Question

Americans have developed an olive oil habit. Out to dinner recently, I saw a man dipping his white bread in olive oil and then pouring it all over his salad, saying, "Wow, this is so good for me!"

But is olive oil the healthiest fat? No, it's not. You might ask, doesn't it lower cholesterol(胆固醇)? Well, only when you substitute olive oil in equivalent amounts for butter or oils that are higher in saturated（饱和的）fat. Olive oil doesn't lower cholesterol; it just doesn't raise it as much.

You may be better off with canola（菜籽油） oil. The 1999 Lyon Diet Heart Study found that a Mediterranean diet significantly reduced heart attacks and premature deaths. Many people attributed this to eating a lot of olive oil. But it was increased consumption of canola oil that accounted for these improvements.

Also, study participants ate more whole-grain bread, vegetables, fish and fruit, and less meat. Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does.

Another study found that olive oil reduced blood flow by 31%. Canola oil and fish oil don't. (You want to increase blood flow to all body parts.)

I like the taste of olive oil, and I use it sometimes. It's a healthier fat than many others, but it's not nearly as healthy as canola oil -- or fish oil and flaxseed oil, for that matter, which also have lots of omega-3s. And a tablespoon of any oil has 126 calories. Think about that before you pour it on.

【解析】

试题分析：美国人养成食用橄榄油的习惯，并认为橄榄油是最健康的油，但真相并非如此。实际上，橄榄油还不如菜籽油健康。

1.B推理判断题。根据文章第一段Americans have developed an olive oil habit可知美国人已经养成了一种食用橄榄油的习惯，而且他们认为这种油是很健康的。根据下文的描述But is olive oil the healthiest fat也可以推测出这一点。故选B。

2.A 推理判断题。根据文章第三段You may be better off with canola oil和最后一段It's a healthier fat than many others, but it's not nearly as healthy as canola oil可知作者认为菜籽油更加健康，所以可能会建议人们吃菜籽油而不是橄榄油。故选A。

3.A 推理判断题。根据第二段But is olive oil the healthiest fat? No, it's not；第四段Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does以及最后一段It's a healthier fat than many others, but it's not nearly as healthy as canola oil可知在作者看来，橄榄油并没有人们想象的那么健康。故选A。

4.C 细节题。根据第三段But it was increased consumption of canola oil that accounted for these improvements可知这种现象的真正原因是人们食用了更多的菜籽油。故选C。
