Parents of children and teens who play football may worry about their bodies getting injury. Younger football players have the lowest chance of injury. 1. Therefore, it’s necessary for players to know the rules of playing football whether they are young or old. The following can be used to reduce the chance of injuries while players are still enjoying the game.
2. The American Academy of Pediatrics advises players and their families talk about whether the risks of injury outweighs the benefits of playing football. Football has many benefits, including regular exercise, learning to be part of a team,and social growth and development. Families who decide to play can take steps to reduce the chances of serious injury.
Play by the rules. When players know the rules of the game—what’s legal and what’s not—fewer injuries happen. 3. For example, players should know that in football they can’t come from behind, crash into a player’s legs, and steal the ball. It’s legal and safer to go after the ball rather than the player.
Wear legal equipment. 4. Because illegal equipment leads to serious injuries of the head and neck. It’s also the leading cause of severe injuries in football,but remember the protection of legal equipment doesn’t depend on its quantity.
Get good training. Players should learn the right way to use a tackle (装备). 5. Correct training could lower injury for younger players. Older players could be at a greater risk of injury if they first learn to use tackle and never learn the correct skill.
A. Take steps to lower football injury.
B. Weigh the risks and benefits.
C. The more legal equipment players wear, the less injury they will get.
D. Legal equipment can give football players important protection.
E. Players should know what to expect from each other.
F. Doing this and practicing the skills often make sure players are correctly trained.
G. As players get older, stronger and faster, the chance of injury goes up.
Scientists are attempting to extract (提取) cells from a 40,000-year-old horse in hope of using the sample to clone the extinct (灭绝的) species back into existence. The male baby horse was discovered in 2018 in permafrost (永冻土) in northeastern Siberia of Russia.
A team of scientists from South Korea and Russia believes the young horse, called the Lenskaya or Lena horse, was about 20 days old when it died. The species of horse, now extinct, is between 30,000 and 40,000 years old. Thanks to the terrible coldness, the animal’s tissue was preserved enough for the scientists to obtain samples.
Semyon Grigoriev, head of the lab at the Mammoth (猛犸象) Museum of the North-Eastern Federal University in Yakutsk, said the horse was “well - preserved” and a “great find”. There is no damage to the horse’s body and even its hair is undamaged. The unfortunate animal, according to Gngo-riev, “could have drowned after falling into some kind of a natural trap.”
Hwang Woo-suk, a researcher from South Korea working on the project, said, “If researchers find a cell, they will do their best to clone the animal. If we get live cells from this ancient baby horse, it would be wonderful in terms of cloning.”
After that, they will make a cloned embryo (胚胎) and a female horse carry it as its mother. Hwang said modern-day horses are “very similar to the ancient one,” so there would be no problem getting help from a modern-day female horse.
The scientists are hoping the experiment on the baby horse will give them experience in progressing toward their ambitious goal-bringing back the extinct woolly mammoth.
“If we manage to clone the horse-it will be the first step to cloning the mammoth.” Hwang said.
1.Why was the Lenskaya horse kept in good condition?
A.The temperatures were extremely low. B.It was buried under the ground.
C.Alocal museum had preserved it. D.It died quite young.
2.What do we know about the baby horse?
A.It was a female horse. B.It might have died by accident.
C.Its hair was partly destroyed. D.Its tissue can hardly be found.
3.What must the researchers do before cloning the extinct horse?
A.Know more about extinct ancient horses. B.Make an embryo i a female horse.
C.Find an ideal modern - day female horse. D.Get live cells from the baby horse.
4.What can be the best title for the text?
A.A new horse species found in Siberia B.How to preserve ancient animals’ tissues
C.Scientists attempt to clone extinct horse D.How to extract cells from extinct species
Laughter is a kind of universal body language that is shared by people of all nationalities, skin colors, cultures and traditions. But did you know that the ability to tell real laughter apart from fake (假的) laughter also varies among cultures?
Greg Bryant, a professor of communication at the University of California, published a study in late July. In the study, 884 people from 21 countries were asked to listen to random recordings of laughter. Some of the recordings were made up of laughs from the bottom of the heart, while others were made by people who were asked to laugh on command.
The study showed that people around the world have the ability to pick out real laughter, although their abilities vary from country to country. Residents of the Samoan Islands, were particularly good at it, correctly identifying real laughter 56 percent of the time. According to Bryant, people from smaller, less industrialized nations “are more accurate in identifying a natural smile” because they rely heavily on emotional engagement in order to predict others’ behavior and create stronger social relationships.
But how do people from different cultures detect natural laughter so easily? And what characters does real laughter have? As Professor Jessica Wolf of the University of California told the Association for Psychological Science, in real laughter, we produce qualities, such as higher pitch (音调) and volume, as well as faster bursts of no clear sounds.
By contrast, fake laughter will “sound like speech”. According to Science Daily, fake laughter is controlled by the same brain system that controls the lips and tongue. Bryant further explained that this system has active ability, saying “with this speech system, you can make a lot of different noises, including crying, laughter or scream. That’s where fake laughter comes from”.
So that? s something to think about: next time one of your friends laughs at something you say, will you be able to tell if it’s real or fake?
1.What did the study find?
A.Real laughter is produced from people’s heart.

2.Why are residents of Samoan accurate in identifying natural laughter?
