Carbon dioxide 【小题1】 (release) through human activities such as destroying forests and burning fossil, as well as natural processes such as volcanic eruptions. The measurements by climate experts show 【小题2】 rising trend of carbon dioxide emissions. If this continues, our planet 【小题3】 (face) with further environmental disasters. 【小题4】response to this environmental issue, China is implementing significant 【小题5】 (policy) and measures to address climate change, aiming to restrict coal consumption, have man and nature live 【小题6】harmony, build a 【小题7】 (sustain) energy system, and advocate a moderate, green, and low­carbon lifestyle.

A new bill has been 【小题1】 (official） passed in the Philippines that requires students to plant 10 trees each before graduation. According to the details 【小题2】 (outline) in the bill, the rule applies to all students who are to graduate from primary school, high school, and college. Trees can be planted in 【小题3】 forests, reserves, urban areas, abandoned mining sites, or in communities.

Over the past decades, the Philippines 【小题4】（lose） more than 30% of its forest cover due to 【小题5】(legal) logging （伐木），but the new bill means that the younger generation can help to address the problem. Under the new rule, 175 million new trees could be planted by students each year. If only 10% of them survive, 【小题6】 means that 525 billion trees can grow up over the course of one generation.

In fact, this isn't the only positive rule 【小题7】concerns the younger generation. One school in India made its students 【小题8】(pay) their school fees by collecting, bringing to school, and recycling plastic waste that was lying 【小题9】 the town. This helped raise 【小题10】 （aware） of plastic waste in Asian countries. It also allowed more students to seek education and even helped the students to earn some money so they wouldn't have to rely on child labour for a living.

Many of us wonder 【小题1】 lies in outer space. 【小题2】(occasion), when we look up at   the night sky, we see stars, the twinkle of a moving satellite and a distant planet. 【小题3】 one thing we don’t see is the millions of pieces of junk filling up space.

The amount of space junk is increasing. Over the last few decades, a large quantity of satellites and rockets【小题4】(launch) into space, littering the cosmos (宇宙) as they go. The fear is that【小题5】 we don’t start taking this litter out of the sky soon, it will become a   significant threat to active satellites. Nobu Okada, CEO of Astroscale,【小题6】company   working on ways to clean up space junk, says “even a small paint fleck (微粒) has enough ability【小题7】 (blow) up other satellites.”

It’s clear【小题8】 a solution is needed so a celestial (天体的) deep clean can take place. 【小题9】 (look) to the future, like any litter problem, we need to look at ways of creating【小题10】   (little).
