2 . The world’s population reached five billion on the day I was born. That was in Indonesia back in 1987, and my parents was shocked that there were so many people on the planet.     1     In October 2011, the seven billionth baby was born, and experts predict that there will be ten billion of us before the end of this century.

    2     If you said “hello to a different person every second, it would take you 222 years to greet everyone on the planet. If seven billion people made a human chain with their hands, the chain would go to the moon and back nine times.

The human population has never been bigger, but in some ways the planet seems to begetting unbelievably smaller. In the past, travellers from Europe to Indonesia spent months at sea. Now you just have to sit on a plane for a few hours. When you arrived in another country a hundred years ago, you saw unfamiliar styles of clothing and buildings and discovered a completely different culture. In many places today, clothing and new buildings are very similar, and people enjoy the same things.     3    

Even the languages that we use are becoming more global. There are around seven thousand languages in use today.     4     I grew up in a small village where everyone spoke Baras, one of Indonesia’s local languages. Today, like most of the youth from my village, I live in the capital, Jakarta, and speak Indonesian there. The only regular Baras speakers at present are the older people who have stayed in the country, so the language is threatened with extinction.

A．But the number is decreasing fast.

B．Although we are on different continents, we are starting to live the same lives.

C．The planet might be a lot more peaceful if that were the case.

D．However, since then the population has continued to increase at an alarming rate.

E．A number as big as seven billion is hard to imagine.

F．With only one language left, there will be no culture difference in the world.

3 . 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.     1     Doing a detailed, nationwide, house-to-house survey takes people time and money. Luckily, satellites can see poverty from space.

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.     2     The researchers trained artificial intelligence (AI) to recognize these patterns.

    3     The researchers put AI to work studying patterns of mobile phone use in those regions. Rich people will make just more phone calls than poor people. They also might make more expensive international calls. They might use more mobile data because they have smartphones.     4    

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.     5     In shocks like climate disasters where there’s no time or way to get detailed information on the ground, satellites mobile phones and AI could help deliver aid quickly to people in need.

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.

5 . 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.

1. What might NOT be the main cause for the new policy?

A．To increase the population's role.

B．To stop the declining birthrate.

C．To improve the child- care service system.

D．To address the challenge of the aging population.

2. What can be known from the text?

A．China's annual number of newborns has fallen for decades.

B．The government will protect the legal rights of women in employment.

C．Measures will be taken to improve the high-quality education.

D．The new policy allows couples to have up to three children.

3. Which of the following can replace the underlined word "implement"?

A．To carry out.	B．To get along with.
C．To make use of.	D．To have a command of.

4. What is the author's purpose in writing the text?

A．To show his love of children healthcare.

B．To introduce the new family size policy.

C．To share his concerns about birthrate.

D．To emphasize the physical and mental exhaustion.
