14.Four common bad habits combined-smoking,drinking too much,inactivity and poor diet-can age you by 12years,sobering new research suggests.
The findings are from a study that tracked nearly 5,000British adults for 20years,and they highlight yet another reason to adopt a healthier lifestyle.
Overall,300people studied had all four unhealthy behaviors.Among them,90died during the study,or 30percent.Among the 400healthiest people with none of the four habits,8percent of them died.
The risky behaviors were:smoking tobacco; downing more than three alcoholic drinks per day for men and more than two daily for women; getting less than two hours of physical activity per week; and eating fruits and vegetables fewer than three times daily.
These habits combined substantially increased the risk of death and made people who engaged in them seem 12years older than people in the healthiest group,said lead researcher Elisabeth Kvaavik of the University of Oslo.
The healthiest group included never-smokers and those who had quit; teetotalers,women who had fewer than two drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly; and those who ate fruits and vegetables at least three times daily.
"You don't need to be extreme"to be in the healthy category,Kvaavik said."These behaviors add up,so together it's quite good.It should be possible for most people to manage to do it."
The US government generally recommends at least 4cups of fruits or vegetables daily for adults,depending on age and activity level,and about 2hours of exercise weekly.

60.What problem may you have,if you smoke often and eat few fruits and vegetables?C
A.You would have difficulty in walking.   B.You would feel tired,lack of energy.
C.You may look older than you really are. D.You may face the risk of death of cancer.
61.How many of the 400healthiest people with none of the four habits died?A
A.32.      B.24.            C.56.            D.120.
62.What does this text mainly talk about?B
A.Suggestions to smokers.        
B.The results of four bad life habits.
C.The findings of a new research.         
D.The recommends from the US government.

5.American cities are similar to other cities around the world:In every country,cities reflect the values of the culture,American cities are changing,just American society is changing.
After World War II,the population of most large American cities decreased; however,the population in many Sun Belt cities increased.Los Angeles and Houston are cites where population moves to and from the city reflect the changing values of American society.In the late 1940s and early 1950s,city residents became wealthier.They had more children so they needed more space.They moved out of their apartments in the city to buy their own homes.They bought houses in the suburbs.
Now things are changing.The children of the people who left the cities in 1950s are now adults.Many unlike their parents want to live in the cities.They continue to move to Sun Belt cities and older ones of the Northeast and Midwest.Many young professionals are moving into the city.They prefer the city to the suburbs because their jobs are there,or they just enjoy the excitement and possibilities that the city offers.
This population shift is bringing problems as well as benefits.Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent.In the 1950s,many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.
Only a few years ago,people thought that the older American cities were dying.Some city residents now see a bright new future.Others see only problems and conflicts.One thing is sure:many dying cities are alive again.

34.Why did American city residents want to live in the suburbs after World War II?B
A.Because cities contained the worst parts of society.
B.Because they were richer and needed more space.
C.Because older American cities were dying.
D.Because they could hardly afford to live in the city.
35.What does the author think of cities all over the world?A
A.They are similar. B.They are different.
C.They are alive.   D.They are hopeless.
36.The underlined word‘shift'(Para.4)probably means‘C'.
A.explosion      B.growth    C.change    D.reduction
37.According to the 4th paragraph,a great many poor people in American citiesA.
A.a(chǎn)re faced with housing problems       B.a(chǎn)re forced to move to the suburbs
C.want to sell their buildings          D.need more money for daily expenses
38.We can conclude from the text thatC.
A.American cities are changing for the worse
B.many people are now moving from American cities
C.people have different views on American cities
D.the population is decreasing in older American cities.

2.Whether it's for a hobby or profession,photography has always been highly valued.Photography has been around for over a hundred years,but what has recently revolutionized it is digital photography.
A digital camera looks like a film camera,but it works differently.A digital camera takes pictures or a video by using a CCD sensor instead of film.The data about the images are electronically saved on a flash card.Later on,the flash card can be removed from the camera and put into a card reader.The card reader can be plugged into a computer's USB port.The images and videos can then be saved on a computer for viewing,editing,emailing,or printing.
Digital photography received a great deal of criticism in its beginning stages,but with its continued development,it is now capable of producing images of a quality that is similar to.or even better,than that of film photographs.However,what really makes digital photography attractive is its convenience and low cost.Instead of having to go to a lab and waiting to get pictures developed to see what they look like,you can always view the images or-video on the LCD screen that is on the back of the camera.Not only does this feature save time,but it also prevents common mistakes like using a wrong exposure(曝 光) that could ruin an image or video.
With the usage of computer programs like Photoshop,more serious photographers can edit their images without the expense of a darkroom.Digital photography is also friendlier to the environment,as harmful chemicals that are needed in the development of film are not used in digital photography.Printing only the best pictures and not having to buy film make digital photography much cheaper.
25.In a digital camera,an image is taken by the camera'sC.
A.card reader                               B.film
C.CCD sensor                              D.USB drive
26.Why did the public first disapprove of digital photography?A
A.The pictures were not as good as those by a film camera.
B.It used dangerous chemicals to develop its pictures.
C.The computers were too expensive for people to use.
D.It wasn't convenient to use because of its techniques.
27.Which is NOT a reason why digital photography is eco-friendly?D
A.Harmful chemicals are not needed in developing pictures.
B.Pictures are printed with a computer instead of films.
C.Photographers don't have to work in a darkroom.
D.Digital cameras produce pictures as good as film cameras.

9.Not for the first time,Paul Mathis wants us to change.But this time he isn't trying to get us to go vegetarian,or dine only on locally grown ingredients.This time he's trying to get us to type differently.
Paul Mathis,a restaurateur from Melbourne who owns a string of dining establishments,has designed the letter"?"-representing the word"the".Now he is pushing Apple to allow him to promote his app,which features the new character,in its iTunes store.
   In a move to branch out of the food business,Paul has invested AUS $38,000 (£23,500)in the new app,but has so far been rejected by Apple.He is hoping he can change their mind,pointing out that reducing the word"the"-the most used word in the English language-to one character would be helpful for Twitter and swift typing.
"Is this important?"he said,in an interview with The Sydney Morning Herald."No.Is this going to change the world?Not really.But is it something that might be useful for people?I think so,because it can save people lots of time on keyboard."
"The word‘a(chǎn)nd'is only the fifth-most used word in English and it has its own symbol-the ampersand‘&',"said Mr.Mathis."Isn't it time we gave the same respect to‘the'?"
The top five most commonly used words in the English language are said to be:the,be,to,of,and"and".The ampersand"&"has at times been used as the 27th letter of the English alphabet.
Paul has developed the typography-effectively an upper-case"T"and a lower-case"h"bunched together so they share the upright stem-and an app that puts it in everyone's hand by allowing users to download an entirely new electronic keyboard complete not just with his symbol but also a row of keys of 15 most frequently typed words.
So far,though,the take-up has been minimal.But that might change if he can get his innovation into Apple's app store.The problem is,the Californian tech giant has so far resisted his advances.But who knows-maybe in 500 years'time people will be amazed that there was a time when we didn't use‘?'.
(Note:Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS)
78.What is Paul Mathis?He is a restaurateur from Melbourne owing a string of dining establishments
79.Paul designs the new letter"?"to represent the word"the"because he thinksit would be helpful for Twitter and swift typing
80.The main difference between the new and the old electronic keyboard is that the new onecontains"?"and a row of keys of 15 most frequently-used words
81.How can Paul attract more people to download his new keyboard?By promoting his app in iTunes store.

6.With more and more cars on the road,traffic jams are inevitable. Traffic jams can lead to increased accidents as there are more cars,with more people trying to get to their destination,all the while getting worse.Although it's impossible to avoid traffic jams altogether,there are some tips you can follow to reduce the amount of time on the road.
Check for traffic jams before you leave.You can listen to the radio for traffic news,or check on the Internet to get up-to-minute information on traffic.If the route you want to take is heavy with traffic,you can choose another.
Look for a different route all the time.Most traffic jams happen on busy roads.Using country roads could see you avoiding a lot of traffic.Although the distance you may have to travel is further,it can work out quicker.
Set your car radio to receive traffic bulletins. Many new car stereo systems (汽車音響系 統(tǒng)) are equipped with a radio system by which you can hear the traffic channel.This way you can get the latest traffic information and change your journey if necessary.
__________ Most traffic jams usually occur during rush hour,so try to avoid this time period if possible.Some jobs offer flexible working hours so that you can travel to work outside of rush hour.Some jobs even allow you to work at home so as to avoid moving altogether.Ask your manager to see what you can do if traffic is a problem for you.
Use public transport alternatives where available.The easiest way to avoid traffic jams is to take buses or the underground instead of driving your own car.Not only will you avoid traffic jams but you will most likely be saving money as the cost of motoring rises.
66.The underlined word"inevitable"in Paragraph 1 probably meansB

3.Each food we eat tastes different,and there are untold numbers of different tastes.Still,all flavors are based on just four basic tastes:sweet,bitter,salty,and sour.Some food experts argue there is a fifth basic taste called umami(a Japanese word that can be translated roughly as"tasty"or"savory"),but this theory remains controversial.Regardless of whether there are four or five basic tastes,the number is small.
How can so few basic tastes give rise to the enormous number of flavors we experience?This is possible because the basic tastes combine in different proportions.Compare this to colors.There are only three basic colors-yellow,red,and blue-but when mixed in different ways and proportions,these three basic colors are sufficient to create the vast array of colors that we see every day.
Apart from being influenced by different combinations of the basic tastes,the experience of taste is also enriched by other sensations,such as odor and temperature.These functions together produce what we recognize as unique tastes.In fact,what we perceive as taste often involves smell more than the taste experienced through the tongue.This is why foods with strong tastes often seem bland to people who,due to a stuffy nose,cannot smell them.For example,cinnamon tastes quite mild to people who cannot enjoy its fragrant smell.The same is true of drinks,like hot coffee or tea,which taste best when they can be smelled as well as tasted.
What can also contribute to the sensation of taste is our ability to feel pain.The reason why hot,spicy foods like chili peppers are tasty is that they affect the lingual nociceptors.Nociceptors are small areas on the surface of the body that help protect us against injury.Nociceptors on the skin warn us of potential damage to the body.When we are pricked with a needle,for example,nociceptors represent that sensation as pain.A special kind of nociceptor called a lingual nociceptor is found on the tongue and,along with the other senses,helps us enjoy certain foods.

42.Which sentence best summarizes the main idea of the passage?B
A.New tastes can be created in laboratories.
B.Taste is a combination of different factors.
C.Solid foods have a stronger taste than drinks.
D.Taste is more important than smell for food.
43.Which word has the closest meaning to the phrase"give rise to"in Paragraph 2?D
A.lift              B.count             C.remove          D.produce
44.What does the author imply about cinnamon?B
A.It can relieve a stuffy nose.
B.It can have a very strong taste.
C.It should be kept in a cool place.
D.It tastes better in a large quantities.
45.What are"lingual nociceptors"?C
A.Foods that tastes hot and spicy like chili peppers.
B.Substances in a food that improve its flavor.
C.Areas on the tongue that sense spicy foods.
D.Small connections between the nose and the mouth.
