任务一 词汇运用
Dolphins are one of the most intelligent and kindest animals in the ocean. They use sounds and body movements to express their feelings, such as joy or worry. Scientists believe these sounds have special meanings, like a language only dolphins understand. Sadly, these amazing creatures face many dangers today.
In the past, people would hunt dolphins for food or fun, but now we know this is wrong. Pollution and fishing nets also make dolphins ill or even cause their deaths. To protect dolphins, governments and organizations begin to take action. For example, some areas have created safe zones where fishing is not allowed, giving dolphins a cleaner home.
What can we do? First, we should avoid throwing trash into the sea. Second, supporting groups that rescue hurt dolphins is a great way to help. Every small step makes a big difference because dolphins play an important role in keeping the ocean healthy.
Dolphins are not just animals—they are friends who teach us about teamwork and kindness. Let’s work together to ensure they swim freely in the ocean forever. Remember, protecting them is protecting our own future.
