Internet英语课件
What’s more, the Internet offers an alternative for the employees. Some businesses are starting to allow their employees to work at home for two to four days a week, sending their work in via e-mail or a direct connection to their company's intranet. In addition, I benefit a lot from the Internet in a personal way. I can still clearly recall the situation when I first came into this university. In such a big city, in such a place far from home and relatives, I felt quite lonely and was depressed. It was Internet that brought me and my parents together. I could see them through the web camera and chat with them. They encouraged me to be stronger and adapt myself to the environment. That’s the reason why I am now living a happy life here on campus.

便在脑海中幻想着自己亲手 制作小木雕的场景，迫不及待的想要把它们变成现实。 幻想着自己成了能工巧匠，一块木头不一会儿就被做成了一只栩栩如生， 非常可爱的小狗。忽然感觉自己就 好像是＂神笔马良＂一样，也拥有一把神奇的 雕刻笔，相信任何木头都能让它变得形态逼真，活灵活现的。 我将去年暑假收集的雪糕棍全部找了出来，用铅笔和直尺开始了绘图，我 想要做一把 小木剑：用直尺量出了木条宽的中点，又在两边找到了两个合适的 点，平移做成了一个长方条，和刚才的点连接后，剑的大致轮廓就做出来了， 剑柄也在十分钟后完工。 这一切都进行的顺顺 利利，我便开始了雕刻，每一步我都小心翼翼的，可 我担心的事还是发生了，因为木条的木纹是倾斜的，所以正当我雕刻时，一不 小心就顺着木纹切了下去，把木条切断了，这一个小小的失误 使得我前功尽弃， 还险些伤到了我的手指。 我有些退缩了，毕竟以前曾两次被小刀割伤过，但想到那些雕刻大师，他 们从小就开始练习，经过多少次伤痛才能拥有今天的成果，累累伤痕见证 着他 们的辛苦付出，也是成功的必经之路。和他们相比，我的这些困难又算得了什 么。 想到这里我又重新鼓起勇气，拿起铅笔从头开始，计算、绘图、修改…… 开始雕刻时，我深吸一口气， 静下心来仔细的雕刻着，顺着铅笔的痕迹， 一点一点的雕刻着
