American students had been learning at home for more than a year during the pandemic (流行病). When they returned to in-person learning, teachers began to see more behavioral problems.

Sarah Potpinka is an art teacher at Putnam High School in Connecticut. She said she saw more fights and arguments among students online and in person. Some refused to wear the required face coverings. Other students broke school rules by leaving in the middle of class to meet up with friends. Obviously throughout this pandemic, the students spent a lot of time at home and because of that they lack in those social skills.

Bad behavior among students is part of what experts are calling a mental health crisis among children. Even before the pandemic, research found that bad behavior in the classroom was increasing.

A group of mental health organizations say in a recent Hopeful Futures Campaign report that one in three students reported feeling lonely or hopeless. Half of all mental illnesses are present by the age of 14 but few students get the services they need. The report, released last month, also warns that suicide is the second leading cause of death among those aged 14 to 18 in 2019.

Richard Douglas is a school psychologist at Putnam High School with over 30 years of experience.Douglas said that during the pandemic there have been many things that disrupt (破坏) families. More time at home could lead to more arguments with family members. Douglas feels school officials provide enough support to deal with the mental health crisis at Putnam. For the school of around just 250students, there is also a counselor, a social worker, and two recently hired interventionists (干预者). Interventionists help identify learning and behavioral problems among students.

Despite behavioral problems among students after returning to in-person classes, Potpinka said the change has been better for the students. She said it is easier to keep students engaged in schoolwork face to face. It is also easier to seek help for them when there is trouble.

Americans with small families own a small car or a large one. If both parents are working, they usually have two cars. When the family is large, one of the cars is sold and they will buy a van (住房汽车).

A small car can hold (容纳) four persons and a large car can hold six persons but it is very crowded(拥挤). A van hold seven persons easily, so a family of three children could ask their grandparents to go on a holiday travel. They could all travel together.

Mr. Hagen and his wife had a third child last year. This made them sell a second car and buy a van. Their sixth and seventh seats are used to put other things, for a family of five must carry many suitcases (衣箱) when they travel. When they arrive at their grandparents’ home, the suitcases that are brought into the two seats can then carry the grandparents.

Americans call vans motor homes. A motor home is always used for holidays. When a family are traveling to the mountains or to the seaside, they can live in their motor home for a few days or weeks. All the members of a big family can enjoy a happier life when they are traveling together. That is why motor homes have become very popular. In America there are many parks for motor homes.

The health problems about cloned animals , particularly those who appear healthy but have hidden illnesses or problems that appear unexpectedly later in life, have the potential to cause real risks to the safety of the food products from those animals. Ian Wilmut, a lead scientist involved in the creation of Dolly, the first cloned animal, has warned that even small imbalances in a clone’s hormone, protein, or fat levels could bring its milk or meat into danger.

As part of its risk assessment on animal cloning, the Food and Drug Administration (FDA) concluded that milk and meat from cloned animals and their offspring (后代)are as safe to eat as products from conventional animals. The FDA further announced that it would not require food products from cloned animals or their offspring to be labeled as such.

Consumer watchdog groups pointed out that the FDA’s analysis was based on limited data supplied mainly from the cloning companies themselves. In addition, while food safety is an obvious concern of consumers, it is not the only issue that makes people uncomfortable with animal cloning. For example, surveys indicate that 63 percent of consumers would not buy food from cloned animals even if it were labeled as “safe”. Concerns about the morality of cloning, as well as concerns for animal welfare, lead a big majority of people to oppose cloning animals for food. However, these issues were not considered by the FDA. Without labels to identify cloned foods, consumers who oppose animal cloning would be forced to make purchases against their principles without knowing. Consumers have a right to know how their food is produced so they can make informed decisions about what they buy and what they feed their families.
