1 . Small amounts of exercise could have a great effect on happiness.

According to a new review of research about good moods and physical activities, people who work out even once a week or for as little as 10 minutes a day tend to be more cheerful than those who never exercise. And any type of exercise may be helpful.

A number of past studies have noted that physically active people have much lower risks of developing depression and anxiety than people who rarely move.

Fewer past studies explored links between physical activity and upbeat emotions, especially in people who already were psychologically healthy, and those studies often looked at a single age group or type of exercise.

So for the new review, the Michigan researchers found, exercise was strongly linked to happiness. The type of exercise did not seem to matter. Some happy people walked or jogged. Others practiced yoga-style posing and stretching. And the amount of exercise needed to influence happiness was slight. In several studies, people who worked out only once or twice a week said they felt much happier than those who never exercised. In other studies, 10 minutes a day of physical activity was linked with happy moods.

But because most of the studies in this review were observational, it is not possible yet to establish whether exercise directly causes changes in happiness or if the two just happen to occur together often. In that case, exercise would not have helped to make people happy; rather, their happiness would have helped to make them exercisers

2 . 阅读下面的短文，根据其内容写一篇60词左右的内容概要。

Babe Didrikson Zaharias was one of the most extraordinary athletes of all time. She achieved particular success in basketball, track and field, and golf. She also competed in baseball, boxing, diving and many other sports. In 1950, the Associated Press declared Babe Zaharias to be the “Woman Athlete of the Half-Century”.

From a young age, her goal was to be “the greatest athlete to ever live”. As a teenager, she acquired the nickname “Babe” in reference to Babe Ruth, a professional baseball player. She never passed up a chance to play ball. One day, when she was a little girl, her mother sent her to the grocery store to buy some beef for dinner. On the way home, Babe spotted some boys playing baseball. She dropped her purchases and joined the game. An hour later, her angry mother showed up, looking for the groceries. Babe pointed to where she’d left it. A dog was happily enjoying the last piece.

Zaharias gained fame at the 1932 Olympic Games. She won gold medals in the javelin (标枪) throw and the 80-metre hurdles (跨栏), but she was deprived of a third gold medal in the high jump because she had used the unorthodox (不正规的) Western roll to achieve the highest jump. Her Olympic success brought her national attention.

In 1932, Zaharias began playing golf and was soon winning important championships in the sport. In 1950, Zaharias helped found the Ladies Professional Golf Association, and she became the LPGA’s star competitor. Not only did she attract interest in the women’s game, she revolutionized the sport and was known for her powerful drives.

Zaharias died of cancer in 1956, at the age of 45.

3 . Now several cities and states are considering passing laws when it comes to people who walk while texting (发短信). A law passed in Honolulu allows police officers to fine pedestrians(行人) between $15 and $99 for staring at their phones while crossing the street.

“Unluckily, we’re a major city with more pedestrians on the crosswalks, particularly our old people, than almost any other city in the country,” said Honolulu mayor Kirk Caldwell at a meeting. “So, passing a law is necessary and timely.”

The town of Montclair, California, took it one step further and passed a law making it illegal to talk, text or use earbuds (耳塞) on the phone when crossing the street. For the first time, people will be given a warning, and after that, the fine is $ 100. What’s more, farther north in Ontario, under the “Phones Down, Heads Up Act”, pedestrians can be fined if caught crossing the road while holding and using the phones. Fines start at $ 50.

This movement to pass such laws has a reason: Pedestrian deaths are on the rise. According to the National Safety Council, there were 5,987 pedestrian deaths—the highest number since 1990. This problem isn’t new, nor is it limited to deaths. There are a rising number of injuries from texting while crossing a street.

According to research, texing resulted in a higher rate of incidents than failure to look right or left when crossing. By comparison, talking on the phone led to only a slight increase of accidents and listening to music had no influence on safety. The results were published in the journal Injury Prevention.

So, in the opinion of David Canepa, a member of the Board of Supervisors in San Mateo Country, California, the government should tell people where to look when they’re walking down the street. He said, “At the end of the day, people will understand the value of public safety. Making the laws will save lives.”

1. What is Kirk Caldwell trying to talk about in the second paragraph?

A．The increasing traffic accidents.	B．People’s dependence on phones.
C．The reason for passing the law.	D．Old people’s bad situation.

2. What do we know about pedestrians using phones on crosswalks?

A．All of them will receive a warning first.

B．They’re fined at most 50 dollars in Ontario.

C．They’re fined at most 99 dollars in Honolulu.

D．They’re fined more than 100 dollars in California.

3. Which of the following is most dangerous according to research?

A．Texting while crossing roads.	B．Making calls when crossing roads.
C．Enjoying music when crossing roads.	D．Crossing roads without looking left or right.

4. What can we infer about David Ganepa’s opinion on the laws?

A．They are hard to understand.	B．They are helpful for people.
C．They are against people’s wishes.	D．They are well received by pedestrians.

4 . Recently, there is a view on the Internet that “the rise of pig price will lead to the rise of other food prices, thus leading to a substantial rise in overall prices”. It should be said that this judgment is not scientific. We should objectively understand the position of pork price in the overall price and its possible linkage effect.

At present, the main problem faced by the pork price is the lack of pork production capacity, which has nothing to do with inflation and will not lead to inflation. The rise of pork price only affects the upstream and downstream of pig industry and other related products such as meat, but has limited impact on the overall price. At present, China's agricultural product supply is sufficient; the production capacity of consumer goods is constantly improving; the service supply is more diversified, and the monetary policy remains stable, which provides a solid foundation for the stable operation of prices.

Keeping prices, especially the prices of important people's livelihood commodities, basically stable is related to the basic life of the people. In the face of rising pork prices, the state's policy of ensuring supply and stabilizing prices continues to increase. From choosing the right opportunity to put frozen meat reserve to starting the price subsidy mechanism, from rectifying the improper restriction and prohibition measures to protecting the land for pig farms, from special financial support to financial insurance escort, all departments are taking measures. With the gradual effectiveness of the measures, the price of pork will be stable in the future. It is worth noting that the data of the Ministry of Commerce on September 10th shows that the increase of pork wholesale price has fallen back from the previous week (from September 2nd to 8th).

1. From the first paragraph of the article, what’s the correct point of view we can get?

A．The rise of pig price will lead to the rise of other food prices, which will lead to the sharp rise of overall prices.

B．The rise of pig price will lead to the decrease of other food prices, which will lead to the sharp decline of overall price.

C．People should objectively understand the position of pork price in the overall price and its possible linkage effect.

D．It is not important to understand the position of pork price in the overall price and the linkage effect it can produce.

2. According to the second paragraph, we can know why the price of pork is rising?

A．The reason for the rise of pork price is related to inflation.

B．The reason for the rise of pork price is related to the death of pigs.

C．The reason for the rise of pork price is related to market demand.

D．The reason for the rise of pork price is related to the lack of pork production capacity.

3. According to the third paragraph of the article, what will be the price of pork in the future?

A．The price of pork will keep rising.	B．The price of pork will probably be stable.
C．The price of pork will not be stable.	D．The price of pork will never be stable.

4. The most suitable title for this article is _______.

A．The Price of Pork Is Rising.

B．What will People Do in the Face of Rising Pork Prices?

C．The Impact of Rising Pork Prices.

D．The Impact of Rising Pork Prices on People.

7 . The US Ambassador to the UK officially launched a ship named Mayflower on Wednesday, 400 years to the day after a wooden ship with that name sailed from an English port and changed the history of two continents.

Unlike the merchant ship that carried a group of European settlers to a new life across the Atlantic Ocean in 1620, the new Mayflower named by U S Ambassador Robert Wood Johnson has no crew or passengers. It will cross the sea powered by sun and wind, and controlled by artificial intelligence (AI).

Johnson said the high-tech ship, developed jointly by British-based research organization ProMare and US tech giant IBM, showed that “the pioneering spirit of the Mayflower really lives on”. “We’re heading out with the same spirit of adventure and determination and hope for the future as the original colonists (殖民者),” said Johnson.

Like the Mayflower in 1620, the new ship will travel from Plymouth, England, to Plymouth, Massachusetts. The ship’s launch in Plymouth is one of several Mayflower commemorations. They involve British, Americans and Dutch institutions — many of the 17th-century colonists had left England for Holland before the voyage — and the Wampanoag people, who had lived for thousands of years in what is now New England. In 1620, the Wampanoag helped the exhausted Mayflower settlers survive their first winter. But soon colonial expansion and new diseases were having a big impact on North America’s Native Indians. Wampanoag stories have been marginalized (使边缘化) on past Mayflower anniversaries (周年纪念), but they are playing a big part in events and exhibitions this time around. “The story of the Mayflower is one that really can’t be told without telling also the story of the Wampanoag,” said Paula Peters, a Wampanoag writer.

The Mayflower Autonomous Ship is intended to explore parts of oceans too difficult or dangerous for people to reach. Andy Stanford-Clark, Chief Technology Officer for IBM in the UK and Ireland, said the ship’s launch “is a very exciting stage of the journey toward crewless shipping” that could pave the way for AI-driven commercial ships and research ships.

The 50-foot ship will go through six months of sea trials and make short trips before setting out on its trans-Atlantic trip to measure ocean health: assessing the impact of climate change, measuring micro-plastic pollution and studying populations of whales and dolphins.

1. What do we know about the new Mayflower?

A．It is a wooden ship.

B．It is powered by clean energy.

C．It will carry a large load of goods.

D．It will carry a small number of passengers.

2. What does the new Mayflower represent according to Johnson?

A．The sufferings of the British people in history.

B．The friendship between the US and the UK.

C．The long-lasting bravery of humankind.

D．The development of high technology.

3. What change can the launch of the new Mayflower bring?

A．It will seek help for Native Americans.

B．It will bring Wampanoag stories to light.

C．It will encourage more and more sea exploration.

D．It will help describe the colonists’ journey in detail.

4. What is the practical use of the new Mayflower?

A．It can protect commercial ships.

B．It can carry out certain surveys.

C．It can save animals stuck in water.

D．It can get rid of underwater dangers.

8 . Unlike early space travelers, today’s astronauts enjoy various freeze-dried meals, snacks, and desserts that can be commonly found on Earth. However, delicious as the food is, it pales in comparison with a freshly-cooked meal. Now astronauts at the International Space Station (ISS) may soon be able to have freshly-baked cookies to eat, thanks to a newly-acquired space oven.

The oven built by NanoRacks—a space company that helps develop experiments for the ISS—was sent to the ISS on November 2,2019. It’s specially designed to withstand the space station’s microgravity environment. Mary Murphy, a NanoRacks manager who helped develop the space oven, says the biggest challenge was keeping the cookie dough from floating inside the oven.

To solve the hurdle, the inventors decided to keep the cookie dough inside a sealed tray that can be placed directly into the oven. Once the cookies are baked, the plate is automatically transported to an integrated cooling vent(出口) which can only be accessed once the treats are at room temperature.

Murphy says, “What is so interesting about this is that it’ll be the first time that something will be baked in space. What will the cookies look like? While we don’t know for sure how the experiment will turn out, we’re looking forward to finding out and learning how to best bake food products in space.”

While the cookies’ appearance has been revealed, their taste will remain a mystery for some time. That’s because the freshly-baked space treats have been returned to Earth to undergo testing to ensure they’re safe to consume.

1. Why is the cookie dough kept inside a sealed tray when baked in the oven at the ISS?

A．To make it baked more easily.	B．To prevent it floating in the oven.
C．To make it convenient to take out.	D．To connect it with a cooling vent.

2. What is Mary Murphy mainly talking about in Paragraph 4?

A．Their interest in doing the experiment.	B．The expectation of the space oven.
C．The challenges they are faced with.	D．Their devotion to the research.

3. Why do the cookies need testing after they are baked?

A．To confirm their appearance.	B．To ensure that they’re delicious.
C．To make sure of their security.	D．To know if they are nutritious.

4. What may be the best title for the text?

A．A special space oven is launched into the ISS.

B．A company has developed a special space oven.

C．Freshly-cooked space food is available due to a space oven.

D．Astronauts may soon enjoy freshly-baked cookies.

9 . Canadian student Raymond Wang, 17, won the world’s largest high school science competition last Friday, taking home the top prize of $75,000 for inventing a new way to keep germs from spreading in airplane cabins (机舱).

“It is very exciting. I absolutely didn’t expect it,” Wang said by telephone from Pittsburgh, the host city for the finals of the Intel International Science and Engineering Fair (Intel ISEF). “It is really the happiest day of my life.”

Wang started thinking about the problem of disease spread on airplanes several months ago, after a steady stream of news about the Ebola outbreak in West Africa. Ebola is not spread through the air, he learned, but other infectious diseases spread through the air, the H1N1 swine flu virus and SARS virus included.

And that is a problem in airplane cabins, where everyone is breathing everyone else’s air. “When someone sneezes, there is a mess everywhere,” he explained.

Wang said he made up his mind to solve the problem when he discovered that few people in the airline industry were actively working on ways to improve the quality of airplane air.

He designed fin-shaped devices (鳍形装置) that fit into the airplane’s existing air inlets (入口). The fins redirect the airflow, creating walls of air around each passenger. Each person gets a personalized zone of fresh air, and sneezes are pushed out of the cabin before they can spread.

His invention would improve the availability of fresh air in the cabin by 190 percent, he said, and would reduce the concentration of airborne germs by 55 times. Wang believes that it would cost $1,000 per airplane and could be put in overnight. And he is already filed an application for a patent.

Wang is clearly not your average high school student. He did his project not for class but on the side, and he learned what he needed to know pretty much on his own. “This year I had to pick up fluid dynamics (流体动力学),” he said. “I kept going with it, watching some videos and looking at some papers.”

1. What is Wang’s invention for?

A．Preventing passengers from sneezing.

B．Killing germs spreading in airplane cabins.

C．Stopping some diseases from spreading on planes.

D．Controlling the spread of Ebola germs through the air

2. As for winning the award, Wang felt that      .

A．he deserved the award	B．it was out of expectation
C．it was really a challenging task	D．he should have done more for it

3. Wang decided to design fin-shaped devices        .

A．when hearing Ebola was spreading in Africa

B．when choosing to take part in the Intel ISEF

C．after deciding to have a patent of his own

D．after knowing there were few similar products

4. How do fin-shaped devices work?

A．By identifying sneezing passengers.

B．By controlling the movement of air.

C．By letting passengers be aware of germs.

D．By separating people with fin-shaped walls.

5. What information does the last paragraph pass us?

A．Opportunity is open to those well prepared for it.

B．Where there is a will, there is a way.

C．Knowledge advances by steps and not by leaps.

D．Every dog has its day.

10 . I was 13 or 14. It was summer. We lived in an old house with no screens on the window in the attic (阁楼), where my sister and I slept in the same bed. While thinking about how I might escape, I leaned sideways, and my hand landed on a floorboard that popped up (突然爆开) and almost hit me in the head. When I looked inside the open space, I could not believe my eyes: There was gold in there! I picked up a handful of gold cubes (方块) and ran to the bottom stair and yelled, “Mama — I found gold up here under the floor!” Mama simply said, “Chile, that’s insulation. Now put it all back.”

When I reached inside, my hand touched what felt like a book. I pulled it out. It was Bartlett’s Familiar Quotations. And since I was bored, I decided to see what was inside this book.

On the top left- and right-hand corners of each page was a word or phrase. I opened it to “comfort” and then “comfort and despair”, and then farther down was “comfortable”. I remembered “Doubt” “Peace” “Hope and Hopeful”. I had discovered that I was not alone in some of the things I felt and thought: What does grief feel like? What is the value and power of dreams?

In ninth grade, I got my first job, as a page at our local library. I often hid in the ladies’ room, where no one would see me, and I would read. It was at this library that I realized how some of those emotions I’d felt while reading Bartlett’s came to life in the characters I had started discovering in novels.

When I went to college, Bartlett’s came with me. Over the years, I’ve kept my original copy, and to this day I often refer to it. I have bought a few of the newer editions, but the first one is the one that helped me see more than what my young mind was able to understand.

1. Why did the author shout?

A．She hurt herself in the head.	B．She had a quarrel with her sister.
C．She found something under a floorboard.	D．She failed to get the gold out of the attic.

2. What is Paragraph 3 mainly about?

A．What the value of dreams is.	B．How different words relate to each other.
C．How the author’s life was in her childhood.	D．What the author learned from the book she found.

3. What can we learn about the author when she went to college?

A．She met Bartlett in real life.

B．She got her first job at the local library.

C．She seldom referred to the books she read before.

D．She kept Bartlett’s as one of her greatest treasures.

4. What is the author’s purpose of writing this text?

A．To introduce a famous book.	B．To show the importance of libraries.
C．To tell readers how a book changed her life.	D．To explain how she became a best-selling writer.
