily maintaining an artificially-cooled space inside an artificially-heated house-while outside, nature provides the desired temperature free of charge.

    Paragraph 5______
    A: The invention of the fridge.
    B: The pollution caused by fridges.
    C: The widespread need for fridges.
    D: The days without the fridge.
    E: The waste of energy caused by fridges.
    F: The fridge's contribution to commerce.

    答案：E
    解析：
    该段首句（观点句）说“在我小时候的50年代还没有冰箱，但是我吃得很好、很健康”，接着提到了“送奶工每天送奶，食品商等每周几次送货”，在内容上具体说明“没用使用冰箱时的生活情况”，在该段最后一句中提到“30年过去了，食品已经不再送货上门了……”结合该句内容不难推断该段中前面部分的主要内容是有关“没有冰箱”时生活情况的描述，因此判断D（没有冰箱的日子）是正确答案。


    该段首句是观点句，该句说“冰箱的确促进了市场稍售”，而“marketing” (市场销售） 这个词也是在段落中反复出现，因此判断选项中应该出现与该词相呼应的词或内容，因此判断F“commerce” (贸易）与“marketing” ( 4肖售）呼应，故F是正确答案。


    该段首句很长，但是注意到段首句中出现了由转折词“but”所引导的转折句，段首句／段末句中的转折分句处的句意往往很可能是段落的主题句，该部分内容说“但是世界上绝大多数的冰箱被发现是用在那些温度适宜的富有国家里，这些国家从气候上说几乎是没有必要使用冰箱的”，借助这部分内容判断E“由冰箱所造成的能源浪费”是最佳选项。


    该段首句是观点句，该句说“冰箱对环境的影响一直是显而易见的”，借助常识和背景知识，我们能意识到这里所说“对环境的影响”是指“对环境的污染”，而“冰箱对人类幸福所做的贡献却是微不足道的”，这个句子很明确地反映了作者的观点，对比其他选项，判断B“冰箱所带来的污染”是最佳选项。


    空格所在句子的基本时态（主句时态）是一般过去时，所以空格所在的结构（从句结构）应该是过去时态的一种，所以只有A、F可能是答案。从搭配语意“在冰箱开始使用之前，因为牛奶、肉、蔬菜等食物都会送上门，所以人们仍然可能获得新鲜的食物”来看，A为最佳选项。


    从搭配语意“冰箱的发明并没有提供出一种新型的、经济的方法来保存食物”可知， C项最合适。


    空格前面部分的内容说“冰箱的发明所作出的一个重要贡献是……”，我们在解答第24题时，已经了解到“市场稍售／贸易”是“冰箱的贡献”，对比其他选项，判断B项 “冰箱促进了许多种商品的销售”故B项为合适选项。


    空格前面部分的内容说“如果你停止使用冰箱，至少你不会被……噪音所影响”，从搭配语意上看，选择F“当冰箱工作时产生的”最合适。

    The History of the Fridge 1 The fridge is considered a necessity.It has been so since the l960s when packaged food first appeared with the label:"store in the refrigerator." 2 In my fridgeless fifties childhood,I was fed well and healthily.The milkman came daily,the grocer, the butcher,the baker,and the ice-cream man delivered two or three times a week.The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes.Nothing was wasted and we were never troubled by rotten food.Thirty years on,food deliveries have ceased,fresh vegetables are almost unobtainable in the country. 3 The invention of the fridge contributed comparatively little to the art of food preservation.A vast variety of well-tried techniques already existed-natural cooling,drying'smoking'salting'sugaring,bottling… 4 What refrigeration did promote was marketing-marketing hardware and electricity,marketing soft drinks,marketing dead bodies of animals around the globe in search of。good price. 5 Consequently,most of the world's fridges are to be found,not in the tropics where they might prove useful,but in the wealthy countries with mild temperatures where they are climatically almost unnecessary.Every winter,millions of fridges hum away continuously and at vast expense,busily maintaining an artificially-cooled space inside an artificially-heated house-while outside,nature provides the desired temperature free of charge. 6 The fridge's effect upon the environment has been evident,while its contribution to human happiness has been insignificant.If you don't believe me,try it yourself.Invest in。food cabinet（橱柜）and turn off your fridge next winter.You may miss the hamburgers but at least you’ll get rid of that terrible hum.

    Before fridges came into use,it was still possible for people to have fresh foods because______.
    A:milk,meat,vegetables,etc.were delivered
    B:it has promoted the sales of many kinds of commodities
    C:anew,economical way to preserve food
    D:most kids like iced soft drinks
    E:something every housewife needs
    F:produced by the fridge when it is working

    答案：A
    解析：
    第二段主要讲的是在20世纪50年代没有冰箱时作者的童年生涯，那时虽然没有冰箱，但零售商、肉贩、面包师、送冰人等都会送货上门，一周会去两兰次，所以人们既能吃上新鲜的食物，也不会浪费。
    第四段主要讲的是冰箱促进了市场营销，即冰箱对商业的贡献。
    第五段第一句表明，世界上大多数冰箱并不在有其用武之地的热带，而是在几乎不需要它的温带；第五段第二句又表明，冰箱不仅带来了噪音污染，而且没有多大用处。综合起来，这两句同时表明冰箱是对能源的一种浪费。
    第六段最后一句提到冰箱会发出“hum"（嗡嗡声），这是一种噪音污染。本段主要讲的就是冰箱所带来的噪音污染。
    第二段表明，在没有冰箱的年月中，牛奶、肉类、蔬菜等都有专门的商贩派送，所以人们依然能得到新鲜的食物。
    第三段第一句提到，冰箱的发明对食物保鲜的贡献比较小，它保存食物的方法并不新颖、经济，故选C。
    由第四段可知，冰箱对市场营销有促进作用，也就是说，冰箱促进了各种商品的销售。
    第六段最后一句提到，关掉冰箱后，它工作时发出的嗡嗡的噪音也就消失了，故选F。

    What are the three different views on grammar teaching?

    正确答案： The first view is that teaching grammar entails the formal explanation of grammar rules. While learners who receive a great deal of grammatical explanation will end up knowing quite a lot about the language, they will not necessarily be able to put the language to communicative effect. The second view is that teaching grammar is basically a matter of providing learners with practice in mastering common grammatical patterns through a process of analogy rather than explanation. The learners may become fluent in the structures they have been taught, but may not be able to use them appropriately in genuine communication outside the classroom. The third view is that teaching grammar is a matter of giving students the opportunity to use English in a variety of realistic situations. The disadvantage is that learners will not be able to provide explanations of the grammatical rules of the target language.

    The History of the Fridge 1 The fridge is considered a necessity.It has been so since the l960s when packaged food first appeared with the label:"store in the refrigerator." 2 In my fridgeless fifties childhood,I was fed well and healthily.The milkman came daily,the grocer, the butcher,the baker,and the ice-cream man delivered two or three times a week.The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes.Nothing was wasted and we were never troubled by rotten food.Thirty years on,food deliveries have ceased,fresh vegetables are almost unobtainable in the country. 3 The invention of the fridge contributed comparatively little to the art of food preservation.A vast variety of well-tried techniques already existed-natural cooling,drying'smoking'salting'sugaring,bottling… 4 What refrigeration did promote was marketing-marketing hardware and electricity,marketing soft drinks,marketing dead bodies of animals around the globe in search of。good price. 5 Consequently,most of the world's fridges are to be found,not in the tropics where they might prove useful,but in the wealthy countries with mild temperatures where they are climatically almost unnecessary.Every winter,millions of fridges hum away continuously and at vast expense,busily maintaining an artificially-cooled space inside an artificially-heated house-while outside,nature provides the desired temperature free of charge. 6 The fridge's effect upon the environment has been evident,while its contribution to human happiness has been insignificant.If you don't believe me,try it yourself.Invest in。food cabinet（橱柜）and turn off your fridge next winter.You may miss the hamburgers but at least you’ll get rid of that terrible hum.

    An important contribution made by the invention of the fridge is that______.
    A:milk,meat,vegetables,etc.were delivered
    B:it has promoted the sales of many kinds of commodities
    C:anew,economical way to preserve food
    D:most kids like iced soft drinks
    E:something every housewife needs
    F:produced by the fridge when it is working

    答案：B
    解析：
    第二段主要讲的是在20世纪50年代没有冰箱时作者的童年生涯，那时虽然没有冰箱，但零售商、肉贩、面包师、送冰人等都会送货上门，一周会去两兰次，所以人们既能吃上新鲜的食物，也不会浪费。
    第四段主要讲的是冰箱促进了市场营销，即冰箱对商业的贡献。
    第五段第一句表明，世界上大多数冰箱并不在有其用武之地的热带，而是在几乎不需要它的温带；第五段第二句又表明，冰箱不仅带来了噪音污染，而且没有多大用处。综合起来，这两句同时表明冰箱是对能源的一种浪费。
    第六段最后一句提到冰箱会发出“hum"（嗡嗡声），这是一种噪音污染。本段主要讲的就是冰箱所带来的噪音污染。
    第二段表明，在没有冰箱的年月中，牛奶、肉类、蔬菜等都有专门的商贩派送，所以人们依然能得到新鲜的食物。
    第三段第一句提到，冰箱的发明对食物保鲜的贡献比较小，它保存食物的方法并不新颖、经济，故选C。
    由第四段可知，冰箱对市场营销有促进作用，也就是说，冰箱促进了各种商品的销售。
    第六段最后一句提到，关掉冰箱后，它工作时发出的嗡嗡的噪音也就消失了，故选F。

    What are the three different views on grammar teaching?
    The first view is that teaching grammar entails the formal explanation of grammar rules. While learners who receive a great deal of grammatical explanation will end up knowing quite a lot about the language, they will not necessarily be able to put the language to communicative effect. The second view is that teaching grammar is basically a matter of providing learners with practice in mastering common grammatical patterns through a process of analogy rather than explanation. The learners may become fluent in the structures they have been taught, but may not be able to use them appropriately in genuine communication outside the classroom. The third view is that teaching grammar is a matter of giving students the opportunity to use English in a variety of realistic situations. The disadvantage is that learners will not be able to provide explanations of the grammatical rules of the target language.
