【#雅思考試(IELTS)# #2017年7月29日雅思閱讀考試機(jī)經(jīng)預(yù)測(cè)及解析#】2017年7月29日雅思考題是考生們十分關(guān)注的，®無憂考網(wǎng)為大家整理了2017年7月29日雅思閱讀考試機(jī)經(jīng)預(yù)測(cè)及解析，希望對(duì)參加2017年8月份以后考試的考生有特別幫助。
一、 考試概述：
本次考試的文章中又見兩篇原題，所以關(guān)注考情還是有必要的，不過最重要的還是提高自己的基本功，以不變應(yīng)萬變。從題型上面分析，填空題及判斷題依然是考查重點(diǎn)，題型涉及的還是比較全面的，不過本次考試沒有考查list of headings這種題型。據(jù)考生反應(yīng)，本次填空題出現(xiàn)了跳段現(xiàn)象，做起來比較消耗時(shí)間，所以，大家考試中還是要靈活一點(diǎn)。
二、具體題目分析

題目：Going Bananas
題型：填空題3+人名理論配對(duì)7+判斷題3
新舊程度：舊題
文章大意：香蕉的起源、發(fā)展與現(xiàn)狀
參考文章：
Going Bananas
A. The world’s favourite fruit could disappear forever in 10 years’ time. The banana is among the world’s oldest crops. Agricultural scientists believe that the first edible banana was discovered around ten thousand years ago. It has been at an evolutionary standstill ever since it was first propagated in the jungles of South-East Asia at the end of the last ice age. Normally the wild banana, a giant jungle herb called Musa acuminate, contains a mass of hard seeds that make the fruit virtually inedible. But now and then, hunter-gatherers must have discovered rare mutant plants that produced seed-less, edible fruits. Geneticists now know that the vast majority of these soft-fruited plants resulted from genetic accidents that gave their cells three copies of each chromosome instead of the usual two. This imbalance prevents seeds and pollen from developing normally, rendering the mutant plants sterile. And that is why some scientists believe the world’s most popular fruit could be doomed. It lacks the genetic diversity to fight off pests and diseases that are invading the banana plantations of Central America and the small-holdings of Africa and Asia alike.
