你好，我是外贸助理的。 一：想要多提高口语的话，首先第一个是提高你的听力能力，这里有一个办法，只是建议，可以根据自身情况，自己决定。在睡前半个小时，请用耳机，静下心来听听力，基本半个钟到一个钟头就可以了！每天都坚持听一下，反正你都要睡觉了，别说那时候你还没空，听不懂的隔天再听一次，听到懂为止。 二：口语要多说的，所以找个好友，或者找个foreigner来进行沟通，有时候一句话，可能说之前要想一下，说多了，思维转换能力就能得到提高，很快就能反应过来了。根据你说的条件，因为本身不是很喜爱英语的话，也不会说特的去说英语，但是有些网是专门提高一些爱好英语的人，有联系方式，可以加他们！联系他们的！steven-do@hotmail.com 这是我的MSN，欢迎随时沟通，呵呵。 三：一般做翻译的话，至少也得专业四级以上，但是很少专门只是翻译的！还是需要做其他事的，这个你要知道。这个的话，可能职位会比较少点，但是外贸这行还是很多职位的。也是经常用到英语的。 四：其实你说你想要练习口语，建议可以看些场景常用的对话吧！因为基本上跟国外的人说话的时候，也不会很难的。不过有些地方，像中东这边，说话可能你会听不清楚。多看些BBC新闻之类的，会对你有帮助的！看电影也可以呀，在你说口语之前，听力是最最最重要的，你听懂了，但是用了多长时间，思维转换能力够快吗？ 以上只是本人一点见解，希望对你有用。加油···

In today, plastic products in our daily life accounted for a large proportion and competition in the market is very encouraging showing intense today, people living in the commonly used items design become a very important link. With the people's living standards improve a lot of people to buy a tablet PC, and whether it is aged middle-aged or young people tablet used in people's daily life with increasing frequency, so the design of a tablet computer bracket can make people's life more convenient and comfortable. The appearance of the tablet PC support is relatively high, the overall volume is large, the structure is complex, so the mold and the injection molding process is very demanding. The biggest difficulty in the tablet PC is how to make the bracket shell and the contraction rod fixed and can rotate. This design to the size of the size of the tablet PC for the design of the mold size considerations, and to the design of injection mold design program step by step design, the whole process reflects the relevant knowledge of mold injection molding. Design Tablet PC support mold, I used CAD in the early production of plastic parts of the overall three-dimensional picture, but also draw a tablet PC support assembly mold of the various three views, assembly drawing. And the structure of the plastic parts of the process analysis, clear design ideas, determine the injection molding and detailed calculation verification and injection molding process. Finally, through the injection mold design of the tablet PC support, I consolidate and deepen the knowledge of the school, and achieved satisfactory results, to achieve the desired design intent.
