As part of an ongoing campaign against polyvinyl chloride (聚氯乙烯 ), a Virginia-based
environmental advocacy group today called on manufacturers and retailers to phase out its use in shower curtains． The Center for Health, Environment and Justice (CHEJ) , released the results of a small study indicating that PVC ( 聚氯乙烯)-containing shower curtains are capable of emitting scores of potentially harmful materials, into people's bathrooms． A previous study, conducted by Environmental Protection Agency researchers, also found that plastic shower curtains can emit toxic compounds into the air．
There's still debate among scientists about just how serious the health effects are especially at low doses． However, CHEJ urges consumers to avoid using PVC shower curtains, as well as many other PVC products．
For people who are concerned about their shower curtains, there are alternatives． IKEA phased out PVC shower curtains 11 years ago, switching to ethylene vinyl acetate (乙烯醋酸共聚物)． The company has said that 88 percent of its shower curtains would be PVC free by spring of 2008．
Manufacturers are not required to label shower curtains, but some do list" PVC" or" vinyl" on the packaging． Numerous online retailers, sell shower curtains--primarily cotton or hemp--that are free of PVC． However, mildew(发霉) can be a problem with cotton and hemp products．

What did the study released by the Center for Health, Environment and Justice show?
A．That PVC stands for polyvinyl chloride．
B．Manufacturers are not required to label shower curtains．
C．That most shower curtains sold at IKEA are made from PVC．
D．That PVC shower curtains may release potentially harmful materials．

39、

C．Yes, but only if they're made by IKEA after 2008．
D．No, because they only contain low doses of PVC．

Love is a wondrous state, deep, tender, and rewarding．Because of its intimate and personal　nature, it is regarded by some as an improper topic for experimental research．But, whatever our personal feelings may be, our assigned mission as psychologists is to analyze all facets (方面) of human and animal behavior into their component variables．So far as love or affection is concerned, psychologists have failed in this mission．The little we know about love does not transcend simple observation, and the little we write about it has been written better by poets and novelists．But of greater concern is the fact that psychologists tend to give progressively less attention to a motive which pervades our entire lives．Psychologists, at least psychologists who write textbooks, not only show no interest in the origin and development of love or affection, but they seem to be unaware of its very existence．The apparent repression of love by modern psychologists stands in sharp contrast with the attitude taken by many famous and normal people．The word "love" has the highest reference frequency of any word cited in Bartlett's Book of Familiar Quotations．It would appear that this emotion has long had a vast interest and fascination for human beings, regardless of the attitude taken by　psychologists ; but the quotations cited, even by famous and normal people, have a mundane redundancy．These authors and authorities have stolen love from the child and infant and made it the exclusive property of the adolescent and adult．

According to the passage,________
A．poets and other authors have deemed romantic love the only type of love
B．only adults and adolescents are capable of feeling true love
C．modern psychologists realize the importance of studying love
D．love belongs solely in poetry books

A．Social science should not deal with human emotions．

42、 The best statement of the main idea for the passage is ________

B．love is a wondrous state, deep, tender and rewarding
C．psychologists write terrible textbooks because they ignore love
D．psychologist must study all aspects of human behavior, including love

A．objective
B．ironic
C．condescending
D．fond

How many things can you see in the night sky? A lot! On a clear night you might see the Moon,some planets, and thousands of sparkling stars．You can see even more with a telescope．But scientists believe there are some things in the sky that we will never see．We won't see them with the biggest telescope in the world, on the clearest night of the year．That's because they're invisible．They're the mysterious dead stars called black holes．As a star's gases burn, they give off light and heat．But when the gas runs out, the star stopsburning and begins to die．As the star cools, the outer layers of the star pull in toward the center．The star squashes(挤压 )into a smaller and smaller ball．If the star was very small, the star ends up as a cold, dark ball called a black dwarf．If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe．Imagine if the Earth were crushed until it was the size of a tiny marble．That's how tightly thisdead star, a black hole, is packed．What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump--the force called gravity．A black hole is so tightly packed that its gravity sucks in everything--even light．The light from a black hole can never come back to your eyes．That's why you see nothing but blackness．So remember: Scattered in the silent darkness are black holes--the great mystery of space．

According to the article, what causes a star to die?
A．As its gases run out, it cools down．
B．It collides with other stars．
C．It can only live for about a million years．
D．As it gets hotter and hotter, it explodes．


45、 Which word has the same meaning with the word "mysterious"?
A．ordinary
B．bright
