Computers are a relatively new invention. The first computers were built fifty years ago and it is only in the last thirty or so years that their influence has affected our everyday life. Personal computers were introduced as recently as the early eighties.(前两句是什么意思?真没看懂) In this short time they have made a tremendous impact on our lives. We are now so dependent on computers that it is hard to imagine what things would be like today without them. You have only got to go into a bank when their main computer is broken to appreciate (这词在这什么意思?) the chaos that would occur if computers were suddenly removed world-wide.
It has been known for some time now that(啥意思) a move towards sources of energy which are not carbon-based is urgently required to stop the effects of global warming. In my view, there are too few governments who seem to be promoting (怎么用be doing 为什么? 直接to promote不行吗?) the use of other types of energy such as wind, wave, solar and nuclear sources of energy.
是雅思文章,从网上下的。谢谢老师
以上是前几句的意思
appreciate 应该是 “充分意识到,领会,体会”的意思
大概是说“你会深深地领会到没有电脑所带来的混乱”
It has been known for some time now that a move towards sources of energy which are not carbon-based is urgently required to stop the effects of global warming.
这句话中 It 是主语 “It has been known for some time now”已经是一个完整的句子 但是意思并不完整 因为主语太长了 所以用that引导放在后面了
be doing 的那个 因为前面他用的是“there are”所以要保持前后一致 就得用进行时
我不知道你用不用全文翻译一下 所以我没有翻译哦~~
