Choose the most suitable heading from this list for each paragraph of the passage．Note that there is one extra heading．
A．Illegal hunting has caused a decrease in the number of sea turtles．
B．Most turtles are eaten by Mexicans and Mexican Americans．
C．A campaign to protect sea turtles．
D．Many sea turtles are killed because people eat turtle meat during a religious observance．
E．Government should prevent sea turtle hunting to increase the number of the species．
F．A letter was written to Pope to save endangered sea turtles．
(1)
Environmental groups in the United States are leading a campaign to save thousands of endangered sea turtles．They have asked Pope John Paul the Second to ban turtle meat during the Christian religious observance known as Lent．Christians observe Lent in preparation for the holiday of Easter．
(2)
Environmental groups say illegal turtle hunting is one of the major threats to endangered sea turtles in southern California and Mexico．It has been illegal to harvest and eat sea turtle meat in Mexico for more than ten years．However, demand for sea turtle meat is widespread in both Southern California and Mexico．Biologists believe that illegal hunting is one of the main reasons for the sharp drop in sea turtle populations during the past thirty years．
(3)
The week before Easter Sunday is an especially deadly time for the turtles．As many as 5000 turtles are killed during this time each year．Many Mexicans and Mexican Americans eat turtle meat during the days before Easter．Many people do not eat meat during this holy time in order to obey the rules of Lent．Because sea turtles swim, many people consider them to be fish．Fish is permitted during Lent．
(4)
The Sea Turtle Conservation Network is a union of fishermen, environmental activists and researchers．They sent a letter to Pope John Paul, urging the Roman Catholic Church leader to officially declare that sea turtle flesh is meat, not fish or seafood．They say thousands of these endangered animals would be saved if people did not eat them during this religious period．The letter also asked members of the Catholic Church to obey laws banning the capture of turtles in Mexico and the United States．
(5)
About 35 000 endangered sea turtles are killed near the coasts of Baja, California each year．Studies have shown a sharp drop in the numbers of females．They travel from as far away as Japan to lay their eggs on local beaches．Environmental activists say hunting sea turtles for their meat is the main barrier to the recovery of the species．They have urged the governments of the United States and Mexico to improve enforcement of the ban on sea turtle harvesting．
B
Energy-saving Finns invented the first ice skate more than 5,000 years ago, as a practical method of transport to make getting across frozen lakes less of a struggle.
The earliest skates would have been blades made from bones and are one of the oldest means of transport ever discovered —they may even have been essential survival tools.
Researchers at Manchester Metropolitan University have calculated that ice skates would have saved energy by 10 percent, and suggest that they were developed for practical use and were not used for recreation, as they are today.
They think the most likely birthplace of skating is southern Finland, where there are many icy lakes.
The scientists have put their theory to the test and made replica（复制品） skates modeled after examples held at the British Museum and the Fitzwilliam Museum in Cambridge.
Volunteers on ice rinks in the Alps had their heart rates, oxygen intake and skating speeds measured while they skated with the replica skates. From this experiment, re-searchers were able to calculate energy consumption and the efficiency of their skating. They discovered that skating over the land in ancient Fin-land would have saved 10 percent of people’s energy. The result is based on the fact that Finland has the highest concentration of lakes in the world. The ancient Finnish people could benefit more than others from developing this tool for transport.
In a time and environment in which the balance between energy taken from food and energy required to live was crucial; the least cost of energy might have helped humans survive in extreme conditions.
45. The first ice skate invented by the Finns was used for _____.
A. recreation B. transportation across lakes
C. saving energy D. sports
46. The birthplace of skating might be southern Finland because _____.
A. there are many icy lakes there
B. people need more oxygen to breathe in there
C. people feel tired easily there
D. transportation there is more difficult
47. Scientists have experimented with replica skates and found that with those skates the ancient
Finnish people would have _____.
A. crossed a lot of lakes
B. saved 10 percent of energy when crossing the lakes
C. climbed the Alps easily
D. otherwise wasted a lot of food and energy
48. It can be inferred from the story that _____.
A. the Finnish people were clever enough to invent the practical skates
B. there were a lot of lakes in ancient Finland
C. the living conditions were very hard for the ancient Finnish people
D. it was very cold in ancient times in Finland
