8．Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment．Animals become endangered for a variety of reasons．
Some animals become endangered when their habitats contain resources for humans．For example，commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups．Land itself is an important resource to humans since it provides us with living space，and when people replace animal habitats with human habitats，it can lead to larger loss of natural species．
Commercial and industrial operations may reduce land or water for animals and pollute their environment．Due to water pollution，the baiji，a fresh water dolphin native to China，was declared extinct，meaning it's unlikely the population can recover．Even noise pollution from human activities can lead to the disorder of animal behavior．
Another cause that makes animals become endangered is over-fishing or over-hunting．Over-hunting whales led to near extinction of many species of whales．
The introduction of a non-native species to a habitat may make animals become endangered．The native species may not defend against a new one，and the effects can be dangerous．In Australia，the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals．
Introduced species can also bring new diseases with them．As a result，animals become endangered．Native animals may not have the power to fight against non-native diseases，and population levels can suffer．Another cause of disease is human-introduced chemicals．The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction．
When animals become endangered，the entire food chain can be affected．For example，in 2008 disease seriously harmed the honeybee，which is largely responsible for pollinating（授花粉）  plants，including many fruits and vegetables．Without their pollination，a very large part of the human diet could be reduced．In fact，if the honeybee should become extinct，our life would be affected and billions of dollars would be lost．Therefore，many people argue that when animals become endangered it is in man's own self-interest to protect them．

61．The passage is mainly aboutD．
A．ways of protecting animals'habitats
B．effects caused by species endangerment
C．dangers of bringing in non-native species
D．reasons why animals become endangered
62．Which of the following examples shows that environmental pollution may cause species endangerment？B

A．Native species are likely to die from the new diseases．
B．It's hard for non-native species to survive．
C．Non-native species will take up more space．
D．Native species are so powerful for non-native species．
64．The California Condor is in danger of dying out because ofB．
A．loss of habitat                                                       
B．harmful chemicals
C．forest cutting

15．If you see a group of people dancing and singing on the street or in the railway station，you don't need to feel surprised．They are a flash mob （快闪族），which is a group of people who come together suddenly in a public place，do something unusual for a brief period of time，and then quickly break up．They are usually organized with the help of the Internet or other digital communication network．At a predetermined time，they gather and perform some  distractions（消遣）such as waving their hands and exchanging books．Then，they quickly break up before the police can arrive．Using mobile phones，the flash mob can change its location if the first one has been replaced for any reason．
Bill Lasik，senior editor of Harper's Magazine，organized the first flash mob in Manhattan in May 2003and the first successful flash mob came together on June 3，2003-after the first attempt was   foiled at Macy's department store．Lasik claimed that the activity was designed to make fun of hipsters （起时髦的人），and call attention to the cultural atmosphere．
Flash mob gatherings can sometimes shock people．Such an activity might seem amusing and untrue，but it also might frighten people who are not aware of what is taking place．Undoubtedly，flash mobs can serve as good political tools in any direction．They also have great economic potential，such as using flash mobs to advertise a product．
The flash mob is now becoming more and more popular．People use it to do many things．For example，in 2009，Michael Jackson's fans took part in a flash mob to remember him．Hundreds of his fans gathered singing and dancing Michael's famous song"Beat It"together．Flash mobs give people from all walks of life an opportunity to come together to create a memory．

21．The underlined word"foiled"in Paragraph 2can be replaced by _B．
A．forgotten         B．prevented        C．announced         D．confirmed
22．What can you learn about the flash mob from the passage？D
A．The flash mob usually breaks up quickly for lacking enough time．
B．Once the place for the activity is determined，it can't be changed．
C．The flash mob can be made use of in many fields just for fun．
D．It gives people the chance to come together to do something unusual．
23．The main purpose of the passage isC．
A．to entertain       B．to encourage       C．to inform       D．to persuade
24．The writer's attitude towards the flash mob isB．
A．negative        B．objective         C．favorable        D．doubtful．
5．From a very early age，some children exhibit better
self-control than others．Now，a new study that began with about 1，000 children in New Zealand has tracked how a child's low self-control can predict poor health，money troubles and even a criminal record in their adult years．
Researchers have been studying this group of children for decades now．They observed the level of self-control the youngsters displayed．Parents，teachers，even the kids themselves，scored the youngsters on measures like"acting before thinking"and"Persistence in reaching goals．"
The study led  by Moffitt of Duke University and colleagues followed 1，000 children from birth to age 32 in Dunedin，New Zealand．
"The children who had the lowest self-control when they were age three to ten，later on had the most health problems in their 30s，"Moffitt said，"and they had the worst financial situation．They were more likely to have a criminal record and to be raising a child as a single parent on a very low income．"Moffitt explained that self-control problems were widely observed，and weren't just a feature of a small group of misbehaving kids．
Moffitt said it's still unclear why some children have better self-control than others，though she said other researchers have found that it's mostly a learned behavior，with relatively little genetic influence．But good self-control can be set to run in familles because children with good self-control are more likely to grow up to be healthy and prosperous parents．But the good news，Moffitt said，is that self-control can be taught by parents，and through school curricula that have been shown to be effective．
61．From the first two paragraphs we learn that．B
 A．the research has been carried out for five years
 B．self-control in kids tends to determine their future
 C．self-control was assessed by children's intelligence
 D．children's self-control is almost the same at early age
62．Children with low self-control are more likely to．D

B．get good school performance
 C．have better financial planning  
D．adopt negative behaviors
63．According to Moffitt，．D
 A．only good genetic factors can shape their lives in the future
 B．scientists know well why some children have better self-control
 C．self-control in childhood has nothing to do with criminal activity
 D．willpower as a child really influences people's chances of adulthood
64．What can be inferred from the passage？D
 A．Self-control cannot be taught in schools．
 B．The study is restricted within few participants．
 C．It's never too late to deal with self-control problems．
 D．Good parenting can improve self-control and life success．
65．Which of the following might be the best title of the  passage？A
 A．Child's self control predicts future health，success
 B．Kids are encouraged to take risks at an early age
 C．Children's development cannot be changed by teachers

12．During the first half of the nineteenth century in the United States，Christmas was a very different kind of holiday than it is today．There was no set of way of celebrating the day，which was not yet an official holiday．（71）GSome observed Christmas as an important Christian religious day honoring the birth of Jesus．Others celebrated the day with parties，music，drinking and eating．（72）C
（73）FCalvinist Christians banned the celebration of Christmas．But groups such as Episcopalians and Moravians honored the day with religious services and seasonal decorations．
By mid-century，Christian groups began to ignore their religious diffrences over the meaning of Christmas and honored the day in special ways．
Christmas became an important time for families to celebrate at home．More and more Christians Americans also began to follow the European traditions of Christmas trees and giving gifts．Christians believed that the tree represented Jesus and was also a sign of new beginnings．German immigrants brought their tradion of putting lights，sweets and toys on the branches of evergreen trees placed in their homes．
This tradition of setting up a Christmas tree soon spread to many American homes．（74）A As these traditions increased in popularity，the modern trade and business linked to Christmas also grew．
As Christmas became more popular，some states declared the day a state holiday．Louisiana was the first state to make the move in eighteen thirty-seven．（75）B．It was not until eighteen seventy that President Ulysses Grant made Christmas a federal holiday．

A．So did the practice of giving people presents．
B．By eighteen sixty，fourteen other states had followed．
C．And，some communities did not celebrate the day at all．
D．Americans seldom gave each other presents on Christmas Day．
E．But many new American Christmas songs started to become popular．
F．Religion played a big role in how an American might celebrate the holiday．
G．Communities around the country honored the day in different ways．
9．It is a general rule that all types of activity result in boredom when they are performed on （61）a routine basis．Actually，we can see this principle at work in people of all （62）ages（age）．For example，on Christmas morning，children are excited （63）about playing with their new toys．But their interest soon dies down and by January （64）it is those same toys that can （65）be found（find） put away in the basement．The world is full of half-filled stamp albums and unfinished models，each （66）standing（stand） as a monument to someone's passing interest．Adolescents enter high school with great （67）excitement（excite） but are soon looking forward to graduation．And then，how many adults，（68）who now complain about the long drives to work，eagerly drove for hours at a time when they first got their driver's license？Before people retire，they usually plan to do a lot of great things，which they never had time to do while working．But soon after retirement，all of the hobbies become as boring as the jobs they （69）left/have left（leave）．And，like the children in January，they go searching for new toys．Therefore，it is high time that you （70）added/should add（add） variety to your daily life．
10．Old age may not sound （61）exciting （excite）．But recent findings provide good news for older people and for people （62）worried （worry） about getting older．
The findings came from （63）a survey of more than 340，000adults in he United States．The Gallup Organization questioned（ 64）them by telephone in 2008．At that time，the people were between the ages of eighteen and eighty-five．
The researchers asked questions about emotions like happiness，（65）sadness（sad） and worry．They also asked about mental or emotional stress．The research team found that levels of stress were （66）highest （high） among adults between the ages of twenty-two and twenty-five．Stress levels dropped （67 ）sharply （sharp） after people reached their fifties．
Happiness （68）was highest among the youngest adults and those （69）in their early seventies．The study also showed that men and women have similar emotional patterns as they grow older．（70 ）However，woman at al ages reported more sadness，stress and worry than men．
