Question

【題目】 You'd better eat a banana while you still can. British scientists say that the fruit may disappear by 2050.

One ______ is climate change. Scientists from the UK collected data(數(shù)據(jù)) from 27 countries and regions that produced 86 percent of the world's bananas. They found that climate change has improved growing conditions in 21 of these countries and regions. _______ ,if temperatures keep rising, this advantage will disappear. The perfect temperatures range for growing bananas is between 24℃and 32℃. If temperatures get too high, they will _____ growing.

Diseases are another danger to bananas. Unlike other crops, the bananas come from shoot cuttings rather than seeds. It means that all bananas plants have the _______ genotype(基因型). If a disease is able to kill one plant, it could kill them all.

One serious disease is called Panama Disease. Caused by a fungus(真菌) in the soil, it can easily ______ If one banana plantation suffers from the disease, it will take 30 years before it can grow bananas again. Scientists have yet to find a cure to fight Panama Disease.

Answer 1

【答案】

【1】A

【2】C

【3】C

【4】A

【5】B

【解析】

本文主要分析了在2050年前香蕉會(huì)消失的原因，如：氣候的改變和疾病。

【1】句意：一個(gè)原因是氣候變化。

reason理由；example例子；advantage優(yōu)勢(shì)，根據(jù)上文British scientists say that the fruit may disappear by 2050. 英國(guó)科學(xué)家說(shuō)，這種水果可能在2050年消失。可知本句在解釋將要消失的原因，故選A。

【2】句意：然而，如果溫度持續(xù)上升，這一優(yōu)勢(shì)就會(huì)消失。

Besides除了；Suddenly突然；However然而，根據(jù)上文They found that climate change has improved growing conditions in 21 of these countries and regions. 他們發(fā)現(xiàn)，氣候變化改善了其中21個(gè)國(guó)家和地區(qū)的生長(zhǎng)條件。與下文if temperatures keep rising, this advantage will disappear. 如果溫度持續(xù)上升，這一優(yōu)勢(shì)就會(huì)消失�？芍�上下文屬于轉(zhuǎn)折關(guān)系，故選C。

【3】句意：如果溫度太高，它們就會(huì)停止生長(zhǎng)。

start開(kāi)始；keep保持；stop停止，根據(jù)上文The perfect temperatures range for growing bananas is between 24℃and 32℃.可知種植香蕉的最佳溫度范圍在24℃至32℃之間，If temperatures get too high如果溫度太高，可推斷出它們就會(huì)停止生長(zhǎng)。故選C。

【4】句意：這意味著所有香蕉植物都有相同的基因型。

same一樣；strong強(qiáng)壯；simple簡(jiǎn)單，Unlike other crops, the bananas come from shoot cuttings rather than seeds. 與其他作物不同的是，香蕉來(lái)自扦插而不是種子�？芍�所有香蕉植物都有相同的基因型，故選A。

【5】句意：由土壤中的真菌引起的疾病，如果一個(gè)香蕉種植園患有這種疾病，它很容易傳播。

disappear消失；spread傳播；change改變，根據(jù)句意，可知這種真菌引起的疾病很容易傳播，故選B。
