請問我這個句子的語法對嗎?
First and foremost, no one could deny that the Internet, which was created by the rapidly developed science and technology, is the most convenient way to communicate among people. Since the Internet was invented, we can send e-mails to our friends within some seconds. We could keep in touch with our families wherever we are. Before the Internet was came, it is hardly communicate with my mother when I went abroad to study.
謝謝各位!
那請問before到底能用在哪里呢？句首應(yīng)該如何用呢？
抱歉又多問了個問題。。。
