It makes us convenient to communicate with each other. Today more and more students have a mobile phone. But some students use it in the school, even in the class. Do you think whether the advantages outweigh the disadvantages or the disadvantages outweigh the advantages?1.Every time you do you will be certain to find something that you have never seen before.
本句是一个主从复合句，其中every time在此句中引导时间状语从句；that引导定语从句，先行词为something。此句意为“每次你这样做的时候，你一定会发现你从未见过的东西”。
2．Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. 本句中含有重要结构：“祈使句＋and＋(表结果的)简单句”， 祈使句表示“条件”，简单句表示“结果”，通常用一般将来时。句型“祈使句＋and＋(表结果的)简单句”的意义为“干某事，那么就会……”；“祈使句＋or/or else/otherwise＋(表结果的)简单句”的意义为“干某事，否则就会……”，连词or可用 or else/otherwise替代。此句意为“跟踪下去，不断探索，不知不觉中，你就会发现某种值得思考的东西盘踞在你的头脑。”。3．One day as he was experimenting with one end of a straw joined to a deaf man's ear drum and the other to a piece of smoked glass, Bell noticed that when he spoke into the ear, the straw drew sound waves on the glass.
本句的主语是Bell，谓语是noticed，that引导一个宾语从句，在这个宾语从句中又有一个由when引导的时间状语从句；as引导一个时间状语从句，过去分词短语joined to a deaf man‘s ear drum作后置定语，修饰straw；the other to a piece of smoked glass是个省略句，可补充为the other end of the straw joined to a piece of smoked glass。此句意为“有一天做实验，他把一根干草的一端和一个聋子的耳鼓膜连接起来，干草的另一端与一块被烟熏过的玻璃相连接。贝尔发现，当他对着耳朵说话的时候，这根干草就把声波画在玻璃上”。4．But he found the problem difficult to solve. find＋n.(宾语)＋adj.(宾补)＋to do(to do作状语修饰adj.)是find＋it＋adj.(宾补)＋to do sth.(it是形式宾语，to do sth.是真正的宾语)的变式。此句意为“但是他发现这个问题很难解决”。
注意：“to do”形式中当“do”为不及物动词时，应在后面加上适当的介词。并且动词不定式使用一般式。例如：The man found the river dangerous to swim in.＝The man found it dangerous to swim in the river. 这个人发现在这条河里游泳很危险。

写作指导
求职信属于应用文中的书信类。写作时，要注意书信的一些基本格式。
首先，要注意开篇交代句、末尾总结句和常识性语句，提高文章的呼应性。开篇句往往交代得知消息的渠道，并表明求职心愿。如：I've learned from the newspaper that you are employing a… and I'm very interested in it.末尾句往往表达希望能很快收到答复的迫切愿望并表明感激之情。如：I would be very thankful if you would give me an early reply.Writing第二，求职信往往需要介绍自己的姓名、年龄、身高、健康状况、业余爱好、特长、工作态度及人际关系等。常见的短语有be in good health, be good at, be expert in, have rich working experience, enjoy doing sth. ，in one's spare time, be strict with, be kind to, get on well with等。
此外，要防止遗漏要点。如果是针对广告招聘的求职信，应认真阅读广告，明确招聘要求，并对照自己的条件，逐一加以介绍，同时还要注上自己的通讯地址和联系方式。注意：1. 篇幅不宜太长，要简明扼要。
2. 态度要诚恳，实事求是。
3. 所展示的信息要精炼且有针对性。
4. 语气要客气、礼貌。
