Even with little exposure to cultural standards of beauty, “infants treat attractive faces as  distinctive regardless of the sex, age a nd race of the stimulus(刺激物) faces,”  write psychologist Judith H.Langlois and her colleagues in the January DEVELOPMENTAL PSYCHOLOGY.

In their experiment, 5 healthy 6-month-old infants from middle-class families viewed slides showing eight pairs of white male faces and eight pairs of white female faces. Each pair, displayed for 10 seconds, consisted of one attractive and one unattractive face, as previously judged by a group of male and female college students. An experimenter viewed the young participants on a video monitor and recorded the direction and duration of each infant’s gaze.

The 35 boys and 25 girls looked longer at both male and female faces judged as attractive, the researchers found.

Their second study of 6-month-old involved 15 boys and 25 girls, mostly white, who saw eight pairs of slides showing an attractive and an unattractive black female, as previously judged by both white and black college students.  Again, the babies looked much longer at attractive faces.  

Finally, 19 boys and 20 girls, all 6 months old and almost all of them white, viewed eight pairs of slides showing the faces of 3-month-old boys and girls previously rated as attractive or unattractive by college students. Attractive baby faces drew signficantly longer looks, the psychologists report.

Further studies must explore whether infants take attractive faces as “best examples” of a face, the investigators claim Langlois and a coworker recently reported that attractive faces may possess features that approximate the mathematical average of all faces in particular population.

1.What was found in the first study?

A.Male infants looked longer only at female ones.

B.Females looked more attractive than males.

C.Sixty 6?month?old babies looked longer at the attractive faces, male or female.

D.White female faces drew more attention  than those of black ones.

2.In the last paragraph, the writer implies that .      

A.Langlois and her partners will stop their experiments they accomplished a lot

B.Langlois and her partners will focus on the other fields of infants

C.Langlois and her partners have achieved success in studying the infants’ mind

D.Langlois and her partners have found a more interesting field

3.What can be inferred from the passage?

A.All babies, white or black, tend to share with the college students the preference for attractive faces.

B.White babies prefer white faces to black ones.       

C.Babies tend to get interested in the attractive faces of the opposite sex.

D.Beauty has something to do with a person’s age, race and sex

4.The title that best expresses the main idea is .     

A.Psychology of Infants   B.Beauty in Variety   C.Beauty and Race   D.Beauty in Infants

Homework is an important part of education. However, what is it about homework? What makes it important?
First, homework helps students learn. Homework produces higher learning ability by asking the student to read the same text many times.
Most of the time, homework will ask students to read other books. So children have to read and understand it by themselves. Sometimes, parents must help children with this type of learning. Children hope to use what they have read to solve questions and problems in the homework.
Good use of homework makes children know that learning can happen with or without the teacher.
As homework is finished, students learn to work out their own problems. Most students need a little help now and then, but doing homework is a way that children can learn to take care of themselves. If the student can do his or her own work, it is likely the ability he gets will be good for their future life.
Most homework gives room for additional(額外的) learning. Short answers, long answers and papers provide a way for students to learn things that interest them. Science can give the student a chance to go deeper into a field and have a better understanding. These things are almost impossible within the classroom education. If the project is done by a group, the students will also learn cooperation(合作).
Good study skills students get from homework and test preparation can be used easily in most work places.
