如今边走路边玩手机的“低头族”随处可见。请你根据下列图片的先后顺序，为校刊“英语园地”写一篇短文，谈谈使用手机的利弊及你的建议。
Nowadays，mobile phones are very popular. They are playing an important role in our life. We can use them to read news，send messages，make phone calls and read all kinds of books. Besides，we can use them to enjoy music，do some shopping and play games. In a word，mobile phones have made our life more colorful.
However，they also bring us many problems. For example，if people use them while riding，they may have traffic accidents. If we spend a lot of time on the mobile phones，it may affect our study. What“s more，they”re bad for our eyes and necks.
In my opinion，we shouldnt spend lots of time on them and we should use them properly.
今年是学习雷锋五十周年纪念日，雷锋同志说过：“我要把有限的生命，投入到无限的为人民服务之中去。”
请写一篇意思连贯，符合逻辑，不少于80字的作文。
在作文中，简单表述你对雷锋的崇敬之情，为什么向雷锋叔叔学习以及你在日常生活中是如何帮助他人的。
Leifeng was known as a pattern that offered help to others selflessly. He devoted all this life into his beloved career as well. I， myself， was totally shocked by his character.
Such is human nature； people trace the good， water flows to low. Everyone should copy his sprit as our daily life goes instead of uttering a meaningless slogan “learn from Leifeng， our decent idol” so that we could definitely see a lot more smiling faces rather than conflict.
To help others is not a hard thing， however， what you need is to consist doing it. Take myself as an example. I am the representative of Math， to collect homework is my daily task， however， I would turn them to the right page for shorten the time for teachers when correcting them.
I strongly propose that we shall see a better world if each of us treat Leifeng as our model and copy his spirit.

Dear Jim。
Im writing to tell you more about the new form of sharing bike--mobike mentioned in your latest letter.
Its very convenient to use if you have a smartphone. What you do is to find a nearest mobike through the APP， scan the QR code on the bike， and enjoy your trip.
Compared to other forms of sharing bike， the greatest advantage of mobike is that you can easily find one and never worry about where to park it. It is becoming a new trend as a means of transportation， which relieves the traffic pressure and does good to the environment as well.
Hope to ride a mobike with you in China.
Yours。

雷锋
雷锋（1940年12月18日－1962年8月15日），原名雷正兴，中国湖南省长沙市望城县人。共产主义战士。他1954年加入中国少年先锋队1960年参加中国人民解放军，同年11月加入中国共产党。他克己奉公，助人为乐，为集体、人民做了大量的好事，荣立二等功一次、三等功两次。1962年8月15日，伟大的共产主义战士雷锋同志因公殉职，年仅22岁。因雷锋热于助人事，所以雷锋二字已在中国内地经成了“好人好事”的代名词。毛泽东于1963年3月5日亲笔题词“向雷锋同志学习”，并把3月5日定为学雷锋纪念日。
