(2014·宝鸡中学适应性训练) A．The history of the cityB．The city attracted all kinds of immigrants and developed its multi-cultures.C．The brief introduction to New OrleansD．The origin of JazzE．The population of the cityF．African people arrived and they brought their own traditions including music.1．________New Orleans, the city of Louisiana, is one of the most colorful and interesting places in North America. It is well known for its multicultural cuisine(菜肴) and its colonial architecture and is considered by most experts to be the birthplace of jazz, the one music style that the USA can lay claim to inventing.2．________The city was founded in 1718, at a time when France owned that part of North America. Part of its diversity results from the fact that it was subjected to many different influences. France sold Louisiana to Spain in 1763, got it back 40 years later, and almost immediately sold the territory to the USA.3．________As the city prospered(繁荣), it became a magnet(磁铁)for all kinds of immigrants from Europe and other parts of the USA, and was also the first choice destination of breed black slaves. The rich cultural mix led to a relaxed attitude to life and an appreciation of good food, wine, music and dancing. There were frequent festivals.4．________By the end of the 1700s, people of African descent(祖先) made up more than half the city's population. Many more arrived via the Caribbean and brought with them West Indian cultural traditions. By the mid-18th century, black New Orleans people were gathering socially on Sundays at a special market outside the city, where they were able to remember and practice their traditional African dance and drumming music. The roots of jazz can be traced to these events.5．________Native American musicians then combined their music with the African traditions and bands playing a mixture of styles began to perform in street festivals. Europeans came to listen and contribute and the roots of jazz were established. Louis Armstrong, the most famous jazz musician of all time, was influenced by these rich musical mixtures when he heard them in the early years of the 20th century.答案：1－5CABFDⅡ.阅读表达阅读下面短文，并根据短文后的要求回答问题(请注意问题后的字数要求)。
[1]It's safe, it's simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows.[2]In what researchers claim is the first-ever trial of the effect of water consumption on weight loss, scientists from Virginia Tech found that dieters who started each meal with two glasses of water lost nearly five pounds more, on average, than dieters who did not, over the course of 12 weeks. There's no shortage of clear evidence about how water might work to control your appetite (食欲). It ________ so you don't eat so much; it keeps down your thirst so that you don't turn to calorie-rich sodas or juices. But until now, the researchers say, there has been no true evidence that water's appetite-controlling benefits ever translate into actual weight loss. Now there is. In the 12-week study period, dieters instructed to drink water with every meal lost an average of 15.5 pounds; dieters given no instructions lost, on average, just 11 pounds.[3]Perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general. In fact, although doctors and public health authorities regularly remind us to drink more water, very few studies give any insight into what our ideal quantity may be.[4]The new results today suggest that many people could indeed stand to drink a little more water than they do. But if you're looking to lose weight, be aware that it is actually possible to drink too much water, and you probably won't help matters any by drinking too much water at a time. In extreme cases, it can even be deadly. A couple of glasses with each meal, however, should be no problem at all for a healthy person.1．What is the main idea of the text？(no more than 8 words)________________________________________________________________________2．Complete the following statement with proper words.(no more than 2 words)Enough obvious evidence ________________ how your appetite might be under the control of water.3．Fill in the blank in Paragraph 2 with proper words.(no more than 3 words)________________________________________________________________________4．Why should we avoid drinking too much water at a time？(no more than 6 words)________________________________________________________________________5．What does the word “it” (Line 1, Paragr aph 1) probably refer to？(no more than 6 words) ________________________________________________________________________答案：1．Drinking water can help lose weight.2．has proved3．fills you up4．Because it might cause/lead to/result in death.5．Drinking right amounts of water.Ⅲ. 任务型读写阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。

选项中有一项为多余项。
A．Heat food thoroughlyB．Store food properlyC．Cook food thoroughlyD．Serve food safelyE．Prepare food safelyF．Shop smartlyFood Safety in the Home1．________Prevention food poisoning starts with your trip to the supermarket. Pick up your packaged and canned foods first. Buy cans and jars that look perfect. Look for any expiration dates on the labels and never buy outdated food. Likewise, check the “use by” or “sell by” date on da iry products such as cottage cheese, cream cheese, yogurt, and sour cream and pick the ones that will stay fresh longest in your refrigerator.2．________After shopping, get home as soon as you can. Then put food into the refrigerator or freezer right away. Make sure to set the refrigerator temperature to 40℉and the freezer to 0℉. Check temperatures with a thermometer. Place raw meat and seafood in containers in the refrigerator to prevent their juices from dripping on other foods. Eggs always go in the refrigerator.3．________Wash hands and surfaces often. Bacteria can be spreadthroughout the kitchen and get onto cutting boards and counter tops. To prevent this, wash hands with soap and hot water before and after handling food, and after using the bathroom or handling pets. Wash everything else before and after it touches food. Wash cloths before you use them again for anything else.4．________Cook food thoroughly until it is done. For example, cooked red meat looks brown inside. Use a food thermometer to check the internal temperature of meat, poultry, casseroles and other food. Use a thermometer with a small-diameter stem. Insert the thermometer 1 to 2 inches into the center of the food and wait 30 seconds to ensure an accurate measurement. Check temperature in several places to be sure the food is evenly heated.5．________Use clean containers to store and serve food. When a dish is empty or nearly empty, replace with fresh container of food, removing the previous container. Place cold food in containers on some ice. Place the container inside a deep pan filled with ice to keep food cold. Once food is thoroughly heated on stove top, oven or in microwave oven, keep food hot by using a heat source. Place food in chafing dishes, preheated steam tables, warming trays and/or slow cookers.答案：1－5FBECDⅡ.阅读表达阅读下面短文，并根据短文后的要求回答问题(请注意问题后的字数要求)。

Martiniere Girls College.C.BTTS Upper Primary School.D.Aftab English Higher Secondary School.2.What can Kulsoom’s innovation do?A.Warn users against sitting improperly.B.Correct users’ poor standing posture.C.Make users sit still more comfortably.D.Alarm users about falling off a chair.3.Which of the following is targeted specifically at the aged?A.New serving tray.B.Sudden fall detector.C.Posture correcting chair.D.Oxygen/carbon dioxide level indicator.B(四川南充高二期末)When I was a child,I always wanted to be a superhero.I wanted to save the w orld and make everyone happy.But I knew that I’d need superpowers to make my dreams come true.So I used to embark on these imaginary journeys to find intergalactic (星系之间的) objects from planet Krypton,but didn’t yield much result.When I grew up and realized that science fiction was not a good source for superpowers,I decided instead to embark on a journey of real science,to find a more useful truth.I started my journey in California,with a UC Berkeley 30-year longitudinal study that examined the photos of students in an old yearbook,and tried to measure their success and well-being throughout their life.By measuring the students’smiles,researchers were able to predict how fulfilling andlong-lasting a subject’s marriage would be,how well they would score on standardized tests of well-being,and how inspiring they would be to others.Another aha moment came from a Wayne State University span research project that looked into pre-1950s baseball cards of MajorLeague players.The researchers found that the span of a player’s smile could actually assist to predict the span of his life.Players who didn’t smile in their pictures lived an average of only 72.9 years,while players with beaming smiles lived an average of almost 80 years.British researchers found that one smile can generate the same level of brain stimulation as up to 2,000 bars ofchocolate.Wait—the same study found that smiling is as stimulating as receiving up to ￡16,000 in cash.That’s like $25,000 a smile.It’s not bad.And think about it this way:25,000 times 400—children smile as many as 400 times per day—quite a few kids out there feel like Mark Zuckerberg every day.So whenever you want to tap into a superpower that will help you and everyone around you live a longer,healthier,happier life,smile.4.Why did the author shift to pursuing scientific research?A.Because he discovered galactic objects during childhood.B.Because he realized sci-fi couldn’t bring superpowers.C.Because he dreamed of global happiness since youth.D.Because he embarked on these fictional journeys.5.What can we infer from paragraph 4?A.Every child smiles 400 times per day.B.Kids who smile are as rich as Zuckerberg.C.Smiling is equal to eating 2,000 bars of chocolate.D.Smiling can gain stimulation alike receiving cash.6.What’s the author’s attitude towards the effect of smiles on people?A.Positive.B.Doubtful.C.Neutral.D.Indifferent.7.What is the text mainly about?A.The journey to find the truth.B.The hidden power of smiling.C.The secret to a long and healthy life.D.The significance of superhero studies.Ⅱ.七选五(全国甲卷)What is moderation(适度)?Basically,it means eating only as much food as your body needs.You should feel satisfied at the end of a meal,but not too full. 1 But it doesn’t mean saying goodbye to the foods you love.Take your time.It’s important to slow down and think about food as something nutritious rather than just something to eat in between meetings. 2 It actually takes a few minutes for your brain to tell your body that it has had enough food,so eat slowly and stop eating before you feel full.Eat with others whenever possible.Eating alone,especially in front of the TV or computer,often leads to mindless overeating.And be careful about the foods you keep at hand.It’s more challenging to eat in moderation if you have unhealthy snacks at the ready,like cookies. 3Control emotional(情绪的) eating. 4 Many of us also turn to food to deal with unpleasant emotions such as sadness,loneliness,or boredom.But by learning healthier ways to manage emotions,you can regain control over the food you eat and your feelings.5 A healthy breakfast can start your metabolism(新陈代谢),while eating small,healthy meals keeps your energy up all day.Avoid eating late at night.Try to eat dinner earlier and fast for 14-16 hours until breakfast the next morning.Studies suggest that eating on ly when you’re most active and giving your digestive system a long break each day may help to regulate weight.A.Eat properly throughout the day.B.We don’t always eat just to satisfy hunger.C.Don’t swallow a meal on the way to work.D.Most of us need to double the amount we eat.E.Instead,surround yourself with healthy choices.F.For many of us,moderation means eating less than we do now.G.That won’t lead to cheating or giving up on your new eating plan.Ⅲ.完形填空In April last year,I saw a post on the PNP(Pilots N Paws)
