(原创)1.C New studies showed that because of climate(气候)change, some food such as honey, coffee, peanuts and fruit are becoming“endangered”. Why? Let's take a closer look.
Honey Bees live on pollen(花粉). But rising $CO_2$ makes the pollen have less protein(蛋白质)in it. Pollen is becoming junk food for bees! Bees aren't getting enough nutrition(营养). They may die out. Warmer temperatures also make plants flower earlier. It's so early that bees may still be little babies. They are not old enough to pollinate(授粉)them.2.E
Coffee South America, Africa, Asia and Hawaii are home to coffee.3.AThis makes it easier for viruses(病毒) and bugs to grow. They may hurt the coffee plants. The result? Big cuts in coffee beans and less coffee in your cup. Scientists said that if Earth keeps warming up, half of the coffee production areas(种植区)won't be there by the year 2050.
Peanuts Peanut plants grow best when they get five months of warm weather and 50—100 centimetres of rain each year.4.G In 2011, the drought(干旱)across the peanut-growing southeastern USA led many plants to die.
Fruit If you love peaches and cherries, you may feel sad about this: the fruit will drop in amount and quality. Fruit trees, including cherries, plums, pears and peaches, need “chilling hours”.5.F If they skip(跳过)the cold days, the fruit trees have a hard time flowering in spring. By the year 2030, scientists said there will be much fewer days colder than 7℃.

答案： 1. C 根据下文“New studies showed that because of climate change，some food such as honey，coffee，peanuts and fruit are becoming ‘endangered’.”可知，新的研究表明，由于气候变化，蜂蜜、咖啡、花生和水果等食物正在濒临“灭绝”。说明气候变化对食物的负面影响。C项“气候变化可能正‘吃掉’你最喜欢的食物！”符合语境，故选 C。

2. E 根据上文“They are not old enough to pollinate them.”可知，蜜蜂们还不够大，不能给花授粉，应该会导致不好的结果。E项“The fewer bees there are to pollinate，the less honey they make.”表示授粉的蜜蜂越少，酿的蜜就越少，很好地描述了蜜蜂太小不能授粉导致的结果，故选 E。

3. A 根据上文“South America，Africa，Asia and Hawaii are home to coffee.”和下文“This makes it easier for viruses and bugs to grow. They may hurt the coffee plants.”可知，上文讲了南美洲、非洲、亚洲和夏威夷是咖啡的故乡，下文讲了气候变化造成的负面影响，前后形成强烈的对比，A项“但是这些地方的气温正在上升。”起到转折作用，符合语境，故选 A。

4. G 根据下文“In 2011，the drought across the peanut-growing southeastern USA led many plants to die.”可知，下文举了一个干旱造成许多植物死亡的例子，说明设空处跟干旱有关，G项“如果将有更多恶劣天气，比如干旱，这可不是好消息。”符合语境，故选 G。
＞＞ 解释关系
5. F 根据上文“Fruit trees，including cherries，plums，pears and peaches，need ‘chilling hours’.”可知，此处引出了一个用双引号引起来的词“chilling hours”，因此下文需要有对该词的解释。F项“它是每年冬天它们处于 7℃以下温度的一段时间。”很好地解释了什么是 chilling hours，符合语境，故选 F。
