   Advantages of the location

   · the dolphins live in water that is 31_____ and full of sea life

   答案：clean

   原文定位：Its coastline remains largely undeveloped, which means the water quality is clean, and marine life is abundant

   同义替换：「full of sea life」↔「marine life is abundant」

2. · 32_____ are not allowed in the area

   答案：hunting

   原文定位：These waterways are among the few in the world where hunting is completely banned in these rivers, which means the dolphins and other wildlife are legally... yet another excellent reason to conduct research in Northern Territory

   同义替换：「are not allowed」↔「is completely banned」

3. Disadvantages of the location

   · severe 33_____ affects research

   · rivers are remote

   答案：weather

   原文定位：One major challenge is the extreme weather, which complicates research efforts

   同义替换：「severe」↔「extreme」，「affects research」↔「complicates research efforts」

4. Aims of the research

   · to classify the two types of dolphins

   · to find out if they are 34_____

   答案：related

   原文定位：So far, very few genetic samples have been collected from these species, so we also want to determine whether they are related

   同义替换：「find out if」↔「determine whether」

5. · to investigate where the dolphins live and their ideal 35_____ habitat

   答案：environment

   原文定位：Dolphins are highly sensitive to their surroundings, so understanding their preferred environment such as water depth, salinity, and food availability is crucial for conservation

   同义替换：「investigate where the dolphins live and their ideal」↔「understanding their preferred」，「habitat」↔「surroundings」

6. · to work out the 36_____ figures

   答案：population

   原文定位：Another key goal is to estimate their population sizes. Are these dolphins thriving, or are their numbers declining

   同义替换：「work out」↔「estimate」，「figures」↔「numbers」

7. · to examine their patterns of

   · to assess the impact of 37_____ activity

   答案：human

   原文定位：Finally, we need to investigate how human activities in their habitats affects them

   同义替换：「assess」↔「investigate」，「the impact of」↔「affects」

8. Techniques used

   · conducted boat-based surveys to help make a map

   · used photos to provide data on:

   - the 38_____ of the dolphin`s dorsal fins

   答案：colors

   原文定位：By photographing the colors and unique markings on their dorsal fins, we can recognize individual dolphins over time

   同义替换：「used photos to provide data on」↔「By photographing」，「the markings on them」↔「unique markings on their dorsal fins」

9. - the markings on them

   · took skin samples to find out:

   - their age

   - how much 39_____ they have been affected by the dolphins live in small groups, are long-lived and slow breeding

   答案：pollution

   原文定位：Skin samples using a harmless biopsy technique which help determine a dolphin's age. Further analysis can reveal their exposure to pollution

   同义替换：「find out」↔「reveal」

10. Further investigating

    · the effect of 40_____ on the dolphins (e.g., does it cause beaching?)

    答案：noise

    原文定位：For instance, I'm particularly interested in further investigating whether noise exposure might have negative impacts on dolphin populations. Questions like, could it disrupt their communication or even contribute to strandings

    同义替换：「the effect of」↔「might have negative impacts on」
