原文及修改：Well, the internal clock and the external clues are both important, which can determine the animal's 24-hour activity circle. Well, the internal clock and external cues are both important in determining an animal's 24-hour activity cycle.（将“clues”改为“cues”，将“circle”改为“cycle”，使表达更准确。同时调整句子结构，使其更自然。）

原文及修改：For example, take flying squirrels. For instance, consider flying squirrels.（将“take”改为“consider”，使表达更自然。）

原文及修改：Flying squirrels are active during the night and sleep during the day. In the experiment, some of the squirrels were kept in the constant darkness. Flying squirrels are active at night and sleep during the day. In an experiment, some squirrels were kept in constant darkness.（调整句子结构，使其更自然。）

原文及修改：This indicates that animals do have internal clues, which regulates their activity circle. This indicates that animals do have an internal clock that regulates their activity cycle.（将“clues”改为“clock”，将“circle”改为“cycle”，使表达更准确。同时调整句子结构，使其更自然。）

原文及修改：But when the internal clock is not priceless 24 hours long, instead of following the 24-hour circle, the squirrels follow the circles that were about half an hour shorter than that. However, when the internal clock is not precisely 24 hours long, instead of following a 24-hour cycle, the squirrels followed cycles that were about half an hour shorter.（将“priceless”改为“precisely”，将“circle”改为“cycle”，使表达更准确。同时调整句子结构，使其更自然。）

原文及修改：Well, after a month of the darkness, a month of waking up half an hour earlier each day, the squirrel activity circle has shifted a lot. After a month in darkness and waking up half an hour earlier each day, the squirrels' activity cycle had shifted significantly.（将“circle”改为“cycle”，使表达更准确。同时调整句子结构，使其更自然。）

原文及修改：So after that, the squirrel circles began to change. As a result, the squirrels' cycles began to change.（将“circle”改为“cycle”，使表达更准确。同时调整句子结构，使其更自然。）

Well, the internal clock and external cues are both important in determining an animal's 24-hour activity cycle. For instance, consider flying squirrels. Flying squirrels are active at night and sleep during the day. In an experiment, some squirrels were kept in constant darkness. They continued to have regular patterns of sleeping and waking. This indicates that animals do have an internal clock that regulates their activity cycle. However, when the internal clock is not precisely 24 hours long, instead of following a 24-hour cycle, the squirrels followed cycles that were about half an hour shorter. After a month in darkness and waking up half an hour earlier each day, the squirrels' activity cycle had shifted significantly. As a result, the squirrels' cycles began to change, and external cues like light and darkness eventually adjusted their internal clocks back to a normal 24-hour schedule.
