D 

             Scientists have long known that turtles,like many animals,find their way and direction at sea by sensing the invisible(無(wú)形的) lines of Earth's magnetic field(磁場(chǎng)) similar to how sailors use latitude(緯度)and longitude. But they didn,t know

how turtles were able to return to the very spot where they were born.

              Now a study has the answer: Turtles also rely on Earths magnetic field to find their way home. That's because each part of the coastline has its own magnetic signature,which the animals remember and later use as an internal compass. It's not an easy way,though — the magnetic field turns slowly,and turtles have to change their nesting sites in response's pretty amazing how these creatures can find their way through this vast expanse of nothing/' said study co-author J. Roger Brothers.

              Turtles have a great range that surrounds all but the coldest waters of the world's oceans. Though they travel hundreds of miles out to sea,turtles seem to prefer coastal areas.

              Every year,thousands of volunteers walk along Florida's sandy beaches to count turtle's nesting sites,which provides scientists with a rich population data set. At the same time,researchers have been studying slight changes in Earth,s magnetic field along Florida's coasts to measure how the fields strength and other characters change over time. Brothers and his colleagues combined the citizen-science data on turtle nests and official data about the magnetic field to find how everything changed over time.

              Nathan Putman,a biologist with the National Oceanic and Atmospheric Administration's Southeast Fisheries Science Center,added,“It,s really creative work,the type that makes you think, ‘Why didn’11 think of that?’ ”

              The results could also influence conservation ways for these endangered animals,said Brothers. The population of the animals has fallen due to pollution,and development in their nesting areas. Many conservationists surround turtles' nests with wire cages. Since these cages are usually metallic,the practice could affect the turtles,ability to find their way home.

32. Why does the author say “It's not an easy way”?

   A. Turtles always travel far away from home.

   B. Earth's magnetic field changes constantly.

   C. It's hard for turtles to feel the invisible lines.

   D. It takes turtles too much time to plan their route.

33. What is the main idea of Paragraph 4 ?

   A. How the data was collected.

   B. How important the research was.

   C. How the research was carried out.

   D. How meaningful the data is in modem life.

34. What does Nathan Putman think of the findings of Brothers and his team?

   A. There is still a long way to go.

   B. Their efforts are worthwhile and inspiring.

   C. They are the most important findings on turtles.

   D. The results may cause doubts from other scientists.

35. According to the last paragraph,why are some cages put around turtles’ nests?

   A. To expand their nesting areas.

   B. To help them rest comfortably.

   C. To guide them to their home.

   D. To prevent them from leaving.

本文是說(shuō)明文。文章主要介紹了海龜可以跟蹤地球的磁場(chǎng)來(lái)準(zhǔn)確找到它們的家。

32. B. 細(xì)節(jié)理解題。由第二段中的打、 not an easy way,though — the magnetic field turns slowly,and turtles have to change their nesting sites in response 可知,地球磁場(chǎng)是變化的,海龜需要不斷地調(diào)整來(lái)適應(yīng)。

                                      C 

                      

              Contestants from around the world met in Pomona, California,this month to test their skills at things like driving a car,walking down stairs,and opening doors. Sounds easy,right? But the competitors weren't people — they were robots!

              The bots were participating in  the final round of the US,s DARPA (Defense Advanced Research Projects Agency) Robotics Challenge. This event,which took place on June 5-6,tested robots on how well they could respond during a disaster and the winning team finally took home a $2 million grand prize.

              The DARPA challenge was created after the 2011 Fukushima nuclear disaster in Japan. An earthquake caused a tsunami,which damaged a nuclear power plant. Workers at the plant needed to shut bff an important valve(閥門(mén)) ,but it was too dangerous for humans to reach it. The US scientists at DARPA wondered whether the disaster could have been avoided if a robot had been sent to do the job. So they set up the robotics competition.

              Turning a valve was just one task a robot might have to perform when entering a disaster zone. In addition to doing this,robots participating in the challenge had to navigate a course containing several other tasks: driving and exiting a vehicle, opening a door,walking over or clearing objects,cutting a hole in a wall,plus climbing a flight of stairs.

               Teams had to complete the challenge in one hour,and points were awarded based on how quickly the robots completed a task. They didn't have to attempt all the tasks. To make things even more realistic,challenge organizers caused short computer-system blackouts(斷電) that prevented robots and the human operators controlling them from communicating. That means teams had to program their bots to be partially autonomous (獨(dú)立的) . Robots also couldn’t be attached to anything that could keep them from falling down , which happened a lot.

29.What do we know about this year's DARPA challenge?

   A. It lasted five days.

   B. It was held in Japan.

   C. Its winner got a cash prize.

   D. Its winner will work in Fukushima.

30.What does the underlined part “the job” in Paragraph 3 refer to?

   A. To open a door.

   B. To close a valve.

   C. To predict a tsunami.

   D. To rebuild a nuclear power plant.

31.The robots that participated in the US,s DARPA challenge were required to .

   A. challenge all the tasks

   B. have a good sense of smell

   C. complete their tasks in an hour

   D. act in the dark in the whole process

32.What is the text mainly about?

   A. A nuclear disaster.

   B. A research program.

   C. A robotics competition.

   D. A scientific organization.

                                     C 

               President Barack Obama renamed North America,s tallest mountain this week. For almost 100 years,the 20,310-foot Alaskan peak has been identified on most maps as Mount McKinley. Its name is now officially Denali.

               This “new” official name isn't really new at all. Obama changed the mountain's name to Denali because,for generations,that's what people in Alaska have called it. The Athabascan people,a Native Alaskan group,named the peak Denali long ago. It means “high one” or “great one."

               “We are officially renaming the mountain Denali in recognition of the traditions of Alaska Natives and the strong support of the people of Alaska,” said U.S. Interior Secretary Sally Jewell. Alaska Senator Lisa Murkowski praised Obama's move. “I'd like to thank the president for working with us to achieve this significant change to show honor,respect,and gratitude to the Athabascan people of Alaska,she said.

                The name Mount McKinley got its start in 1896. At that time,there was a gold rush going on in Alaska. A gold prospector(勘探者) wanted to honor William McKinley of Ohio,who had just been nominated(提名) to run for U.S. president.McKinley would go on to become the nation's 25 th president. He was killed in 1901,six months into his second term as president. The U.S. Congress made the name Mount McKinley official in 1917.

                Native Alaskans were insulted(侮辱) by the name change. The result has been a political tug-of-war between Alaska and Ohio. Since 1975,Alaska politicians have pushed Congress to change the name back to Denali. Now that President Obama has changed the name,some people in Ohio are very unhappy. “This political change is insulting to all Ohioans” said Congressman Bob Gibbs,who is from that state.

               Denali also made news this week for another reason: U.S. officials decreased its official height by 10 feet. The United States Geological Survey announced that Denali is 20 ,310 feet high,not 20,320 as previously thought. The mountain has not shrunk (萎縮) . Advances in technology allowed scientists to take more accurate measurements of it.

29. Why has the U.S. government renamed its tallest mountain?

   A. To end a long political debate.

   B. To show respect for Alaska Natives.

   C. To remember the nation's 25 th president.

   D. To officially identify the mountain's name on maps.

30. What's Ohioans’ attitude towards the new name of Mount McKinley?

   A. Excited. B. Amazed.

   C. Puzzled. D. Disappointed.

31. What do we know about Mount Denali?

   A. It is actually 20 ,310 feet in height.

   B. It was found by a gold prospector.

   C. It was originally named McKinley.

   A. It isn’t North America's tallest mountain.

32. What would be the best title for the text?

   A. A political tug-of-war

   B. From McKinley to Dendi

   C. The tallest mountain found

   D. In honor of William McKinley
