Scientists warn today that the Atlantic bluefin tuna (金枪鱼) faces disappearance unless certain action
is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico
to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna
worldwide are more dangerous than anyone has imagined.
The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A
good one can fetch as much as ￡ 52,000 in the Tokyo fish markets."In my lifetime, we"ve brought this
big fish to the doorstep of death in the western Atlantic Ocean," said Barbara Block of Stanford University
in California."The electronic way of tracks provides the best scientific information we"ve ever had to
manage these tuna and we must, as an international community, start to act actively to make sure of the
future of this fish."
Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer
and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore
in search of deep ocean fish. Tuna-in the Mediterranean and Japan-have been under increasing pressure for
years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since
1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger,
eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000
in the east, no one knew whether the limits worked.
So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of
more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water
temperatures. "There are two ways to save the Atlantic bluefin tuna-protect them in their production grounds
and in their feeding grounds," Prof. Block said. "This will need immediate action in both the central Atlantic,
to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna
produce as separate populations." |

Ever since news of widespread food recalls caused by a carcinogenic dye (颜料) broke, there has been
confusion over possible links to the country of the same name, but Sudan officials say there is no connection
whatever.
Sudan 1 is a red industrial dye that has been found in some chilli powder, but was banned in food products
across the European Union (EU) in July 2003. Since the ban was put in place, EU officials have been striving
to remove some food products from the shelves. So far 580 products have been recalled. Last week Sudan"s
Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the
dye"s name.
Omaima Mahmoud Al Sharief, a press official at Sudan"s Embassy in China, explained the purpose of the
inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
"We want to keep an eye on every detail and avoid any misunderstanding there," she said."Our embassy
to Britain asked them how the dye got that name and whether the dye had something to do with our country.
But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy
last week.
"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she
said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any
explanation before we find out."
Sudan dyes, which include Sudan 1 to 4, are red dyes used for colouring solvents (溶剂), oils, waxes,
petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for
Research on Cancer. |

C. Nobody is sure of the origin of the name.
D. Many foods produced in Sudan contain the dye. |
| 3. We can infer from the passage that _____. |
A. the Sudan government is paying much attention to the food safety
B. Sudan 1 is often used to be added to the food
C. people didn"t realize the danger of Sudan 1 until 2003

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them.
More than that, though, he has also interfered (干涉) with the invisible bonds between the living things in
the forests. There are many examples of this kind of destruction. The harmfulness of man"s interference
can be seen in what happened many years ago in the forest of the Kaibab plateau (凯亚巴布高原) of
northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce.
In 1882 a visitor noted,"We, who... have wandered through its forests and parks, have come to regard it as
the most enchanting region it has ever been our privilege (特权) to visit." This was also the living place of the
Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had
mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was
forbidden. Government hunters started killing off the deer"s enemies. In 25 years" time, 6,250 mountain lions,
wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924,
there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer
was permitted again. This caused a slight decrease in the deer herd (鹿群),but a far greater loss resulted from
starvation (饥饿) and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had
dropped to 20,000 animals. By 1942 it was down to 8,000. |
| 1. The destruction of the environment of the Kaibab resulted from _____. |
A. turning the forest into cultivated land

A. a tree
B. an animal
C. a mountain
D. a game |
| 3. The number of the deer in the Kaibab had increased enormously in _____ years" time. |
A. 25
B. 6
C. 18
D. 12 |
| 4. Years later, large numbers of deer in the Kaibab died mainly because of _____. |

Many people turn to the web for health advice. Women use the Internet to look for health information
for themselves and their family significantly more than men, research has found. The study, by independent
research company Datamonitor, says that for this reason health sites should make greater efforts to appeal
to women by covering their health concerns.
The researchers, who quizzed 4,531 adults across France, Germany, Italy, Spain, the UK and the US,
found that websites have become just as important as some off-line sources of health information. Fifty-seven
percent of those who looked for health information in the past 12 months consulted Internet sources.
Report author Yvonne MacPherson said,"A distinct advantage of the Internet as a source of health
information is that information is easily accessible and can be read in private and at the leisure of the Internet
user." "Good health sites are not meant to replace interaction with a physician. Rather, they help patients
prepare for appointments and take more responsibility for their health." He added.
Currently, 32-34% of adults aged 18 to 54 used the Internet to search for health information. This number
decreases to 27% in the 55 to 64 age group, and further to 14% in the 65 and over age group. Young Internet
users often conduct online health research on behalf of older family members who do not use the Internet.
However, Datamonitor says that the audience for health information online will grow naturally as the
population ages, and more and more people grow up with the net. It recommends that website operators
focus their efforts on building a good long-term relationship with their existing consumers, rather than on
attempting to attract non-Internet users. |
| 1. What is the main subject discussed in the passage? |
A. The popularity of health websites.
B. The importance of health advice.
C. The advantage of the Internet sources.
D. The increase of people"s health concerns. |
| 2. According to Yvonne MacPherson, health information online could be described as ______. |
A. acceptable
B. convenient
C. accurate
D. abundant |
| 3. Which of the following is NOT true? |
A. Health websites should pay more attention to women"s health concerns.
B. A good health site should be able to replace interaction with a doctor.
C. The old tend to make less use of the Internet for health information.
D. The young may be the potential audience of health information online. |

At first sight, you would think the collection of hundreds of colored shards (碎片) could be a work of
abstract art. But the objects are the contents of the stomach of a sea turtle that lost its battle with plastic
pollution.
Environmentalists examined the stomach of the turtle found off the coast of Argentina. What they found
is the symptom of the increasing threat to sea turtles from a human addiction to plastic.
Sea turtles often mistake plastic items for jellyfish or other food. Ingesting (摄取) ocean pollution can
cause a digestive blockage and internal cuts. The result can be dangerous, followed by death.
Humans produce 260 million tons of plastic a year. When those products are pulled into the sea"s currents,
the plastics are just broken into smaller pieces which are consumed by marine life at the bottom of the food
chain. An examination of a green turtle found off Florida discovered that, over the course of a month, the
animal"s faeces (粪便) had contained 74 foreign objects, including "four types of balloons, different types of
hard plastic, a piece of carpet-like material and two 2-4 mm tar balls."
"The oceans have become on giant refuse bin for all manner of plastics. All sea turtle species may be
seriously harmed," according to the biologists Colette Wabnitz, from the University of British Columbia."The
symptom of this growing crisis can be seen inside and on sea turtles as well as their oceanic and terrestrial
habitats. It is urgently necessary to directly confront the source of plastic pollution, redesign packaging and
rethink the very idea of "throwaway culture"."
Almost all marine species, from plankton to whales, have ingested plastic. But, even in small quantities,
plastic can kill sea turtles, the biologists said.
Fifty out of 92 turtles found dead, stranded on the shorelines of Rio Grande do Sul state in Brazil, had
ingested a"considerable amount of man-made debris". |
| 1. What"s the passage mainly about? |
A. How to prevent the sea turtle from plastic.
B. Why plastic is dangerous to the sea turtle.
C. Sea turtles suffering from plastic pollution.
D. Protecting the sea turtle from being polluted. |
| 2. The author mentions the "throwaway culture" probably in a(n) ______ tone. |
A. praising
B. positive
C. comedic
D. ironic |
| 3. The underlined word in the last paragraph probably means _____. |
A. a kind of food
B. a kind of fish
C. pieces of rubbish
D. pieces of cloth |
| 4. The paragraph following the last one will probably talk about ______. |
A. the way the biologists examined the sea turtle
B. some tips on how to make sea turtles avoid plastic
C. how to prevent plastic pollution
D. the reason why we should protect the sea turtle |
