11.Easter(复活节) is still a great day for worship,randy in baskets and running around the yard finding eggs,but every year it gets quite a bit worse for bunnies.
And no,not because the kids like to pull their ears.The culprit is climate change,and some researchers found that rising temperatures arc having harmful effects on at least five species of rabbit in the US.
Take the Lower Keys March rabbit,for instance.An endangered species that lives in the Lower Florida Keys,this species of cottontail is a great swimmer-it lives on the islands!-but it is already severely affected by development and now by rising levels.According to the Center for Biological Diversity,an ocean level rise of only 0.6meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat (栖息地) completely.
The snowshoe hare,on the other hand,has a color issue.Most of these rabbits change their fur color from white in the wintertime to brown in the summer,each designed to give them better cover from predators(捕食者).As the number of days with snow decreases all across the country,however,more and more bunnies arc being left in white fur during brown dirt days of both fall and spring,making them an easier mark for predators.Researchers know that the color change is controlled by the number of hours of sunlight,but whether the rabbit will be able to adapt quick enough to survive is a big question.The National Wildlife Federation has reported that hunters have noticed their numbers are already markedly down.
American pikas or rock rabbits,a relative of rabbits and hares,might be the firs'of these species to go extinct due to climate change.About 7-8inches long,pikas live high in the cool,damp mountains west of the Rocky Mountains.As global temperatures rise,they would naturally migrate (迁徙) to higher ground-but they already occupy the mountaintops.They can't go any higher.The National Wildlife Federation reports that they might not be able to stand the new temperatures as their habitat beats up.
The volcano rabbit has the same problem.These rabbits live on the slopes of volcanoes in Mexico,and recent studies have shown that the lower range of their habitat has already shifted upward about 700meters,but there are not suitable plants for them to move higher,so they are stuck in the middle.Scientists are concerned about their populations.
Native to the US,pygmy rabbits weigh less than 1pound and live in the American West.They are believed to be the smallest rabbits in the world.Their habitats have been destroyed by development.Several populations,such as the Columbia Basin pygmy,almost went extinct and were saved by zoo breeding programs.Pygmy rabbits also rely on winter cover by digging tunnels through the snow to escape predators,but lesser snowfall is leaving them exposed.
All of this gives new meaning to dressing up in a giant bunny costume this Easter.
28.The writer mentions Easter at the beginning of the passage in order toC.
A.show the importance of Easter Day
B.remind people of Easter traditions
C.introduce the issue about bunnies
D.discuss the relationship between Easter and bunnies
29.The word"culprit"( Paragraph 2)is closest in meaning toD.
A.producer         
B.judge          
C.victim      
D.criminal
30.Which best describes the writer's tone in the postage?A
A.Concerned.
B.Approving.
C.Enthusiastic.
D.Doubtful.

1.A child's place in the family birth order may play a role in the type of occupations that will interest him or her as an adult,new research suggests.In two related studies,researchers found that only children were more interested in intellectual,cognitive careers than later-born children.(51)C,later-born children were more interested in both artistic and outdoor-related careers.
"For example,parents may be extremely (52)B of only children and worry about their physical safety.That may be why only children are more likely to show interest in academic (53)A rather than physical or outdoor activities.An only child will tend to get more time and attention from their parents than children with siblings(兄弟姐妹).This will often make them feel special but the downside is that they may suffer from (54)B and loneliness when friends discuss their brothers and sisters and family life."
The first-born is an only child until the second child comes along-(55)D them from being the centre of attention,to then sharing the care of parents.Parents will also expect them to be responsible and"set an example".The change from being the focus of a family may be quite a (56)C and so shape the first-born's outlook on life.Therefore,first-borns may try to get back their parents'attention and approval by achieving success in their career.It is true that first-borns are (57 )B more often found as political leaders than any other birth-order position.
Being the youngest in the family can sometimes be a(n)(58)C experience,especially if the child wants to be taken seriously.The last-born is more likely than the other birth-order positions to take up dangerous sports.This may be a (59)D of the last-born's rebellious characteristic-a result of being (60)B up with always being bossed about by everyone else in the family.

3.W:Hi,Mr.Lee,I am (41)a reporter from the New York Times.It will be great(42)if you can tell me some information about chopsticks,(43)such as  their origin and the materials they are made from.
M:Good question.Chopsticks originated in China,but they are(44)widely (wide) used in many Asian countries.Chopsticks may be made of any of the (45)following(follow) materials:bamboo,wood,gold,silver,ivory,or plastic,and they may be(46)either either round or square.Some chopsticks are decorated (47)withcolored pictures.Ordinary chopsticks used in Chinese homes are made of wood or bamboo.In ancient times,the rich used jade or gold chopsticks to display their wealth.Many kings and emperors used silver chopsticks to see if their food had been poisoned.
W:OK,thank you.And I'd like to know why Chinese people use chopsticks.(48)Why not knives and forks,like Americans?
M:Oh,that is a good question.I think Chinese people choose chopsticks,rather than knives and forks,because Chinese people,under the influence of Confucianism,have traditionally (49)considered
(consider) knives and forks as symbolizing a type of violence.On the other hand,chopsticks reflect (50)gentleness(gentle) and kindness.And maybe Chinese food simply seems to taste better when eaten with chopsticks.
20.Across Britain,burnt toast will be served to mothers in bed this morning as older sons and daughters rush to deliver their supermarket bunches of flowers.But,according to a new study,we should be placing a higher value on motherhood all year.
  Mothers have long known that their home workload was just as heavy as paid work.Now,the new study has shown that if they were paid for their parental labors,they would earn as much as£172,000 a year.
  The study looked at the range of jobs mothers do,as well as the hours they are working,to determine the figure.This would make their yearly income£30,000 more than the Prime Minister earns.
  By analyzing the numbers,it found the average mother works 119 hours a week,40 of which would usually be paid at a standard rate and 79 hours as overtime.After questioning 1,000 mothers with children under 18,it found that,on most days,mums started their routine work at 7 am and finished at around 11 pm.
  To calculate just how much mothers would earn from that labour,it suggested some of the roles that mums could take on,including housekeeper,part-time lawyer,personal trainer and entertainer.Being a part-time lawyer,at£48,98 an hour,would prove to be the most profitable of the"mum jobs",with psychologist a close second.
  The study shows mothers matter all year long and not just on Mother's Day.The emotional,physical and mental energy mothers devote to their children can be never-ending,but children are also sources of great joy and happiness.Investing(投入) in time for parenting and raising relationsh ips is money well spent.
21.How much would a mother earn a year if working as the Prime Minister?D
A.£30,000.
B.£202,000.
C.£172,000.
D.£142,000.
22.What is stressed in the last paragraph?D
A.mothers'importance shows in family all year long.
B.Investing time in parenting would bring a financial return.
C.Mothers'devotion to children can hardly be calculated.
D.The sacrifices mothers make are huge but worthwhile.
23.What can we conclude from the study?B
A.Mothers'working hours should be largely reduced.
B.Mothers'labor is of a higher value than it is realized.
C.Mothers should balance their time for work and rest.
D.Mothers should be freed from housework for social life.
