      Every year, World Blood Day is celebrated by blood services worldwide on 14 June, the birthday
of Nobel Prize winner Karl Landsteiner, the man who discovered the ABO blood group system. If you
have every thought of becoming a blood donor, just register to do it. And you should never worry about
the donation.
     Just under a pint (around 470ml) of blood is taken at one sitting. This amount is no more than 13
percent of your total blood volume, and is quickly replaced by your body.
     It may come as a surprise, but whole blood is only rarely used. Different blood components are used
to treat a range of conditions. None goes to waste. Red blood cells are frequently used to replace heavy
blood loss after an accident, surgery or childbirth. White blood cells and antibodies (抗體) are used to
help people fight infections if their immune system doesn't appear to be responding to antibiotics (抗生
素). Plasma (血漿), the straw-coloured fluid which carries the blood cells and contains proteins, are
used to treat burned patients.
     First-time donors should be aged between 17 and 65, weigh at least 50kg and be in good health. If
you have donated before, you can start being a donor again up to your 70th birthday.
     Although most people are able to give blood, some people who pose health risks or are at a higher
risk of having come into contact with an infectious disease are no tasked to be donors. Pregnant women
or those who have had a baby in the last 9 months should not donate blood.
     Blood has a very short shelf life. Some blood components can be kept longer than others, for instance
red blood cells will keep for 35 days but platelets(血小板)for only five. Remember, you should wait at
least 16 weeks before donating blood again.

1. People should never worry about the donation mainly because _____.

A. it causes no pain to their body
B. being a blood donor is a great honor
C. their bodies can produce new blood soon
D. people have a mature research on it

2. What component of blood is used to treat burned patients?

A. Plasma
B. Red blood cell
C. Antibody
D. White blood cell

3. We can learn from the passage that _____.

A. whole blood is most widely used in hospital
B. platelets can be kept for more than 10 days
C. people can donate their blood four times a years
D. people can donate at most 470 ml of blood each time

4. Who can donate their blood?

A. A teenager who is studying in a primary school
B. A mother who is about to give birth to a new baby
C. An adult who smokes and drinks from time to time
D. A man just coming back for a place suffering from malaria

5. What is the purpose of the author in writing this passage?

A. To teach people how to be a blood donor
B. To give people the knowledge of blood donation
C. To advise people to benefit from blood donation
D. To remind people of the importance of blood donation

Oldest Ever Galaxy Found

　　WASHINGTON(AP)－Astronomers believe they’ve found the oldest thing they’ve ever seen in the universe：It’s a galaxy(星系)far, far away from a time long, long ago．

　　Hidden in a Hubble Space Telescope photo released earlier this year is a small point of light that European astronomers now calculate is a galaxy from 13．1 billion years ago．That’s a time when the universe was very young, just about 600 million years old．That would make it the earliest and most distant galaxy seen so far．

　　By now the galaxy is so ancient it probably doesn’t exist in its earlier form and has already changed into bigger neighbors, said Matthew Lehnert of the Paris Observatory, lead author of the study published online Wednesday in the journal Nature．

　　“We are looking at the universe when it was a 20th of its current age,” said California Institute of Technology astronomy professor Richard Ellis, who wasn’t part of the discovery team．“In human terms, we’re looking at a 4-year-old boy in the lifetime of an adult．”

　　While Ellis finds the basis for the study “pretty good”, there have been other claims about the age of distant space objects that have not held up to careful examination．And some experts have questions about this one．But even the doubters praised the study as important and interesting．

　　The European astronomers calculated the age after 16 hours of observations from a telescope in Chile that looked at light signatures of cooling hydrogen gas．

　　Earlier this year, astronomers had made a general estimate of 600 to 800 million years after the Big Bang(宇宙大爆炸)for the most distant unclear points of light in the Hubble photograph, which was presented at an astronomy meeting back in January．

　　In the new study, researchers focused on a single galaxy in their analysis of hydrogen’s light signature, further finding out the age．Garth Illingworth of the University of California, Santa Cruz, who was the scientist behind the Hubble image, said it provided confirmation for the age using a different method, something he called amazing “for such faint objects”．

(1)

[　　]
A．	the universe came into being about 14 billion years ago
B．	the galaxy is believed to be the same as it was just born
C．	the newly-discovered galaxy is the oldest one in the universe

[　　]
A．	the universe is actually very young
B．	the life-time of the universe is surprisingly long
C．	the humans have been so able as to see far into the universe
D．	what we can see about the universe now is just the tip of the iceberg

(3)

    Ever since news of widespread food recalls caused by a carcinogenic dye(顏料) 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(溶劑), oils,
waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International
Agency for Research on Cancer.

1. What does the underlined word mean in paragraph one?

A. Causing cancer.
B. Having side effect.
C. Containing poison.
D. Poisonous.

2. How did the Sudan 1 get its name?

A. The dye is often produced in Sudan.
B. The dye has something to do with the country named Sudan.
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
D. many food shops will be closed down

4. Which of the following is the best title?

A. Keep away from Sudan 1
B. No Sudan 1 dye links to the country
C. How Sudan 1 dye got its name?
D. Pay attention to the food safety

     Ever since they were first put on the market in the early 1990s, genetically modified (GM, 轉基因) foods
have been increasingly developed and marketed in many countries in the word, mainly on the basis of their
promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it
would, is it the best solution?
     Despite what it promises, GM technology actually has not increased the production potential of any corp.
In fact, studies show that the most crown GM crop.
     GM soybeans, has suffered reduced productivity. For instance, a report than analyzed nearly two decades
of research on major GM food crops shows that GM engineering has failed to significantly increase US crop
production.
     Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers
that they will make good profits by saving money on pesticides (殺蟲劑). On the contrary, US government
data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional
crops. "The promise was that you could use less chemicals and boost production. But neither is true," said Bill
Christenson, President of the US National Farm Coalition.
     At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more
than enough food in the world and that the hunger crisis is not caused by production, but by problems in food
distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results
from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
     As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that
GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are
available, among which "green" farming is supposed to be the first choice.

1. The author develops the second paragraph mainly _____.

A. by classification
B. by comparison
C. by example
D. by process

2. What does the underlined word "boost" in the third paragraph probably mean?

A. Control.
B. Evaluate.
C. Obtain.
D. Increase.

3. GM companies promise farmers that they will benefit from ______.

A. practicing "green" farming
B. use of less chemicals
C. fair distribution of their crops
D. using more crops for fuel

4. Which of the following best describes the attitude of the author towards GM technology?

A. Optimistic
B. Defensive
C. Disapproving
D. Casual

     Ever felt like destroying the car in front of you when you're
stuck in an endless traffic jam?
     Well ,the Spanish company StopStress is offering clients(客戶 )
the possibility of doing just that-but in controlled ,safe conditions.
     Clients can also destroy computers, mobile phones and TV sets
in what the company calls" destructible therapy" ( therapy : treatment
of a medical disorder).
     "We target the machines that cause the most stress in modern
life,"company co-founder Jorge Arribas said in a telephone inter-
view. "People get rid of stress by screaming and beating the ma-
chines until they are tired out. "he explained.
     The company, based in the northern Spanish city of Soria, uses
deserted cars that still work. Heavy-metal music is used to excite
the clients. They are given protective suits and glasses, helmets and
huge hammers.
     Most people's rage only lasts for 5 to 10 minutes. But some go
on for hours : they beat cars on which they've put the names of people
or ideas they would like to get rid of.
     "Some even get together to turn the car over, "Arribas says. A
session costs 60 euros(US $80)per person.
     Arribas says the idea came to him when he was having trouble
parking his car.
     "Dozens of people have used the therapy, which helps people
become aware of their stress level and helps them to slow down,"
Arribas explained.
     "It's better to channel violence in a controlled way than to get
it out on one's husband and wife or in a traffic jam. "he added.
     StopStress already has branches in three Spanish cities, and is
planning to extend its market beyond Spain's borders.

1. The Spanish company StopStress offers people the chance to_______.
