2018全國英語等級考試二級閱讀試題（16）

　　All of us eat every day, but most of us don’t understand nutrition(營養(yǎng)). How much do you know about good nutrition? Are the following statements true or false?

　　1. People who don’t eat meat can stay healthy.

　　True. As long as people eat enough milk, eggs and meat alternates(替代物), they can get enough protein.

　　2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.

　　False. The difference depends more on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water can lose a large quantity of vitamins.

　　3. Food eaten between meals can be just as good for health as food eaten at regular meals.

　　True. Nutritional value depends on what types of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.

　　4. Taking extra vitamins beyond the recommended daily allowances won’t give you more energy.

　　True. It’s widely believed that extra vitamins provide more energy. But taking more than the baby needs doesn’t make it function better, just as overfilling your gas tank doesn’t make your car run better.

　　5. Natural vitamins are better supplements(補(bǔ)充)for the diet than synthetic vitamins.

　　False. There is no difference. A vitamin has the same properties(性質(zhì))and specific chemical structure whether made in a laboratory or taken from plant or animal parts.

　　6. Older people need the same amount of vitamins as younger people.

　　True. Older people need the same quantity of vitamins as younger people although they need fewer calories. Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.

　　7. Food grown in poor soil is lower in vitamins than food grown in rich sold.

　　False. The vitamins in our foods are made by the plants themselves. They don’t come from the soil.

　　However, the minerals in a plant depend on the minerals in the soil.

　　If you have answered these questions correctly, you can say you know much about food and nutrition by today’s standards. But remember that nutrition is a growing science and that may be aged as new information is obtained.

　　小題1:主旨大意題。根據(jù)文章大意：我們每天都吃飯，但絕大多數(shù)人并不懂營養(yǎng)學(xué)。本文列舉了今天一些食物和營養(yǎng)的標(biāo)準(zhǔn)。故A正確。
