　　TWO teams of astronomers using the Hubble Space Telescope and other instruments have found evidence(证据)of a type of black hole that has never been seen before.

　　Roeland Van Der Marel of the Space Telescope Science Institute in Baltimore said last week his group has confirmed(证实) the existence of a midsized black hole in a cluster (group) of stars called M15, about 32,000 light years away.

　　Yan Der Marel said the black hole has about 4,000 times the mass of the sun, which makes it the smallest galactic(银河的)black hole ever found.

　　Another group, led by Michael Rich of the University of California, Los Angeles, looked into a cluster of stars called GI and found a black hole that has about. 20,000 times the mass of the sun. It is some 2.2 million light years away.

　　Using the motion of stars within the clusters, the astronomers could determine the mass of the star groups and of the black holes. They found that the ratio(rate) of the mass of black holes to the mass of globular (球状的) clusters (smaller than a galaxy ) was precisely (精确地) the same as the ratio between supermassive (超质地的) black holes and galaxies. This suggests a neat, uniform(一致的) universal truth that applies the same mass ratio to black holes of all sizes everywhere, explains Karl Gebhardt of the University of Texas, a member of the G1 team.

　　The new discovery may help astronomers answer a basic question: Which came first. galaxies or black holes? Both theories have been proposed and finding intermediatesized(中等规模的) black holes may help answer that question.

1．The astronomers from ________ American institutes and universities discovered the black holes.

[　　]

2．Where do the black holes exist?

[　　]

A．In a cluster of stars called M15.

B．In a clusters of stars called G1

C．In clusters of stars of the galaxy.

D．Between the sun and the earth.

3．Which of the following is NOT true?

[　　]

A．The scientists determined the mass of the black holes using the motion of stars within the clusters.

B．Midsized black holes can give evidence for the answer to“Which came first, galaxies or black holes”.

C．The ratio of the mass of black holes of all sizes is the same.

D．The ratio of the mass between supermassive black holes and galaxies is larger than that between black holes to the mass of globular clusters.

4．Which is the most proper title of the article?

[　　]

A．Search for the origin of black holes

B．More black holes are discovered

C．Which came first, galaxies or black holes?

D．Search for more black holes

The Girl Who Fell From the Sky
From its opening lines – “ ‘You my lucky piece,’ Grandma says.... Her hand is wrapped around mine” – Heidi W. Durrow pulls us into her first novel, a moving story encircling us as firmly as that protective grandmotherly grip.
When we meet Rachel Morse, the daughter of an African-American GI and a Danish woman, she is just moving into the Portland, Oregon., home of her strong-minded paternal grandmother and her warm, classy Aunt Loretta. We soon learn that Rachel has survived a fall from a nine-story apartment building in which her mother, brother, and baby sister all died. Three months earlier, Rachel’s mother had left her alcoholic husband in Germany, following her “orange-haired” lover to Chicago. But Nella hadn’t been prepared for boyfriend’s drinking and racism, or for the looks and questions she gets as the mother of three brown children.
Rachel’s “new-girl feeling” in her grandmother’s home goes beyond her recent tragedy. Having grown up with a Scandinavian mother in the more colorblind society of an overseas Army base, this is her first time in a mostly black community. Her light-brown skin, “fuzzy” hair, and blue eyes raise questions about her racial identity that are entirely new and puzzling to her.
Starting sixth grade in her new school, Rachel notes, “There are fifteen black people in the class and seven white people. And there’s me. There’s another girl who sits in the back. Her name is Carmen LaGuardia, and she has hair like mine, my same color skin, and she counts as black. I don’t understand how, but she seems to know.” Several years later, in high school, her status remains uncertain. “They call me an Oreo. I don’t want to be white. Sometimes I want to go back to being what I was. I want to be nothing.”
Winner of the Bellwether Prize, created by Barbara Kingsolver to celebrate fiction that addresses issues of social injustice, “The Girl Who Fell From the Sky” comes at a time when bi-racial and multicultural identity – so markedly represented by President Obama – is especially topical.
But set in the 1980s and focusing on one unusually sympathetic girl overcoming family tragedy and feeling her way through racial tensions, Durrow’s novel surpasses topicality.
Like Rachel, Durrow is the light-brown-skinned, blue-eyed daughter of a Danish mother and an African-American father enlisted in the Air Force. With degrees from Stanford, Columbia Journalism School, and Yale Law School, it’s no wonder she gives her heroine discipline and brains.
Rachel’s life, however, is clearly not Durrow’s. No, there’s alcohol and drug addiction; deaths by fire, trauma, and infection. There are mothers who lose their children, and a saintly drug counselor who loses his beloved girl-friend. Through it all, what makes Durrow’s novel soar is her masterful sense of voice, her assured, delicate handling of complex racial issues – and her heart.
After hearing the blues music for the first time, Rachel feels what her mother called hyggeligt – “something like comfort and home and love all rolled into one.” She wonders what might have happened if her mother had known about such soulful music, “that sometimes there’s a way to take the sadness and turn it into a beautiful song.”
This, of course, is precisely what Durrow has done in this powerful book: taken sadness and turned it into a beautiful song.
60. What should be the direct cause of Rachel coming to Portland, Oregon?
A. Her mother left her alcoholic father.
B. A deadly tragedy happened to her family.
C. Her grandmother wants her to come and stay with her.
D. There was too much racism where she used to live with her mother.
61. Durrow’s life is different from Rachel’s in that _____________.
A. Durrow has to struggle through her life, depending on herself.
B. Durrow is troubled in her life by racism, living in a poor neighborhood.
C. Durrow has come through life much easier, with a better family background.
D. There’s alcohol and drug addiction in Durrow’s suffering-laden neighborhood.
62. Why does the writer of the book review mention President Obama in this writing?
A. To show the progress in America’s black community.
B. To highlight the racial harmony in the United States.
C. To indicate Obama’s influence in helping Durrow win the Bellwether Prize.
D. To remind readers of the background when the novel was written and won the Bellwether Prize.
63. The blues music Rachel hears is, deep at the bottom of her heart, most suggestive of ______.
A. bravery B. hope C. sadness D. beauty
