单选题Not being able to sleep can be dangerous if we ______.A are feeling wellB worry about it too muchC repair our bodies by restingD plan our sleeping lives carefully

If we carry out our plan with（）we will surely achieve our goal sooner or later.

Passage 1Scientistshave found that although we are prone to snap overreactions, if we take amoment and think about how we are likely to react, we can reduce or eveneliminate the negative effects of our quick, hard-wired responses.Snapdecisions can be important defense mechanisms; if we are judging whethersomeone is dangerous, our brains and bodies are hard-wired to react veryquickly, within milliseconds. But we need more time to assess other factors. Toaccurately tell whether someone is sociable, studies show, we need at least aminute, preferably five. It takes a while to judge complex aspects ofpersonality, like neuroticism or open-mindedness.Butsnap decisions in reaction to rapid stimuli aren't exclusive to the interpersonalrealm. Psychologists at the University of Toronto found that viewing a fast-foodlogo for just a few milliseconds primes us to read 20 percent faster, eventhough reading has little to do with eating. We unconsciously associate fastfood with speed and impatience and carry those impulses into whatever elsewe're doing. Subjects exposed to fast-food flashes also tend to think a musicalpiece lasts too long.   Yet we can reverse suchinfluences. If we know we will overreact to consumer products or housingoptions when we see a happy face  (onereason good sales representatives and real estate agents are always smiling),we can take a moment before buying. If we know female job screeners are morelikely to reject attractive female applicants, we can help screeners understandtheir biases-or hire outside screeners. John  Gottman,the marriage expert, explains that we quickly thin slice information reliably only after we ground suchsnap reactions in  thicksliced long-term study. When Dr. Gottman really wants to assess whether a couple will stay together, he invitesthem to his island retreat for a much longer evaluation: two days, not twoseconds. Our ability to mute our hard-wired reactionsby pausing is what differentiates us from animals dogs can think about thefuture only intermittently or for a few minutes. But historically we have spentabout 12 percent of our days contemplating the longer term. Although technologymight change the way we react, it hasn't changed our nature. We still have theimaginative capacity to rise above temptation and reverse the high-speed trend.The time needed in making decisions may_______.

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.

Surveys show that ______ less sleep than we think, ______ too much sleep could even harm our health.
