Dear Jenny,

    How are you? I am visiting my cousin Howard in Australia. It is hot in Hong Kong but it is cold in Australia in June. When it is summer in Hong Kong, it is winter in Australia. It is snowing heavily now. I like snow a lot and it is a white world outside. I will play with my cousin in the snow this afternoon. We want to make a snowman. I think it is very interesting!

    I like my cousin's house. It is big and there is a beautiful garden. We can play ball games there. My cousin's neighbors are friendly, but they cannot speak Chinese. I talk with them in English. See you next month.

Yours,

Tony

Einstein has to speak at an important science meeting.  On the way there, he tells his driver that looks a bit like him, "I'm sick of all these meetings. I always say the same things over and over!"

The driver agrees, "You're right. As your driver, I attend all of them, and even though I don't know anything about science, I could give the speech in your place. "

"That's a great idea!" says Einstein. "Let's exchange our places then!"

So they exchange clothes. As soon as they arrive, the driver dressed as Einstein goes on stage and starts giving the usual speech, while the real Einstein, dressed as the car driver, attends it.

But in the crowd, there is one scientist who wants to show off and thinks of a very difficult question to ask Einstein, hoping he won't be able to answer. So this guy stands up and cuts in the speech by raising his very difficult question. The whole room goes silent, holding their breath, waiting for the answer.

The driver looks at him, dead in the eye, and says, "Sir, your question is so easy that I'm going to let my driver answer it for me."

I went to Grand Canyon (大峡谷) National Park in July 2012 for the first time and I knew I wanted to work there as a park ranger（管理员）. Park rangers protect the park's animals, plants, land, buildings, and people.

Now, as a park ranger for Grand Canyon National Park, I share the science, history and beauty of this park with thousands of visitors from around the world.

National parks are like outdoor museums. Park rangers have all kinds of jobs, depending on where they work and what they studied during college. I teach school field trips（实地考察）, work at visitor centers and help people stay safe during their visit.

My favorite part of my job is showing children their first look at the Grand Canyon during school field trips. Children are often amazed at the canyon's size and colors. Sometimes, they think it looks like a painting.

Being a park ranger requires a lot of energy. I walk several miles and talk with hundreds of people each day. Park rangers must enjoy working with people and speaking in front of groups. Nearly 5 million people visit Grand Canyon National Park every year.

Park rangers must also be prepared for any situation. Recently, I broke a traffic jam(堵塞). It was caused by a huge elk（麋鹿）standing in the road. Elks can become dangerous when they get scared, so I asked visitors to stop their cars and take pictures from far away. Believe it or not, I also help protect people from monkeys. It is not allowed to feed animals in national parks. But sometimes, visitors try to feed monkeys.

    Want to be a hero? Better take a trip to the Great Wall. As the saying goes: You are not a hero1 you have climbed the Great Wall. As a wonder of architecture (建筑),it 2millions of tourists each year. Also, it is the most visited place for foreign leaders when 3come to China.

    The Great Wall has different sections (段)and each one is very 4 Jinshanling Great Wall in Hebei is 5 section. In spring, it is in the middle of a white apricot blossom (杏花林).6 summer time, green plants circle the wall. In autumn, maple leaves (枫叶) 7 a golden and red scene. And 8puts the great wall in a world of white snow.

    The "wild wall" is great for backpackers. Wild parts of the wall are for the adventurous (敢于冒险的人)9 they are the same as they were originally. Jiankou Great Wall is a famous one. Trees grow up from in between the stones. In some places, you have to climb the stones with both your hands and feet. Be 10when you visit the wild walls. You'd better not go there alone.
