问题     You are going to read a list of subheadings and a text. Choose the most suitable subheading from the list [A] to [G] for each numbered paragraph (41-45). There are two extra subheadings which you do not need to use. Mark your answers on the ANSWER SHEET. (10 points)
    [A] Coconuts are using plastic
    [B] More plastic is used nowadays
    [C] I thought the problems were solved
    [D] A breakthrough about beating plastic
    [E] There will be more plastic in the ocean than fish by weight
    [F] Plastic is invading our food chain and more
    [G] Things were getting worse
    For the past decade or so, I’ve been at war with coconuts. Not all coconuts, you understand, just those that are shrink-wrapped in plastic. I started taking on retailers in my native Britain on this issue around 2005.
    【R1】__________
    After tears and excuses (theirs not mine) that included the fact that unwrapped coconuts constituted a health and safety nightmare—small children might, they claimed, inhale the fibrous hair of the natural shell—there were concessions. I moved on, confident that this would be sorted.
    【R2】__________
    How wrong I was. I returned, almost full time, to the plastic pandemic in January 2018. Things were much worse, even the coconuts. In my local stores, they are now not only shrink-wrapped but come on their own plastic stand, with a plastic ring pull and are marketed as "genuine coconuts". Oh, my God.
    【R3】__________
    But, of course, the plastic pandemic moves far beyond coconuts or any other stubbornly wrapped consumable. We’re becoming familiar with the eye-popping statistics. A garbage truck worth of plastic empties into the ocean every minute. Worldwide, humankind produces over 300 million tons of plastic each year, and this is increasing. Researchers believe as many as 51 trillion fragments of plastic— known as microplastic (characterized as pieces under 5mm)—are polluting waterways and marine environments.
    【R4】__________
    The contours of catastrophe, of course, are never easy to define, and there is much we still don’t understand. Plastic has been detected throughout our own food chain, now invading honey, beer and table salt. Studies show that microplastics can act as vectors transporting some of the most persistent toxic chemicals ever produced, and long ago banned on land. But we can say this: If we do nothing to slow down our consumption of plastic by 2050, there will be more plastic in the ocean than fish by weight.
    【R5】__________
    Let’s be clear. Nobody feels good about this and everybody wants change. But how? Scientific researchers recently announced a breakthrough, accidentally accelerating the way enzymes in bacteria
    found on a Japanese trash heap could eat through plastic. The media responded in its typically restrained way, suggesting the plastic pandemic is all but beaten. This is not the case. It will be many years before enzymes can be deployed on plastic, if at all.
【R5】
选项
答案D
解析 本段主要讲了关于降解塑料的最新突破，也提出了作者的看法：技术很美好，但是离我们很遥远。因此应该选择[D]。
