The oxpecker is a small bird that spends most of its time ___1___ on the backs of these large mammals. This might seem like a simple way to rest, but it's actually a classic example of a "symbiotic relationship," where both parties ___2___.

For the large animals, the oxpecker acts as a personal cleaner. The bird uses its sharp beak to eat ticks, flies, and other ___3___ that live on the animal's skin. This provides the oxpecker with a steady ___4___ of food. In return, the mammal gets relief from irritating bites and potential ___5___.

阅读下面短文，掌握其大意，然后从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。

Dolphins are known for their intelligence and playful nature, but their social structures are equally fascinating, built on strong ___1___. They live in groups called pods, which can range from a few individuals to hundreds.

Within a pod, dolphins cooperate closely for survival and social bonding.One remarkable behavior is how they care for sick or injured members.They will often ___2___ a struggling dolphin to the surface so it can breathe.This act of support shows a deep level of empathy and ___3___, ensuring no member is left behind.

Communication is key to their social life.Dolphins use a complex system of clicks, whistles, and body language to convey messages.They can even call each other by unique “signature whistles,” functioning like names.This helps them coordinate during hunts or stay connected in murky waters.Such sophisticated communication strengthens group ___4___.

Play is another vital part of dolphin society.Juveniles learn essential skills like hunting and social rules through playful interactions with peers and adults.They chase each other, play with seaweed, or ride waves.This playful learning fosters creativity and builds strong social ___5___.

Interestingly,dolphin pods sometimes form temporary alliances with other pods for specific tasks,like herding fish.This shows an advanced level of social ___6___ beyond their immediate family.

However,dolphin societies also face challenges from human activities.Pollution,noise from ships,and fishing nets can disrupt their communication,hunting,and social bonds.Conservation efforts are crucial to protect these intelligent beings and their complex social ___7___.Understanding dolphin friendships reminds us of the importance of cooperation,communication,and care in any community.

Our classroom has a set of rules we created together on the first day.One important rule is to ___3___ when others are speaking.This shows respect and allows everyone to learn Another rule is to come to class ___4___.This helps lessons start smoothly and ensures no one misses important information.

Of course,rules should be fair and reasonable.Good rules are not about control,but about creating ___10___ and protecting rights.When a rule seems unfair,it's important to discuss it ___11___ with teachers or leaders instead of just breaking it.

Living without rules is like trying to play a board game without ___12___—it leads to confusion and arguments.Rules provide a clear framework.They teach us about responsibility,consideration for others,and how to be part of a ___13___.So,while it's natural to sometimes feel ___14___ by rules,understanding their purpose helps us see them not as limits,but as the necessary guidelines that allow our community to function ___15___.
