17．Can youmake out（理解）what she's trying to say？

14．Ask someone what they have done to help the environment recently and they will almost certainly mention recycling．Recycling in the home is very important of course．However，being forced to recycle often means we already have more material than we need．We are dealing with the results of that over-consumption in the greenest way possible，but it would be far better if we did not need to bring so much material home in the first place．
The total amount of packaging increased by 12% between 1999 and 2005．It now makes up a third of a typical household's waste in the UK．In many supermarkets nowadays food items are packaged twice with plastic and cardboard．
Too much packaging is doing serious damage to the environment．The UK，for example，is running out of areas for burying this unnecessary waste．If such packaging is burnt，it gives off greenhouse gases which go on to cause the greenhouse effect．Recycling helps，but the process itself uses energy．The solution is not to produce such items in the first place．Food waste is a serious problem，too．Too many supermarkets encourage customers to buy more than they need．However，a few of them are coming round to the idea that this cannot continue，encouraging customers to reuse their plastic bags，for example．
But this is not just about supermarkets．It is about all of us．We have learned to associate packaging with quality．We have learned to think that something unpackaged is of poor quality．This is especially true of food．But it also applies to a wide range of consumer products，which often have far more packaging than necessary．
There arc signs of hope．As more of us recycle，we are beginning to realise just how much unnecessary material we are collecting．We need to face the wastefulness of our consumer culture，but we have a mountain to climb．

51．What does the underlined phrase"that over-consumption"refer to？D
A．Using too much packaging．
B．Recycling too many wastes．
C．Making more products than necessary．

52．The author uses figures in Paragraph 2 to showD．

B．the increase of packaging recycling
C．the rapid growth of supermarkets
D．the fact of packaging overuse
53．According to the text，recyclingA．
A．helps control the greenhouse effect
B．means burning packaging for energy
C．is the solution to gas shortage
D．leads to a waste of land
54．What can be inferred from Paragraph 4？C
A．Unpackaged products are of bad quality．
B．Supermarkets care more about packaging．
C．It is improper to judge quality by packaging．
D．Other products are better packaged than food．
55．What can we learn from the last paragraph？A
A．Fighting wastefulness is difficult．

D．The author is proud of their consumer culture．

7．Taste is such a subjective matter that we don't usually conduct preference tests for food．The most you can say about anyone's preference，is that it's one person's opinion．But because the two big cola companies-Coca-Cola and Pepsi Cola are marketed so aggressively，we have wondered how big a role taste preference actually plays in brand loyalty．We set up a taste test that challenged people who identified themselves as either Coca-Cola Classic or Pepsi fans：find your brand in a blind tasting．
We invited staff volunteers who had a strong liking for either Coca-Cola Classic or Pepsi，Diet （低糖的） Coke，or Diet Pepsi．These were people who thought they'd have no trouble telling their brand from the other brand．
We eventually located 19regular cola drinkers and 27diet cola drinkers．Then we fed them four unidentified samples of cola one at a time，regular colas for the one group，diet versions for the other．We asked them to tell us whether each sample was Coke or Pepsi，then we analyzed the records statistically to compare the participants'choices with what mere guess-work could have accomplished．
Getting all four samples right was a tough test，but not too tough，we thought，for people who believed they could recognize their brand．In the end，only 7out of 19regular cola drinkers correctly identified their brand of choice in all four trials．The diet-cola drinkers did a little worse-only 7of 27identified all four samples correctly．
While both groups did better than chance would predict，nearly half the participants in each group made the wrong choice two or more times．Two people got all four samples wrong．Overall，half of the participants did about as well on the last round of tasting as on the first，so tiredness，or taste burnout，was not a factor．Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price．

28．It is implied in the first paragraph thatC．
A．the purpose of taste tests is to promote the sale of colas
B．the improvement of quality is the chief concern of the two cola companies

C．being badly damaged by fire
D．being unable to function because of excessive use

A．show that taste preference is highly subjective
B．argue that taste testing is an important marketing strategy
C．emphasize that taste and price are closely related to each other
