____________________________________________[范文]
As is known to us all, there will be a group dancing competition in our school next month. Of course, our class will not miss it. Our monitor called on all of us to take an active part in it.
Personally thinking, a group dance is quite a good form of entertainment as well as exercise, which brings us not only mental benefits but physical ones. Besides, dancing a group dance calls for teamwork, one of the qualities we will need for our future careers. Thirdly, by practising it, our classmates can develop a better relationship between each other, helping each other and encouraging each other. Last but not the least, this is a good chance for us to win honor for our class.
For all the reasons above, I have decided to join in it. I want to prove to be an honor to the class.考 点 探 究Ⅰ.重点词汇过关

阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词。
注意:每空格1个单词。
Greeting other people is the first and most important social event in our lives. Parents greet their children as soon as they are born, and it's not long before babies know who is who among the people in their everyday lives.After only a few months, babies work out systems of greeting for meeting people they know and those who are unfamiliar. Have you ever seen a four-month old baby staring at you? Have you smiled and said “hello” to the baby? Then have you watched the baby's little frown as it realizes that it does not know you? Either the baby will begin to make strange noises and cling to its caregiver, or it will jerk its head in such a way that its whole body moves, and smile at you.
The baby has learned to greet people and to respond to greetings at an very early age. What it has learned is the most important aspect of a greeting: the facial and body gestures that accompany the smile. These are signals that indicate friendliness.Secondly, there is the intonation(语调)in the voice. Greetings are said warmly, with an expression anywhere between bight quickness and easy-going friendliness.
The third aspect concerns the words chosen. Together, the words, the intonation, and facial expression signal a greeting. These indicators are the same all over the world.
There may be a little difference in the words used, but “Good day”, “ Bonggiorno”, “Nihao”, “Bonjour”, and “Guten Morgen” all contain the word “good”. The common greeting from other languages is translated into English as “Good day” or “hello”. “Konnichi-wa” means “good day”.There are thousands of languages and cultures around the world, but though the words are different, they mean the same. And they are accompanied with friendly gestures, with smiles and with pleasant vocal intonations. You learned all of these skills naturally in the first months and years of your life.
So please greet other people with a smile, warm voice and kind words. Please greet other people whenever you can and wherever you are.friendlinessothersaspects/ indicatorsmile warmchoiceGreetingsfrommeaningpossibl
