解答 61.are spending   62.beneficial   63.what    64.Considering  65.more
66.varies   67.how    68.on    69.weight    70.balanced
61.are spending 考查动词时态.and是并列连词,它前后连接两个相同的语法成分,become与spend都要用现在进行时态.
62.beneficial 考查形容词.根据句意,空格处用形容词形式作句子的表语,名词benefit的形容词是beneficial.
63.what 考查代词.此处what引导宾语从句,在从句中what作动词eat的宾语. 
64.Considering 考查现在分词.句中缺少连词,用现在分词短语作状语.
65.more 考查形容词比较级.根据句意,句子中有比较级的关键词than,所以要用比较级,多音节形容词的比较级形式是在单词前面加more.
66.varies 考查动词的时态.本文通篇运用了一般现在时,句子主语the number是单数,谓语动词也要用第三人称单数形式.
67.how 考查副词.active是形容词,要用副词修饰,how引导宾语从句作depending on的宾语. 
68.on 考查固定搭配.on the other hand意为"另一方面",是固定搭配.  
69.weight 考查名词.根据句意,空格处应该用名词形式,put on weight是动词短语,意为"体重增加". 
70.balanced 考查分词作形容词.此处过去分词作形容词,balanced diet意为"健康的饮食".

3.The plan had been made to create a beautiful nature park with a large man-made lake on the outer parts of the city of Zhengzhou,the capital of Henan Province.However,thanks to a terrible trick played by nature,what the officials have ended up with,is a natural sandy mess!
The government wanted to create a beautiful place where people of this busy industrial city could come to relax.But things did not quite turn out that way---shortly after digging up thousands of tons of sand,the underground water dried up.As a result,the dry sand has changed into a Sahara-like desert.While official reports show that the sand is piled up to 10meters high,some people say that it is ten times more or about a 100-feet high in certain areas.
If that is not bad enough,the sand hills that now spread across an area the size of four football fields,have influenced the environment.What's worse is that on windy days,the dry sand moves into the city center,making it almost impossible to drive and forcing people to wear face masks and protective eyewear to prevent the sand from getting into their eyes,nose,and mouth.
In an act of trying to keep the sand and provide the illusion(幻想) of green fields,the officials have even tried covering it with a green plastic netting.However,that has not done much to improve the terrible situation!
As you can imagine,many of Zhengzhou's residents are upset by the disaster.They think that desert wasteland that looks nothing like the green landscape they were promised,has resulted in polluting their pleasant city environment.Some think it is even stopping businessmen from coming to the city.

4.Last week I visited one of my old neighborhoods in Washington D.C.I had not been there for twenty years and as I walked along the street,my mind was flooded by memories of the past.I saw the old apartment building where I had lived and the playground where I had played.As I viewed these once familiar surroundings,images of myself as a child there came to mind.However,what I saw and what I remembered were not the same.I sadly realized that the best memories are those left untouched.
My old apartment building,as I remember,was bright and alive.It was more than just a place to live.It was a movie house,a space station,or whatever my young mind could imagine.I would steal away with my friends and play in the basement.This was always exciting because it was so cool and dark,and there were so many things there to hide among.There was a small river in the back of the building.We would go there to lie in the shade of trees and enjoy ourselves.
However,what I saw was completely different.The apartment building was now in disrepair.What was once more than a place to live looked hardly worth living in.The windows were all broken.The once clean walls were covered with dirty marks.The river was hardly recognizable.The water was polluted and the trees and flowers were all dead.The once sweet-smelling river now smelled terrible.It was really heartbreaking to see all this.
I do not regret having seen my old neighborhood.However,I do not think my innocent childhood memories can ever be the same.I suppose it is true when they say,"You can never go home again."

A.Quite excited.
B.Very sad.
C.Very regretful.

56."You can never go home again"in the last sentence of the passage means thatC.
A.a visit to one's hometown will bring back many sad memories
B.one should never revisit his hometown after many years of absence
C.one will never find his hometown the same as it was in his childhood memory
D.a visit to one's hometown will bring back one's pleasant memories of home.
5.In order to help customers find what they want quickly,it's important to keep the thousands of titles in the Main Street Movies store organized properly.This section of the Employee Handbook will tell you how to organize videos.
Each Main street Movies store has three main sections:
New Releases Wall.
Film library.
Video Games.
New Releases Wall.Almost 70percent of movie rentals are new releases,and that is the first place where most customers go when they enter the store.The center section of shelves on this wall holds Hottest Hits.When new titles come into the store,place them on this wall in alphabetical order.The shelves beside Hottest Hits are called Recent Releases.The New Releases Wall,including the Hottest Hits and Recent Releases shelves,holds about 350titles.
Film Library.The thousands of titles in the Film Library are organized into categories.The films within each category are displayed alphabetically.Here are the categories and their two-letter computer codes:
ACActionDRDramaHOHorror
CHChildrenFAFamilyMUMusic
COComedyFLForeign LanguageSCSCIENCE Fiction
*Foreign Language titles include films that were originally made in a foreign language and films with foreign language subtitles.A sticker on the back of each box tells which type of film it is.
Video Game.All the video games in Main street Movies are arranged in alphabetical order.Although video games represent only a small percentage of our inventory(库存),they are stolen more often than any other type of goods in our store.Therefore,video games are never displayed on the shelves.Shelves in the Video Game section hold cardboard with pictures and information about each game.When a customer wants to rent a particular game,you then find the game from the locked case behind the counter.

6.COPENHAGEN-The world is gathered in Copenhagen for the U.N.climate summit,but Denmark's bicycle-friendly capital has also given its name to a movement of cities trying to find a kinder way to travel to and from work.
Nearly 40 percent of Copenhagen's population cycle to work or school on ubiquitous(无处不在的) paved cycle paths.Many residents take to their bikes year-round,braving rain and snow through the winter in a city where the bicycles outnumber the people.
Amsterdam and Beijing too are known for their bicycles,but the Danish capital is where urban planners from around the world have been looking for ways to get their people out of cars and up onto bikes,an effort known as Copenhagenisation.
Klaus Bondam,Copenhagen's technical and environmental chief,calls himself a"mega cyclist"and says the bike's popularity stems partly from high taxes on cars which meant working-class Danes could not afford to drive in the 1930s and 1940s."Today you'll meet everybody on the bicycle lanes-women and men,rich and poor,old and young."Bondam said.
The local government has during the last three years invested more than 250 million crowns ($49.42 million) in bicycle lanes and to make the traffic safer for bicyclists.Today around a third of the population drive cars to work or study,another third take public transport,while 37 percent cycle--a figure the city aims to increase to 50 percent by 2015.
There are many benefits when citizens choose bicycles over cars:pollution and noise decline,public health improves,and more people on bikes or walking creates a sense of safety in the city.Fewer parked cars leaves more space for playgrounds,parks,shopping areas and other useful public places.

A.a city without cars

D.the U.N.climate summit

A.there is no path for cars during rainy and snowy days
B.citizens are limited to have only one bike for each person
C.two-thirds of people in Copenhagen cycle to work or school
D.city planners try their best to encourage more citizens to ride bikes
55.Bikes are popular in Copenhagen partly becauseD.
A.the citizens are unable to afford to buy a car
B.the rich tend to keep fit by cycling to work
C.young people regard cycling a fashion to follow
D.high taxes were paid for cars in the 1930s and 1940s
