Question

Today, the biggest killers stem as much from our lifestyles as from bacteria and viruses.  One of the worst of these is heart disease, and specifically high blood pressure. It’s a slow, but efficient killer that robs many people of what should be the last 10, 20 or 30 years of their lives.

Scientists are claiming that they have now separated unusual ingredients in a rare seaweed discovered by fishermen off the coast of Korea that offer incredible health benefits—including the ability to restore blood pressure to normal levels.

Dr. Haengwoo Lee, a famous biochemist conducted a clinical study on these two ingredients. The first is Seanol, an extremely rare seaweed extract(浓缩物) from Ecklonia Cava that's proven to be 100 times more powerful than any land-based antioxidant(抗氧化剂). That's because it stays working in your body for 12 hours, compared to land-based antioxidants that work for 30 minutes.  "Its secret is its make-up of special chemicals that are a huge 40% fat soluble( 可溶的)," Dr. Lee explains. "Unlike nearly all land-based antioxidants that are water soluble, Seanol's protective compounds can get into things like the fatty tissues of your brain and penetrate（渗透） all three layers of your cells, including the outside, the oil-based cell membranes（细胞膜）, and your DNA."　Indeed, Seanol is so powerful, it's the only FDA-approved Ecklonia Cava marine-algae (海藻)  extract in existence.

The second ingredient is Calamarine, a deep-sea omega-3 discovery that delivers 85% more DHA omega-3s to your heart, brain, joints, and eyes. It's known to reduce the problems from tiredness and poor memory, joint pain, mood swings and depression.

With that research in mind, Dr. Lee combined Seanol and Calamarine with a high dose of vitamin D to form  Marine-D3, the newest supplement in the fight against age-related illnesses and high blood pressure.

Dr. Lee found that Calamarine delivers some of the greatest concentration of omega-3s known to science. Combined with Seanol's ability to reduce body inflammation(炎症), as well as help cells get the nutrients they need to thrive, stay healthy and protected, Marine-D3 is able to boost a body's entire well being.

The makers of Marine-D3 are so confident that you'll see fast dramatic results from this product, that if you aren't happy after two full months, simply return the unused portion and they'll buy it back. They'll even give you ten dollars extra just for giving it an honest try! That kind of faith, combined with Dr. Lee's exhaustive research, shows that Marine-D3 really is a one-of-a-kind product.

【解析】

试题分析：本文介绍了科学家从一种罕见的海藻中提取到了两种对高血压和减少疲劳和记忆力问题的成分。这两种成分制成的药品对对抗老年性疾病和高血压有很好的疗效。

1.推理题：根据文章第一段“It’s a slow, but efficient killer that robs many people of what should be the last 10, 20 or 30 years of their lives”它是缓慢却很有效的杀手，夺去了许多人本可以在持续10年、20年或30年的生命。此处的“它”指的是高血压，由此可知高血压会缩短我们的寿命。故选C。

2.推理题：阅读第二段可知科学家已经发现一种可以使血压恢复到正常水平的有效成分。故选B。

3.细节题：根据第三段最后一句“Indeed, Seanol is so powerful, it's the only FDA-approved Ecklonia Cava marine-algae (海藻)  extract in existence.”事实上，Seanol有如此强大的功效，它是唯一一个由FDA批准从Ecklonia静脉海藻中提纯的物质，由此可知是符合标准的，故A项正确；根据第三段中“a huge 40% fat soluble”40%脂溶性，可知B项错误；根据第三段中“an extremely rare seaweed extract(浓缩物) from Ecklonia Cava”一种很罕见的Ecklonia静脉海藻萃取液,可知C项错误；根据第三段中“Seanol's protective compounds can get into things like the fatty tissues of your brain”Seanol保护化合物可以进入大脑的脂肪组织，而并不是“all things”所有物质，故D错误。故选A。

4.推理题：阅读第四段可知第二种成分Calamarine可减少疲劳和记忆力的问题,缓解关节疼痛、情绪波动和抑郁症。由此可知它可以缓解疼痛，使人轻松。故选D。

5.推理题：pessimistic悲观的；indifferent中立的；doubtful怀疑的；Optimistic乐观的。阅读最后两段内容可知这两种物质制成的药品效果很好，还有促销手段，市场前景良好，可见作者对此持有乐观情绪。故选D。
