1 . COVID-19 shutdowns forced people out of work and pushed tens of millions into poverty worldwide. Governments tried hard to provide aid. It was easy in a small country, but difficult for a country with large population and vast rural areas.
Researchers have been finding ways to identify areas of wealth and poverty in satellite images. Through some satellite data and aerial images of one town or another, you can sort of tell whether it’s wealthy or not. Wealthier homes tend to have metal roofs while poor homes tend to have thatched roofs. Wealthier neighborhoods have paved roads and bigger plots of lands, more spaced out.
The researchers use the system to identify about 60,000 people to receive benefits. The advantage of the satellite imagery and phone data approach is that it’s extremely fast and very convenient.
| A．It was opposite in a big country. |
| B．How do they locate the neediest people? |
| C．So there’s a lot of information in the images. |
| D．Most importantly, it’s very cheap to carry out. |
| E．Worse still, it’s not so economical as a house-to-house survey. |
| F．However, in general, poorer people will just have feature phones. |
| G．What the researchers did next was to target the neediest people in those regions. |

3 . Are you the only child in your family? If so, do you enjoy it or do you want more siblings（兄弟姐妹）?
On May 31, a key meeting of the Communist Party of China unveiled a policy that would allow all couples to have up to three children.
The move is expected to maximize the population's role in driving economic and social growth, since this is a critical time for China to transform the world's most populous country into a powerhouse（强国）with a quality workforce, according to the National Health Commission.
The three-child policy is also expected to prevent the decline in the nation's birthrate and address the challenge of a rapidly aging population, China Daily reported.
China's annual number of newborns has fallen for four years in a row. The country's total birthrate—the average number of children born to each woman—stood at 1.3 in 2020. The number is below the rate of 2.1 that would maintain a stable population, according to the National Bureau of Statistics.
The declining birthrate has also brought a sharp increase in the proportion of the population aged 60 or above, rising from 10.3 percent to 18.7 percent in the past decade. An increasingly elderly population will increase the cost of labor and the pressure on the social security net. It also means there will be a lack of young labor force. Therefore, it's not good for economic growth, according to Chen Youhua, a professor at Nanjing University.
In fact, the new birth policy is a step to further relax the family planning policy. The one-child policy was introduced in the 1970s and aimed to control the fast-growing population. Then in 2013, China allowed couples to have a second child if either parent was an only child, and in 2016, all couples were allowed to have two children.
However, not all people have shown their support for this latest policy. Many couples complained about the rising costs of raising a child. A netizen named Qinfeng commented, "High cost of education and both the physical and mental exhaustion stopped me from having more than one child." Also, many women are reluctant（不情愿的）to give birth because that could mean sacrificing their career prospects, according to Mu Guangzong, a professor at Peking University.
In that case, Mu noted that it is better to implement supporting measures with the three-child policy, such as more preferential（优惠的）policies for couples that would ease their parental burden.
