听第10段材料,回答第17至20题。
The first bicycle appeared in France in the 1790s.It was a little wooden horse with a fixed front wheel.Because the wheel was fixed,it could not be turned right or left.The only way it could be controlled was by the
rider pushing against the ground with his or her feet.In 1817,a German replaced the fixed front wheel with one that could be turned.Now the wooden horse could be directed right or left.The rider still needed to push it with his or her feet on the ground.In 1839,a Scottish MacMillan designed the first bicycle-like machine with foot board and rode it for 40 miles in only 5 hours.The bicycle got more comfortable in 1869 when rubber tires were introduced.Around the same time,the front wheels began to grow larger while the back wheels got smaller.During the 1880s,bicycles enjoyed a sudden growth in popularity.However,they weren’t very safe.Sitting high up towards the front of the bicycle and traveling very fast,the rider could be easily thrown over the front wheel if the bicycle hit a small stone.Fortunately,the “safety bicycle” was invented in 1884.The safety bicycle had equal-sized wheels and tires with air in them.And more improvements quickly followed.No doubt there will be further improvements in design and materials in the future.
17.What’s the talk mainly about?
A.The development of the bicycle.
B.The materials of making the bicycle.
C.The process of the bicycle’s becoming popular.
答案A
18.What is the disadvantage of the bicycle before MacMillan’s design?
A.The bicycle couldn’t change directions.
B.The wheels of the bicycle weren’t well fixed.
C.The rider’s feet couldn’t leave the ground.
答案C
19.When was the size of the bicycle’s wheels changed?
A.In 1817. B.In 1839. C.In 1869.
答案C
20.What happened in 1884?
A.Bicycles first had rubber tires.
B.The “safety bicycle” appeared.
C.Bicycles could run faster.

Kangaroos have long been a nuisance to many Australian farmers.Keeping these kinds of animals away from their crops and water supplies has become a continuous fight.A traditional way has been a series of the huge screaming (尖叫) from loudspeakers.Researchers have found that kangaroos often become used to these man-made sounds and take little notice of them.
Australian farmers could be about to get an unusual new weapon (武器) to protect their crops from kangaroos.Researchers in Melbourne have found that kangaroos can be frightened away by the loud sound of their own large feet.It appears to be quite a breakthrough.This is the noise these animals make when they feel danger before running away quickly.Using the animals’ own alarm system could be what angry farmers have been looking for.
Animal rights protectors are happy about this new finding.When people complain that the number of kangaroos has risen quickly,they see that a large number of kangaroos have been killed or injured on Australian roads by cars and trucks.Also,they don’t want several million to be shot dead every year by human beings.Researchers,who are hoping to develop their footstep sound technology,believe it could also be used to lead kangaroos away from busy highways.The protectors are in favour of this solution which can prevent kangaroos from being harmed and also please the farmers.

A small insect is getting a lot of attention in the United States.The rusty patched bumblebee(大黄蜂) is the first of its species to be declared endangered in the lower 48 states—meaning every state except Alaska and Hawaii.The rusty patched bumblebee is named for a rust-coloured line on its back.
The U.S.Fish and Wildlife Service announced this month it was adding the bee to its endangered species list.The insects are “on the brink of extinction”,according to the service.It said the bees were once found in 28 states.But there now are only small populations remaining in 13 states.The government agency will make a plan to help the dying bees recover.The agency said that such a plan might help other insects,like butterflies.
U.S.officials think land owners can take small steps to help the rusty patched bumblebee.They say land owners can be friendlier towards bees by using native plants in their gardens.The insects directly fertilise many kinds of fruit and vegetable crops.And they fertilise grain crops used to feed cattle and milk cows.It costs billions of dollars to duplicate the job the bees do for free.Land owners are also being urged to cut back on their use of pesticide products.The officials also suggest that gardeners leave their plants alone at the end of the summer instead of cutting them.That way,the bees will have a place to live over the winter.
The Fish and Wildlife Service says the rusty patched bumblebee was added to the endangered species list partly because of habitat loss.Other reasons were disease,pesticides and climate change.Officials are worried that other bees will suffer,too.Another species of bees in Hawaii is also endangered.
【语篇解读】本文介绍了在美国濒临灭绝的锈迹大黄蜂的情况以及采取的保护措施,并说明了其灭绝的原因。

解析推理判断题。根据第三段中的“Theofficialsalsosuggestthatgardenersleavetheirplantsaloneattheendofthesummerinsteadofcuttingthem.Thatway,thebeeswillhaveaplacetoliveoverthewinter.”可知,官员们还建议园丁们在夏末的时候不要修剪植物,而是将它们留在园中。这样,蜜蜂就有地方过冬了。由此推知,定期剪植物对锈迹大黄蜂是有害的。故选D项。
26.Whatcanweknowabouttherustypatchedbumblebeeaccordingtothetext?

Located in the Indian Ocean,the Maldives(马尔代夫) are among the most beautiful islands in the world,with white sandy beaches,clear water,and amazing coral reefs(珊瑚礁).The country depends on tourism,fishing,and shipping.But the rising sea level and the carbon pollution causing warming oceans are threatening(威胁) their existence.
The Maldives have asked for international help.They are a tiny country.The World Bank,the United States,the European Union,and many other groups have offered money to develop safeguards against climate change.
To protect the islands,the Maldives have built sea walls and increased the elevation(海拔) of important buildings and services such as the two international airports,which lie just 165 feet from the coastline.
They’re also building up islands such as the Hulhumale.The new island is surrounded by 9-foot sea walls.More than 40,000 people live there.The plan is to house 240,000,providing new opportunities for jobs.The goal is an excellent planned community with sustainable housing and buildings sensitive to the environment and needs of the people.
The government will move people living on smaller,lower-lying islands to the new built-up islands.The new islands offer free houses,new schools,health hospitals,fresh water,and waste treatment.Depending on tourism,the country hopes to build 50 more tourist islands.
“Climate change is happening,but we are not leaving the Maldives to the sea,” said Environment Minister Thoriq Ibrahim.The Maldives will protect their islands,people and tourism with new islands and ongoing island development against the rising sea level.

When your guests step into your home,should you,or shouldn’t you,ask them to remove their shoes?Are shoe bacteria something we should really be worried about in our homes?
The average shoe harbors(窝藏) hundreds of thousands of bacteria per square inch.The bottoms of our shoes are essentially a meet and greet for these bacteria,and with each step we take,we pick up new ones.Wherever you go,you’re going to be picking up them.But exactly what types of bacterial communities are hanging out on our shoes,and do they present a health threat?Almost all shoes were coated with all kinds of bacteria.While many types are harmless to humans,some can cause severe diseases,such as skin infections,and infections of the blood and the heart.
But despite the horrifying picture,there isn’t anything too serious to worry about.While many of us might want to take a house-cleaning step at the thought of shoes,the reality is that the load of bacteria our shoes bring indoors isn’t typically high enough to make the average healthy person very sick.For a healthy individual,bacteria on shoes likely have no risk.
Another point is that most of us don’t spend a lot of time on the ground,where shoe bacteria stay.The exposure makes the poison.So if you’re not exposed to it,you’re not going to get sick from it.In some cases,layers of bacteria coating the floor can enter the air we breathe,lifted by the wind from a window.That might increase infection risk.But the greatest threat really lies on the ground.We should be more worried about a child crawling around on the floor.For a healthy adult,it’s not too big of an issue.
For the average household,shoe bacteria don’t have an immediate risk.Healthy bacteria keep us healthy and protect us from other bacteria that can cause us illness.For most healthy persons,however,you can make the decision of taking your outdoor shoes off as much based on preference and habit.

B.Why Do Some Places Do Harbour More Bacteria?
C.Should You Take Off Your Shoes Indoors?
D.Could Humans Live Without Bacteria?

HowtoBeEco-friendly
If you’d love to be more eco-friendly but don’t know where to begin,start with a few small changes.　36　 
LoweringYourEnergy
Turn off lights and unplug power strips (电源插板) that you’re not using.　37　 Since some devices can still use energy even when they’re turned off,turn off these power strips at night to completely cut off energy use.If you need to leave your computer,or TV on,try setting it to sleep mode instead of simply leaving it on. 
UsingPublicTransportation
　38　 Keeping cars off the road in rush hours can also improve the air quality.If you do need to drive somewhere,ask friends if they’d like to carpool (拼车),so fewer cars are on the road. 
　39　 
Say no to unnecessary plastic straws,lids,and bags and stop using plastic wrap and plastic containers for food storage.Instead,you can use reusable water bottles made of sustainable materials like glass,bamboo,and ceramic.
ConsideringGrowingaPlant
They add more oxygen to the air,which means the less polluted air.If you don’t have a green thumb,choose some plants that are rather easy to look after.　40　 If possible,grow more than one plant. 

A.Reduce your gas consumption and carbon emissions by walking,biking,or taking the bus.
B.Here are some suggestions for you to live an eco-friendly life.
C.Use less energy during the hot summer months and cold winter season.
D.This is an easy way to reduce energy use.
E.Using items more than once.
F.Cutting Back on Plastics and Waste
G.“Lucky Bamboo” is especially good for that,since it demands nearly no attention.
答案与解析
【语篇解读】本文主要介绍了一些保护环境的方法,如降低能源、使用公共交通、减少塑料和废物、种植物等。
36.B　分析文章可知,文章采用了总分结构,第一段为总起段,因此最后一句需起到总起作用,引出下文介绍的一些保护环境的方法,B项符合语境。
37.D　第二段第一句提到“Turnofflightsandunplugpowerstrips(电源插板)thatyou’renotusing.”,这是一件非常简单的,随手就可以做的事,故D项符合语境。
38.A　第三段的主旨大意是使用公共交通,A项中提到,步行、骑自行车或乘坐公交车可以减少尾气和碳排放,符合第三段的语境。
39.F　空格处是段落小标题。第四段提到要拒绝使用不必要的塑料吸管、盖子、塑料袋,不要使用塑料袋来储存食物。F项提到减少塑料和废物,符合第四段的语境。
40.G　最后一段提到可以养一些比较容易照顾的植物。G项中提到“LuckyBamboo”就是一个特别好的选择,因为它几乎不需要怎么照顾就可以生长。由此可判断G项是对前文的进一步解释,符合语境。
第三部分　语言运用(共两节,满分30分)
第一节(共15小题;每小题1分,满分15分)

答案与解析
【语篇解读】全文介绍了熊猫妈妈悉心照顾熊猫宝宝直至其独立生活的情况。
56.is loved　考查动词时态和语态。句意:大熊猫为全世界人们所喜爱。故此处使用一般现在时的被动语态,填isloved。
57.recently　考查副词。应用副词修饰句子,表示时间“最近”,故填recently。
58.caring/careful　考查形容词。应用形容词修饰名词mother,且根据下文可知熊猫妈妈非常细心,因此填caring或careful。

Dear fellow students, 
Our school has started a programme of garbage sorting.It is my great honour to represent the Students’ Union to make our voice heard on it.
As we all know,we produce lots of garbage,such as leftover food,waste paper and plastic bottles every day,which becomes a big headache in our life.Therefore,garbage sorting is a good way of dealing with it.It is beneficial to us in the following ways.To begin with,we can recycle what can be reused to save more resources.Besides,harmful materials in the sorted garbage can be properly treated to avoid environment pollution.As students,we are supposed to tell different types of garbage and put them in different dustbins to make recycling easier.
Now I am here to call on everyone to take action together to make the environment clean and beautiful.
Yours,
Li Hua 
第二节(满分25分)
阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Robert and Henry were two friends in the same class.They always played together and went home together.One day,Robert and Henry were going home from school.When they were turning a corner,Robert cried out,“A fight!Let’s go and see...”
“No,” said Henry.“Let us go quietly home and not meddle with (插手) this quarrel.We have nothing to do with it and may get into trouble.Also our parents are expecting to have dinner with us together at home and I don’t want them to worry about me.”
“You are a coward(懦夫),and afraid to go,” said Robert,and off he ran.Henry went straight home,and in the afternoon went to school as usual.
But Robert had told all the boys that Henry was a coward,and they laughed at him a great deal.From then on,they looked down upon Henry and didn’t want to play with him together.
Henry was sad but he wasn’t angry with Robert for his rude behaviour,because he knew that they misunderstood him,and that he ought to be afraid of nothing but doing wrong.Thus,he just ignored(忽略) the other boys’ laughter and continued to go to school and study as well.However,Robert didn’t invite Henry to go home with him anymore.Instead,he had some other boys who also thought Henry was a coward.Every day after school,they didn’t go home directly but went to the river or somewhere to play games and had a lot of fun.
A few days later,Robert was bathing with his new friends in a river,and got out of his depth.He struggled and cried for help,but he failed.The boys who had called Henry a coward got out of the water as fast as they could,but they did nothing to help him.

ItseemedasifRobertwouldbedying.Just at the moment,Henry happened to be passing by.Hearing the screams,Henry ran to the riverside,threw off his clothes and jumped into the water without hesitation.He reached Robert just as he was sinking the last time.By great effort,and with much danger to himself,he brought Robert to the shore.
Thus,Robert’slifewassaved.Robert and his new friends were ashamed at having called Henry a coward.They realised that Henry had true courage.They said sorry to Henry for their rude behaviour and asked for his forgiveness.Henry forgave them happily.He and Robert were friends again and they went home together as usual.From this,Robert learned what true courage was:never be afraid to do good,but always fear to do evil.
