【文章內(nèi)容簡介】 a hot topic here at MNN: the airpurifying qualities of the mon house plant. Given that the air inside your home can be 2 to 5 times more polluted than the air outside of it, making it clean with plants like peace lily (百合花) and asparagus fern (蘆筍蕨) is an economical artistically pleasing alternative to air purifiers. So it39。s been acknowledged that a bunch of pretty putted houseplants can help you maintain a healthier home, but a smarter home? That39。s the question in light of a recent study published by the Journal of Environmental Psychology showing that the presence of plants in a room, particularly in an office environment, can shrink attention span (范圍). Struggling directive attention (the kind of attention that takes effort) can be refreshed through exposure ho to naturalistic environments. Basically, taking a walk through the park can clear one39。s head. But can a head be refreshed simply by being surrounded by houseplants? To test their theory, the study39。s authors rounded up a bunch of participants, put some of them in a mom with no plants and put others in a room with our plants placed around a desk, and put them all to the same series of tests. First was a Rearing Span Teat which involves reading a series of sentences aloud and remembering the Last word in each sentence. This task requires that you fluently switch between attention demanding tasks: from rending and memorizing at one moment to writing and recalling at the next. Next came a proofreading task fallowed by another Reading Span Test. The results? Participants working in the room with the plants improved their performance from the first Reading Span Test to the second while those working in the room lacking in greenery did not. Consequently, the benefits of working among plants is indeed evident.（1）What do we know from the first paragraph? indoors can help avoid the poorer air outdoors. can Function as beautiful cheap air purifiers. polled flowers as decorations is very interesting. purifiers are the most effective to create a healthy home.（2）What does the underlined part in paragraph 2 probably refer to? one39。s attention. one39。s attention. one39。s attention. one39。s attention away.（3）What does the test prove? in nature helps increase productivity. will be in great demand in our life. creates healthier naturalistic atmosphere indoors. among houseplants improves mental functioning.（4）What can be a suitable title for the text? : Grand Feast to Eyes: Effective Airpurifier: Visual Brain Food Plants: Great! Housebeautifier【答案】 （1）B（2）A（3）D（4）C 【解析】【分析】本文是一篇說明文，通過實驗說明室內(nèi)植物可以很好地提高人們的注意力。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“Given that the air inside your home can be 2 to 5 times more polluted than the air outside of it, making it clean with plants like peace lily (百合花) and asparagus fem (蘆筍蕨) is a economical, artistically pleasing alternative to air purifiers.”可知，鑒于室內(nèi)空氣污染比室外空氣污染嚴(yán)重2到5倍，用百合花、蘆筍蕨這些植物來取代空氣凈化器凈化室內(nèi)空氣即經(jīng)濟(jì)實惠又美觀。故選B。 （2）考查詞義猜測。根據(jù)第二段中的“Struggling directive attention(the kind of attention that takes effort can be refreshed through exposure to naturalistic environments.”可知，掙扎的注意力(需要努力的注意力)可以通過置身于自然環(huán)境中來恢復(fù)。據(jù)此可推知，縮小注意力范圍即指注意力得到恢復(fù)，變得更專注。故選A。 （3）考查細(xì)節(jié)理解。根據(jù)第四段中的“Participants working in the room with the plants improved their performance from the first Reading Span Test to the second while those working in the room lacking in greenery did not. Consequently, the benefits of working among plants is indeed evident.”可知，在有植物的房間里工作的參與者從第一次閱讀廣度測試到第二次閱讀廣度測試的成績都有所提高，而在沒有綠色植物的房間里工作的參與者則沒有。因此，在植物間工作的好處是顯而易見的。由此可知，這個測試的證實了在室內(nèi)植物間工作可以改善精神功能。故選D。 （4）考查主旨大意。根據(jù)全文內(nèi)容可知本文介紹室內(nèi)植物可以很好地提高人們的注意力，對大腦的工作效果起到積極作用。故選C。 【點評】本題考點涉及細(xì)節(jié)理解，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。5．閱讀理解 A new study shows that air pollution can cause a huge reduction in our intelligence. The study was a project involving researchers at Peking University in China and Yale University in the United States. The researchers reported that longterm exposure to air pollution can affect a person39。s mental abilities in two areas: Language and math. The researchers studied about 25,000 people from across China. Between 2010 and 2014, these Chinese men, women and children were given language and math tests. Then researchers pared the test results with measurements of pollution in the air, namely nitrogen dioxide and sulfur dioxide (二氧化硫). Xi Chen of the Yale School of Public Health led the study. He and his team found that breathing polluted air can reduce a person39。s education level by about one year. Chen said that the effect generally is worse for those over 64 years of age, for men and for those with little or no education. “The older persons—they are more affected. And we find, quite amazingly, males are more affected than females. And people working outdoors are more affected than people working indoors. He noted that the youngest people in the study were 10 years old, while the oldest was 90 years old. They came from China39。s 33 provinces. In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample. The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution or humans will face a bad situation.（1）What is the result of the study? pollution has a bad effect on people39。s intelligence. are more affected by air pollution than males. are more affected by air pollution than Chinese. working indoors are actually not affected by air pollution.（2）What did Chen say about the study? is doubtful. is extremely unfair. is mon and not representative. is relatively objective and persuasive.（3）What did the researchers emphasize in the last paragraph? data from the 33 provinces is convincing. whole world should pay attention to air pollution. less educated take more responsibility for air pollution. pollution39。s influence on verbal ability is less serious as people age.（4）Where is the text most likely taken from? life diary. guidebook. science magazine. biography.【答案】 （1）A（2）D（3）B（4）C 【解析】【分析】本文是一篇說明文，一項新的研究表明，長期暴露在空氣污染中會在語言和數(shù)學(xué)兩個方面影響一個人的智力，因此每個國家都應(yīng)關(guān)注空氣污染否則人類將面臨一個糟糕的局面。 （1）考查細(xì)節(jié)理解。根據(jù)第二段中的“The researchers reported t
