听力原文： When people have enough B vitamins, their appetite is good and their nerves are calm. B vitamins in the diet come from some meats and vegetables, milk, cottage cheese, and whole grains.

When a grain is processed, it loses vitamins. For example, there is a big difference between white and brown rice. When rice is processed, the brown outside is lost. The brown outside of rice has an important B vitamin which white rice lacks. In short, brown rice has more B vitamins than processed rice.

Vitamin C keeps the cells of the body together. It helps skin tissue recover from cuts and bums. Vitamin C in the diet comes from tomatoes, fruits like lemons and oranges, and some vegetables such as cabbage and green peppers.

Vitamin D is called the "sunshine" vitamin. When people sit outside, ultraviolet rays from the sun change fat in their skin to vita- min D. Vitamin D disease in children are called rickets. Rickets is more common in countries that have long winters with little sun- shine.

听力原文： The growing interest of consumers in the safety and more nutritional quality of

the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, such claims make it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form. the basis for folklore. Almost daily the public is besieged for "no-aging" diets, new vitamins, and other wonderful foods. There are numerous unconfirmed reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than treated grains and the like.

I have always believed that prevention is better than cure. I now know why I love Kellogg's Honey Nut Cornflakes. They contain vitamins, including B12! If foods contain added vitamins, as

听力原文：The earth's oceans are colossal, so much bigger than the land area that they cove

听力原文： The earth's oceans are colossal, so much bigger than the land area that they cover 70% of the surface of the earth. They give us food and materials and a major constituent in the formation of our weather. The extremes of temperature on the earth would be much greater, and many places would be too hot or too cold for humans without the oceans to act as the earth's thermostat.

As our supply of fresh water becomes more and more scarce, we have naturally looked to the oceans, the greatest source of water on earth. But there is so much salt in sea water that it is not fit for human consumption. Scientists have been trying to find ways to turn this salt water into fresh water. Machines for the conversion of water are already at work in certain parts of the world, but their cost is still exorbitant. Science will have to find much cheaper ways to do the job.

Possibilities for food abound in the ocean. In addition to the hundreds of varieties of fish, some kinds of seaweed can be eaten. It is nutritious enough, containing many proteins, vitamins, and minerals that humans need for survival, but so far no one has been able to figure out how to disguise its awful taste.

(30)

A．70% of the land surface.

B．Food.

C．Drinking water directly.

D．Mineral water.

听力原文：As a personal fitness trainer, I have to tell you that one of the worst things yo

u can do when you're working out at the gym is drink soda. Aside from making you feel bloated, the sugars in the soda keep your body from absorbing water, which can make your muscles cramp up. I mean, I don't even recommend those so-called juice "drinks" that contain a bunch of added sweeteners. Stick to the natural stuff: one hundred percent juice is great—it contains fructose, which helps you rebuild your muscles, and vitamins and... like that. If you want, you can make your own sports drink by diluting some juice and adding a little salt— I add about a teaspoon for every quart of diluted juice. This helps keep you hydrated, and helps you replenish the salts you sweat out.

What does the speaker say to avoid before exercise？

A．Drinking soda

B．Eating sweet foods

C．Eating a large meal

D．Overstretching muscles
