听力原文： Back in those primitive times it was unnecessary to have a special form. of exchange value for everything, like a price. In thee times the only things that were really valuable were the skills to sat vive. But as society became more complex, people depend more on others who were living far away; then it became important for people to develop some method for exchanging value without having to ex change the actual goods.
This need to develop a method for exchanging value was what led to the use of money. Money was a means of exchanging value without having to actually exchange the specific things you wanted. Before the use of money, people had to trade things with each other, and it was usually very difficult to decide what everything was worth in relation to each other. If you had three animals skins and your friend had two pots of dried betas, how did you know how many skins were equivalent to a pet of beans if they didn't have a price？ With the introduction of money, all things could begin to hate a common value that everybody could know about. This led to a standardized set of values among people. As the power of money increased, values that were different from the majority were no longer recognized. The value of something in terms of money became the ultimate value. In order for money to function, the whole society has to agree on the same values.

Task 1
Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.
College is a place to explore many possibilities; you really can't do it all—unless you manage your time wisely. Here are some tips I have found very helpful for managing my time and maximizing my study efforts:
1. Determine your goals. What do you want to get out of a college education？ Academic （学术的）knowledge？ Leadership experiences within a club？ Decide what is most important to you.Then devote proportionate (成比例的) amounts of time to those efforts.
2. Plan ahead.You may think you can keep everything in your head,but as the activities on your schedule start piling up, making a schedule can really help organize even little tasks.
3. Study at strategic (关键的) times.Don't wait until you're falling asleep to study.Study first.Save those e-mails to check later, because tasks that don't require much energy and attention can still be done when you're tired.
4. Motivate (激励) yourself! You know that TV show you've been dying to see, or that game of chess you've been waiting all week to challenge your friend to. These and many other special activities can be used for motivation. Promise yourself that you'll finish your biology assignment before you go off and "play". That way, you'll force yourself to work efficiently.(Don't rush through the assignment, though.)
5. Take a nap. Sometimes even a 20-minute nap in the afternoon will give you the extra energy you need to get through the day.
We need to plan ahead in order to________.
A．keep a record of all the events
B．better organize our activities
C．store everything in our head
D．pile up little tasks neatly

Wildfires
In just seconds, a spark or even the sun's heat alone sets off an extremely large fire. The wildfire quickly spreads, consuming the thick, dried-out plants and almost everything else in its path. What was once a forest becomes a virtual powder keg of untapped fuel. In a seemingly instantaneous burst, the wildfire overtakes thousands of acres of surrounding land, threatening the homes and lives of many in the vicinity.
Fire Starters
On a hot summer day, when drought conditions peak, something as small as a spark from a train car's wheel striking the track can ignite a raging wildfire. Sometimes, fires occur naturally, ignited by heat from the sun or a lightning strike. However, the majority of Wildfires are the result of human carelessness.
Common causes for wildfires include:
Arson
Campfires
Discarding lit cigarettes
Improperly burning debris
Playing with matches or fireworks
Prescribed fires
Everything has a temperature at which it will burst into flames. This temperature is called a material's flash point. Wood's flash point is 572 degrees Fahrenheit(300 ℃). When wood is heated to this temperature, it releases hydrocarbon gases that mix with oxygen in the air, combust and create fire.
There are three components needed for ignition and combustion to occur. A fire requires fuel to burn, air to supply oxygen, and a heat source to bring the fuel Up to ignition temperature. Heat, oxygen and fuel form. the fire triangle. Firefighters often talk about the fire triangle when they are trying to put out a blaze. The idea is that if they can take away any one of the pillars of the triangle, they can control and ultimately extinguish the fire.
After combustion occurs and a fire begins to burn, there are several factors that determine how the fire spreads. These three factors include fuel, weather and topography. Depending on these factors, a fire can quickly fizzle or turn into a raging blaze that scorches thousands of acres.
Fueling the Flames
Wildfires spread based on the type and quantity of fuel that surrounds it. Fuel can include everything from trees, underbrush and dry grassy fields to homes. The amount of flammable material that surrounds a fire is referred to as the fuel load. Fuel load is measured by the amount of available fuel per unit area, usually tons per acre.
A small fuel load will cause a fire to burn and spread slowly, with a low intensity. If there is a lot of fuel, the fire will burn more intensely, causing it to spread faster. The faster it heats up the material around it, the faster those materials can ignite. The dryness of the fuel can also affect the behavior. of the fire. When the fuel is very dry, it is consumed much faster and creates a fire that is much more difficult to contain.
Here are the basic fuel characteristics that decide how it affects a fire:
Size and shape
Arrangement
Moisture content
Small fuel materials, also called flashy fuels, such as dry grass, pine needles, dry leaves, twigs and other dead brush, burn faster than large logs or stumps(this is why you start a fire with kindling rather than logs). On a chemical level, different fuel materials take longer to ignite than others. But in a wildfire, where most of the fuel is made of the same sort of material, the main variable in ignition time is the ratio of the fuel's total surface area to its volume. Since a twig's surface area is much larger than its volume, it ignites quickly. By comparison, a tree's surface area is much smaller than its volume, so it needs more time to heat up before it ignites.
As the fire progresses, it dries out the material just beyond it—heat and smoke approaching potential fuel causes the fuel's moisture to

The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations. But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents' son. In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two rapes and murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples(样本). The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person's privacy. That includes a person's medical history, racial origin or psychological profile. "There is the long-term risk that people can get into these samples and start getting additional information about a person's paternity or risk of disease," Jeffrey said.
DNA testing is not an unfailing proof of identity. Till, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey's estimates(估计) the probability of two individuals' DNA profiles matching in the most commonly used tests at between one in a billion or one in a trillion.
The passage is mainly about ______.
A．the discovery of fingerprinting by Jeffery
B．the practice of fingerprinting in court
C．the fingerprinting in the present situation
D．the merits and demerits of fingerprinting

New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it's up to consumers to decide whether the new fat-free products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can't be digested at all.
Normally, special chemicals in the intestines(肠)"grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatting acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broke down. Manufacturers say it's the ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular at without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E and K from being absorbed. It can also prevent the absorption of carotenoids(类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.
We learn from the passage that olestra is a substance that______.
A．contains plenty of nutrients
B．renders foods calorie-free while retaining their vitamins
C．makes foods easily digestible
D．makes foods fat-free while keeping them delicious
