劍橋雅思5test4passage3答案及解析
第27題答案是:TRUE
對(duì)應(yīng)原文:第2段:the amount of experimental evidence for this phenomenon is considerable.
解析:文中提到這一現(xiàn)象的實(shí)驗(yàn)證據(jù)數(shù)量十分可觀。題干中的plenty of與considerable amount of對(duì)應(yīng),evidence原詞出現(xiàn)。即每個(gè)信息點(diǎn)都能在原文中找到依據(jù),因此確定答案為T(mén)RUE
第28題答案是:TRUE
對(duì)應(yīng)原文:第2段:some species of birds’breeding can be induced even in midwinter simply by increasing day length artificially
解析:文中提到,可以通過(guò)人工增加日照長(zhǎng)度在冬季引發(fā)某些種類(lèi)的鳥(niǎo)類(lèi)的繁殖行為。題干中的types,encourage,season分別與原文中的species,induce,winter替換。即每個(gè)信息點(diǎn)在原文中都有對(duì)應(yīng),因此確定答案為T(mén)RUE
第29題答案是:NOT GIVEN
對(duì)應(yīng)原文:無(wú)
解析:雖然整篇文章都在討論光周期現(xiàn)象,但并沒(méi)有提到任何與地理位置相關(guān)的內(nèi)容。因此判斷為NOT GIVEN。
第30題答案是:FALSE
對(duì)應(yīng)原文:第4段:For example,desert annuals germinate,flower and seed whenever suitable rainfall occurs,regardless of the day length.
解析:根據(jù)desert定位到這一句,原文意思為“只要有合適的降雨,沙漠植物就會(huì)發(fā)芽,開(kāi)花,結(jié)果,而無(wú)論日照長(zhǎng)度如何”。其中regardless of the day length與題干中的long-day plants直接沖突,因此判斷為FALSE
第31題答案是:FALSE
對(duì)應(yīng)原文:第5段:Bamboos are perennial grasses that remain in a vegetative state for many years and then suddenly flower,fruit and die
解析:根據(jù)bamboos定位到具體的句子,原文意思為“竹子會(huì)生長(zhǎng)好多年,然后突然開(kāi)花、結(jié)果、死亡”,即一生只開(kāi)花一次。這與題干中的several times相沖突,因此判斷為FALSE
第32題答案是:TRUE
對(duì)應(yīng)原文:第5段:Every bamboo of the species Chusquea abietifolia…The climatic trigger for this flowering cycle is not yet known
解析:原文中提到這一開(kāi)花周期的氣候出發(fā)原因還不清楚,與題干中的scientists have yet to determine對(duì)應(yīng)(yet表否定),因此判斷答案為T(mén)RUE
第33題答案是:FALSE
對(duì)應(yīng)原文:第7段:Shade-tolerant plants have lower photosynthetic rates and hence have lower growth rates…eastern hemlock seedlings are shade-tolerant.
解析:第7段開(kāi)頭提到耐陰性植物生長(zhǎng)速率較慢,后面又說(shuō)東部鐵杉幼苗是耐陰性植物,因此它應(yīng)該生長(zhǎng)的比較慢才對(duì)。這與題干中fast-growing plant相沖突,因此判斷為FALSE
第34題答案是:temperatures
對(duì)應(yīng)原文:第2段:Day length is an excellent cue,because it provides a perfectly predictable pattern of change within the year.In the temperate zone in spring,temperatures fluctuate greatly from day to day
解析:根據(jù)day length和useful cue for breeding定位到這句話(huà)。題干中的unpredicatable與原文中fluctuate對(duì)應(yīng)。根據(jù)題干語(yǔ)法結(jié)構(gòu),空上填的應(yīng)該是該動(dòng)作的發(fā)出者,因此判斷答案為tempretures
第35題答案是:day-neutral/day-neutral plants
對(duì)應(yīng)原文:第2段:Plants which flower after a period of vegetative growth,regardless of photoperiod,are known as day-neutral plants.
解析:順著上一道題目往下,發(fā)現(xiàn)do not respond to light levels與regardless of photoperiod對(duì)應(yīng),由此確定句子。原文中的known as被替換成refered to,因此確定答案。
第36題答案是:food/food resources/adequate food/adequate food resources
對(duì)應(yīng)原文:第3段:Thus many temperate-zone birds use the increasing day lengths in spring as a cue to begin the nesting cycle,because this is a point when adequate food resources will be assured.
解析:longer days與increasing day lengths對(duì)應(yīng),由此定位到這一句。根據(jù)題干,空上填的應(yīng)該是名詞,而這一句話(huà)中只有food resources在題干上未出現(xiàn),填上去之后意思也很合適。因此確定答案。
第37題答案是:insects/fertilization by insects
對(duì)應(yīng)原文:第4段:Long-day plants are adapted for situations that require fertilization by insects,or a long period of seed ripening.
解析:根據(jù)days are long定位到這一句,題干中的depend on與原文中require對(duì)應(yīng),由此確定答案為fertilization by insects。這道題不能單填fertilization的原因在于它無(wú)法滿(mǎn)足空后的短語(yǔ)含義。
第38題答案是:rainfall/suitable rainfall
對(duì)應(yīng)原文:第4段:desert annuals germinate,flower and seed whenever suitable rainfall occurs,regardless of the day length.
解析:根據(jù)desert定位到這句話(huà)。題干與原文相比,變化幅度較大,用詞性篩選的方法會(huì)更加簡(jiǎn)單一些。根據(jù)題干,空上填的應(yīng)該是個(gè)名詞,而原句中的名詞只有兩個(gè):rainfall和day length。而day length填上去之后意思不合適,因此確定答案為rainfall
第39題答案是:sugarcane
對(duì)應(yīng)原文:第6段:others,like sugarcane,never reach a maximum,but continue to increase photosynthesis rate as light intensity rises.
解析:根據(jù)no limit to與never reach a maximum的對(duì)應(yīng)定位到這一句,原文中的like被替換為such as,因此確定答案。
第40題答案是:classification
對(duì)應(yīng)原文:第7段:Plants in general can be divided into two groups:shade-tolerant species and shade-intolerant species.This classification is commonly used in forestry and horticulture.
解析:根據(jù)forestry and horticulutre定位到這一句,從題干語(yǔ)法結(jié)構(gòu)可以推測(cè)出空上應(yīng)該填個(gè)名詞。而未在題干中出現(xiàn),有語(yǔ)義合適的名詞只剩下classification,由此確定答案。
