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?
A.She had seven brothers.
B.She felt herself a nobody.
C.She was too shy to go to school.
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)According to Cisneros,what played the decisive role in her success?
A.Her early years in college.
B.Her training in the Workshop.
C.Her feeling of being different.
D.Her childhood experience.
(4)What do we learn about The House on Mango Street?
A.It is quite popular among students.
B.It is the only book ever written by Cisneros.
C.It wasn't success as it was written in Spanish.
D.It won an award when Cisneros was twenty-nine.

Scientists have always been interested in the high level of organization in ant societies.American researchers have watched ants build life-saving rafts to keep afloat during floods.They also have recorded how ants choose their next queen - the female whose job is to produce eggs.
New technology is helping to improve researchers' understanding of the insects.But there is still a lot to be learned.
Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common.To save themselves,the insects connect their legs together and create floating rafts.Some ant rafts can be up to 20 centimeters wide.
David Hu is an engineer with the Georgia Institute of Technology,also known as Georgia Tech,saying, "If you have 100 ants,which means 600 legs,99 percent of those legs will be connected to a neighbor.So they're very,very good at keeping this network. "
David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering.They froze ant rafts and then looked at them with the help of computed technology,or CT images.The pictureowed that larger ants serve in central positions to which smaller ants hold.The larger ants create pockets of air that keep the insects afloat.
Scientists say small robots or materials that can change shape could be programmed in a similar way,working towards a shared goal.
Researchers at North Carolina State University are also studying ants.They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.
(1)he author takes fire ants as an example to tell us .
A.how ants seek food
B.how ants survive
C.how ants communicate
D.how ants live together
(2)What can we know from what David Hu said in paragraph 4?
A.Ants know the way to join together closely.
B.Ants know the way to keep safe in the river.
C.Ants know the way to look for each other.
D.Ants know the way to build a large raft.
(3)Why did the larger ants serve in central positions in their ant rafts?
A.To stress their importance.
B.To help all the ants float.
C.To fight against the enemies.
D.To defend their top female.
(4)What ideas do the ants give us according to the passage?
A.We can use similar-shaped machines in flooding areas.
B.We can combine small robots or materials into larger ones.
C.Small and shape-changeable things might work just like ants do.
D.Small robots or materials in the shape of ants can be made.

Though its effects are not always visible to the human eye,plastic is choking life on Earth.The process for manufacturing plastic worsens climate change,and the spreading of plastic in the environment has led to heartbreaking sights.
Then there came a daydream:Can we create something that will consume it?
A new study suggests that an enzyme(酶)which targets polyethylene terephthalate(PET) -a widely-used substance found in a majority of consumer packaging products that contains 12 percent of all global waste-could make that scientific dream,which is also necessity,into a reality.
The key ingredient was a natural enzyme known as PETase,according to the paper published in the scientific journal Nature.Using a machine learning model,scientists at the University of Texas figured out what changes would cause the enzyme to be able to quickly break down the targeted types of plastic waste.
"It has been a well-explored problem in many industries," Hal Alper,a professor in Chemical Engineering,said,"Therefore,we feel that this part of the problem is easily achievable in a short period of time.The more challenging aspect will be making enzyme break down on a large scale with mixed plastics waste."
This was not the first effort to solve the plastic pollution problem.In March 2016,Japanese researchers found a bacteria that would "eat" the plastic until it turned into sludge(泥浆).Last year,scientists at the University of Edinburgh announced that E.Coli,a common bacterium,could be used to change PET into a kind of material,which might be able to be safely consumed by humans.
Joanna Sadler,a biotechnology professor at the University of Edinburgh,characterized the new enzyme as the "fastest enzyme reported to date" in terms of the speed of breaking down different plastics. "This makes it a very promising technological development in the field,and demonstrates the better adapted usage of this enzyme,"Sadler said.
(1)What's the function of the first paragraph?
A.To explain a unique phenomenon.
B.To stimulate the readers' curiosity.
C.To analyze the cause of the situation.
D.To provide some background information.
(2)What is the challenging problem scientists are facing?
A.Turning the scientific dream into a reality.
B.Causing the enzyme to work more effectively.
C.Putting a machine learning model into practice.
D.Making the enzyme dissolve plastics massively.
(3)Why are the examples mentioned in Paragraph 6?
A.To evaluate the scientists' previous efforts.
B.To introduce some similar biological means.
C.To prove the possibility of recycling plastics.
D.To stress the importance of plastic-eating bacteria.
(4)Which word best describes Sadler's attitude to the enzyme?
A.Skeptical.
B.Objective.
C.Optimistic.
D.Critical.
