Recently, the American Heart Association surveyed 1,000 people nationwide about their thoughts on sodium and heart health. 61% said that they believed sea salt Was a low-sodium alternative to table salt. They can be forgiven for thinking so. Sea salt is marketed as a healthy food, added to soups, potato chips and a wide variety of packaged snacks labeled "low sodium", "all natural" and "healthy". But in reality, sea salt and table salt are not terribly different, at least chemically. The real differences are in how the two are used in cooking.
Table salt comes from underground salt deposits. Companies that sell it typically add something to keep it from clumping (结块).

[单项选择]Passage Two
Questions 57 to G1 are based on the following passage.
For most people, fat is a burden. It doesn’t really matter where it appears, we just don’t want it. But it turns out that our bodies also make a unique form of fat tissue that behaves remarkably unlike any other: rather than storing excess energy, this fat actually burns through it. It’s called brown fat and health experts confirm for the first time that healthy adults have stores of this tissue, which researchers hope to study further as a potential new weight-loss treatment.
Human newborns have been known to have any significant deposits of brown fat, so called because of its abnormally high concentration of dark---colored mitochondria (线粒体), the engines that sustain cell activity. The primary purpose of brown fat is to regulate body temperature: the mitochondria-packed cells are designed to burn high quantities of sugar, and release that energy as heat a mechanism that newborns rely on
A. Because people are getting older and older.
B. Because we have a new kind of fat-white fat.
C. Because we don’t need it to regulate our temperature any more.
D. Because human beings only have it in the front and back of the neck.

[填空题]Questions 51 to 55 are based on the following passage.
Canadian authorities relayed that suspicion to the U. S. Coast Guard, which dispatched a cutter to intercept the vessel. After a two-week chase, the cutter’s crew finally boarded the Cao Yu 6025, a stateless ship, south of Japan. In the hold, they found damning evidence: 110 tons of tuna and shark fins, and a drift gillnet almost 20 kilometers long--an indiscriminate killer of marine life banned on high seas under an international agreement.
Out of sight, and mostly out of mind, the oceans are under siege. Scientists from around the world are reporting global disturbances in the seas that threaten to bring Richard Cashin’s grim warning home to every Canadian household. From the polar seas to the tropics, fish populations have collapsed or teeter on the brink. In a third of the Pacific, plankton that form the foundation of the marine food chain are vanishing.
