劍橋雅思最新真題題源詳解

前言

　　雅思學(xué)術(shù)類閱讀考試采用的是題庫(kù)制，在實(shí)戰(zhàn)考試中，3篇閱讀文章都考新文章的概率極低，通常新老文章的比例是2新+1老、1新+2老或3老。而且，根據(jù)筆者十幾年來(lái)教授雅思學(xué)術(shù)類閱讀及數(shù)十次親身參加實(shí)戰(zhàn)考試的經(jīng)驗(yàn)，越是重復(fù)考過(guò)的老文章越容易再次出現(xiàn)。因此，本書(shū)收錄了近2年重復(fù)率較高的真題源文，比如：美國(guó)肥胖、龍涎香、海獺、考拉、人類五種感覺(jué)、厄爾尼諾現(xiàn)象、計(jì)時(shí)器發(fā)展史、閱讀的教學(xué)方法、機(jī)器人和海底熱流排放等多篇文章。　　近2年共計(jì)有3671名參加環(huán)球雅思學(xué)校培訓(xùn)的考生在課堂上對(duì)由以上文章匯編成的10套題進(jìn)行了真題源文演練，效果喜人：2007年有162名學(xué)員取得了8分以上的成績(jī)并領(lǐng)取了獎(jiǎng)學(xué)金。我相信，“強(qiáng)者恒強(qiáng)”，這些真題源文在2009年也一定會(huì)再次出現(xiàn)，讓演練過(guò)這些真題的考生真正受益。　　對(duì)于已經(jīng)接受過(guò)雅思學(xué)術(shù)類閱讀考試正規(guī)培訓(xùn)的考生，他們可以直接演練這些由真題源文匯編成的10套高仿真模擬題。對(duì)于沒(méi)有接受過(guò)雅思學(xué)術(shù)類閱讀考試正規(guī)培訓(xùn)和雖接受過(guò)培訓(xùn)但依然對(duì)考試摸不著頭腦的考生，建議先閱讀雅思學(xué)術(shù)類閱讀考試題型和評(píng)分標(biāo)準(zhǔn)，以便快速掌握學(xué)術(shù)類閱讀的特點(diǎn)、解題的正確思路和技巧，并精心揣摩套題精解示范，然后再做練習(xí)。

章節(jié)摘錄

　　C Classical biological control is the introduction of natural enemies to a new locale where they did not originate or do not occur naturally. This is usually done by government authorities. In many instances the complex of natural enemies associated with an insect pest may be inadequate. This is especially evident when an insect pest is accidentally introduced into a new geographic area without its associated natural enemies. These introduced pests are referred to as exotic pests and comprise about 40％ of the insect pests in the United States. Examples of introduced vegetable pests include the European corn borer, one of the most destructive insects in North America. To obtain the needed natural enemies, scientists turned to classical biological control. This is the practice of importing, and releasing for establishment, natural enemies to control an introduced （exotic） pest, although it is also practiced against native insect pests. The first step in the process is to determine the origin of the introduced pest and then collect appropriate natural enemies associated with the pest or closely related species. The natural enemy is then passed through a rigorous quarantine process, to ensure that no unwanted organisms （such as by per parasitoids） are introduced, then they are mass produced, and released. Follow-up studies are conducted to determine if the natural enemy becomes successfully established at the site of release, and to assess the long-term benefit of its presence.　　D There are many examples of successful classical biological control programs. One of the earliest successes was with the cottony cushion scale, a pest that was devastating the California citrus industry in the late 1800s. A predatory insect, the Vidalia beetle, and a parasitoid fly were introduced from Australia. Within a few years the cottony cushion scale was completely controlled by these introduced natural enemies.　　E Damage from the Alfalfa weevil, a serious introduced pest of forage, was substantially reduced by the introduction of several natural enemies. About 20 years after their introduction, the population of weevils, in the alfalfa area treated for alfalfa weevil in the northeastern United States, was reduced by 75 percent.
