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(富强), 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 citys population. Many more arrived via the Caribbean and brought with them West Indian cultural traditions. By the mid18th 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：15CABFD.阅读表达阅读下面短文，并依据短文后的要求回答问题(请留意问题后的字数要求)。1Its safe, its simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows.2In what researchers claim is the firstever 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. Theres no shortage of clear evidence about how water might work to control your appetite (食欲). It _ so you dont eat so much; it keeps down your thirst so that you dont turn to calorierich sodas or juices. But until now, the researchers say, there has been no true evidence that waters appetitecontrolling benefits ever translate into actual weight loss. Now there is. In the 12week 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.3Perhaps 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.4The new results today suggest that many people could indeed stand to drink a little more water than they do. But if youre looking to lose weight, be aware that it is actually possible to drink too much water, and you probably wont 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.1What is the main idea of the text？(no more than 8 words)_2Complete the following statement with proper words.(no more than 2 words)Enough obvious evidence _ how your appetite might be under the control of water. 3Fill in the blank in Paragraph 2 with proper words.(no more than 3 words)_4Why should we avoid drinking too much water at a time？(no more than 6 words)_5What does the word “it” (Line 1, Paragraph 1) probably refer to？(no more than 6 words)_答案：1Drinking water can help lose weight. 2has proved3fills you up 4Because it might cause/lead to/result in death. 5Drinking right amounts of water. . 任务型读写阅读下面短文，依据所读内容在表格中的空白处填入恰当的单词。留意：每个空格只填一个单词。Teenagers today live in a very competitive world. It is more important than ever to succeed at school if you hope to have a chance in the job market afterwards. Its no wonder that many young people worry about letting down their parents, their classmates and themselves. In trying to please everyone, they take on too many tasks until it becomes harder and harder to balance homework, parties, sports activities and friends. The result is that young people suffer from stress.There are different ways of dealing with stress. Everyone knows that caffeine, whether it is in the form of coffee or soft drinks, keeps you awake and active. But caffeine is a drug which can become addictive (上瘾). In the end, like other drugs, caffeine only leads to more stress. A better way to deal with stress is to exercise. Research has proved that physical exercise is a good release for stress, because it increases certain chemicals in the brain which calm you down. Making sure you get enough sleep is also an important way of avoiding stress and of staying healthy and full of energy. Another way to avoid stress is to manage your time effectively. It is better to do a few tasks really well than lots of tasks badly. Know your limits and try not to take on too much. Finally, if it all gets beyond your control, dont panic or get hysterical (歇斯底里的). Find the time to sit down quietly and breathe deeply for ten to twenty minutes. Do this regularly, and it will help you calm down.Title: Stressful teenagersThe 1._of teenagerss tressLiving in a very competitive world, teenagers have to be 2._in school hoping to find a good job afterwards.They also worry about disappointing their 3._， their classmates and themselves.
