【題目】根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

Palm oil(棕櫚油) is the most widely used vegetable oil worldwide．It’s found in a wide variety of products from of vitamins to chocolate and bread．【1】 The former makes it easy to spread，while the latter makes it good for our body．

With half of the world’s palm oil coming from Indonesia，orangutans(猩猩) have suffered a lot．【3】 What’s worse，in 2015，wildfires endangered one-third of the remaining orangutans．Palm oil farms have also threatened tigers and elephants and caused water and air pollution．

【4】 However，it’s not easy given that no other natural vegetable oil has both of its qualities．Now，scientists are creating a new oil to replace it by using food waste and M．pulcherrima，a yeast(酵母) that grows on leaves，fruits and flowers．【5】 Besides, the yeast can be widely produced in any weather．The scientists say their biggest challenge was to find a cheap way to change the sugars in the food waste to a form that the yeast can take in easily．The team is now trying to test if they can produce the oil at a lower cost．

A．Palm trees need lots of land to grow．

B．The easiest solution is to stop using palm oil so widely．

C．The palm oil is so expensive that many families can’t afford it．

D．In the last 20 years，over 80% of their habitat has been destroyed．

E．There are many things we can do to protect the endangered wild animals．

【解析】文章講述棕櫚油的廣泛使用所帶來的環(huán)境問題以及科學(xué)家對(duì)此的解決辦法。

【1】考查對(duì)上下文語境的理解�？涨熬湟猓核�在各種各樣的產(chǎn)品中被發(fā)現(xiàn)，從維生素到巧克力和面包。空后句意：前者使它容易擴(kuò)散，而后者則對(duì)我們的身體有益。故F（這種油很受歡迎，因?yàn)樗�有高的熔點(diǎn)并含有健康的脂肪。）承接上下文，The oil is popular呼應(yīng)上一句，a high melting point對(duì)應(yīng)easy to spread，healthy fats對(duì)應(yīng)good for our body，故選F。

【2】考查對(duì)上下文語境的理解。空前句意：但是棕櫚油的流行代價(jià)高昂�？蘸缶湟猓航Y(jié)果，印度尼西亞數(shù)千英畝的熱帶雨林為了給它們騰出空間正在被破壞。故這里A（棕櫚樹需要很多的生長地。）符合上下文，故選A。
