Question

【題目】Plastic is everywhere because plastic is an extremely useful material．It is cheap, strong and lightweight．What’s more, it can take on nearly any form or shape, from soft and stretchy （有彈性的） to hard and glasslike.

Plastic, however, is far from perfect．It may even be bad for us．Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder （注意缺陷障礙）.

Two types of chemicals in particular have raised special concern lately．They are called phthalates （鄰苯二甲酸鹽） and Bisphenol-A （二酚基丙烷）, BPA for short． Not all plastic products contain them．But the ones that do are surrounded by controversy （爭議）．That’s because experts disagree on how dangerous these chemicals are.

Plastic is a single word, but plastic isn’t just one thing．What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture．Plasticizers （塑化劑） are added to plastic during the manufacturing process.

Phthalates and BPA are two types of plasticizers that work in different ways．Phthalates add softness to things like shampoo bottles, raincoats and rubber．They are also used in perfumes and makeup．BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles．BPA also appears in food and soda cans, DVDs and other unexpected places.

How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep （滲透） out of the plastic．Even though we can’t see them, we eat them, drink them and breathe them in.

Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic．Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three．California and Washington have done the same．And a number of other states are considering similar rules．As for BPA, Canada became the first country to ban the chemical from baby bottles．A dozen states are considering it.

【解析】

試題分析:本文是一篇科技文，講述的是有些塑料中的化學成分對人體健康有害。例如，最近引起了人們的廣泛關注的塑料中對人體有害的兩類化學成分：鄰苯二甲酸鹽和二酚基丙烷。有些嬰兒的奶瓶中包含二酚基丙烷，對嬰兒健康造成巨大影響。許多國家采取了一些措施，例如，未滿三歲的兒童禁止使用含有二酚基丙烷的奶瓶。

【1】D推理判斷題。根據(jù)第一段Plastic is everywhere because plastic is an extremely useful material．It is cheap, strong and lightweight．What’s more, it can take on nearly any form or shape, from soft and stretchy to hard and glasslike.可以判斷塑料是十分有用的材料。它的優(yōu)點是便宜，堅韌，輕便。故選D。

【2】C細節(jié)理解題。根據(jù)第五段 BPA, on the other hand, gives a hard, clear, almost glasslike feel to

products such as infant bottles.可知嬰兒牛奶瓶中包含BPA，故選C。

【3】A細節(jié)理解題。由第六段 Even though we can’t see them, we eat them, drink them and breathe

them in. 可知塑料可以通過我們的嘴巴、鼻子進入人體內(nèi)，故選A。

【4】B主旨大意題。根據(jù)第二段Plastic, however, is far from perfect. It may even be bad for us. 可以判斷塑料并不完美，它也有缺點，因塑料的使用引發(fā)了許多問題，故選B。
