In the United States, the word "holiday" is synonymous with celebration. The following ten holidays per year are proclaimed by the federal government.

Independence Day

Independence Day is annually celebrated on July 4 and is often known as "the Fourth of July”. It is the anniversary of the publication of the declaration of independence from Great Britain in 1776. Now it is celebrated in all the states. The army marks the occasion by firing a 13-gun salute every year. Ceremonies may include parades, official speeches, visits to historic monuments and fireworks displays.

Memorial Day

This holiday, on the fourth Monday of every May, is a day on which Americans honor the dead. Originally a day on which flags and flowers were placed on graves of soldiers who died in the American Civil War, now it has become a day on which the dead of all wars and all other dead are remembered the same way.

Veterans Day

Veterans Day was established to honor Americans who had served in World War I. It falls on November 11, the day when that war ended in 1918, but it now honors veterans of all wars in which the United States has fought Veterans' organizations hold parades or other special ceremonies, and the US president customarily places a wreath on the Tomb of the Unknowns at Arlington National.

Thanksgiving

Thanksgiving Day is celebrated on the fourth Thursday in November. It has been an annual tradition in the United States since 1863. Today, people celebrate Thanksgiving to remember these early days. The most important part of the celebration is a traditional dinner.

Guangzhou outbreak linked to strains in India

The gene sequencing of the COVID-19 outbreak in Guangzhou. Guangdong province, indicates it is very similar in structure to the mutated strains detected in India, a senior health official from the city said on Sunday.

“And it has the characteristic of quick spread.” Chen Bin, deputy director of the city's health commission, said at a news conference in Guangzhou on Sunday.

She urged relevant departments and medical staff to act quickly to block the chain of infection and control the spread of the coronavirus in the southern metropolis.

Zhang Zhoubin, deputy director of the Guangzhou center for disease control and prevention, said the strain of coronavirus spreads easily.

The city reported five confirmed eases and 21 asymptomatic carriers as of 2 pm Sunday after the first con finned case was detected in the city's Liwan district on May 21, Chen said.

To prevent the virus from spreading, the city government tightened its disease control and prevention measures over the weekend. Six communities and housing estates previously designated as low-risk areas were raised to medium-risk ones, Chen said.

In addition to asking local residents to get vaccinated, the city has organized nucleic acid testing in Haizhu and Yuexiu districts starting from Sunday. Residents in specific areas of Tianhe, Baiyun and Panyu districts have also been required to take nucleic acid tests to expand the screening of suspected patients and asymptomatic carriers.

Liwan previously required all its residents to take nucleic acid tests.

As of Saturday, more than 2-25 million residents of the city have had samples collected for nucleic acid tests, Chen said. More than 10,000 medical workers from the entire city have been sent to Liwan to help vaccinate locals against COVID-19 and collect samples for nucleic acid testing.

Preventing heart disease is a topic I think about all the time, given my family history of heart disease. So last summer, I travelled to Bolivia. The natives, called the Tsimane, were reported to have the healthiest hearts in the world. I wanted to learn what they could teach me about preventing heart disease.

Getting to the Tsimane wasn't easy. They lived in small family groups of about 60 people along river banks. We finally found one of the villages at sunset. That night, we set up our tents in the middle of the village. Thatched huts surrounded us, with no electricity or modern conveniences.

At first, I thought they mainly got their calorics from meat. However, I found food such as rice and com made up nearly 70% of their diet. The food was not processed, lacking added sugars or salts.

During my stay there, I went hunting and fishing with the men and played soccer with the kids. I found the Tsimane were standing or walking nearly all of their waking hours. Men spent lots of time tracking animals. Fanning and gathering, mostly done by children and women, were all-day affairs.

I also got a clear idea of how they rested. As soon as the sun went down, people returned to their huts and went to sleep. And with the call of the cock in the morning, another day began.

The lifespan of the Tsimane is actually much shorter than those living in the US. Various factors, like animal attacks and infections, bring down the lifespan. But up until the day they die, they are often very healthy. While heart disease kills thousands of Americans every year and costs nearly a billion dollars a day, the Tsimane remind us that wealth doesn't necessarily buy health.

8. Why does the author pay so much attention to preventing heart disease?

A．He dreams of becoming a doctor.	B．He wants to teach others about the topic.
C．His family members encourage him to do so.	D．He was born with a high risk of heart disease.

9. Which factors did the author mainly focus on in his research?

A．Housing, food and cooperation.	B．Diet, activity and rest.
C．Physical work, social life and lifespan.	D．Group size, family history and consumption

10. What was the Tsimane 's sleep-wake cycle mainly based on?

A．Natural sound.

B．Routine activity.

C．Animal behaviour.

D．Natural light.

11. What might the author advise us to do after his travels in Bolivia?

A．Take in less sugar and salt.	B．Stand less and walk more.
C．Eat white meat instead of red meat.	D．Live in the middle of the community.

In some areas of California, it’s so dry that farmers aren’t willing to plant crops this season. Growers, north of San Francisco, have begun pulling out of local farmers markets.

County Line Harvest, which farms more than 30 acres in Petaluma, hasn’t had enough water to grow all the peppers, lettuces and other produce for a long time, according to a video on its Instagram page. Nearby farms are saying the same, emphasizing (强调) the effect of the extended dry periods.

California grows a third of the United States' vegetables and two-thirds of the nation's fruits and nuts. If dry weather prevents farmers from growing plants, that could lead to pushing up the price of food that's already starting to affect the U.S. economy.

“Due to severe drought, for the first time in 21 years, we will not be able to grow this summer in Petaluma ," County Line said in its post.

Drew Lerner, president of World Weather Inc. in Kansas, said California “missed the rainy season" and won't see much moisture (水分) over the next several months.

A La Nina weather pattern in the Pacific pushed winter storms north and away from the state, leaving it with less moisture than usual. As California gets most of its water from winter storms, little relief is expected before October.

That has left growers such as Shao Shan Fann in a bind. The business can’t offer the selection of Asian vegetables and Bay Area staples it usually grows at its Bolinas location, according to its website.

Nearby, Green Valley Community Farm has access to only about 5% of the water it usually relies on, owner David Plescia said. He’s looking for new land with enough water to use, and also has a permit in the works to grow cannabis to make up for the lost income. If it doesn’t make it, he’ll leave the fields empty.

“It’s part of our generation’s cross to bear, figuring out how to run small — or medium-scale farm businesses in this kind of atmosphere of highly variable rainfall,” Andrew said.

12. What does the underlined word “extended” in the second paragraph mean?

A．Hot.

B．Short.

C．Long.

D．Wonderful.

13. Which is the result if the dry weather stops famers from planting crops?

A．The increase in the price of food.	B．The growth of economy in U.S.
C．Less moisture than usual.	D．The low price of Asian vegetables.

14. From what Andrew said, we can infer (推断) all of the following statements EXCEPT that________.

A．The climate is not very good

B．It is part of the burden for people of his generation

C．It is hard for him to run his farm businesses in such bad climate

D．He is sure that the serious drought will come to an end soon

15. What does the passage mainly talk about?

A．How do the famers run businesses in California.

B．How does the owner look for new land with enough water

C．California farmers facing drought choose not to plant crops.

D．The farm economy of the United States has changed a lot.

It can be hard to include exercise in our busy lives.    16    Here are some common misunderstandings about exercise and what researeh actually tells us.

I exercise once a week, and that's enough.

    17    Therefore, you need to exercise every day. Mix it up and keep it interesting as maintaining high levels of physical activity throughout your life is associated with the best health outcomes.

    18    

The good news is（bat recent guidelines have removed the need for physical activity to be at least 30 minutes at a time. There is no minimum time（最少少时间）to exercise, so carry out active daily chores, such as carrying heavy shopping bags and doing garden work, to improve your health. Try to do exercise “snacks”, such as climbing a few flights of stairs at a high enough intensity to make you a bit out of breath.

I'm too old to exercise.

This is not true. Evidence shows that aging alone is not a cause of major problems until you are in your mid-90s.    19    

I'm not feeling well, so 1 shouldn't exercise.

If you have a fever, are really unwell or are experiencing high levels of pain or exhaustion, don't exercise.    20    But you should listen to your body and decrease your exercise load if you need to.

A．I am fit, so I don't need to exercise.

B．In most other cases, being physically active is safe.

C．There are a lot of reasons why people don’t exercise.

D．Physical activity decreases the risk of excessive weight gain.

E．I need to spend at least 30 minutes exercising at a time.

F．The health benefits of exercise won't last if you only exercise once a week.

G．Strength, power and muscle mass can be increased, even at this advanced age.

A little boy almost thought of himself as the unluckiest child in the world because poliomyelitis （小儿麻痹症）made him unable to walk like normal people. He seldom played with his classmates, and when the teacher asked him to answer questions, he always lowered his head without a word.

One spring, the boy's father asked for some young trees from the neighbor. He wanted to plant them in the front of the house. He told his children to plant a tree each person. The father said to the children, "Whose tree grows best, I will buy him or her a favorite gift" The boy also wanted to get his father's gift. But seeing his brothers and sisters carrying water to water the trees happily, he had a terrible idea: he hoped the tree he planted would die soon. So he never attended to it.

A few days later, when the little boy went to see his tree again, he was surprised to find it not only didn't die, but also grew some fresh leaves, and compared with the trees of his brother and sister, his appeared greener and more vital. His father kept his promise, bought the little boy his favorite gift and said to him, "from the tree you planted, you will become a great person when you grow up."
