10．Mountain lions live in mountainous areas of the western United States．Lately，however，people have reported seeing them in quiet neighborhoods all across the country!Usually considered shy and seldom seen，these lions are becoming more noticeable．In addition，the lions appear to be moving east．They were even reported in the suburbs of Boston，Philadelphia，and Chicago．
It seems certain that these"kings of the mountains"are moving．Why？Scientists are not sure．Some think that as the mountain lion population increases in the west，younger wild cats are leaving the area．These cats are searching for new homes and new places for food．
"The young males are looking for new homes，"says Lynn Sadler，who is the director of the Mountain Lion Foundation in Sacramento，Calif．"People tend to create too many barriers，such as buildings，fences，roads，and noise．As the mountain lions seek new places and food and water sources，these barriers get in their way．"
The sightings have made people increasingly watchful．Sometimes the"mountain lions"that people report seeing turn out to be large dogs or even house cats．But at least a few of the meetings have been real．The building of new roads，t he growing of suburbs and the growing popularity of outdoo r activities are all increasing the chances that people in various parts of the country may meet up with a mountain lion．
Because many people are concerned about the reappearance of the American lion，an expert outlined some ways they can avoid attracting the wild cats：Never leave pets or pet food outside； properly care for farm animals； and plan public land use to enable the lions to move safely from one place to another．
"To be fair，"says the expert，"mountain lions are trying to regain their homes．They were here first．Now we need to find ways we can live together．"
28．Mountain lions are moving probably becauseC．
A．the suburbs of big cities are peaceful and quiet
B．more roads are being built into the mountains
C．the number of the lions increases in the west
D．young lions are seeking new partners
29 According to the passage，it is clear thatB．
A．the reported sightings of mountain lions have not been proved
B．people walking in the country may come across a lion
C．fences have been built to protect the lions
D．mountain lions prefer populated areas
30．To avoid attracting mountain lions，people are advisedB．
A．to build more roads for the lions to move safely
B．to keep a close watch on their farm animals
C．not to stay outdoors
D．not to raise pets
31．Which is the best title for the passage？A
A．Mountain Lions in Unlikely Places
B．Measures Taken to Avoid Lions
C．Number of Sightings Going Up
D．Mountain Lions Moving West、

分析 本文是一篇議論文．文章主要講述了美國的山獅目前生存的范圍越來越廣的原因，文章也介紹了人們應該如何應對美國的山獅．

解答 28．C  細節(jié)理解題．由文章第二段"Some think that as the mountain lion population increases in the west，younger wild cats are leaving the area．"可知它們遷徙是因為數(shù)量增加，故選C．
29．B 細節(jié)理解題．細節(jié)理解題．第四段最后一句話"the growing of suburbs and the growing popularity of outdoor activities are all increasing the chances that people in various parts of the country may meet up with a mountain lion．"知人們在穿越森林的時候可能遇見獅子，B項是正確的．
30．B 細節(jié)理解題．由第五段Because many people are concerned about the reappearance of the American lion，an expert outlined some ways they can avoid attracting the wild cats：Never leave pets or pet food outside； properly care for farm animals； and plan public land use to enable the lions to move safely from one place to another．可知人們要密切關(guān)注家養(yǎng)的動物，故B正確．
31．A 主旨大意題．文章開始說原本應生活在山中的美洲獅會時常出現(xiàn)在一些城市的郊區(qū)，第二段探討過美洲獅來到這些unlikely places的原因，下文又接著告訴人們應如何對待或避免遇到獅子等．故A正確．D項錯在moving west．

點評 做閱讀時經(jīng)常犯錯的主要原因是，僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案，這樣便很容易掉入出題人故意設(shè)布下的題目陷阱．所謂閱讀理解，對于題目的理解一定要忠實于原文，因此，每一道題都應該與原文作全面的對比與核查，再得出答案．也就是說，閱讀理解的每一道題目，在原文都應該有明確的出處，我們把這一出處叫做原文相關(guān)句，（1）排除與原文相關(guān)句主題不一致的選項（2）排除與原文相關(guān)句態(tài)度相反的選項 （3）排除用于過于極端或負面的選項（4）注意結(jié)合文章主旨和主題去排除．

20．Women turn to online shopping
Women have jumped ahead of men for the first time in using the Internet to do their holiday shopping，according to a study published last week in the US．
For Years men have been more likely to shop on the Internet than women，but during the 2014holiday season，58percent of those making online purchases were women．
"It shows how mainstream the Internet is becoming"，said Lee Rainie，director of the Pew Internet and American Life Project Group，which carried out the study．
Rainie said it was only a matter of time before women shoppers caught up with men．This is because women traditionally make decisions about spending．

"But even if shoppers don't buy online，websites are becoming promotion tools for stores，"said Dan Hess，vice president of Comscore Networks Inc．Hess said that actually most stores'websites can make customers fully believe the security of their credit card numbers．And most are able to ensure that gifts arrive on time．
"It's all about making the shopping experience more efficient，more reliable and more comfortable，"Hess said．
24．What can we know from the passage？D
A．People，except young，don't like to do gift-shopping online
B．American people only buy gifts in holidays．
C．Shopping off-line provides better service．
D  People like to do gift-shopping online．

1．Burdens（負擔） Give Us Wings
The legend tells us that unlike other animals，the birds volunteered to help God carry the burdens to the destination happily．（61）Unexpectedly （expected），wings replaced the loads afterwards，which enabled the birds to fly．
It's true that everyone，willingly or unwillingly，carries burdens of this or that kind，and I am （62）no exception．I am burdened with （63）endless （end） homework，unsatisfactory performance，and disagreements（64）withmy family sometimes．But（65）as/because/sinceI always focus on the sunny side of life，I see these burdens as opportunities （66）to learn（learn） more knowledge，gain more experience and thus grow more and more mature（成熟的）．
（67）Taking（take） advantage of the burdens properly，we can turn them into wings that help us fly closer and closer to our goals．For one thing，we should treat various burdens differently．Take those worth （68）struggling（struggle） for seriously and let go of the unimportant and unnecessary．For another，once we decide on a worthwhile goal，we should keep the （69）faith（faithfully） that as long as we shoulder any loads with a light heart，we will make（70）iteventually．
Burdens give us wings．

5．Forty years ago，F(xiàn)inland was a small country with mediocre（普通）public schools．Today，F(xiàn)inland is still small but no one calls Finland's public schools mediocre any more．
In 2000，the Finns surprised the world when their 15-year-olds scored at the top of a closely watched international exam called the PISA．Finland has stayed near the top ever since，while the U．S．scores around the middle．
Pasi Sahlber g，an official with Finland's Ministry of Education and Culture，is in Seattle this week to share the story of Finland's success，and what states like Washington can learn from it．
Sahlberg's message，although he is too polite to put it so bluntly（坦率）：Stop testing so much，trust teachers more； give less homework； shorten the school day．
On Tuesday，in a room filled with teachers，principals，professors，school-board members and policy makers，Sahlberg joked about the Finns'reputation（名聲） for being a quiet，humble people．"When Finland hit the top of the PISA，"he said，"the biggest disbelievers were Finns．"
More seriously，F(xiàn)inland never set out to create the world's top school system．Instead，he said，the country deci ded in the 1970s that it wanted to ensure that a student's success didn't depend on family background．
"Finland relied on cooperation among teachers and schools，rather than on competition．Rather than judging teachers and schools based on test scores，"he said，"Finland puts trust in its teachers and principals．Teachers develop the curriculum in Finland，and design their own tests．There are no nat ional tests，except one at the end of high school．"
That's just the start．Along with a shorter school day，F(xiàn)innish students don't even start school until they are 7 years old．Many primary schools have a policy against giving homework．
"But Finland，"he said，"succeeded in part by adopting ideas from the U．S．a(chǎn)nd other countries．And those countries，"he said，"can learn from Finland，too．"

32．What might be the author's purpose of writing the passage？C
A．To introduce a Finnish official．
B．To compare the education systems of Finland and the US．
C．To share the story of Finland's success in education．
D．To ask the US to improve its education．
33．People first learned Finland's success in education fromA．
A．its students'performance in an international exam．
B．its international exchange programs．
C．lectures given by Pasi Sahlberg．
D．its small-sized public schools．
34．Which of the following can contribute to Finland's  success in education？C
a．Giving students fewer tests．
b．Giving teachers more trust．
c．Evaluating students'family backgrounds．
d．Creating the world's top school system．
e．Starting school late．
A．a(chǎn)，b，c              B．c，d，e          C．a(chǎn)，b，e           D．b，c，d
35．What Pasi Sahlerg said in Paragraph 7 suggested thatB
A．children should start school as early as possible．
B．competition among teachers might be harmful to education．
C．the US education system is still the most advanced．
D．it is necessary to set up a national curriculum．

19．In a little-known part of the counter-terrorism （反恐怖主義） world，one of the most effective detection systems is a 600-pound animal that works for about 20pounds of fish a day．
Since the 1960s，the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers，and to recover worn--out torpedoes （魚雷） and testing objects used in naval （海軍的） exercises．
The U．S．Navy kept its Marine Mammal Program a secret until the 1990s，and this spring CNN became one of the first members of the media to witness firsthand how the program works．
The program trains about 75Pacific bottlenose dolphins，with natural biosonar （生物聲納） that tracks better than any manmade device； and 35California sea lions，with very good underwater eyesight．
Not only do these trained marine mammals track and save millions of dollars in U．S．military equipment，they are also helping to save lives．The Navy won't reveal whether the dolphins and sea lions have effectively stopped terrorists attempting to do harm to the U．S．
A key part of the training program is teaching these mammals how to stop potentially unfriendly swimmers．The program is also positioned to defend against swimmer terrorist attacks as well．
In the digital age，it seems that there should be more advanced approaches to guard the Navy's most expensive things．But according to Rothe，the program director，nothing in today's high-technology world can compete with these mammals'biosonar abilities．"I hope that one day there is a robot or a UUV （un-manned underwater vehicle） that makes the mammal program out of date，"he said．"But right now this is the best thing out there．"
25．The U．S．Marine Mammal Program trained marine mammals toA．
A．stop dangerous swimmers
B．catch 20pounds of fish a day
C．destroy sea mines
D．fire torpedoes
26．What can we learn from the last paragraph？A
A．The trained dolphins are the best way of protection available to the U．S．Navy．
B．There will be dolphin-like robots in the future according to Rothe．
C．The mammal program will become useless soon．
D．Rothe has no faith in today's high technology．
27．Which of the following is TRUE according to the text？D
A．Many countries have trained sea animals for counter-terrorism．
B．The Marine Mammal Program was a secret until the 1960s．
C．The trained sea animals have already stopped some terrorists．
D．The U．S．Navy has trained both dolphins and sea lions．
