Medicine comes in lots of different packages. Painkillers in a tablet can make your headache go away. Antibiotic cream (抗菌素膏) from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?
A team of scientists from Scotland say “yes”. They’ve engineered special chickens that lay eggs with disease-treating drugs inside.
These eggs come from chickens that have been engineered to produce certain drugs inside their egg whites.
These drugs are made of molecules called proteins(蛋白质). Animals make thousands of proteins — they’re the main element in skin, hair, milk and meat. Since animals can make proteins easily, they’re good candidates (候选者) for making protein drugs.
Researchers have already made cows, sheep and goats produce protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. Those qualities could make chickens a better choice to become living drug factories, says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA — the code that tells cells how to make proteins — so that the birds’ cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis (多发性硬化).
The scientists changed the chickens’ DNA so that the birds made these drugs only in their egg whites. This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs.
If you cut your finger, you may use ________ to cure it.

A．painkillers in a tablet	B．antibiotic cream from a tube
C．chicken eggs	D．protein drugs

Which of the following statements is NOT true?

A．Scientists from Scotland have succeeded in packing medicine into chicken eggs.

B．The drugs are made of molecules called proteins.

C．Scientists chose chickens for their experiments because chicken eggs taste delicious.

D．The animals are good candidates for making protein drugs.

The drugs in special chicken eggs can ________.

A．treat lung cancer	B．help reduce headache
C．change people’s DNA	D．treat multiple sclerosis

We can infer from the passage that ________.

A．eating eggs is the best choice for the patients now

B．scientists changed the chicken’s DNA and put all the drugs in chicken eggs

C．we may eat special eggs as drugs when we are sick in the future

D．the drugs produce harmful effects on the chicken’s bodies

The best title for the passage is ________.

A．Chicken Eggs to Replace Medicine	B．Chicken Eggs as Drug
C．Chicken Eggs and Medicine	D．Chicken Eggs and Animal Milk

Eleven-year-old Evan Green doesn’t want to save just one tree－he wants to save a whole rainforest!
In the Redwood City, Calif., a boy started a group called the Red Dragon Conservation Team four years ago to do just that. So far, the team’s members have raised $4,500. That’s enough to purchase and protect more than 16 acres of rainforest in Costa Rica through the Center for Ecosystem survival.
Every year, thousands of square miles of rainforest are destroyed worldwide. Logging（伐木）and farming are mostly likely to blame, scientists say. The loss is terrible news for animals and people. Even though rainforests cover less than 2 percent of the earth, they are home to half the world’s plants and animals. Rainforests also provide water and help control the earth’s climate.
Evan’s work to save the rainforests recently earned him a Barron prize for Young Heroes. The prizes are given to children or teenagers who have made a positive difference in the world. Evan’s goal is “to save enough rainforests to last forever”. He won’t have to do it alone. His actions have already inspired other kids to chip in. One girl asked for donations instead of presents on her birthday. She raised $850. Other kids are starting their own conservation teams.
Evan says everyone can help the planet－even by taking small steps such as recycling. He and his family try to make a difference every day. “We recycle, we try to limit our garbage… we’ve been walking a little more, and we buy local food,” Evan said.
48. How much does it cost to buy and protect an acre of rainforest in Costa Rica?
A. About $4,500.      B. About $850.     C. About $280.     D. About $1,000.
49. The underlined phrase “chip in” in Paragraph 4 probably means “________”.
A. look at                                    B. contribute money
C. ask for birthday presents               D. donate gifts
50. What Evan said in the last paragraph suggests that _________.
A. we can all do something to protect the earth
B. actions speak louder than words
C. we should learn to recycle from now on
51. What would be the best title for the passage?
A. Evan Green-a famous teenager    B. The Red Dragon Conservation Team
C. Rainforests are being destroyed    D. Boy gathers support for rainforests

第三部分阅读理解（共两节，有16小题，满分32分）
第一节：阅读下面短文并做每篇后面的题目。从A、B、C、D四个选项中，选出能回答所提问题或完成所给句子的最佳答案。（本节有11小题；每小题2分，共22分）
A quarrel at home may result in you falling ill. Don’t laugh, it’s true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say.
Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma. It is because she is suffering from depression (抑郁症), caused by bad relations at home, doctors explained.
“We don’t get sick or stay well by ourselves,” says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research.
The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected may double. But effects on health are not only written in our DNA.
Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too.
Ferrer’s research also found that if teenagers feel they are ignored or unimportant at home they are more likely to get sick.
We may never fully understand all the effects that families have on our health. But just as individual (个别的) problems can have effects on others, a small improvement can have big benefits, Ferrer said.
45. Which of the following can best explain why Wang Xiaoyu fainted in class?
A. Because her classmates often quarreled in class.
B. Because her parents used to quarrel.
C. Because of her depression caused by bad family relations.
D. Because her classmates shouted loudly at her.
46. According to Dr Ferrer, which of the following statements is TRUE?
A. We get sick or stay well by ourselves.
B. Only the genes we get from our family have a big effect on our health.
C. Our health has nothing to do with diet, lifestyle and environment.
D. Teenagers who are ignored at home get sick more easily than those who are not.
47. The best title for this passage is ________.
A. Family relations. B. The reasons why we get sick.
C. Happy family makes you healthy. D. A research about teenagers’ health.

If you dream of going someplace warm to escape the cold winter weather, a trip to a recently discovered planet would certainly warm you right up. The planet, named OCLE-TR-56b, has temperatures of more than 3,000 °F. “This is the hottest planet we know about,” says Dr. Dimitar Sasselov, a scientist who led the discovery team. “It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”
The new planet is 30 times farther away than any planet discovered by scientists before. It is in the Milky Way but it is not in our solar system. The new planet moves around a star much like our sun, however. Scientists discovered the planet by using a new planet-searching method, called “transit technique”. They were able to catch sight of the planet when it moved in front of its star, causing the star’s light to dim. Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away. “We believe the door has been opened wide to go and discover planets like Earth,” says Sasselov.
48. We can infer from the passage that____.
A. there is iron on the new planet
B. we could go to the new planet in winter
C. the star could block our view of the new planet
D. scientists are studying the weather on the new planet
49. The “transit technique” can_____.
A. help dim the light of a star                  B. help scientists with a searchlight
C .help discover a bee on a planet              D .help find a planet moving before its star
50. Which is the best title for the passage?
A. New Planet-searching Technique                 B. New Distant Discovery
C. Space Searching                               D. Dream Planet

If you fly non-stop across Canada from Newfoundland in the east to British Columbia in the west, you can arrive before you set out, that is, by the time shown on clocks in British Columbia. Canada is such a big country that people in British Columbia may be having their breakfast while those in Newfoundland are perhaps already beginning their lunch. So the country is divided into five time zones, each an hour behind in time from the west zones to the east. For example, when it is 12 noon Atlantic Time in Newfoundland and the Madritime Provinces, it is 11a.m. Eastern time in most of Quebec and Ontario. Winnipeg, Manitoba, lies in the middle of the Central Time Zone, here it is 10 a.m. In most of the Prairies and the eastern half the mountains it is 9 a.m. Mountain Time while the west coast region has Pacific Time and it is 8 a.m.
45. The underlined word “non-stop” in the first sentence may mean ____.
A. to stop everywhere                            B. no stopping in Canada
C. without stopping before the final stop            D. to stop in Newfoundland
46. Which of the following is not the name of a place in Canada?
A. British Columbia.     B. Newfoundland.    C. Quebec.             D. Atlantic Time.
47. According to the passage, the place named Quebec is to the ___ of the place named Winnipeg.
