【题目】 Healthy eating is not just what you eat, but how you eat. Here are some tips for you:

Eat with others whenever possible. Eating with other people has numerous benefits, especially for children. 1 Eating in front of the TV or computer often leads to mindless overeating.

Take time to chew your food and enjoy mealtimes. 2 We tend to rush through our meals, forgetting to enjoy the flavor and feel the taste of what is in our mouths.

Listen to your body. Ask yourself if you are really hungry, or have a glass of water to see if you are thirsty instead of hungry. 3 It actually takes a few minutes for your brain to tell your body that it has had enough food, so eat slowly.

4 A healthy breakfast can jumpstart your metabolism( 新陈代谢), and eating small, healthy meals throughout the day(rather than the standard three large meals)keeps your energy up and your metabolism going.

Avoid eating at night. 5 And then don’t eat for 12-14 hours until breakfast the next morning. Studies suggest that eating only when you’re most active and giving your digestive(消化的)system a long break each day may help to keep fit.

A. Drink plenty of water.

B. Try to have dinner earlier. C. Be careful when eating out.

D. Eat your food slowly, tasting every bite.

E. During a meal, stop eating before you feel full.

F. It allows you to follow others’ healthy eating habits.

G. Eat breakfast, and eat smaller meals throughout the day.

【题目】 The Intelligent Plant. That is the title of a recent article in The New Yorker, and new research is showing that plants have surprising abilities to sense and react to the world.

But can a plant be intelligent? Some plant scientists insist they are since they can sense, learn, remember and even react in ways that would be familiar to humans.

Michael Pollan, author of “The Botany of Desire,” says for the longest time, people who have long talked to their plants or played music for them were being considered “mad.”

The new research, he says, is in a field called plant neurobiology(神经生物学), which is not a proper name, because even scientists in the field don’t argue that plants have neurons(神经) or brains.

“They have analogous structures as humans,” Pollan explains. “Plants have all the same senses as humans. They have ways of taking all the sensory data they gather in their everyday lives, integrate it and then behave in an appropriate way in response.” In addition to hearing, taste, for example, they can sense gravity, the presence of water, or even feel that an obstacle(障碍物) is in the way of its roots, before coming into contact with it. Plant roots will change direction, he says, to avoid obstacles.

So what about pain? Do plants feel? Pollan says they do respond to anesthetics (麻醉剂). “You can put a plant out with a human anesthetic. And not only that, plants produce their own compounds that are anesthetic to us.” But scientists are unwilling to go as far as to say they are responding to pain.

How plants sense and react is still somewhat unknown. They don’t have nerve cells like humans, but they do have a system for sending electrical signals and even produce neurotransmitters (神经递质) and other chemicals the human brain uses to send signals.

1Why does the author mention the article The Intelligent Plant in the first paragraph?

A.To support his opinion.B.To introduce the topic.

C.To give an example.D.To make comparison.

2People who usually talked to their plants would be thought .

A.Intelligent.B.Crazy.C.Patient.D.Comforting.

3What does the underlined word “analogous” in paragraph 5 mean?

A.Simple.B.False.C.Flexible.D.Similar.

4What can we learn about plants according to the last two paragraphs?

A.Plants can feel and react to pain.B.Plants send two kinds of signals.

C.Plants are able to sense and react.D.Plants have their own brains.

【题目】 At a young age, Patti Wilson was told by her doctor that she was an epileptic (癫痫病患者). Her father, Jim Wilson, is a morning jogger. She ran with her father every day. After a few weeks, she told her father, “Daddy, what I’d really love to do is to break the world’s long-distance running record for women.” Her father checked the Guinness World Records and found that the farthest any woman had run was 80 miles.

As a freshman in high school, Patti announced, “I’m going to run from Orange County up to San Francisco.”(A distance of 400 miles.) “As a sophomore (二年级学生),” she went on, “I’m going to run to Portland, Oregon.”(Over 1,500-miles.) “As a junior, I’ll run to St. Louis.”(About 2,000 miles.) “As a senior, I’ll run to the White House.”(More than 3,000 miles away.)

In view of her handicap (缺陷), Patti was as ambitious as she was enthusiastic, but she said she looked at the handicap of being an epileptic as simply “an inconvenience”. She focused not on what she had lost, but on what she had left.

That year she completed her run to San Francisco wearing a T-shirt that read, “I Love Epileptics.” In her sophomore year, Patti’s classmates got behind her. They built a large poster that read — “Run, Patti, Run!”

On her second marathon (马拉松), a doctor told her she had to stop. “Doctor, you don’t understand,” she said. “I’m doing it to break the chains on the brains that limit so many others.”

She finished the run to Portland, completing her last mile with the governor of Oregon. After four months of almost continuous running from the West Coast to the East Coast, Patti arrived in Washington and shook the hand of the then President of the United States. She told him, “I wanted people to know that epileptics are normal human beings with normal lives.”

Because of Patti’s efforts, enough money had been raised to open up 19 multi-million-dollar epileptic centers around the country. If Patti Wilson can do so much with so little, what can you do to outperform (超越) yourself in a state of total wellness?

1How did Patti look at her illness?

A.She thought of it as a gift.

B.She devoted all her attention to it.

C.She faced it with discouragement.

D.She considered it a small difficulty.

2What did Patti do when a doctor asked her to stop her run?

A.She continued without quitting.

B.She focused on her treatment.

C.She followed his advice.

D.She asked for her classmates’ assistance.

3Why did the author ask the question in the last paragraph?

A.To ask readers to answer it.

B.To get inactive people to run.

C.To encourage deep thinking.

D.To show his view on success.

【题目】 The other day, I bought an expensive anti-aging cream that promised to make my face look several years younger that other women by fighting free radicals. It made me curious about what free radicals ares.Is the anti-aging cream the only way I need to protect myself?

“As a scientific term, free radicals are essentially unstable atoms, “says Arizona-based doctor, Natasha Bhuyan, M. D. “In medicine, they cause cells to break down over time and are linked to aging.”

A super simple chemistry review for you: Atoms from different elements are the building blocks that make up water, nitrogen and more. Electrons (电子) are the negatively charged atoms, and they like to be in pairs. When an electron loses its partner, it creates a free radical, which is usually unstable and highly reactive. Free radicals typically go through the body to seek out a replacement for their missing electron, and that can result in damage to cells,proteins and DNA.

So how do free radicals form and why do they happen? Bhuyan says, “Scientifically, free radicals are unpaired electrons that are seeking a mate to bond with. The theory behind free radicals is that they can lead to the imbalance between free radicals and antioxidants (抗氧化剂).” Another mini-science lesson for you: Antioxidants are natural or man made matters that can help delay or prevent some types of cell damage. They’re often found in fruits and vegetables.

A lot of the aspects of modern life — our diet, lifestyle and environmental factors like pollution, can cause oxidative stress. Over time, oxidative stress weakens cell and tissues and can leave you more easily to certain health issues including cancer. And, as beauty marketers are keenly aware,oxidative stress can also speed up the aging process. Now that your know free radicals can weak on your health, you’re probably wondering if there are any ways to prevent them from forming or at least to minimize their negative effects.

1What does the author intend to do in paragraph 1?

A.Explain the process of aging.B.State the formation of free radicals.

C.Introduce the topic of free radicals.D.Describe the harm of anti aging cream.

2Which of the following do free radicals refer to?

A.Unpaired electrons.B.Steady atoms.

C.Replacements of atoms.D.Functions of electrons.

3What can we learn about antioxidants from the text?

A.They have never been found in nature.

B.They do harm to cells, proteins and DNA.

C.They can slow down the damage of some cells.

D.They always keep balance with free radical.

4What will the author probably tell us next?

A.What exactly oxidative stress is.B.How beauty marketers promote sales.

C.Where a variety of diseases come from.D.Whether free radicals can be prevented.
