雅思閱讀和托福閱讀哪個(gè)難
雅思和托福考試中，都有聽(tīng)說(shuō)讀寫(xiě)的考試科目。那么對(duì)于閱讀部分而言，到底是雅思閱讀難，還是托福閱讀難呢?具體的兩部分的考察有什么區(qū)別呢?到底哪部分的難度更大呢?下面小編為大家整理了詳細(xì)的內(nèi)容，供大家參考!
雅思閱讀和托福閱讀哪個(gè)難?
雅思閱讀詞匯量要求6000，主要有8種題型：matching、multiple choice、list of headings、T/F/NG、summary、sentence completion、short answer、table。這8種題型我是按照由難至簡(jiǎn)的順序排列的，matching不僅對(duì)詞匯量要求是最高的，關(guān)鍵需要很強(qiáng)的語(yǔ)言理解能力和定位能力，而最簡(jiǎn)單的table題屬于送分題，只要抓住定位詞和考點(diǎn)詞的同義替換，答案很明顯。雅思閱讀的文章長(zhǎng)度平均每篇是900字以上，最多可至1500字左右，但是雅思閱讀考查的核心并非讓學(xué)生去閱讀全文，沒(méi)有那個(gè)時(shí)間，也沒(méi)有必要，所有題目的本質(zhì)就是同義替換，再加上一些基本的做題技巧，教授雅思閱讀高分學(xué)員比托福閱讀高分學(xué)員容易。
托福閱讀詞匯量要求8000，題型官方指南上是給出了十種：細(xì)節(jié)題、詞匯題、指代題、反面信息題、句子插入題、句子簡(jiǎn)化題、推理題、修飾目的題、文章內(nèi)容小結(jié)題和表格分類(lèi)題。通過(guò)研究TPO真題1-19套，可以發(fā)現(xiàn)，托福閱讀還包括作者觀點(diǎn)題和段落結(jié)構(gòu)題。從題型上看托福閱讀比雅思閱讀多出4種，但是托福閱讀全部都是選擇題，這一點(diǎn)中國(guó)學(xué)生更能適應(yīng)，只要掌握最基本的一些做題技巧加上考點(diǎn)詞匯的記憶，抓住文章主旨，按照8大考點(diǎn)(轉(zhuǎn)折、比較、因果、對(duì)比、例證、列舉、定義、特殊符號(hào))分析句子邏輯，結(jié)合原文定位，排除干擾選項(xiàng)，不難得出答案。但是在實(shí)際的教學(xué)中，尤其是2010年，托福閱讀比雅思閱讀難出高分(25分以上)，原因在于兩點(diǎn)：1)詞匯量，尤其是考點(diǎn)詞匯的同義替換。托福詞匯考點(diǎn)有三種，一種是你認(rèn)識(shí)的單詞，選項(xiàng)也正好有跟該單詞接近含義的選項(xiàng)，這種是最簡(jiǎn)單的;第二種是你不認(rèn)識(shí)的單詞，但是可以回原文根據(jù)5種猜詞技巧猜該單詞的大致含義，排除錯(cuò)誤選項(xiàng)得出答案;第三種是你認(rèn)識(shí)的單詞，但是選項(xiàng)中沒(méi)有接近含義的選項(xiàng)，實(shí)際上考察的是“熟悉的陌生人”，如project做動(dòng)詞表示預(yù)測(cè)，推斷。例：TPO3 passage2 Depletion of the Ogallala Aquifer
It is projected that the remaining Ogallala water will,by the year 2030,support only 35 to 40 percent of the irrigated acreage in Texas that is supported in 1980.
這種詞匯題學(xué)生的錯(cuò)誤率會(huì)比較高，不過(guò)多做幾遍，掌握規(guī)律了也不會(huì)特別難。2)粗心，托福閱讀考察的主要是細(xì)節(jié)，一個(gè)轉(zhuǎn)折詞，一個(gè)否定，都可以改變答案的方向，在我的教學(xué)中，發(fā)現(xiàn)很多學(xué)生非常不善于抓住這些做題的細(xì)節(jié)，導(dǎo)致一些不該丟掉分丟掉了。
綜上，如果詞匯量不大不夠善于抓細(xì)節(jié)的學(xué)生可以選擇雅思，反之，選擇托福會(huì)比較合適。
托福閱讀TPO32第1篇:Plant Colonization
【1】Colonization is one way in which plants can change the ecology of a site. Colonization is a process with two components: invasion and survival. The rate at which a site is colonized by plants depends on both the rate at which individual organisms (seeds, spores, immature or mature individuals) arrive at the site and their success at becoming established and surviving. Success in colonization depends to a great extent on there being a site available for colonization—a safe site where disturbance by fire or by cutting down of trees has either removed competing species or reduced levels of competition and other negative interactions to a level at which the invading species can become established. For a given rate of invasion, colonization of a moist, fertile site is likely to be much more rapid than that of a dry, infertile site because of poor survival on the latter. A fertile, plowed field is rapidly invaded by a large variety of weeds, whereas a neighboring construction site from which the soil has beencompacted or removed to expose a coarse, infertile parent material may remain virtually free of vegetation for many months or even years despite receiving the same input of seeds as the plowed field.
【2】Both the rate of invasion and the rate of extinction vary greatly among different plant species. Pioneer species—those that occur only in the earliest stages of colonization—tend to have high rates of invasion because they produce very large numbers of reproductive propagules (seeds, spores, and so on) and because they have an efficient means of dispersal (normally, wind).
【3】If colonizers produce short-lived reproductive propagules, then they must produce very large numbers unless they have an efficient means of dispersal to suitable new habitats. Many plants depend on wind for dispersal and produce abundant quantities of small, relatively short-lived seeds to compensate for the fact that wind is not always a reliable means of reaching the appropriate type of habitat. Alternative strategies have evolved in some plants, such as those that produce fewer but larger seeds that are dispersed to suitable sites by birds or small mammals or those that produce long-lived seeds. Many forest plants seem to exhibit the latter adaptation, and viable seeds of pioneer species can be found in large numbers on some forest floors. For example, as many as 1,125 viable seeds per square meter were found in a 100-year-old Douglas fir/western hemlock forest in coastal British Columbia. Nearly all the seeds that had germinated from this seed bank were from pioneer species. The rapid colonization ofsuch sites after disturbance is undoubtedly in part a reflection of the large seed bank on the forest floor.
【4】An adaptation that is well developed in colonizing species is a high degree of variation in germination (the beginning of a seed's growth). Seeds of a given species exhibit a wide range of germination dates, increasing the probability that at least some of the seeds will germinate during a period of favorable environmental conditions. This is particularly important for species that colonize an environment where there is no existing vegetation to ameliorate climatic extremes and in which there may be great climatic diversity.
【5】Species succession in plant communities, i.e., the temporal sequence of appearance and disappearance of species is dependent on events occurring at different stages in the life history of a species. Variation in rates of invasion and growth plays an important role in determining patterns of succession, especially secondary succession. The species that are first to colonize a site are those that produce abundant seed that is distributed successfully to new sites. Such species generally grow rapidly and quickly dominate new sites, excluding other species with lower invasion and growth rates. The first community that occupies a disturbed area therefore may be composed of species with the highest rate of invasion, whereas the community of the subsequent stage may consist of plants with similar survival rates but lower invasion rates.
