Next year the U.S. National Park Service will turn 100. The 100th anniversary (周年纪念日)will be celebrated across the nation.

Sally Jewell, Secretary of the Interior of the United States, started a new program called “Find Your Park.” She said being outside helps both children and adults in today’s computer-driven world.

“In this society, where we’ve got much information at out fingertips, and things to distract(分散……注意力)our brains, there is little to distract our bodies and that’s why parks and open spaces are so important and even more important with each passing year,” Jewell said.

From beautiful lands and mountains to historical and cultural places, national parks can be found in all 50 states across the U.S. The parks had nearly 293 million visits in 2014. The Golden Gate Park in San Francisco was the most popular with 15 million visits. There are 28 different kinds of national park, and each park has an important story to tell.

Jewell has invited some famous Americans to help the anniversary. American First Lady Michelle Obama and former First Lady Laura Bush were invited to share their national park stories, because the White House is one of the country’s national parks.

Mrs. Obama encouraged “people across the country to ‘Find Your Park,’ whether it’s in your backyard, or your hometown, or in one of our beautiful national parks.”

Some well-known Americans have filmed their own personal national park stories and they can be seen on National Park Foundation website. Bill Nye, known as “The Science Guy,” and actress Bella Thorne are two of the people who have shared their personal national park stories.

The program wants the public to share park experiences and memories at FindYourPark.com. The website helps people find a park near their home, not just national parks, but local parks as well.

“It’s really all about getting people outside and moving as well as getting them to recognize(认识)what parks and public lands have to offer,” Jewell said.

A recent study has shown that eating a small amount of dark chocolate every day could be good for your health. Scientists have found that a regular 2 ounces can help lower blood pressure and reduce the risk of having a heart attack or stroke(中风)without any weight gain. But take care before you reach for a large bar. The effects are canceled out if more than 30 calories are taken into your body each day, the researchers warn.

It’s already known that a chemical called polyphenol(多酚), found in chocolate, can help reduce blood pressure, and blood pressure lowered in this way can reduce the risk of death from a stroke by 8 percent and from a heart attack by 5 percent, scientists declare. And it can also reduce the risk or death in general by 4 percent.

A daily diet with a little chocolate has the same effect with some special diets designed to lower blood pressure, according to one researcher. “Although all the degree of the blood pressure reduction is small, the effects are quite obvious,” the researchers said.

However, Sara Stanner, a nutritionist at the British Heart Foundation, is quite cautious. “This study suggests that small quantities of small chocolate might have good effects on blood pressure. However, it is important to remember that chocolate is also high in fat and calories. So eating much is not good for your heart.” “Polyphenols are also found in fruits and vegetables, which can be taken in without the risks associated with overintake,” she added.

But the German study shows that the fat content does not cancel out the good effects—at least where small amounts are concerned.

2.What health benefits does dark chocolate have?

A. Eating chocolate has no health benefits.

B. Dark chocolate is not so nutritious as expected.

C. The findings of scientist’s study are not scientific.

D. Eating fruits and vegetables may be a better choice.

4.What will be discussed in the following passage?

A. Some details of the German study.

B. Benefits of fruits and vegetables.
