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.

試題分析：本文講述文章介紹雖然塑料很受歡迎也有很多好處，但是塑料里面的物質(zhì)有可能進入人體照成對身體的傷害，特別是一些嬰兒的塑料制品可能對孩子的健康造成危害。

【1】D分析推理題。根據(jù)第一句：Plastic is everywhere because plastic is an extremely useful material.塑料到處都是因為塑料確實很有用，可知塑料很受歡迎，第二句話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它很便宜，耐用能承重。甚至它能容納任何形式任何形狀的東西，柔軟的有彈性的甚至堅硬的玻璃的都可以，可知講的是塑料的好處，故選D

【2】C細節(jié)理解題。根據(jù)第五段倒數(shù)第二句BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles.可知嬰兒牛奶瓶中有BPA，故選C

【3】A細節(jié)理解題。從倒數(shù)第二段最后一句Even though we can’t see them, we eat them, drink them and breathe them in.可知 Phthalates和BPA是經(jīng)過口鼻進入人體的，故選A

【4】B分析推理題。根據(jù)第二段第一句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, 然而塑料遠不是這么完美。它甚至對我們有壞處。可知這篇文章講的是塑料所產(chǎn)生的問題，故選B
