　　A

　　With more than 10,000 plants，the 68ft “living wall” near Victoria station will collect rainwater which falls onto the roof of the building and use it to nourish the plants.The result will be an eye­catching garden which brightens up the popular tourist route，near the Rubens at the Palace Hotel，and stops it from flooding.

　　Containing more than 20 seasonal plant species，the wall required 16 tons of soil and will be capable of storing up to 10,000 litres of water.The project，backed by London Mayor Boris Johnson，was launched with the aim of dealing with a key environmental challenge in London.

　　According to the Environment Agency，there are around 534,000 properties in London on the Thames flood plain and one in four are at risk of flooding.This is partly due to the low absorbency of urban surfaces.

　　Matthew Pencharz，the Mayor’s Advisor for Environment and Energy，said，“London has plenty of trees，parks，gardens and increasing numbers of living roofs，which can increase resilience(适应力) to extreme weather.The Mayor is encouraging more green programs like the living wall to make sure London can continue to compete，not only as the greenest city in Europe，but as the best city on the earth.”

　　A similar living wall was built in Islington in 2005 but ended in disappointment after the watering system failed and all the plants died.

　　At that time critics accused the council of wasting 100,000 of taxpayers’ money on a “green extravagance(奢侈品)”．The Victoria project is believed to be the largest of its kind in the country.

　　Ruth Duston，CEO of Victoria BID，said，“Building the living wall has a long­term positive impact on the environment.It delivers a model of best practice for London.”

　　The flowers have been chosen to ensure the wall is in bloom all year round，attracting wildlife such as birds，butterflies and bees.

　　Armando Raish，managing director of Treebox，said，“Due to the variety of plants，we expect the living wall to significantly increase the number and variety of bugs and bees in this part of Victoria.”

　　1．The “living wall” was designed to

　　.

　　A．display some unusual plants

　　B．prevent flooding when it rains

　　C．store rainwater for the citizens

　　D．attract more tourists to London

　　答案　B

　　解析　细节理解题。根据第一段的内容可知，这道种植植物的墙建在维多利亚火车站附近，目的是用雨水浇这些植物，预防伦敦市区泛滥成灾。

　　2．The underlined word “backed” in Paragraph 2 probably can be replaced by

　　.

　　A．criticized

　　B．constructed

　　C．supported

　　D．rejected

　　答案　C

　　解析　词义猜测题。从第四段中伦敦市长顾问的话“The Mayor is encouraging more green programs like the living wall to make sure...”中可以推断出，市长对该项目的态度是支持的。画线的单词back意为“支持”，可被support代替。criticize批评；construct建造；reject拒绝。

　　3．Why are 25% of the buildings on the Thames flood plain at risk of flooding?

　　A．Because the buildings are near the river.

　　B．Because it rains heavily all the year round.

　　C．Because there are few trees and plants in London.

　　D．Because the ground doesn’t absorb much rainwater.

　　答案　D

　　解析　细节理解题。根据第三段的内容可知，在伦敦市的泰晤士河的洪泛区，有大约534 000处房产，其中的四分之一面临被淹的危险。部分原因是城市地表的吸收能力低。

　　4．Which would be the best title of the text?

　　A．A Beautiful Garden City

　　B．London’s Living Wall of Green

　　C．More Species in Central London

　　D．Creative Way to Fight Flooding

　　A postgraduate student in France took to his microblog to complain about having to do shopping for relatives and friends.

　　The microblog post has drawn wide attention on the Internet and many students said they were tired of shopping for friends in China as it was interfering with their studies.“I am a postgraduate student，not a professional purchaser，” said the student in France，identified as Li Yuandong.

　　As a science student，Li said，“I am not a fashion expert，I am a scientist，but I know about the latest items of Louis Vuittion and I can distinguish various types of perfume，nail polish，and face lotion.”

　　Li’s story drew heated discussion on the Internet among other students studying abroad.

　　“This is so typical.Mine is worse because I live in a village far away from Paris.It takes me hours to get to Galleries Lafayette，but I have to go there every week.”

　　“I don’t know how much money I have spent on train tickets，but nobody seems to care，” a girl，identified by her Internet name of Jarlay121，said.

　　Another student studying in Britain said that once her cousin asked her to buy 20 packs of diapers(尿片)，two toilet lids and a bumper(缓冲器) for a Toyota car.

　　“Every time I am at the airport，I hold up the queue at security checks and I have to pay extra money for overweight packages.I cannot ask them to pay for that because they are all my relatives and friends，” said a Shenzhen girl name Zhu Jingtong.Zhu is now studying in the United States.

　　Although some students make money from shopping for those in China，many others would rather spend more time studying and enjoying life in another country.

　　“It is risky because we may be charged for avoiding taxes or even smuggling(走私)．Once I was scared because I had five iPhones for my relatives in my luggage.If customs had caught me，I could have got into a lot of trouble，” Zhu said.

　　5．The main reason why some students were tired of shopping is that

　　.

　　A．they don’t like shopping frequently

　　B．their studies are interfered by too much shopping

　　C．they have to pay extra money for overweight packages

　　D．they have to spend a lot of money on train tickets

　　答案　B

　　解析　细节理解题。由第二段第一句中的“it was interfering with their studies”可知海外留学生们厌倦替亲友购物的最主要原因是学业受到了影响，故选B。

　　6．Which of the following statements is NOT true according to the passage?

　　A．Customs can charge those who avoid taxes or smuggle goods.

　　B．Not all students make money from shopping for their relatives or friends.

　　C．The students will be paid back if they pay extra money for overweight packages.

　　D．Some of the goods can’t be bought where the students live.

　　答案　C

　　解析　推理判断题。由最后一段可知A正确；由倒数第二段可知B正确；由第五段可知D正确；由倒数第三段可知，由于超重而自己付的钱是无法向亲友开口要的，故选C。

　　7．It can be inferred from the passage that some students studying abroad

　　.

　　A．have to shop for others though they don’t want to

　　B．have to pay for shopping for others

　　C．have to avoid taxes for shopping

　　D．have to be checked if packages are overweighed

　　答案　A

　　解析　推理判断题。根据文章内容可知，海外的留学生帮国内亲友购物这一事情已经给他们带来了困扰，尽管他们不愿意这样做，但也开不了口拒绝。故选A项。

　　8．What would be the best title for the passage?

　　A．Life with Too Much Shopping

　　B．A Foreign Student’s Microblog

　　C．Overseas Students Tired of Shopping

　　参考范文

　　Ladies and gentlemen，

　　I feel it a great honor to have a chance to give a speech here，talking about fog and haze weather.Since the end of last year，fog and haze weather has occurred a lot in some areas of China, which has done great harm to our daily life.Many traffic accidents happened just because of the heavy fog and haze.Besides, more and more citizens have to go to see the doctor because of the serious disease caused by the fog and haze.

　　Now that we have realized the great harm caused by the fog and haze，we should take measures to reduce fog and haze weather.The government should suggest people go to work or school with the public transportation, such as the bus and the underground.Also more trees should be planted.As for me, I will go to school by bike or on foot.Would you join us in protecting the environment?

　　Thank you.
