Question

2．In the modern age，human society runs on energy．Most machines need electricity to operate．Humans can not live without electricity even a single day both in their daily life and work．They have many different ways to create electricity．But some ways are harmful to the environment．
For example，fossil fuels（化石燃料）are the most common kind of energy．They include coal，oil，and nutural gas．First，people have to dig them from the groud．This can sometimes harm the environment．However，scientists are creating cleaner and better ways to do that these days．So the environment is not harmed as much as before．But when people burn these fossil fuels，they can give off a lot of harmful gases，which is considered to be one of the greatest causes of global warming．This might harm the environment．
Tidal（潮汐）energy is another way to make electricity．This uses the ocean tides to make electricity．But some kinds of tidal energy can kill many fish and other sea animals．Also dams（大坝）can create lots of clean energy．But dams create lakes and change the way that rivers tun．So they can do great harm to the balance of nature around the lakes and along the rivers．

34．According to the passage，which of the following is TRUE about fossil fuels？
A．They are dug from the groud．
B．They are considered expensive．
C．They hardly harm the environment．
D．They are not widely used in the world．
35．From the passage，we know that tidal energy canD．
A．cause serious accidents                
B．change the way that rivers run   
C．give off a lot of harmful gases        
D．kill many living things in the ocean
36．Nowadays many countries start to use nuclear energy more becauseC．

A．health         
B．science

D．sports．

Answer 1

分析 在现代社会，社会的发展需要能源．但是有些能源的使用给我们的环境造成了危害，比如化石燃料和潮汐能．

解答 34．A 细节理解题  根据"First，people have to dig them from the groud"可知，化石能源是由地下开采出来的，故A选项正确；文中并没有提到化石燃料的价格问题，故B选项不正确；根据"This can sometimes harm the environment"可知，化石燃料会危害环境，故C选项不正确；根据"fossil fuels（化石燃料）are the most common kind of energy"可知，化石燃料使用较广泛，故D选项不正确．答案为A
35．D  细节理解题  文中并没有提到潮汐能可以导致严重的事故，故A选项不正确；根据"But dams create lakes and change the way that rivers run"可知，大坝可以改变河流的流向，故B选项不正确；文中并没有提到潮汐能可以产生有害气体，故C选项不正确；根据"But some kinds of tidal energy can kill many fish and other sea animals．"可知，潮汐能可以杀死海洋里的生物，故D选项正确．答案为D
36．C  推理判断题  根据"However，scientists are creating cleaner and better ways to do that these days．So the environment is not harmed as much as before"可知，人们使用新能源是为了更清洁、更安全，故答案为C
37．B  推理判断题  根据短文大意可知，文中在介绍能源的使用及与环境相关的知识．故这篇文章应该出现在报纸上的科学部分．
