问题     It’s easy to scare people about what’s in their food, but the danger is almost never real. And the【C1】________itself kills.
    Take the panic【C2】________genetically modified organisms, or GMOs. Ninety percent of all corn grown in America is genetically modified now. That means it grew from a seed that scientists【C3】________by playing with its genes. The new genes may make corn grow faster, or they may make it less【C4】________to bugs so farmers can use【C5】________pest-killing chemicals.
    This【C6】________some people. GMOs are "unnatural," they say. A【C7】________from the movie "Seeds of Death" warns that eating GMOs "causes multiple organ system【C8】________."
    Michael Hansen of Consumer Reports sounds al-most as【C9】________when he talks about GMOs. He says, "You can’t control【C10】________you’re inserting that genetic information; it can have different effects【C11】________on the location."
    Jon Entine of Genetic Literacy Project responds: "We’ve eaten about 7 trillion meals in the 18 years【C12】________GMOs first came on the market. There’s not one documented instance of someone getting so【C13】________as a cough."
    Given all the fear from【C14】________and activists, you might be surprised to learn that most serious scientists【C15】________with him. "There have been about 2,000 studies," says Entine, and "there is no【C16】________of human harm in a major peer-reviewed journal."
    That might be enough to reassure people if they knew how widespread and familiar GMOs really are—but【C17】________they think of GMOs as something strange and new, they think more tests are needed.
    【C18】________people don’t worry about crops bred in【C19】________varieties for centuries without farmers having any idea exactly what genetic changes【C20】________  
【C4】
选项 A、abundant
B、addicted
C、artificial
D、appetizing
答案D
解析 此处填入形容词，说明改良玉米和bugs“害虫”之间的关系，此处应该表示积极色彩，即表示“不招惹害虫”，D项appetizing“开胃的，刺激食欲的”，跟less相连，符合语义。A项abundant“丰富的”，代入空格，表示“对害虫来说，基因使玉米没那么丰富”，句意不通。B项addicted“上瘾的”，be addicted to表示“对……上瘾”，玉米不可能对害虫上瘾，因此排除B项。C项artificial“人工的”后不能接to，也排除。
