16．Read the passage and fill in the blanks with proper words（在短文的空格内填入适当的词，使内容通顺，没空格限填一词）
We are now living in the modern city．Most of the energy which we are using for heating lighting，transportation and manufacturing（工业生产） is from fossil fuels（化石燃料）．These are carbon-based（碳基燃料） fuels from oils，coal and natural gas．When we burn these fuels we release（释放） heat which （81）provides the energy．
There are three major disadvantages to using these fuel．Firstly，they are causing climate problems because fo the （82）greenhouseeffect．When we burn fossil fuels they produce carbon dioxide （二氧化碳）which causes global warming．Secondly，when we have used up all our coal，oil and natural gas，we will have （83）nothingleft to burn．Thirdly，they are not very efficient．The internal combustion engine that we use in most cars，trucks and buses，for example，is only about 14% efficient．
Scientists are working on an alternative（替代的）fuel--hydrogen（氢）．There are a number of advantages to using hydrogen as a fuel．Firstly，because two thirds of the （84）earth's surface is water and water is made of hydrogen and oxygen（氧）．There is an almost unlimited（无限的）supply of hydrogen．Secondly，burning hydrogen does not cause global warming．Thirdly it is much more efficient than carbon-based fuels．
Unfortunately there are problems with hydrogen at the present time：there is the problem of separating it from water （85）cheaply，if it is too expensive，we can not afford to use it；and there is the difficulty of storing it．It can be stored under pressure but high pressure tanks are far from sage．It can also be stored as a liquid but only at extremely（非常）low temperatures．It seems likely，therefore，that there will have to be completely new technologies before hydrogen replaces fossil fuels．（86）Solving these problems is an urgent matter．Although China，India and Australia have huge quantities（大量）of cheap coal，and there are still （87）large oil and gas reserves（储备）elsewhere，the effects on the planet's climate will be catastrophic（灾难性的）if they are used．
