Just a few seconds of frenzied passion on the floor of the public bar and things would never be the same again for Michelle. It only took a few minutes to ruin her life. The end of all her hopes and dreams, her childhood and teenage innocence, all stripped away the first and only time she ever surrendered herself to a man.
No one saw it happen, but the news spread fast; it wasn't long before the whole of Britain knew what had happened in the Queen Victoria -- Dirty Den, the landlord, had done it again. Only this time he had gone too far.
For the millions who have agonized with her, Michelle's pregnancy seems a terrible price to pay for one mistake -- a little youthful stupidity. Yet, with the increasing number of teenage single mums, it's not just a problem dreamed up for a soap opera -- as actress Susan Tully, who plays Michelle, has discovered from hundreds of letters: It's a dilemma many young girls face.
As she talks about Michelle and her baby, it's easy to understand why Susan has been so successful in the role. Even though she's never had an experience like it herself, it's one she recognizes all too clearly from what happens to some of her contemporaries at school. Michelle might almost be her younger sister rather than a fictional part in Britain's most successful soap opera.
Susan says that she never became involved with men during her school years because of her work. With her time being split equally between school and television studios, she was busy learning lines while her girlfriends were dating boys. While they went out to discos and parties in the evening she was desperately catching up on her schoolwork.
"I don't feel as though I've missed out on anything," she insists. "And unlike a lot of my friends, I've got plenty to look forward to. That's what's so nice about my boyfriend now. It's very comfortable and there's lots to find out about each other."
"It's then that I feel sad for Michelle. When she should be going out and having fun, she's having to worry about whether she's going to breastfeed the baby. Sffe's had to say goodbye to being a teenager."
How did Susan avoid the dangers that many of her school friends faced?

A. By thinking of Michelle as her younger sister.
By doing many projects at home.
C. By working hard at school and at TV studios.
D. By dating her boyfriend during her school years.

半导体:是导电性能介于金属和绝缘体之间的物质。根据这个定义,下面说法错误的是()。A.某种溶液的导半导体:是导电性能介于金属和绝缘体之间的物质。
根据这个定义,下面说法错误的是()。

A. 某种溶液的导电性能不如金属,又不是绝缘体,所以,这种溶液是半导体
B. 汞的导电性大但小于铝、铜、铁等金属材料,所以,汞是半导体物质
C. 干燥的木块不导电,将木块弄潮湿后开始导电,但导电性能远不如铝、铜等金属材料,有人说,“潮湿将木块由绝缘体变为半导体”的说法是错误的
D. 在纯结晶状态的硅中掺入某些元素原子后,会由不导电变为导电,但它在某一个方向导电比另一个方向容易些,而且导电能力受电压等外界因素影响大。这些导电性能不如金属,所以,硅是半导体物质
