3 . A new study of parental attitudes, Growing up Digital, by the UNSW Gonski Institute of Education found that 83 percent of carers, parents and grandparents thought their children were negatively distracted by their devices.

Parents are worried that being on a screen stops their children doing other activities, such as being physically active and playing outside, being creative or pending time connecting with friends or family. Many are concerned about the dangers of cyber-bullying and the effect of social media on their children’s mental and physical health.

Over the family dinner table, the most common argument is increasingly about use of mobile phones. Three-quarters of parents say it is hard to control their children’s use of their digital devices and two-thirds say the topic is a source of conflict in the home. Teachers are saying the same things about behaviour in classrooms.

While the digital world is not without its dangers and challenges, some experts warn parents against demonizing smartphones or social media.

The more extreme fears about the impact of the digital world on the current generation of children will likely sound as outdated in a few decades as when their great-grandparents inveighed against the evils of television or rock’n’ roll music.

Many previously sceptical parents have seen the positive human value of social media during the COVID-19 pandemic because it allowed their children to connect with friends and family through lockdowns and social distancing. Children could keep up their education remotely.

Rather than railing against the digital world, parents need to think of strategies to help their children get the best from their devices.

Parents should talk to their children about how to use their devices more productively and safely. They should accept that the online world can be creative and a source of inspiration and connection as well. They should give children positive reasons to limit their usage rather than simply telling them to put them phones away.

It is not possible to turn back time and stop children using their devices. Parents and teachers must help children get the best out of them.

Old people who smoke may think     1     unnecessary to give up the habit as the damage from years of smoking can't be made up for. But it turns out there's a benefit of     2     (quit) even later in life. Recent research     3     (publish) in the American Journal of Preventive Medicine found that older adults who quit smoking in their 60s     4     (have) a lower chance of dying in the following years than the ones of the same age who kept smoking.

The results were based on a survey     5     more than 160, 000 participants older than 70 completed questionnaires about their smoking history in 2004 or 2005, and were tracked until the end of 2011 to see who had died. Those who quit in their 60s had     6     23 percent lower risk of death during the study than the current smokers.

The research also stresses that the most effective way     7     (keep) from smoking is to advise people not to get     8     the habit in the first place. Most smokers start and get both physically and     9     (mental) addicted during their adolescence. And among current smokers, the     10     (early) the study participants started, the higher their likelihood of dying during the follow-up period.

5 . On May 7, 2008, three men robbed a bank in a city called Waldorf of Maryland in the USA. They drove away in a van with a bag of money. They thought they had escaped. But the bank had put a pack of chemicals in the money bag, and the pack exploded.     1     Soon afterward, the police arrested one of the robbers. How did the police find him so quickly? DNA from the robbers’ blood was found on the bag of money.

DNA consists of genetic material that is found everywhere in our body, such as in our blood, skin, and saliva. It is our genetic fingerprint. All people have similar DNA, but no two people have the exact same DNA.

    2    The testing works like this: After a crime occurs, the police collect evidence from a crime scene. Some of this evidence may be DNA samples, such as hairs or blood.     3     The database is computerized, and it has millions of DNA samples in it. These DNA fingerprints are taken from people all over the country who have been arrested or convicted of crimes. If the DNA in the evidence matches someone’s DNA fingerprint, that person is probably guilty of the crime. But if the evidence does not match, the person is probably innocent.

    4     If DNA evidence is not collected or stored properly, for example, the tests may give wrong results. But it is still more reliable than other types of evidence. Witnesses may identify the wrong person. Lawyers, jurors, judges, and the police can make mistakes. DNA testing is usually accurate.     5    

6 . A Virginia teen is doing his part to make sure frontline health care workers are getting the meals they need to help them take care of themselves and others.

Arul Nigam, 17, of Tyson's Corner, Va. , has had to make several adjustments since his school year ended abruptly in mid-March due to the coronavirus pandemic(新冠疫情）。“We didn't have any classes for like over a month and then after that there were a lot of technical difficulties. So I started to have a lot more free time,” he tells Yahoo Life. “It was really saddening, but it was also something that really surprised me, that our health care workers are facing something like that,” Nigam says. “So I wanted to see what I could do to help them because obviously, they're sacrificing so much and giving so much for all of us. ”

In late March, the teen started fundraising efforts with the help of friends and family to help these health care workers receive much-needed meals. He also began doing research about what hospitals had the most amount of coronavirus cases, so he could prioritize those places first. He was also arranging for the orders to be fulfilled at local family-owned restaurants impacted by shutdown orders. So far, Nigam has delivered over 1,000 meals to 22 hospitals in 13 states, including New York, Massachusetts and Maryland.

Nigam's efforts have not only helped health care workers, but restaurants as well. With quarantine restrictions taking a toll on the food industry, places like Best Coast Burrito in Oakland, Calif. , have lost business over the last few weeks. Best Coast's owner,Alvin Shen, tells Yahoo Life that being able to partner with Arul and others in efforts to feed those on the frontline has been a big help.
