湖北黄梅一中2014届高三上学期适应性训练（五）英语试题试卷(4)

Two types of chemicals in particular have raised special concern lately. They are called phthalates (邻苯二甲酸盐) 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 (争议). 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 (塑化剂) 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 (渗透) 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.

Brrriiinnng. The alarm clock announces the start of another busy weekday in the morning. You jump out of bed, rush into the shower, into your clothes and out the door with hardly a moment to think. A stressful journey to work gets your blood pressure climbing. Once at the office, you glance through the newspaper with depressing stories or reports of disasters. In that sort of mood, who can get down to work, particularly some creative, original problem-solving work?
The way most of us spend our mornings is exactly opposite to the conditions that promote flexible, open-minded thinking. Imaginative ideas are most likely to come to us when we’re unfocused. If you are one of those energetic morning people, your most inventive time comes in the early evening when you are relaxed. Sleepy people’s lack of focus leads to an increase in creative problem solving. By not giving yourself time to tune into your wandering mind, you’re missing out on the surprising solutions it may offer.
The trip you take to work doesn’t help, either. The stress slows down the speed with which signals travel between neurons (神经细胞), making inspirations less likely to occur. And while we all should read a lot about what’s going on in the world, it would not make you feel good for sure, so put that news website or newspaper aside until after the day’s work is done.
So what would our mornings look like if we wanted to start them with a full capacity for creative problem solving? We’d set the alarm a few minutes early and lie awake in bed, following our thoughts where they lead. We’d stand a little longer under the warm water of the shower, stopping thinking about tasks in favor of a few more minutes of relaxation. We’d take some deep breaths on our way to work, instead of complaining about heavy traffic. And once in the office—after we get a cup of coffee—we’d click on links not to the news of the day but to the funniest videos the web has to offer.
