thầy cô và các bạn ơi, giải đáp giúp em với ạ. Em có học tiếng Anh trên mạng thì họ bảo thì quá khứ đơn diễn tả một hành động đã xảy ra liên tiếp trong suốt một khoảng thời gian trong quá khứ nhưng hiện tại đã hoàn toàn chấm dứt, ví dụ: She worked as a teacher for a six years b4 her marriage. Còn quá khứ hoàn thành là một hành động xảy ra trước một hành động trong quá khứ. Em thấy đọc ví dụ gioongs nhau quá, mọi người phân biệt giúp em với, em cảm ơn ạ

WIRES (Wildlife Information and Rescue Service) began in 1985 when someone found an injured bird in a park in Sydney, Australia. At the time, no one knew how to help this “native” animal. WIRES helps animals like snakes, kangaroos and, of course, birds. However, they can only help native Australian wildlife - animals that originally come from Australia. That means they can't help other animals like cats or rabbits that were brought to Australia from other parts of the world.

Like other animal rescue groups, WIRES needs more people. I believe they are definitely helping the local animals, but they can only continue if others join in. They hold excellent courses, where people can learn what to do when they find an injured animal. They also explain what happens to the animals in their care. Many of the people who help also take care of the animals themselves in their own gardens or on their farms.

I spoke to 15-year-old Guy McKenzie, whose dad helps WIRES in his free time. Guy told me about the work they do. “Dad usually gets a phone call at home and drives immediately to where the animal is, to rescue it. He has special equipment and always wears gloves. The animals are wild, after all!”

Guy also talked about a woman who found a bat in her garden. She thought it might be dead, but then she noticed that there was a baby bat too. Guy's dad brought it back to the centre, where it grew into a healthy adult. Then, WIRES was able to return it to nature. Guy showed me a baby kangaroo that his dad was looking after and told me that one day he'll be doing the same thing. Yes, he will, for sure.
