She was also worried about the damage all the plastic【C3】______was doing to the environment. So she【C4】______on her bike and rode to the nearest grocery store to see what she could find that didn't【C5】______plastic. "I went in and【C6】______bought anything," Haegele says. She did【C7】______some canned food and a box of milk—【C8】______discover later that both containers were【C9】______with plastic materials. "Plastic," she says, "just seemed like it was in everything." She's right. Back in the 1960s, plastic was well【C10】______its way to becoming a staple of American life. The U.S. produced 28 million tons of plastic waste in 2005—27 million tons of which【C11】______in waste dump. Our food and water come【C12】______in plastic. It's used in our phones and our computers, the cars we drive and the planes we ride in. But the【C13】______adaptable substance has its dark side. Environmentalists feel worried about the petroleum needed to make it. Parents worry about the possibility of【C14】______chemicals making their way from【C15】______plastic into children's bloodstreams. Which means Haegele isn't the only person trying to cut plastic out of her life—she isn't【C16】______the only one blogging about this kind of【C17】______. But those who've tried know it's【C18】______from easy to go plastic-free. "These things seem to be so common【C19】______it is practically impossible to avoid coming into【C20】______with them," says Frederick vom Saal, a biologist at the University of Missouri.
单选题
【C1】
【正确答案】
A
【答案解析】解析：上下文语义题。文章第一句说Jeanne Haegele想知道哪里可以找到无塑洗发水，而空格后一句又讲到她担忧(was concerned about)塑料里的化学物质会对身体怎样。可见，找无塑洗发水是因为她不想用塑料产品，A项resolved“下决心”可用于“______to do sth．”结构，表示“下定决心做某事”，体现不用塑料产品的决心，符合句意。
单选题
【C2】
【正确答案】
B
【答案解析】解析：语义逻辑题。空格处应填入宾语从句的引导词，该从句的主干为the chemicals might be doing to her body，动词do缺少宾语成分，能在宾语从句中充当宾语成分，且作为might be doing所作用的对象的，只能用疑问代词what，选B项。

【C3】
【正确答案】
D
【答案解析】解析：上下文语义题。这里承接上一句讲述了Jeanne Haegele的另一种担忧(was also worried about)，空格前提到the damage“破坏”，其对象是the environment“环境”，空格处填入的名词被plastic所修饰。文章开篇就提到Haegele要找无塑洗发水，可见她不想用含有塑料的产品。根据这一语境，可推出她担忧的应是塑料产物对环境造成损害，rubbish“垃圾”符合句意。
【答案解析】解析：上下文语义题。上文说到去商店买东西，空格后的宾语又为食物canned food and a box of milk。破折号后面的discover later that both containers were…“后来发现这两种容器……”表明只有买了这些东西，才会有所发现，故选D项purchase“购买”，表示“她的确买了一些罐装食品和一盒牛奶”。
【答案解析】解析：上下文语义题。此处空格填入修饰词说明是什么样的chemicals“化学物质”。前面提到塑料有黑暗的一面(has its dark side)，由此可见，父母担心的应是塑料所具有的有害成分，故修饰chemicals的形容词应具有消极含义，toxic“有毒的”为最佳答案，与chemicals连用表示“有毒的化学物质”。
【答案解析】解析：上下文语义题兼考查固定搭配。上一句讲到Haegele并不是唯一试图把塑料从生活中清除出去的人，根据空格后的easy to go plastic-free“容易做到无塑化”，结合转折词But，可推断此处是讲实现无塑化不容易。空格处填入的词跟from连用需能表示否定含义，“far from+形容词”表示“远非……”，选C项。
