2．Electric cars are dirty．In fact，not only are they dirty，but they might even be more dirty than their gasoline-powered cousins．
People in California love to talk about"zero-emissions （排放） vehicles"，but people in California seem to   be clueless about where electricity comes from．Power plants mostly use fire to make it．Apart from the few people who have their roofs covered with solar cells，we get our electricity from generators （发电机）．Generators are fueled by something----usually coal，oil，but also by heat generated in nuclear power plants．There are a few wind farms and geothermal （地热） plants as well，but by far we get electricity mainly by burning something．
In other words，those"zero-emissions"cars are likely coal-burning cars．Because the coal is burned somewhere else，it looks clean．It is not true．It's as if the California Greens are covering their eyes----"If I can't see it，it's not happening．"Gasoline is an extremely efficient way to power a vehicle； a gallon of gas has a lot of energy in it．But when you take that gas （or another fuel） and first use it to make electricity，you waste a nice part of that energy，mostly in the form of wasted heat--at the generator，through the transmission lines，etc．
A gallon of gas may drive your car 25miles．But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars burn more fuel than gasoline-powered ones．If our electricity came mostly from wind or geothermal，or solar，then an electric car truly would be clean．But for political，technical，and economic reasons，we don't use much of those energy sources．
In addition，electric cars'batteries which are poisonous for a long time will eventually end up in a landfill （垃圾填埋场）．And finally，when cars are the polluters，the pollution is spread across all the roads．When it's a power plant，though，all the junk is in one place．Nature is very good at cleaning up when things are not too concentrated，but it takes a lot longer when all the garbage is in one spot．

29．Which of the following words can replace"be clueless about"in Paragraph 2？A
A．fail to understand． B．be familiar with．
C．be curious about．    D．show their interest in．
30．The electricity we get from a gallon of gas may make our car runB．
A．at least 25miles      B．less than 25miles
C．more than 25miles     D．as far as 25miles
31．In the author's opinion，compared with cars using gas，electric cars are moreC．
A．efficient             B．expensive
C．harmful               D．environmentally-friendly
32．It can be inferred from the passage thatD．
A．electric cars'batteries are no longer poisonous in the landfill
B．now electric cars are used more than their gasoline-powered cousins
C．zero-emissions vehicles should be chosen to protect our environment
D．electric cars are not clean since we get electricity mainly by burning something．

12．Long ago the Emperor decided to hold a swimming race between 13different animals．The order in which they finished would decide the order of their （61）appearance （appear） in the Chinese calendar．All the animals lined up on the river bank and （62）were given （give）the task of getting to the opposite shore．The cat wondered how he would get across（63）because/as he was afraid of water．The ox worried how he would cross （64）with his poor eyesight．The calculating rat suggested that he and the cat （65）jump （jump） onto the ox's back and guide him across．The ox，steady and hard-working，did not notice the two animals on his back．In the meanwhile，the rat ran behind the unsuspecting cat and pushed （66）him into the water．As the ox came ashore，the rat jumped off and finished the race first．．（67）So/Thus the rat got the first year （68）named （name） after him and the ox got the second year．（69）When the lazy pig reached the finish line in 12th place，the race was over and he was awarded the final place on the calendar．From that day the cat，（70）who never finished and lost his place on the calendar，became the enemy of the rat．

19．Sea turtles come in many different sizes，shapes and colors．The shell of each sea turtle species is different in length，color，shape and the arrangement of the scales（鳞片）．
Sea turtles do not have teeth but use their jaws （下巴）to eat．Their sense of smell is excellent．Th eir eyesight underwater is good，but they have near-sighted eyes out of water．Their special bodies make them adapt to life at sea．However，sea turtles maintain（保持） close ties to land．
Female sea turtles have to go to the seaside to lay their eggs in the sand； therefore，all baby sea turtles begin their lives on land．Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest，largely because they ca n be found most easily．After decades of studying sea turtles，much has been learned about．However，many mysteries（谜） still remain．
Researchers do not yet know how long baby turtles spend in the open sea，or exactly where they go．People believe they spend their earliest years floating in the sea，where they do little more than eat and grow．Once turtles reach dinner-plate size，they appear at feeding grounds in waters near the shore．They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles，depending on the species．There is no way to know the age of a sea turtle from its physical appearance．It is believed that some species can live for over 100 years．
