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（大壩）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．it's a common kind of energy   
B．people ara not afraid of it now   
C．it's cheap，clean and safer than before   
D．people can't live without nuclear energy
37．The passage is probably in the part ofBin a newspaper．
A．health         
B．science        
C．culture         
D．sports．

Answer 1

分析 在現(xiàn)代社會(huì)，社會(huì)的發(fā)展需要能源．但是有些能源的使用給我們的環(huán)境造成了危害，比如化石燃料和潮汐能．

解答 34．A 細(xì)節(jié)理解題  根據(jù)"First，people have to dig them from the groud"可知，化石能源是由地下開(kāi)采出來(lái)的，故A選項(xiàng)正確；文中并沒(méi)有提到化石燃料的價(jià)格問(wèn)題，故B選項(xiàng)不正確；根據(jù)"This can sometimes harm the environment"可知，化石燃料會(huì)危害環(huán)境，故C選項(xiàng)不正確；根據(jù)"fossil fuels（化石燃料）are the most common kind of energy"可知，化石燃料使用較廣泛，故D選項(xiàng)不正確．答案為A
35．D  細(xì)節(jié)理解題  文中并沒(méi)有提到潮汐能可以導(dǎo)致嚴(yán)重的事故，故A選項(xiàng)不正確；根據(jù)"But dams create lakes and change the way that rivers run"可知，大壩可以改變河流的流向，故B選項(xiàng)不正確；文中并沒(méi)有提到潮汐能可以產(chǎn)生有害氣體，故C選項(xiàng)不正確；根據(jù)"But some kinds of tidal energy can kill many fish and other sea animals．"可知，潮汐能可以殺死海洋里的生物，故D選項(xiàng)正確．答案為D
36．C  推理判斷題  根據(jù)"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，人們使用新能源是為了更清潔、更安全，故答案為C
37．B  推理判斷題  根據(jù)短文大意可知，文中在介紹能源的使用及與環(huán)境相關(guān)的知識(shí)．故這篇文章應(yīng)該出現(xiàn)在報(bào)紙上的科學(xué)部分．

點(diǎn)評(píng) 做這道題時(shí)要先通讀全文，弄清短文大意，然后根據(jù)相關(guān)句子選出正確答案，最后仔細(xì)檢查．
