问题     If you have high blood pressure, you’re in good【C1】________Hypertension affects 67 million Americans, including nearly two-thirds of people over age 60. But it isn’t an inevitable part of the aging【C2】________. It’s better to think of it as【C3】________sodium poisoning. And, there’s a way to prevent the problem—and to save many, many lives.
    A lifetime of【C4】________too much sodium (mostly in the form of table salt) raises blood pressure, and high blood pressure kills and disables people by【C5】________ strokes and heart attacks. In the United States, according to best estimates,【C6】________sodium is killing between 40,000 and 90,000 people and running up to $20 billion in medical costs a year.
    Americans on average【C7】________about 3,300 milligrams of sodium per day, but experts recommend less than 2,300 milligrams—and less than 1,500 milligrams for people over age 50, black people, or those who already have hypertension, diabetes or kidney disease, which【C8】________a majority of American adults. Either【C9】________is far below where most Americans are now.
    The reason that nearly everyone eats【C10】________too much sodium is that our food is loaded with it, and often where we don’t【C11】________or expect it. Of course ham and canned soup are full of salt, but so are many foods that are【C12】________: A blueberry cake can have more than double the salt of a serving of potato chips.【C13】________healthy-sounding food can pack【C14】________ sodium loads. Many restaurant main courses have far more sodium than is recommended for an【C15】________day.
    Doctors warn people with high blood pressure to go on a low-salt diet, but that’s virtually impossible in today’s world,【C16】________nearly 80 percent of the sodium that Americans eat comes in【C17】________and restaurant food. You can’t take it out. And【C18】________everyone, not just people with hypertension【C19】________over food labels, should be taking in less sodium. The only way to prevent millions of Americans from developing high blood pressure is for companies and restaurants to stop loading up their food with sodium. It’s not easy,【C20】________it isn’t impossible either.
【C12】
选项 A、frightening
B、surprising
C、disappointing
D、encouraging
答案B
解析 冒号后的内容为：一个蓝莓蛋糕的含盐量可能比一份薯条的含盐量的两倍还多。根据常识，蓝莓蛋糕是甜的，而薯条是咸的，前者的含盐量不应该比后者的多。而这样的说法是与人们的原本的想法相反，选B项surprising“令人惊讶的”。A项frightening表示“令人恐惧的”，强调的“害怕”之意，不符合逻辑。C项disappointing“令人失望的”，而我们一般都没想过要拿这两种食物作含盐量的比较，所以与是否感到失望无关。D项encouraging“令人鼓舞的”，无法在文中找到相关表达。
