他把一生都投入到保护环境上去了．Hehas devoted all his lifetime to protecting the environment．题目和参考答案——青夏教育精英家教网—

8．他把一生都投入到保护环境上去了．
Hehas devoted all his lifetime to protecting the environment．

分析 has devoted all his lifetime to protecting the environment

解答答案：has devoted all his lifetime to protecting the environment．
首先分析句子的时态和结构，从汉语表述来分析，强调过去的动作对现在的影响，用现在完成时，现在完成时的构成是：主语+have/has+动词的过去分词；短语"把一生投入到…"用devote all one's lifetime to，该短语中的to是介词，后面跟动词的ing形式，短语"保护环境"是：protect the environment；主语为he，所以应用has，故答案为：He has devoted all his lifetime to protecting the environment．

点评此题考查对整句话的翻译，做这类题时先分析所给汉语句子意思确定相关的词汇和句型，然后仔细推敲时态考虑人称和数的变化等容易出错的问题．

3．Is the art of conversation dying？The other day，my wife 16A two teenage children did something we haven't 17C for ages．It didn't require the Internet，a TV screen，batteries…or anything else for that matter．But we all 18D it so much we're thinking of doing it again sometime．
We had a conversation．The kind of real，live conversation that was 19A when I was growing up，but which seems all too rare these days．Today we have chat rooms，text messages，e-mails but we seem to be losing the 20B of communicating face-to-face．We all know 21C young people are out on a date（约会）these days，they spend most of that time 22D their mobile phones．And teenagers nowadays seem to 23B communicating with their friends by sending text messages rather than actually 24C to them．
If we carry on like this，in the future，we'll lose the use of our 25B．What do you think？E-mail me，and who knows？Maybe we could even have a real conversation about it!
