Start a conversation with 你这里说的是conversation吗?我怎么听得是另一个词呢。然后手机那块你说everyone has a cellphone and do not stay without them. 有两个问题, 一个主语是everyone的话,那后边用 does not. 第二点 感觉有点中式英语,do not stay without them? 不如说people live without cellphone,they bring cellphone with them all the time, which makes it easier for me to contact them.
