指示代词的指代含义该如何准确判断呢？

Step 3：结合语境做验证
下面来看几处例题，检验一下吧：
例1：C11T3P2-Q24
One particular population’s summer habitat is a national park, and their winter home is on the____ , where they go to avoid...
分析：
本题可以根据summer habitat, national park, winter home 等定位词，结合出题句特征（含有指示代词的句子），定位到下一句话：
One population, which spends the summer in the mountainous Grand Teton National Park of the western USA, follows a narrow route from its summer range in the mountains, across a riverand down onto the plains. Here they wait out the frozen months, feeding mainly on sagebrush blown clear of snow.
分析这句话可以得知：summer habitat替换为spends the summer in the mountainous，national park则替换为Grand Teton National Park of the western USA，winter home则对应替换为frozen month；由此可以推测指示代词here 指的是某个地点，上文中的地点有两处，分别为mountains 和plains，最后根据句意验证可以得出plains 为本题的答案。
例2：C11T3P3-Q39
The writer advises non-mathematical readers to perform___while reading the book.
分析：
本题可以根据non-mathematical readers, perform, reading 等定位词，结合出题句特征（含指示代词的句子）定位到下一句话：
You will turn these pages much more slowly than when reading a novel or a newspaper. It may help to have a pencil and paper ready to check claims and carry out experiments.
分析这句话可以得知：readers和reading对应的定位句中的turn these pages，结合出题句特征以及最后一个定位词perform被替换成了carry out，结合语境理解得知，it指代的是上文中看书这件事，由此可以推出本题答案为experiments。
总 结
雅思阅读中会经常出现代词，用于指代之前出现过的人、事、物等，作为常见的出题句特征之一，在阅读中可以帮助烤鸭们快速定位、判断出题句。
