专题六阅读填空第二十四讲信息的表述(1)(10 min.)When I opened my e­mail the other day, a pretty woman named Rachel appeared on my computer screen. She greeted me by name and started talking with great enthusiasm. Every now and then she stopped to smile at me or blow a kiss. She was reading to me an e­mail from my brother, and a lot of it was about his getting the phone company to give him a high­speed Internet connection. It was pretty cool. Rachel was there thanks to a new technology called Facemail. Facemail lets you send e­mail that can read mails to the receiver by an attractive male or female form or by a clown. The software, which is free, can be downloaded at Facemail . Facemail faces are lifelike, and they copy emotions based on the ones that you put in your text. For example, type in X, and Rachel blows a kiss.Life FX, the company that develops the Facemail, is sure there are broad business uses. The reason e­business is not popular, the company says, is that buying over the Internet lacks the human touch. But what if you went to the Nike website and Michael Jordan greeted you by name, waited on you and personally closed the sale? Besides, the company is talking with Whirlpool company about the technology in a computer screen on a fridge. Then if Mom can't be at home when the kids get back from school, she can leave a note with voice and image telling them what there is to eat.Facemail could get hot fast. Personally, I am a fan. But Facemail should be used with words in an e­mail and add angry emotions wh en you've got junk mails.Title: A New Technology on 1. __________Ⅰ.

Many now believe that colors can not only cause emotional reactions, but can also correct mood. Colors behave in three basic ways: active, passive and neutral (中和的).Active colors are warm colors, including yellow, orange and red. These colors bring confidence. Warm colors can also bring cheerful attitudes. Yellows and golden colors work well in offices, kitchens and study areas. Reds heat up a room. Passive colors or cool colors make people calm, quiet and satisfied. Bedrooms, private areas and bathrooms are great places for blues and greens. Beige, gray and white are thought of as neutral colors. They help to put the focus on other colors or serve to tone down (使柔和) colors that might otherwise be overpowering on their own.You can easily change the look or feel of a room by making good use of different colors. Mixing and matching colors is an excellent way to balance color and emotion, and provide a welcoming feel for guests.To create a feeling of warmth and comfort in a room, use bright, warm colors like yellow, orange and red. These colors are good choices for rooms that appear cool due to limited sunlight. Yellow adds cheerfulness to dull rooms. You can add yellows to rooms which are not closely relatedto happy thoughts, such as kitchens and laundry room. In rooms where there's plenty of sunshine, cool colors can provide a calming environment. Sage greens and sky blues are perfect for bedrooms, playrooms and activity areas. Neutral colors, such as pale gray, white and beige, send a peaceful message to your brain. It's not a coincidence that most doctor's offices, coffee shops and mental health centers are decorated in neutrals.To make your wall color choices better, pick out furniture that will provide a visual contrast. Cool colors make a room seem larger than it is and warm colors make rooms feel smaller.Title: The Connection between 1. ____________(3)(12 min.)(湖南省岳阳市一中2012届高三模拟)It's easy to see how the sawfish(锯鳐)got its name. These frightful creatures can grow to be more than 6 meters long. Their bodies are flat and winged, like underwater airplanes. And their noses are shaped like chainsaws.Sawfish are food hunters of the sea. When a sawfish is hungry, it waves its sharp­toothed snout (口鼻部) through a group of fish. Then, it lifts its nose and uses its mouth to draw the injured victims.Hardy (适应力强的) population of sawfish thrived in warm waters along coastlines around the world for thousands of years. Over the past 200 years, however, human actions have severely endangered sawfish. Threats include fishing nets that trap the huge animals, often by mistake.Some people collect sawfish's snouts as prizes: One snout recently sold for nearly $1,600 online. In some Asian cultures, the toothy snouts are used in ceremonies to drive evil and disease away. And sawfish are also delicious. A growing demand in Asia for the fish's fins for a pricey (高价的)soup has contributed to the fish's loves. Compared with other fish, sawfish give birth late in life and at slow rates, which makes it hard for them to recover from overfishing.New efforts now aim to restore sawfish population. Beginning next month, an international agreement will provide protection for all seven of the world's sawfish species. Scientists are hoping that it's not too late to save the sawfish.Until 1998, “this fish had never been formally studied in the United States, 〞 says Tonya Wiley of the Mote Marine Laboratory in Sarasota, FL. “We d idn't know such basic things as where they live, what habitat they use, how often they breed, how many young they have — even what age sawfish are when they begin breeding.〞Through historical studies and field research, scientists have become aware of how much the fish's numbers have decreased. Today, there may be 90 percent fewer sawfish than there used to be. Wiley estimates that only 3, 000 to 6, 000 sawfish remain in US waters.Title: Sawfish(4)(10 min.)(2011届娄底市第五次月考英语试卷)A migraine headache (偏头疼) can cause disabling pain. People may not feel back to normal for hours or even for days.Migraine headaches are most common among young adults and middle­aged people. In the United States, about eighteen percent of women and six percent of men report having migraines.People who suffer from migraines can find that different “triggers〞 in different people may get a headache started. Stress can act as a trigger.Many migraine sufferers say hot weather and low barometric pressure(低气压)can act as triggers, but researchers say they did not have much scientific evidence of that — until now.In a new study, a team examined the medical records of seven thousand hospital patients. The patients had visited the emergency room at Beth Israel Deaconess Medical Center in Boston, Massachusetts, because of a headache. More than two thousand of them had been found to have a migraine.The team then compared those records to weather conditions in the twenty­four hours before the hospital visits. For every increase of five degrees Celsius in air temperature, the patients had a seven and one­half percent higher risk of migraine. Decreases in barometric pressure two to three days before the visit also appeared to cause headaches.A separate study has found that age, gender and where a person has extra body fat may affect the risk of migraine. It found that overweight people between the ages of twenty and fifty­five may have a higher risk. On average, those who were larger around the middle were more likely to have migraines than those of the same age with smaller waistlines(腰围).Experts suggest that losing weight in the stomach area may help younger people who experience migraines, especially women. Doing exercises regularly is also helpful to reducing migraineheadaches.Title: 1. __________答案第二十四讲信息的表述(1)本文为说明文。

今年安徽高考题的书面表达也和前三年一样 是半开放类的。一方面考生发挥的余地较大;同 时考生在写作中也容易离题。考生首先要表明 自己是选择文科还是理科,然后再重点阐述自己 的理由,使人信服。
从高考英语书面表达的发展趋势看,2013 年 的高考在体裁上应该保持相对稳定,话题仍然会 与学习、生活、社会活动以及熟悉的社会热点 紧密联系,开放类作文所占的比例会更大。

Johnston and his team found that 14 weeks later, the gum chewers had a 3 percent increase in their math scores on the Texas Assessment of Knowledge and Skills achievement test, a small but statistically significant change, according to experts. There was no difference found in math scores between the participants in the two groups in another test called the Woodcock Johnston Ⅲ Tests of Achievement. However, the experiment revealed(展现) that gumchewers had better final grades in the class compared to their nonchewing peers(同龄 人). According to Johnston, chewing gum reduces stress and anxiety as well as it increases arousal(兴奋).

Researchers say that the studies and research are focused on investigating the effect of chewing gum on focus, alertness, concentration, situational stress, weight control and oral health. According to them, the study is really meaningful and should raise interest in parents “when related to small steps that can lead to better academic performance.” The new study is being built on previous research that was conducted in a laboratory setting and showed that gum chewing can help reduce stress, improve alertness and relieve anxiety. The current findings, for the first time, provide a possible role for chewing gum in helping to improve academic performance in a “real life” classroom setting.

Study leader Craig A. Johnston of the Children's Nutrition Research Center at Baylor College of Medicine in Houston, Texas, and his colleagues studied more than 100 eighthgrade students, 52 girls and 56 boys, aged between 13 and 16 years, in four math classes. The experts randomly(任意地) assigned teenagers into two groups: one group was asked to chew Wrigley's sugarfree gum during class, while doing homework, and also while performing a standardized test. They chewed at least one stick of gum 86 per cent of the time they were in math class and 36 per cent of the time they were doing homework. The participants of the other group did not.
