Ⅴ.单元词汇整合——背诵下面短文(黑色字体为本单元必备词汇) The mobile phones and the Internet have brought us a lot of benefits, such as online shopping, information searching, keeping track of events, chatting and so on. However, many people are buried in the phone, and completely cut off from the outside world. As is often the case, adults are busy with their own business, with their children watching cartoons or playing children's games online. They click on the buttons, laughing and screaming even with rude words streaming out according to their own performance, which seems familiar to me. Targeted at children, the games are frequently updated. Long­time Internet use is harmful to children's health and eyes. Children who wear glasses because of near­sightedness tend to be younger and younger. Strict regulations must be made to protect children. First, children's games are prohibited to go online. Second, parents should be pressed to change their false attitudes towards children's education. I sincerely hope a solid foundation can be laid for the future development of children. ★本单元我学到了哪些语法规则？ _________________________________ _________________________________ ★本单元我学到了什么写作手法？ __________________________________ __________________________________ $
