第三部分:閱讀理解(共20小題,共40分)
第一節(jié)(共15題, 每小題2分,滿分30分)
閱讀下列短文,從每題所給的四個選項(A,B,C和D)中,選出最佳選項。                              
A
What secret force drives us into the arms of one person, while pushing us away from another who might appear equally desirable to any fair observer? Of the many factors influencing our idea of the perfect mate, one of the most telling is our “l(fā)ovemap” ---- a group of messages formed in our brains that describes our likes and dislikes.It shows our preferences in hair and eye color, in voice, smell, body build.It also records the kind of personality that attracts us, whether it’s the warm and friendly type or the strong silent type.In short, we fall for and go after those people who most clearly fit our lovemap.And this lovemap is determined in childhood.By age eight, the pattern for our ideal mate has already begun to float around in our brains.
The mother has special influence on her sons: she not only gives them clues to what they will find attractive in a mate, but also influences how they feel about women in general.So if she is warm and nice, her sons are going to think that’s the way women are.They will likely grow up warm and responsive lovers and also be helpful around the house.
Just as mothers influence their son’s general feelings toward women, fathers influence their daughter’s general feelings about men.If a father lavishes praise on his daughter and shows that she is a worthwhile person, she’ll feel very good about herself in relation to men.But if the father is cold, critical or absent, the daughter will tend to feel she’s not very lovable or attractive.
While the mother determines in large part what qualities attract us in a mate, it’s the father ----- the first male in our lives ----- who influences how we relate to the opposite sex.Fathers have a great effect on their children’s personalities and chances or marriage happiness.
56.What is the proper title for this passage?
A.Why we love who we love           B.What is a lovemap
C.Different influence from parents        D.Ideal mate in the mind
57.A perfect mate is a person who ____.
A.is fair to everyone               B.is the most desirable
C.fits one’s lovemap               D.is perfect in everything
58.If the husband hardly does any housework, ____.
A.his mother must be warm             B.his father must be critical
C.his mother must be cold               D.his wife can’t be attractive
59.The passage leads to a belief that ____.
A.parents’ personalities decides the children’s lovemap
B.mothers have no influence on daughters’ marriage life
C.fathers care more about children’s marriage happiness
D.mothers influence children’s choices of perfect mates
