    1．The easy way out isn't always the easiest．I learned that lesson when I decided to treat Doug，my husband of one month，to a special meal．I glanced through my cook book and chose a menu which included homemade bread．Knowing the bread would take time，I started on it as soon as Doug left for work．As I was not experienced in cooking，I thought if a dozen was good，two dozen would be better，so I doubled everything．
    As Doug loved oranges，I also opened a can of orange and poured it all into the bowl．Soon there was a sticky dough （生面团） covered with ugly yellowish marks．Realizing I had been defeated，I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work．
    I went on preparing the rest of the meal，and，when Doug got home，we sat down to Cornish chicken with rice．He tried to enjoy the meal but seemed disturbed．Twice he got up and went outside，saying he thought he heard a noise．The third time he left，I went to the window to see what he was doing．Looking out，I saw Doug standing about three feet from the rubbish bin，holding the lid up with a stick and looking into the container．
    When I came out of the house，he dropped the stick and explained that there was something alive in our rubbish bin．Picking up the stick again，he held the lid up enough for me to see．I felt cold．But I stepped closer and looked harder．Without doubt it was my work．The hot sun had caused the dough to double in size and the fermenting yeast （酵母） made the surface shake and sigh as if it were breathing．I had to admit what the living thing was and why it was there．I didn't know who was more embarrassed by the whole thing-Doug or me．
    21．The author's purpose in writing this story isB．
    A．to show the easiest way out of a difficulty
    B．to tell an interesting experience
    C．to describe how easy it was to make bread
    D．to explain the difficulty of learning to cook from books
    22．When Doug went out the third time，the woman looked out of the window because she wasD．
    A．surprised at his being interested in the bin
    B．afraid that he would discover her secret
    C．unhappy that he didn't enjoy the meal
    D．curious to know what disturbed him
    23．What made the dough in the rubbish bin look frightening？A
    A．The shaking and sighing movement．
    B．The strange-looking appearance．
    C．A small dog inside the bin．
    D．A snake inside the bin．

    I understand why my mother is worried about my future major．I've seen my mother
    struggle to raise me on her small salary and work long hours．She leaves the house around 6：30am and usually comes home around 5pm or even 6pm．However，I want her to know that by becoming a doctor，it doesn't mean I'll be successful．I'd rather follow my dreams and create my own future．

    8．A serious problem for today's society is who should be responsible for our elderly and how to improve their Lives．It is not only a financial problem but also a quashing of the system we want for our society．I would like to suggest several possible solutions to this problem．
          First，employers should take the responsibility for their retired employees．To make this possible，a percentage of profits should be set aside for this purpose． But when a company must take life-long responsibility for its employees，it may softer from a commercial disadvantage due to higher employee costs．
    Another way of solving the problem is to return the responsibility to the individual．This means each person must save during his working years to pay for his years of retirement．This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years．This means the government might have to step in to care for the poor．
    In addition，the government could take responsibility for the care of the elderly．This could be financed through government taxes to increase the level of pensions．Furthermore，some institution should be created for senior daises，which can help provide a comfortable life for them．Unfortunately，as the present situation in our country shows，this is not a trulyviableanswer．The government can seldom afford to care for the elderly，particularly when it is busy trying to care for the young．
    One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent．
    To sum up，all these options have advantages and disadvantages．Therefore，it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations．

    46．What is the passage mainly about？C
    A．The problems faced by the old in society．
    B．Why we should take responsibility for the old．
    C．How we can improve the lives of the old．
    D．Where the old can go to get their pensions．
    47．According to the passage，how can the government help to improve the lives of retired people？D
    A．Set aside some profits to help people with problems after they retire．
    B．Increase savings levels of people during their working years．
    C．Increase the discounts for food and transport for the old．
    D．Make available pensions for those who have retired．
    48．The underlined word"viable"most probably means"B"．
    A．impossible      
    B．practical       
    C．useful          
    D．successful
    49．What can be concluded from the passage？D
    A．Taking care of the old is mainly an issue of money．
    B．Employers should allow their workers to retire at a later age．
    C．Becoming independent should be the goal of most old people．
    D．There is no single solution to the problems of the old．
    50．What is the writer's main purpose in writing this article？B
    A．To point out the need for government supped for old people．
    B．To make general readers aware of the problems of retired people．
    C．To discuss some possible solutions to an important social problem．
    D．To instruct retired people on how they can have a happier life．

    16．As demand for power and fuel grows steadily in the coming decades，we must consider every possible energy source on hand if we're to meet the world's needs．And because clean natural gas is found in great plenty，there is little doubt that it will play a major role on the world energy stage in this century，much like oil did in the last．But，like oil，gas reserves are concentrated in just a few places in the world，usually far from where they're needed most．And that's only part of the challenge．The world has had well over 100years to search for oil and to build the necessary facilities to bring it to market； the natural gas facilities，particularly when it comes to liquefied（液化）natural gas（LNG），are not nearly as developed．
    So what needs to be done？On the supply side，producing nations need policies that allow for better development of their natural gas in an open，stable business environment，not one in which the rules of the game change without warning．The governments of consuming nations，on the other hand，must make policies for sustainable（可持续的）development to ensure they'll have enough supplies in the future．That means building the related facilities，including LNG stations．This，in turn，will require coastal areas to allow these necessary，but not necessarily pretty，facilities to be built in their backyards．And energy companies have a responsibility to be good neighbors in those areas by operating these facilities responsibly and safely．They must also continue to put in the billions of dollars needed to build the complex transport and storage facilities required to bring more gas to market．
    Expanding and diversifying（使多样化）energy sources by using more natural gas could lead to lower fuel prices and to greater energy security．We've taken some of the steps to get started，but we need your help to get the rest of the way．

    41．Which of the following is TRUE according to the passage？C
    A．Gas played a major part in the 20th century．
    B．Gas reserves are widely spread around the world．
    C．Natural gas facilities are far from satisfactory．
    D．Necessary facilities are ready to bring gas to market．
    42．The underlined word"one"（in Paragraph 2）refers toD．
    A．a gas supply side                                
    B．a policy for gas development
    C．a gas consuming nation                            
    D．a business environment
    43．Consuming nations of natural gas need toA．
    A．have long-term policies for gas supply         
    B．open markets in their backyards
    C．build pretty facilities along the coast          
    D．change the rules of the game
    44．The main purpose of the passage is toD．
    A．warn people of the lack of power and fuel
    B．discuss the importance of oil and natural gas
    C．instruct people how to make use of energy sources
    D．call for better use and development of natural gas
    45．The passage might be followed by a paragraph aboutC．
    A．which countries are in great need of gas      
    B．where energy sources are concentrated
    C．what kind of help you can offer             
    D．what problems of energy sources we may face．
