    Last summer holiday, I paid visit to Hong Kong with my father. To their surprise, we found the streets were not as wide as those in our city. The bus and cars were running very fast. The sidewalks were always crowding because many visitors went there every day. The people there were friendly, and when we were asked them for help, they were willing to help us. We take many photos there and then we shared them on WeChat Moments（朋友圈）. We also bought some gifts there for much things were sold for a discount. It's so hardly to say goodbye to Hong Kong. We hope to go there once more unless we have chances.

    "Cool" can be used to expressing a temperature that is a little bit cold or feelings of interest in almost anything. Sometimes we maximized the meaning of "cool". You can use it instead many other word such as "new" or "surprising". Here's an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall she had visited. On the one student's paper was just one sentence, "It's so cool." Maybe he thought it was the best way to show how he saw and felt. The story shows lack of words. With "cool", some people have no words to show the same meaning. Can you think of any expression made your life as colorfully as the word "cool"?

    Yesterday, I read article about the Hongkong Zhuhai macao Bridge, the longer sea-crossing bridge in the world. It is55 kilometers long, which lifespan(使用寿命) is set at120 years. And it can stand heavy storm and earthquakes. What's more, the travel time among Hongkong and Zhuhai is cut from 3 hours to just 30 minutes.

    After reading the article, I feel wildly excited. In my opinion, drive a car on the bridge was an enjoyable experience. Besides, my dad didn't agree with me, because she was not skillful at switching (切换 ) freely between Chinese driving and English driving. Though I can understand him now, but I do hope someday we can drive on the bridge.
