Task 7: Why do we research the whales except the reasons mentioned in the listening script
① To Monitor Threats;
②To Track Movements;
③To Understand Intelligence;
④To Ensure Coexistence: Ultimately, the knowledge we collect enables us to safeguard whales and foster a balanced coexistence. By protecting them, we help maintain the health of marine ecosystems—which whales play a crucial role in—ensuring the stability and sustainability of our shared planet. A healthy ocean ecosystem is essential for all life, including humans. All in all, we should live in harmony with them (animals).

The Whale Research Camp(词数89)
My experience at the whale research camp was both educational and exciting. (主题句)
First, we went out on a boat to track a group of whales. (论点阐述) Then, we took pictures of their fins because their unique marks help us tell them apart. (论点阐述) We also noted their locations carefully. All this data was added to a database to monitor whale populations and understand their movements. (阐述目的)
This hands-on experience taught me the importance of marine conservation.
(总结句)
Sample answers
A Day as a Whale Researcher (词数132)
(句子功能:主题句) Participating in the whale research camp provided me with invaluable insights into the world of marine biology and conservation. (句子功能:论点阐述)
Our fieldwork began with tracking a group of whales by boat, a truly breathtaking experience. The core of our work involved data collection techniques, such as photographing their fins and noting their precise locations. (句子功能:阐述目的) This process is crucial because the unique fins allow researchers to identify individual whales, while the location data helps in plotting their migration paths. (句子功能:论点延伸) Later, we contributed to a global effort by creating a detailed database and sharing our findings with international research groups. (句子功能:总结与情感升华)
Through this, I realized that marine mammal research is not just about observation; it is a vital tool for protecting endangered species and ensuring the health of our oceans for future generations.

Saving the reef
With so much to see in the crystal, clear waters of Australia’s Great Barrier Reef.It’s no wonder that millions of people visit it every year. In addition to tourism, it is a major site for fishing, research and shipping.Yet more than half of the reef’s coral has been lost since 1985.And human activity is largely to blame. Industry along the coast pollutes its waters.While illegal fishing is reducing the number of fish, but the biggest threat may be climate change caused by human activities.Rising water temperatures bleach the coral, not only causing it to lose its rainbow colors.But killing the algae it needs to survive, climate change is also making the water more acidic.Causing coral to grow more slowly. Fortunately, long term plans are now in place to try to combat the effects of climate change.The Reef became a UNESCO World Heritage site in 1981 and today is carefully monitored.Areas of the reef where living things reproduce and now protected.And measures are being taken to stop tourists and fishing boats damaging the reef further.The islands around the reef are also protected from fire and pests.Through actions such as these, it is hoped that the Great Barrier Reef will be conserved for future generations.

Initiative Name: The “Coral Guardians of the Future” Project
Problem Focus: The Great Barrier Reef is losing its coral at an alarming rate. Climate change is
causing bleaching, turning vibrant ecosystems into white graveyards.
Key Threats: Climate change (leading to warmer waters) and pollution.
The Solution: We propose creating an online platform where schools and individuals worldwide can
“adopt”a piece of coral. Donations will fund new coral growth in protected nurseries,
and donors can track their coral’s progress online.
Slogan: “Act Now, or Admire Later in Pictures.”

Problem Focus: Plastic pollution is choking our reefs, harming marine life and damaging coral ecosystems.
Key Threats: ①Plastic waste entanglement and ingestion
②Microplastics contaminating the water
③ Climate change exacerbating the problem
The Solution:We will launch community-led monthly beach clean-ups and install special waste collection
bins along coastal areas. Simultaneously, we'll develop an educational program for local
schools and tourists about reducing plastic use. We also plan to work with local businesses to
promote alternatives to single-use plastics.
