剑桥雅思5 Test 4阅读Passage 3原文翻译 the effects of light on plant and animal species 光对动植物的影响
剑桥雅思5 Test 4 Passage 3阅读答案解析第27题答案:TRUE
对应原文:第2段:the amount of experimental evidence for this phenomenon is considerable.
解析:文中提到这一现象的实验证据数量十分可观。题干中的plenty of与considerable amount of对应,evidence原词出现。即每个信息点都能在原文中找到依据,因此确定答案为TRUE
第28题答案:TRUE
对应原文: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,可以通过人工增加日照长度文章来自老烤鸭雅思在冬季引发某些种类的鸟类的繁殖行为。题干中的types, encourage, season分别与原文中的species, induce, winter替换。即每个信息点在原文中都有对应,因此确定答案为TRUE
第29题答案:NOT GIVEN
对应原文:无
解析:虽然整篇文章都在讨论光周期现象,但并没有提到任何与地理位置相关的内容。因此判断为NOT GIVEN。
第30题答案:FALSE
对应原文:第4段: For example, desert annuals germinate, flower and seed whenever suitable rainfall occurs, regardless of the day length.
解析:根据desert定位到这一句,原文意思为“只要有合适的降雨,沙漠植物就会发芽,开花,结果,而无论日照长度如何”。其中regardless of the day length与题干中的long-day plants直接冲突,因此判断为FALSE
第31题答案:FALSE
对应原文: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:根据bamboos定位到具体的句子,原文意思为“竹子会生长好多年,然后突然开花、结果、死亡”,即一生只开花一次。这与题干中的several times相冲突,因此判断为FALSE
第32题答案:TRUE
对应原文:第5段:Every bamboo of the species Chusquea abietifolia … The climatic trigger for this flowering cycle is not yet known
解析:原文中提到这一开花周期的气候出发原因还不清楚,与题干中的scientists have yet to determine对应(yet表否定),因此判断答案为TRUE
第33题答案:FALSE
对应原文: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段开头提到耐阴性植物生长速率较慢,后面又说东部铁杉幼苗是耐阴性植物,因此它应该生长的比较慢才对。这与题干中fast-growing plant相冲突,因此判断为FALSE
第34题答案:temperatures
对应原文: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:根据day length和useful cue for breeding定位到这句话。题干中的unpredicatable与原文中fluctuate对应。根据题干语法结构,空上填的应该是该动作的发出者,因此判断答案为tempretures
第35题答案:day-neutral/day-neutral plants
对应原文:第2段:Plants which flower after a period of vegetative growth, regardless of photoperiod, are known as day-neutral plants.
解析:顺着上一道题目往下,发现do not respond to light levels与regardless of photoperiod对应,由此确定句子。原文中的known as被替换成refered to,因此确定答案。
第36题答案:food/food resources/adequate food/adequate food resources
对应原文: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与increasing day lengths对应,由此定位到这一句。根据题干,空上填的应该是名词,而这一句话中只有food resources在题干上未出现,填上去之后意思也很合适。因此确定答案。
第37题答案:insects/fertilization by insects
对应原文:第4段: Long-day plants are adapted for situations that require fertilization by insects, or a long period of seed ripening.
解析:根据days are long定位到这一句,题干中的depend on与原文中require对应,由此确定答案为fertilization by insects。这道题不能单填fertilization的原因在于它无法满足空后的短语含义。
第38题答案:rainfall/suitable rainfall
对应原文:第4段:desert annuals germinate, flower and seed whenever suitable rainfall occurs, regardless of the day length.
解析:根据desert定位到这句话。题干与原文相比,变化幅度较大,用词性筛选的方法会更加简单一些。根据题干,空上填的应该是个名词,而原句中的名词只有两个:rainfall和day length。而day length填上去之后意思不合适,因此确定答案为rainfall
第39题答案:sugarcane
对应原文:第6段:others, like sugarcane, never reach a maximum, but continue to increase photosynthesis rate as light intensity rises.
解析:根据no limit to与never reach a maximum的对应定位到这一句,原文中的like被替换为such as,因此确定答案。
第40题答案:classification
对应原文: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:根据forestry and horticulutre定位到这一句,从题干语法结构可以推测出空上应该填个名词。而未在题干中出现,有语义合适的名词只剩下classification,由此确定答案。
