Today, among people everywhere, there is an increasing awareness and worry about the steady growth in the world’s population．A recent survey conducted by the United Nations Fund for Population Activities （UNFPA） reported that this growth will continue until the end of the next century．For developing countries alone, the annual average population growth is, at present, 4．6% compared to 2．0% for developed countries．At this rate, the world’s population will reach 10．2 billion by the turn of the 21st century．With the growth in population is the problem of food security… the guarantee of a steady supply of food．The unstoppable growth in population justifies the Malthusian Doctrine that population of a region will continue to grow unless checked, and this is of course alarming since it will inevitably lead to food shortages of considerable proportions．
Our forests are an abundant source of food and fuel, two items essential in sustaining life．Above 30% of the world’s land surface is covered by such forests．In Asia alone, more than two billion people depend heavily on forest products for their subsistence and survival．To maintain a reasonable balance between population growth and food supply, this natural source of life — sustaining food and fuel must be conserved and protected from its worst enemy — man himself．It is appalling （令人震惊的） to note that in many developing countries, which are themselves heavily hit by population-food imbalance, governments approve the cutting down of forests to meet their immediate needs for saleable timber, and also for agricultural land．Often the cutting down and burning of forests is conducted with total abandon owing to the absence of sound forestry techniques and management．At the rate tropical forests are now being cleared each year, the world’s tropical forests will be completely destroyed within the next 100 years．
In order to maintain food security for the world’s population, the Food and Agricultural Organization of the United Nations （FAO） has launched a campaign aimed at ensuring food supply, maximizing stability in the flow of this supply and ensuring access to it by all．Forestry, according to the FAO, plays a vital role in making it possible to fulfill all its three objectives．Its most important role is that of conserving soil and water．Trees provide natural protection against soil erosion （侵蚀） by absorbing the excess water brought by heavy rains．
1．The first paragraph tells us that ____．
A．the flow of food supply is the result of population increase．
B．the world population has reached the 10-billion mark．
C．the problem of population growth has caused considerable alarm in a few countries．

A．an optimistic view of the future B．a pessimistic outlook for the future
C．an encouraging picture D．an indifferent picture
3．In this context, “this natural source of life — sustaining food and fuel” （in Paragraph 2） refers to ____．
A．the flow of food supply B．forests
C．woodland products D．man’s worst enemy
4．The three objectives of the FAO can be replaced by ____．
A．stopping population growth B．increasing food production
C．achieving food security D．ensuring maximum utilization of forests
SHANGHAI: The Transportation Information System for 2010 Shanghai World Expo has been completed and put into trial operation, officials said yesterday．

Option 1: Official site for Expo traffic information
Inspired by Aichi Expo and the Beijing Olympic Games, the Shanghai event will also launch its official website of traffic information, www．jtcx．sh．cn．Mobile phone users can log on to www．jtcx．sh．cn/m．The website delivers daily traffic information as well as travel guide around Expo garden, and advocate using public transport during the event．
Option 2: Expo Transportation guide
Two portable travel guides were produced for the convenience of tourists in the Yangtze River Delta．
One mainly targets visitors from the 19 prefecture-level cities of the Yangtze River Delta．The map introduces information of intercity coach lines, car parks, subway transfers．It will be distributed free at highway tolls and is also available for download on the website．
The other one focuses on visitors in Shanghai．The map will detail the various entries leading to the Expo site, as well as bus stops and subway stations around the city．The introduction of over 90 bus lines connecting the Expo garden to the rest of the city will also be listed．The map will be available at hotels, railway stations, airports and residential areas．
Option 3: Radio and television broadcasts
Visitors can also get updated traffic information at home or on their mobile devices as the Shanghai Traffic information center will broadcast live traffic condition via radio and TV during the event, so that travelers can adjust their travel plan accordingly．

If radio and television broadcasts can not meet your needs of traffic information, organizers in Shanghai have also set up a special hotline for Expo traffic enquiries．There will be two hotline numbers 962010 and 12319 at your service twenty-four hours．
Option 5: Variable message signs
For drivers the variable message signs will become the first choice to access to traffic information．During the Expo, the signs will play an important role in helping drivers to receive traffic flow, speed, models and other information, as well as traffic incidents and road closure information, so as to avoid congestion．
Option 6: Mobile phone browsers and taxi terminals
Visitors can obtain real-time traffic conditions via mobile phone browsers．Traffic information will also be provided to car mounted terminals on the 4,000 Expo taxis, which will enable drivers to have timely access to real-time status on roads．

When I was an education official in Palo Alto, California．Polly Tyner, the president of our school board, wrote a letter that was printed in the Palo Alto Times．Polly’s son, Jim, had great difficulty in school．He was classified as educationally disabled and required a great deal of patience on the part of his parents and teachers．But Jim was a happy kid with a great smile that lit up the room．His parents acknowledged his academic difficulties, but always tried to help him see his strengths so that he could walk with pride．Shortly after Jim finished high school, he was killed in a motorcycle accident．After his death, his mother submitted this letter to the newspaper．
Today we buried our 20-year-old son．He was killed instantly in a motorcycle accident on Friday night．How I wish I had known when I talked to him last that it would be the last time．If I had only known I would have said, “Jim, I love you and I’m very proud of you．”
I would have taken the time to count the many blessings he brought to the lives of the many who loved him．I would have taken the time to appreciate his beautiful smile, the sound of his laughter, his genuine love of people．
When you put all the good qualities on the scale and try to balance all the irritating phenomena such as the radio which was always too loud, the haircut that wasn’t to our liking, the dirty socks under the bed, etc．, your angry feelings won’t amount to much．
I won’t get another chance to tell my son all that I would have wanted him to hear, but, other parents, you do have a chance．Tell your young people what you would want them to hear if you knew it would be your last conversation．The last time I talked to Jim was the day he died．He called me to say, “Hi, Mom! I just called to say I love you．Got to go to work．Bye．” He gave me something to treasure forever．
If there is any purpose at all for Jim’s death, maybe it is to make others appreciate more of life and to have people, especially family members, take the time to let each other know just how much we care．
