题型:单项选择题 A1/A2型题

     Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a

family of seven children, she often felt like she had "seven fathers," because her six brothers, as well as

her father, tried to control her. Feeling shy and unimportant, she retreated(躲避) into books. Despite

her love of reading, she did not do well in elementary school because she was too shy to participate.

     In high school, with the encouragement of one particular teacher, Cisneros improved her grades and

worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for

a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university's Writers' Workshop, however, she felt lonely—a Mexican American from a

poor neighborhood among students from wealthy families. The feeling of being so different helped

Cisneros find her "Creative voice."

     "It was not until this moment when I considered myself truly different that my writing acquired a voice.

I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalance

in my life, but it had everything to do with it! That's when I decided I would write about something my

classmates couldn't write about."

     Cisneros published her first work, The House on Mango Street, when she was twenty-nine. The

book tells about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much

like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been

used in classes from high school through graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a short-story collection.

1. Which of the following is TRUE about Cisneros in her childhood?

D. She did not have any good teachers.

2. The graduate program gave Cisneros a chance to __________.

A. work for a school magazine

B. run away from her family

C. make a lot of friends

D. develop her writing style

3. What do we learn about The House on Mango Street?

A. It is quite popular among high school students.

B. It is the only book ever written by Cisneros.

C. It wasn't a success as it was written in Spanish.

D. It won an award when Cisneros was twenty-nine.
