1 . Under the background of the slow growth of its total population to 1.44 billion, China has seen a sharp rise in older adults over the past decade, solidifying the country’s rapidly aging pattern, the latest national census (人口普查) data shows. The population on the Chinese mainland increased by an average of 0.53 percent annually during the past 10 years to 1.41 billion, compared with an annual growth rate of 0.57 percent from 2000 to 2010, according to the 7th national census published by the National Bureau of Statistics.

“The growth of the total population has slowed down but remains at a steady pace,” Ning Jizhe, head of the bureau, said at a news conference. “Based on trends in recent years, China’s population will grow at an increasingly slow rate in the future while remaining above 1.4 billion.” The increasing elderly population has become a defining feature of the past decade.

Ning said an aging society will set the tone for China's population structure for a long time, presenting challenges and opportunities. “A graying population will pile pressure on supply of labor force and social services, as well as adding to families’ elderly care burden. But more elderly people could also motivate consumption of products and services targeting this age group, and advance the development of some technologies,” he said.

Ning added that those between the ages of 60 and 69, who are equipped with knowledge, experience and skills and are generally in good health, make up nearly 56 percent of all older adults. “Their potential to continue making contributions to society and playing a constructive role is big,” he responded to a question on the outlook for raising the retirement age and carrying out other potential measures aimed at addressing the aging trend. Some population economists also said the latest number and proportion (比例) of elderly are largely within predictions, and the aging trend will continue for a long time.

2 . A 2020 study by Balbix found that 99% of the people surveyed reused their passwords between work accounts or between work and personal accounts.     1    

For example, a 2019 study by Google found that 59% of the people they surveyed used a name or a birthday in their password. And 24% admitted using a password like one of these below: 1234, 12345, 123456, etc.     2     Since both personal and work accounts are accessible from the same device with the same password, it simplifies the work a bad actor has to do in order to breach (攻入) your systems.

    3     The NIST (National Institute of Standards and Technology) Password Guidelines are widely regarded as the international standard for password best practices. Following these guidelines—and insisting your employees do the same—will help protect you against threats from weak or stolen passwords. Password managers can simplify the work required for your employees to follow these guidelines.

It's more secure to require your employees to use more than one authentication (身份验证) factor to access mobile company applications.     4     They'd need to check on their identity with additional authentication factors in order to log in.

Finally, you can also perform passwordless authentication.     5     For example, in the event that a mobile device is stolen or accessed illegally, requiring a facial scan (扫描) or a finger scan as a primary or secondary authentication factor could still prevent unauthorized access.

Table tennis first     1     (appear) during Victorian England. Table tennis didn’t become a competitive sport until 1988. Now table tennis not only is a matter of competition, but also provides an opportunity for people to play together no matter what their ages are. There is a day for people     2     love table tennis to spread their love for the sport. It     3     (call) World Table Tennis Day.

The International Table Tennis Federation has taken table tennis to a     4     (complete) new level. ITTF tries to make table tennis popular around the world.     5     (achieve) this goal, in 2015 ITTTF created World Table Tennis Day to get people interested     6     table tennis. Since then it has been celebrating the day so that more people can learn about     7     sport.

World Table Tennis Day is celebrated by     8     (organize) activities in the streets, clubs, bars, schools, workplaces etc. People can register for all these     9     (event) on the Internet to join in the worldwide celebration. If you’re looking for other ways to celebrate World Table Tennis Day, you can choose to watch     10     (excite) table tennis games on TV on the day and tell your friends what day it is.

6 . Not too long ago, one of my daughter’s middle-school teachers told me that my daughter was spending a lot of time on her phone during class. This didn’t surprise me. I am a filmmaker and I’m making documentary (纪录片) “Screenagers: Growing up in the Digital Age” carefully because I know how strongly technology attracts youth and how confused we are about what to do about that.

This month, the screenagers team and I completed a survey of people who were interested in the topic of our film to gather data on middle-school phone rules. More than 1,200 middle school parents in the United States responded. Two striking findings appeared:

●55% of the parents said their children’s middle schools now allow cell phone use, with public schools being more likely than private schools to allow it.

●More than 80% of parents do not want their kids to use cell phones during school.

Recently, France announced it is banning cell phones in school for all students age 15 and under, starting next fall. From our survey, it’s not only parents who support “away for the day” policies, which require students to leave their phones out of reach — so does science.

We know that the frontal lobe (脑叶) — the part of the brain responsible for impulse (冲动) control — is not fully developed in middle school-aged children. When we expect kids to learn how to handle phone use in places like classrooms, we are setting many of them up for failure.

Schools prohibiting (禁止) cell phones saw student test scores improve by 6.41%, according to a 2015 study from the United Kingdom. In the US, administrators of schools that have adopted “away for the day” policies have reported improvements in students’ emotional well-being too.

It is time we should follow France’s lead and do what is best for our middle-school students today.

For many people in the world, food waste has become a habit: buying more food than we need at markets,     1     (let) fruit and vegetables spoil at home or taking more than we can eat.

These habits put extra pressure     2     our natural resources and damage our environment. When we waste food, we waste so much labour, effort,     3     (invest) and the precious resources that go into producing it, not to mention the resources in transporting and processing it. In short, wasting food increases greenhouse gas emissions and     4     (contribute) to climate change.

It's     5     urgent issue. In fact, tons of food is lost or wasted     6     (global) every day. The part of food that is lost from harvest up to, but not including, the retail level is called food loss. The part wasted at the consumer or retail level     7     (refer) to as food waste. We make this distinction to address those root     8     (cause) of this problem, a problem that everyone from farmers and producers to customers can help end.

Reducing food loss and waste is essential in a world     9     millions of people go hungry every day. When we reduce waste, we respect that food is not a given. It's up to us     10    (change) our habits to make not wasting food a way of life!
