All of us eat every day, but most of us don’t understand nutrition(营养). 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(补充)for the diet than synthetic vitamins.

False. There is no difference. A vitamin has the same properties(性质)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.

1.The main purpose of the passage is to 　　　　　　 .

A. list today’s standards of some food and nutrition

B. introduce what should be eaten and what not

高二英语单项填空中等难度题查看答案及解析

Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.

Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it！”

But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮层) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代数) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.

Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.

1.According to the first paragraph，________.

A. the function of our brain is like that of the muscle

B. until now it's impossible to explain the brain's mystery

C. many people believe one's intelligence is naturally determined

D. one's brain grows stronger as the age increases

2.Training muscles is compared to ________.

A. using the brain

B. connecting things in your brain

C. lifting weights

D. doing research about the brain

3.What is Paragraph 3 mainly about_________?

The complex structure of the brain.

B. How changes in the muscles affect the brain.

C. The importance of the brain.

D. How the brain becomes stronger by learning new things.

4.What does the underlined word “perspicacious” in the last paragraph probably mean_________?

A. Strong.　　　B. Smart.　　         C. Popular.　         D. Active.

5.The paragraph that follows the passage will most probably talk about _______.

A. the differences between animals’ brains and humans’ brains

B. the relation between human brains and muscles

C. scientists’ findings about animals’ brains

D. how to make your brain smarter through self-development
