Recently scientists have worked out a way to judge roughly where a person has lived using strands(缕) of hair, a technique that could help track the movements of criminal suspects or unidentified bodies .
The method depends on measuring how chemical variations in drinking water show up in people’s hair.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid（列阵）falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can establish a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a frame of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.
“It’s not good for pinpointing (精确定位),” he said. “It’s good for ruling out many possibilities.”
64. What can we learn from the passage about the latest discovery?
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis identifies criminal suspects accurately.
D. The chemical composition of hair varies from person to person.
65. What does the underlined word “identical” in paragraph 3 probably mean?
A. similar B. fantastic C. beneficial D. healthy
66. What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.
The twin towns of LAUFEN/OBERNDORF
Laufen owes its former economical and cultural significance to the river Salzach,which forms a peninsula with its sharp curves（弯） there.
Laufen’s economic boom began with the salt trade and the shipping on the river.The salt—mainly coming from Hallein and Bad Reichenhall—was loaded onto bigger ships downstream,which made Laufen one of the most important ports of shipment for salt in Salzburg and Bavaria.
The archbishop（大教主） of Salzburg had given special privileges to the people who were involved in the shipping of salt on the river Salzach.
The Napoleonic Wars brought occupation and serious disturbances.They brought the sudden end to the independent state of the Duke—Archbishop of Salzburg.The end of the 18th century brought a decrease in shipping because of the general economic situation.On the 1st May 1816 Salzburg definitively became a part of Austria （Munich agreement） that’s why the Salzach became the border between Bavaria and Austria.Laufen’s suburbs Oberndorf and Altach were divided up.The number of inhabitants fell from 1392 to 809.Even the re－unification of the two towns’shipsmen’s guilds（行会） and the reorganization of 1928 could not prevent the decline of shipping which finally came to an end in the late 19th century.________played an important role in Laufen’s economy and culture life.
| A．Salt | B．Shipment | C．Guilds | D．Theriver Salzach |
The underlined word“boom”probably means________.
| A．pleasant sounds | B．sudden increase | C．sudden decrease | D．trade |
The main idea of this passage is mainly about ________.
| A．how the economy declined in Laufen |
| B．the effects of The Napoleonic Wars |
| C．how the twin towns of LAUFEN and OBERNDORF came into being |
| D．the history of Salzburg |
Vive la Tower!
Until New York’s Chrysler Building was completed in 1930,the Eiffel Tower was the tallest structure in the world.Located by the river Seine,on an avenue named after its designer,this 985－foot （300－meter） tower is the most famous edifice（大建筑物） in the city of Paris.Gustave Eiffel’s idea was certainly chosen from among 700 proposals（提议） to represent the city in the International Exhibition of Paris in 1889.It commemorated（纪念） the 100th anniversary of the French Revolution. 
In 1887,three hundred steel workers spent two years constructing the 7 000－ton tower.Yet,it was almost torn down two decades after its completion.Luckily,its antenna（天线）,used for telegraphy at the time,saved it.Last July,it looked to observers as though the tower might be destroyed after all,as ominous（不吉利的） black clouds of smoke encircled the structure.Luck was again smiling upon the tower:the fire turned out to be a small one that was quickly put out by attendants on duty.
To date,more than 200 million people have visited the Eiffel Tower.However,it has not always been a beloved tourist attraction.At first,Parisians despised it.Its architectural style and metallic composition were not considered pleasing.Today,the Eiffel Tower is adorned（装饰） with special lights that sparkle for ten minutes each hour,from sunset until one a.m.If you happen to be passing by,look up at this breathtaking monument for an astonishing sight.The Eiffel Tower,composed of iron and steel,is greater than the sum of its parts.If you wanted to see the Eiffel Tower sparkle,when might you stop by?
| A．1:15 a.m. | B．3:30 p.m. | C．9:10 p.m. | D．0:00 a.m. |
When was the Eiffel Tower almost torn down?
| A．1907. | B．1909. | C．1889. | D．2003. |
At first,what did Parisians think about the tower?
| A．The steel and iron parts were unimpressive. |
| B．The awe－inspiring design was attracting. |
| C．Both A and B are correct. |
| D．Neither A nor B is correct. |
The South Pole is a particular place on the earth.When people stand at the top of it looking around,they will find all directions face to north.No matter how they make their first step in which direction,they will always walk towards the north.That’s to say,only north and south exist there,neither east nor west exists.
At the top of the South Pole,any clock or watch keeps good time because all meridians（子午线） join there.All kinds of local time are completely suitable there.It is even difficult to distinguish（区别） New Year’s Eve from New Year’s Day.
The explorers and scientists from different countries always fix the time according to their own.Therefore the time by their watches was different when the people with different nationality gathered there.
The Winter Solstice（冬至日） is an important festival at the South Pole.It is always on June 21 or 22.This day is called Midwinter Festival,on which the daytime is the shortest in a year and the night the longest.All people at the South Pole extend greetings to each other and present gifts to each other.They usually give all kinds of celebrations.From that day on,the daytime will get longer day by day.At the top of the South Pole,your watch will ________.
| A．keep good time | B．be five minutes fast |
| C．stop | D．be ten minutes slow |
The Winter Solstice is an important festival ________.
| A．in the world | B．at the South Pole | C．at the North Pole | D．in China |
On the Winter Solstice,________ is the shortest in a year.
| A．the night | B．the noon | C．the morning | D．the daytime |
A HOUSE WITH A HISTORY
Foulsham House is a fine,stone house of the 1790s.It stands by the River Byre,in twenty－five hectares（公顷）of the best farmland in the southwest.
Smithson built the house,and the story goes back to George,the young Prince of Wales,who fell in love with the beautiful lady Kitty Wake,at one of the first Lord Foulsham’s wild woods parties.In the past many great men rode on the hills about Foulsham House,and many fine ladies took tea in the Green Room.
The house has eight bedrooms,three bathrooms,two living－rooms and a dining room with a real Adam fire－place（壁炉）.The gentleman’s library has a view over the park and the river.All rooms are light and airy（空气通畅的）,with wood,high windows,and wood floors.
At the back of the house,where the third Lord Foulsham kept the horses,there is garage－space（停车的地方）for four cars.In many other ways,this house of the 1790s meets the needs of the 2000s.

Even before World War Ⅱ ended in 1945,many world leaders dreamed of a new organization that would keep international peace and safety,and encourage international cooperation（合作）.An organization was formed.The United Nations was to work to this ideal of mankind.
When the UN was founded in 1945,it was made up of fifty members.Fifteen members sat on the Security Council（安理会）.Five members—the United States,the Soviet Union,Great Britain,France and China—were given,not changing membership on the Council.The Council was given the power to settle fights among nations by persuasion,mediation（调解） or other means.A General Assembly（联合国大会）,which included every UN member,was also set up.The Assembly could consider,discuss,and pass resolutions（决议案）.
As the UN passed its fortieth birthday in 1985,it came under increasingly sharp attack by Americans.It declared that the UN is unfit as a peace keeper and cited（援引） 130 wars since 1945 as a proof（证据）.
The UN’s supporters say that the organization is the world’s best hope for peace.The UN provides,supporters also point out,much needed economic and technical help to less developed nations.The function（功能）of the Security Council is ________.
