Text 3 Scientists have found that although we are prone to snap overreactions,if we take a moment and think about how we are likely to react,we can reduce or even eliminate the negative effects of our quick,hardwired responses.Snap decisions can be important defense mechanisms;if we are judging whether someone is dangerous,our brains and bodies are hardwired to react very quickly,within milliseconds.But we need more time to assess other factors.To accurately tell whether someone is sociable,studies show,we need at least a minute,preferably five.It takes a while to judge complex aspects of personality,like neuroticism or openmindedness.But snap decisions in reaction to rapid stimuli aren't exclusive to the interpersonal realm.Psychologists at the University of Toronto found that viewing a fastfood logo for just a few milliseconds primes us to read 20 percent faster,even though reading has little to do with eating.We unconsciously associate fast food with speed and impatience and carry those impulses into whatever else we're doing.Subjects exposed to fastfood flashes also tend to think a musical piece lasts too long.Yet we can reverse such influences.If we know we will overreact to consumer products or housing options when we see a happy face（one reason good sales representatives and real estate agents are always smiling）,we can take a moment before buying.If we know female job screeners are more likely to reject attractive female applicants,we can help screeners understand their biases—or hire outside screeners.John Gottman,the marriage expert,explains that we quickly“thin slice”information reliably only after we ground such snap reactions in“thick sliced”longterm study.When Dr.Gottman really wants to assess whether a couple will stay together,he invites them to his island retreat for a much longer evaluation;two days,not two seconds.Our ability to mute our hardwired reactions by pausing is what differentiates us from animals:doges can think about the future only intermittently or for a few minutes.But historically we have spent about 12 percent of our days contemplating the longer term.Although technology might change the way we react,it hasn't changed our nature.We still have the imaginative capacity to rise above temptation and reverse the highspeed trend.To reverse the negative influences of snap decisions,we should_____A.trust our first impressionB.do as people usually doC.think before we actD.ask for expert advice

问答题Practice 4 Directions: Read the text below. Write an essay in about 120 words, in which you should summarize the key points of the text and make comments on them. Try to use your own words. In our modern world, when something wears out, we throw it away and buy a new one. The problem is that countries around the world have growing mountains of rubbish because people are throwing out more rubbish than ever before. How did we become a throwaway society? First of all, it is now easier to replace an object than to spend time and money to repair it. Thanks to modern manufacturing (制造业) and technology, companies are able to produce products quickly and inexpensively. Products are plentiful and cheap. Another cause is our love of disposable (一次性的) products. As busy people, we are always looking for ways to save time and make our lives easier. Companies produce thousands of different kinds of disposable products: paper plates, plastic cups, and cameras, to name a few. Our appetite for new products also returns to the problem. We are addicted to buying new things. Advertisements persuade us that newer is better and that we will be happier with the latest products. The result is that we throw away useful possessions to make room for new ones. All around the world, we can see the consequences of this throwaway lifestyle. Mountains of rubbish just keep getting bigger. To decrease the amount of rubbish and to protect the environment, more governments are requiring people to recycle materials. However, this is not enough to solve (解决) our problem.

问答题In this section, there is one passage followed by a summary. Read the passage carefully, and then complete the summary below by choosing a maximum of three words from the passage to fill in each of the blanks. Remember to write the answers on the answer sheet. Questions 1 to 5 are based on the following passage. Everyone knows about pollution in the environment. Water, air, and land are all polluted. This means that pollution is everywhere. Now, scientists are looking inside our bodies to find out about internal pollution. In 2003, the Environmental Working Group studied nine people to measure the chemicals in their bodies. These nine people had an average of 53 cancer-causing chemicals in their bodies. They also had an average of 62 chemicals that can damage the brain, and 55 that can harm babies in pregnant women. Even though a lot of chemicals were found in human bodies, the chemicals were found in small amounts. The amounts were small enough that they were probably not hurting the people. However, scientists are worried because most of these chemicals were created by humans. Most of these chemicals did not exist 75 years ago. This proves that we have not only polluted the world—we have polluted our own bodies! How does this pollution get into our bodies? We come into contact with many chemicals every day. For example, everyone uses soap, skin lotion, and shampoo. However, few people know that these products contain harmful chemicals, some of which may cause memory loss. Chemicals known as DEA (diethanolamine) and TEA (triethanolamine) may seep into the skin and stop us from absorbing a helpful nutrient called “choline”. Choline is a nutrient that plays a crucial role in the memory cell making process in the developing brain. Some people worry that every time we wash our hair, we are decreasing our memories. Everyone knows they should brush their teeth regularly, but recent research has shown that some toothpastes can cause cancer. Fluoride is a key ingredient in many toothpastes. However, studies show that fluoride does not really protect our teeth. In fact, fluoride has been connected with bone cancer and other diseases. While we are trying to save our smiles, we could be damaging our health. Women are probably exposed to more chemicals than men because they use more beauty products. Recently, harmful chemicals have been found in nail polish, hair spray, deodorant, and perfume. The chemicals are called “phthalates”. Studies on animals have shown that phthalates can damage the liver, the kidneys, and the lungs. Cosmetic companies say the amounts of phthalates in their products are safe, but consumer protection groups disagree. They say some women use so many products that the levels are actually high. So, the more women try to look beautiful, the more they could be harming their health. In a futuristic story by Ray Bradbury, a man found a pristine stream on a new planet. When he drank from the stream, he died! Why? His body was so polluted that pure water was a poison to him! Perhaps that is only science fiction, but it reminds us to take care of our bodies. We must find ways to reduce the pollution we absorb. Summary: Like our polluted environment, our bodies are no longer pollution-free. Scientists now know that there is pollution in our bodies. On 1 , we have 53 cancer-causing chemicals in our bodies. Even fluoride 2 with bone cancer and other diseases. Some common cosmetics contain small amounts of chemicals, which seep into our 3 when we use these products. They prevent us from absorbing the 4 our bodies need. So, it is 5 that we find ways to reduce the amount of chemicals in our bodies. We should remind our friends and families to take care of their bodies.
