section grammar.閱讀理解athe plan：turn the mars into a blue world with streams and green fields, and then fill it with creatures from the earth.this idea may sound like something from science fiction, but it is actually being taken seriously by many researchers.this suggests the future for the “red planet” will be the main topic for discussion at an international conference hosted by nasa this week. leading researchers as well as science fiction writers will attend the event. it comes as nasa is preparing a multibilliondollar mars research programme.“turning the mars into a little earth has long been a topic in science fiction，”said dr.michael meyer, nasas senior scientist. “now, with scientists exploring the reality, we can ask what are the real possibilities of changing the mars.”most scientists agree that the mars could be turned into a little earth, although much time and money would be needed to achieve this goal. but many experts are shocked by the idea.“we are destroying our own world at an unbelievable speed and now we are talking about ruining another planet，” said paul murdin from the institute of astronomy, cambridge, uk.over the past months, scientists have become increasingly confident they will find martian life forms. europe and americas robot explorers have found the proof that water, mixed with soil, exists in large amounts on the planet.in addition, two different groups of scientists announced on march 28 that they had found signs of methane (甲烷) in the martian atmosphere; the gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planets soil.but scientists such as dr.lisa pratt, a biologist at indiana university, say that these microbes will be put in danger by the little earth project.“before we have even discovered if there is life on the mars, we are talking about carrying out projects that would destroy all these native life forms, all the strange microbes that we hope to find buried in the soil，” said dr. pratt.monica grady, a planetary scientist at the natural history museum, london, shares this view.“we cannot risk starting a global experiment that would wipe out the precious information we are looking for，” she said. “this is just wrong.”【語篇解讀】本文是一篇科普說明文。在太空開拓人類新的生存領(lǐng)地一直是科幻小說的主題，也是人類一直希望實(shí)現(xiàn)的夢想。如今，美國的一部分科學(xué)家想把紅色火星改造成藍(lán)色的“生命天堂”。就這一提議科學(xué)家們展開了討論。1the passage is about .aa plan turning the mars into a little earthbthe necessity of changing the marscfinding water on the marsdthe mars supporting life解析：選a主旨大意題。由第一段可以看出，人們計(jì)劃將火星變?yōu)橐粋€(gè)小地球。后文就這一計(jì)劃是否應(yīng)該實(shí)施進(jìn)行了探討。故文章是圍繞將火星變?yōu)樾〉厍蜻@一話題展開的。2why is dr. lisa pratt against the plan?awater has been found on the mars.bit will cost too much money and work.cthe native life forms on the mars would be destroyed.dthe earth is being destroyed at an unbelievable speed.解析：選c細(xì)節(jié)理解題。由倒數(shù)第三段中的“. these microbes will be put in danger by the little earth project.”可知，莉薩博士反對該計(jì)劃的原因是擔(dān)心火星上的微生物會(huì)受到破壞。3what could prove the existence of microbes living in the mars soil?aliquid water on the mars.bsome creatures on the mars.ca lot of good soil on the mars.dsigns of methane in the mars atmosphere.解析：選d推理判斷題。由倒數(shù)第四段可以看出，科學(xué)家在火星上發(fā)現(xiàn)了甲烷，而甲烷是生物排放出的一種氣體。由此科學(xué)家認(rèn)為火星上有生物存在。4we can infer from the passage that .awater is a key factor for life; without it, living on the mars would be impossiblebthe project wont affect the native life forms supposed to live on the marscthe idea turning the mars into a little earth is nothing but science fictiondmonica grady is in favour of carrying out the little earth project解析：選a推理判斷題。由倒數(shù)第五段可知，科學(xué)家對于能夠在火星上發(fā)現(xiàn)生物非常有自信，因?yàn)闅W洲和美國的機(jī)器人已經(jīng)發(fā)現(xiàn)了水存在的證據(jù)。由此我們可推知，水是生命存在的重要因素。bmy cellphone rang while i was working on my computer. i looked at the phone and saw it was my 17yearold son, tom. i quickly picked it up. “mom, i got a 71 on the test. i did it.” with those few words, i could feel my heart start to pound.living in new york state, students cannot graduate from high school unless they pass at least five exams: one in english, one in science, two in history and one in math. for most students, who work hard, attend class, and do their homework, it isnt that hard. but for tom, who is dyslexic (朗讀困難的), it is such a real challenge that some teachers have feared he would never be able to even attempt, never mind achieve.we were honest with him about his trouble, letting him know that there was nothing to be ashamed of. some people learn differently. if he was willing to work, we would help him find a way to do as much as he could in his academic career. all that was standing in his way was this math test. he had taken it three times and did better each time, but he continued to fail. he was starting to get a bit tired of me saying this was a marathon not a sprint (沖刺). my heart broke each time we would get the failing results.“mom, thanks. i love you. thanks for believing i could do this.”for one of the few times in my life, i really had nothing left to say. for that one brief moment i knew, really, really, knew that everything we did to help our son achieve what he wanted was worth it.【語篇解讀】本文是一篇夾敘夾議文。作者的兒子tom患有朗讀困難癥，所以學(xué)習(xí)不好，而紐約的高中要求學(xué)生通過五門考試才能畢業(yè)。作為母親，作者想盡一切辦法使tom相信他自己可以做到。經(jīng)過努力tom終于通過了考試。5what does the underlined word “pound” in paragraph 1 probably mean?asink suddenly. bbeat wildly.cache violently. dbreak totally.解析：選b詞義猜測題。根據(jù)第一段中的“mom, i got a 71 on the test. i did it.”并結(jié)合下文內(nèi)容可推斷，作者的兒子有朗讀困難癥，數(shù)學(xué)考了三次都沒及格，這次他考了71分，通過了考試，故作者應(yīng)該會(huì)感到非常激動(dòng)，心怦怦直跳。故pound應(yīng)意為“(心臟)劇烈地跳動(dòng)”，即beat wildly。故答案選b。6according to the text, tom was weak in .aenglish bsciencechistory dmath解析：選d細(xì)節(jié)理解題。根據(jù)第三段中的“all that was standing in his way was this math test. he had taken it three times and did better each time, but he continued to fail.”可知，tom不擅長數(shù)學(xué)，考了三次都沒有及格。故答案選d。7how did the writer feel when she wrote this text?ashe felt proud and satisfied.bshe felt surprised and bitter.cshe felt grateful and relaxed.dshe felt worried and anxious.解析：選a推理判斷題。根據(jù)最后一段最后一句“for that one brief moment i knew, really, really, knew that everything we did to help our son achieve what he wanted was worth it.”可推斷，作者對兒子最后通過考試很滿意，也為兒子感到驕傲。故答案選a。8what can be the best title for the text?aa mothers love that made the gradeba student who struggled for a diplomacfailure is the mother of successdlife is not a sprint but a marathon解析：選a標(biāo)題歸納題?？v觀全文可知，作者的兒子tom患有朗讀困難癥，所以學(xué)習(xí)不好，而紐約的高中要求學(xué)生通過五門考試才能畢業(yè)。作為母親，作者想盡一切辦法使tom相信他自己可以做到。經(jīng)過努力tom終于考了71分通過了考試。由此可推斷，是母親的愛使tom獲得了成功。a項(xiàng)符合文章主旨，適合做標(biāo)題。故答案選a。.短文改錯(cuò)charles is my more unforgettable teacher. i am an average student in high school and wasnt interesting in studying. however, i was quite enthusiastic about performing plays. after charles knew my interest, he encouraged us. he said that i had a gift for perform and suggested that i made good use of my talent. people usual do well in the things they like, and it is really true. now im a professional actor. i succeeded because of charles encouraged me a lot. i kept touch with him through letters and phone call until he died in 2003.答案：charles
