新学期的第一天早晨，升旗仪式的'时候，三（1）班的一位哥哥和一位姐姐发了言。
On the morning of the first day of the new semester, during the flag raising ceremony, a brother and a sister of class 3 (1) made a speech.
从他们的发言中我知道了寒假中他们去了澳大利亚。他们学到了好多知识，学会了自理能力。还观赏了澳大利亚的美好风光。
I know from their speech that they went to Australia during the winter vacation. They have learned a lot of knowledge and self-care ability. I also enjoyed the beautiful scenery of Australia.
我很羡慕。我要好好学习英语，以后也想去澳大利亚！
I envy it. I want to study English well and want to go to Australia in the future!
