2 . China is a great country with the largest population in the world. In order to solve the population problem, our government carried out one﹣child policy (政策)before. When it is carried out for some time, many people not only see its advantages but also disadvantages.

From 2016, two﹣child policy is put into effect. In my opinion, two﹣child policy is good. First of all, two﹣ child policy is the gift for some only child. For some families, maybe the parents are only child and they also can have only child. Besides the loneliness of their child, when their child grows up and they grow older, their child marry an only child girl, the burden(负担)on their child and his wife is too heavy. Their child and his wife have to take care of two couples. Usually, a young couple looking after an old couple is a little difficult. But if their parents have two children, they can share the burden of taking care of their parents. It would be much better. Secondly, two﹣child policy can guarantee (保证) the number of Chinese population.

All in all, one﹣child policy has been out of date. And two﹣child policy is needed and necessary. It can solve the problems of nowadays (现在)and the future.

3 . According to a new study from Oxford Economics, a rise in artificial intelligence will result in an increase in “income inequality” as they estimate that 20 million manufacturing jobs will be lost in the next 11 years. In China alone, there could be 14 million robots taking work currently done by humans by 2030. While in the United States, more than 1.5 million workers would have lost their employment to technology by 2030.

The report predicts the use of robots worldwide has increased to 2.25 million over the past two decades. The researchers said, “As a result of robotisation, tens of millions of jobs will be lost, especially in poorer economies that rely on lower-skilled workers, which will therefore translate into an increase in income inequality.”

However, the researchers noted how “robotisation” has the potential to boost productivity and economic growth. They predicted a 5.3 percent rise in global gross domestic product (GDP) in 2030.The report said, “This means adding an extra $4.9 trillion per year to the global economy by 2030(in today’s prices).”

The report remained positive about the use of automation and urged lawmakers not to sand in the way of robots in the workplace, despite the threat of job losses.

The researchers said, “These findings should not lead policy-makers to seek to prevent the adoption of robot technology. Instead, the challenge should be to distribute the robot profits more evenly by helping workers prepare for and adapt to the big changes it will bring about. Explore all policy options from training, initiatives (新方案) and new welfare programs such as universal basic income.”

4 . This morning, while tidying up my office, I found an open box of packaged chocolate cookies that I’d bought sometime last year. The use-by date had come and gone more than eight months ago. Curious, I took a small bite. They still tasted pretty good.

Welcome to the world of ultra-processed (超加工) foods. And we’re eating a lot of them. Ultra-processed foods currently make up nearly 60% of what the typical adult eats, and nearly 70% of what kids eat. They include everything from cookies and sodas to packaged breads and frozen meals, even ice creams. You might not realize you’re eating one, but look close and you’ll see many ingredients you wouldn’t find in your kitchen.

And a large and growing amount of evidence has consistently linked overconsumption of ultra-processed foods to poor health outcomes. “Too much of it leads to obesity and type two diabetes (糖尿病) and heart disease and cancer.” says Christopher Gardner, a professor at Stanford University, who has spent decades studying the links between diet and chronic disease (慢性病).

One reason ultra-processed foods likely lead to health issues seems obvious: They tend to be low in fiber and high in calories, salt, added sugar and fat, which are all linked with poor health outcomes when eaten too much.

Eventually, Gardner says the burden of making healthier food choices shouldn’t fall completely on consumers-especially when it comes to setting kids up for better health long term. “It does need the whole society to pay attention to this, to work together, including the food industry and the government, to be able to reduce the amount of ultra-processed food our kids are consuming in their day,” he says.

5 . Anxieties (忧虑) about children and reading are not unusual, but news that fewer than half of those aged between 8 and 18 admit to actually enjoying it — the lowest level since 2005 — should raise a red flag. The survey, conducted by the National Literacy Trust ahead of World Book Day last Thursday, also showed a worrying picture of growing inequality.

10% of 3,000 parents interviewed across the UK said they were too stressed to read to their child because of economic pressures. And the percentage doubled among those who described themselves as struggling with financial problems. However, the sales data for the last year, released by an organization called Nielsen BookScan, showed a 15% increase in the overall number of children’s books sold compared with 2019. If poorer families are spending less of the money invested in children’s reading, it follows that richer families must be investing more.

Therefore, what is to be done? At a time of financial stress, libraries have a key role to play. A positive sign that they are doing so came with borrowing figures for last year. Libraries are where children of all ages go to choose books for themselves, different from bookshops, which is always influenced by parents’ budgets and tastes.

This is why the libraries are such an important part of the reading ecology. However, libraries have long been in the frontline (前线) of cuts to public services, especially libraries in schools. While prisons in the UK have libraries, primary schools are not. The result, according to one survey, is that 14% of kids have no library space at all. This disadvantage is more serious in the north of England, where children’s reading scores are lower.

As Children’s Prize winner in 2021, the author Cressida Cowell wrote an open letter to the prime minister, Boris Johnson, calling for an annual investment of £100 million a year in primary school libraries. Her demand should be taken seriously, as it directly meets the needs of children most badly affected by the cost of living crisis.

7 . More and more teenagers are becoming unwilling to exercise worldwide. Australia, a nation that prides itself on its outdoor culture, is doing particularly poorly. It is currently ranked (排名) 140th out of 146 countries for teenage exercise levels. The data shows that 85%of girls are physically inactive compared to 78% of boys. In Australia, less than 1 in 10 teenagers aged 12 to 18 are meeting the recommended levels of physical activity.

The current guidelines and evidence show that teenagers should be doing at least 60 minutes of physical activity per day. This should include muscle and bone strengthening activities on at least three days per week, meanwhile limiting recreational screen time to a maximum of 2 hours per day.

Not being active can cause a range of health conditions leading to early adulthood and beyond. Adolescents may have decreased bone and cardio-metabolic (心脏代谢的) health which leaves them facing an increased risk of chronic disease (慢性病) in later life, including type 2 diabetes, heart disease, high cholesterol, and decreased fitness. If you’re not moving enough you’re also at an increased risk of being overweight or obese, with data already showing that 29.8% of teenagers (14-17) are classified as overweight or obese.

So how can we get teenagers to exercise more? Firstly, high schools should place more importance on lunchtime and allow 1-hour breaks that increase physical activity. We should also encourage teenagers to be active on their lunch break. Parents and guardians also have an important role to play and should aim to devote 1 hour a day to moving more. This does not need to be 1 full hour and can be broken down into two 30-minute parts. The most important factor is to identify your teenager’s interests and needs surrounding their physical activity.

Don’t be afraid to ask for help in finding a safe and fun exercise program. A qualified exercise physiologist or exercise scientist can help your child find a way to be more active that is suited to their needs, age of development, and interests.

8 . Twins may be more common today than at anytime in history. Researchers analyzed records from 165 countries and found a significant rise in twin birth rates since the 1980s, with one in 42 people now born a twin. According to the survey, the global twin birth rate has risen by one-third, on average, over the past 40 years.

“The trends are really quite striking,” said Christiaan Monden, a professor at Oxford University. “Over the past 40 years we’ve seen a strong increase in twinning rates in rich and developed countries. Globally, twinning rates have risen from nine to twelve per 1,000 births since the 1980s, but the picture varies from country to country. The greatest rises are seen in North America (71%), Europe (60%) and Asia (32%). In the UK, twinning rates rose about 62%. In the Oxford study, a decrease of more than 10% was found in only seven countries over the dates surveyed. “The absolute number of twin deliveries (分娩) has increased everywhere except South America,” Monden said. “In North America and Africa, the numbers have increased by more than 80%, and in Africa this increase is caused almost entirely by population growth.”

Raj Mathur, a doctor at St. Mary’s Hospital in Manchester, said, “It doesn’t surprise us that twinning rates have increased because the availability of assisted reproduction (生殖) has increased and also because women are slightly older when they have their first children, and both those things will increase the twinning rate.”

“The majority of twin babies are completely fine, but there is no doubt that a twin pregnancy (怀孕) carries greater risks for the mother and the baby. So when we can avoid it, we should avoid it. The principle we follow is simply summed up by the phrase ‘one at a time’,” Mathur said.

10 . Human activities have caused severe narrowness in over half of the world’s largest lakes in the past 30 years, causing risks to health, economies, and the environment, according to a study in the journal Science. The global decline in water storage equals to 17 times the capacity of Lake Mead, the largest lake in the U.S. Overuse of water for agriculture, development, and human-caused climate change are the main factors driving the decline, particularly in natural lakes. The accumulation of dirt and sand behind dams also contributes to the fall of water levels in lakes.

The findings showed “significant declines,” stated Fangfang Yao, the lead author of the study. “Roughly one-quarter of the world’s population lives in a basin with a drying lake,” Yao said. “So the potential impact could be significant.”

At least half of the decline in natural lakes was driven by human-caused climate change and overconsumption, which should remind water managers to improve protection and water efficiency, according to Yao. “If you know a lake is falling and that loss resulted from human activities, can we attach more importance to protection and improving water efficiency?” she said.

A climate change-driven drought and an ever-growing human thirst have continued to consume the two largest lakes in the U.S. Lake Powell and Lake Mead, which the Colorado River feeds. Lake Chad, one of Africa’s largest freshwater lakes which supplies nearly 40 million people with water, has shrunk (收缩) by an estimated 90% since the 1960s.

The United Nations regards access to safe drinking water as a universal human right, yet around 2 billion people lack access to it, and half of the global population experiences severe water shortage annually.

“Uncertainties are increasing,” said Richard Connor, the editor-in-chief of a U.N. water report published earlier this year at a press conference in late March, where world leaders met to try and find better strategies for managing the planet’s rare freshwater. “If we don’t address it, there will definitely be a global disaster.”
