In the atmosphere , carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping.

   According to a weather expert’s prediction, the atmosphere will be 3 ℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球), possibly resulting in an alteration of the earth’s chief food growing zones.

   In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.

   Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth

   However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude, therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?

   One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot sports and ‘cold” spots( that is, the relatively less hot spots) on the sun. As the sun rotates(使旋轉(zhuǎn)), every 27.5 days, it presents hotter or colder faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth’s atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.

   Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is hot. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(慣性) of the earth’s climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun’s fading heat.

It can be concluded that concentration of carbon dioxide in the atmosphere would ____.

A. mean a warming-up in the Arctic.              

B. raise the temperature of the earth’s surface.

C. prevent the sun’s rays from reaching the earth’ s surface.

D. explain the cause of great changes in the climate in the northern hemisphere.

The article was written to explain____.

A. the greenhouse effect.          B. the solar effects on the earth.

C. the causes affecting weather.     D. the models of solar weather of solar weather interactions.

Although the fuel consumption is greater in the northern hemisphere, temperature there seems to be falling. This is ____.

A. mainly because the levels of carbon dioxide are rising

B. partly due to changes in the output of solar energy

C. possibly because the ice caps in the poles are melting

D. only due to the effect of the inertia of the earth’s climate

On the basis of their models, scientists are of the opinion that     .

A. the climate of the world should be becoming cooler

B. the new Ice Age will be delayed by the greenhouse effect

C. the man-made warning effect helps to increase the solar effects

D. it will take thousands of years for the interia of the earth’s climate to take effect.

If the assumption about the delay of a new Ice Age is correct, ___.

A. ice would soon cover the northern hemisphere.

B. the greenhouse effect could work in favor of the earth.

C. the best way to overcome the cooling effect would be to burn more fuels.

D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly.

       [1]World Consumer Rights Day is celebrated annually by consumer organizations worldwide. It commemorates the historic declaration on March 15, 1962 by John F. Kennedy, the former U.S. President, of the basic Rights of consumers, which include: "the right to safety", "the right to be informed", "the right to choose", and "the right to be heard".  

[2]This declaration has led to international recognition by governments and the United Nations that all citizens, regardless of their incomes or social standing, have certain basic Rights as consumers. Officially, World Consumer Rights Day was first observed on March 15，1983 and has since become an important occasion for mobilizing citizen action, with recognition of consumer rights taking off around the world. On April 9，1985, the United Nations Assembly General Assembly adopted the UN Guidelines for Consumer Protection that provide a framework for strengthening national consumer protection policies around the world.  

[3]The guidelines included Kennedy's four basic consumer rights plus another four: the right to satisfaction of basic needs; the right to redress(賠償); the right to education; and the right to a healthy environment. Currently, the fundamental consumer rights are recognized globally.

[4]World Consumer Rights Day normally has a theme associated with an activity or development that is relevant to consumers. Whatever their objectives, they share the same underlying aim of bringing about important and needed benefits for consumers.  

   [5]In recent years, progress has been made for recognition and protection of consumer rights in developing countries. At least, March 15 is a day when consumers are filled with pride and satisfaction. However, there are many reports on violation of consumer rights by unethical marketing practices.

   Reading about history is nice, but finding ties to long-ago historical events in your own backyard is really exciting．

   In their heavily populated area, neighbors Adam Giles,13, and Derek Hann．12, uncovered pieces of glass that looked quite different from what’s used today．“After digging about two feet down, I came across an interesting bottle,” Derek said．The bottle had a “pontil scar” on the bottle, an indication that it was hand-blown rather than machine made．It also had the name “Fraser” on one side．

   Adam found remains of a green bottle and some very thick brown glass—again, far different from today’s．

   After doing research on the computer, the boys contacted Aimee Wells of the county’s Cultural Resources office．She showed them a computer program that digitally puts old maps over modern satellite photographs．

   Bingo! Their back yards were once part of a military（軍事的） encampment（營(yíng)地） called Camp Alger used by Ohio soldiers on their way to fight in the Spanish-American War in 1898．

   So how do a few bottles get connected to a brief war that was more than a century ago? “We get there by good judgment,” Wells said．“We know the time period of the bottles and what happened in that area．” Anyone can dig a hole, but archaeologists seek a deeper understanding．How do objects found relate to things around them?

   When Derek and Adam realized that a solider might have held that Fraser bottle 110 years ago, they wondered what he might have been thinking．What did he see as he looked around him? How did he pass the time waiting to go into battle?

   Historical records show that while waiting for orders, the soldiers in and around Camp Alger played baseball, played instruments and walked seven miles to the Potomac River once a week for baths．A spread of strange fever forced the closing of the camp, and there are no buildings to study．“What’s left is only what’s in the ground,” said Wells．

   Derek’s and Adam’s back yards have joined the 3,400 places listed on the county’s register of archaeological sites．The boys were given tips on how to dig effectively and safely, and on how to document the location of items found．

   The official record of their finds serves as another piece of the puzzle for historians seeking to form a more complete story of what happened．

   “Not everyone is going to have historical objects in their own yard,” Wells said．“That’s okay．Make your own time capsule and bury it．What would you want people to know about your life years from now?”

63．What is the passage mainly about?

       A．How Adam Giles and Derek Hann dug out the remains of an ancient military encampment．

       B．What Adam Giles and Derek Hann found in their back yard and its relationship with an encampment．

       C．The great contribution Adam Giles and Derek Hann made to the cause of archaeology．

       D．The tips on how to dig out ancient objects buried under the ground safely and effectively．

64．From the passage, we can see that the boy’s discovery _______．

       A．includes all kinds of hand-made and machine- made glass．

       B．has helped historians find out what happened in 1898．

       C．couldn’t have been meaningful without Aimee Wells’ help．

       D．has added the county to the list of archaeologist sites．

65．When Wells said “We get there by good judgment．” （Paragraph 6）, she meant that_______．

       A．they have established the ties to Camp Alger by finding out the time period of the bottles．

       B．they have figured out how to get to the place where the brief war happened．

       C．they have managed to dig out the bottles in the back yard safely with common sense．

       D．they were able to locate the soldiers who used the Fraser bottles 110 years ago．

66．Which of the following fits the description of historical records?

       A．The soldiers in and around Camp Alger delighted in playing basketball in their spare time．

       B．When Camp Alger was forced to close, all the buildings there were destroyed．

       C．The soldiers in and around Camp Alger often buried some bottles underground as time capsules．

       D．Camp Alger was forced to close because of a spread of a strange fever．

 29．Internet，as well as newspapers and magazines，____an inportant part in our daily life．

    A． have played    B．a(chǎn)re playing

C． is playing      D．has been played

9、The number of people invited ______ fifty, but a number of them _____ absent for different

reasons.

A.were, was    B. was, was    C. was, were    D. were, were

65. The boy was lucky enough ________.

A. to escape to be punished   B. escaping to be punished

C. to escape being punished   D. to escape punishing
