AChina has announced it's abolishing its one-child policy.What difference has it made, statistically speaking?400million births preventedThe one-child policy,officially in place since1979,has prevented400million births.Parents have faced fines and other punishments for having more children.The majori ty of the decrease in China's fertility(生育)rate happened in the1970s.It dropped from5.8children per woman in1970t02.7in1978.Despite the one-child policy the rate had only fallen t01.7by2013.21:28baby death rateSince the one-child policy was introduced,baby girls have become more likely to die than boys.In the1970s,according to the United Nations,60males per l,000live births died under the age of one.For girls the figure was53.In the1980s,after the one-child policy became official, the rate for both was36.By the1990s,26males per l,000live births died before the age of one-and33girls.The2000s saw21boys per l,000live births dying and28girls.1.16boys born for every girlSexually selective abortions have been considered as a major cause of China's unusual sexual imbalance.Gietel-Basten,associate professor in social policy at Oxford University,says the births of many girls are not registered if parents have broken the rule by having two children,adding officials often turn a blind eye.It's estimated there are now33million more men than women in China.4:2:1familiesWith the ageing of China's population and the continuation of the one-child policy,a“4: 2:1”home is the description given to households in which there are four grandparents cared for by two working age parents,who themselves have one child.By2050,it's predicted that a quarter of China's population will be65or older.The predicted decline in the number of people of working age is thought to have persuaded the government to drop the one-child policy.21.When was the baby death rate for both boys and girls equal?A.In the1970s.B.In the1980s.C.In the1990s.D.In the2000s.22.What makes the one-child policy abolished according to the passage?A.The decline of birth rate.B.The rise of baby death rate.C.The change of family structure.D.The decline of working age people.23.The passage sums up the one-child policy by.A.numberB.exampleC.contrastD.analysisBlt's a little hard to figure out the rules for sure,but the baby African buffalo(7K午)seems to have the upper hand.The two stand a couple feet apart,staring at each other.Behind them,their mothers look on with the kind of indifference(不关心)of mothers everywhere who see their kids playing a harmless game.The alarm went off about half an hour ago,the second time tonight.Here,one bell means “elephant”,two,“rhino”(犀牛),and three and four,1really can't remember for what,because when you're awoken by bells in the middle of the night,your first thought won't be“Animal!”. But as soon as I realized it was the rhino alarm,I was running for the stairs.Yet I'm the only one watching the animals stare-down.Either everyone else died of a heart attack w hen the bells went off,or l was the only one in the entire hotel who didn't turn the alarm switch to off before going to bed.The Ark,a hotel shaped like the biblical ark(圣经的方舟),lies in the highlands of Kenya's Aberdare National Park,about100kilometers north of Nairobi.At the Ark's prow(船首)are huge windows overlooking a waterhole.Earlier tonight,I'd watched a pack of wolves,buffalos and elephants.And now,at three or so in the morning,I'm down for rhino bells.The first time,2.5 hours ago,it was a single black rhino,which came down,got a drink,and left.I'd have been sorry for the lost sleep.I've already arranged with a guide to take me out at sunrise for the so-called“should_never_miss”bird-watching,where we'll get to see30species, but really,how many times in your life will you get to wake up and say,“Wow!Rhino!”?Isn't that the definition of a pretty good night?Last week we went from Uganda into Kenya.Before I left home,1thought I'd be happy with ten elephants and five or six giraffes on the whole trip.I didn't dare to dream the rhino.24.The message that the hotel's bells sent was.A.a very wise way the author had never heard ofB.hard for the author to remember in detailC.a matter that all visitors had got used toD.like conditioned response training for animals25.What's the author's attitude toward the bell?A.It's bothering but two bells are welcome.B.It should be turned off whenever it rings.C.It lets visitors have a chance to see buffalos.D.It is a very bad way to wake the guests up.26.What can we learn from the passage?A.The author hates all the animals.B.There are lots of wild animals near the Ark.C.The author slept well during the whole trip.D.The author has no interest in thinos.27.What did the author see at about3:00a.m.?A.Two buffalos were fighting fiercely for food.B.A rhino and a buffalo were fighting for water.C.A rhino and a buffalo were staring at each other.D.A buffalo was teaching its baby to walk freely.CMany people trying to sell homes find that an increase in home prices has turned the market in their favor.But sellers can still get the short end of the deal if they aren't careful.Here are a few tips for you:Don't test your luck.Of course you think anyone who moves into your lovely home should be willing to pay top dollars,especially if you've recently invested in some improvements.But listing a home at a price that's too high above the market price could turn away some buyers.Buyers noticing that the home still hasn't sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price.And if a home hasn't received any offers after two weeks,it might be time to reset the price.A price that's too low can bring about an undesired outcome.Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers.But setting the price too low comes with several risks.One possibility is that buyers will get skeptical of the home that is listed for$15,000to $20,000less than similar homes in the area,especially if it's not properly marketed.Once again, people might assume there is something wrong with the home and may not bother to look at it.Spy on the competition.Going to other people's open houses can give you a better sense of how your home compares to others on the market.Check out the decoration in their kitchens,the size of their backyards and use the information to figure out where your home should fit in the range of the price.But don't set your pricing just on what you see elsewhere.28.What does the underlined part in Paragraph l probably mean?A.Be at a disadvantage.B.Get the upper hand.C.Have control over the situation.D.Be unable to fit in.29.What should home sellers do according to the passage?A.Price your house on the basis of its geographic location.B.Price your house slightly above the market price after decorating it.C.Change the price if no offer has been received within a week.D.Price your house at or slightly below the market price.30.If you set the price of your house too low,.A.buyers might think it not worthwhile to go to have a lookB.you are likely to come into conflict with the neighborhood sellersC.your house will be crowded with buyers within a couple of daysD.chances of your house being sold at a better price will be greatly increased31.What is the benefit of going to other people's open house?A.You can pick up some useful lessons on house selling.B.You can get your pricing mainly based on what you see elsewhere.C.You can work out how much money you should ask for your home.D.You can know how to make your house stand out against other houses.DWhat's your favorite type of music?Most people may prefer rock and roll,pop or jazz. These types are most publicized by television and the radio.Country music now would seem to mistakenly belong to the category of rock or pop.Publicity of this category started to drop only after the year2000;however,it did have its peak years just before falling down.What people may not know is that this type of music inspired(促成)rock and roll especially with one of the most important figures in music history-Elvis Presley-who is known as the6/King of Rock and Roll".Elvis used to be very famous at a radio program which broadcast country music back in the late1940s.Country music is influenced by jazz and blues.Rock music is also influenced by jazz and blues so that they may even seem similar.Nowadays,country music is closely related to pop music due to artists'preference and popular demand.Starting from the1980's it slowly divided itself into New and Old Country Music. Legends like Johnny Cash began to slip away because the new understanding of country music actually contains pop and his music just doesn't fit the category.Fortunately,country music is still heavily promoted through websites and reviews.Certain types of music nowadays are linked with different age groups.Classical for the people in the mid19th century,pop in the1920's,and then there's country music.All these types continue to grow and modernize while still appealing to certain age groups.More modern country music compositions tend to become different in their own ways which makes it even harder to identify them as country music while they,again,remain appealing only to certain age groups. Active promoters of country music videos,however,seem to appeal to a large number of age groups especially those active in Australia,for as long as country music isn't mixed with other types,it will eventually regain its charm as music for all ages.32.It can be learned from the first paragraph that country music____.A.is most publicized by television and the radioed to be liked by more people compared to jazzC.has become less popular since the year2000D.should be included in the category of rock or pop33.What is the relationship between rock music and country music?A.Both types influenced the formation of rock and roll.B.Presley turned pop music into country music.C.They are both influenced by jazz and blues.D.The use of the same instruments makes them sound similar.34.Some legends of country music began to slip away because____.A.their songs totally changed the style of country musicB.they began to work on pop music for more profitsC.there is no marketing space for country music anymoreD.they can't meet the popular demands on country music35.The author seems to believe that____.A.country music should keep its own style to attract more listenersB.it's necessary for country music to be mixed with other typesC.only a certain age group of people will like country music in the futuremon characteristics can be found in all modern music第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
