1 . Summer heat can be dangerous, and heat leads to tragedy far too often. According to Kidsandcars Organization, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.

For Bishop Curry, a fifth grader from McKinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry drew up a sketch(草图) of a device he called "Oasis."

The device would be attached to car seats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the car seat, it would begin to circulate cool air. Curry also designs the device using GPS and Wi-Fi technology, which would alarm the child's parents and, if there was no response from them, the police.

Curry's father believes that the invention has potential. "The cool thing about Bishop's thinking is none of this technology is new," he said. "We feel like the way he's thinking and combining all these technologies will get to production faster." His father even introduced the device to Toyota, where he works as an engineer.

In January, Curry's father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. They have raised more than twice that--over $46,000.

"I was so proud of him for thinking of a solution," the father said. "We always just complain about things and rarely offer solutions."

The British sense of humor differs from other countries because it is     1     (general) more negative. When it comes to making the British laugh, there is nothing more     2     (effect) than a socially inappropriate joke.

Popular British comedy shows such as Fawlty Towers, Blackadder and the Office     3     （be）full of sarcasm（讽刺）, teasing and self-deprecation（自嘲）. It reflects the culture     4     fooling and complaining is part of everyday life.

While most British people don’t take these jokes too seriously, foreigners feel     5     (puzzle) about those jokes. A recent survey found that most foreigners     6     (visit) Britain found that the British are “too proud”,       7     (friend) and have almost no sense of humor.

4 . In Chinese cities, food deliverymen are often seen riding at full speed through busy traffic. They rushed from restaurants to different destinations, even under bad weather conditions.

The article The Food Deliverymen Are Trapped in the App pointed out that on food delivery service platforms, Eleme and Meituan, the time limit and the route for each delivery order is calculated by an algorithm（算法）.But the algorithm doesn't consider real-life situations, such as red lights, speed limits and fully occupied elevators.

The time limit for a delivery order within 2 kilometers is 30 minutes, even shorter in recent years. Delay could mean a fine. So deliverymen rev up, often breaking traffic rules, putting their own lives at risk.

Many people asked the platforms to improve the regulations imposed（强加） on the deliverymen. In response to this demand, Eleme announced it would add a button to the app, which allowed customers to extend the time limits for their orders, and encouraged customers to show more respect for deliverymen. But some people felt that the company was staying away from the problem and changing people's attention. Some held the view that the company was putting the responsibility on the customers rather than solving the problem itself.

As to delivery delays, solutions are far from enough. As a matter of fact, when a delivery delay happens and the company can' t reach an agreement with the customer on the responsibility, the deliveryman is usually the final one responsible for the delay. The Shanghai Customer Council commented that it was unfair for the deliveryman to be the only side responsible for a delay and problems should be solved between the companies and their employees. Besides, market regulatory departments should stop companies from setting tight schedules for their deliverymen and keep them safe on the roads.

1. What does the underlined expression "rev up” in Paragraph 3 probably mean?

A．Run away.	B．Speed up.
C．Wander around.	D．Slow down.

2. Who actually gets the blame for a delivery delay?

B．Solve the problems of delivery delays with the customers.

C．Stop companies from setting tight schedules for their employees.

D．Employ more deliverymen for the delivery companies.

4. What's the text mainly about?

A．The customers' rights should be protected.

B．Food delivery regulations need improvement.

6 . Kaitlin Woolley and Ayelet Fishbach report in Psychological Science that a meal taken “family-style” from a central plate can greatly improve the outcome of later negotiations.

Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of competition. However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.

For the first test they included 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed corn chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began.

The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules.

The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（13.2 rounds）. A similar experiment was conducted with 104 participants and Goldfish crackers（饼干）, this time negotiating an airline's route prices. The results were much the same, with the food-sharers negotiating successfully 63. 3% of the time and those who did not share doing so 42. 9%of the time.

8 . The COVID-19 continues to be a healthy threat around the world. Governments, communities and individuals are looking for ways to teach children how to protect themselves.    1    They might want to follow the advice pf imaginative creatures that are adorable,colorful and furry!

Muppets(提线木偶)are puppets from the children’s showSesame Streetcreated by Sesame Workshop.Sesame Workshop started a campaign called Caring for Each Other.    2    The project includes messages for children and caregivers.It offers reading,math and science activities along with songs and fun,educational videos.

Elmo,Grover and other Sesame Street Muppets star in new public service advertisements(PSAs)from the Sesame Workshop.These PSAs teach children about the importance of handwashing and safe ways to sneeze,limiting the spread of germs.    3    Elmo is probably one of the most famous Muppets.

9 . In the United States，the baby boomer generation(婴儿潮一代) include those who were born in the time after World War II. Those babies have retired or are now reaching the retirement age. As these adults age, many of their adult children worry about how to take care of their aging parents. In the United States it is not common for several generations to live under one roof. Once children grow up and get married, they move out, leaving their aging parents to care for themselves. When these aging parents can no longer take care of themselves because of age or illness, it is not uncommon for adult children in the US to place their elderly parents in a nursing home.

A nursing home is a place that offers care for the elderly and ill. As the name suggests，nursing homes have professionals including nurses, doctors and social workers to help aging adults deal with the challenges of daily life. And their mental health could be guaranteed for elderly people to get relaxed, accompanied by those of the same age. Most nursing homes also have social activities for the elderly to participate in and keep active. These activities range from games to dance classes, and movie nights. Nursing homes are supposed to provide three nutritious meals for their residents.

Nursing homes are controversial, however. There have been cases across the country of staff in nursing homes treating the elderly residents badly and even robbing them. There are different states and federal agencies that are supposed to oversee(监管) nursing homes. Some people feel that it should be the responsibility of family members, especially adult children, to care for their aging or sick parents. However, many adult children have their own children and families to take care of, and do not have the means to care for their elderly parents; others worry about medical skills needed if their elderly parents are seriously ill. And these problems of caring for parents are bothering more and more adults in the US at present.

10 . It is believed that around half the US adult population will be obese (肥胖的) by 2030, while one in four will fall into the severely obese category. This is according to a new study led by the Harvard T.H. Chan School of Public Health, which found that levels of obesity are increasing in every state. Indeed the predictions show that levels of severe obesity could be higher than 25 percent in half of states.

“Especially striking was our finding that among adults with very low income (less than $20,000 per year), severe obesity is predicted to be the most common in 44 states—almost everywhere in the US,” a researcher said.

The research was carried out to inform state policymakers—and perhaps help change the tendency. The study authors say the best form of attack is prevention. Limiting intake of sugar is stressed as one of the most effective and cost-effective methods for reducing obesity levels, and a tax likely to save more money than it costs.

Sugar (and the sugar industry) has come under fire for its role in promoting obesity. Indeed, one recent study published in September 2019 puts responsibility for today’s obesity epidemic (流行病) firmly on the shoulders of sugar, concluding high-sugar diets during childhood in the seventies and eighties could be behind the rise.

“We knew from previous work that obesity is increasing in the US, and that some states and demographic groups (人群) are at higher risk, but we were surprised that even the states with the lowest obesity will be above 35 percent in 2030—a level currently considered high, a researcher told Newsweek. What is clear is that we will not be able to treat our way out of this epidemic—achieving and keeping weight loss is difficult—so prevention efforts will be key to making progress in this area.”

1. What’s the most surprising finding in the study?

A．Over 25% of people will be seriously obese.

B．Levels of obesity are increasing in every state.

C．poor adults are more likely to be severely obese.

2. What is the best way to solve the problem according to the passage?

A．To reduce the tax.	B．To limit intake of sugar.
C．To reduce obesity level.	D．To inform policymakers.

3. What does the underlined word “fire” actually refer to in paragraph 4?

A．Blame from researchers.	B．Rapid chemical change.
C．Current obesity epidemic.	D．High-sugar diets.

4. What’s the main idea of the last two paragraphs?

A．Obesity is increasing everywhere in the US.

B．All states in America are at the same level of obesity.

C．Maintaining weight loss is a good way to deal with obesity.

D．Diets with less sugar are vital to preventing the problem of obesity.
