Grandma is very lonely one day, I went to school in the morning, mom and dad go to work, my grandfather has also gone out to the park. Grandma leg is not good, is more walk leg ache, so grandma had to stay at home. Grandma do not work, just listen to music at home, so she didnt feel lonely, also have things to do.

People alive, be without music, without music, the world will be very pale, our life is monotonous, boring, so the music is very important to us.

音乐是一种美的享受，它使我陶醉，令我心情舒畅。有了音乐给人们带来了快乐!

小草听了音乐，会长的越来越茂盛，越来越绿。数木听了音乐会长的越来越高。人们听了音乐也有好处，可以减轻痛苦、疲劳，也可以把不好的心情变成好心情，还可以让人们快乐，让人们跟随着音乐跳起舞蹈来。

如果世界上没有了音乐，小草就听不着音乐了，就会枯萎。树木没有了音乐就不会茂盛，也不会长高。人们听不着了音乐，就会觉得自己很孤单、寂寞，会感觉很压抑。

就说爸爸、妈妈吧!他们一天上班，工作很辛苦，晚上回来听听音乐，放松一下心情，舒缓一下劳累一天的身体，也可以减轻疲劳。

奶奶一天很孤单，我早上上学去了，爸爸、妈妈上班去了，爷爷也出去逛公园去了。奶奶腿也不好，一走多了路就腿疼，所以奶奶只好呆在家里。奶奶没有事干，就在家里听听音乐，这样她就觉得不孤单了，也有事情干了。

人活着，就离不开音乐，要是没有了音乐，整个世界就会很苍白，我们生活也会很单调，乏味，所以音乐对我们非常重要的。

Since I was very small, I was very shy in the public place, so I always

avoided giving performance in front of so many people. Though I tried hard to

get over it in school, I still felt uneasy in the public place. When I came to

the job market, I realized that I must get over my fear, or I would lose my

stage.

I still remembered the horrible experience for my first interview. Early in

the morning, I got a called that I was given a chance to the job interview. I

felt so excited. When I came to the company, I found there were other six young

people competed with me, then I started to feel nervous. The employers asked us

to sit in the round table and introduced ourselves one by one. When it was my

turn, I lowed down my head and spoke in low voice. Then the employers continued

to let us give speeches in the stage. I lose confidence and made the horrible

performance.

This interview taught me a lesson that I must get over my fear, or I will

lose chances. So I practise hard and dare to stand in the stage.

Protecting the Environment

In the last several decades, our earth has been extremely polluted, such as air pollution, water pollution, noise pollution and so on. In recent years, the extreme weather becomes more and more frequent. Winter gets colder and summer becomes hotter and it rains more frequently. All of these warn us that protecting the environment is a serious and emergent event. As our general people, we should build proper lifestyle. We should pay attention to water and light saving. When we go out, we should firstly choose the public transportation. The most important is that we must realize that we can do a lot of things to protect our environment. Its our duty to make our home better. Let’s change from ourselves.

在过去的几十年里，我们的地球已经极度污染，比如大气污染，水污染以及噪音污染等等。近几年，极地气候越来越频繁。冬天越来越暖，夏天越来越热，还经常下雨。所有的这些都警示我们保护环境是一件严肃紧迫的事。作为普通老百姓，我们应该形成合适的生活方式。我们应该注意节约水电。出门的时候我们应该首选公共交通。最重要的是我们必须意识到我们可以做很多事情来保护我们的环境。使我们的家园变得更美好是我们的责任。让我们从自己开始改变。

Nowadays, there are many kinds of activities for people entertaining in their leisure time, especially in holiday, such as climbing a mountain, having a picnic, holding a party and so on. However, these recreational activities have its advantages but also bring some harmful influences to people’s lives.

First, to some extent, these recreational activities enrich people’s lives. Those who take part in different activities will not be easy to feel lonely or boring in their leisure time and live wonderful lives instead. Second, taking part in some group activities is a good form to strengthen friendships. For example, many students will hold a union to collect their old classmates or friends in winter holiday so that they have a common time to communicate with each other. Last but not least, such activities like climbing a mountain provide a good chance to do exercise.

However, these recreational activities also bring some problems at the same time. For one thing, taking part in too many these activities will increase the burden of themselves or their families because it is inevitable to spend some money in holding these activities. For another, some recreational activities have potential harm for participants’ health, particularly staying up all night, drinking and smoking.

Therefore, in my opinion, we have to make a careful consideration before we take part in these recreational activities.

Today is Halloween, we put on all kinds of masks, dressed in colorful clothes, go to school to participate in the activities.

There, the foreign language teacher came in like a ghost, dressed in white and flawless clothes, with white powder on his face. The foreign language teacher flounced like a beast, and frightened us around. The foreign language teacher saw us so scared that we could not help laughing. The foreign language teacher also showed us the dishes. When I was talking about it, the foreign language teacher ran behind me and screamed "ah..." I am scared pale.

In the afternoon, the foreign teacher introduced two people to us, one is Millie, she dressed up like a little witch. There is a white ratio, he dressed as a doctor. They took out a large bag of sugar, spilled it, and fell down like a raindrop, and we rushed through the lightning speed to grab the sugar.

Time flies, in the twinkling of an eye on the school, looking at the filled pocket, I thought: This Halloween can be really happy ah!
