Passage Four

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 otherPVC 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.

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.

49.What material are the shower curtains sold at IKEA made from?

D.PVC and EVA.

50.What's the biggest problem with hemp and cotton shower curtains?

A.They are see-through.

B.They are too expensive.

C.They may cause mildew.

D.They emit harmful materials.

51.Is it easy for consumers to tell that a shower curtain is made from PVC?

A.Yes,that information is always on the shower curtain label.

B.Not always,because shower curtains don't have to be labeled.

C.Yes,but only if they're made by IKEA after 2008.

D.No,because they only contain low doses of PVC.

第四篇

【答案】

48.D49.A50.C51.B

【解析】

48.这篇文章是关于浴室的浴帘含有聚氯乙烯的问题。第一段指出，健康环境及正义中心发布了一个研究报告，证实含有聚氯乙烯的浴帘可放射大量的有害物质。选项D是正确的。

49.第三段。11年前宜家就开始逐步淘汰含有聚氯乙烯的浴帘，而改用乙烯醋酸共聚物。选项A是正确的。

50.最后一段，最后一句。用棉或麻做的浴帘的最大问题是会发霉。选项C是正确的。

51.最后一段，第一句。并没有要求厂家一定要在浴帘上贴标签，但有些厂家的确在包装上打上含有聚氯乙烯的标签。所以消费者不会很清楚他所买的浴帘是否含有聚氯乙烯。选项B

是正确的。

【原文大意】

作为抵制聚氯乙烯的持续战役的一部分，弗吉尼亚州的环境保护组织号召厂家和零售商逐步淘汰含有聚氯乙烯的浴帘。健康环境及正义中心发布了一个小型的研究结果，证明含有聚氯乙烯的浴帘会在人们使用的卫生间里放射大量的潜在有害物质。环境保护部的研究员们在先前所做的研究中也发现了塑料的浴帘会向空气中释放有毒的混合物。

但就对健康的影响到底有多严重，科学家们仍有分歧，尤其是在小剂量的情况下。不过，健康环境及正义中心力劝消费者不要使用聚氯乙烯的浴帘，以及其他许多含有该物质的产品。

担心自己浴帘的人还有其他的选择。宜家在11年前就在逐步淘汰含有聚氯乙烯的浴帘，转而使用乙烯醋酸共聚物。宜家说到2008年的春天，88%的浴帘将不含聚氯乙烯。

没有要求厂家一定要在浴帘上标明是否含有聚氯乙烯，但有些厂家在包装上将聚氯乙烯列入表内。众多的网上零售商出售的主要是麻或棉布制作的浴帘，而不含聚氯乙烯。然而，麻和棉布制作的浴帘很容易发霉。
