The Grand Canyon.
It was not just big. It was huge.
A great wonder of the natural world
When I arrived, it was early morning and it was raining. I looked to the east – the sky was becoming grey. I got out of the car, went through a gate and walked along a dark path. There was nothing to see, but I knew it was there.
After about a mile, a stranger appeared beside the path. “Am I going the right way ” I asked. He knew where I was going. “Yes,” he replied, “you’ll get there in five minutes.” Finally, I came to some rocks and stopped. I looked over them, but it was silent and there was no sign of it.
Suddenly, the rain stopped and the clouds cleared. The sun rose behind me and shone on the rocks. Far below me, the ground fell away and down to a river. I was looking across one of the wonders of the natural world - the Grand Canyon.
I looked down to the Colorado River, a silver stream nearly one mile below me. If you put the two tallest buildings in the world on top of each other at the bottom of the canyon, they still would not reach the top. Then I looked across to the other side of the canyon. It was about fifteen miles away, maybe more. Finally, I looked to my left and to my right, and on both sides the canyon went far away for more than 200 miles. The Grand Canyon was not just big. It was huge!
I remained by the canyon for about half an hour, and I asked myself, “Is the Grand Canyon the greatest wonder of the natural world ” I certainly know the answer. What do you think

知识点再现
在含有if引导的条件状语从句的复合句中，当主句、从句的动作都发生在将来，通常主句用一般将来时，从句要用一般现在时，即“主将从现”。如：
If you don’t hurry up, you will miss the train.
如果你不快点儿，你会赶不上这趟火车。
If I’m free, I’ll go to see you.
如果我有空，我将去看你。

The Great Wall
I visited the Great Wall last month. It was a sunny day. My mother and I took a bus and went there happily. But when we almost got there, it began to rain suddenly. We felt very sad.
As we went on our trip, it was raining harder and harder, we even wanted to give up. Just at this time, a long wall came into my eyes. What a huge wall it is!
The Great Wall is one of the great wonders of the world. It was built in the Qin Dynasty and it has a history of more than 2,000 years. It lies in the north of China. The wall is about 6,700 kilometers long and stretches from Shanhaiguan to Jiayuguan. The height of the wall is 7.8 meters, and its width averages out at around 6.5 meters at the base and 5.8 meters at the top. The Great Wall has become a symbol of the Chinese nation and its culture. I thought it was the most wonderful sight.
