英語作文課間聽音樂的利弊
也可以是聽MP3的利弊

The beginning of the 21st century see the rise of portable entertainment utilities ranging from game devices to music players，playing a more and more indispensible role in modern people's life，especially forteenagers.Itis widely seen that students with their earsets on all the time，even atschool.Howeverthere are always disputes ensuing sucha new trend.
Listening music after class，though preferable to most students since they offer a contrast，comfortable experience against vapid and dull classes，does little benefit tohealth.Statisitcshave shown that overexposure to music，especially with a inappropiately adjusted volume，would result in eternal mayhem in people'shearing.What's more，the widespread fashion of rock，pop and dance music，whose energetic rhythms enthrall most young people，would largely distract students' concentration from their classes.
Maybe the best compromise is the proper selection of music style（light，classical music does appear far better for your hearing protection），prudent constrain of time spent on listening to music and other moderate control of sets like volumes，so as to satisfy teenagers' appetite and avert substantial impact on their health and study.

英語翻譯
A lot of people go though life with only a fewfriends.Itseems that some have fewer thanthat.Theyhave no one on whom they can call in good times orbad.Thereis no one with whom to bounce ideas around，or to talk about deep and troublingsubjects.Theyhave no one to call in times of needdifficulty.Theyare at the mercy of life，standing alone.
Friendship is a blessing，and a friend is the channel though whom great emotional，spiritual，and sometimes even physical blessingsflow.Friendscan cheer us when we’re sorrowful ordepressed.Friendscan challenge us when we allow ourselves to get beyond our reasonableboundaries.Friendscan motivate us when we’re ready to give in，and they can provide for us when life fallsapart.Theyare there when all is well，and we want someone with whom to share life’s pleasant and memorablemoments.Weoften just want them around to have a good time，to laugh，to act silly，to enjoy some mutually likedactivity.Inhow many ways have friends enriched our lives and made us feel loved，accepted，respected and cared for？Probably，too many to list，and the list grows daily.

很多人此生只有很少朋友.看起來有的人更少.是好是壞都沒人可傾訴.沒人在身邊給他們出主意，也沒人和他們談心.他們身處困難卻無人可援，註定是悲慘的生活，孤獨一生.友誼是種福氣，朋友多了路好走即使你物質精神都富有.朋…

我的愛好、理想作文（100字）

今天天氣真不錯.下課了，同學們陸續走出教室，來到操場上做遊戲.
今天天氣真不錯.下課了，同學們陸續走出教室，來到操場上做遊戲.
我和同學們做起了捉迷藏的遊戲.我躲在山茶花後，我想：我今天穿了紅色的運動服，又戴了紅領巾和紅髮夾，其他同學一定找不到我！果然，找我們的小瑩怎麼也找不到我們，我透過山茶花的空隙，發現她正朝我這裡走來！我又想：遭了，該趕快轉移目標.於是，我和小菁、小藍慢慢的移動著，不一會兒，我們又移到橘子樹旁，幸好小瑩沒看清，否則我們都難逃此劫！小瑩忽然靠著學校的宣傳欄站定，忽然喊道：“小雲！老師找你開會！”只見躲在竹林裏的小雲跑了出來，她一下子就被小瑩捉住了！
該我了，我先到我經常藏的地方找找，嘿！沒有.這時，我透過紅領巾，看見圓圓在演出臺上手舞足蹈.我氣壞了，直奔演出臺，把圓圓抓住，她問我：“我服了你了，你怎麼抓到我的？”我得意洋洋地回答：“就你？在演出臺上手舞足蹈，紅領巾那麼薄，我當然看得見！”這回，圓圓可算是心服口服了.要知道，她可是難得說別人一句好話！
叮鈴鈴……上課了，可操場上仍然回蕩著我們快樂的笑聲……
